摘要:
An airbag can include a base panel and a cushioning panel that cooperate to define an inflatable chamber. A deflector can be positioned between the base panel and the cushioning panel. The deflector can be attached to the base panel so as to define a lower inflation aperture that directs inflation gas toward a bottom end of the base panel. In some arrangements, the airbag can include a tether that extends through the lower inflation aperture.

A duplex firing initiator for an airbag inflator includes both a primary initiator and a secondary initiator for electrical connection to a Restraint Control Module. In the duplex firing initiator, current is conducted in a forward polarity through the primary initiator to actuate the primary initiator and current is conducted in a reverse polarity through the secondary initiator to actuate at least the secondary initiator.

An airbag assembly may include an inflatable curtain airbag with a stowed configuration and a deployed configuration. The inflatable curtain may have a first protection zone and a second protection zone that inflates forward of the first protection zone to provide enhanced protection. The second protection zone may be folded against the first protection zone so that, during deployment, the second protection zone pivots to unfold relative to the first protection zone. The airbag assembly may have a restraint member that limits the ability of the second protection zone to unfold to a configuration parallel to the first protection zone, thereby keeping the second protection zone at an optimal location to protect the vehicle occupant from rollover and/or small overlap or oblique collisions. The restraint member may be a tether with ends secured proximate the top of the second protection zone and the top of the first protection zone.

Airbag assemblies and active vents for airbag assemblies are disclosed. An airbag assembly can include an airbag cushion that defines an inflatable chamber and an active vent that comprises an aperture and a patch configured to plug the aperture. A first control tether is coupled to the patch and coupled to the airbag cushion. The first control tether is drawn taut as the cushion expands during deployment to draw the patch toward the aperture from a first position that allows unobstructed venting through the aperture to a second position that obstructs venting through the aperture. The first control tether, or a second control tether, is configured to be drawn taut to close the active vent. Responsive to impact with the airbag cushion, a control tether is configured to slacken to open the active vent.

An I/Q mixer and processing method for a radar system include an RF input and an LO input. Phase shifters apply a selectable phase shift to the LO signal to produce a first phase-shifted version of the LO signal and a second phase-shifted version of the LO signal, the first and second phase-shifted versions of the LO signal being in quadrature. A first set of switches is controllable to selectively apply the selectable phase shift to the LO signal. A first mixer unit receives the RF signal at a first input of the first mixer unit, and a second mixer unit receives the RF signal at a first input of the second mixer unit. A second set of switches is controllable to apply one of the first and second phase-shifted versions of the LO signal to one of a second input of the first mixer unit and a second input of the second mixer unit and to apply the other of the first and second phase-shifted versions of the LO signal to the other of the second input of the first mixer unit and the second input of the second mixer unit. A counter generates a count for sequencing through states of the first and second sets of switches.
摘要:
A system is provided for enhancing inertial sensing within a vehicle. The system determines measured rotational rates and translational accelerations of the vehicle using an inertial measurement unit. In addition, the system also determines estimated rotational rates and translational accelerations of the vehicle based on a remote sensing system. The system generates compensated rotational rates and translational accelerations to reduce gain errors or offset errors of the inertial measurement unit based on the estimated rotational rates and translational accelerations.

Methods of forming a curable pre-impregnated composite precursor material with radiation ( e.g. , actinic or electron-beam) curable resin composition systems are provided, as are the curable pre-impregnated composite precursor materials themselves. The resin systems have reversible temperature-viscosity control, which are advantageously used to form curable pre-impregnated composite precursor materials (pre-preg) that can be cured to form a composite article. The uncured resin composition comprises: (a) an acrylate or a methacrylate monomer; (b) an oligomer species selected from the group consisting of: polyethers, polyesters, epoxies, and combinations thereof; and (c) a photoinitiator. The uncured resin has a first viscosity at 21°C (70°F) of ≥ about 200,000 centipoise (cP) and a second viscosity of ≤ about 5,000 cP at 65°C (149°F) or above.
