  • Patent number: 9813229
    Abstract: A high frequency signal is down-converted into an intermediate frequency signal, transmitted over a limited bandwidth medium from a master unit to a remote unit and up-converted back into its original high frequency at the remote unit. The up-conversion is aided by reconstruction of a reference signal embedded at the master unit as a carrier for a management signal which is transmitted to the remote unit through the same limited bandwidth medium together with the intermediate frequency signal. The reference signal is reconstructed using a phase locked loop which includes a charge pump and is kept stable during intervals between bits and messages by a charge pump shutter.

  • Patent number: 8577286
    Abstract: One embodiment is directed to a system for use with a coverage area in which one or more wireless units wirelessly transmit using a wireless radio frequency spectrum. The system comprises a first unit, and a plurality of second units communicatively coupled to the first unit using at least one communication medium. Each of the plurality of second units generates respective digital RF samples indicative of a respective analog wireless signal received at that second unit. Each of the plurality of second units communicates the respective digital RF samples generated by that second unit to the first unit using the at least one communication medium. The first unit digitally sums corresponding digital RF samples received from the plurality of second units to produce summed digital RF samples. The system is configured so that an input used for base station processing is derived from the resulting summed digital RF samples.

  • Patent number: 8571513
    Abstract: For one disclosed embodiment, an integrated circuit may comprise an internal transmission line in one or more layers of the integrated circuit. The internal transmission line may be coupled to receive a signal from an external transmission line at a first end of the internal transmission line without use of termination circuitry. The internal transmission line may transmit the signal passively to a second end of the internal transmission line. The integrated circuit may also comprise first circuitry having an input coupled to the internal transmission line at a first location of the internal transmission line to receive the signal and second circuitry having an input coupled to the internal transmission line at a second location of the internal transmission line to receive the signal. The second location may be different from the first location. Other embodiments are also disclosed.

  • Patent number: 8509683
    Abstract: A two conductor hard wired communications link accepts an actual value of at least one parameter of interest from an environmental sensor in the form of data encoded on the conductors via current modulation. The sensor is mounted in location remote from an irrigation controller. A circuit connected to the sensor transmits an RF signal representing an actual value of a parameter of interest detected by the sensor. A data relay is connected to the hard wired communication link of the irrigation controller. The data relay includes a receiver that receives the RF signal, and circuitry configured to extract the actual value of the parameter of interest and emulate a predetermined set of physical and protocol properties of the hard wired communication link of the irrigation controller.

  • Patent number: 8463179
    Abstract: A repeater system is disclosed including a dual-fed donor patch antenna with a first microstrip antenna probe and a second microstrip antenna probe, phase shifting circuitry connected to the first microstrip antenna probe and the second microstrip antenna probe, wherein the phase shifting circuitry is configured to receive an input signal, supply a first signal to the first microstrip antenna probe, and supply a second signal to the second microstrip antenna probe using the input signal such that the first signal and the second signal are approximately 180 degrees out of phase with respect to each other. The repeater system also includes a coverage antenna (either a patch antenna or dipole antenna) and a housing connecting the dual-fed donor patch antenna and the coverage antenna. The housing is disposed to serve as a ground plane for the donor patch antenna and the coverage antenna.

  • Patent number: 8428511
    Abstract: A network architecture for underground communication using redundant interconnected communication systems utilizes an aboveground master control station to send a status request message to a belowground gateway. The gateway may then, in turn, broadcast a status request message to a plurality of communication hubs located throughout an underground region using each of a plurality of potentially available communication systems. In the event that one of the communication hubs fails to respond over the then-current communication system, the master control station may switch the current communication system being used to a truly available system.
