  • Magnetic compass compensation system
    Patent number: 4327498
    Abstract: In a magnetic compass compensation system suitable for use within a ferrous land vehicle, a secondary magnetic sensor senses, the total magnetic field as components along a three axis system drawn vertical, lateral and transverse to the ferrous vehicle. Compensation signals corresponding to the permanent and induced magnetic fields of the vehicle are isolated from the total magnetic field. The compensation signals are applied to compensation coils surrounding a primary magnetic sensor for providing an output equivalent to the horizontal components of the earth's undisturbed magnetic field.

  • Aircraft power and phase converter
    Patent number: 4103325
    Abstract: A compact power and phase converter is adapted to utilize the single-phase and direct current power outputs of a conventional aircraft power supply, converting such outputs into stable three-phase power on wye-connected, grounded neutral distribution lines. An automatic current limiter provides overload protection for the converter when excessive output current is demanded.
