Abstract: Temperature of a processor is monitored and managed by a control circuit. A thermal diode is positioned to indicate the temperature of the processor. A controller measures a voltage across the thermal diode and calculates a temperature of the thermal diode as a function of the voltage and a correction factor. The correction factor is a constant value that is determined based on 1) a negative correlation between the voltage and a reference temperature of the thermal diode, and 2) a positive correlation between a resistance of the thermal diode and the reference temperature. The controller causes the processor to alter an operation in response to the temperature being above a threshold.

Abstract: The present disclosure provides a displacement amplification structure and a method for controlling displacement. In one aspect, the displacement amplification structure of the present disclosure includes a first beam and a second beam substantially parallel to the first beam, an end of the first beam coupled to a fixture site, and an end of the second beam coupled to a motion actuator; and a motion shutter coupled to an opposing end of the first and second beams. In response to a displacement of the motion actuator along an axis direction of the second beam, the motion shutter displaces a distance along a transversal direction substantially perpendicular to the axis direction.

Abstract: A microelectrical mechanical system (MEMS) implementation of tunable Fabry Perot filter devices is disclosed. The advantages associated with the use of these tunable etalons include increases in aperture size, displacement, reliability, and a reduction in cost. In some examples, integrated tunable detectors in miniature spectrometers using a thermal driven MEMS Fabry-Perot tunable filter are provided. Other examples use integrated thermal driven tunable MEMS Fabry-Perot filter to select fiber optical communication channel.

Abstract: A method and apparatus for sensing accelerations directed along multiple directions are provided. An embodiment comprises a sensor array comprising two sensor pairs, each of which provides an output signal based on acceleration along two orthogonal directions. The sensor pairs are so that they collectively provide an output signal for each of three mutually orthogonal directions. In some embodiments, the sensor array is augmented to provide three additional signals, each of which is based on rotation about an axis aligned with one of the three orthogonal directions.
