Abstract: An apparatus comprises a transmitter, a receiver, an antenna and a signal cancellation circuit. The transmitter is configured to send a transmitter signal associated with a frequency. The receiver is associated with the frequency. The antenna is coupled to the transmitter and the receiver. The signal cancellation circuit is coupled to the transmitter, the receiver and the antenna. The signal cancellation circuit is configured to phase shift a first portion of the transmitter signal to produce a phase-shifted signal. The signal cancellation circuit is configured to combine the phase-shifted signal with a second portion of the transmitter signal to produce a combined signal. The second portion of the transmitter signal is associated with a reflection of a third portion of the transmitter signal from the antenna. The first portion, the second portion and the third portion of the transmitter signal are different from each other.

Abstract: A system, communications device, method and computer program product for implementing antenna diversity may include a first switch to selectively connect a first radio section to one of a plurality of antennas and a second switch to selectively connect a second radio section to one of the plurality of antennas. The system may also include an antenna detector to detect which one of the plurality of antennas is connected to a port of the first radio section and to a port of the second radio section.

Abstract: Putty-like gap-filling compounds for insulation that can be utilized at temperatures from about ?420° F. (?250° C.) up to about 500° F. (260° C.) are described herein. Embodiments of these compounds contain about 25-50 volume percent base material, about 50-75 volume percent microspheres, and about 0.1-0.3 volume percent catalyst. Embodiments of these compounds contain about 70-80 weight percent base material, about 20-30 weight percent microspheres, and about 0.1-0.5 weight percent catalyst.

Abstract: A wireless communication terminal includes a broadcast signal frequency converter that is communicatively coupled to the terminal's communication signal receiver and is configured to use its communication receiver to process received broadcast signals. In an exemplary embodiment, the converter includes a frequency shifting circuit, e.g., a block frequency converter, that shifts broadcast signal bands into communication signal bands, such that received broadcast signals are shifted into a frequency range compatible with the communication receiver's signal path. Moreover, the significant digital domain signal processing capability of the communication receiver can be used to receive broadcast television and/or radio signals, provide signal enhancements, and extract other types of information such as RDBS, IBOC, etc.

Abstract: A method and apparatus for reducing ingress noise (304) in the upstream frequency band and reducing power consumption in a cable communication system (200) by not allowing signals generated in the customer premise (104) to enter the upstream frequency band on the cable network (110) unless a customer premise device (102) is attempting to establish a communication link. An RF detector (206) monitors the signals on the coaxial cable for an RF signal. The comparator (208) indicates to the logic circuit (210) when the RF signal has exceeded a minimum threshold. The logic circuit (210) determines if the subscriber premise device (102) is attempting to establish a communication link. If the subscriber premise device (102) is transmitting the logic circuit (210) closes the ingress switch (212) to connect the subscriber premise device (102) to the network.
