Abstract: A training device including a motion data acquisition unit that acquires first motion data related to a target motion, a first generation unit that generates pseudo first motion data by using a first generation model, a determination unit that calculates a determination loss indicating a degree of deviation between the first motion data and the pseudo first motion data using a determination model, a relevance calculation unit that reconfigures the target motion by a combination of basis motions and calculate a degree of relevance between the target motion and the basis motions, a regularization loss calculation unit that calculates a regularization loss indicating a degree of deviation between motion data related to the basis motions and the pseudo first motion data, and an adversarial training processing unit that adversarially trains the first generation model and the determination model using the determination loss and the regularization loss.

Abstract: A data conversion device including a feature amount calculation unit that normalizes posture data estimated in each frame constituting moving image data including a synchronization target motion into an angular representation, and calculates a feature amount in an embedded space by inputting the posture data normalized into the angular representation to an encoder, a distance calculation unit that calculates a distance between a feature amount calculated in each frame constituting reference moving image data and a feature amount calculated in each frame constituting synchronization target moving image data, a synchronization processing unit that calculates an optimal path for each frame based on the calculated distance and synchronizes the synchronization target moving image data with the reference moving image data by aligning timings of frames connected by the optimal path, and an output unit that outputs the synchronization target moving image data synchronized with the reference moving image data.

Abstract: An activation system of a work machine includes a vehicle body control unit outputting a control signal to drive a vehicle body of the work machine with power supplied by a power source, and an authentication unit performing authentication of an operator of the work machine. The activation system of a work machine first activates the authentication unit, and activates the vehicle body control unit when the authentication unit authenticates that the operator boarding the work machine is a specific operator.

Abstract: A work machine start-up system includes a control unit configured to control a work machine, a proximity detection unit configured to detect that a specific operator is in close proximity to the work machine, and a start-up unit configured to start at least part of the control unit when it is detected that the specific operator is in close proximity to the work machine.

Abstract: An authentication unit performs authentication of an operator. A storage unit stores setting data associated with a plurality of operators. A vehicle body control unit outputs a control signal to drive a vehicle body of the work machine with power supplied by a power source, based on the setting data associated with the authenticated operator. The authentication unit receives the authentication when the power source is stopped and does not receive the authentication when the power source is driven.

Abstract: An image pickup apparatus includes a housing, an image sensor held by the housing, a lens frame that holds a plurality of lenses, and a connecting portion that connects the housing and the lens frame, and having an annular shape. The connecting portion includes a first portion provided to an inner surface of the connecting portion, and a second portion provided to an outer surface of the connecting portion. The first portion of the connecting portion engaged with an outer surface of the lens frame. The second portion of the connecting portion engaged with a first inner surface of the housing. The lens frame includes a first sliding portion engaged with the first inner surface of the housing and slidable in an optical axis direction of the plurality of lenses.

Abstract: An image pickup apparatus includes a sensor unit, a lens unit and a lens frame, a housing configured to hold the sensor unit and the lens unit, a connecting member that connects the lens frame and the housing, a cover member that covers part of a first lens disposed furthest to the image sensor, and an elastic member disposed between the first lens and the cover member. A thermal expansion coefficient of the connecting member is larger than that of each of the housing and the lens frame. The lens frame includes a first lens holding portion configured to hold the first lens. A connecting position between the connecting member and the lens frame is disposed on the image sensor side of each of a connecting position between the housing and the connecting member and a position of the first lens holding portion.

Abstract: A lens apparatus includes a lens unit and a fixed member engaged with the lens unit. A position of the lens unit relative to the fixed member is adjustable in an optical axis direction by rotating the lens unit relative to the fixed member about an optical axis. The lens unit includes a holding member configured to hold the lens and engaged with the fixed member, and a press member engaged with the holding member and configured to press the lens against the holding member in the optical axis direction. The holding member includes an engagement portion engageable with a tool configured to rotate the lens unit about the optical axis relative to the fixed member. The press member includes a hole portion penetrating in the optical axis direction. The hole portion enables the tool to be engaged with the engagement portion through the hole portion.

Abstract: An image pickup apparatus includes a sensor unit, a lens unit that includes a lens and a lens frame configured to hold the lens, a housing configured to hold the sensor unit and the lens unit, a cover portion configured to cover part of the lens, a first elastic body disposed between a groove portion provided in an outer diameter portion of the lens unit and an inner diameter portion of the housing, and a second elastic body disposed between the cover portion and the lens. In an optical axis direction, a first biasing force applied to the lens unit by the first elastic body acts in the same direction as a second biasing force applied to the lens unit by the second elastic body.

Abstract: An image pickup device of the present invention includes an image pickup element, an image pickup element holder that supports the image pickup element and is rotationally movable with respect to a plane orthogonal to an optical axis of an image pickup lens, an optical filter, and an optical filter holder that extractably supports the optical filter onto the optical axis of the image pickup lens. The optical filter holder rotationally moves along with a rotational movement of the image pickup element holder in an identical direction.
