Segment Reporting Disclosure [Text Block] | 1 8 . SEGMENT INFORMATION The Company is engaged in the design, development and commercialization of directed and multidirectional sound technologies, voice broadcast products and location-based mass messaging solutions for emergency warning and workforce management. The Company operates in two business segments: Hardware and Software and its principle markets are North and South America, Europe, Middle East and Asia. As reviewed by the Company’s chief operating decision maker, the Company evaluates the performance of each segment based on sales and operating income. Cash and cash equivalents, marketable securities, accounts receivable, inventory, property and equipment, deferred tax assets, goodwill and intangible assets are primary assets identified by segment. The accounting policies for segment reporting are the same for the Company as a whole and transactions between the two operating segments are not material.
