Abstract: Disclosed is a solar radiation sensor apparatus. A light-blocking plate is provided above the light-receiving surface of a photoelectric element, and has an area smaller than the area of the light-receiving surface. The incident angle sensitivity characteristic of the sensor apparatus can be improved without involving any increase in the external dimensions of the sensor apparatus.

Abstract: A building controller includes a controller that is operatively coupled to a motion sensor and provides one or more control signals based at least in part on the motion sensed by the motion sensor. A lens member includes a HDPE (high density polyethylene) lens and a lens mounting structure that includes a lens retention hook. A bracket defines an aperture in registration with the motion sensor and further defines a lens securement aperture configured to accommodate the lens retention hook. The bracket may also define a lens securement spring configured to provide a biasing force to the lens retention hook of the lens mounting structure.

Abstract: A photo-detection apparatus includes a light-shielding film, an optically-coupled layer, a photodetector, and an optical system. In the light-shielding film, light-transmitting regions and light-shielding regions are alternately arranged in at least a first direction within a plane. The optically-coupled layer faces the light-shielding film and includes a grating that propagates light in the first direction. The photodetector includes first photo-detection cells and second photo-detection cells arranged on an imaging area. The optical system is disposed between the optically-coupled layer and the photodetector. An image of light transmitted by parts of the optically-coupled layer that face each of the light-transmitting regions and light-shielding regions is enlarged or reduced by the optical system and formed on a corresponding one of the first and second photo-detection cells.
