Abstract: A system for powering an electric vehicle includes two independent rechargeable batteries. Each battery of the two independent rechargeable batteries includes one or more battery cells. There is circuitry for charging each of the two independent rechargeable batteries and circuitry for drawing electrical energy from one or both of the two independent rechargeable batteries such that during normal operation of the electric vehicle, a first battery of the two independent rechargeable batteries is charged from any available charge potential (e.g., power from generators or solar power) and a second battery of the two independent rechargeable batteries is utilized to power the electric vehicle.

Abstract: Cordless antenna apparatus for determination of the location of an observer and/or of the time of observation by use of a Satellite Positioning System (SPS), such as the Global Positioning System or the Global Orbiting Navigational Satellite System. In each embodiment, the apparatus includes a Smart Antenna device and a display unit, connected by a wireless link. In a first embodiment, the Smart Antenna device includes: an SPS antenna to receive the SPS signals; an SPS signal frequency downconverter; an SPS signal processor to receive antenna output signals and to determine at least one of the present location of the SPS antenna or the time of observation; a transmitter to receive processor output signals and transmit these signals to the display unit; and a power supply.
