Debt Disclosure [Text Block]	4. CREDIT FACILITY In March 2013, the Company entered into a seventh loan modification agreement and amended its loan and security agreement (the "Revised Credit Facility") with Silicon Valley Bank ("SVB"). Under this Revised Credit Facility, the expiration date of the facility remained at August 12, 2013 and the revolving line of credit (the "Revolving Line") was reduced from $3.0 million to $2.0 million. 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 that forms part of the Revised Credit Facility, as described below. The Revolving Line continues to bear interest at a floating annual rate equal to SVB's prime rate ("Prime") +1.75%. The Company also has a term loan with SVB, that was unchanged under the Revised Credit Facility, whereby advances were available to be drawn through December 31, 2012 in minimum amounts of $0.25 million. At March 31, 2013, available borrowings under the Revolving Line were approximately $1.4 million but no borrowings were outstanding. 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 March 31, 2013 was $0.6 million. The term loan bears interest at Prime +2.25% (which was 6.25% at March 31, 2013) and principal and interest are being repaid over thirty months. Interest expense related to the term loan was $10 thousand for the three months ended March 31, 2013. Pursuant to the Revised Credit Facility, the financial covenants were modified. The Company is 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 the minimum tangible net worth covenant was replaced by a maximum EBITDA loss/profitability covenant (tested at quarter end) effective with the first quarter of 2013. 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. The Company was in compliance with its financial covenants as of March 31, 2013. 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 the Company's ability to pay dividends without the bank's consent. 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.
