Income Taxes [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes As of December 31, 2015, the Company had approximately $221.5 million of Federal net operating loss carryforwards ("NOLs") available to offset future taxable income expiring from 2025 through 2035. In accordance with Section 382 of the Internal Revenue code, the usage of the Company’s NOLs could be limited in the event of a change in ownership. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the period when those temporary differences become deductible. If a change of ownership did occur there would be an annual limitation on the usage of the Company’s losses which are available through 2035. In assessing the ability to realize deferred tax assets, including the NOLs, the Company assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to utilize its existing deferred tax assets. Based on its assessment, the Company has provided a full valuation allowance against its net deferred tax assets as the Company's ability to generate taxable income remains uncertain at this time. Deferred tax liabilities were $1.0 million and $0.9 million as of June 30, 2016 and December 31, 2015, respectively, and relate to the taxable temporary differences on the goodwill recognized in the PCT acquisition in 2011. The taxable temporary differences, which are tax deductible and will be amortized over 15 years, will continue to increase the deferred tax liability balance over the amortization period, with an associated charge to the deferred tax provision in each period. The deferred tax liability will only reverse when the indefinite-lived asset is sold, impaired, or reclassified from an indefinite-lived asset to a finite-lived asset. As of June 30, 2016, management does not believe the Company has any material uncertain tax positions that would require it to measure and reflect the potential lack of sustainability of a position on audit in its financial statements. The Company will continue to evaluate its uncertain tax positions in future periods to determine if measurement and recognition in its financial statements is necessary. The Company does not believe there will be any material changes in its unrecognized tax positions over the next year. The Company's federal tax returns are currently being audited for the years 2012 and 2013. For years prior to 2011 the federal statute of limitations is closed for assessing tax. The Company’s state tax returns remain open to examination for a period of three to four years from date of filing. The Company ceased doing business in China in 2012. After 2012, the Company had no foreign tax filing obligations. The foreign returns filed for 2012 and prior are subject to examination for five years.
