Significant inter-company accounts and transactions have been eliminated in consolidation. Use of estimates The preparation of the condensed consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount and valuation of long-lived assets, valuation allowances for deferred tax assets, the determination of stock option expense and the determination of the fair value of stock warrants issued. Actual results could differ from those estimates. Net loss per share Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common share equivalents outstanding for the period determined using the treasury-stock method or the if-converted method, as applicable. For purposes of this calculation, stock options, restricted stock units (RSUs) and warrants to purchase common stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. The following shares underlying outstanding convertible notes, stock options, RSUs and warrants to purchase common stock were anti-dilutive due to a net loss in the periods presented and, therefore, were excluded from the dilutive weighted average securities computation for the three nine September 30 Three Months Ended September 30, Nine Months Ended September 30, Excluded potentially dilutive weighted average securities (1): 2022 2021 2022 2021 Options to purchase common stock 1,009,230 1,038,439 1,018,900 1,115,380 Unvested restricted stock units 3,221,803 3,772,069 3,921,702 4,543,145 Financing warrants to purchase common stock 6,372 6,372 6,372 6,372 Total potential dilutive weighted average securities 4,237,405 4,816,880 4,946,974 5,664,897 ( 1 Securities are presented on a weighted average outstanding calculation as required if the securities were dilutive .

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates ("ASU") of the Financial Accounting Standards Board (“FASB”) and pursuant to the rules and regulations of the SEC. Accordingly, they do not September 30, 2022 three nine September 30, 2022 September 30, 2021 three nine September 30, 2022 September 30, 2021 nine September 30, 2022 September 30, 2021 December 31, 2021 not December 31, 2021 10 February 24, 2022. The results of operations for the three nine September 30, 2022 not may December 31, 2022
Consolidation, Policy [Policy Text Block]	Principles of consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its Subsidiaries, both of which are wholly-owned subsidiaries. Significant inter-company accounts and transactions have been eliminated in consolidation.
Use of Estimates, Policy [Policy Text Block]	Use of estimates The preparation of the condensed consolidated financial statements requires management of the Company to make a number of estimates and assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of expenses during the period. Significant items subject to such estimates and assumptions include the carrying amount and valuation of long-lived assets, valuation allowances for deferred tax assets, the determination of stock option expense and the determination of the fair value of stock warrants issued. Actual results could differ from those estimates.
Earnings Per Share, Policy [Policy Text Block]	Net loss per share Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss by the weighted average number of common share equivalents outstanding for the period determined using the treasury-stock method or the if-converted method, as applicable. For purposes of this calculation, stock options, restricted stock units (RSUs) and warrants to purchase common stock are considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive. The following shares underlying outstanding convertible notes, stock options, RSUs and warrants to purchase common stock were anti-dilutive due to a net loss in the periods presented and, therefore, were excluded from the dilutive weighted average securities computation for the three nine September 30 Three Months Ended September 30, Nine Months Ended September 30, Excluded potentially dilutive weighted average securities (1): 2022 2021 2022 2021 Options to purchase common stock 1,009,230 1,038,439 1,018,900 1,115,380 Unvested restricted stock units 3,221,803 3,772,069 3,921,702 4,543,145 Financing warrants to purchase common stock 6,372 6,372 6,372 6,372 Total potential dilutive weighted average securities 4,237,405 4,816,880 4,946,974 5,664,897 ( 1 Securities are presented on a weighted average outstanding calculation as required if the securities were dilutive
