Patent number: 11892355Abstract: An optical device designed to be arranged on a detector provided with an infrared sensor for increasing the angle of the field of view of the detector. The device includes a primary mirror and a secondary mirror that face each other. The primary mirror collects the infrared radiation from a wide-angle field of view to return it to the secondary mirror, which in turn reflects it back to the sensor of the infrared detector.Type: GrantFiled: January 8, 2020Date of Patent: February 6, 2024Assignee: CENTRE SCIENTIFIQUE ET TECHNIQUE DU BÂTIMENT (CSTB)Inventors: Christophe Martinsons, Pierre Lepretre

Patent number: 11596144Abstract: A method of detecting the presence of insects, including larvae, in an indoor environment, which includes the steps of (a) obtaining a sample of volatile organic compounds (VOCs); (b) separating the sampled VOCs; (c) detecting the presence or absence of “target” VOCs from at least one category: “category 1 VOCs”—VOCs emitted independently of the support on which the insects develop and emitted only in an insect infestation VOCs, “category 2 VOCs”—VOCs emitted independently of the support but may have biological origins other than insects, and “category 3 VOCs”—VOCs emitted depending on the support and emitted only in an insect infestation; (d) calculating both an insect infestation index (“3I”) and a limit value (“VL”) based on the presence or absence of the target VOCs; and (e) comparing the “3I” and “VL” values. The environment is infested for a “3I” value strictly greater than the “VL” value.Type: GrantFiled: December 21, 2018Date of Patent: March 7, 2023Assignee: CENTRE SCIENTIFIQUE ET TECHNIQUE DU BATIMENT (CSTB)Inventors: Isabelle Lacaze, Stéphane Moularat, Enric Robine
