  • Patent number: 5995804
    Abstract: A low power miniature repeater station is located on a vehicle such as a train, cargo ship, cruise ship or other vehicle which is expected to carry multiple paging receivers. The repeater station receives paging messages that originate as satellite signals and rebroadcasts them in the immediate vicinity of the vessel. The rebroadcast may typically be over a single FM carrier frequency or in the form of a subcarrier signal. The repeater includes an FM scanning receiver that samples the radio band and enables the rebroadcast of signals only if FM subcarrier signals are not detected within the vicinity of the vehicle. As the vehicle re-approaches a populated area, continued scanning of the radio band eventually detects the presence of subcarrier signals and shuts down the repeater to ensure that it will not interfere with licensed terrestrial broadcasters.

  • Patent number: 5042052
    Abstract: The invention involves an apparatus for recovering the carrier signal in OPSK or QAM data. First an energy directed phase detector controls a voltage controlled oscillator so that the output signal has a phase that is within a few degrees of the carrier phase. Following this coarse acquisition, the system clock timing is recovered and established. A decision directed phase detector, using the system clock information, then controls the VCO to adjust the output signal phase to within a very small tolerance of the actual carrier phase.

  • Patent number: 4951831
    Abstract: An improved plastic trash receptacle to support a plastic trash bag, expanding to admit approximately a maximum capacity of trash. A plurality of slots (10), are molded into the lower circumference of a receptacle (28), resulting in an equal number of flexible side panels (12), incorporating a reinforcement bead (34), along the edge of each side, and ends of slots. The panels bulge outwardly as trash is compacted into the plastic trash bag (22), figure (8). The bulging panels result from expanding slots (36). After a filled bag is securely closed, it may be lifted from the receptacle. If the receptacle lifts with the bag, the user places his toes over the hand toe grips (14), to keep the receptacle on the supporting surface while lifting the bag therefrom. If the filled bag is excessively heavy, the user tips the receptacle upside down, containing the securely closed bag. Again, utilizing the hand toe grips (14), the user lifts the lightweight receptacle from the filled bag.
