• AJAX: A NEW TWIST ON EXISTING TECHNOLOGIES

      Gilorma, Mike; Apogee Labs, Inc. (International Foundation for Telemetering, 2007-10)
      Asynchronous JavaScript and XML (AJAX) has improved web applications in a way that has enhanced performance and made the user experience more like that of a desktop application. As the performance of PCs increases and broadband Internet access is more prevalent, switching between web pages is less painful than ever. One of the biggest advantages of AJAX is the ability for a web application to update only a small piece of data without refreshing the whole page. AJAX also allows for piecewise validation of user entry as opposed to the standard form entry with which we have become so accustomed. This paper describes how AJAX enabled applications are different from classic web applications and shows the advantages and disadvantages from both client and server sides of an AJAX enabled application. AJAX is not a new technology, but rather a new approach to web applications that uses standards already in place for XHTML, CSS, DOM, XML, and JavaScript. It is this new approach that eliminates the full page refresh that was so commonplace and now gives web applications the ability to look and feel more like desktop applications.
    • A FLEXIBLE SWITCHING ARCHITECTURE FOR DIVERSE SIGNAL TYPES

      Gery, Brian; Apogee Labs, Inc. (International Foundation for Telemetering, 2007-10)
      Modern telemetry systems often require signal switching hardware to facilitate signal routing reconfiguration between missions. As these systems have grown more complex with high signal counts and diverse signal types in the same system, the need for flexible switching hardware that can adapt to these changing requirements has emerged. A novel architecture for diverse signal switching hardware is presented that addresses the changing requirements of modern telemetry systems. While conventional commercial switching gear handles each signal type in a separate group, the proposed architecture allows digital and analog signal types to be switched, multiplexed, scaled, and combined (as the signal types allow) all within the same chassis, and between signal types.
    • Network Design Considerations in Telemetry Systems

      Grebe, Andy; Klein, Wayne; Apogee Labs, Inc. (International Foundation for Telemetering, 2007-10)
      In today’s world, computer networking has become common place both in industry as well as home, however all networks are not the same! The Telemetry world, like with many industries, has critical design considerations that need to be evaluated when you begin a new system or just adding on to a current infrastructure. This paper is intended to outline needed considerations when planning or implementing a network design in Telemetry Systems. These applications can range from sensor data transport through High Definition/High Speed Video applications.
