Bad debt expense was $17,256 and ($26,929) during 2014 and 2013, respectively. The credit during 2013 included a reversal of bad debt expense recorded in 2012. |

Income Tax, Policy [Policy Text Block] | L. Income Taxes - Income taxes are provided for by utilizing the asset and liability method which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities using presently enacted tax rates. Deferred tax assets are reduced by a valuation allowance which is established when “it is more likely than not” that some portion or all of the deferred tax assets will not be recognized. |
|
Use of Estimates, Policy [Policy Text Block] | M. Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Estimates are used for, but not limited to, the accounting for the allowance for doubtful accounts, inventory allowances, property and equipment depreciable lives, patents and licenses useful lives, revenue recognition, tax valuation, stock based compensation and assessing changes in which impairment of certain long-lived assets may occur. Actual results could differ from those estimates. |
