Warrant Liabilities [Abstract]
Warrant Liabilities [Text Block]	Note 7 – Warrant Liabilities As part of the Company’s restructuring plan, see Note 3 – Plan of Restructuring, the Company issued 166,600 one-year warrants (the “A Warrants”). The expiration date of the A Warrants was subsequently extended until September 13, 2013, at which time 161,200 unexercised A Warrants expired. Each A Warrant entitled the holder to purchase one share of the Company’s Common Stock and a three-year warrant (the “B Warrants”), at an exercise price of $5.00 per share. 5,400 A Warrants were exercised before the expiration, resulting in the issuance of 5,400 B Warrants. As a result of the Retop investment (see Note 10 – Securities Purchase Agreement for Common Stock) and the repricing clause in the B Warrant agreement, there are now 11,250 B Warrants that each entitle the holder to purchase one share of the Company’s Common Stock at an exercise price of $6.00 per share, which expire on November 11, 2014. In connection with the Offering, the Company issued 48,000 three-year warrants to the Placement Agent (the “Placement Agent Warrants”). As a result of the Retop investment (see Note 10 – Securities Purchase Agreement for Common Stock) and the repricing clause in the Placement Agent Warrant agreement, there are now 100,000 Placement Agent Warrants exercisable at a price of $6.00 per share. Upon the exercise of these Placement Agent Warrants, the Company will issue 9,600 A Warrants to the Placement Agent and upon the exercise of these A Warrants, the Company will issue 9,600 B Warrants to the Placement Agent. The aggregate number of Placement Agent Warrants, A Warrants and B Warrants to which the Placement Agent is entitled is 119,200. Each Placement Agent Warrant entitles the Placement Agent to purchase one share of the Company’s Common Stock at an exercise price of $6.00 per share and a two-year A Warrant. Each A Warrant, which would expire on November 14, 2016, would entitle the Placement Agent to purchase one share of the Company’s Common Stock and a three-year B Warrant at an exercise price of $5.00 per share. Each B Warrant, which would expire on November 14, 2017, shall entitle the Placement Agent to purchase one share of the Company’s Common Stock at an exercise price of $12.50 per share. In connection with a private placement of $650,000 of 4.00% notes, see Note 8 – Long-Term Debt, the Company issued 40,000 warrants to the subscriber at an exercise price of $2.50 per share, which expire on June 17, 2016. The foregoing warrants include a potential adjustment of the strike price if the Company sells or grants any option or warrant at a price per share less than the strike price of the warrants. Therefore, these warrants are not considered indexed to the Company’s Common Stock and are accounted for on a liability basis. The Company recorded non-cash expenses of $423,000 and $376,000 in the three and six months ended June 30, 2014, respectively, and non-cash gains of $732,000 and $664,000 in the three and six months ended June 30, 2013, respectively, related to changes in the value of the warrants issued in the Offering, the Placement Agent and the subscriber in connection with the $650,000 of 4.00% secured notes, which is included in Change in warrant liabilities and other warrant expense in the Condensed Consolidated Statements of Operations. On June 11, 2013, the Company entered into a Master Agreement for Sale and Assignment of Leases with AXIS Capital, Inc. (the “Assignment Agreement”) and financed the future receivables relating to certain lease contracts. In connection with the Assignment Agreement, the Company issued warrants to purchase 7,200 shares of the Company’s Common Stock, par value $0.001, to AXIS Capital, Inc. at an exercise price of $12.50 per share. These warrants did not include a potential adjustment of the strike price if the Company sells or grants any options or warrants at a price per share less than the strike price of the warrants, so they were considered indexed to the Company’s Common Stock and were accounted for as equity. These warrants expired unexercised on June 11, 2014. In November 2012, the Board of Directors approved the issuance to two board members, George W. Schiele and Salvatore J. Zizza, of warrants to purchase 20,000 shares of Common Stock at an exercise price of $12.50 per share.

The warrants were issued effective October 2, 2013 and begin to vest after one year. The Company recorded non-cash expenses of $21,000 and $42,000 in the three and six months ended June 30, 2014, respectively, related to the value of the warrants issued, which is included in Change in warrant liabilities and other warrant expense in the Condensed Consolidated Statements of Operations. These warrants do not include a potential adjustment of the strike price if the Company sells or grants any options or warrants at a price per share less than the strike price of the warrants, so they are considered indexed to the Company’s Common Stock and were accounted for as equity. On June 27, 2014, the Company entered into a Securities Purchase Agreement (the “SPA”) with Retop Industrial (Hong Kong) Limited (“Retop”), pursuant to which Retop purchased 333,333 shares of the Company’s Common Stock, par value $0.001 per share, for a purchase price of $2,000,000 (the “Purchase”).
