Nature of Operations [Text Block]

(1) NATURE OF OPERATIONS

We are an independent designer, manufacturer and marketer of thermal, mechanical and electrical products that are primarily used by semiconductor manufacturers in conjunction with automatic test equipment ("ATE") in the testing of integrated circuits ("ICs" or "semiconductors"). In addition, in recent years, we have begun marketing our thermal products in industries outside the ATE industry, such as the automotive, consumer electronics, defense/aerospace, energy and telecommunications industries.

The consolidated entity is comprised of inTEST Corporation (parent) and our wholly-owned subsidiaries. We have three reportable segments which are also our reporting units: Thermal Products, Mechanical Products and Electrical Products. We manufacture our products in the U.S. Marketing and support activities are conducted worldwide from our facilities in the U.S., Germany and Singapore. On January 16, 2012, Temptronic Corporation ("Temptronic"), a wholly-owned subsidiary of inTEST Corporation, acquired substantially all of the assets and certain liabilities of Thermonics, Inc. ("Thermonics"), a division of Test Enterprises, Inc. The acquisition of the Thermonics business broadens the product line of inTEST's Thermal Products segment. This acquisition is discussed further in Note 3.

The semiconductor industry in which we operate is characterized by rapid technological change, competitive pricing pressures and cyclical market patterns. This industry is subject to significant economic downturns at various times. Our financial results are affected by a wide variety of factors, including, but not limited to, general economic conditions worldwide and in the markets in which we operate, economic conditions specific to the semiconductor industry and the other industries we serve, our ability to safeguard patented technology and intellectual property in a rapidly evolving market, downward pricing pressures from customers, and our reliance on a relatively few number of customers for a significant portion of our sales. In addition, we are exposed to the risk of obsolescence of our inventory depending on the mix of future business and technological changes within the industry. As a result of these or other factors, we may experience significant period-to-period fluctuations in future operating results.

Accounting Policies [Abstract]

Significant Accounting Policies [Text Block]

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Use of Estimates

The accompanying consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated upon consolidation. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain of our accounts, including inventories, long-lived assets, goodwill, identifiable intangibles, deferred income tax valuation allowances and product warranty reserves, are particularly impacted by estimates.

In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position, results of operations, and changes in cash flows for the interim periods presented. Certain footnote information has been condensed or omitted from these consolidated financial statements. Therefore, these consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2012 filed with the Securities and Exchange Commission on March 29, 2013 (the "2012 Form 10-K").

Reclassification

Certain prior period amounts have been reclassified to be comparable with the current period's presentation.

Inventories

Inventories are valued on a first-in, first-out basis, not in excess of market value. Cash flows from the sale of inventories are recorded in operating cash flows. On a quarterly basis, we review our inventories and record excess and obsolete inventory charges based upon our established objective excess and obsolete inventory criteria. These criteria identify material that has not been used in a work order during the prior twelve months and the quantity of material on hand that is greater than the average annual usage of that material over the prior three years. In certain cases, additional excess and obsolete inventory charges are recorded based upon current industry conditions, anticipated product life cycles, new product introductions and expected future use of the inventory. The excess and obsolete inventory charges we record establish a new cost basis for the related inventories. We incurred excess and obsolete inventory charges of $197 and $358 for the six months ended June 30, 2013 and 2012, respectively.

Goodwill, Intangible and Long-Lived Assets

We account for goodwill and intangible assets in accordance with Accounting Standards Codification ("ASC") 350 (Intangibles- Goodwill and Other). Finite-lived intangible assets are amortized over their estimated useful economic life and are carried at cost less accumulated amortization. Goodwill is assessed for impairment at least annually in the fourth quarter, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. As a part of the goodwill impairment assessment, we have the option to perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If we determine this is the case, we are required to perform a two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss, if any, to be recognized. The two-step test is discussed below. If we determine that it is more-likely-than-not that the fair value of the reporting unit is greater than its carrying amounts, the two-step goodwill impairment test is not required.

If we determine it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount as a result of our qualitative assessment, we will perform a quantitative two-step goodwill impairment test. In the Step I test, the fair value of a reporting unit is computed and compared with its book value. If the book value of a reporting unit exceeds its fair value, a Step II test is performed in which the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess. The two-step goodwill impairment assessment is based upon a combination of the income approach, which estimates the fair value of our reporting units based upon a discounted cash flow approach, and the market approach which estimates the fair value of our reporting units based upon comparable market multiples. This fair value is then reconciled to our market capitalization at year end with an appropriate control premium. The determination of the fair value of our reporting units requires management to make significant estimates and assumptions including the selection of appropriate peer group companies, control premiums, discount rate, terminal growth rates, forecasts of revenue and expense growth rates, changes in working capital, depreciation, amortization and capital expenditures. Changes in assumptions concerning future financial results or other underlying assumptions would have a significant impact on either the fair value of the reporting unit or the amount of the goodwill impairment charge.

