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: In a pulley apparatus, belt supporting portions of belt support pieces, which support a belt from a radially inside thereof, are arranged along a circumferential direction of a power shaft and each have a predetermined circumferential length. In a pulley driven mode, the belt support pieces rotate about corresponding first supporting members in a direction making the belt supporting portions become closer to the power shaft with second supporting members being relatively moved in corresponding elongated holes toward radially outer ends thereof, causing the belt supporting portions to be reduced in radius. In a pulley driving mode, the belt support pieces rotate about the corresponding first supporting members in a direction making the belt supporting portions become further from the power shaft with the second supporting members being relatively moved in the corresponding elongated holes toward radially inner ends thereof, causing the belt supporting portions to be increased in radius.

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: A starter for an engine is provided which includes an electromagnetic brake device and a pinion thrust mechanism. The electromagnetic brake device holds a planetary carrier from rotating. The pinion thrust mechanism converts rotational motion of an internal gear into linear motion of a pinion when the rotation of the planetary carrier is locked. The pinion thrust mechanism includes a cylindrical cam cylinder, a starter housing, a thrust collar rotatable relative to the pinion, and an engaging pin. The cam cylinder is joined to the internal gear and has a circumferential extending cam groove. The starter housing has a straight groove traversing the cam groove. The engaging pin engages both the cam groove and the straight groove and is moved linearly with rotation of the cam cylinder. This enables the linear movement of the pinion regardless of a helix angle of the spline mounted on the output shaft.

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 ejector includes a shaft coupled to a passage formation member defining a refrigerant passage inside a body, and the shaft is slidably supported by a support member fixed to the body. A drive mechanism moves the shaft in an axial direction to change a passage sectional area of the refrigerant passage. The passage formation member is provided with a vibration suppressive member including a first mobile end that applies a load to enlarge the refrigerant passage and a second mobile end that applies a load to narrow the refrigerant passage. Both the first mobile end and the second mobile end are disposed on a same side of a slide region of the support member in the axial direction.

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: In an ejector, formed in a body is a swirling space which lets a high-pressure refrigerant flowing from a refrigerant inlet port swirl and introduces the swirling high-pressure refrigerant into a depressurizing space in which the swirled high-pressure refrigerant is depressurized and expanded. A passage formation member that defines a nozzle passage and a diffuser passage is shaped to have a cross-sectional area increasing with distance from the depressurizing space. Further, a temperature sensing unit of a drive device that displaces the passage formation member is housed in the body, and the temperature sensing unit and a diaphragm have annular shapes to surround at least the axial line of the passage formation 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.
