    摘要: Each user can contribute to an original search and to refining the results of the search. Preferences of all of the users are considered in the search even while those preferences can be kept private. In some embodiments of the present invention, at least two users each submit a search query. The multiple search queries are logically combined to produce one set of search results. The results can be reviewed by the users and refined if necessary. In some embodiments, a search query can be specified by a single user, but the search engine takes into consideration the stored preferences of multiple users (in addition to the search query itself, of course).

    摘要: During operation of a secondary communication system, cells (106) are formed by a plurality of localized nodes (104) to alert other nodes within the cell of frequencies which must be protected or otherwise avoided. All nodes within the cell monitor a differing subset of all frequencies available, and share information with respect to acceptable and protected frequencies with each other via low-power, short-range communication. Each node then forms a list of available channels for communication, and chooses a single node to report this information back to controller.

    摘要: During operation of a secondary communication system 100, a device will perform spectrum sensing of certain channels (either by itself or as part of a group of nodes 104). When activity is found on a channel from a primary user, other devices will be notified that the channel is not available for use. The device may then modify its spectrum sensing to assist another device (or group of devices) that have not yet found activity on a different set of channels. By assigning additional channels to devices with extra capacity, the overall spectrum-sensing efficiency and performance of the communication system 100 is raised.

    摘要: A sample circuit (10) maintains linear operation over frequency. A switchable diode bridge (12) passes the analog input signal when enabled to one terminal of a sample storage capacitor (14). The second terminal of the capacitor is coupled through a closed FET switch (16) to a reference node (18). Once the analog input signal is stored across the capacitor, the FET switch opens before the diode bridge disables. When the second terminal of the capacitor floats and prevents any further charge from altering the sample voltage across the capacitor. When the diode bridge is disabled, the sample voltage across the capacitor does not change. The sample voltage may be amplified and digitized for further processing in the cellular system.

    摘要: An apparatus and method for operating a phase locked loop frequency synthesizer responsive to radio frequency channel spacing. The phase locked loop (PLL) frequency synthesizer (300) tunes a radio frequency transceiver (100) to a radio frequency channel. A processor (110) in the transceiver (100) determines the channel spacing of the radio frequency channels in a portion of a radio frequency band including the radio frequency channel, and controls the PLL frequency synthesizer (300) responsive to the determined channel spacing. The present invention advantageously provides the PLL frequency synthesizer (300) with faster lock time and lower noise.

    摘要: A unique automatic battery charger (100) is described that recharges a battery (202) including a thermistor (206) for sensing the battery temperature. The charger (100) produces both a slow-charge current and a fast-charge current. Upon detecting the presence of the battery (202), the unique charger (100) turns on a fast-charge current produced by a switchable current source (110-113). The fast-charge current is subsequently turned off when the battery (202) is fully charged as indicated by the status of monitored temperature and voltage conditions. Comparators (180-184) are utilized to monitor these voltage and temperature conditions. According to a novel feature of the present invention, the monitored temperature thresholds are changed in response to the supply voltage. The automatic battery charging apparatus of the present invention may be advantageously utilized in a variety of applications for rapidly and safely charging batteries used in battery-operated electrical apparatus.

    摘要: A method and apparatus for allocating spectrum within a wireless communication system is provided herein. During operation, a first base station will determine a location of a UE wishing to transmit. A database will be accessed containing wireless coverage area information for base stations with overlapping coverage with the first base station. Based on this information the first base station will determine if the UE is within an overlapping coverage area of multiple base stations. Spectrum will be assigned to the wireless equipment in a guard band, based at least in part on the determination that the UE is not within the overlapping coverage area.
