Contingencies	6. Contingencies On November 29, 2011, AMR Corporation, the parent company of American Airlines, Inc. (“AAI”) and certain of its other U.S. based subsidiaries filed voluntary petitions for Chapter 11 reorganization in the U.S. Bankruptcy Court for the Southern District of New York (the “Bankruptcy”). For the three and six months ended March 31, 2013, AAI accounted for 19% and 16%, respectively, of net sales. For the three and six months ended March 31, 2012, AAI accounted for 1% and 8%, respectively, of net sales. AAI continued to purchase products from the Company in the ordinary course of business after November 29, 2011. As of November 29, 2011, the Company had pre-Bankruptcy outstanding accounts receivable of $760,000 from AAI. The Company believes it is probable that the outstanding receivables will be collected in full and, therefore, no reserve has been recorded against these assets as of the balance sheet date. In the 90 days preceding the filing of the Bankruptcy petition, the Company received $828,000 from AAI in the ordinary course of business. Under the U.S. bankruptcy laws, debtors have the right to avoid certain payments made during the 90 days preceding the filing of the bankruptcy petition. No such avoidance action has been asserted or filed, and the Company believes that it would have valid defenses against any such action. On September 26, 2011, Farhad Daghigh, a former employee of the Company, filed a lawsuit against the Company in the Court of Common Pleas of Chester County alleging breach of contract and violation of the Pennsylvania Wage Payment and Collection Law claiming unpaid sales commissions, prejudgment interest, and liquidated damages totaling approximately $583,000 for the fiscal years ended 2007, 2008, 2009 and 2010. The Company vehemently denies any allegations of liability and will vigorously defend the lawsuit. This matter has not been resolved as of the date hereof. The Company believes that the probability of an unfavorable outcome on this claim is remote, and, therefore, no contingent liability has been recorded at March 31, 2013. On January 17, 2007 the Company filed suit in the Court of Common Pleas for Delaware County, Pennsylvania against Strathman Associates, a former software consultant for IS&S, alleging that Strathman had improperly used IS&S trade secret and proprietary information in assisting J2 and Kollsman in developing the J2/Kollsman Air Data Computer. This matter has not been resolved as of the date hereof.
