  • Apparatus for the controlled release of an elevator hoist brake
    Patent number: 5228364
    Abstract: Apparatus (20) is provided to enable a single operator to effect a controlled release of an elevator hoist brake (32) thus allowing "drifting" of the elevator car to the nearest floor and quick safe rescue of trapped passengers during an electrical outage. Other apparatus (120, 130) is provided which may be combined with elements of the apparatus 20 to release brakes on special types of elevators. An additional arrangement (20') of the apparatus 20 is provided to release brakes on still other special types of elevators. An observer having the elevator car in view may communicate (e.g. by hand held transceiver) desired car movements to the operator who is typically located in the machine room atop the elevator shaft.

  • Variable effort joystick
    Patent number: 5228356
    Abstract: A variable resistance joystick (20) configured for computer control is provided. A stepper motor (34) turns threaded screws (30) to move a system of springs (26) up and down on the joystick thus varying the lever arm on which the springs impart force. Thus computer commands (113) to the stepper motor may change the force required by a user to move the joystick. A similar system controls the resistance to movement of a button (108) in the joystick handle (42).

    Patent number: 5226661
    Abstract: A method of apportioning wagers is disclosed which increases player interest and involvement in games where players successively become the "bank," i.e., wager against each of the other game players. The method offers the bank a plurality of wagering options.

  • Hearing aid having a liquid transmission means communicative with the cochlea and method of use thereof
    Patent number: 5176620
    Abstract: A hearing aid (100) is provided for surgically implanting in the ear of a subject. A liquid filled tube (142) is positioned between an orifice of the cochlea and a subcutaneous amplifier (200). A microphone (122) converts sound waves outside the subject into electrical signals which are amplified by the amplifier and are converted back into amplified mechanical motion by a transducer means (124). The amplified mechanical motion is transmitted through the tube by the liquid to the cochlea bypassing the outer and middle ears. The liquid and dimensions of the tube are selected to substantially match the acoustic impedance of the cochlea at the distal end of the tube.
