Basis of Presentation and Significant Accounting Policies [Text Block]	2. PRINCIPLES OF CONSOLIDATION The Company has eight USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions (e.g., share-based compensation valuation, allowance for doubtful accounts, valuation of inventory and intangible assets, warranty reserve, accrued bonus and valuation allowance related to deferred tax assets) that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities at the date of the financial statements and affect the reported amounts of revenues and expenses during the reporting periods. Actual results could materially differ from those estimates. CONCENTRATION OF CREDIT RISK The Company sells its products to a large number of geographically diverse customers.

The realized gains and losses on marketable securities are determined using the specific identification method. ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS The Company carries accounts receivable at historical cost, less an allowance for doubtful accounts. On a periodic basis, the Company evaluates accounts receivable and establishes an allowance for doubtful accounts for estimated losses considering the following factors when determining if collection of a receivable is probable: customer credit-worthiness, past transaction history with the customer, current economic industry trends and changes in customer payment terms.

Costs that the Company incurs to complete the business combination such as investment banking, legal and other professional fees are not Under the acquisition method of accounting for business combinations, if the Company identifies changes to acquired deferred tax asset valuation allowances or liabilities related to uncertain tax positions during the measurement period and they relate to new information obtained about facts and circumstances that existed as of the acquisition date, those changes are considered a measurement period adjustment and the Company records the offset to goodwill. The Company records all other changes to deferred tax asset valuation allowances and liabilities related to uncertain tax positions in current period income tax expense. Refer to Note 4, September 30, 2021. GOODWILL AND INTANGIBLE ASSETS Identifiable intangible assets, which consist of technology, customer relationships, non-compete agreements, patents, tradenames and trademarks, are carried at cost less accumulated amortization.

Earnings Per Share [Text Block]	18. Basic earnings per share are computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period increased to include the number of dilutive potential common shares outstanding during the period. The dilutive effect of outstanding stock options is reflected in diluted earnings per share by application of the treasury stock method, which assumes that the proceeds from the exercise of the outstanding options are used to repurchase common stock at market value. Under the treasury stock method, an increase in the fair market value of the Company’s common stock can result in a greater dilutive effect from potentially dilutive securities. If the Company has losses for the period, the inclusion of potential common stock instruments outstanding would be anti-dilutive. In addition, under the treasury stock method, the inclusion of stock options with an exercise price greater than the per-share market value would be antidilutive. Potential common shares that would be antidilutive are excluded from the calculation of diluted income per share. The following table sets forth the computation of basic and diluted earnings per share: Years Ended September 30, 2021 2020 Net income $ 704 $ 11,874 Basic income per share $ 0.02 $ 0.36 Diluted income per share $ 0.02 $ 0.35 Weighted average shares outstanding - basic 34,409,478 33,220,915 Assumed exercise of dilutive options 1,179,670 871,413 Weighted average shares outstanding - diluted 35,589,148 34,092,328 Potentially diluted securities outstanding at period end excluded from diluted computation as the inclusion would have been antidilutive: Options 1,035,000 893,750 RSU - - Obligation to issue common stock 208,692 - Total 1,243,692 893,750
