Abstract:
A photosensor of the present disclosure includes: a first electrode; a second electrode; a photoelectric conversion layer located between the first electrode and the second electrode, the photoelectric conversion layer generating electric charges by photoelectric conversion; a first charge blocking layer located between the first electrode and the photoelectric conversion layer; a second charge blocking layer located between the second electrode and the photoelectric conversion layer; a voltage supply circuit that applies voltage to at least one of the first electrode and the second electrode such that an electric field directed from the second electrode toward the first electrode is generated in the photoelectric conversion layer; and a detection circuit that detects a signal corresponding to a change in capacitance between the first electrode and the second electrode, the change in capacitance being caused by incident light to the photoelectric conversion layer. The first charge blocking layer is configured to suppress movement of holes from the photoelectric conversion layer to the first electrode and movement of electrons from the first electrode to the photoelectric conversion layer. The second charge blocking layer is configured to suppress movement of electrons from the photoelectric conversion layer to the second electrode and movement of holes from the second electrode to the photoelectric conversion layer.

A contactless temperature sensor for copper wires in movement, comprising a body of the sensor (12) which provides an insulated sealed cavity (19) wherein an insulated cavity (21,22) is provided inside the sealed cavity, having an axial development and with a sensitive element in the centre made of a material having a high thermal diffusion (11), a pyrometer (16) being positioned in the sensor body (12), which extends inside the sealed cavity (19) and faces the sensitive element with a high thermal diffusion (11).
Abstract:
This relates to sensor systems, detectors, imagers, and readout integrated circuits (ROICs) configured to selectively detect one or more frequencies or polarizations of light, capable of operating with a wide dynamic range, or any combination thereof. In some examples, the detector can include one or more light absorbers; the patterns and/or properties of a light absorber can be configured based on the desired measurement wavelength range and/or polarization direction. In some examples, the detector can comprise a plurality of at least partially overlapping light absorbers for enhanced dynamic range detection. In some examples, the detector can be capable of electrostatic tuning for one or more flux levels by varying the response time or sensitivity to account for various flux levels. In some examples, the ROIC can be capable of dynamically adjusting at least one of the frame rate integrating capacitance, and power of the illumination source.

Abstract:
In one embodiment, A MEMS sensor assembly includes a substrate, a first sensor supported by the substrate and including a first absorber spaced apart from the substrate, and a second sensor supported by the substrate and including (i) a second absorber spaced apart from the substrate, and (ii) at least one thermal shorting portion integrally formed with the second absorber and extending downwardly from the second absorber to the substrate thereby thermally shorting the second absorber to the substrate.
Abstract:
A heat sensing module for a heat alarm apparatus comprises a base section having a concave surface, protection means, a heat sensor, and a control circuit configured to detect a temperature rise at the heat sensor and output an alarm signal in response thereto. A sensing part of the heat sensor is located in a space formed between the concave surface of the base section and the protection means. The concave surface assists with reflecting, radiating and absorbing heat, thereby increasing the speed at which the heat sensor registers a change in temperature.
Abstract:
The device for detecting electromagnetic radiation comprises, on one and the same substrate (18): at least one active detector (7) for detecting the electromagnetic radiation (8), the detector being equipped with a first element (12) able to sense said radiation (8); at least one reference detector (10) comprising a second element (13) able to sense said electromagnetic radiation (8); and a shield (19) equipped with first reflective means for reflecting the incident electromagnetic radiation (8), said shield (19) covering the second sensing element (13) without making contact with it, and defining, with the substrate (18), a cavity (20) in which the reference detector (10) is housed. The shield (19) is conformal in order to improve the sensitivity of the detection device.