Indefinite-lived intangible assets are assessed for impairment at least annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of an intangible asset with its carrying amount. If the carrying amount of an intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess.

Long-lived assets, which consist of finite-lived intangible assets and property and equipment, are assessed for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value. The cash flow estimates used to determine the impairment, if any, contain management's best estimates using appropriate assumptions and projections at that time.

Stock-Based Compensation

We account for stock-based compensation in accordance with ASC Topic 718 (Compensation - Stock Compensation) which requires that employee share-based equity awards be accounted for under the fair value method and requires the use of an option pricing model for estimating fair value of stock options granted, which is then amortized to expense over the service periods. See further disclosures related to our stock-based compensation plan in Note 10.

Subsequent Events

We have made an assessment of our operations and determined that there were no material subsequent events requiring adjustment to, or disclosure in, our consolidated financial statements for the six months ended June 30, 2013.

Revenue Recognition

We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collectability is reasonably assured. Sales of our products are made through our sales employees, third-party sales representatives and distributors. There are no differences in revenue recognition policies based on the sales channel. We do not provide our customers with rights of return or exchanges. Revenue is generally recognized upon product shipment. Our customers' purchase orders do not typically contain any customer-specific acceptance criteria, other than that the product performs within the agreed upon specifications. We test all products manufactured as part of our quality assurance process to determine that they comply with specifications prior to shipment to a customer. To the extent that any customer purchase order contains customer-specific acceptance criteria, revenue recognition is deferred until customer acceptance.

With respect to sales tax collected from customers and remitted to governmental authorities, we use a net presentation in our consolidated statement of operations. As a result, there are no amounts included in either our net revenues or cost of revenues related to sales tax.

Product Warranties

We generally provide product warranties and record estimated warranty expense at the time of sale based upon historical claims experience. Warranty expense is included in selling expense in the consolidated financial statements.

Restructuring and Other Charges

We recognize a liability for restructuring charges at fair value only when the liability is incurred. The three main components of our restructuring plans have been related to workforce reductions, the consolidation of excess facilities and asset impairments. Workforce-related charges are accrued when it is determined that a liability has been incurred, which is generally after individuals have been notified of their termination dates and expected severance benefits. Plans to consolidate excess facilities result in charges for lease termination fees and future commitments to pay lease charges, net of estimated future sub-lease income. We recognize these charges when we have vacated the premises. In addition, as a result of plans to consolidate excess facilities, we may incur other associated costs such as charges to relocate inventory, equipment or personnel. We recognize charges for other associated costs when these costs are incurred, which is generally when the goods or services have been provided to us. Assets that may be impaired consist of property, plant and equipment and identifiable intangible assets. Asset impairment charges are based on an estimate of the amounts and timing of future cash flows related to the expected future remaining use and ultimate sale or disposal of the asset.

Income Taxes

The asset and liability method is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for operating loss and tax credit carryforwards and for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the periods in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is more likely than not that such assets will not be realized.

Net Earnings (Loss) Per Common Share

Net earnings (loss) per common share - basic is computed by dividing net earnings (loss) by the weighted average number of common shares outstanding during each period. Net earnings (loss) per common share - diluted is computed by dividing net earnings (loss) by the weighted average number of common shares and common share equivalents outstanding during each period. Common share equivalents represent stock options and unvested shares of restricted stock and are calculated using the treasury stock method. Common share equivalents are excluded from the calculation if their effect is anti-dilutive.

