The closed loop tuning commences using a predetermined antenna tuner configuration for an operational band and device state. The closed loop tuning may be constrained by a tuning range associated with the predetermined antenna tuner configuration for the operational band and device state. Also, when transmit power is low or when a transceiver is in a receive only state, open loop tuning may be conducted by placing the antenna tuner in the predetermined (or default) configuration for the operational band and phone state. | 05-19-2011 |
20110126014 | Event Triggered Pairing of Wireless Communication Devices Based on Time Measurements - 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. | 05-26-2011 |
20110300812 | COMMUNICATIONS CIRCUITRY FOR AN ELECTRONIC DEVICE - Communications circuitry includes a controlled antenna tuner. The voltage across elements of the antenna tuner may be determined and, if an over-voltage situation is detected, remedial action may be taken. At times when a configuration of the antenna tuner is to be maintained and an over-voltage condition exists, the remedial action may include lowering an output power from a transceiver. Another type of remedial action may include introducing a phase shift between an antenna and the antenna tuner. At times when a configuration of the antenna tuner is to be changed and an over-voltage condition exists, the remedial action may include reducing output power of the transceiver. Another type of remedial action may include waiting for an opportune time to change the antenna tuner configuration. | 12-08-2011 |
20110310028 | Active Acoustic Touch Location for Electronic Devices - 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. | 12-22-2011 |
20120081337 | Active Acoustic Multi-Touch and Swipe Detection for Electronic Devices - 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 whether a user performed at least one of a swipe action and a multi-touch action, across the display. | 04-05-2012 |
20120154070 | Closed Loop Antenna Tuning Using Transmit Power Control Commands - A method and apparatus for closed loop antenna tuning uses power control feedback from a serving base station to infer the best impedance settings for an impedance matching circuit. The mobile terminal receives periodic power control commands from a base station and varies a transmit power of the transmit signal responsive to said power control commands. An antenna tuning circuit determines an impedance setting for an impedance matching circuit based on observed variations in the power control commands following adjustment in the impedance matching circuit. | 06-21-2012 |
20130083711 | Reuse of Training Sequence Between Frequency-Adjacent Radio Signals - 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. | 04-04-2013 |
20140344466 | PEER TO PEER CONNECTION - A method in a first device for setting up a peer-to-peer IP connection between the first device and a second device may include sending a request to a second device for setting up the peer-to-peer IP connection between the first device and the second device. The request may include an IP address of the first device. Alternatively, an IP address of the second device may be received in a message from the second device. The peer-to-peer IP connection between the first device and the second device is then set up. The setting up may be initiated by one of the parties associated with the first device or the second device by connecting to the other party using the IP address of the other party. | 11-20-2014 |
