Patent number: 7562581Abstract: 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.Type: GrantFiled: September 29, 2006Date of Patent: July 21, 2009Assignee: Case Western Reserve UniversityInventors: Steven L.

Patent number: 6961257Abstract: Pulse-width modulation (PWM) control and drive circuitry particularly applicable to an array of electrostatic actuators formed in a micro electromechanical system (MEMS), such as used for optical switching. The high-voltage portion may be incorporated in an integrated circuit having drive cells vertically aligned with the MEMS elements. A control cell associated with each actuator includes a register selectively stored with a desired pulse width. A clocked counter distributes its outputs to all control cells. When the counter matches the register, a polarity signal corresponding to a drive clock is latched and controls the voltage applied to the electrostatic cell. The MEMS element may be a tiltable plate supported in its middle by a torsion beam. Complementary binary signals may drive two capacitors formed across the axis of the beam. The register and comparison logic for each cell may be formed by a content addressable memory.Type: GrantFiled: March 12, 2004Date of Patent: November 1, 2005Assignee: Movaz Networks, Inc.Inventors: Steven L.

Patent number: 6788981Abstract: A multiplexed analog control system for an micro electromechanical systems (MEMS) array of electrostatic actuators, such as tiltable mirrors in an optical switch. Each actuator includes a variable gap capacitor formed as part of the movable mechanical element. A hold capacitor is connected to each actuator capacitor, and a selectable high-voltage inverter connects them to provide a bipolar drive signal of 50% duty cycle. A single power digital controlled current source is connected to all the drive circuits to provide a high-power correction signal. Address decoders enable a selected one of the drive circuits to add or subtract the correction from the hold capacitor.Type: GrantFiled: September 7, 2001Date of Patent: September 7, 2004Assignee: Movaz Networks, Inc.Inventors: Steven L.