The table below sets forth, for the periods indicated, a reconciliation of weighted average common shares outstanding - basic to weighted average common shares and common share equivalents outstanding - diluted and the average number of potentially dilutive securities that were excluded from the calculation of diluted earnings per share because their effect was anti-dilutive:

	Three Months Ended June 30,				Six Months Ended June 30,
	*2013*		*2012*		*2013*		*2012*
Weighted average common shares outstanding - basic		10,371,716		10,273,812		10,349,695		10,239,463
Potentially dilutive securities:
Employee stock options and unvested shares of restricted stock		22,378		85,845		30,584		102,551
Weighted average common shares and common share equivalents outstanding - diluted		10,394,094		10,359,657		10,380,279		10,342,014

Average number of potentially dilutive securities excluded from calculation		18,462		31,962		28,605		38,811

Effect of Recently Adopted Amendments to Authoritative Accounting Guidance

In July 2012, the FASB issued amendments to existing guidance on the assessment of impairment for indefinite-lived intangible assets other than goodwill. The amendments permit an entity first to assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. However, an entity can choose to adopt this guidance early even if its annual test date is before the issuance of the final standard, provided that the entity has not yet issued its financial statements for the most recent annual or interim period. We adopted these amendments on January 1, 2013. The adoption of these amendments did not have a material impact on our consolidated financial statements.

In February 2013, the FASB issued amendments to existing guidance on the accounting for accumulated other comprehensive income. The amendments require entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. The amendments are effective for annual and interim periods beginning after December 15, 2012. We adopted these amendments on January 1, 2013. The adoption of these amendments did not have a material impact on our consolidated financial statements.

(3) ACQUISITION

On January 16, 2012, Temptronic acquired substantially all of the assets and certain liabilities of Thermonics pursuant to the Asset Purchase Agreement dated December 9, 2011. Thermonics is engaged in the business of designing, manufacturing, selling and distributing temperature forcing systems used in the testing of various products under temperature controlled situations. The acquisition of the Thermonics business broadened the product line of inTEST's Thermal Products segment.

The purchase price for the assets was approximately $3,802 in cash, plus the assumption of specified liabilities, including trade payables and certain customer contract obligations. In connection with this acquisition, we also signed a separate one year lease for the facility occupied by Thermonics in Sunnyvale, California. This facility is owned by certain shareholders of the seller. We ceased operations at this facility in February 2012 and relocated the Thermonics product line to our facility in Mansfield, Massachusetts where our Temptronic operations are located. During 2012, we recorded a restructuring charge of $313 related to this action. See Note 5 for further detail regarding this charge.

Total acquisition costs incurred to complete this transaction were $485. The portion of these costs that was incurred in 2011 was $148. Acquisition costs are expensed as incurred and included in general and administrative expense.

The Thermonics acquisition was accounted for as a purchase business combination and, accordingly, the results of Thermonics have been included in our consolidated results of operations from the date of acquisition. The allocation of the total purchase price of Thermonics net tangible and identifiable intangible assets was based on their estimated fair values as of the acquisition date. The tangible assets acquired include accounts receivable, inventory, and property and equipment. Liabilities assumed include trade payables, certain customer contract obligations and accrued payments under a non-compete/non-solicitation agreement with a former employee of Thermonics. Identifiable intangible assets acquired include customer relationships, customer backlog, the Thermonics trade name, patented technology, and a non-compete/non-solicitation agreement with a former employee of Thermonics. The excess of the purchase price over the identifiable intangible and net tangible assets in the amount of $50 was allocated to goodwill and is deductible for tax purposes. Goodwill is attributed to the synergies that are expected to result from the operations of the combined businesses. The determination of fair value reflects the assistance of third-party valuation specialists, as well as our own estimates and assumptions.

The following represents the allocation of the purchase price:

Goodwill	$	50
Identifable intangible assets		1,728
Tangible assets acquired and liabilities assumed:
Trade accounts receivable		1,161
Inventories		874
Property and equipment		263
Accounts payable		(77	)
Accrued non-compete/non-solicitation payments		(48	)
Accrued sales commissions		(82	)
Accrued warranty		(67	)
Total purchase price	$	3,802

We estimated the fair value of identifiable intangible assets acquired using a combination of the income, cost and market approaches. The following table provides further information about the finite-lived intangible assets acquired in connection with the acquisition of Thermonics as of the acquisition date:

	Fair Value		Weighted Average Estimated Useful Life (in months)
Customer relationships	$	1,110		72
Customer backlog		70		3
Thermonics trade name		140		48
Patented technology		360		132
Non-compete/non-solicitation agreement		48		18

Total intangible assets	$	1,728		78.3

For the period from January 16, 2012 to June 30, 2012, Thermonics contributed $2,044 of net revenues. We do not track net income within our Thermal Products segment by product line. As a result, the net income for Thermonics for the period from January 16, 2012 to June 30, 2012 is not available.

