摘要： An apparatus for restraining a vehicle occupant during a crash of the vehicle comprises a first crash sensor securable to the vehicle and having a sensitivity axis parallel with a front-to-rear axis of the vehicle. The first sensor provides a signal having a value functionally related to crash energy directed parallel to the front-to-rear axis of the vehicle and impervious to crash energy directed parallel to a side-to-side axis of the vehicle. A second crash sensor is also securable to the vehicle and has a sensitivity axis parallel with a side-to-side axis of the vehicle. The second crash sensor provides a signal having a value functionally related to crash energy directed parallel to the side-to-side axis of the vehicle and impervious to crash energy directed parallel to the front-to-rear axis of the vehicle. The first and second crash sensors have their sensitivity axes oriented along mutually orthogonal axes. The apparatus further comprises a controller connected to the first and second crash sensors for determining a crash vector of a crash condition in response to the signals from the first and second crash sensors. Each of a plurality of actuatable occupant restraint devices is connected to the controller. The controller controls which of the plurality of actuatable occupant restraint systems is or are actuated in response to the determined crash vector.

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 corresponding frequency bins of the frequency domain signals are summed over the entire frequency spectrum, bin-to-bin. A microcomputer monitors the sum of the amplitudes of at least one selected frequency bin of the frequency domain signals and actuates the passenger restraint system when the sum is greater than a predetermined threshold thereby indicating a particular type of vehicle crash is occurring.

摘要： The present invention is a power supply for a fluorescent light, particularly a sub-miniature fluorescent light (SFL) which provides compensation for temperature and age effects of the fluorescent light. One or more SFLs are powered by a variable output anode controller and a variable output cathode controller, wherein the illumination output of the SFLs is selectively adjustable based upon the voltage output of one or both of the anode and cathode controllers. In a first example of implementation of the invention, an illumination feedback circuit is provided to the anode/cathode controller, wherein the voltage output is adjusted to compensate for diminished illumination, caused for example by cold operating conditions or age of the sensed SFLs. In a second form of the present invention, a temperature feedback circuit is provided to the anode/cathode controller to provide the aforesaid voltage adjustment to compensate for diminished illumination. In another aspect of the present invention, the SFLs are placed into a ready-state for being presently illuminated based upon sensing of a wake-up signal.

摘要： A vehicle seat belt retractor system (10) includes two seats (16, 18) each having its own integrated seat belt webbing retractor (60, 112). Each retractor (60, 112) includes locking assembly (76, 80) for blocking belt withdrawal in response to an electrical signal. At a central location in the vehicle spaced from the seats (16, 18), a sensor (24) is disposed for sensing vehicle deceleration exceeding a predetermined deceleration and for providing a control signal indicative thereof. An RF transmitter (42) is electrically connected with the sensor (24) and is actuatable in response to the control signal to transmit an RF signal. An RF receiver (100, 114) on each vehicle seat (16, 18) receives the RF signal and provides an output signal to actuate the locking assembly (76, 80) of the two seat belt retractors (60, 112). Each vehicle seat (16, 18) also has (a) a battery (98) for supplying electric power to actuate the locking assembly (76, 80) of the retractors (60, 112) and (b) a piezoelectric member (90) responsive to an occupant sitting on the seat for generating an electric current to charge the battery (96). In a second embodiment, a separate deceleration sensor (24a) is mounted on each vehicle seat for electrically actuating its associated retractor. In a third embodiment, the transmitted signal provides the power for actuating a vehicle occupant restraint (178).

摘要： An occupant restraint device (10) for a vehicle includes an air bag (16) mounted in the vehicle door (14) and an accelerometer (30) for measuring sideways acceleration of the door (14). A controller (20) monitors the accelerometer output (34, 36) and determines if the door (14) is in a door opening event or if the vehicle is in a sideways crash condition. The controller (20) actuates the air bag (16) if a vehicle crash condition is detected and disables actuation of the air bag (16) if the vehicle door (14) is determined to be opening.

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.
