摘要:
A novel active hood system is disclosed. The active hood system is designed such that in the event of a pedestrian/vehicle accident, the active hood system will soften the impact between the pedestrian and the vehicle by moving the vehicle hood into an elevated position. In some embodiments, the active hood system is constructed such that during a pedestrian/vehicle collision, the active hood system will raise the vehicle hood into an elevated position by having the hood move through a first travel distance and a second travel distance. The active hood system includes an actuator and a hinge. The actuator may be attached to the hinge. The actuator is designed such that if it is deployed, the actuator will raise the hood into the elevated position. Additional embodiments may also be made in which the actuator is vented during deployment. A dampener is also added to the active hood system. The dampener is designed to dampen the movement of the hood as the hood is moved through the second travel distance.
摘要:
A dual stage inflater for providing an extended flow of inflation gas to an airbag or inflatable curtain is disclosed. The inflator includes a first gas chamber having an exit orifice, the exit orifice having an open configuration and a closed configuration. Additionally, the inflator has a second gas chamber in gaseous communication with the first gas chamber. The first and second gas chambers are separated by a flow restrictor positioned between them. This restrictor controls the flow of gas out of the second gas chamber. The inflator includes an initiator in communication with the interior of one of the gas chambers that is configured to selectively initiate a flow of gas through the exit orifice of the first gas chamber. The exit orifice of the inflator may be disposed within an inlet port of an inflatable curtain to cause inflation gases exiting the inflator through the exit orifices to enter directly into the airbag or inflatable curtain.

摘要:
An inflation system and method of operation are provided which utilize or employ the magnetic characteristics of certain gases to selectively alter or change one or more inflation characteristic of the inflation output provided thereby or resulting therefrom. An inflation system for providing a supply of inflation medium to an inflatable restraint element includes an inflator device having a first chamber having contents including a quantity of at least one gaseous material having magnetic characteristics. The inflation system also includes a magnetic field inductor in magnetic field change inducing communication with at least a portion of the first chamber contents quantity of the at least one gaseous material having magnetic characteristics, wherein activation of the magnetic field inductor effects a change in at least one inflation characteristic of the inflator device, e.g., rise rate, gas mass flow rate and pressure output, produced or generated by the inflator.
摘要:
A method of hybridizing a first nucleic acid to a second nucleic acid at least partially complementary to the first nucleic acid by (1) providing a sample vessel and pressure controller for the vessel; and (2) contacting the first and second nucleic acids within the vessel at a pressure above ambient pressure that is effective to enhance hybridization of the first and second nucleic acids.
摘要:
The invention relates to (1) pressure-mediated dissociation of an analyte complexed with an endogenous binding partner to enable detection of a complex formed from the analyte and an exogenous binding factor, (2) pressure-mediated association of an analyte and an exogenous binding partner to enable more rapid and/or more sensitive detection of an analyte, and (3) pressure-mediated association and dissociation of biomolecular complexes to enable separation of one biomolecule from a complex mixture. Pressure can be used to improve assays by dissociating endogenous analyte complexes and improving assay speed and sensitivity by associating the analyte molecules with exogenously supplied binding partners. Pressure can also be used to improve the separation of compounds from contaminated mixtures. Methods of assaying an analyte in a sample having an endogenous complex between the analyte and an endogenous sample component include dissociating the analyte from the endogenous component using pressure and reacting the analyte with an exogenously supplied specific binding reagent to determine complexation between the analyte and the binding reagent.

An inflator apparatus for inflating an inflatable device and a method are provided which utilize a burst disk arrangement which results in a sequential opening regime such as may desirably provide a form of the above-described S curve inflation performance behavior without necessitating the use of or reliance on mechanical opening devices such as projectiles or piston members.
摘要:
Inflatable device inflation assemblies wherein a gas source material is released from an inflator apparatus into an inflatable device wherein the gas source material may, such as upon actuation of an initiator device situated within the inflatable device, dissociate or otherwise form gaseous products for the inflation of the inflatable device. An inflatable restraint system is also provided which includes a plurality of inflatable devices each operatively joined with a chamber which contains a dissociative gas source material. The system includes at least one first initiator effective upon actuation to initiate dissociation of the gas source material within a selected one of the plurality of inflatable devices. A method for inflating an inflatable device is also provided wherein a quantity of at least one gas source material is released into the inflatable device and which gas source material, when initiated, undergoes dissociation to form dissociation products including at least one gaseous dissociation product.
