  • Patent number: 5311973
    Abstract: A battery of an electric vehicle is inductively charged while the electrical vehicle is moving, using a magnetic field along different portions of an extended linear distance and an inductive coil mounted on an electric vehicle, by having the electric vehicle, as it traverses the different portions of the extended linear distance, move within the influence of the magnetic field. An apparatus senses progress of the electric vehicle along the extended linear distance. The apparatus produces the magnetic field by a power switch bank connected to an array of inductive coils.

  • Patent number: 5297664
    Abstract: A parking meter and an electric charging meter are combined in a single apparatus. The combined charging/parking meter may be coin-operated or may be operated using an information-bearing card such as a cash card, a debit card or an IC card. In particular, the charging/parking meter includes a device for receiving and verifying a medium of payment, a device for selecting and visibly indicating some combination of parking time and electric power to be had in exchange for the medium of payment, and a charging device for connecting to and supplying power to an electric car charger inlet. The charger/parking meter may further include a fast-charge setting device for causing the charging device to operate in a fast-charge mode when an amount of parking time selected is insufficient in accordance with a normal charging mode to supply an amount of electric power selected.

  • Patent number: 4991201
    Abstract: A facsimile signal control system adapted to be connected between a facsimile machine and a telephone line, comprises an RF signal receiver adapted to receive and demodulate RF signals from an antenna, a change-over switch, a first port for connection to a facsimile machine, and a second port for connection to a telephone line and an interface circuit. A control circuit is connected to apply the demodculated facsimile signals from the signal receiver to the interface circuit. The control means further comprises means for controlling the change-over switch to selectively connect the first port to either the second port or the interface circuit.
