Abstract: A method and apparatus for compensating for input threshold variations in input buffers is provided. The method and apparatus compensate for input threshold variations by applying a bias voltage on a known capacitance of an RC calibration circuit using, for example, a pulse width modulator. The bias voltage helps ensure that the time to charge the known capacitance from the bias voltage to the input threshold voltage of the input buffer is independent of the threshold voltage. The bias voltage is chosen using an iterative process in which the time to charge from the bias voltage to the threshold voltage is compared with a reference time. The bias voltage is adjusted based on the comparison.

Abstract: A system includes a radar antenna and a radar controller. The radar controller generates two narrowband radar signals, each narrowband radar signal having substantially constant frequency, the frequencies of the two narrowband radar signals differing from one another. The controller operates the radar antenna to transmit each of the generated narrowband radar signals as a transmitted signal, each transmitted signal being characterized by a transmitted power. The controller also measures a received power of received signals that are received by the radar antenna, each received signal including a portion of a corresponding one of the transmitted signals that was returned from an object or from a calibration surface at a known calibration range. A processor operating in accordance with programmed instructions calculates a range to the object on the basis of the transmitted and received powers.

Abstract: A transmitting device (100) transmits a first packet, comprising a second encryption vector, that is encrypted using a first encryption vector. The transmitting device transmits a second packet that is encrypted using the second encryption vector if an acknowledgement message is received within a predetermined time after transmitting the first packet; otherwise, the first packet is re-transmitted. Upon receipt of the first packet, a receiving device (102) decrypts the first packet using the first encryption vector and transmits the acknowledgement message. Upon receipt of the second packet; the receiving device attempts to decrypt a portion of the second packet using the first and second encryption vectors. If the portion of the second packet was successfully decrypted using the first encryption vector, the receiving device re-transmits the acknowledgement message for the first packet; otherwise, it transmits an acknowledgement message for the second packet.

Abstract: A method and apparatus for frequency correction of a signal in a wireless local area network (WLAN) communication system is disclosed. The signal is processed to determine a frequency offset estimate which is a frequency deviation of the signal from a local oscillator. The signal is then shifted by an amount corresponding to a frequency correction estimate where the frequency correction estimate is an averaged value of the frequency offset estimate and at least one prior frequency offset estimate. Finally, the frequency correction estimate is utilized to correct signals in the WLAN communication system.

Abstract: A method and system for retransmitting data packets in a communication system having variable data rates is disclosed. In a preferred embodiment, data packets are packetized to an atomic packet size equal to that of a lowest rate packet. If a data packet requires retransmission at a rate different than that at which the data packet was initially transmitted, the rate is dynamically changed based upon a multiple of the atomic packet size.

Abstract: A method of reducing power consumption in a communication device includes a step of acquiring a signal on a common pilot channel of a radio communication system. A next step includes detecting predetermined bits in the signal on the common pilot channel indicating activity on paging channels of the radio communication system. When no paging channel activity is indicated in the second step, a last step includes powering down portions of the electrical circuitry of the communication device so as to reduce power consumption, and when paging channel activity is indicated in the second step, a next step includes powering up portions of the electrical circuitry of the communication device such that those paging channels indicating activity are monitored by the communication device.

Abstract: A current mode of operation is provided to a Walsh spreader (203), and based on the current mode of operation, the Walsh spreader (203) either varies a Walsh code at a symbol rate, or holds the Walsh code constant. During multi-carrier transmission a first symbol within a data stream (210) is spread with a first Walsh code, while symbols immediately preceding and following the first symbol are spread by a another, differing Walsh code. The sequence of Walsh codes exiting the spreader (201) is further scrambled by a pair of Pseudo-Noise (PN) codes (224) that are held constant for three Walsh code periods during multi-carrier transmission, and are not held constant during direct-spread transmission.

Abstract: Aspects of the disclosure permit agile acquisition of a location service in a device. In one aspect of such acquisition, the device can rely on location signals available globally in order to determine a region associated with the device, and in response to determination of the region, the device can acquire service information representative or otherwise indicative of the location service based at least on the region. In another aspect, the device can be configured to consume the location service. The agility of such acquisition can stem from the absence of (i) scanning for location services associated with the area in which the device is present and/or (ii) a predefined pool of location services established in production of the device.
