    Abstract: An occupant detection system may detect a state of an occupant in a vehicle compartment. The occupant detection system may photograph the vehicle compartment and generate an image. The occupant detection system may change an attitude in order to change a position of an imaging region within the vehicle compartment. The occupant detection system may estimate the attitude based on information included in the image and control an operation based on the estimated attitude. The sensor may be provided by an infrared temperature sensor. The image may be provided by a thermal image showing a temperature distribution of the vehicle compartment. The occupant detection system may store a correspondence relationship between a position of a specific temperature boundary included in the thermal image and the attitude. The occupant detection system may estimate the attitude based on the correspondence relationship.

    Abstract: An object recognition device includes a first sensor that acquires an image of an object present outside a movable body, a second sensor that detects a distance to the object, and a recognition unit that recognizes a position of the object with respect to the movable body and a shape of the object at the position by using outputs from the first sensor and the second sensor. If determining that the object is a first type object having a size equal to or more than a predetermined size, the recognition unit determines an actual shape of the object based on an image of the object acquired by the first sensor and the distance detected by the second sensor, and recognizes that the object is present as the actual shape at a position distanced from the movable body by the distance.

    Abstract: An actuator device includes an actuator member, a drive subject, a first drive device and a second drive device. The actuator member is configured to be deformed in response to application of energy to the actuator member from an outside. The drive subject is coupled to the actuator member. The first drive device is configured to apply the energy to the actuator member and thereby displace the drive subject in a deforming direction of the actuator member. The second drive device is configured to displace the drive subject in a different direction that is different from the deforming direction of the actuator member.

    CPC classification number: H02N10/00

    Abstract: An actuator device includes an actuator member, a drive subject, a drive device, and a tension applicator. The actuator member is configured to be deformed in response to application of energy to the actuator member from an outside of the actuator member. The drive subject is coupled to the actuator member. The drive device is configured to apply the energy to the actuator member and thereby displace the drive subject in a deforming direction of the actuator member. The tension applicator is configured to apply the actuator member a tension, which enables correction of a tension change generated by at least one of elongation and contraction of the actuator member that is induced by natural deformation of the actuator member.

    Abstract: A movable device includes an actuator element that deforms about an actuator axis in response to increase or decrease in energy of the actuator element. A driven body is coupled to the actuator element on the actuator axis and turned by deformation of the actuator element. A guide mechanism guides turning of the driven body about a turning axis coaxial with the actuator axis such that torsional deformation of the actuator element is directly transferred to the turning of the driven body.

    Abstract: An actuator that comprises a deformable material, an energy input part, and a characteristics change detection unit. The deformable material is configured with a polymer fiber and, by deforming in response to energy input from the outside, outputs motive power. The energy input part inputs energy to the deformable material. The characteristics change detection unit detects when the deformation characteristic of the deformable material has changed. The actuator also comprises a drive control unit that, by controlling the above-described energy, controls the output of the deformable material. When the characteristic change detection unit detects a change in the deformation characteristic, the drive control unit controls the energy in accordance with the change in the deformation characteristic.
