Concentration Risk Disclosure [Text Block] | (10) Business Risk and Credit Risk Concentration Involving Cash The Company had two customers that comprised all the revenue in the three months ended March 31, 2023 and 2022. The Company had three customers that comprised materially of all the revenue for nine months ended March 31, 2023 and 2022. Additionally, the material amount of trade receivables was comprised of one customer. The Company maintains funds in bank accounts that may exceed the limit insured by the Federal Deposit Insurance Corporation of $250 thousand per depositor. The risk of loss attributable to these uninsured balances is mitigated by depositing funds in what we believe to be high credit quality financial institutions. The Company has not experienced any losses in such accounts.
