Abstract: The product inspection system comprises an inspection information collecting unit which collects inspection information acquired from an inspection target, an inspection time acquisition unit which acquires an inspection time that the inspection information was acquired, a recording unit which mutually associates and records the inspection information collected by the inspection information collecting unit and the inspection time acquired by the inspection time acquisition unit, and a display control unit which displays the inspection information recorded in the recording unit on a display terminal.

Abstract: Provided is a digitalization system capable of digitalizing the skills of delicate work. This digitalization system comprises a first sensor mounted on a work tool and which detects a deformation of the work tool when the work tool is pressed against a work target, a second sensor which detects a force applied to the work target or a force applied to the work tool when the work tool is pressed against the work target, and a computer which calculates an angle of a corner formed with the work tool and the work target based on sensor values acquired with the first sensor, and calculates a force applied to the work target when the work tool is pressed against the work target based on sensor values acquired with the second sensor.

Abstract: To accurately recognize observed objects.
An observed-object recognition system includes an observation region estimation portion, an existence region estimation portion, and an object recognition portion. The observation region estimation portion estimates an observation region that is relatively highly likely to be an observation point in at least one first-person image in a first-person video (a video based on the first-person perspective). Based on the observation region, the existence region estimation portion estimates an existence region that belongs to the first-person image and causes an observed object to exist. The object recognition portion recognizes an object in the estimated existence region of the first-person image.

Abstract: A pressure sensor device, a method for manufacturing the pressure sensor device, and a work management system mitigating a degree of a false detection is presented. The pressure sensor device detecting pressure includes a flexible substrate base material having flexibility; a comb-teeth shape electrode having an exposed metal surface formed in a predetermined area on the flexible substrate base material; and a pressure-sensitive material that is provided on the comb-teeth shape electrode, varies in a resistance value depending on an amount of a load, and has a curvature in a static state.
