  • Patent number: 5898400
    Abstract: A velocity/speed measurement radar unit incorporates a handle assembly for detachment from a base unit to allow for convertibility from a hand-held unit to a remote controlled radar unit. The removable handle assembly controls the operating parameters and secondary functions of the radar unit in a simple and user friendly manner. The operating parameters are established using multifunctional switches incorporated in the handle assembly, such as a trigger-type switch, rocker switches, and push button switches. The secondary functions are similarly controlled using a rotary encoder/push button switch combination. A microprocessor in the handle assembly receives inputs from the multifunctional switches and generates a corresponding control signal for transmission to the base unit. The handle assembly and base unit communicate via infra-red transmitters and receivers. The handle assembly is ergonomically designed to insure ease of use.
