  • Publication number: 20150349427
    Abstract: A wall-mountable wireless control device may include an antenna (e.g., a slot antenna or a hybrid slot-patch antenna) for transmitting and/or receiving radio-frequency signals, and may have a conductive material on a large amount (e.g., greater than or equal to approximately 85%) of a front surface of the control device. The wireless control device may operate consistently when installed with different types of faceplate assemblies (e.g., faceplate assemblies having metal and/or plastic components) and when installed with different types of electrical wallboxes (e.g., metal and plastic wallboxes). A faceplate comprising a conductive element may be installed on the wireless control device, such that the conductive element operates as a radiating element of the antenna. The wireless control device may comprise a conductive member (e.g., a conductive label or a conductive strap) extending around a rear enclosure of the wireless control device between opposite sides of a conductive yoke.

  • Publication number: 20150349402
    Abstract: A wall-mountable wireless control device may comprise a yoke, a faceplate assembly, an antenna, a radio-frequency communication circuit, and/or a control circuit. The radio-frequency communication circuit may be configured to transmit or receive radio-frequency signals via the antenna. The faceplate assembly may comprise a conductive element that is configured to operate as a radiating element of the antenna when the faceplate assembly is attached to the yoke. The conductive element may comprise a conductive material on the front surface of the faceplate. The conductive element may be attached to a rear surface of the faceplate (e.g., as a conductive backer). The conductive element may be located inside of the faceplate. The conductive element may comprise metallization applied to a plastic carrier of the faceplate. The faceplate assembly may comprise an adapter plate comprising a surface on which the conductive element is located.

  • Publication number: 20150349973
    Abstract: A wall-mountable wireless control device may include an antenna (e.g., a slot antenna or a hybrid slot-patch antenna) for transmitting and/or receiving radio-frequency signals. The wireless control device may comprise a user interface, an antenna, a radio-frequency communication circuit, a control circuit, and/or a conductive faceplate. The radio-frequency communication circuit may be configured to transmit or receive radio-frequency signals via the antenna. The user interface may be configured to receive a user input. The conductive faceplate may be configured to operate as a radiating element of the antenna when the conductive faceplate is mounted to the wireless control device and the user interface is received in the opening of the conductive faceplate. The conductive faceplate may comprise a conductive material arranged over a plastic carrier, for example, the conductive material may be provided adjacent to greater than or equal to approximately 85% of the front surface.

  • Publication number: 20150346702
    Abstract: A wall-mountable wireless control device may include an antenna, a radio-frequency communication circuit, a control circuit, an enclosure, a conductive yoke, and/or a conductive member. The antenna may be configured to transmit and/or receive radio-frequency signals. The radio-frequency communication circuit may be configured to transmit and/or receive the radio-frequency signals via the antenna. The control circuit may be responsive to the radio-frequency communication circuit. The enclosure may be configured to house the radio-frequency communication circuit and the control circuit. The conductive yoke may be attached to the enclosure and configured to mount the control device to an electrical wallbox. The conductive member may extend around a rear side of the enclosure between opposite sides of the yoke.

  • Patent number: 7983642
    Abstract: A system and method is provided for reducing signal distortion and saturation within an RF receiver which may be operated in an environment under the presence of interfering signals such as in a WiMAX environment. In an embodiment, a first gain stage and a second gain stage are selectively lowered to predetermined lower levels, assuring that if there is a blocker present, it would not cause signal distortion and saturation in the receiver. The loss of the gain in the first gain stage and second gain stage is compensated by a third gain stage which selectively amplifies the signals of interest. If a blocker is not detected, the maximum allowable gain of the first gain stage and the second gain stage is set to a predetermined upper limit allowing for maximum receiver sensitivity. Accordingly, with this system and method a direct conversional receiver can operate in the presence of interfering signals without signal distortion and saturation.
