Abstract: A handheld mobile phone includes at least two buttons, a logic circuit, and a processing unit, wherein each button is used for performing at least one specific function. The logic circuit is coupled to the at least two buttons for generating a corresponding specific signal when one of the at least two buttons is pressed alone, and for generating at least a control signal when all of the at least two buttons are pressed. The processing unit executes the specific function of the pressed button according to the corresponding specific signal. When all of the at least two buttons are pressed, the processing unit controls the handheld mobile phone to enter a reset state from an operating state according to at least the control signal.

Abstract: A system and method for sharing a switched capacitor array (SCA) by two tuning circuits are disclosed. In a multiple-band radio receiver, there is a need to use multiple tuning circuits for signals in different bands. The tuning circuit typically comprised an adjustable capacitance device and other tuning components, where the adjustable capacitance device is often implemented in SCA. The present invention discloses a system and method comprising n sections of capacitor elements where each capacitor element comprises a capacitor and switches to selectively connect the capacitor to one of the tuning circuit. Consequently, the SCA can be shared by the two tuning circuits. The control bits for the switched may be provided from a programmable control register.

Abstract: A mobile station includes a radio channel condition measurement portion that measures a radio channel condition, a radio channel averaging portion that averages the measured radio channel condition over a predetermined period of time, and a reception mode control portion that allows switching to a measurement mode for measuring a different frequency and a different system to be realized in accordance with the averaged radio channel condition; and a base station includes a radio channel condition averaging portion that averages a radio channel condition received from a mobile station, over a predetermined period of time, and a transmission mode control portion that allows switching to a discontinuous transmission mode for performing a discontinuous transmission to be realized in accordance with the averaged radio channel condition.

Abstract: Methods and apparatus are provided for timeshifting audio content in a multiple tuner audio system comprising a first tuner and a second tuner. One operating method involves maintaining a first data storage element for the first tuner, maintaining a second data storage element for the second tuner, receiving first audio content in realtime by the first tuner, and storing data representing the first audio content in the first data storage element, resulting in first stored content. The method also receives second audio content in realtime by the second tuner, and stores data representing the second audio content in the second data storage element, resulting in second stored content. The method thereafter generates a timeshifted audio signal corresponding to the first stored content or the second stored content.

Abstract: A communication system utilizing an adjustable link has at least a first data transmission circuit including at least a first communication link circuit. The first communication link circuit has a baseband circuit and at least a passband circuit. The baseband circuit corresponds to a baseband sub-channel and the passband circuit corresponds to a passband sub-channel. The first communication link circuit also includes a circuit that distributes a first subset of a data stream having a first symbol rate to the baseband circuit and a second subset of the data stream having a second symbol rate to the passband circuit. The baseband sub-channel and the passband sub-channel are separated by an adjacent guardband of frequencies. The passband carrier frequency is adjusted to define the guardband and the guardband corresponds to a first notch in a channel response of a first communications channel.

Abstract: A tuneable radio and method for automatically adjusting the seek sensitivity alignment for seek operations. The radio has a radio receiver for receiving broadcast radio wave signals, and a tuner adjustable for selecting from a plurality of radio wave signal channels. A detector detects signal strength of the received radio wave signals, and a seek input allows a user to initiate a seek operation to select a signal channel having a signal strength exceeding a seek sensitivity threshold. A controller calculates an average signal value and adjusts the seek sensitivity threshold based on the average value. The controller adjusts the seek sensitivity when it is determined that the radio has travelled beyond a minimum distance.
