Debt Disclosure [Abstract]
Debt	DEBT Credit facilities On December 22, 2011, we entered into a $4.5 million revolving line of credit (“credit facility”) with Rosenthal & Rosenthal. The total loan amount available to us under the line of credit was equal to 85 percent of our net, eligible receivables, plus available inventory (50 percent of the lower of cost or market value of eligible inventory, or $250 thousand, whichever was less). The credit facility was secured by a lien on our domestic assets. The interest rate for borrowing on accounts receivable was 8.5 percent, on inventories 10 percent, and on overdrafts 13 percent. Additionally, there was an annual 1 percent facility fee on the entire $4.5 million amount of the credit facility payable at the beginning of the year. The agreement automatically renewed from year to year after December 31, 2014, unless we provided the requisite notice to Rosenthal. Additionally, Rosenthal had the right to terminate the agreement by providing 60 days written notice to us. We provided the required advance notice to Rosenthal, and as such, the facility was terminated in December 2015. Borrowings On June 1, 2009, we entered into a $70 thousand unsecured promissory note with Quercus Trust that bore interest in the amount of 1 percent per year. The principal and accrued interest on the note were due on June 1, 2109. In December 2015, we entered into an agreement with Quercus Trust to cancel the note and the accrued interest for a single payment of $13 thousand in cash. At the time of the cancellation, we had recorded $5 thousand in accrued interest on this note. For the year ended December 31, 2015, we recognized a gain of $62 thousand within “Other income” within the Consolidated Statements of Operations as a result of this cancellation.
