Subsequent Events [Abstract]
Subsequent Events	(15) Subsequent Events On February 11, 2015, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Roth Capital Partners, LLC, as Underwriter (the “Underwriter”). The Underwriting Agreement provided for the sale to the Underwriter of 2,460,000 shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”), and warrants (the “Warrants”) to initially purchase up to an aggregate of 1,107,000 shares of the Common Stock (the “Offering”). The Offering closed on February 17, 2015. The Warrants are exercisable beginning on the date six months after the date of issuance and will expire five years from the date of issuance. The exercise price of the Warrants is $1.38 per share of Common Stock, subject to certain adjustments. The net proceeds to the Company from the offering are approximately $2.4 million after underwriting discounts and commissions and other estimated offering expenses payable by the Company, and excluding any proceeds the Company may receive upon exercise of the warrants to be issued in the Offering. As a result, the exercise price of the 2012 Warrants has been adjusted to $0.82.
