    Hybrid systems utilizing a zinc-air battery or a Proton Exchange Membrane Fuel Cell (PEMFC) as the high energy density component coupled with a rechargeable battery (lead-acid or nickel-metal hydride) or electrochemical capacitor (EC) bank as the high power density component were tested under a high-pulse application load, Land Warrior (LW). The hybrid power sources successfully operated the LW cyclic load beyond the capabilities of the specific single chemistry systems studied. The zinc-air battery hybrids allowed approximately triple the operation time of PEMFC hybrids. The best performing hybrid system was the zinc-air battery/lead-acid battery. It provided the greatest operating voltage and longest operating time View full abstract»

  • Achieving cost effective support solutions for the new millenium through the DoD automatic test systems selection process

    DoD policy is to minimize unique types of Automatic Test Systems (ATS) being introduced into the DoD inventory by using designated DoD families and by encouraging the use of commercial testers that meet defined hardware and software interfaces. This policy has been incorporated into DoD 5000 2-R of 15 March 1996 (with Change 3 of 23 March 1998), which is intended to define an acquisition environment that makes DoD the smartest, most responsive buyer of the best goods or services that meet our warfighters' needs at the best dollar value to the DoD over the life of the product. DoD 5000 2-R policy is implemented in the area of ATS by: 1) leveraging non-recurring investments already made in ATS Families across multiple applications; 2) evolving the capabilities of these Families of ATS by migrating their commercial item content toward industry-wide standards; 3) facilitating intra- and inter-service level interoperability by encouraging common and interoperable support solutions; and 4) encouraging the use of commercial items within ATS Families and as ATS alternatives. To implement this policy, the DoD ATS Executive Agent was chartered to establish and maintain a waiver process for those programs that propose not to use the DoD designated standard families of ATS or commercial testers. Contrary to popular belief, the DoD ATS Selection Process has been established to facilitate the mission of the DoD Program Manager by helping him or her choose the most cost effective ATS solution that fulfils his or her mission support requirements. The DoD ATS family was not established to impose support solutions upon the DoD Program Manager, but rather to provide a variety of available and proven alternatives that may meet their needs while significantly reducing expected life cycle costs. Where obvious cost, schedule, or performance deficiencies exist with DoD family members for supporting a given weapon system, service ATS representatives provide the knowledge and expertise to help identify suitable alternatives View full abstract»

  • Fuel cells for “personal electricity”

    Cars powered by fuel cells have been built and tested; however, the aerospace fuel cells could not deliver high power quickly when the driver wanted to accelerate his car. Today's hybrid electric cars carry a battery that supplies the acceleration power, and the prime power source, whether an engine or fuel cell, is not stressed with sudden load peaks. Zero air pollution becomes attainable when fuel-cells supply the prime power on a hybrid vehicle View full abstract»

    Risk is the possibility of suffering loss. In a development project, the loss describes the impact to the project which could be in the form of diminished quality of the end-product, increased costs, delayed completion, or failure. This paper discusses the methods and techniques for identifying and managing the risks involved with Automatic Test Systems development View full abstract»

  • Fence vibrations [intruder detection]

    Many Perimeter Intrusion Detection Systems (PIDS) use microphonic sensors mounted on fences to detect intruder attacks. Vibrations in the fence are detected and analysed to determine whether they represent an intrusion attempt. The signals from the fence are processed to filter out as many false alarms as possible. It is important that the output from the sensors is linear along the fence, to ensure that there is no point on the perimeter less sensitive to intruder attack. The investigation reported in this paper aims to discover whether the performance of acoustic detection systems could be improved through research into fence acoustics. Using models of fence vibrations, sensors could be positioned to obtain a more linear response. In addition, through knowledge of the fence vibrations produced by both real attacks and the typical causes of false alarms, a system could be designed which could better distinguish between them, giving a lower false alarm rate and increased detection performance. Characteristic profiles were found for the different forms of attack to the fence. Although the investigation is still in its early stages, these attack profiles suggest that a new type of detection system could be designed based on profile recognition View full abstract»

  • Insertion of controller-pilot data link communications into the National Airspace System: is it more efficient?

    This paper proposes an application of the Total Airspace and Airport Modeller (TAAM)2 tool for determining the impact of new Communications, Navigation, and Surveillance (CNS) ground-based and avionics technology on the efficiency of the National Airspace System (NAS). TAAM presents an opportunity to attack this problem by simulating aircraft movements using rules that mimic actual operations. The rules can be tailored to represent local procedures, restrictions, and conflict resolution strategies, producing a realistic picture of aircraft movement. This paper describes a novel method for manipulating TAAM output to produce a measure of the voice channel occupancy (VCO) in a sector. This method can be applied for current conditions, where all communications use the voice channel, and for the future case in which Controller-Pilot Data Link Communications (CPDLC) is used to issue controller/pilot instructions. TAAM could then be used to examine the benefits of CPDLC in terms of relieving restrictions or reducing vectoring and holding. Overall system benefits such as reduction in delays or distance traveled could be estimated from the TAAM results View full abstract»
