|Basis of Accounting, Policy [Policy Text Block]                                                                                               | GeneralThe consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany amounts have been eliminated. The results of operations include the operating results of Hego since the completion of the Business Combination on May 22, 2013. See Note 8 of these consolidated financial statements.In the opinion of management of the Company, the unaudited consolidated interim financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position of the Company as of March 31, 2014 and the consolidated results of its operations, its comprehensive income (loss) and its cash flows for the periods ended March 31, 2014 and 2013. The results of operations for such interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the year ending December 31, 2014. In addition, management is required to make estimates and assumptions that affect the amounts reported and related disclosures. Estimates made by management include inventory valuations, stock and bonus compensation, allowances for doubtful accounts, income taxes, pension assumptions, allocations of purchase price, contingent
      consideration, valuation of intangible assets and reserves for warranty and incurred but not reported health insurance claims. Estimates, by their nature, are based on judgment and available information. Also, during interim periods, certain costs and expenses are allocated among periods based on an estimate of time expired, benefit received, or other activity associated with the periods. Accordingly, actual results could differ from those estimates. The Company has not segregated its cost of sales between costs of products and costs of services as it is not practicable to segregate such costs. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to the rules and regulations of the Securities and Exchange Commission. For further information, refer to the audited consolidated financial statements and footnotes thereto included in the Company's Annual
      Report on Form 10-K for the year ended December 31, 2013. The December 31, 2013 figures included herein were derived from such audited consolidated financial statements.
|New Accounting Pronouncements, Policy [Policy Text Block]                                                                                     | Recent Accounting PronouncementsIn April 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-08, which includes amendments that change the requirements for reporting discontinued operations and requires additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations should be presented as discontinued operations. Additionally, the ASU requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. This update is effective for periods beginning after December 15, 2014. The implementation of the amended guidance is not expected to have a material impact on the Company's consolidated financial statements.In July 2013, the FASB issued ASU 2013-11, which provides that an unrecognized tax benefit, or a portion thereof, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except to the extent that a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date to settle any additional income taxes that would result from disallowance of a tax position, or the tax law does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, in which case the unrecognized tax benefit should be presented as a liability. This standard is effective for fiscal years beginning after December 15, 2013. The Company's adoption of this standard did not have a significant impact on its
      consolidated financial statements.In March 2013, the FASB issued ASU 2013-05, which addresses the accounting for a cumulative translation adjustment when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity. The standard is effective for fiscal years beginning after December 15, 2013. The Company's adoption of this standard did not have a significant impact on its consolidated financial statements.                                                                                           
|Earnings Per Share, Policy [Policy Text Block]                                                                                                | Earnings (Loss) Per ShareBasic earnings (loss) per share is computed by dividing net income (loss) by the weighted average number of shares of common stock outstanding. Diluted earnings (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding during the period, increased to include the number of shares of common stock that would have been outstanding had potential dilutive shares of common stock been issued. The dilutive effect of stock options and restricted stock units are reflected in diluted net income (loss) per share by applying the treasury stock method.The Company recorded net losses for the three months ended March 31, 2014 and 2013. Potential common shares are anti-dilutive in periods in which the Company records a net loss because they would reduce the respective period's net loss per share. Anti-dilutive potential common shares are excluded from the calculation of diluted earnings per share. As a result, net diluted loss per share was equal to basic net loss per share in all periods presented.Shares excluded from the calculation are as follows (in thousands):Three MonthsEnded March 31,2014
