Derivatives	3 We may enter into foreign exchange forward contracts to hedge against the effect of exchange rate fluctuations on cash flows denominated in foreign currencies associated with our subsidiary in Singapore. These transactions are designated as cash flow hedges and are recorded in the accompanying consolidated balance sheets at fair value. The effective portion of the gain or loss on these derivatives is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period during which the hedged transaction affects earnings. Gains and losses on the derivatives representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. The maximum length of time over which we hedge our exposure to the variability in future cash flows is 12 There were no open cash flow hedges at December 31, 2016 months ended September 30, 2017 nine months ended September 30, 2016 edge ineffectiveness and the amounts excluded from effectiveness testing recognized in earnings on cash flow hedges were not material.

Fair Value Disclosures [Abstract]
Fair Value Measurements	4 ASUREMENTS: We determine the fair value of our assets and liabilities based on the exchange price that would be received for an asset or paid to transfer a liability (i.e., the exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. We use a fair value hierarchy with three two 1 active 2 3 The following provides information regarding fair value measurements for our marketable securities as of September 30, 2017 December 31, 2016 three Fair Value Measurements at September 30, 2017 (In thousands) Balance September 30, 2017 Quoted Prices 1 Significant 2 Significant 3 Marketable securities: U.S. government and agency obligations $ 9,199 $ — $ 9,199 $ — Corporate debt securities and certificates of deposit 3,225 — 3,225 — Asset backed securities 3,142 — 3,142 — Equity security 84 84 — — Total marketable securities $ 15,650 $ 84 $ 15,566 $ — Fair Value Measurements at December 31, 2016 (In thousands) Balance December 31, 2016 Quoted Prices 1 Significant 2 Significant 3 Marketable securities: U.S. government and agency obligations $ 9,812 $ — $ 9,812 $ — Corporate debt securities and certificates of deposit 3,620 — 3,620 — Asset backed securities 1,736 — 1,736 — Equity security 53 53 — — Total marketable securities $ 15,221 $ 53 $ 15,168 $ — During the nine months ended September 30, 2017 and the year ended December 31, 2016 , there were no transfers within the three The fair value for our U.S. government and agency obligations, corporate debt securities and certificates of deposit and asset backed securities are determined based on valuations provided by external investment managers which obtain them from a variety of industry standard data providers. The fair value for our equity security is based on a quoted market price obtained from an active market. The carrying amounts of financial instruments such as cash equivalents, accounts receivable, other assets, accounts payable, advance customer payments, accrued expenses and other liabilities are approximately equal to their related fair values due to their short-term maturities. Non-financial assets such as equipment and leasehold improvements, goodwill and intangible assets are subject to non-recurring fair value measurements if they are deemed impaired. We had no re-measurements of non-financial assets to fair value in the nine months ended September 30, 2017 or the nine months ended September 30, 2016 .

Accounting For Stock-Based Compensation	5 We have three stock-based compensation plans that are administered by the Compensation Committee of the Board of Directors. We have an Employee Stock Incentive Plan for officers, other employees, consultants and independent contractors under which we have granted options and restricted stock units to officers and other employees, an Employee Stock Purchase Plan under which shares of our common stock may be acquired by employees at discounted prices, and a Non-Employee Director Stock Plan that provides for automatic grants of shares of our common stock to non-employee directors. New shares of our common stock are issued upon stock option exercises, vesting of restricted stock units, issuances of shares to board members and issuances of shares under the Employee Stock Purchase Plan. Employee Stock Incentive Plan As of September 30, 2017 , there were 429,939 shares of common stock reserved in the aggregate for issuance pursuant to future awards under our Employee Stock Incentive Plan and 530,174 shares of common stock reserved in the aggregate for issuance pursuant to outstanding awards under our Employee Stock Incentive Plan. Although our Compensation Committee has authority to issue options, restricted stock, restricted stock units, share grants and other share based benefits under our Employee Stock Incentive Plan, to date only restricted stock units and stock options have been granted under the plan. Options have been granted at an option price per share equal to the market value of our common stock on the date of grant, vest over a four year period and expire seven years after the date of grant. Restricted stock units vest over a four year period and entitle the holders to one share of our common stock for each restricted stock unit. Reserved shares underlying outstanding awards, including options and restricted shares, that are forfeited are available under the Employee Stock Incentive Plan for future grants. Non-Employee Director Stock Plan As of September 30, 2017 shares of common stock reserved in the aggregate for issuance pursuant to future awards under our Non-Employee Director Stock Plan and 16,000 shares of common stock reserved in the aggregate for issuance pursuant to outstanding stock option awards under our Non-Employee Director Stock Plan. Under the terms of the plan, each non-employee director will automatically be granted 2,000 shares of our common stock on the date of each annual meeting at which such director is elected to serve on the board . At our May 11, 2017 annual meeting, our shareholders, upon recommendation of the Board of Directors, approved amendments to the Non-Employee Director Stock Plan that eliminated annual stock option grants for non-employee directors and provide for share grants under the Non-Employee Director Stock Plan which will vest in four Pursuant to the plan, on the date of our 2017 8,000 167,000 As of September 30, 2017 September 30, 2017 Pursuant to the original plan, on the date of our 2016 136,000 8.71 one Stock Option Activity The following is a summary of stock option activity in the nine months ended September 30, 2017 : Options Outstanding Weighted Average Exercise Outstanding, December 31, 2016 547,625 $ 9.39 Granted — — Exercised (42,000 ) 9.24 Expired — — Forfeited — — Outstanding, September 30, 2017 505,625 $ 9.41 Exercisable, September 30, 2017 229,063 $ 7.67 The intrinsic value of an option is the amount by which the market price of the underlying stock exceeds the option's exercise price.

