摘要： An apparatus and a method for detecting a carrier signal of a phase shift keyed modulated signal. A first counter circuit generates a plurality of counts, with each count being a number of cycles of a reference frequency signal occurring between two consecutive rising edges of an intermediate frequency signal. A comparison circuit compares a first count of reference frequency cycles to a second count of reference frequency cycles when a difference between an initial count of reference frequency cycles and a first predetermined number is less than a second predetermined number. The first predetermined number represents a time period of one cycle of the nominal center frequency, and the first count and the second count respectively represent time periods of first and second cycles of a pair of consecutive cycles of the intermediate frequency signal. The comparison circuit generates a difference signal when a difference between the first count and the second count is less than a third predetermined number. A second counter circuit counts cycles of the intermediate frequency signal and generates a carrier detect signal when a count of the intermediate frequency signal cycles equals a fourth predetermined number.

摘要： Methods of delivering electronic content include exchanging communications with a network access point from a control terminal to establish a communication link configured for two-way communications. Electronic content transmitted by the network access point is received at a remote terminal over the established communication link without providing responsive communications to the network access point from the remote terminal.

摘要： 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.

摘要： 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.

摘要： 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.

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.
