An audio playback device and method searches initiates a web search for images related to music or other audio files being played, downloads images from selected web pages returned by the search engine, and outputs one or more images from the selected web pages on a display to enhance the user's listening experience.

Two or more video streams including a high quality video stream and a low quality video stream are simultaneously transmitted to the video receiving device over the wireless network. All of the video streams carry the same video content but with different video quality. The high quality video stream is encoded using an unequal error protection code so that first components (e.g., high frequency components) receive a higher level of error protection than second components (e.g., low frequency components). The video receiving device can select the high quality video stream when channel conditions are favorable. When channel conditions are not good enough to support the high quality video stream, the video receiving device determines whether the first components of the high quality video stream with the greater error protection are usable. If so, the video receiving device combines the first components of the high quality video stream with the low quality video stream. Otherwise, the video receiving device outputs the low quality video stream.

A method and a system are provided for controlling a controller without physically touching the controller. A hand or other object interacts with a field surrounding the controller, altering the field. A change in characteristic of the altered field causes a corresponding movement of the controller that, in turn, corresponds to an amount of change in a parameter of a target device being controlled by the controller. The parameter of the target device is controlled by the controller while a user has no physical contact with the controller.

Methods of securely communicating a message from a first terminal to a second terminal include generating a keypad including a random sequence of bits having a length L, encrypting the message at the first terminal using a bit string beginning at an offset O in the keypad, and transmitting the encrypted message and an indicator of the offset O to the second terminal. A communication terminal includes a controller, a communication module configured to establish a location-limited communication channel, and an encryption unit configured to store a keypad including a random sequence of bits having a length L, to encrypt an outgoing message using the keypad, and to decrypt an incoming message using the keypad.
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.

A device and method for rerouting a communication from a first communication device to a second communication device includes a rerouting circuit. The rerouting circuit is operative to reroute a communication intended for the first communication device to the second communication device. Rerouting of the communication may be initiated by sending a rerouting request from the device not intended to receive the communication.
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:
A wireless terminal includes a Bluetooth module that communicates first information with a remote Bluetooth device, and a processor that selectively encodes the first information based on whether the remote Bluetooth device supports the enhanced communication mode. The wireless terminal can include a cellular transceiver that communicates second information with a cellular network according to a cellular communication protocol. In the enhanced communication mode, the processor may use one or more signal processing operations to encode the first information for transmission to the remote Bluetooth device that are also used to encode the second information for transmission to the cellular network.
摘要:
A mobile terminal includes a processor that is programmed to provide a user of the mobile terminal with a hearing test and to determine a set of coefficients. A microphone is configured to receive audio signals therethrough. A digital filter is programmed with the determined set of coefficients and is configured to process the audio signals and transmit the processed audio signals to an earphone.
摘要:
Memory systems include an array of storage cells arranged in a row and column arrangement. A plurality of data write lines coupled to the array are configured to supply data into a selected row of the array. A plurality of data read lines coupled to the array are configured to receive data from a selected column of the array in a single read operation. An arithmetic operation circuit coupled to the plurality of data read lines is configured to generate a result value based on data read from the storage cells of a selected column of the array. Methods of detecting a pattern, such as a color code pattern, are also provided.
