Foreign Currency Transactions and Translations Policy [Policy Text Block]	Translation adjustment Management has determined that the local currency of our German, Canadian, and Brazilian subsidiaries is the functional currency, and accordingly, European euro, Canadian dollar, and Brazilian real denominated balance sheet accounts are translated into U.S. dollars at the rate of exchange in effect at the balance sheet date. Income and expense activity for the period is translated at the weighted average exchange rate during the period. Translation adjustments are included as a separate component of stockholders' equity.
Use of Estimates, Policy [Policy Text Block]	Use of estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from the estimates and assumptions used. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available to management. Areas in which the nature of the estimate makes it reasonably possible that actual results could materially differ from amounts estimated include: impairment assessments on long-lived assets, allowance for doubtful accounts, inventory reserves, income tax assets and liabilities and contingent liabilities.