While we engage in extensive product quality programs and processes, including actively monitoring and evaluating the quality of component suppliers, warranty obligations are affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. If actual product failure rates, material usage or service delivery costs differ from our estimates, revisions to the estimated warranty liability would be required and could be material.

Earnings Per Share [Abstract]
Net Income (loss) Per Share	10. NET INCOME (LOSS) PER SHARE: Basic net income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Net income per diluted share is computed by dividing net income by the weighted average number of common and common equivalent shares outstanding during the period. Common equivalent shares consist of shares of common stock to be issued upon exercise of stock options, the vesting of restricted shares and restricted stock units and the purchase of shares under our Employee Stock Purchase Plan, as calculated using the treasury stock method. All common equivalent shares were excluded from the calculation of net loss per diluted share in the three months ended September 30, 2017 due to their anti-dilutive effect.

A deferred tax asset generally represents future tax benefits to be received when temporary differences previously reported in our consolidated financial statements become deductible for income tax purposes, when net operating loss carry forwards are applied against future taxable income, or when tax credit carry forwards are utilized on our tax returns. We assess the realizability of our deferred tax assets and the need for a valuation allowance based on the guidance provided in current financial accounting standards. Significant judgment is required in determining the realizability of our deferred tax assets. The assessment of whether valuation allowances are required considers, among other matters, the nature, frequency and severity of any current and cumulative losses, forecasts of future profitability, the duration of statutory carry forward periods, our experience with loss carry forwards not expiring unused and tax planning alternatives. In analyzing the need for valuation allowances, we first considered our history of cumulative operating results for income tax purposes over the past three years in each of the tax jurisdictions where we operate, our financial performance in recent quarters, statutory carry forward periods and tax planning alternatives. Finally, we considered both our near-term and long-term financial outlook. After considering all available evidence both positive and negative, we concluded that recognition of valuation allowances for substantially all of our U.S. and Singapore deferred tax assets was not required at September 30, 2017.

Contingencies	14 We are periodically a defendant in miscellaneous claims and disputes in the ordinary course of business. While the outcome of these matters cannot be predicted with certainty, management presently believes the disposition of these matters will not have a material effect on our financial position, results of operations or cash flows. In the normal course of business to facilitate sales of our products and services, we at times indemnify other parties, including customers, with respect to certain matters. In these instances, we have agreed to hold the other parties harmless against losses arising out of intellectual property infringement or other types of claims. These agreements may limit the time within which an indemnification claim can be made, and almost always limit the amount of the claim. It is not possible to determine the maximum potential liability under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular agreement. Historically, payments made, if any, under these agreements have not had a material impact on our operating results, financial position or cash flows.

Accounting Changes and Error Corrections [Abstract]
Adoption Of Accounting Standards Update No. 2016-09, Improvements To Employee Share Based Payment Accounting	15 ADOPTION OF ACCOUNTING STANDARDS UPDATE NO. 2016 09 IMPROVEMENTS TO EMPLOYEE SHARE-BASED PAYMENT ACCOUNTING: O n January 1, 2017, we adopted ASU No. 2016 09 Improvements to Employee Share-Based Payment Accounting 2016 09 . At January 1, 2017, we had excess tax benefits from employee share-based payments that were not recognized because current taxes payable had not been reduced. Under the new guidance, we are required to recognize the excess tax benefits regardless of whether or not they reduce income taxes payable in the current period. The new guidance also requires all excess tax benefits and tax deficiencies to be recognized as income tax expense or benefit in our statement of operations. Prior to our adoption of ASU No. 2016 09 Recognition of the deferred tax assets for previously unrecognized excess tax benefits and the impact of additional stock compensation expense resulting from the change in the accounting for stock option forfeitures were required to be applied using a modified retrospective approach. At January 1, 2017, we recorded a $278,000 credit to retained earnings and a corresponding debit to deferred tax assets for previously unrecognized excess tax benefits. We also recorded a $23,000 credit to common stock, a $16,000 debit to retained earnings and a $7,000 debit to deferred tax assets for additional stock compensation expense related to the change in accounting for stock option forfeitures. Our income tax provision in the nine months ended September 30, 2017, includes a $207,000 excess tax benefit from employee share-based payments. The impact of the change in accounting for stock option forfeitures on stock compensation expense in the nine months ended September 30, 2017 was inconsequential. ASU 2016 09 ASU 2016 09
