Accounting Policies [Abstract]
Use of Estimates, Policy [Policy Text Block]	Use of estimates The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Management bases its estimates and judgments on historical experience and various other factors that are believed to be reasonable under the circumstances. Actual results could differ from those estimates. Significant estimates include the assessment of collectability of revenue recognized, and the valuation of amounts receivable, inventory, investments, assets acquired, deferred income tax assets, goodwill and intangible assets, liabilities, and stock-based compensation. These estimates have the potential to significantly impact our consolidated financial statements, either because of the significance of the financial statement item to which they relate, or because they require judgment and estimation due to the uncertainty involved in measuring, at a specific point in time, events that are continuous in nature. The critical accounting policies used in the preparation of our audited consolidated financial statements are discussed in our Annual Report on Form 10-K for the year ended December 31, 2011. There have been no changes to these policies in the second quarter of 2012.

ASU 2011-04 results from joint efforts by the FASB and the International Accounting Standards Board (“IASB”) to develop converged guidance on how to measure fair value and what disclosures to provide about fair value measurements. Although ASU 2011-04 is largely consistent with the existing US GAAP fair value measurement principles, it expands existing disclosure requirements and makes other amendments. ASU 2011-04 is effective for interim or annual reporting periods beginning after December 15, 2011, with early adoption not permitted. The Company adopted ASU 2011-04 in the first quarter of 2012; its adoption did not have a material effect on the Company’s consolidated financial statements. In September 2011, the FASB issued Accounting Standards Update 2011-08, Testing Goodwill for Impairment (“ASU 2011-08”). ASU 2011-08 amends the goodwill impairment testing guidance in ASC 350-20, by providing the option to perform a qualitative assessment before calculating the fair value of the reporting unit (i.e.: before performing Step 1 of the goodwill impairment test). If it is determined, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, the existing two-step impairment test would be required. If it is determined that the fair value more likely than not exceeds the carrying value, further testing would not be required. ASU 2011-08 does not change the calculation of goodwill or its assignment to reporting units. It also does not change the requirement to test goodwill annually for impairment, or to test for impairment between annual tests if warranted by events or circumstances. However, it does revise the examples of events and circumstances that should be considered. ASU 2011-08 is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, with early adoption permitted. The Company adopted ASU 2011-08 in the fourth quarter of 2011. In December 2011, the FASB issued Accounting Standards Update 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05 (“ASU 2011-12”). ASU 2011-12 defers certain provisions of ASU 2011-05 that relate to the presentation of reclassification adjustments out of accumulated OCI. Both ASU 2011-05 and 2011-12 are effective for interim or annual reporting periods beginning after December 15, 2011, with early adoption permitted. The guidance must be applied retrospectively for all periods presented in the financial statements. The Company adopted ASU 2011-05 and ASU 2011-12 in the first quarter of 2012. However, because the Company has no OCI in any of the periods presented, the adoptions had no effect on the Company’s consolidated financial statements. The FASB, the Emerging Issues Task Force and the SEC have issued other accounting pronouncements and regulations during 2011 and 2012 that will become effective in subsequent periods. The Company’s management does not believe that these pronouncements will have a significant impact on the Company’s consolidated financial statements at the time they become effective.

Use of Estimates, Policy [Policy Text Block]

Use of estimates

The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Management bases its estimates and judgments on historical experience and various other factors that are believed to be reasonable under the circumstances. Actual results could differ from those estimates.

Significant estimates include the assessment of collectability of revenue recognized, and the valuation of amounts receivable, inventory, investments, assets acquired, deferred income tax assets, goodwill and intangible assets, liabilities, and stock-based compensation. These estimates have the potential to significantly impact our consolidated financial statements, either because of the significance of the financial statement item to which they relate, or because they require judgment and estimation due to the uncertainty involved in measuring, at a specific point in time, events that are continuous in nature.

The critical accounting policies used in the preparation of our audited consolidated financial statements are discussed in our Annual Report on Form 10-K for the year ended December 31, 2011. There have been no changes to these policies in the second quarter of 2012.
