In an optical device, a lens assembly includes a lens for receiving light and a holder for holding the lens. A circuit board performs at least one process based on the received light. A housing has an opening and is configured to house the lens assembly and the circuit board therein such that at least part of the circuit board faces the lens assembly, and the lens assembly is exposed via the opening. A mechanism for defining a passage located around the lens assembly to communicate with the opening. The passage guides air, entering an inside of the housing via the opening, so as not to be directed toward the circuit board.

Optical device and imaging device with mechanism for reducing condensation

In a vehicular camera apparatus, at least one imaging unit captures an image of a region located outside a vehicle, and a first housing configured to install the at least one imaging unit thereto. A housing assembly includes a second housing configured as a separate member from the first housing, and includes a vehicle attachment provided to the second housing and attached to a part of the vehicle. The housing assembly is configured to fixedly support the first housing between the part of the vehicle and the second housing while the vehicle attachment is attached to the part of the vehicle.

Vehicular camera apparatus

An in-vehicle camera apparatus is provided for use in a vehicle. The in-vehicle camera apparatus includes at least one image capturing unit configured to capture an image of an external environment of the vehicle, at least one housing configured to have the at least one image capturing unit mounted thereto, and a mounting part via which the at least one housing is to be mounted to the vehicle. The mounting part is made of a material having a lower coefficient of linear expansion than the at least one housing. The mounting part has at least one first portion configured to be fixed to the vehicle and a plurality of second portions configured to be fixed to the at least one housing.

In-vehicle camera apparatus

A camera apparatus is provided. A bracket is fixed to a windshield of a vehicle. A camera case is fixed to the bracket. A camera module is fixed to the camera case and includes a lens. A hood intercepts light. When the camera apparatus is fixed to the vehicle, an inclination angle of an optical axis of the lens with respect to the camera case is adjusted so that an object present ahead of the vehicle is captured within an angle of view of the camera module. The camera apparatus detects a position of the object. The object includes a lane and another vehicle. Information on the object is used for lane departure alarm control, light control, or collision avoidance control. The type of the inclination angle of the optical axis with respect to the camera case or the type of a shape of the hood is visually displayed.

Camera apparatus

A camera apparatus is provided. A bracket is fixed to a windshield of a vehicle. A camera case is fixed to the bracket. A camera module is fixed to the camera case and includes a lens. The camera apparatus detects a position of an object present ahead of the vehicle. The object includes a lane and another vehicle. Information on the object acquired by the camera apparatus is used for at least one of lane departure alarm control, light control, and collision avoidance control. The camera apparatus further includes an adjustment structure for completing adjustment of an inclination angle in a vertical direction of an optical axis of the lens with respect to the windshield by the time when the camera case is completely fixed to the bracket.

Windshield-mounted camera apparatus and adjuster

A camera module captures an image of an area ahead of a vehicle. A control circuit board performs a recognition process to recognize conditions ahead of the vehicle, and performs at least two vehicle control processes from among a lane departure warning process, a headlight control process, and a forward collision avoidance process. A housing accommodates the camera module and the control circuit board. A bracket fixes the housing to the windshield of the vehicle, and has an opening permitting the housing and the windshield to face each other in a state where the housing is fixed to the windshield via the bracket. A hood covers the camera module. A first thermally conductive member is provided being in contact with the housing and the windshield in the opening formed on the bracket.

In-vehicle camera device and in-vehicle system

A capacitance type sensor installed in a vehicle includes the first electrode, the second electrode, and the third electrode. The first electrode is arranged inside a seating portion of a seat or a backrest portion of the seat, or both. The second electrode is arranged adjacent to the first electrode inside at least one of the seating portion and the backrest portion of the seat, whatever the first electrode is arranged. The second electrode forms an electric field together with the first electrode between them in a wetness determination mode in which a wet condition of the seat is determined. The third electrode forms an electric field together with the first and the second electrode between them in an occupant determination mode in which an occupant in the seat is determined.

Capacitance type sensor and occupant detection system having the same

A capacitance-type sensor for detecting a condition of an occupant on a vehicle seat includes an electrode. The electrode is disposed within a detection area in the vehicle seat. The electrode generates an electric field. The detection area is based on a surface pressure distribution obtained when an adult sits on the seat.

Capacitance-type sensor and occupant detection system

A seatbelt alarm device for a vehicle includes a seat sensor, a seatbelt sensor, a judgment circuit, an alarm unit, and a child seat sensor. The seat sensor detects a mass on a seat of the vehicle. The seatbelt sensor detects whether a seatbelt of the seat is engaged with a seatbelt buckle. The judgment circuit generates a demand for a seatbelt-wear alarm upon determining that a mass sits on the seat and the seatbelt is not engaged according to detection signals of the seat sensor and the seatbelt sensor, respectively. The alarm unit generates the seatbelt-wear alarm. The child seat sensor detects a child seat mounted on the seat. The judgment circuit restricts operation of the alarm unit when the judgment circuit determines that the child seat is mounted to the seat according to a detection signal of the child seat sensor.

Seatbelt alarm device for vehicle

A rotation angle detecting device includes a columnar permanent magnet that has a generally ring-shaped cross-section and a pair of magnetic poles, a pair of semi-cylindrical yokes disposed in a circumferential direction opposite the permanent magnet, a rotary shaft fixed to the permanent magnet at a shifted rotation axis and a magnetic sensor disposed in one of circumferential gaps between the yokes. The rotation axis and the magnetic poles are arranged so that the magnetic flux density becomes maximum at portions of the yoke less than 90 degrees angled from the circumferential gap in which the magnetic sensor is disposed.
