Debt Disclosure [Text Block]	7. CREDIT FACILITY In August 2012, we entered into a loan modification agreement and amended our loan and security agreement (the "Credit Facility") with Silicon Valley Bank ("SVB") to extend the term of the Credit Facility to August 12, 2013, to increase the revolving line of credit (the "Revolving Line") from $1.5 million to $3.0 million, and to add a term loan facility that could be used to purchase equipment up to $1.0 million (the "Term Loan"). At December 31, 2012, available borrowings under the Revolving Line were approximately $2.7 million but no borrowings were outstanding. Advances under the Term Loan were available to be drawn until December 31, 2012 in minimum amounts of $0.25 million. During the fourth quarter of 2012, the Company took two advances of $0.35 million each from the Term Loan and the balance outstanding at December 31, 2012 was $0.68 million. The Term Loan bears interest at Prime +2.25% (6.25% at December 31, 2012) and principal and interest are being repaid over thirty months. Pursuant to the Credit Facility, we were required to maintain financial covenants based on an adjusted quick ratio ("AQR") of at least 1.2 to 1.0, measured at each calendar month-end, and minimum tangible net worth of $18.5 million, increased by 60% of the sum of the gross proceeds received by us from any sale of our equity or incurrence of subordinated debt and any positive quarterly net income earned, measured at quarter-end (both as defined in the Credit Facility). Due to the significant charge of $19.5 million taken in the fourth quarter of 2012 to increase the valuation allowance for deferred tax assets, we failed the tangible net worth covenant at December 31, 2012, and obtained a waiver from SVB. Additionally, in March 2013 we entered into a loan modification agreement and amended our loan and security agreement (the "Revised Credit Facility") with SVB to modify a financial covenant and decrease the Revolving Line amount. The existing expiration date of the facility remained at August 12, 2013. The same as the Credit Facility, the Revolving Line bears interest at a floating annual rate equal to Silicon Valley Bank's prime rate ("Prime") +1.75%, and the AQR financial covenant remains at 1.2x. The tangible net worth covenant was replaced by a maximum EBITDA loss/profitability covenant (tested at end of each quarter) effective with the first quarter of 2013. The Revolving Line was reduced from $3 million to $2 million, and available borrowings under the Revolving Line was changed from 80% of eligible accounts receivable to 80% of eligible accounts receivable less the amount of principal outstanding under the Term Loan. Additionally, if the Company's AQR falls below 1.5x at any month-end during the remaining term of the facility, then any borrowings under the Revolving Line will be repaid by SVB applying collections from the Company's SVB collateral account (for receipts by wire) and SVB lockbox account (for receipts by check) to reduce the revolving loan balance on a daily basis, until such time as the month-end AQR is again 1.5x or greater. If the AQR at month-end is 1.5x or greater, the Company will maintain a static loan balance and all collections will be deposited into the Company's operating account. As is usual and customary in such lending agreements, the agreements also contain certain non-financial requirements, such as required periodic reporting to the bank and various representations and warranties. The lending agreement also restricts our ability to pay dividends without the bank's consent. The Credit Facility was and the Revised Credit facility is collateralized by the Company's assets, except for (i) its intellectual property rights which are subject to a negative pledge arrangement with the bank, and (ii) any equipment whose purchase is financed by any other lender or lessor, solely to the extent the security agreement with such lender or lessor prohibits junior liens on such equipment, and only until the lien held by such lender or lessor is terminated or released with respect to such equipment. As is usual and customary in such lending agreements, the agreements also contain certain nonfinancial requirements, such as required periodic reporting to the bank and various representations and warranties. The lending agreement also restricts the Company's ability to pay dividends without the bank's consent. In 2009, the Company borrowed to finance capital equipment under the then existing credit facility which resulted in a term loan (the "2009 Term Loan") of $977 thousand payable over 36 months in equal monthly installments of principal plus accrued interest. As of May 2012, the Company had repaid all principal and interest and there was no outstanding balance on the 2009 Term Loan. Interest expense related to the term loans was $7 thousand and $17 thousand for the years ended December 31, 2012 and 2011, respectively.
