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.

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.

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 actuator capable of attaining high output. The actuator includes a frame structure part that forms a frame structure surrounding a housing part, and a volume change part housed in the housing part. The volume change part increases a volume thereof by input of external energy. The frame structure part has a higher Young's modulus than a Young's modulus of the volume change part. The housing part has an anisotropic shape, with a maximum width in first direction of the housing part longer than a maximum width in second direction different from the first direction of the housing part.

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: An occupant detection system includes a state detection unit that detects a state of an object, a detection position changing unit that changes a position of a detection region, the detection region being a region in which state is detected by the state detection unit, and a controller that controls an operation of the detection position changing unit. In this occupant detection system, a position of the detection region is set to a predetermined initial position during a period of time from when a start switch provided in the vehicle is turned off until when the start switch is turned on.
