Fair Value Disclosures [Abstract]
Fair Value Measurements and Financial Instruments	Fair Value Measurements and Financial Instruments Using the fair value hierarchy described in FASB ASC 820 "Fair Value Measurements and Disclosures," we valued our cash and cash equivalents using Level 1 inputs that were based on quoted market prices. We believe that the carrying amounts of our other current financial assets (such as accounts receivable) and other current liabilities (including accounts payable, accrued expenses and the current portion of long-term debt) approximate their fair values due to their short-term maturities. As further discussed in Note (17) - "Convertible Preferred Stock," we used Level 3 inputs to value warrants contingently issuable under the terms of our Series B Convertible Preferred Stock. Level 3 inputs are unobservable inputs developed using the best available information under the circumstances. Level 3 inputs are supported by little or no market activity, are significant to the fair value of the assets or liabilities and reflect our assumptions related to how market participants would use similar inputs to price the asset or liability. Upon issuance of the Series B Convertible Preferred Stock on January 22, 2024, and as of January 31, 2024, we determined the fair value of the warrants using the Monte Carlo simulation model with the following assumptions: expected life of six months; risk free rate of 5.2%; expected volatility of 55.0%; and dividend yield of 0%. As of January 31, 2024 and July 31, 2023, other than the cash and cash equivalents and warrants discussed above, we had no other significant assets or liabilities included in our Condensed Consolidated Balance Sheets recorded at fair value, as such term is defined by FASB ASC 820.
