    Eagle-Picher Energy Products (EPEP) has been manufacturing and testing large lithium ion cells (up to 100-Ah) for several years. Recently, work has focused on the testing of different chemistries at variable temperatures and designing and fabricating 100-Ah cylindrical cells. For the aircraft application the largest concern is irreversible capacity loss at elevated temperatures (70°C). In cont... View full abstract»

    COTS batteries are relatively inexpensive, readily accessible, and extremely versatile. These attributes allow the military to save time and money during the research and development stages. Of these COTS batteries, a 9-Volt (9 V) lithium/manganese dioxide battery is the subject of this paper. This 9 V battery has the ability to provide a low magnetic signature, which is very important to the Navy... View full abstract»

    GPS is an innovative technique for an electronic road pricing (ERP) system. By using GPS technology, ERP systems will be extremely efficient and cost-effective. This paper describes the next generation of ERP in Singapore and proposes a GPS based multisensor positioning system for ERP vehicles. Multisensor fusion algorithms are presented for the integration system. The integrated positioning syste... View full abstract»

    In the early 1960s, the first ideas were developed by leading companies in Germany to design an intrusion detection system following a capacitance measurement principle. In 1982, Siemens AG was the first company in this market which analysed all outdoor influences and recognised the essential problems which cause any classic capacitive or electrostatic detector to suffer from high unwanted false a...

    The VRAC, has the mission of applying virtual reality technology to the challenges of engineering and science. We typically create virtual worlds that allow the user to interact with 3D real-time graphics. We refer to the virtual worlds enabling this interaction as synthetic environments. A synthetic environment produces sufficient sensory cues to make users believe they are in a different geograp... View full abstract»

    We consider the problem of designing fault tolerant control for transient failures in the flight control system caused by harsh electromagnetic environments. We examine principles of fault tolerant design and discuss integrated local supervisory control of these systems. As an example, we present a sample design of a control mixer to achieve fault tolerance in the event of failures in the actuator... View full abstract»
