  • Lossless power conversion to DC method and device
    Patent number: 9793807
    Abstract: A device and a method for power conversion to DC using zero-current and/or zero-voltage switching. Provides output voltage of any level and polarity. Operates with any input voltage, including DC and AC. Power loss is substantially eliminated. The conversion efficiency is independent of load consumption, from the idle to the maximum power. The EMI level is very low. Provides for input to output isolation without use of transformers.
    Type: Grant

  • Excessive ground-closure rate alarm system for aircraft
    Patent number: 4868916
    Abstract: An alarm means including a digital microcomputer having a memory programmed for storing a look-up table defining an alarm envlope which, above a predetermined altitude, is based on a relationship between altitude and ground-closure rate which is independent of ground velocity, and below said predetermined altitude, is based on a relationship between altitude and ground-closure rate which is dependent on ground velocity.
