| Subsequent Events [Text Block] | Note 11. Subsequent Events In January, 2014, we closed on a registered direct offering providing for $20 million of gross proceeds from the sale of 6,872,859 shares of our common stock and 3,436,435 common stock purchase warrants. This offering was pursuant to our $50 million shelf registration statement declared effective by the SEC on September 13, 2013. Additionally, as a result of this transaction an advisor to the Company met certain capital raising milestones and consequently, the term of their common stock purchase warrant was extended to 5 years. |
