Abstract: A power circuit breaker has a housing defining a first passage and a cross passage through the housing. A bus bar extends through the cross passage and is configured to transmit electric power and/or break transmission of the electric power through the housing. The bus bar includes at least an input section, a coin or center section, and an output section that are separable from each other. The housing aligns a solenoid piston within the first passage of the housing. The solenoid has a piston with two opposite ends, and one of the ends operates as a plunger to separate the sections of the bus bar when the solenoid is actuated. The plunger moves the coin or center section of the bus bar out of contact with the input section and the output section of the bus bar to break electrical transmission across the bus bar.

Abstract: A system (10) for helping to protect an occupant of a vehicle (12) includes a vehicle occupant protection device (20). An event sensor (14) is operative to sense a vehicle event condition such as a vehicle crash or rollover and provides a vehicle event condition signal (22) indicative of the sensed vehicle condition. A vehicle operating condition sensor (18) senses vehicle operation conditions such as ignition starts, vehicle speed, etc. A controller (16) is operative to determine the occurrence of a vehicle event in response to the vehicle condition signal (22). The controller (16) is operative to provide an actuation signal (24) for actuating the vehicle occupant protection device (20) in response to determining the occurrence of the vehicle event. A software key (100) is provided having a disable mode (106) in which the controller (16) is inhibited from providing the actuation signal (24). The software key is responsive to the signals from the vehicle operating sensors (18).

Abstract: A vehicle occupant protection apparatus (10) includes an occupant protection device (20), such as an air bag module, that is actuatable for protecting a vehicle occupant (14). The protection device (20) has first and second stages (44 and 46). A first driver (38) actuates the first stage (44) of the protection device (20) and a second driver (42) actuates the second stage (46) of the protection device. An enable arrangement (64) is responsive to actuation of the first stage (44) of the protection device (20) to enable the actuation of the second stage (46) of the protection device (20).
