Significant Accounting Policies [Text Block] | 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated on consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Significant accounting estimates reflected in the Company’s consolidated financial statements include valuation allowance for deferred income tax assets, allowance for doubtful accounts, other-than-temporary impairment of securities, inventory valuation, useful lives for property and equipment, impairment of long-lived assets and identified intangible assets, allowances for sales returns, pension and uncertain tax liabilities, contingencies and stock-based compensation. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents, short-term investments and accounts receivable. Cash is deposited with high credit quality financial institutions. For cash equivalents and short-term investments, the Company invests primarily in time deposits at the banks with good credit rating. For accounts receivable, the Company performs ongoing credit evaluations of its customers’ financial condition and the Company maintains an allowance for doubtful accounts based upon a review of the expected collectability of individual accounts. Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, restricted cash, accounts receivable, and notes and accounts payable. The carrying amounts approximate the fair value due to the short-term maturity of those instruments. Fair value of available-for-sale investments including short-term investments and long-term investments is based on quoted market prices. Long-term investments in private company equity securities are accounted for under the cost method because the Company does not Cash and Cash Equivalents The Company considers all highly liquid investments with maturities of not three three Restricted Cash The Company classifies deposits made for customs and cash pledged to a bank for the issuance of letters of credit as restricted cash. The deposits are classified as current assets if refundable within a twelve Short-term Investments The Company maintains its excess cash in time deposits, government, corporate, or other agency bonds issued with high credit ratings. The specific identification method is used to determine the cost of securities sold, with realized gains and losses reflected in non-operating income and expenses. All the above-mentioned investments except for time deposits were classified as available-for-sale securities and were recorded at fair value. Unrealized gains and losses on these investments are included in accumulated other comprehensive income and loss as a separate component of shareholders’ equity, net of any related tax effect, unless unrealized losses are deemed other-than-temporary. Unrealized losses are recorded as a charge to income when deemed other-than-temporary. There were no December 31, 2017 2016. Investment transactions are recorded on the trade date. Inventories Inventories are stated at the lower of standard cost or market value. The cost of inventories comprises cost of purchasing raw materials and where applicable, those overheads that have been incurred in bringing the inventories to their present location and condition. Cost is determined on a currently adjusted standard basis, which approximates actual cost on a first first Long-term Investments Long-term investments in private companies over which the Company does not not Long-term investments in listed companies are classified as available-for-sale securities and are recorded at fair value. Unrealized gains and losses on these investments are included in accumulated other comprehensive income and loss as a separate component of shareholders’ equity, net of any related tax effect, unless unrealized losses are deemed other-than-temporary. Unrealized losses are recorded as a charge to income when deemed other-than-temporary. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Major additions and betterments are capitalized, while maintenance and repairs are expensed as incurred. Depreciation is computed on a straight-line basis over estimated service lives that range as follows: buildings - 35 50 3 7 3 7 2 5 5 Long-lived Asset Impairment The Company evaluates the recoverability of long-lived assets whenever events or changes in circumstances indicate the carrying value may not Treasury Stock The Company may may not Revenue Recognition Revenue from product sales to customers, other than distributors, is recognized at the time of shipment and when title and right of ownership transfers to customers. The four Allowances for sales returns and discounts are provided at the time of the recognition of the related revenues on the basis of experience and these provisions are deducted from sales. In certain limited instances, the Company sells its products through distributors. Since the title and risk have not third Freight Costs Costs of shipping and handling for delivery of the Company’s products that are reimbursed by customers are recorded as revenue in the consolidated statements of operations and comprehensive income. Shipping and handling costs are charged to cost of sales as incurred. Research and Development Research and development costs consist of expenditures incurred during the course of planned research and investigation aimed at the discovery of new knowledge and intellectual property that will be useful in developing new products or processes, or at significantly enhancing existing products or production processes as well as expenditures incurred for the design and testing of product alternatives or construction of prototypes. All expenditures related to research and development activities of the Company are charged to operating expenses when incurred. Advertising Expenses The Company expenses all advertising and promotional costs as incurred. These costs were approximately $779,000, $734,000, $782,000 2017, 2016, 2015, $158,000, $236,000, $236,000 2017, 2016, 2015, Pension Costs For employees under defined contribution pension plans, pension costs are recorded based on the actual contributions made to employees’ pension accounts. For employees under defined benefit pension plans, pension costs are recorded based on the actuarial calculation. Government Grants Government grants received by the Company to assist with specific research and development activities are recognized as non-operating income. If the Company has an obligation to repay any of the funds provided by government grants regardless of the outcome of the research and development, the Company will estimate that obligation and recognize the amount as a liability. Income Tax The provision for income tax represents income tax paid and payable for the current year plus the changes in the deferred income tax assets and liabilities during the relevant years. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. The Company believes that uncertainty exists regarding the realizability of certain deferred income tax assets and, accordingly, has established a valuation allowance for those deferred income tax assets to the extent the realizability is not not. The Company utilizes a two first not second 50% Stock-based Compensation The Company grants stock options to its employees and certain non-employees and estimates the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service periods. The Company has elected to use the Black-Scholes option pricing model to determine the fair value of stock options on the date of grant. The Company also grants RSUs to its employees and the RSUs are measured based on the fair market value of the underlying stock on the date of grant. Foreign Currency Transactions The functional currency is the local currency of the respective entities. Foreign currency transactions are recorded at the rate of exchange in effect when the transaction occurs. Gains or losses, resulting from the application of different foreign exchange rates when cash in foreign currency is converted into the entities’ functional currency, or when foreign currency receivable and payable are settled, are credited or charged to income in the period of conversion or settlement. At year-end, the balances of foreign currency monetary assets and liabilities are recorded based on prevailing exchange rates and any resulting gains or losses are credited or charged to income. Translation of Foreign Currency Financial Statements The reporting currency of the Company is the US dollar. Accordingly, the financial statements of the foreign subsidiaries are translated into US dollars at the following exchange rates: assets and liabilities - current rate on balance sheet date; shareholders’ equity - historical rate; income and expenses - weighted average rate during the year. The resulting translation adjustment is recorded as a separate component of shareholders’ equity. Comprehensive Income (Loss) Comprehensive income (loss) represents net income (loss) plus the results of certain changes in shareholders’ equity during a period from non-owner sources . Legal Contingencies Periodically, the Company reviews the status of each significant matter and assesses the potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, the Company accrues a liability for the estimated loss. In view of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, the Company reassesses the potential liability related to the pending claims and litigation and revises these estimates as appropriate. Such revisions in the estimates of the potential liabilities could have a material impact on the results of operations and financial position.

