Patent number: 11768148Abstract: A particle detector formed by a body defining a chamber and housing a light source and a photodetector. A reflecting surface is formed by a first reflecting region and a second reflecting region that have a respective curved shape. The curved shapes are chosen from among portions of ellipsoidal, paraboloidal, and spherical surfaces. The first reflecting region faces the light source and the second reflecting region faces the photodetector. The first reflecting region has an own first focus, and the second reflecting region has an own first focus. The first focus of the first reflecting region is arranged in an active volume of the body, designed for detecting particles, and the photodetector is arranged on the first focus of the second reflecting region.Type: GrantFiled: July 2, 2021Date of Patent: September 26, 2023Assignee: STMICROELECTRONICS S.r.l.Inventors: Antonello Santangelo, Salvatore Cascino, Viviana Cerantonio

Patent number: 11686673Abstract: The device is formed in a casing including a support, a spacer body, and a mirror element fixed together. A light-emitting element and a light-receiving element are arranged on a bearing surface of the support and face a reflecting surface of the mirror element. The light-emitting element is configured to generate infrared radiation, and the light-receiving element is configured to receive light radiation reflected by the reflecting surface. The spacer body has an emission opening housing the light-emitting element and a reception opening housing the light-receiving element; the reception opening comprises a radiation-limitation portion configured to enable entry of reflected light radiation having an angle, with respect to a normal to the bearing surface, of less than a preset value.Type: GrantFiled: March 30, 2021Date of Patent: June 27, 2023Assignee: STMICROELECTRONICS S.r.l.Inventors: Maria Eloisa Castagna, Salvatore Cascino, Viviana Cerantonio, Antonello Santangelo
