  • Method for monopulse single beam phased array tracking for communications using beam jitter
    Patent number: 11846699
    Abstract: A need exists for a method to do monopulse tracking with a single beam phased array antenna. With a monopulse tracker antenna, the satellite, or moving target, will have a beacon signal that the tracker can acquire. The beacon signal may be a preamble in the transmitted signal from the satellite. The monopulse tracker antennas are scanned over the volume, minimizing the error signal. When the error signal is minimal, the antenna is pointed in the direction of the satellite or moving target. Because the tracker needs to know direction offsets in both azimuth and elevation planes, error signals from both planes are needed. The monopulse tracker antenna maintains a radio frequency link to the beacon signal, causing the antenna to lock in the direction of the satellite when the error signal is minimized to zero.

  • Electro-magnetic kinetic energy harvesting device using increased magnetic edge area
    Patent number: 7948124
    Abstract: An energy harvesting apparatus comprising: a substrate; two magnets coupled to the substrate in close proximity to each other with like magnetic poles facing each other creating a flux gap; a coil coupled to the substrate and disposed within the flux gap, wherein the coil and the magnets are coupled to the substrate such that substrate acceleration causes relative motion between the magnets and the coil thereby exposing the coil to a changing magnetic flux.
