Credit Facilities [Abstract]
Credit Facility [Text Block]	Credit Facility In November 2010, we entered into a Credit and Security Agreement (credit facility) with Wells Fargo Bank (Wells Fargo). The credit facility provides us with a revolving credit of up to $35 million through November 2013 that can be used for working capital requirements, letters of credit, and other general corporate purposes. The credit facility was initially secured by the Company's accounts receivables and inventory assets and was subject to a borrowing base formula based on the Company's eligible accounts receivable and inventory accounts. On December 21, 2011, we signed an amendment to our credit facility that increased our eligible borrowing base by up to $10 million by adding to the borrowing base formula 85% of the appraised value of the Company's equipment and 50% of the appraised value of the Company's real estate. In addition, Wells Fargo reduced our restrictions under the excess availability financial covenant requirement from $7.5 million to $3.5 million through December 2012. The interest rate on outstanding borrowings was increased to LIBOR rate plus four percent. We now expect at least 70% of the total amount of credit under the credit facility to be available for use based on the revised borrowing base formula during fiscal 2012. The credit facility will return to its previous agreement terms on the earlier of (i) December 31, 2012, or (ii) the date that we receive insurance proceeds of not less than $30.0 million in the aggregate applicable to the flooding of our primary contract manufacturer in Thailand. See Footnote 9 - Flood-related Losses for additional disclosures related to the impact of the Thailand flood on our operations. Our credit facility contains customary representations and warranties, and affirmative and negative covenants, including, among other things, cash balance and excess availability requirements, minimum tangible net worth and EBITDA covenants and limitations on liens and certain additional indebtedness and guarantees. The covenants are written such that as long as we maintain the minimum cash balance and excess availability requirement of $7.5 million prior to the amendment, and $3.5 million following the amendment, the other covenants are not required to be met. As of December 31, 2011, we were in compliance with the financial covenants contained in the credit facility. Our credit facility also contains certain events of default, including a subjective acceleration clause. Under this clause, Wells Fargo may declare an event of default if it believes in good faith that our ability to pay all or any portion of its indebtedness with Wells Fargo or to perform any of its material obligations under the credit facility has been impaired, or if it believes in good faith that there has been a material adverse change in the business or financial condition of the Company. If an event of default is not cured within the grace period (if applicable), then Wells Fargo may, among other things, accelerate repayment of amounts borrowed under the credit facility, cease making advances under the credit facility or take possession of the Company's assets that secure its obligations under the credit facility. We do not anticipate at this time any change in the business or financial condition of the Company that could be deemed a material adverse change by Wells Fargo. Wells Fargo has confirmed that they do not consider the flooding at our contract manufacturer's facility to be a material adverse change in the business or financial condition of the Company. As of December 31, 2011, we had a $6.0 million LIBOR rate loan outstanding, with an interest rate of 3.625%, and approximately $2.6 million reserved for eight outstanding stand-by letters of credit under the credit facility. We paid off the outstanding loan with cash on hand on January 6, 2012.