Fair Value Disclosures [Text Block] | 3. FAIR VALUE MEASUREMENTS The Company measures its cash equivalents and marketable securities at fair value. Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The Company measures its cash equivalents and marketable securities at fair value. The Company also determines the fair value of long-term investments and long-lived assets whenever events or changes in circumstances indicate the carrying value may not three Level 1 Level 2 Level 3 no Assets and liabilities measured at fair value on recurring and nonrecurring bases were as follows: (In Thousands) Fair Value Measurements at the End of the Reporting Period Level 1 Level 2 Level 3 Total Items measured at fair value on a recurring basis at December 31, 2017 Cash and cash equivalents Money market mutual funds $ - $ 163 $ - $ 163 Items measured at fair value on a recurring basis at December 31, 2016 Cash and cash equivalents Money market mutual funds $ - $ 162 $ - $ 162 Items measured at fair value on a nonrecurring basis (nil at December 31, 2017 and 2016) The Company utilized a pricing service to estimate fair value measurements for the money market mutual funds. The pricing service utilized market quotations for fixed maturity securities that had quoted prices in active markets. Fixed maturity securities generally traded daily on dealer bids rather than bids recorded on exchanges. The pricing service prepared estimates of fair value measurements for these securities using its proprietary pricing applications which included available relevant market information, benchmark curves, benchmarking of like securities, sector groupings and matrix pricing. Since most of the fixed maturity securities had maturities of one not may The fair value estimates provided by the pricing service for the Company’s investments were based on observable market information rather than market quotes.

Earnings Per Share [Text Block] | 15. EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share is calculated by dividing net income (loss) by the weighted average number of ordinary shares outstanding during the period. Diluted earnings (loss) per share is calculated by dividing net income (loss) by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the period, using the treasury stock method for options. A reconciliation of the numerator and denominator of basic and diluted earnings (loss) per share calculations was as follows: Years Ended December 31 2017 2016 2015 Net loss (in thousands) $ (6,145 ) $ (2,986 ) $ (21,095 ) Weighted average shares outstanding (in thousands) – basic 1,288,977 1,282,141 1,301,465 Effect of dilutive securities: Options and RSUs (in thousands) - - - Weighted average shares outstanding (in thousands) – diluted 1,288,977 1,282,141 1,301,465 Loss per share – basic and diluted $ - $ - $ (0.02 ) Certain outstanding options and RSUs were excluded from the computation of diluted EPS since their effect would have been anti-dilutive.

