Debt Note [Abstract]
Promissory Note	7. Promissory Note On January 25, 2013, we entered into a Letter Agreement (the “Agreement”) with Morrison & Foerster LLP (“Morrison”). Under the terms of the Agreement, we issued a Promissory Note (the “Note”) in favor of Morrison in the principal amount of $1,125,000. In consideration for the Note, Morrison agreed to waive $1,519,000 of amounts due and payable to Morrison for legal services rendered. The Note bears interest at the rate of 7.5% per annum, but the then outstanding balance will accrue interest at the rate of 10% per annum upon the occurrence of an event of default (as defined in the Note). Beginning March 31, 2013, and on or before the last business day of each calendar month thereafter, we are required to pay all accrued but unpaid interest on the then unpaid amount of outstanding principal. Beginning on February 28, 2014, we are required to pay equal monthly principal installments of approximately $47,000, plus interest. We may prepay the outstanding balance under the Note in full or in part at any time, which prepayment will result in a discount of the then outstanding balance as more fully described in the Note. The Note will mature on February 28, 2016, unless accelerated pursuant to an event of default (as defined in the Note) or upon the consummation of a change of control (as defined in the Note). As a result of the Agreement, we have reclassified the amount due and payable to Morrison from a current liability to long-term debt, except that any payments due under the Letter Agreement within twelve months from the date of the balance sheet will continue to be classified as a current liability. As of April 30, 2013, $231,000 was due under the Letter Agreement within twelve months and classified as a current liability. In consideration for Morrison’s acceptance of the Note in lieu of payment for its legal services, we issued Morrison a warrant to purchase 375,000 shares of our common stock at an exercise price of $0.83 per share. The warrant was exercisable immediately and expires on January 24, 2018. The warrant may be exercised by Morrison with a cash payment or, in lieu thereof, at its election, through a net exercise, as set forth in the warrant. Neither the warrant nor the shares to be issued upon exercise thereof are registered for sale or resale under the Securities Act of 1933, as amended (the “Securities Act”), and have been or will be issued in reliance on an exemption from registration under the Securities Act pursuant to Section 4(2) thereof based on the offering of such securities to one investor and the lack of any general solicitation or advertising in connection with such issuance. We determined that the warrants issued in connection with the Note were equity instruments and did not represent derivative instruments. The fair value of the warrants issued to Morrison was $245,000, based on the Black-Scholes Pricing Model assuming no dividend yield, volatility of 134%, a risk-free interest rate of 0.35%, and an expected life of 5 years. During the nine months ended April 30, 2013, we recorded $25,000 of other expense resulting from the excess of the total cash outflows under the troubled debt restructuring, plus the expense related to the fair value of the warrant issued in conjunction with the debt, over the carrying amount of the Morrison payables prior to the restructuring. During the three and nine months ended April 30, 2013, we paid $22,000 under the terms of the Note.
