Debt Disclosure [Abstract]
Notes	(4) Notes During July 2014, we entered into a bank-issued letter of credit and related promissory note for up to $30 in borrowings to support our obligations under our facility lease agreement. No borrowings have been incurred under this promissory note. Should any borrowings occur in the future, the interest rate would be the prime rate plus 1%, with the bank having the right to “set off” or apply unpaid balances against our checking account if we fail to meet our obligations under any borrowings under the note. We have renewed this note annually and it is our intention to continue to do so for as long as we need to pursuant to the terms of our facility lease agreement. Because there were no amounts outstanding at any time during 2016 or 2015, we have recorded no related liability on our balance sheet. During March 2015, we entered into a Business Loan Agreement (the “Line of Credit Agreement”) with Libertyville Bank and Trust Company, a Wintrust Community Bank (“Libertyville”), our primary bank, which was subsequently amended on April 13, 2015. Under the Line of Credit Agreement, as amended, Libertyville will provide a maximum of $300, or 75% of our eligible accounts receivable, whichever is less, of revolving credit, collateralized by a senior priority lien on our accounts receivable, inventory, equipment, general intangibles and fixtures. Interest on any borrowings would be the prime rate at the time plus 1%. We must have at least $1 million in cash, including any amounts borrowed, at Libertyville on the date of any advance. Advances may only occur at the beginning or end of a fiscal quarter and must be repaid in full within five days of the advance. The Line of Credit Agreement was extended during March 2016, and now expires on March 4, 2017. There were two advances under this Line of Credit Agreement during 2015 that were subsequently repaid within five days of each advance, and no advances during the first six months of 2016.
