  • Audio signal processing
    Patent number: 8831254
    Abstract: Systems and methods of processing audio signals are described. The audio signals comprise information about spatial position of a sound source relative to a listener. At least one audio filter generates two filtered signals for each of audio signal. The two filtered signals are mixed with other filtered signals from other audio signals to create a right output audio channel and a left audio output channel, such that the spatial position of the sound source is perceptible from the right and left audio output channels.

  • Dynamically adjusting drive signals for full bridge phase shifted converter and current doubler synchronous rectifier
    Patent number: 8824168
    Abstract: A full bridge phase shifted power supply with synchronous rectification and current doubler and method for dynamically adjusting delay parameters thereof mainly have multiple delay parameter combinations respectively varying with multiple loads and embedded in a controller of the power supply. The delay parameter combinations serve to determine driving waveforms of two rectification switches of a synchronous rectification and current doubler circuit of the power supply. When the load of the power supply varies, the controller dynamically performs a corresponding delay parameter combination so as to vary the driving waveforms of the rectification switches of the synchronous rectification and current doubler circuit and enhance the operating efficiency of the power supply.

  • BOOSTED READ WRITE WORD LINE
    Publication number: 20140211578
    Abstract: One or more techniques or systems for boosting a read word line (RWL) or a write word line (WWL) of a two port synchronous random access memory (SRAM) bit cell array are provided herein. In some embodiments, a boosted control block is configured to generate a boosted word line signal configured to operate a RWL, a WWL, or a read write word line (RWWL). In some embodiments, the boosted word line signal includes a first stage and a second stage. For example, the first stage is associated with a first stage voltage level at a positive supply voltage (Vdd) voltage level and the second stage is associated with a second stage voltage level above the Vdd voltage level. In this manner, a read or write operation is boosted for an SRAM bit cell, because the second stage boosts a corresponding transistor in the SRAM bit cell, for example.
