Publication number: 20240122365Abstract: According to embodiments, an air mattress includes an air cell unit including an air cell, and a controller that controls an internal pressure in the air cell. The controller conducts a first operation when the internal pressure in the air cell satisfies the second condition after having satisfied a first condition. The first condition includes the internal pressure becoming from a first value to a second value lower than the first value, a difference between the first value and the second value being equal to or more than a first threshold, and a change rate relative to time of the internal pressure from the first value to the second value being equal to or more than a second threshold. The second condition includes, after the internal pressure has lowered from the first value to the second value, the internal pressure becoming a third value lower than the second value, and a difference between the second value and the third value being equal to or more than a third threshold.Type: ApplicationFiled: December 27, 2023Publication date: April 18, 2024Inventor: Kenta OHNO

Publication number: 20240077412Abstract: According to the embodiment, an optical imaging apparatus includes: an illuminator, a lens, an aperture, and an imaging element. Light is incident into the lens through an inspection object provided where the parallel light from the illuminator reaches. The light has passed through the solvent and the target, and/or through the solvent. The aperture is disposed on a focal plane of the lens. The aperture includes a passage region and a light-blocking region. The passage region allows passage of diffracted light in a direction different from a direction of the parallel light due to the target from the parallel light from the illuminator. The light-blocking region blocks the parallel light having passed through the solvent.Type: ApplicationFiled: February 27, 2023Publication date: March 7, 2024Applicant: KABUSHIKI KAISHA TOSHIBAInventors: Hiroya KANO, Hiroshi OHNO, Kenta TAKANASHI
