  • Doppler distance measuring system
    Patent number: 4218977
    Abstract: 3.
    Type: Grant
    Filed: May 19, 1959

    Inventor: Henry P. Kalmus
  • Tire pressure indicator
    Patent number: 4074227
    Abstract: An improved system is disclosed for electro-magnetically monitoring the condition of a vehicle tire which has a plurality of possible states, such as an internal air pressure which can fall within predetermined limits. The system is of the type which comprises a transmitter which serves to transmit to the monitored vehicle tire an interrogation signal composed of a carrier wave modulated at a predetermined modulating frequency. The tire to be monitored carries a transponder device which is operable in response to the state of the tire for passively detecting the modulating frequency of the interrogation signal and retransmitting an information signal at the modulating frequency. A receiver is provided responsive to the retransmitted information signal so as to provide an output which is indicative of the state of the device being monitored.
    Type: Grant

  • Ultrasonic remote control system
    Patent number: 4064806
    Abstract: Transmission of control information from one location in a solid structure o one or more remote locations in that structure is accomplished with ultrasonic surface waves transmitted along the structure. The ultrasonic carrier is frequency-modulated to cause the resulting standing wave patterns in the structure to be spatially shifted at the modulation frequency and thereby avoid permanent vibration nodes at receiver locations. The invention has particular utility in munitions structures.
