  • Electrostatic shock prevention device for use in vehicles
    Patent number: 5825605
    Abstract: A driver or passenger in a vehicle will often experience an electrostatic shock on exiting the vehicle. The invention solves this problem in a simple but effective manner by providing an appropriate discharge path. The finger recess in the door handle is lined with a conductive material which is connected to the metallic structure of the door, or otherwise to the vehicle body. This measure prevents the accumulation of an electric potential between the driver or passenger and the vehicle so that no discharge occurs.

  • Antenna pointing mechanism
    Patent number: 5389940
    Abstract: An antenna pointing mechanism for a highly directional antenna which avoids the aforenoted problems. The mechanism including the antenna are rendered substantially immune to bending and play-induced movements resulting from vibration or the like, making it highly useful for land based vehicles, ships, and particularly for aircraft. It also provides the ability to point the antenna over elevational angles exceeding 180.degree., making it particularly useful for communication with satellites from aircraft.
