摘要： A vehicle crash event is detected and characterized based on the transmission of acoustical shear waves through the vehicle frame. At least three, and preferably four or more, acoustical emission sensors longitudinally and laterally distributed on the vehicle frame produce acoustical signals that are processed to extract the shear wave energy due to impacts. Since shear waves are non-dispersive and travel through the vehicle frame at a known velocity, they can be detected in any part of the frame. The extracted shear wave signals are used not only to judge the severity of the impact, but also to characterize the type of crash and determine the direction of the impact based on when the shear wave is detected by each of the acoustical emission sensors.

摘要： The capacitance of a shielded capacitive load cell is determined so as to minimize the effect of stray or parasitic capacitance between the load cell and other objects including the shield. The load cell conductors are coupled across input and output terminals of an operational amplifier that is tied to a reference voltage. A constant current is applied to the load cell, and the resulting rate of change in voltage at the amplifier output is measured as a representation of the load cell capacitance. In a vehicle seat sensor application including an electromagnetic interference shield between the load cell and the seating surface, the amplifier output is coupled to the load cell electrode furthest from the shield, the amplifier maintains the other load cell electrode at a virtual reference voltage, and the shield is tied to the reference voltage.

摘要： An ultrasonic occupant detection and classification system transmits an ultrasonic signal and receives a composite signal containing interference created between the transmitted ultrasonic signal and a reflection of that signal from a moving occupant. A signal component of the received, composite signal is extracted by amplitude demodulation and bandpass filtered to derive a frequency characteristic that is compared to stored frequency data; and the derived and stored data are compared to identify frequencies characteristic of respiration and/or other movements characteristic of living beings.

摘要： An improved infrared occupant detection system that provides accurate and reliable occupant intrusion information at a speed sufficient to timely inhibit or otherwise control deployment of occupant restraints. An array of infrared emitters is selectively activated to emit a predetermined pattern of IR beams in an area between the passenger seat and the point of deployment of the restraint, and the reflected IR energy is detected by a photo-sensitive receiver and analyzed to determine whether an occupant is out of position for deployment of the restraint. In the preferred embodiment, the intensity of the received beam energy and the position of the respective beam are used to construct a table of individual intrusion factors, and a composite intrusion factor based on the individual intrusion factors is categorized by magnitude to form an indication of occupant intrusion level, which in turn, is used to determine whether, or how forcefully, to deploy the restraint in the event of a serious crash.

摘要： A universal, compartment-wide system identifies the presence and position of occupants of a multi-place vehicle by utilizing the occupants to conduct and radiate place-specific radio frequency signals that are received at various locations in the passenger compartment. The place-specific radio frequency signals are developed by low power transmitters disposed in the various seat/place locations, and a receiver disposed at a central location that is remote from the transmitters receives and decodes the signals radiated by the occupants to determine the number and location of the occupants. Additional receivers may be installed in specified regions to detect occupant intrusion into such regions, and in various control panels to assess driver distraction and to tailor the functional content and capability depending on whether a driver or non-driver is interacting with the control panel.
