20130121499 | Frequency Domain Signal Processor For Close Talking Differential Microphone Array - A system and method for processing close talking differential microphone array (CTDMA) signals in which incoming microphone signals are transformed from time domain signals to frequency domain signals having separable magnitude and phase information. Processing of the frequency domain signals is performed using the magnitude information, following which phase information is reintroduced using phase information of one of the original frequency domain signals. As a result, high pass filtering effects of conventional differential signal processing of CTDMA signals are substantially avoided. | 05-16-2013 |
20130122628 | MEMS Relay and Method of Forming the MEMS Relay - A micro-electromechanical systems (MEMS) relay includes a switch with a first contact region and a second contact region that are vertically separated from each other by a gap. The MEMS relay requires a small vertical movement to close the gap and therefore is mechanically robust. In addition, the MEMS relay has a small footprint and, therefore, can be formed on top of small integrated circuits. | 05-16-2013 |
20130169262 | Methodology for Controlling A Switching Regulator Based on Hardware Performance Monitoring - A methodology for regulating power supplied to a powered component based on hardware performance, such as may be used in a system that includes the powered component and a switching regulator (EMU or energy management unit) configured to supply a regulated supply voltage to the powered component. Performance monitoring circuitry generates a performance monitoring signal corresponding to a detected performance level of selected digital operations of the powered component relative to a reference performance level. Switching control circuitry provides a switching control signal in response to the performance monitoring signal. In an example embodiments, the switching control circuitry for the switching regulator (switching transistor) is integrated into the powered component, and the detected performance level corresponds to a detected signal path delay associated with the digital operations of the powered component. | 07-04-2013 |