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated on consolidation. |
Use of Estimates, Policy [Policy Text Block] | Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results could differ from those estimates. Significant accounting estimates reflected in the Company’s consolidated financial statements include valuation allowance for deferred income tax assets, allowance for doubtful accounts, other-than-temporary impairment of securities, inventory valuation, useful lives for property and equipment, impairment of long-lived assets and identified intangible assets, allowances for sales returns, pension and uncertain tax liabilities, contingencies and stock-based compensation. |
Concentration Risk, Credit Risk, Policy [Policy Text Block] | Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents, short-term investments and accounts receivable. Cash is deposited with high credit quality financial institutions. For cash equivalents and short-term investments, the Company invests primarily in time deposits at the banks with good credit rating. For accounts receivable, the Company performs ongoing credit evaluations of its customers’ financial condition and the Company maintains an allowance for doubtful accounts based upon a review of the expected collectability of individual accounts. |
Fair Value of Financial Instruments, Policy [Policy Text Block] | Fair Value of Financial Instruments The Company’s financial instruments include cash and cash equivalents, restricted cash, accounts receivable, and notes and accounts payable. The carrying amounts approximate the fair value due to the short-term maturity of those instruments. Fair value of available-for-sale investments including short-term investments and long-term investments is based on quoted market prices.

All the above-mentioned investments except for time deposits were classified as available-for-sale securities and were recorded at fair value. Unrealized gains and losses on these investments are included in accumulated other comprehensive income and loss as a separate component of shareholders’ equity, net of any related tax effect, unless unrealized losses are deemed other-than-temporary. Unrealized losses are recorded as a charge to income when deemed other-than-temporary. There were no December 31, 2017 2016. Investment transactions are recorded on the trade date. |

Government Grants [Policy Text Block] | Government Grants Government grants received by the Company to assist with specific research and development activities are recognized as non-operating income. If the Company has an obligation to repay any of the funds provided by government grants regardless of the outcome of the research and development, the Company will estimate that obligation and recognize the amount as a liability. |
Income Tax, Policy [Policy Text Block] | Income Tax The provision for income tax represents income tax paid and payable for the current year plus the changes in the deferred income tax assets and liabilities during the relevant years. Deferred income tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amount of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards.

Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block] | Stock-based Compensation The Company grants stock options to its employees and certain non-employees and estimates the fair value of share-based payment awards on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected to vest is recognized as expense ratably over the requisite service periods. The Company has elected to use the Black-Scholes option pricing model to determine the fair value of stock options on the date of grant. The Company also grants RSUs to its employees and the RSUs are measured based on the fair market value of the underlying stock on the date of grant. |
Foreign Currency Transactions and Translations Policy [Policy Text Block] | Foreign Currency Transactions The functional currency is the local currency of the respective entities. Foreign currency transactions are recorded at the rate of exchange in effect when the transaction occurs. Gains or losses, resulting from the application of different foreign exchange rates when cash in foreign currency is converted into the entities’ functional currency, or when foreign currency receivable and payable are settled, are credited or charged to income in the period of conversion or settlement. At year-end, the balances of foreign currency monetary assets and liabilities are recorded based on prevailing exchange rates and any resulting gains or losses are credited or charged to income. |
Translation Of Foreign Currency Financial Statements Policy [Policy Text Block] | Translation of Foreign Currency Financial Statements The reporting currency of the Company is the US dollar. Accordingly, the financial statements of the foreign subsidiaries are translated into US dollars at the following exchange rates: assets and liabilities - current rate on balance sheet date; shareholders’ equity - historical rate; income and expenses - weighted average rate during the year. The resulting translation adjustment is recorded as a separate component of shareholders’ equity. |
Comprehensive Income, Policy [Policy Text Block] | Comprehensive Income (Loss) Comprehensive income (loss) represents net income (loss) plus the results of certain changes in shareholders’ equity during a period from non-owner sources . |
Legal Contingencies Policy [Policy Text Block] | Legal Contingencies Periodically, the Company reviews the status of each significant matter and assesses the potential financial exposure. If the potential loss from any claim or legal proceeding is considered probable and the amount can be estimated, the Company accrues a liability for the estimated loss. In view of uncertainties related to these matters, accruals are based only on the best information available at the time. As additional information becomes available, the Company reassesses the potential liability related to the pending claims and litigation and revises these estimates as appropriate. Such revisions in the estimates of the potential liabilities could have a material impact on the results of operations and financial position. As part of its standard terms and conditions, the Company offers limited indemnification to third not third third third third may not may |
