20100251800 | Robust Self Testing of a Motion Sensor System - A method for self-testing a dual-mass linear accelerometer in which a self-test voltage is applied to urge the two masses to move in opposite directions. Self-test signals are then applied to obtain a differential mode signal to detect masses repositioned in opposing directions. During testing, common disturbances to the two masses are rejected as common mode signals. | 10-07-2010 |

20130278077 | ISOLATED MEASUREMENT SYSTEM WITH COOPERATIVELY-TIMED ISOLATED POWER GENERATION - A power delivery system is disclosed for an isolated measurement system in which a power transmitter and power receiver are provided at powered and unpowered sides of an isolation barrier, respectively. The power transmitter and power receiver may be coupled by an isolator. The power transmitter may deliver power to the power receiver to power components on the unpowered side of the isolation barrier. The system may include a controller provided in the powered side to generate a clock signal defining timing of a predetermined operation of the measurement system and to generate a disabling signal to the power transmitter controller synchronously with the timing of the predetermined operation. | 10-24-2013 |
20130278438 | ISOLATOR SYSTEM WITH STATUS DATA INTEGRATED WITH MEASUREMENT DATA - An isolator system is disclosed in which a pair of circuit systems is separated by an isolation barrier but engage in mutual communication by an isolator device that bridges the isolation barrier. A first circuit system may include a measurement system generating measurement data and status monitor generating status data. The first circuit system also may include a communication system that multiplexes the measurement data and the status data for transmission across a common isolator device. In this manner, the number of isolator devices may be reduced over conventional designs. | 10-24-2013 |
20130279611 | ISOLATED SYSTEM DATA COMMUNICATION - Embodiments of the present invention may provide a system with a first and second circuit system separated by an electrical isolation barrier but provided in communication by at least one isolator device that bridges the isolation barrier. The first circuit system may include a communication system to transmit data across a common isolator device as a series of pulses, and the second circuit system may receive the series of pulses corresponding to the data. The second circuit system may include a detector coupled to the common isolator device to detect the received pulses, a oneshot to frame the received pulse(s), and a controller to reconstruct the data based on accumulated framed pulse(s). Therefore, noise induced spurious pulses outside the oneshot intervals may be ignored by the second circuit system providing improved noise immunity. | 10-24-2013 |
20140119082 | ISOLATED DIGITAL TRANSMISSION WITH IMPROVED EMI IMMUNITY - Embodiments of the present invention may provide a circuit. The circuit may include a primary side, a secondary side, and an isolated energy transfer device electrically isolating the primary side and the secondary side. The primary side may include a first energy storage device coupled to a power source, a control system coupled to the first energy storage device for power, a second energy storage device, and a coupling system, coupled to the control system, to selectively couple the second energy storage device to the power source in a first phase and to selectively couple the second energy storage device to the primary side of the isolated energy transfer device during a second phase. | 05-01-2014 |
