• Web Service Applications in Future T&E Scenarios

      Sulewski, Joe; Hamilton, John; Darr, Timothy; Fernandes, Ronald; L-3 Telemetry East; Knowledge Based Systems, Inc. (International Foundation for Telemetering, 2010-10)
      In this paper, we discuss ways in which web services can be used in future T&E scenarios, from the initial hardware setup to making dynamic configuration changes and data requests. We offer a comparison of this approach to other standards such as SNMP, FTP, and RTSP, describing the pros and cons of each as well as how these standards can be used together for certain applications.
    • A Wideband Stacked Microstrip Patch Antenna for Telemetry Applications

      Nithianandam, Jeyasingh; Hategekimana, Bayezi; Morgan State University (International Foundation for Telemetering, 2010-10)
      This research article reports a design of a wide band multilayer microstrip patch antenna (MSPA). Positions of a coaxial probe feed to main patch of the multilayer MSPA, widths and lengths of main and parasitic patches, and height of a Rohacell foam layer in the multilayer MSPA were optimized to achieve desired performance in L-band. The work also reports a design of a two-by-two array of multilayer MSPA. We present results on antenna radiation patterns and return loss obtained with full wave finite element simulations with Ansoft HFSS software and measurements with a vector network analyzer.
    • Wireless Power Transmission Using Microwave Technology

      Xin, Hao; Marcellin, Michael; Fuller, Robert; Nastase, Ryan; Elliott, Kaoru; Salhab, Anas; Campbell, Jonathan; University of Arizona (International Foundation for Telemetering, 2010-10)
      As part of the Senior Capstone class held at the University of Arizona in the College of Engineering, the team was tasked to build a prototype that could power a simple electronic device wirelessly. The team succeeded in doing so and has proven that wireless power transmission could be a valuable tool for future use. There are a few difficulties to note and specifics will be given in the body of the report.
    • Wireless Tire Temperature Sensor Patch and System for Aircraft Landing Gear Testing

      Testing aircraft brake and tire systems often results in tire temperatures that makes the aircraft unsafe to approach (due to explosion risk) for up to 45 minutes; this complicates cost effective test execution. This paper describes work on a wireless sensor system that measures multiple tire temperatures and transmits the data to someone at a safe distance (>300 ft). The solution consists of a sensor patch adhered directly to the tire which measures the tire temperature. The patch transmits these measurements to off-tire reader/relay nodes that subsequently sends the data to a system controller and display device.
    • X-Tools: A Case Study in Building World Class Software

      Cooke, Alan; ACRA Control (International Foundation for Telemetering, 2010-10)
      X-Tools is a collection of utilities for validation, translation, editing and report generation designed to enable the Flight Test Instrumentation (FTI) community to quickly adopt the XidML 3.0 meta-data standard. This paper discusses the challenges of developing such software that meets the current and future needs of the FTI community, and meets the increasingly high quality standards expected of modern software. The paper first starts by discussing the needs of the FTI community and the specific functional requirements of software. These include the ability to fit in with legacy systems, the ability to handle many tens of thousands of parameters, support for new networked-based technologies and support for hardware from any vendor. The non-functional requirements of FTI orientated software are also described and it is suggested that the key non-functional requirements include testability, modifiability, extensibility and maintainability. Finally, as a case study, the X-Tools from ACRA CONTROL are presented. The paper discusses their design, and the tactics used to meet the functional and non-functional requirements of the FTI industry. The paper then outlines how the rigorous quality standards were met and describes the specific mechanisms used to verify the quality of the software.
