Earnings Per Share [Abstract]
Net Loss per Share	Note 11. Net Loss per Share The Company calculates basic net loss per share by dividing net loss by the weighted average number of common shares outstanding during the reporting period. A net loss cannot be diluted so when the Company is in a net loss position, basic and diluted loss per common share are the same. If in the future the Company achieves profitability, the denominator of a diluted earnings per common share calculation will include both the weighted average number of shares outstanding and the number of common stock equivalents, if the inclusion of such common stock equivalents would be dilutive. Dilutive common stock equivalents include warrants, stock options and non-vested restricted stock awards and restricted stock units using the treasury stock method, along with the effect, if any, from outstanding convertible securities. The Company’s outstanding warrants to purchase common stock have participation rights to any dividends that may be declared in the future and are therefore considered to be participating securities. Participating securities have the effect of diluting both basic and diluted earnings per share during periods of income. During periods of loss, no loss is allocated to the participating securities since the holders have no contractual obligation to share in the losses of the Company. Anti-dilutive common share equivalents excluded from the computation of diluted net loss per share at December 31, 2022 consisted of warrants of 1,150,669, stock options of 990, restricted stock awards of 948, and restricted stock units of 61. Anti-dilutive common share equivalents excluded from the computation of diluted net loss per share at December 31, 2021 consisted of warrants of 48,365, stock options of 2,094, restricted stock units of 1,402, restricted stock awards of 3,586 and ESPP shares of 452.

A net loss cannot be diluted so when the Company is in a net loss position, basic and diluted loss per common share are the same. If in the future the Company achieves profitability, the denominator of a diluted earnings per common share calculation will include both the weighted average number of shares outstanding and the number of common stock equivalents, if the inclusion of such common stock equivalents would be dilutive. Dilutive common stock equivalents include warrants, stock options and non-vested restricted stock awards and restricted stock units using the treasury stock method, along with the effect, if any, from outstanding convertible securities.
