Abstract: An image processing apparatus includes at least one memory storing instructions, and at least one processor. The at least one processor is configured to execute the instructions to acquire image data of a predetermined space captured by a camera, set a mask region in the space, identify a person image being an image of a person included in the image data, estimate a body of the person, based on the person image, perform determination on whether the body of the person with respect to the person image is included in the mask region, perform processing of masking the person, based on a result of the determination by a determination means.

Abstract: An information processing apparatus (10) includes: an acquisition unit (11) that acquires information detected based on an image captured by an imaging apparatus (20); a determination unit (12) that performs a first determination process of determining to output a warning when a type of an object detected at time of start and end of a first period is a person, and a second determination process of determining to output a warning when behavior of the person detected based on the image continues for a second period or longer; and an output unit (13) that outputs the warning based on a result determined by the determination unit.

Abstract: A detection system 100 of the present invention includes a position detection means 121 for detecting position information representing a position of a predetermined part of a person and a position of an accessory in a specific shape held by the person, and a separation detection means 122 for detecting that the accessory is separated from the person based on the position information.

Abstract: The present invention provides a force sensor that is capable of detecting plastic deformation of a strain element. The force sensor detects components, in a plurality of directions, of a force exerted on the strain element. The force sensor includes: inspection strain gauges disposed in stress concentration areas of the strain element; and an inspection bridge circuit that includes the inspection strain gauges and that is configured to detect a component, in a specific direction, of a stress that occurs in the strain element.

Abstract: The present invention improves the reliability of a force sensor in terms of mechanical troubles. The force sensor includes: a primary bridge circuit that includes a first strain gauge group disposed on a first main face of a strain element and that is configured to detect a component, in a specific direction, of a force exerted on a strain element; and a secondary bridge circuit that includes a second strain gauge group disposed on a second main face of the strain element and that is configured to detect a component of a force in the same direction as the specific direction.

Abstract: The present invention achieves a force sensor in which an electrode, element, and/or the like connected to a strain gauge can be suitably attached to a strain element. The force sensor includes: a strain element including an arm portion that is deformable under an external force; and a strain gauge attached to the arm portion. The strain element includes a projection that sticks out from the arm portion in a direction intersecting the longitudinal direction of the arm portion.
