Abstract: A method for manufacturing a detection device includes steps of: producing thermal detectors distributed in a detection array and a compensation array using mineral sacrificial layers; producing an encapsulation structure comprising a thin opaque layer extending above the compensation array; partially removing the mineral sacrificial layers by chemical etching, so as to release the detection array and the compensation array, and to obtain the peripheral wall then formed of a non-etched portion of the mineral sacrificial layers and surrounding the compensation array, the thin opaque layer then being suspended above the compensation array and resting on the peripheral wall.

Abstract: Current signals indicative of sensed physical quantities are collected from sensing transistors in an array of sensing transistors. The sensing transistors have respective control nodes and current channel paths therethrough between respective first nodes and a second node common to the sensing transistors. A bias voltage level is applied to the respective first nodes of the sensing transistors in the array and one sensing transistor in the array of sensing transistors is selected. The selected sensing transistor is decoupled from the bias voltage level, while the remaining sensing transistors in the array of sensing transistors maintain coupling to the bias voltage level. The respective first node of the selected sensing transistor in the array of sensing transistors is coupled to an output node, and an output current signal is collected from the output node.

Abstract: A reference element of an infrared sensor includes a substrate, a sacrificial layer, a supporting structure, a fence structure and an infrared sensing structure. The sacrificial layer is disposed on the substrate. The supporting structure is disposed on the substrate wherein the top surface of the supporting structure is coplanar with the top surface of the sacrificial layer. The fence structure is disposed on the substrate and surrounds the sacrificial layer wherein the top surface of the fence structure is coplanar with the top surface of the sacrificial layer, and there is an air gap between the fence structure and the supporting structure. The infrared sensing structure is disposed on the sacrificial layer, the supporting structure and the fence structure, and the infrared sensing structure has an opening corresponding to the air gap.

Abstract: Devices and corresponding methods can be provided to monitor or measure temperature of a target or to control a process. Targets can have low, unknown, or variable emissivity. Devices and corresponding methods can be used to measure temperatures of thin film, partially transparent, or opaque targets, as well as targets not filling a sensor's field of view. Temperature measurements can be made independent of emissivity of a target surface by, for example, inserting a target between a thermopile sensor and a background surface maintained at substantially the same temperature as the thermopile sensor. In embodiment devices and methods, a sensor temperature can be controlled to match a target temperature by minimizing or zeroing a net heat flux at the sensor, as derived from a sensor output signal. Alternatively, a target temperature can be controlled to minimize the heat flux.

Abstract: The present disclosure relates to the technical field of temperature measuring guns and discloses a temperature measuring gun base charging structure and a temperature measuring gun applying the same. The temperature measuring gun base charging structure includes a base, a base bottom is integrally formed on a lower side of the base, a placement cavity is formed in one side of an upper portion of the base, base side walls are arranged on other side surfaces of the base, a charging module is arranged in the placement cavity, and a charging cable extends out of the base bottom. By arranging the placement cavity with an oblique inner wall, a lower end of the temperature measuring gun may be placed in the placement cavity, and the temperature measuring gun is placed obliquely and uprightly, which is not prone to falling and convenient to take for use.

Abstract: Techniques are provided for facilitating detection threshold determination for infrared imaging systems and methods. In one example, a method includes capturing, by an imaging device, a thermal image of a scene. The method further includes determining temperature difference data indicative of a difference between temperature data of the thermal image associated with a background of the scene and temperature data of the thermal image associated with gas detection. The method further includes determining detection threshold data based on sensitivity characteristics associated with the imaging device and the temperature difference data. The method further includes generating a detection threshold image based on the detection threshold data. Each pixel of the detection threshold image corresponds to a respective pixel of the thermal image and has a value indicative of a detection threshold associated with the respective pixel of the thermal image. Related devices and systems are also provided.

Abstract: The present invention relates to an arrangement (1) for measuring the temperature of a web. The arrangement (1) comprises a plurality of sensors (3) for contactless measuring of the temperature, an elongated housing (5) intended for extending essentially along a transverse direction (T) which is transverse to the direction of movement of a web. The sensors (3) are arranged in a chamber (6) within the housing (5) and spread along the front side (7a) of the housing (5). Each sensor (3) is connected to a data bus (9) for providing information of the measured temperature to other systems and/or apparatuses. The sensors (3) are attached to a support structure (19) having at least one rotatable shaft (23) in the interior of the housing (7), and wherein the shaft (23) is arranged to rotate the support structure (19) such that the sensors (3) are displaced to a calibration and/or protection position away from the openings (11) for calibration and/or protection of the sensors (3). The invention also relates to a method for measuring the temperature of a web, a computer program, a computer readable medium and a control unit.
