摘要： An event-triggered pairing mechanism allows pairing wireless devices having short range interfaces (e.g., Bluetooth devices) by bumping the wireless devices together. A wireless device being paired with a connecting device detects a bump event; exchanges time information about the bump event with the connecting device; authenticates the connecting device based on the exchanged time information; and allows exchange of user data with the connecting device based on verification of the exchanged time information. Once the devices are paired, user content can be securely exchanged between the devices.

摘要： An electronic device has a display, a controller, and a pair of haptic transducers connected to the display. The controller configures the haptic transducers to momentarily vibrate the display. A pair of sensors disposed on the display detects variations caused by the user touch in the vibrations. Based on an analysis of these variations, the controller can determine the location of the user touch on the touch-sensitive display.

摘要： The wireless receiver of the present invention accommodates dual-carrier Evolved EDGE without significantly impacting existing receiver architectures. The inventive receiver comprises a shared local oscillator and two image-rejecting downconverters. The local oscillator generates a local oscillator frequency between two carrier frequencies of adjacent radio channels. The receiver receives a signal in each of the adjacent radio channels. In a dual-carrier mode, a first image-rejecting downconverter uses the local oscillator frequency to downconvert a first signal received in the first radio channel while rejecting a second signal received in the second radio channel. A second image-rejecting downconverter uses the local oscillator frequency to downconvert the second signal while rejecting the first signal. In a diversity mode, the first and second image-rejecting downconverters use the local oscillator frequency to downconvert the signal received in one of the radio channels while rejecting the signal received in the other radio channel.

摘要： The wireless communication device and corresponding method described herein selectively switches between a single-frequency mode, such as appropriate for an EDGE network, and a multiple-frequency mode, such as appropriate for a multi-carrier EDGE network. Accordingly, a transmitting wireless communication device selectively switches between a single-channel mapping unit, used during the single-frequency mode, and a multi-channel mapping unit, used during the multiple-frequency mode. The multi-channel mapping unit modulates input data to output a modulated data stream for each of multiple adjacent frequency channels that, when combined, produce a multiple-frequency signal with reduced peak-to-average ratio. A receiving wireless communication device selectively switches between a single-channel demodulator, used during the single-frequency mode, and a multi-channel demodulator, used during the multiple-frequency mode.

摘要： A technique for supplying alternative contact information when a communication attempt is unsuccessful is described. The technique comprises receiving an inquiry that includes an indication of an unsuccessful communication attempt and an identifier or address for the target of the failed communication attempt. Next, it is determined whether the identifier or address is associated with a group. If so, a response is generated, the response including one or more other identifiers or addresses associated with the group. Finally, the generated response is transferred in response to the inquiry.

摘要： Methods and apparatus for processing received signals in a multi-carrier system are disclosed. An exemplary method includes estimating one or more first propagation channel coefficients based on a training sequence in each of one or more first slots received over a first radio channel, equalizing signal samples from one or more second slots received over a second radio channel immediately frequency-adjacent to the first radio channel, using the first propagation channel coefficients, and demodulating user data bits from the equalized signal samples. In some embodiments, the training sequence is located at a fixed position in each of the one or more first slots and user data bits are demodulated from a directly corresponding position in each of the second slots. Improved data rates are thus achieved by constraining radio carriers in a multi-carrier system to frequency-adjacent channels and eliminating training symbols from one of the signals.

摘要： A mobile terminal reduces its power consumption by selectively switching between a diversity mode and a non-diversity mode. The mobile terminal monitors the total output power of two or more of its transmitters, and selectively switches between the diversity mode and the non-diversity mode based on the total output power. The mobile terminal may also selectively switch between the diversity and non-diversity modes based on a difference in output power levels between the two or more transmitters.
