Commitments and Contingencies Disclosure [Text Block]	10. Commitments and Contingencies Purchase Commitments with Suppliers We generally issue purchase orders to our suppliers with delivery dates from four to six weeks from the purchase order date. In addition, we regularly provide significant suppliers with rolling six-month forecasts of material and finished goods requirements for planning and long-lead time parts procurement purposes only. We are committed to accepting delivery of materials pursuant to our purchase orders subject to various contract provisions that allow us to delay receipt of such order or allow us to cancel orders beyond certain agreed lead times. Such cancellations may or may not include cancellation costs payable by us. In the past, we have been required to take delivery of materials from our suppliers that were in excess of our requirements, and we have previously recognized charges and expenses related to such excess material. If we are unable to adequately manage our suppliers and adjust such commitments for changes in demand, we may incur additional inventory expenses related to excess and obsolete inventory. Such expenses could have a material adverse effect on our business, consolidated results of operations, and financial position. Our fixed purchase commitments at June 3, 2013 totaled approximately $1.1 million. Executive Severance Commitments We have severance compensation agreements with certain of our key executives. These agreements require us to pay these executives, in the event of a termination of employment following a change of control of the Company or other circumstances, the amount of their then current annual base salary and the amount of any bonus amount the executive would have achieved for the year in which the termination occurs plus the acceleration of unvested options. We have not recorded any liability in the consolidated financial statements for these agreements. Although the contemplated sale of shares of common stock and the issuance of the Warrants and possible issuance of the Additional Warrant Shares by the Company to Broadwood (See Note 8) could result in a change of control for purposes of the severance compensation agreements, each of the executives who are parties to those agreements has waived their rights to receive payments under those agreements in the event that a change of control occurs as a result of the sale of shares and the issuance of Warrants and Additional Warrants to Broadwood. Additionally, as a result of the Company’s sale of the 6,250,000 shares of common stock to Elkhorn during the first quarter of fiscal 2014 (see Note 8), Elkhorn’s beneficial ownership of the Company has increased from approximately 9% to approximately 49% of the Company’s outstanding voting stock, making Elkhorn the Company’s largest shareholder and resulting in a change of control of for purposes of the severance compensation agreements. Each of the executives who are parties to those agreements has waived their rights to receive payments under those agreements as a result of the change in Elkhorn’s beneficial ownership of the Company. Letter of Credit During the first quarter of fiscal 2010, the Company obtained a $77,000 letter of credit from Silicon Valley Bank (“SVB”) to allow for continuous and unlapsed compliance with a lease provision for the Company’s corporate offices. The letter of credit expires on August 1, 2014. Legal Contingencies On April 26, 2011, Chicony, the contract manufacturer of the Bronx product that was the subject of a product recall, filed a complaint against us for breach of contract, seeking payment of $1.2 million for the alleged non-payment by us of amounts alleged by Chicony to be due it for products purchased from it by the Company. We denied liability and filed a cross-complaint on May 13, 2011 seeking the recovery of damages of $4.9 million caused by Chicony's failure to adhere to our technical specifications when manufacturing the Bronx product, which we believe resulted in the recall of the product. On April 16, 2013, the court approved our first-amended cross-complaint, which adds intentional interference to our complaint and increases the damages we seek to at least $15.0 million. The trial date is currently set for October, 2013. In an effort to resolve this litigation before the previous trial date of April, 2013, we sent Chicony a settlement offer, which has since lapsed. During the fourth quarter of fiscal 2013, we received reimbursement of previously incurred legal fees in the amount of $0.4 million from our insurance carrier under a reservation of rights. The outcome of this matter is not determinable as of the date of the filing of this report. We have previously accrued $1.1 million for the possibility that we could incur a liability to Chicony should it prevail in the lawsuit. On September 1, 2011, subsequent to receiving an infringement notification from us, ACCO Brands USA LLC and its Kensington Computer Products Group division (collectively “Kensington”) filed a lawsuit against us alleging that five of our patents relating to power technology are invalid and/or not infringed by products made and/or sold by Kensington. On February 29, 2012, we denied these claims and filed a cross-complaint alleging infringement by Kensington of each of these five patents. Efforts to resolve the dispute, by court ordered mediation, have been unsuccessful. Currently, the trial date is set for January, 2014. A number of these patents are currently the subject of re-examination proceedings initiated by Kensington or other third parties. This matter is ongoing and the outcome is not determinable, however if we do not prevail we will likely not obtain a license agreement to earn future license revenue from products sold by Kensington. Conversely, should we prevail the Company may be awarded a royalty which would generate license revenue to the Company in the future. In addition to the pending matters described above, we are, from time to time, involved in various legal proceedings incidental to the conduct of our business. We are unable to predict the ultimate outcome of these matters.
