Earnings Per Share [Abstract]
LOSS PER SHARE	LOSS PER SHARE Basic loss per share is computed by dividing our net loss by the weighted average number of shares outstanding during the period. Diluted loss per share is computed by dividing our net loss by the weighted average number of shares outstanding and the impact of all dilutive potential common shares, primarily stock options. The dilutive impact of common stock options and common stock warrants is determined by applying the “treasury stock” method. Potentially dilutive shares issuable pursuant to the Notes (defined in Note 6) were not included in the computation of net loss per share for the three and nine months ended September 30, 2013, because their inclusion would be anti-dilutive. Also, a total of 35,157,966 and 26,022,072 potential shares of Common Stock have been excluded from the calculation of diluted net loss per share for the three months ended September 30, 2013 and 2012, respectively, because their inclusion would be anti-dilutive. A total of 31,659,650 and 26,836,546 potential shares of Common Stock have been excluded from the calculation of net loss per share for the nine months ended September 30, 2013 and 2012, respectively, because their inclusion would be anti-dilutive. During the three months ended September 30, 2013, 3,206,230 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised and issued. During the three months ended September 30, 2012, 161,264 Common Stock options and Common Stock warrants to purchase shares of our Common Stock were exercised, resulting in the issuance of 160,411 shares of Common Stock. Of the 161,264 Common Stock options and Common Stock warrants exercised, 853 shares of Common Stock were surrendered in lieu of a cash payment via the net exercise feature of the warrant agreements.
