A communication apparatus includes a first antenna array with plurality of antenna elements multiple antenna elements and first plurality of thermoelectric devices distributed across the plurality of antenna elements. An activation or a deactivation of each thermoelectric device is executed in a real-time or near real-time based on an operational state of each antenna element of the plurality of antenna elements and a performance state of the plurality of antenna elements, where the activation or the deactivation is performed in a defined delayed time after a defined time has elapsed from a start of operation of the first antenna array to mitigate performance degradation of the plurality of antenna elements when in operation. Adaptive cooling is applied by each thermoelectric device on different subsets of antenna elements such that performance breakdowns due to heating of a plurality of chips associated with the different subsets of antenna elements is reduced.

We disclose herein a thermal IR detector array device comprising a dielectric membrane, supported by a substrate, the membrane having an array of IR detectors, where the array size is at least 3 by 3 or larger, and there are tracks embedded within the membrane layers to separate each element of the array, the tracks also acting as heatsinks and/or cold junction regions.
Abstract:
We disclose an array of Infra-Red (IR) detectors comprising at least one dielectric membrane formed on a semiconductor substrate comprising an etched portion; at least two IR detectors, and at least one patterned layer formed within or on one or both sides of the said dielectric membrane for controlling the IR absorption of at least one of the IR detectors. The patterned layer comprises laterally spaced structures.
Abstract:
Nanoscale thermocouples are made of a single material and are shape-engineered to contain one or more variations in their width along their length. The mono-metallic nanowire junctions resulting from the width variation(s) exploit a difference in the Seebeck coefficient that is present at these size scales. Such devices have a wide variety of uses and can be coupled with an antenna in order to serve as an infrared detector.
Abstract:
A controller comprising: an output for controlling one or more outdoor lighting device to illuminate an outdoor environment; an input for receiving temperature information from a temperature sensor comprising a plurality of temperature sensing elements; and a control module. The control module is configured to: use the temperature information received from the temperature sensor to detect motion in a sensing region of the temperature sensor and control the one or more lighting device based on the detected motion, and additionally use the temperature information received from the temperature sensor to detect conditions of the environment in the sensing region and further control the one or more lighting device based on the detected conditions.
Abstract:
An infrared camera system is provided to detect absorption of infrared radiation in a selected spectral bandwidth. In one example, an infrared camera system includes a lens adapted to receive infrared radiation from a survey scene comprising one or more gasses. The infrared camera system also includes a focal plane array comprising a plurality of quantum well infrared photo detectors (QWIPs). The QWIPs are tuned to detect a limited spectral bandwidth of the infrared radiation corresponding to at least a portion of an infrared absorption band of the one or more gasses. The infrared camera system also includes an optical band pass filter positioned substantially between the lens and the focal plane array. The optical band pass filter is adapted to filter the infrared radiation to a wavelength range substantially corresponding to the limited spectral bandwidth of the QWIPs before the infrared radiation is received by the focal plane array.
Abstract:
A fixing device includes a fixing rotator and a pressure rotator contacting the fixing rotator to form a fixing nip therebetween, through which recording media of a plurality of sizes are conveyed. The recording media create a plurality of non-conveyance spans on a lateral end of the fixing rotator in an axial direction thereof where the recording media are not conveyed. A heater is disposed opposite the fixing rotator to heat the fixing rotator. A multi-view thermopile array is disposed opposite an outer circumferential surface of the lateral end of the fixing rotator in the axial direction thereof and angled relative to the fixing rotator to detect a temperature of the fixing rotator. The thermopile array includes an inboard temperature detection element directed to a conveyance span on the fixing rotator where the recording medium of a decreased size is conveyed.
