Abstract: A vehicle occupant protection apparatus (10) includes a sensor (86) for sensing a vehicle crash. An inflatable vehicle occupant protection device (12) has a deflated condition and an inflated condition for helping to protect the vehicle occupant. An inflation fluid source (38) is actuatable to provide inflation fluid to inflate the inflatable device (12).

Abstract: An apparatus (10) for helping to protect an occupant of a vehicle (12) that has a side structure (16) and a roof (28) comprises an inflatable vehicle occupant protection device (14) that is inflatable away from the roof into a position between the side structure of the vehicle and a vehicle occupant. The device (14) has a perimeter (50) defined by an upper edge (52) positioned adjacent the roof (28), an opposite lower edge (54), and front and rear edges (56 and 58) spaced apart along the upper and lower edges. The device (14) includes overlying panels secured together along the perimeter (50) to define an inflatable volume (34) and is free from association with an inflatable tube. An inflator (24) provides inflation fluid for inflating the device (14). A flexible elongated member (90) extends through the device (14) and is coiled around a portion (70) of the inflatable volume (34) of the device. The member (90) has a first end (92) and an opposite second end (94) fixed to the vehicle side structure (16). The member (90) resists movement of the device (14) away from the vehicle side structure (16) when the device is inflated.

Abstract: An intrusion detection system that differentiates between a vehicle intrusion event and a non-intrusion event includes transmitter (16) for transmitting a continuous wave signal that is reflected of surfaces within the vehicle's interior and/or a moving object (i.e., an intruder). The associated reflected signals subsequently return to a receiver (18). An ECU (26) demodulates the return signal into frequency and amplitude components. The ECU (26) further determines a waveform envelope of the demodulated return signals and monitors the envelope waveform during time windows to determine whether their corresponding envelope waveform is indicative of an intrusion event or an non-intrusion event. When an intrusion event is detected, the ECU (26) outputs a control signal to actuate an alarm (34).

Abstract: A system (10) for a vehicle (12) that has a plurality of inflatable tires (14-20), wherein the system has a plurality of sensor units (22-28) associated with the plurality of tires. Each of the sensor units (e.g., 22) senses inflation pressure of the associated tire (e.g., 14) and transmits a signal (e.g., 30) indicative of the sensed tire inflation pressure. A portable unit (44) of the system (10) is located remote from the vehicle (12) and is operable by a person (66) to transmit a signal (48) that conveys a remote control function request. The portable unit (44) also receives a signal (46) indicative of sensed tire inflation pressure and provides an indication of tire inflation pressure to the person (66). A control/communication unit (40) is located at the vehicle and receives the signal (48) conveying the remote function request and causes performance of the remotely requested function. The control/communication unit (40) also receives the signals (e.g., 30) transmitted from the sensor units (e.g., 22) and transmits the signal (46) indicative of sensed tire inflation pressure to the portable unit (44).

Abstract: A vehicle rollover event detector (10) includes a rollover sensor (14). A first accelerometer (80) senses vehicle acceleration in a direction offset from the front-to-rear axis of the vehicle (12) up to a maximum acceleration sensing level and provides a first acceleration signal indicative thereof. A second accelerometer (96) senses vehicle acceleration in the offset direction at acceleration levels in excess of the maximum acceleration sensing level of the first accelerometer and provides a second acceleration signal indicative thereof. A controller (26) selects the first accelerometer or second accelerometer and provides an actuation signal (110) when the signal from the rollover sensor and the selected first or second accelerometers both indicate a vehicle rollover event.
