Abstract: An airbag cushion is disclosed for use in automotive protective systems. The airbag cushion includes at least one gas deflector which directs gas to a closeable vent to allow gas to be vented out of the cushion when an obstruction is encountered.

Abstract: In modeling material constitutive behavior, a methodology determines tool-chip friction and a position of a stagnation point on a cutting tool. The methodology includes measuring a ratio of cutting force to thrust force and measuring a chip thickness, hch, produced by applying the cutting tool to a material. Initial values are estimated for tool chip friction and position of stagnation. The tool chip friction and position of stagnation are calculated to satisfy a specified relationship. Based on tool chip friction and position of stagnation, material strains, material strain-rates, material temperatures, and material stresses are calculated.

Abstract: Network delay is determined in order to synchronize a clock in a mobile station with a reference clock. Tone are generated that represent a sequence of bits in a synchronization flag. The tones are sampled beginning at a selected sample start time. The sampled tones are demodulated to identify the bit values in the synchronization flag. The demodulator is synchronized with the sampled tones in the synchronization flag by shifting the sample start time until the samples generate an optimum synchronization value. A reference time is then identified according to the optimum sample start time.

Abstract: A motive force detection system prevents an overpowering of the movement of a transport box-carrying slidable tray of a FIMS system past a reference location upon detection of improper mating of the transport box to the FIMS system port plate or an obstruction to the movement of the slidable tray.

Abstract: A wireless alarm system (10) employs two-way transceivers (32, 60) in a network of smoke detectors (16), a base station (12), and other sensors. A keypad (14) is not needed because the system is reset by pressing a Test/Silence button (66) built into every detector or sensor. A siren is also eliminated because a sounder (64) in every detector sounds an alarm when any sensor is triggered. This is possible because every detector includes a transceiver that can receive alarm messages from any other detector. AC power wiring is also eliminated because the base station and sensors are battery powered. Only a telephone connection (48) is needed if the system is to be monitored. In apartments or dormitory installations, smoke detectors in one apartment relay alarm messages to the next apartment, and onto the next, and so on, to a centralized base station for the entire facility.

Abstract: The invention provides for conversion of latitude and longitude to an addressing scheme that supports current TCP/IP (Ipv4) and future addressing (Ipv6/Ipng) requirements. More specifically, it allows a decentralization of the unicast point to a device on the hosted network. Geographical Internet Protocol (geoIP) addressing will facilitate anycast routing schemes where in which the nearest node has a statically assigned geoIP. geo routing, and network management become a function of the geoIP address.

Abstract: A detection system including motion detectors, which are built up and connected in such a manner that movement of an object through successive surveillance areas in one direction will result in the delivery of a first detector signal, which is different from a second detector signal, which will be delivered upon movement of said object through the surveillance areas in at least partially opposite direction. The trend of the detector signals furthermore includes a measure for the distance at which the object passes the detection system. When the structures for the motion detectors are provided on the substrate in a specific manner, it becomes possible to manufacture such motion detectors in a simple manner.

Abstract: A heat sink comprising: a body having an envelope including a flexible portion for thermal contact with a heat source, the envelope being filled with a thermally conductive liquid; and a thermosyphon having one end disposed at least partly within the liquid in the body to absorb heat from the heat source and another end disposed outside the envelope to dissipate heat.

Abstract: An airbag assembly is disclosed. The airbag assembly includes an inflatable cushion having a recess in its lower portion. The recess may form split sections in the lower portion of the cushion. The recess may be configured to receive a rear-facing child car seat during deployment. The airbag assembly may further include a tethering system to control deployment of the split sections of the cushion.
