A vibration-suppressed transformer is fixed to a base plate and includes a magnetic lower core, two or more magnetic upper cores, primary and secondary coils. The lower core is on the base plate. The upper cores are arranged face to face over the lower core. The coils are arranged between the lower and upper cores. Each upper core contacts the lower core, on an outer side of the coils, with a first gap being provided between the upper and lower cores, on an inner side of the coils. The upper cores are extended towards each other from the outer to the inner side of the coils, with a second gap being provided therebetween. The second gap is provided therein with a non-magnetic pressing member to press the lower core against the base plate, on an inner side of the coils.

Transformer incorporated in electronic circuits

A plurality of lighting units are positioned forwardly of the driver seat in the cabin of a vehicle for applying infrared radiations in respective directions to the vehicle driver seated on the driver seat. The intensities of the emitted infrared radiations are controlled according to respective basic controlled variables depending on the illuminance in the vehicle cabin. The position and orientation of the face of the vehicle driver are recognized from an image captured of the vehicle driver by an imaging device, and the basic controlled variables are corrected according to the recognized position and orientation, thereby adjusting the intensities of the infrared radiations emitted from the lighting units and a balance of the infrared radiations emitted from the lighting units. Thereafter, the illuminance in the vehicle cabin and the recognized position and orientation change, then corrective coefficients for the basic controlled variables are updated depending on the changes.

Vehicle cabin lighting apparatus

An apparatus for protecting an occupant in a vehicle includes a pair of image sensors for taking images of an area on a seat in the vehicle. Transverse-direction shifts between corresponding portions of the images are calculated. Longitudinal-direction positions of objects whose images are in the portions of the images taken by the image sensors are measured in response to the calculated transverse-direction shifts. A longitudinal-direction position of an occupant on the seat is decided in response to the measured longitudinal-direction positions of the objects. Occupant protecting operation at a time of occurrence of a collision of the vehicle is changed in response to the decided longitudinal-direction position of the occupant. From the measured longitudinal-direction positions of the objects, one corresponding to a highest position with respect to the vehicle and being in front of the seat is selected as a longitudinal-direction position of a head of the occupant.

Apparatus for protecting occupant in vehicle

A vehicular occupant restraint system includes a distance sensor, an electromagnetic wave radiation-type occupant sensor, a controller, and an airbag drive circuit. When the controller predicts a collision and determines it is unavoidable based on the output of the distance sensor, the controller sends an instruction signal to the occupant sensor to determine the seating condition of an occupant. Then, the airbag drive circuit performs an airbag deployment control in accordance with the determined seating condition. This system thus reduces power consumption and electromagnetic wave radiation of the occupant sensor.
