    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, determines time information about the bump event, and then generates a private session key based on the time information. Once the devices are paired and the private session key is generated, user content can be securely exchanged between the devices.

    摘要: The dual-mode processor 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. The pulse-shaping filters used during the multiple-frequency mode have a different filter response than the single-channel filter used during the single-frequency mode. The filter response of the pulse-shaping filters used during the multiple-frequency mode reduces cross-channel interference caused by the data symbols of two or more adjacent frequency channels that have the same or similar modulation and power level.

    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: 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: 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.
