摘要： An optical fiber is optically coupled to a light-receiving/emitting element contained in an interface box. The coupling structure is composed of a cylindrical ferule water-tightly inserted into a through-hole formed in a wall of the interface box, a resilient grommet coupled to the ferule and a coupler having the light-receiving/emitting element. An optical fiber is inserted into coaxially formed center holes of the ferule and the grommet, and an axial end of the optical fiber is exposed at an axial end of the ferule. The coupler is coupled to the ferule so that the light-receiving/emitting element directly faces the exposed end of the optical fiber to establish an optical connection at a minimized connection loss.

摘要： A satellite sensor and a floor sensor are provided in a forward portion and a central portion, respectively, of a vehicle body. A calculated value and a speed are determined through predetermined processing of a deceleration detected based on an output signal of the floor sensor. If a value determined from the relationship between the calculated value and the speed exceeds a predetermined threshold changing pattern, an airbag apparatus is activated. The threshold changing pattern is set by selecting a map from a Hi map, a Lo1 map, a Lo2 map and a Lo3 map based on a deceleration determined from an output signal of the satellite sensor. If a map different from the current map is to be set as a threshold changing pattern, the threshold changing pattern is set to the desired map after a state that allows the map to be set continues for a time corresponding to a difference between the two maps.

摘要： An activation control apparatus controls activation of an airbag unit. An electronic control unit detects a floor deceleration Gf and front decelerations GI, Gr from signals output from a floor sensor and front sensors. Also, the electronic control unit calculates a velocity change Vn from the floor deceleration Gf, and determines the severity of a collision. Further, the electronic control unit determines the state of a symmetric flag FRG through comparison between the front decelerations GI, Gr and the value of a front determination map boundary, serving as a front threshold variation pattern and through comparison between the floor deceleration Gf and the value of a low or high map boundary, serving as an activation threshold variation pattern. Then, on the basis of results of the severity determination and the state of the symmetric flag FRG, the electronic control unit determines a delay time in relation to the activation of the airbag unit. An airbag is expanded and deployed on the basis of the delay time.

摘要： A collision severity determining system for determining severity of a collision of a vehicle includes a first deceleration detector disposed in a central portion of a vehicle for detecting a deceleration in a longitudinal direction of the vehicle, and a second deceleration detector disposed in a front portion of the vehicle for detecting a deceleration in the longitudinal direction. A controller calculates a velocity change amount of the vehicle by integrating the vehicle deceleration with respect to time, and determines severity of the collision by comparing the vehicle deceleration with a threshold value corresponding to the same velocity change amount. When a problem, such as a failure or breakdown of the second deceleration detector, occurs, the severity determining unit operates in a predetermined fail-safe mode for selecting an appropriate severity determination map stored in the controller, and makes a severity determination based on the selected severity determination map.
