Debt Disclosure [Text Block]	4. CREDIT FACILITY In August 2012, the Company entered into a loan modification agreement and amended its loan and security agreement (the "Credit Facility") with Silicon Valley Bank 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 can be used to purchase equipment in an aggregate amount of up to $1.0 million (the "Term Loan"). Advances on the Revolving Line are limited to 80% of eligible accounts receivable. At September 30, 2012 available borrowings were approximately $2.1 million and no borrowings were outstanding. The Revolving Line continues to bear interest at a floating annual rate equal to Silicon Valley Bank's prime rate ("Prime") +1.75%. Advances under the Term Loan may be drawn until December 31, 2012 in minimum amounts of $0.25 million. The Term Loan bears interest at Prime +2.25% and principal and interest will be repaid over thirty months. At September 30, 2012, no amounts were outstanding; however, on October 17, 2012, the Company took an advance of $0.35 million on the Term Loan. The 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. The Company is required to maintain financial covenants based on an adjusted quick ratio 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 the Company from any sale of its equity or incurrence of subordinated debt and any positive quarterly net income earned, measured at quarter end (both as defined as per the Credit Facility). 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. The Company has been in compliance with all debt covenants since inception of the Credit Facility. 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 September 30, 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 2009 Term Loan was $1 thousand and $15 thousand for the nine months ended September 30, 2012 and 2011, respectively. Interest expense related to the 2009 Term Loan was $0 and $4 thousand for the three months ended September 30, 2012 and 2011, respectively.
