    摘要： A wireless local loop system is provided that includes a wireless base station that communicates with a subscriber station via a wireless link. The wireless link can carry a voice service, such as telephone calls, or a data service, such as internet browsing. The subscriber station includes a steerable antenna. A presently preferred steerable antenna for use with the subscriber station includes a driven element mounted on a base plane that is surrounded by a plurality of parasitic elements also mounted to the base plane. The parasitic elements can be optionally grounded or floated in order to reflect the wireless link towards the driven element. The antenna can be oriented in a desired direction during the transception of a voice or data service. A method of transceiving between a wireless local loop subscriber station and a wireless local loop base station is also provided.

    摘要： A fluid flow device includes an actuator, an RF transmitter, a gated RF receiver, and a processor. The RF transmitter is configured and arranged to produce a plurality of pulses of RF energy spaced apart in time to form a sensor field. The gated RF receiver is configured and arranged to receive RF energy reflected by objects within the sensor field. The processor is coupled to the gated RF receiver for evaluating the reflected RF energy. The processor is also coupled to the actuator and is configured and arranged to activate the actuator in response to the reflected RF energy to control fluid flow. In addition, a new low power radar sensor operates by providing radar pulses that are non-uniformly spaced in time. In operation, a burst of pulses is initiated in the transmitter. Between each burst is a period of rest time in which the transmitter is not transmitting RF energy.

    摘要： A toilet ventilation device includes a housing that defines an air inlet aperture and an air outlet aperture. Within the housing are an air movement apparatus for drawing air into the device, a filter for removing malodorous elements in the air, and a radar sensor for activating the air movement apparatus in response to the presence of a user and, optionally, deactivating the air movement apparatus when the user leaves. The toilet ventilation device is configured and arranged to draw air, using the air movement apparatus, from the toilet, through the air inlet aperture, into contact with the filter, and out the air outlet aperture. In one embodiment, the toilet ventilation device is disposed over the overflow conduit of the toilet to draw air from the bowl of the toilet, through the overflow conduit, and into the toilet ventilation device. The entire toilet ventilation device is preferably disposed within a tank of a toilet.
