Abstract: A temperature detector configured for use in a mobile terminal includes a lens, a collimator hole, and an infrared sensor that are arranged on an optical path. The lens is configured to converge ambient light, and the ambient light includes target area light and another area light. The collimator hole is used to obtain the target area light by screening and block the other area light. That is, the collimator hole screens the incident ambient light, and allows only the target area light to reach the infrared sensor.

Abstract: Method of processing objects by radio frequency (RF) energy. The method includes feeding, with a plurality of radiating elements, RF radiation into a cavity to process the objects in the cavity, receiving, with a plurality of dummy loads located outside of the cavity, RE energy coupled from the cavity into the radiating elements, and estimating an effect that operating at each of a plurality of sets of operating parameters will have on the temperature of each of the dummy loads. The method also includes, while maintaining the temperature of the dummy loads within a safe temperature range, choosing among the plurality of sets of operating parameters, at least one set based on the estimating and operating at the chosen at least one set of operating parameters.

Abstract: An unreleased thermopile IR sensor and method of fabrication is provided which includes a new thermally isolating material and an ultra-thin material based sensor which, in combination, provide excellent sensitivity without requiring a released membrane structure. The sensor is fabricated using a wafer transfer technique in which a substrate assembly comprising the substrate and new thermally isolating material is bonded to a carrier substrate assembly comprising a carrier substrate and the ultra-thin material, followed by removal of the carrier substrate. As such, temperature restrictions of the various materials are overcome.

Abstract: Embodiments disclosed herein provide an RTP system for processing a substrate. An RTP chamber has a radiation source configured to deliver radiation to a substrate disposed within a processing volume. One or more pyrometers are coupled to the chamber body opposite the radiation source. In one example, the radiation source is disposed below the substrate and the pyrometers are disposed above the substrate. In another example, the radiation source is disposed above the substrate and the pyrometers are disposed below the substrate. The substrate may be supported in varying manners configured to reduce physical contact between the substrate support and the substrate. An edge ring and shield are disposed within the processing volume and are configured to reduce or eliminate background radiation from interfering with the pyrometers. Additionally, an absorbing surface may be coupled to the chamber body to further reduce background radiation interference.

Abstract: Passive detector structures for imaging systems are provided, which are based on a coefficient of thermal expansion (CTE) framework. With such framework, a CTE-based passive detector structure includes a detector member that is configured to expand or contract in response to thermal heating resulting from photon exposure. The expanding/contracting CTE detector structure is configured to exert mechanical forces on resistor and/or capacitor circuit elements, which are part of an oscillator circuit, to vary the resistance and capacitance of such circuit elements and change a frequency or period of oscillation of an output signal of the oscillator circuit. The change in the frequency or period of oscillation of the output signal of the oscillator circuit is utilized to determine an amount of photon exposure of the CTE-based detector.

Abstract: A thermowell assembly for measuring a process temperature includes an elongate thermowell having a proximal end and a distal end. A bore extends between the two ends with the thermowell assembly configured to extend into a process fluid. An infrared sensor detects infrared radiation from the distal end through the bore of the thermowell and responsively provides a sensor output. A configuration is provided in which infrared radiation received by the infrared sensor from a wall of the bore is reduced and or radiation received from the distal end of the bore is increased.
