Abstract: An automotive vehicle includes a vehicle body and at least one reservoir containing a fire suppressant agent. A distribution system receives the fire suppression agent from the reservoir and conducts the agent to at least one location about the vehicle's body in response to the determination by a sensor system and controller that the vehicle has been subjected to a significant impact. The sensor system and controller determine not only the magnitude of an impact upon the vehicle, but also track subsequent motion of the vehicle, as well as the time which has elapsed since an impact, so as to decide if and when the fire suppressant agent should be dispersed. Alternatively, the fire suppressant agent may be dispersed following activation of a manual switch.

Abstract: In an automatic transmission system, a position sensor provides digital and analog output indications of the sensed position of a manually operated transmission gear shift lever. Electrical contacts within the sensor are configured to minimize wear and corrosion by eliminating electrical continuity in the switching elements when the gear shift lever is in the Drive position.

Abstract: Sensors (170, 172) for sensing articulation angle (AA) and/or a time derivative thereof (dAA/dt, d.sup.2 AA/dt.sup.2) for a trailer anti-swing control system are provided. In the preferred embodiments, at least the active transducers of the sensors are mounted to the tractor (12) subvehicle of the articulated vehicle system (10).

Abstract: A dual speed sensor pickup assembly (140) for sensing the rotational velocity of two independently rotatable, closely axially spaced exciter rotors (116 and 118) is provided. The pickup assembly includes two speed sensor assemblies (136 and 138) each including a pole piece (152,160) having a longitudianl axis (152a,160a) with the longitudinal axes skewed relative to one another but radial relative to the common axes of rotation (24) of the exciter rotors. Each speed sensor includes a permanent magnet (154,162) disposed between an end of the pole piece (152,160) and having a face divided into first and second surface (154a,154b and 162a,162b) by a slot (154c,162c) therein. In one embodiment a primary coil (156,164) and a secondary or anti-cross talk coil (158,166) surrounds the pole piece of each sensor (136,138), and each secondary coil is conductively connected to the primary coil of the other sensor.

Applications include drive axles and antilock brakes.

Abstract: An in-axle wheel speed sensor exciter rotor assembly (100) for sensing the rotational speeds of a drive axle ring gear (14/30) and a drive axle differential side gear (48) is provided. The assembly includes a tubular member (102) having teeth (110) for engagement with slots (112) provided on the side gear hub (48a) and carrying a first exciter rotor (116) at the opposite end (114) thereof. A second exciter rotor (118) is axially retained on the tubular member axially adjacent the first exciter rotor and is rotatable relative thereto. The second exciter rotor carries a coupling device (124/128) for engagement with threaded bores (126) provided in the drive axle ring gear/carrier assembly to rotationally couple the second exciter rotor to the ring gear and to axially retain the assembly (100) within the drive axle.
