Subsequent Events [Text Block]	Note 10. Subsequent Event On October 7, 2013, we borrowed $1.0 million of the $3.5 million commitment under the 2013 Note. At the time of the borrowing, the 2013 Note conversion price of $0.89 was below the closing bid price of our common stock of $0.95, which resulted in a beneficial conversion feature. The beneficial conversion feature is calculated at its intrinsic value (that is, the difference between the conversion price and the fair value of the common stock into which the debt is convertible, multiplied by the number of shares into which the debt is convertible) at the date of borrowing. The beneficial conversion feature of the $1.0 million borrowing on October 7, 2013 amounted to $67 thousand, which will be recorded as a convertible debt discount with a corresponding increase to additional paid-in capital. The amount will be amortized over a five-year period from the borrowing date to the Maturity Date.

Note 10. Subsequent Event

On October 7, 2013, we borrowed $1.0 million of the $3.5 million commitment under the 2013 Note. At the time of the borrowing, the 2013 Note conversion price of $0.89 was below the closing bid price of our common stock of $0.95, which resulted in a beneficial conversion feature. The beneficial conversion feature is calculated at its intrinsic value (that is, the difference between the conversion price and the fair value of the common stock into which the debt is convertible, multiplied by the number of shares into which the debt is convertible) at the date of borrowing.

The beneficial conversion feature of the $1.0 million borrowing on October 7, 2013 amounted to $67 thousand, which will be recorded as a convertible debt discount with a corresponding increase to additional paid-in capital. The amount will be amortized over a five-year period from the borrowing date to the Maturity Date.
