  • Patent number: 9481335
    Abstract: An apparatus (50) detects a pedestrian/vehicle impact, the apparatus including a plurality of sensors (62, 64, 66) mounted near a forward location of a vehicle (52), each sensor providing an associated signal indicative of an impact event. A metric determining device (80) determines metric values for each of the sensor signals. A controller (80) determines if any of said determined metric values indicates the occurrence of a misuse event. The controller also determines if a pedestrian/vehicle impact event is occurring by comparing the metric value of at least one sensor signal against a selectable threshold. An actuation signal is provided in response to the comparison. The selectable threshold is selected in response to the determined occurrence of a misuse event. An actuatable pedestrian impact mitigation device (84) is attached to the vehicle and is actuated in responsive to the actuation signal from said controller.

  • Publication number: 20080141358
    Abstract: An identification and administration system applied to P2P gateway and a method for the same are proposed. The system is installed in a kernel space, and a plug-in kernel module is in the kernel space to finish preprocessing and application processing of packets on the kernel space without the need of copying data to the user space for processing. Moreover, a connection cache is provided in the kernel space to process source/destination IP addresses, connection ports and protocol identifiers of all packets to recognize and then block identical request packets in reconnections. Therefore, the throughput of content-level security gateway can be increased, and the processing efficiency of packets can also be enhanced.

  • Patent number: 6776435
    Abstract: The present invention is directed to controlling a vehicle multistage actuatable occupant restraining system (14, 18). A crash sensor (32, 36) senses crash acceleration and provides a crash acceleration signal (110, 160) indicative thereof. Crash velocity and crash displacement are determined (118, 168) in response to the crash acceleration signal. A first stage (90, 94) of the multistage actuatable occupant restraining system is actuated when the determined crash velocity as a function of crash displacement exceeds a low threshold (130, 132, 180, 182). A crush zone accelerometer (40, 42) senses crash acceleration at a crush zone location. The crush zone acceleration as a function of the crash displacement is compared (226, 256) against a crush zone threshold (220, 222, 250, 252). The value of the low threshold (130, 180) is switched to a different value (132, 182) when the crush zone acceleration exceeds the crush zone threshold.

A transverse accelerometer (34) senses transverse crash acceleration. The transverse acceleration as a function of the crash displacement is compared (226, 278) against a transverse threshold (268). The value of the low threshold (130, 180) is switched to a different value (132, 182) when the transverse acceleration exceeds the transverse threshold.
