  • Patent number: 6822551
    Abstract: A method and apparatus for the purpose of ensuring positioning between a fixed automatic fueling service terminal and a vehicle, such that the vehicle is identified within a close range and authorized to dock at an identified service terminal to exchange services. This is accomplished by wirelessly determining the proximity of a couplable vehicle, with respect to a docking location at the service terminal. When a vehicle is within a specified distance of an automatic fueling service terminal, known as the zone of proximity detection, the vehicle identification code and service terminal identification code are both continuously determined and passed to a multi-port station controller, for authentication of service transactions and secure service processes, including automatically fueling the vehicle.

  • Patent number: 6817879
    Abstract: Various service port configurations for the transfer of fluids, gases and electricity between a service terminal and a vehicle are provided. The service port includes a receptacle and a controller. The receptacle includes a clamp and a clamp actuator for actuating the clamp; a service exchange interface in between the clamp; and sensors inside the receptacle and configured to monitor the position of a plug inside the receptacle. The controller is connected to the sensors and the actuator, and monitors the sensors. When a sensor detects that a plug is in position for engagement, the controller instructs the clamp actuator to move the clamp until the plug is clamped with sufficient force to enable a service to be exchanged. The receptacle and the plug are couplable to either the service port or a vehicle and a service terminal, and both are implementable at a multiplicity of locations on a vehicle.

  • Patent number: 6810925
    Abstract: A hydrogen fueling station and system for hydrogen fueled vehicles that can transfer any gaseous fuel to any vehicle and can be located in any place where a vehicle can park and where environmental, safety and other regulatory requirements permit gaseous fuel to be transferred. The hydrogen fueling station is vertically elongate and includes an enclosure that has a plurality of housings to house groups of like components. The housings are configured and positively ventilated with external air to prevent the accumulation of leaked hydrogen.

  • Patent number: 6619342
    Abstract: This invention relates to a wheel stop service port for coupling to a connectivity device of a wheeled vehicle such that one or more services, namely electricity, data, and fluids, are transferable therebetween. The service port includes a housing having a receptacle recess with a recess opening on an outside surface of the housing; a fastener on the housing for fastening the service port to the ground; a receptacle inside the recess and comprising an opening shaped to receive a service plug of a vehicle connectivity device, and a service engagement portion inside the receptacle for engaging a corresponding service engagement portion on the plug; a service conduit junction coupled to the receptacle and couplable to a service conduit to enable the transfer of a service therebetween; and a wheel contact surface located on the housing outside surface such that upon contact of the contact surface by a wheel of a vehicle, the connectivity device of the vehicle is within coupling range of the service port.

  • Publication number: 20030127155
    Abstract: This invention relates to a connectivity device for passively connecting a vehicle to a service port. The connectivity device comprises a mount for mounting to one of the vehicle or service port; a deployment apparatus movably attached to the mount; a plug for coupling to a receptacle in the other of the vehicle or service port; and, a compliant member attaching the plug to the deployment apparatus. The compliant member provides sufficient compliance for the plug to engage the receptacle when the connectivity device is in range of but not perfectly aligned with the receptacle.