We generally amortize our finite-lived intangible assets over their estimated useful lives on a straightline basis, unless an alternate amortization method can be reliably determined. Any such alternate amortization method would be based on the pattern in which the economic benefits of the intangible asset are expected to be consumed. None of our intangible assets have any residual value. The following table provides further information about the estimated useful lives of our finite-lived intangible assets as of June 30, 2013:

(5) RESTRUCTURING AND OTHER CHARGES

In connection with the acquisition of Thermonics, as discussed further in Note 3, we signed a separate one year lease for the facility in Sunnyvale, California occupied by Thermonics at the time of the acquisition. This facility was owned by certain shareholders of the seller. We ceased operations at this facility in February 2012 and relocated the Thermonics product line to our facility in Mansfield, Massachusetts where our Temptronic operations are located. During the first quarter of 2012, we incurred approximately $359 of facility closure costs related to this action. These costs included lease termination fees of approximately $220 and other costs associated with this consolidation of facilities, including the cost to relocate inventory and equipment, of approximately $139. During the fourth quarter of 2012 we received a refund of $46 of lease termination fees paid in the first quarter due to the sale of the leased facility. Accrued restructuring and other charges are included in Other Current Liabilities on our balance sheet.

Changes in our liability for restructuring and other charges for the six months ended June 30, 2012 are summarized as follows:

(10) STOCK-BASED COMPENSATION

As of June 30, 2013, we had outstanding stock options and unvested restricted stock awards granted under stock-based employee compensation plans that are described more fully in Note 15 to the consolidated financial statements in our 2012 Form 10-K.

As of June 30, 2013, total compensation expense to be recognized in future periods was $172. The weighted average period over which this expense is expected to be recognized is 2.0 years. All of this expense is related to nonvested shares of restricted stock.

Restricted Stock Awards

We record compensation expense for restricted stock awards (nonvested shares) based on the quoted market price of our stock at the grant date and amortize the expense over the vesting period. Restricted stock awards generally vest over four years. The following table shows the allocation of the compensation expense we recorded during the three and six months ended June 30, 2013 and 2012, respectively, related to nonvested shares:

	Three Months Ended June 30,				*Six Months Ended* *June 30,*

(11) EMPLOYEE BENEFIT PLANS

We have a defined contribution 401(k) plan for our employees who work in the U.S. (the "inTEST 401(k) Plan"). All permanent employees of inTEST Corporation, Temptronic (effective January 1, 2013) and inTEST Silicon Valley Corporation who are at least 18 years of age are eligible to participate in the plan. We match employee contributions dollar for dollar up to 10% of the employee's annual compensation, with a maximum limit of $5. Employer contributions vest ratably over four years. Matching contributions are discretionary.

Temptronic adopted a defined contribution 401(k) plan for its domestic employees in 1988, that was merged into the inTEST 401(k) Plan effective September 1, 2002. Prior to January 1, 2013, the inTEST 401(k) Plan retained the matching provisions of the prior Temptronic plan for all Temptronic employees, which included discretionary employer matching contributions of $0.50 on the dollar up to 6% of the employees' annual compensation, with a maximum limit of $3. When the plans were merged, the eligibility and vesting provisions of the prior Temptronic plan were conformed to those for inTEST Corporation and inTEST Silicon Valley Corporation employees.

Prior to January 1, 2013, in addition to the employer matching contributions for which Temptronic employees were eligible, Temptronic employees participating in the inTEST 401(k) plan were also eligible to receive profit sharing contributions which are more fully described in Note 16 to our 2012 Form 10-K. During the third quarter of 2012, our Board of Directors approved an amendment to the inTEST 401(k) Plan. The amendment terminated the profit sharing contributions for Temptronic employees effective December 31, 2012. In addition, the amendment conformed the employer matching provisions for the Temptronic employees with those currently in place for inTEST Corporation and inTEST Silicon Valley employees effective January 1, 2013.

