Abstract: A passenger detection system is presented so that the master control circuit in the system instructs the passenger airbag control circuit controlling the operation of the airbag designated for the passenger seat to be in the deployable state or not-deployable state, depending on the seating conditions of a passenger sitting on the passenger seat, for example whether the passenger is an adult or a child.

Abstract: A vehicle area detector correctly detects a vehicle area. The vehicle area detector detects a vehicle area in a vehicle candidate area having a high probability of existence of a vehicle in an image produced by imaging means mounted on a vehicle.

Abstract: Control method for an electric power steering apparatus feeds back a motor current, flowing through a motor whose operation is controlled in accordance with a target motor current, so that the driving of the motor is controlled with the fed-back motor current. Peak value of the motor current is detected, and, for feedback control based on the detected peak value, the detected peak value is corrected to decrease. The thus-corrected peak value is fed back to control the motor current to conform to a target motor current value.

Abstract: In an occupant detecting apparatus for detecting an occupant seated on a passenger seat of a vehicle with an airbag for the occupant, a load sensor is provided in a bottom part of the seat. A plurality of first electric field sensors are provided in the bottom part of the seat, and a plurality of second electric field sensors are provided in a rear part of the seat. An airbag inflating permission control unit permits inflation of the airbag in accordance with output signals of the load sensor and the first and second electric field sensors.

Abstract: A high-frequency module of the present invention includes a laminate ceramic layer including a first layer smaller in area than the other layers. Parts constituting high-frequency circuitry are mounted on the laminate ceramic layer. A single interface substrate is juxtaposed to the first layer and connects the high-frequency circuitry and a waveguide. A metallic casing supports the laminate ceramic substrate and interface substrate with ground held in contact. The metallic casing is formed with at least one waveguide hole. A cover covers the waveguide hole and forms a waveguide end cavity. The interface substrate is positioned on the second layer of the laminate ceramic substrate, which just underlies the first layer, at one side and protrudes from the metallic casing into the waveguide hole at the other side.

Abstract: An arithmetic and control unit includes a monitor unit which counts a cycle time by receiving diagnostic pulses and generates an overflow bit that takes on a prescribed state value when it decides that the cycle time is larger than a prescribed overflow decision time and outputs it after a lapse of a prescribed time, and outputs a pulse-form reset signal as an active level during a prescribed time when the overflow bit is a prescribed state value. Also included is a control unit which generates a diagnostic pulse at every execution of a unit control during control operation and is reactivated upon receipt of active level of a reset signal, and receives and stores the overflow bit at every activation including a reactivation.
