Abstract: Operating a game controller to identify a user by receiving touch pad input from at least one touch sensitive pad of the game controller that has a plurality of touch sensitive elements. The touch pad input corresponds to the user's touch of at least some of the plurality of touch sensitive elements. The touch pad input is at least partially processed by processing circuitry of the game controller and transmitted to a game console via a communications interface of the game controller for processing of the at least partially processed touch pad input to identify the user via pattern recognition. At least partially processing the touch pad input can be by identifying at least one finger orientation, at least one finger spacing, at least one finger width, a plurality of finger knuckle/joint locations, and/or a plurality of finger lengths based upon the touch pad input.

Abstract: The present invention relates generally to analog-to-digital converters (ADCs). Embodiments of the present invention provide novel ADC architectures directed at reducing the overall ADC area and power consumption. Embodiments of the present invention may be used in pipelined ADCs, cyclic ADCs, and successive approximation (SAR) ADCs, for example. Further, embodiments of the present invention may be implemented using both single-ended and differential configurations.

Abstract: An amplifier system can include an input amplifier configured to receive an analog input signal and provide an amplified signal corresponding to the analog input signal. A tracking loop is configured to employ delta modulation for tracking the amplified signal, the tracking loop providing a corresponding output signal. A biasing circuit is configured to adjust a bias current to maintain stable transconductance over temperature variations, the biasing circuit providing at least one bias signal for biasing at least one of the input amplifier and the tracking loop, whereby the circuitry receiving the at least one bias signal exhibits stable performance over the temperature variations. In another embodiment the biasing circuit can be utilized in other applications.

Abstract: Reliable and efficient sensing becomes increasingly difficult in harsher environments. A sensing module for high-temperature conditions utilizes a digital, rather than analog, implementation on a wireless platform to achieve good quality data transmission. The module comprises a sensor, integrated circuit, and antenna. The integrated circuit includes an amplifier, A/D converter, decimation filter, and digital transmitter. To operate, an analog signal is received by the sensor, amplified by the amplifier, converted into a digital signal by the A/D converter, filtered by the decimation filter to address the quantization error, and output in digital format by the digital transmitter and antenna.
