Accounting Policies [Abstract]
Accounting Policies	Accounting Policies Principles of Consolidation: The consolidated financial statements include the accounts of the company and its wholly owned subsidiaries and include all adjustments, which were of a normal recurring nature, necessary to present fairly the financial position of the company as of September 30, 2017 and the results of its operations and changes in its cash flow for the nine months ended September 30, 2017 and 2016, respectively. Certain foreign subsidiaries, represented by the European segment, are consolidated using an August 31 quarter end to meet filing deadlines. No material subsequent events have occurred related to the European segment, which would require disclosure or adjustment to the company's financial statements. All significant intercompany transactions are eliminated. The results of operations for the three and nine months ended September 30, 2017 are not necessarily indicative of the results to be expected for the full year. Use of Estimates: The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from these estimates. Recent Accounting Pronouncements (Already Adopted): In March 2016, the FASB issued ASU 2016-09, "Compensation – Stock Compensation: Topic 718: Improvements to Employee Share-Based Payment Accounting." ASU 2016-09 is intended to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The company adopted ASU 2016-09, effective January 1, 2017, which did not have a material impact on the company's financial statements. In July 2015, the FASB issued ASU 2015-11, “Inventory (Topic 330): Simplifying the Measurement of Inventory,” to simplify the subsequent measurement of inventory. With effectiveness of this update, entities are required to subsequently measure inventory at the lower of cost or net realizable value rather than at the lower of cost or market. The company adopted ASU 2015-11, effective January 1, 2017, which did not have a material impact on the company's financial statements. Recent Accounting Pronouncements (Not Yet Adopted): In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers." ASU 2014-09 requires a company to recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The guidance requires five steps to be applied: 1) identify the contract(s) with customers, 2) identify the performance obligations in the contract, 3) determine the transaction price, 4) allocate the transaction price to the performance obligation in the contract and 5) recognize revenue when (or as) the entity satisfies a performance obligation. The guidance also requires both quantitative and qualitative disclosures, which are more comprehensive than existing revenue standards. The disclosures are intended to enable financial statement users to understand the nature, timing and uncertainty of revenue and the related cash flow. An entity can apply the new revenue standard retrospectively to each prior reporting period presented or retrospective with the cumulative effect of initially applying the standard recognized at the date of initial application in retained earnings. The new accounting guidance is effective for annual periods beginning after December 15, 2017, due to an approved one-year deferral, and early adoption is permitted. During 2017, the company completed an assessment of its contracts and related accounting. The Company concluded it has a product revenue stream for which revenue is recognized at a point in time and a service revenue stream for which revenue is principally recognized at a point in time with some service revenues recognized over time. Based on this review, the company does not expect this standard will have a material impact on the company's results of operations or cash flows in the periods after adoption. Pursuant to ASU 2014-09, revenues are recognized as control transfers to the customers, which is consistent with the current revenue recognition model and the current accounting for most of the company's contracts. The company expects to adopt the provisions of ASU 2014-09 on a modified retrospective basis through a cumulative effect adjustment to equity. The company will continue to evaluate the impact of ASU 2014-09, as well as any subsequent updates and clarifications, and the possible impact of the standard on any new contracts entered into by the company through the date of adoption. In February 2016, the FASB issued ASU 2016-02, "Leases." ASU 2016-02 requires lessees to put most leases on their balance sheet while recognizing expense in a manner similar to existing accounting. The new accounting guidance is effective for fiscal periods beginning after December 15, 2018 and early adoption is permitted. The company is currently reviewing the impact of the adoption of ASU 2016-02 on the company's financial statements. In June 2016, the FASB issued ASU 2016-13, "Measurement of Credit Losses on Financial Statements." ASU 2016-13 requires a new credit loss standard for most financial assets and certain other instruments. For example, entities will be required to use an "expected loss" model that will generally require earlier recognition of allowances for losses for trade receivables. The standard also requires additional disclosures, including disclosures regarding how an entity tracks credit quality. The amendments in the pronouncement are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Entities may early adopt the amendments as of fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The company is currently reviewing the impact of the adoption of ASU 2016-09 on the company's financial statements. In January 2017, the FASB issued ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment". The guidance in ASU 2017-04 eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under the amendments in the new ASU, goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The new standard is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis. Early adoption is permitted for annual or interim goodwill impairment testing performed after January 1, 2017. The company is currently reviewing the impact of the adoption of ASU 2017-04 but does not expect the adoption to impact the company's financial statements. Reclassifications: In 2016, the company redefined the measure by which it evaluates segment profit or loss to be segment operating profit (loss). The previous performance measure was earnings before income taxes. All prior periods presented were changed to reflect the new measure. During the first quarter of 2017, a subsidiary, formerly included in the Europe segment, transferred to the NA/HME segment as it is managed by the NA/HME segment manager effective January 1, 2017. The results for 2016 have been changed accordingly and for the three and nine months ended September 30, 2016, the change increased revenues from external customers by $1,300,000 and $3,738,000, respectively, and operating loss by $15,000 and $165,000, respectively, for NA/HME with an offsetting impact for Europe.

Accounting Policies

Principles of Consolidation:

The consolidated financial statements include the accounts of the company and its wholly owned subsidiaries and include all adjustments, which were of a normal recurring nature, necessary to present fairly the financial position of the company as of September 30, 2017 and the results of its operations and changes in its cash flow for the nine months ended September 30, 2017 and 2016, respectively. Certain foreign subsidiaries, represented by the European segment, are consolidated using an August 31 quarter end to meet filing deadlines. No material subsequent events have occurred related to the European segment, which would require disclosure or adjustment to the company's financial statements. All significant intercompany transactions are eliminated. The results of operations for the three and nine months ended September 30, 2017 are not necessarily indicative of the results to be expected for the full year.

Use of Estimates:

The consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States, which require management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from these estimates.
