  • Articulated transformer for measuring torque on a rotating shaft
    Patent number: 6366218
    Abstract: The use of an articulated transformer whose windings do not completely encircle the shaft, and with a small gap in-between being provided so that the mounting structure can be opened and the windings slipped over the shaft before being closed once again to form a tuned transformer resonating at the frequency of an electrical power oscillator connected to transmit electrical power from a first location towards a second location.
    Type: Grant
    Filed: August 23, 1999
    Date of Patent: April 2, 2002
    Inventor: Clyde L. Ruthroff
  • Apparatus for measurement of torque on a rotating shaft
    Patent number: 5801644
    Abstract: Apparatus for measuring the horsepower transmitted by the drive shaft of an automotive vehicle, by determining the torque on the shaft through the measurement of the resistance of an included strain gauge, yet without the need for a power supply, such as a battery, being on the rotating shaft itself.
    Type: Grant
    Filed: December 2, 1996
    Date of Patent: September 1, 1998
    Inventor: Clyde L. Ruthroff
  • Apparatus, employing capacitor coupling for measuremet of torque on a rotating shaft
    Patent number: 5736938
    Abstract: Apparatus for measuring the horsepower transmitted by the drive shaft of an automotive vehicle, by determining the torque on the shaft through the measurement of the resistance of an included strain gauge, yet without the need for a power supply, such as a battery, being on the rotating shaft itself, and by employing a capacitive coupling to transmit power and signal to and from the drive shaft and fixed part of the vehicle.
