Other Liabilities Disclosure [Abstract]
DERIVATIVE LIABILITIES	DERIVATIVE LIABILITIES As discussed further in Note 14 - Private Placement Investment, in conjunction with the 2012 private placement investment, the Company issued common stock warrants exercisable for up to 1,200,000 shares of common stock at an exercise price of $3.99 per share until February 16, 2018. The warrants were initially classified in stockholders' equity as additional paid-in capital at the allocated amount, net of allocated transaction costs of $1,425,000. Effective October 31, 2012, upon stockholder approval of anti-dilution provisions that reset the warrants’ exercise price if a dilutive issuance occurs, the warrants were reclassified as non-current derivative liabilities. The fair value of the warrants was $4,139,000 at October 31, 2012, with the difference between the fair value and carrying value recorded to additional paid-in capital. Effective as of the reclassification as derivative liabilities, the warrants are re-valued at each reporting date, with changes in fair value recognized in earnings each reporting period as a credit or charge to miscellaneous income (expense). The fair value of the warrants at January 31, 2018 and 2017 was zero and $46,000, respectively. The change in fiscal 2017 and 2016 reflects $46,000 and $159,000, respectively, of miscellaneous income recognized in the consolidated statements of operations as a result of decreases in the fair value of the warrants. The estimated fair value of the warrants liabilities as of January 31, 2017 was computed using the Black-Scholes option pricing model based on the following assumptions: annual volatility of 62.6%, risk-free rate of 0.5%, dividend yield of 0.0% and expected life of one year. The estimated fair value of the warrants liabilities as of January 31, 2018 was computed using the Black-Scholes option pricing model based on the following assumptions: annual volatility of 57.4%, risk-free rate of 0.0%, dividend yield of 0.0% and expected life of zero years.