Accounting Policies, by Policy (Policies)	6 Months Ended
Accounting Policies, by Policy (Policies)	Jun. 30, 2013
Accounting Policies [Abstract]
Basis of Presentation and Use of Estimates [Policy Text Block]	*Basis of Presentation and Use of Estimates* The accompanying consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated upon consolidation. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain of our accounts, including inventories, long-lived assets, goodwill, identifiable intangibles, deferred income tax valuation allowances and product warranty reserves, are particularly impacted by estimates. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the financial position, results of operations, and changes in cash flows for the interim periods presented. Certain footnote information has been condensed or omitted from these consolidated financial statements. Therefore, these consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2012 filed with the Securities and Exchange Commission on March 29, 2013 (the "2012 Form 10-K").
Reclassification, Policy [Policy Text Block]	*Reclassification* Certain prior period amounts have been reclassified to be comparable with the current period's presentation.
Inventory, Policy [Policy Text Block]	*Inventories* Inventories are valued on a first-in, first-out basis, not in excess of market value. Cash flows from the sale of inventories are recorded in operating cash flows. On a quarterly basis, we review our inventories and record excess and obsolete inventory charges based upon our established objective excess and obsolete inventory criteria. These criteria identify material that has not been used in a work order during the prior twelve months and the quantity of material on hand that is greater than the average annual usage of that material over the prior three years. In certain cases, additional excess and obsolete inventory charges are recorded based upon current industry conditions, anticipated product life cycles, new product introductions and expected future use of the inventory. The excess and obsolete inventory charges we record establish a new cost basis for the related inventories. We incurred excess and obsolete inventory charges of $197 and $358 for the six months ended June 30, 2013 and 2012, respectively.
Goodwill Intangible and Long Lived Assets [Policy Text Block]	*Goodwill, Intangible and Long-Lived Assets* We account for goodwill and intangible assets in accordance with Accounting Standards Codification ("ASC") 350 (Intangibles- Goodwill and Other). Finite-lived intangible assets are amortized over their estimated useful economic life and are carried at cost less accumulated amortization. Goodwill is assessed for impairment at least annually in the fourth quarter, on a reporting unit basis, or more frequently when events and circumstances occur indicating that the recorded goodwill may be impaired. As a part of the goodwill impairment assessment, we have the option to perform a qualitative assessment to determine whether it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount. If we determine this is the case, we are required to perform a two-step goodwill impairment test to identify potential goodwill impairment and measure the amount of goodwill impairment loss, if any, to be recognized. The two-step test is discussed below. If we determine that it is more-likely-than-not that the fair value of the reporting unit is greater than its carrying amounts, the two-step goodwill impairment test is not required. If we determine it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount as a result of our qualitative assessment, we will perform a quantitative two-step goodwill impairment test. In the Step I test, the fair value of a reporting unit is computed and compared with its book value. If the book value of a reporting unit exceeds its fair value, a Step II test is performed in which the implied fair value of goodwill is compared with the carrying amount of goodwill. If the carrying amount of goodwill exceeds the implied fair value, an impairment loss is recorded in an amount equal to that excess. The two-step goodwill impairment assessment is based upon a combination of the income approach, which estimates the fair value of our reporting units based upon a discounted cash flow approach, and the market approach which estimates the fair value of our reporting units based upon comparable market multiples. This fair value is then reconciled to our market capitalization at year end with an appropriate control premium. The determination of the fair value of our reporting units requires management to make significant estimates and assumptions including the selection of appropriate peer group companies, control premiums, discount rate, terminal growth rates, forecasts of revenue and expense growth rates, changes in working capital, depreciation, amortization and capital expenditures. Changes in assumptions concerning future financial results or other underlying assumptions would have a significant impact on either the fair value of the reporting unit or the amount of the goodwill impairment charge. Indefinite-lived intangible assets are assessed for impairment at least annually in the fourth quarter, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value of an intangible asset with its carrying amount. If the carrying amount of an intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Long-lived assets, which consist of finite-lived intangible assets and property and equipment, are assessed for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets may not be fully recoverable or that the useful lives of these assets are no longer appropriate. Each impairment test is based on a comparison of the estimated undiscounted cash flows to the recorded value of the asset. If impairment is indicated, the asset is written down to its estimated fair value. The cash flow estimates used to determine the impairment, if any, contain management's best estimates using appropriate assumptions and projections at that time.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	*Stock-Based Compensation* We account for stock-based compensation in accordance with ASC Topic 718 (Compensation - Stock Compensation) which requires that employee share-based equity awards be accounted for under the fair value method and requires the use of an option pricing model for estimating fair value of stock options granted, which is then amortized to expense over the service periods. See further disclosures related to our stock-based compensation plan in Note 10.
