摘要： A vehicle occupant restraint system (10) has an actuatable occupant restraint device (16) with an aspect adjustable for adjusting actuation of the restraint device. An associated control method controls the system (10). Within the system (10), a sensor (40) senses a vehicle operating parameter functionally related to crash acceleration and provides a signal (42) indicative thereof. A threshold determination function (44) of a microcomputer (18) determines whether the signal (42) from the sensor (40) exceeds a threshold value. An occupant characteristic sensor (26) senses an occupant characteristic in response to a determination that the signal (42) from the sensor (40) exceeds the threshold value and provides a signal (28A) indicative thereof. A restraint adjustment controller function (38) of the microcomputer (18) determines adjustment of the adjustable aspect of the restraint device (16) in response to the determination that the signal (42) from the sensor (40) exceeds the threshold value and in response to the signal (28A) from the occupant characteristic sensor (26). The adjustment controller function (38) provides a signal (20A) indicative of the determined adjustment to cause adjustment of the restraint device (16).

摘要： An apparatus (20) for sensing pressure in a stiff wall sealed vessel (30) comprises a speaker (60) operatively coupled to the vessel (30) for, when energized, transferring energy to pressurized fluid in the vessel (30). The energy transferred from the speaker (60) establishes oscillations of the pressurized fluid in the vessel (30). A piezoelectric capacitive sensor (62) is operatively coupled to the vessel (30) for providing a received electrical signal having a frequency value indicative of the oscillation frequency of the pressurized fluid in the vessel (30). A receiver circuit (70, 90, 110) is operatively connected to the capacitive sensor (62) and provides a fluid resonating signal having a frequency indicative of the natural frequency of the oscillating pressurized fluid in the vessel (30). The natural frequency of the pressurized fluid is indicative of the fluid pressure in the vessel (30). A drive circuit (120, 164) is operatively connected to the receiver circuit (70, 90, 110) and to the speaker (60). The drive circuit ( 120, 164) initially drives the speaker (60) with a square wave pulse and subsequently drives the speaker (60) with an energy wave having a frequency equal to the natural frequency of the pressurized fluid in the vessel (30) so as to lock onto the natural frequency.

摘要： An occupant sensing apparatus for use in an occupant restraint system comprises a film having an electrical characteristic with changeable states and a contact member. When an occupant sits in a vehicle seat, the contact member pushes on the film and changes the state of the electrical characteristic. An electric circuit is connected to the film for providing a first signal when the film indicates an occupant is not present, a second signal when an occupant is present, and a third signal if the film and the circuit become disconnected. The occupant restraint system is enabled when either an occupant is present or an electrical fault condition occurs. In accordance with another embodiment of the invention, an array of sensors located in the seat determines the occupant's position and weight and controls deployment of the occupant restraint system in response to the determined position and weight.

摘要： A method and apparatus is disclosed for controlling actuation of a passenger restraint system in a vehicle. The apparatus includes an accelerometer for providing a time domain vibratory electric signal having frequency components indicative of a vehicle crash condition. An A/D converter converts the accelerometer signal into a digitized signal. A fast Fourier transform device transforms the digitized time domain vibratory electric signal over at least two time intervals into frequency domain signals. The amplitudes of all the frequency bins over the entire frequency spectrum for each frequency domain signal are summed to provide a value corresponding to the integral of the amplitudes of all the frequency bins over the entire frequency spectrum for the associated frequency domain signal. The integral values of the frequency domain signals are summed. A microcomputer monitors the sum of the integral values of the frequency domain signals and actuates the passenger restraint system when the sum of the integral values of the frequency domain signals is greater than a predetermined threshold thereby indicating a particular type of vehicle crash is occurring.

摘要： An occupant safety protection system (8) capable of sensing the misuse of a safety belt system (10). The invention includes: a shoulder belt portion (13), a field generator means (243) for generating a detection field (202), a disturbance tag means (250) attached to the shoulder belt portion (13) and a tag detection circuit means (19) which determines seat belt misuse and sends an output indicative thereof. When the seat belt system is being properly used the disturbance tag (250) does not disturb the detection field. Conversely, when the seat belt system is being improperly used the disturbance tag disturbs the detection field. The tag detection circuit sends an output indication (245) corresponding to the state of the seat belt system use.
