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, 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. For the year ended December 31, 2020, two 14% 11%, two 9% 19%, December 31, 2020. December 31, 2019, two 14% 12%, two 13% 21%, December 31, 2019. Additionally, for the year ended December 31, 2020, four 32%, 19%, 11% 10% four 18%, 23%, 18%, 12% December 31, 2020. December 31, 2019, two 34% 19% two 23% 32%, December 31, 2019. 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 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 listed companies over which the Company does not Long-term investments, including non-marketable equity investments and interests in venture capital funds, are measured at cost with adjustments for observable changes in price or impairments because those investments in equity securities do not 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 Leases On January 1, 2019, 842, not January 1, 2019 842, 840, Under ASC 842, not not Payments for leases of low-value assets under the Company's capitalization policy and short-term leases with a lease term less than 12 Under ASC 840, For lease arrangements where the Company is the lessor, the Company recognizes lease income from operating leases on a straight-line basis over the lease term 842 ASC840. 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 Product Sales 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.

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 non-operating income or loss. 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.

Earnings Per Share [Text Block] | 16. 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 (loss) income 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 2020 2019 2018 Net income (loss) (in thousands) $ 6,127 $ (5,039 ) $ 2,088 Weighted average shares outstanding (in thousands) – basic 1,348,899 1,316,032 1,300,795 Effect of dilutive securities: Options and RSUs (in thousands) 87,309 - 30,027 Weighted average shares outstanding (in thousands) – diluted 1,436,208 1,316,032 1,330,822 Earnings (loss) per share Basic $ - $ - $ - Diluted $ - $ - $ - Certain outstanding options and RSUs were excluded from the computation of diluted EPS since their effect would have been anti-dilutive.

Revenue from Contract with Customer [Policy Text Block] | Revenue Recognition Product Sales 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 Licensing revenue The Company recognizes licensing revenues when the Company satisfies a performance obligation by transferring a promised service (that is, an asset) to a customer.

As most of the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the rate of interest the Company would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. |
