Goodwill and Intangible Assets Disclosure [Text Block] | The Company’s goodwill represents the excess of the purchase price over the fair value of net identifiable assets acquired in the August 29, 2014 IQinVision business combination. Goodwill is not amortized and is tested for impairment on an annual basis during the Company's fourth quarter, or more frequently if circumstances indicate impairment might exist. Goodwill is evaluated for impairment through the comparison of fair value of reporting units to their carrying values. When evaluating goodwill for impairment, the Company may first perform an assessment of qualitative factors to determine if the fair value of the reporting unit is more-likely-than-not greater than its carrying amount. This qualitative assessment is referred to as a "step zero" approach. If, based on the review of the qualitative factors, the Company determines it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying value, the required two-step impairment test can be bypassed. If the Company does not perform a qualitative assessment or if the fair value of the reporting unit is not more-likely-than-not greater than its carrying value, the Company must perform the first step of the two-step impairment test, and calculate the estimated fair value of the reporting unit. If the carrying value of the reporting unit exceeds the estimated fair value, there is an indication that impairment may exist and the second step must be performed to measure the amount of impairment. The amount of impairment is determined by comparing the implied fair value of the reporting unit goodwill to the carrying value of the goodwill in the same manner as if the reporting unit was being acquired in a business combination. If the implied fair value of goodwill is less than the recorded goodwill, an impairment loss for the difference would be recorded. In considering the step zero approach to testing goodwill for impairment, a qualitative analysis is performed evaluating factors including, but not limited to, macro-economic conditions, market and industry conditions, internal cost factors, competitive environment, share price fluctuations, results of past impairment tests, and the operational stability and the overall financial performance of the reporting units. The Company conducted an impairment test at March 31, 2016 using the income approach and determined that its goodwill carrying value was fully impaired. As a result, the Company recorded an impairment charge of $6.0 million in the quarter ended March 31, 2016. This noncash charge was principally based upon an updated assessment of the Company's continuing depressed market valuation and operating losses. The components and estimated useful lives of intangible assets as of March 31, 2016 and September 30, 2015 are stated below. Amortization is provided on a straight line method, or in the case of customer relationships, on an accelerated method, over the following estimated useful lives: March 31, 2016 September 30, 2015 Gross Amount Accumulated Amortization Gross Amount Accumulated Amortization Estimated Useful Life Definite-lived intangibles: Technology $ 2,500,000 $ 395,833 $ 2,500,000 $ 270,833 10 years Customer relationships 910,000 260,333 910,000 148,833 7 years Tradenames 660,000 69,667 660,000 47,667 15 years $ 4,070,000 $ 725,833 $ 4,070,000 $ 467,333 The activity in the goodwill balance consists of the following: Balance at October 1, 2013 $ — Acquisition of IQinVision 6,016,469 Balance at September 30, 2014 6,016,469 Changes in Goodwill — Balance at September 30, 2015 6,016,469 Goodwill impairment (6,016,469 ) Balance at March 31, 2016 $ — Amortization expense was $129,250 and $258,500 for the three and six month periods ended March 31, 2016 .