Subsequent Events, Policy [Policy Text Block]	*Subsequent Events* We have made an assessment of our operations and determined that there were no material subsequent events requiring adjustment to, or disclosure in, our consolidated financial statements for the six months ended June 30, 2013.
Revenue Recognition, Policy [Policy Text Block]	*Revenue Recognition* We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price is fixed or determinable, and collectability is reasonably assured. Sales of our products are made through our sales employees, third-party sales representatives and distributors. There are no differences in revenue recognition policies based on the sales channel. We do not provide our customers with rights of return or exchanges. Revenue is generally recognized upon product shipment. Our customers' purchase orders do not typically contain any customer-specific acceptance criteria, other than that the product performs within the agreed upon specifications. We test all products manufactured as part of our quality assurance process to determine that they comply with specifications prior to shipment to a customer. To the extent that any customer purchase order contains customer-specific acceptance criteria, revenue recognition is deferred until customer acceptance. With respect to sales tax collected from customers and remitted to governmental authorities, we use a net presentation in our consolidated statement of operations. As a result, there are no amounts included in either our net revenues or cost of revenues related to sales tax.
Standard Product Warranty, Policy [Policy Text Block]	*Product Warranties* We generally provide product warranties and record estimated warranty expense at the time of sale based upon historical claims experience. Warranty expense is included in selling expense in the consolidated financial statements.
Restructuring and Other Charges [Policy Text Block]	*Restructuring and Other Charges* We recognize a liability for restructuring charges at fair value only when the liability is incurred. The three main components of our restructuring plans have been related to workforce reductions, the consolidation of excess facilities and asset impairments. Workforce-related charges are accrued when it is determined that a liability has been incurred, which is generally after individuals have been notified of their termination dates and expected severance benefits. Plans to consolidate excess facilities result in charges for lease termination fees and future commitments to pay lease charges, net of estimated future sub-lease income. We recognize these charges when we have vacated the premises. In addition, as a result of plans to consolidate excess facilities, we may incur other associated costs such as charges to relocate inventory, equipment or personnel. We recognize charges for other associated costs when these costs are incurred, which is generally when the goods or services have been provided to us. Assets that may be impaired consist of property, plant and equipment and identifiable intangible assets. Asset impairment charges are based on an estimate of the amounts and timing of future cash flows related to the expected future remaining use and ultimate sale or disposal of the asset.
Income Tax, Policy [Policy Text Block]	*Income Taxes* The asset and liability method is used in accounting for income taxes. Under this method, deferred tax assets and liabilities are recognized for operating loss and tax credit carryforwards and for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the periods in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period that includes the enactment date. A valuation allowance is recorded to reduce the carrying amounts of deferred tax assets if it is more likely than not that such assets will not be realized.
Earnings Per Share, Policy [Policy Text Block]	*Net Earnings (Loss) Per Common Share* Net earnings (loss) per common share - basic is computed by dividing net earnings (loss) by the weighted average number of common shares outstanding during each period. Net earnings (loss) per common share - diluted is computed by dividing net earnings (loss) by the weighted average number of common shares and common share equivalents outstanding during each period. Common share equivalents represent stock options and unvested shares of restricted stock and are calculated using the treasury stock method. Common share equivalents are excluded from the calculation if their effect is anti-dilutive. The table below sets forth, for the periods indicated, a reconciliation of weighted average common shares outstanding - basic to weighted average common shares and common share equivalents outstanding - diluted and the average number of potentially dilutive securities that were excluded from the calculation of diluted earnings per share because their effect was anti-dilutive:
New Accounting Pronouncements, Policy [Policy Text Block]	*Effect of Recently Adopted Amendments to Authoritative Accounting Guidance* In July 2012, the FASB issued amendments to existing guidance on the assessment of impairment for indefinite-lived intangible assets other than goodwill. The amendments permit an entity first to assess qualitative factors to determine whether it is more likely than not that an indefinite-lived intangible asset is impaired as a basis for determining whether it is necessary to perform the quantitative impairment test. If an entity believes, as a result of its qualitative assessment, that it is more-likely-than-not that the fair value is less than its carrying amount, the quantitative impairment test is required. Otherwise, no further testing is required. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. However, an entity can choose to adopt this guidance early even if its annual test date is before the issuance of the final standard, provided that the entity has not yet issued its financial statements for the most recent annual or interim period. We adopted these amendments on January 1, 2013. The adoption of these amendments did not have a material impact on our consolidated financial statements. In February 2013, the FASB issued amendments to existing guidance on the accounting for accumulated other comprehensive income. The amendments require entities to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the financial statements or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified in its entirety in the same reporting period. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. The amendments are effective for annual and interim periods beginning after December 15, 2012. We adopted these amendments on January 1, 2013. The adoption of these amendments did not have a material impact on our consolidated financial statements.
