Summary of Significant Accounting Policies (Policies)	9 Months Ended

Use of estimates [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 accounts receivable, inventory, investments, goodwill and intangible assets, liabilities, contingent consideration, deferred income tax assets and 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 functional currency of foreign operations is deemed to be the local country’s currency. Assets and liabilities of operations outside of the United States are generally translated into U.S. dollars, and the effects of foreign currency translation adjustments are included as a component of accumulated other comprehensive income (loss). 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, 2014. There have been no changes to these policies in the first nine months of 2015.
Recently Adopted Accounting Pronouncements [Policy Text Block]	Recently Adopted Accounting Pronouncements In April 2014, the FASB issued Accounting Standards Update 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity (“ASU 2014-08”). ASU 2014-08 requires discontinued operations treatment for disposals of a component or group of components that represents a strategic shift that has or will have a major impact on an entity’s operations or financial results. It also expands the scope of ASC 205-20 to disposals of equity method investments and acquired businesses held for sale. With respect to disclosures, ASU 2014-08 both 1) expands disclosure requirements for transactions that meet the definition of a discontinued operation, and 2) requires entities to disclose information about individually significant components that are disposed of or held for sale and do not qualify as discontinued operations. ASU 2014-08 also requires specific presentation of various items on the face of the financial statements. ASU 2014-08 is effective for interim and annual periods beginning on or after December 15, 2014, with early adoption permitted. The Company therefore adopted ASU 2014-08 in the first quarter of 2015. However, since the Company does not currently have either discontinued operations or any planned disposals that would require the expanded reporting required by ASU 2014-08, its adoption had no impact on its consolidated financial statements.
Future Accounting Pronouncements [Policy Text Block]	Future Accounting Pronouncements In January 2015, the FASB issued Accounting Standards update 2015-01, Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items (“ASU 2015-01”). ASU 2015-01 eliminates the requirement for entities to consider whether an underlying event or transaction is extraordinary, and, if so, to separately present the item in the income statement net of tax, after income from continuing operations. Instead, items that are both unusual and infrequent should be separately presented as a component of income from continuing operations, or be disclosed in the notes to the financial statements. ASU 2015-01 will be effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 31, 2015. Early adoption is permitted provided that the new standard is applied from the beginning of the fiscal year of adoption. The Company has not historically reported extraordinary items in its consolidated financial statements, and is not aware of any pending transactions or events that might have required reporting as extraordinary items, and therefore does not expect the adoption of ASU 2015-01 to have a material impact on its consolidated financial statements. In March 2015, the FASB issued Accounting Standards update 2015-02, Amendments to the Consolidation Analysis (“ASU 2015-02”). ASU 2015-02 eliminates entity specific consolidation guidance for limited partnerships, and revises other aspects of the consolidation analysis, but does not change the existing consolidation guidance for corporations that are not variable interest entities (“VIEs”). For public business entities, ASU 2015-02 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company has not yet adopted ASU 2015-02 nor assessed its potential impact on its consolidated financial statements. In April 2015, the FASB issued Accounting Standards update 2015-03, Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). ASU 2015-03 changes the presentation of debt issuance costs in financial statements, by requiring them to be presented in the balance sheet as a direct deduction from the related debt liability, rather than as an asset. Amortization of the costs is reported as interest expense. There is no change to the current guidance on the recognition and measurement of debt issuance costs. For public business entities, ASU 2015-03 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, with early adoption permitted. The Company has not yet adopted ASU 2015-03 nor assessed its potential impact on its consolidated financial statements. In August 2015, the FASB issued Accounting Standards update 2015-15, Interest – Imputation of Interest , (“ASU 2015-15”). ASU 2015-15 amends subtopic 835-30 of the accounting standards codification (which was previously amended by ASU 2015-03), to allow for the capitalization of debt issuance costs related to line of credit agreements. Capitalized costs would be presented as an asset and subsequently amortized ratably over the term of the line of credit. The Company has not yet adopted ASU 2015-15 nor assessed its potential impact on its consolidated financial statements. In September 2015, the FASB issued Accounting Standards update 2015-16, Simplifying the Accounting for Measurement-Period Adjustments (“ASU 2015-16”). ASU 2015-16 changes the recognition of business combination adjustments by requiring acquirers to recognize adjustments to provisional amounts identified during the measurement period in the reporting period in which the adjustment amounts are determined. The acquirer is required to record the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts. These amounts are calculated as if the accounting was completed at acquisition date. The acquirer is also required to present separately on the face of the income statement, or disclose in the notes, the amount recorded in current-period earnings (by line item) that would have been recorded in previous reporting periods had the adjustments been recognized as of the acquisition date. ASU 2015-16 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The Company has not yet adopted ASU 2015-16 nor assessed its potential impact on its consolidated financial statements.
