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, impairment of long-term investments, inventory valuation, useful lives for property and equipment, impairment of long-lived assets and identified intangible assets, pension and uncertain tax liabilities, and contingencies. Concentration of Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents, restricted cash, short-term investments and accounts receivable. Cash is deposited with high credit quality financial institutions. For cash equivalents, restricted cash 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, short-term investments, long-term investments, accounts receivable and notes and accounts payable. The carrying amounts approximate the fair value due to the short-term maturity of those instruments. Long-term investments in public company equity securities are measured using the quoted market prices. Long-term investments in private company equity securities are measured at cost with adjustments for observable changes in price or impairments. 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 when restricted cash is within a twelve Short-term investments Short-term investment primarily comprises of the time deposits with original maturities between three one Inventories Inventories are stated at the lower of standard cost or net realizable 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.

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 The Company generates revenue primarily from product sales, either directly to a customer or through a distributor. In determining whether a contract exists, the Company evaluates the terms of the arrangement including rights, obligations and payment term, the relationship with the customer or distributor and their ability to pay. At contract inception, the Company assesses the goods and shipping services promised in its contracts with customers and identifies a single performance obligation that the Company satisfies at a point in time. The Company recognizes product revenue from direct end customers and distributors and when the following events have occurred: (a) the Company has transferred physical possession of the products, (b) the Company has a present right to payment, (c) the customer has legal title to the products, and (d) the customer bears significant risks and rewards of ownership of the products. In accordance with the shipping terms specified in the contracts, these criteria are generally met when the products are shipped from the Company’s vendors (such as the “Ex Works” shipping term) or delivered to the customers’ locations (such as the “Delivered Duty Paid” shipping term). Payment for sales to customers is generally due on standard commercial terms. The revenue recognized is adjusted based on an analysis of historical data and contractual terms. These adjustments, which are not In addition, the Company records allowances for accounts receivable that it estimates may not Freight Costs Costs of shipping and handling for delivery of the Company’s products that are reimbursed by customers are included 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 $922,000, $779,000, $734,000 2018, 2017, 2016, $287,000, $158,000, $236,000 2018, 2017 2016, 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 estimates that obligation and recognizes 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 .

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.

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 2018 2017 2016 Net income (loss) (in thousands) $ 2,088 $ (6,145 ) $ (2,986 ) Weighted average shares outstanding (in thousands) – basic 1,300,795 1,288,977 1,282,141 Effect of dilutive securities: Options and RSUs (in thousands) 30,027 - - Weighted average shares outstanding (in thousands) – diluted 1,330,822 1,288,977 1,282,141 Earnings (loss) per share – basic Basic $ - $ - $ - Diluted $ - $ - $ - 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, impairment of long-term investments, inventory valuation, useful lives for property and equipment, impairment of long-lived assets and identified intangible assets, pension and uncertain tax liabilities, and contingencies. |
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, restricted cash, short-term investments and accounts receivable. Cash is deposited with high credit quality financial institutions. For cash equivalents, restricted cash 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, short-term investments, long-term investments, accounts receivable and notes and accounts payable. The carrying amounts approximate the fair value due to the short-term maturity of those instruments.

Revenue from Contract with Customer [Policy Text Block] | Revenue Recognition The Company generates revenue primarily from product sales, either directly to a customer or through a distributor. In determining whether a contract exists, the Company evaluates the terms of the arrangement including rights, obligations and payment term, the relationship with the customer or distributor and their ability to pay. At contract inception, the Company assesses the goods and shipping services promised in its contracts with customers and identifies a single performance obligation that the Company satisfies at a point in time. The Company recognizes product revenue from direct end customers and distributors and when the following events have occurred: (a) the Company has transferred physical possession of the products, (b) the Company has a present right to payment, (c) the customer has legal title to the products, and (d) the customer bears significant risks and rewards of ownership of the products. In accordance with the shipping terms specified in the contracts, these criteria are generally met when the products are shipped from the Company’s vendors (such as the “Ex Works” shipping term) or delivered to the customers’ locations (such as the “Delivered Duty Paid” shipping term). Payment for sales to customers is generally due on standard commercial terms. The revenue recognized is adjusted based on an analysis of historical data and contractual terms. These adjustments, which are not In addition, the Company records allowances for accounts receivable that it estimates may not |
Cost of Goods and Service Sold, Freight Cost, Policy [Policy Text Block] | Freight Costs Costs of shipping and handling for delivery of the Company’s products that are reimbursed by customers are included 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 Expense, Policy [Policy Text Block] | 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. |

Pension and Other Postretirement Plans, Policy [Policy Text Block] | 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 [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 estimates that obligation and recognizes 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. 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% |
Share-based Payment Arrangement [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 . |
