Long-Term Debt [Text Block]	11. Notes Payable On February 2, 2023, we entered into a $3.75 million Loan and Security Agreement (“the Loan”). The Company had incurred approximately $814,000 of debt acquisition costs associated with the loan including approximately $254,000 in origination and other transaction fees and approximately $484,000 of prepaid interest, which was the total interest due through maturity. These costs were recorded as a reduction to the carrying value of our debt and are amortized to interest expense straight-line over the term of the Loan. Approximately $601,000 of amortization of debt acquisition costs were recorded as interest expense for the twelve months ended January 31, 2024. On August 22, 2023, in connection with the Sale of Klein, the Loan was repaid in full (see Note 2- "Sale of a Subsidiary and Discontinued Operations" for additional details).
