Abstract: Novel tools and techniques are provided for implementing network experience shifting, and, in particular embodiments, using either a roaming or portable hypervisor associated with a user or a local hypervisor unassociated with the user. In some embodiments, a network node in a first network might receive, via a first network access device in a second network, a request from a user device to establish roaming network access, and might authenticate a user associated with the user device, the user being unassociated with the first network access device. Based on a determination that the user is authorized to access data, content, profiles, and/or software applications that are accessible via a second network access device, the network node might establish a secure private connection through a hypervisor or container communicatively coupled to the first network access device to provide the user with access to her data, content, profiles, and/or software applications.

Abstract: Various examples are provided for cryogenic power extraction. In one example, among others, a system for cryogenic power extraction includes a heat exchanger that can heat a cryogenic working fluid using exhaust heat from a heat source, and a turbine that can generate power from the heated cryogenic working fluid. In another example, a method includes heating a cryogenic working fluid with waste heat from a heat source and driving a turbine with the heated cryogenic working fluid. Power produced by the turbine can be used drive a mechanical load and/or generate electricity for use by an electrical load. For example, waste heat from a combustion engine of a vehicle can be used to generate power for driving mechanical loads of the engine and/or to generate electricity for charging a battery of the vehicle.

Abstract: A pressure relief valve includes a housing having a fluid inlet and at least one fluid outlet. A first structure mounted in the housing and fixed in relation thereto is in magnetic attraction with a second structure coupled to a piston disposed in a portion of the housing. The piston defines a chamber disposed adjacent to the fluid outlet(s) throughout the piston's stroke. The piston includes a sealing element providing a sealing force to prevent flow through the valve. The sealing force is independent of the magnetic attraction force between the first and second structures.

Abstract: A vehicle weight classification system determines the weight of a seat occupant for controlling airbag deployment. Strain gauge sensors preferably provide signals having a magnitude that is indicative of the weight of the seat occupant. A converting module converts the sensor signals into timing information. A microprocessor, which includes a timer module, receives the timing information and makes a weight determination from the timing information.

Abstract: A vehicle weight classification system recognizes the various factors that influence system performance. Some of the factors are compensated for using analog signal processing circuitry or techniques. Other factors are compensated for using digital signal processing techniques. The unique combination of analog and digital approaches, rather than pure analog or pure digital, provides an effective solution at addressing the various factors that influence signals and system performance in a vehicle weight classification system while keeping the cost and complexity of the system within acceptable limits.

The system includes a controller that accommodates the inductants by introducing an appropriate delay in the firing circuit signal to operate the air bag.

Abstract: A vehicle occupant sensing system includes a laser array that generates three beams. A first beam is directed toward an upper body zone, a second beam is directed toward a middle body zone, and a third beam is directed toward a lower body zone. A first sensor assembly receives reflection beams from the upper body zone and generates a first signal that represents a proportional amount of an occupant present in the upper body zone. A second sensor assembly receives reflection beams from the middle body zone and generates a second signal that represents a proportional amount of the occupant present in the middle body zone. A third sensor assembly receives reflection beams from the lower body zone and generates a third signal that represents a proportional amount of the occupant present in the lower body zone. The laser array and the first, second, and third sensor assemblies are all mounted within a common housing that is mounted to a vehicle structure such as an A-pillar or rear view mirror.

Abstract: A switched capacitor circuit for delivering electrical triggering energy to an airbag squib of a supplemental restraint system for a vehicle, or a plurality of such airbag squibs, employs a switching arrangement on both sides of the airbag squib. An energy storage element, which may be a capacitor having stored therein a quantum of energy sufficient to fire the airbag squibs is coupled thereto by a substantially series pair of electronic switches connecting each terminal of the storage capacitor to each terminal of the airbag squib arrangement. A further capacitor is coupled across the airbag squib arrangement, electrically intermediate of the substantially series pairs of electronic switches. A still further capacitor is coupled across the airbag squib arrangement itself. This arrangement can withstand plural short-circuit false conditions, including short-circuits to ground or to supply potential at the terminals of the airbag squib arrangement itself.

Abstract: A control arrangement for a deployable airbag of a vehicle is provided with first and second airbag controllers for receiving a fault signal at the first airbag controller, and for producing at the second airbag controller a deployment command signal that indicates that the deployable airbag is to be deployed. The second airbag controller receives the deployment command signal, and is provided with a communication controller for receiving the deployment command signal, a squib for firing in response to the deployment command signal whereby the deployable airbag is deployed, and an energy transfer arrangement coupled to the communication controller and the squib for transferring a deployment energy to the squib in response to the deployment command signal. The squib is configured to require a predeterminable minimum quantum of energy to effect the firing thereof in response to the deployment command signal.

Abstract: A control arrangement for a deployable airbag of a vehicle is provided with a squib for firing in response to a deployment command signal whereby the deployable airbag is deployed. Bilateral communication is effected between the control arrangement and an airbag electronic controller. Electrical energy and data, including the deployment command signal are conveyed to the control arrangement, and at least self-diagnosis information is conveyed to the airbag electronic controller. The squib is configured to require a predeterminable minimum quantum of energy to effect the firing thereof in response to the deployment command signal. A heater provides a radiated preheat to the squib, whereby the predeterminable minimum quantum of energy applied to effect firing of the squib is exceeded by a combination of the first electrical energy and the radiated preheat energy. The squib and the preheater preferably are both formed on a silicon substrate using a conventional integration process.

Abstract: Two discrete self-heating elements are provided in a silicon based sensor structure. The first, "transfer" self-heating element receives constant current and elevates the temperature of the sensor structure to a desired initial temperature above ambient. The second, "sensor" self-heating element is thermally coupled to the first element and receives a current adjusted based on the difference between ambient temperature and the sensor structure temperature so as to maintain a constant temperature difference. Most of the current flowing through the sensor heating element is thus attributable to fluid flow, and this current can therefore be conveniently used to determine fluid flow parameters (e.g., mass air flow). The elements may comprise thin films which may be interlaced or stacked vertically.

Abstract: A matrix consisting of glass microspheres and cured epoxy is disposed in a cavity at the backside of the silicon diaphragm to strengthen the diaphragm without any significant adverse influence on the ability of the sensor to quickly and accurately respond to changes in mass air flow. The strenthening which is imparted to the device enables it to comply with certain specifications defining the extent to which the device must be capable of withstanding damage from air-entrained dust particles acting on the frontside of the diaphragm.

Abstract: A mass airflow sensor is disclosed which uses a small, thin dielectric diaphragm providing good thermal isolation for thin-film heating and temperature sensing elements, resulting in high flow sensitivity and low current operation of the heating element. The dielectric diaphragm is bounded by a p-etch-stopped silicon rim. The mass airflow sensor includes a primary sensor circuit which maintains a heated primary temperature sensing element and an ambient air temperature sensing element at a constant temperature difference. A slave sensor circuit, which includes a plurality temperature sensing elements, monitors heat loss due to airflow at a particular location on the diaphragm and generates an output signal indicative of airflow which is independent of ambient air temperature.

Abstract: An improved method of making an airfoil includes stacking plies in two groups. A separator ply is positioned between the two groups of plies. The groups of plies and the separator ply are interconnected to form an airfoil blank. The airfoil blank is shaped, by forging or other methods, to have a desired configuration. The material of the separator ply is then dissolved or otherwise removed from between the two sections of the airfoil blank to provide access to the interior of the airfoil blank. Material is removed from inner sides of the two separated sections to form core receiving cavities. After cores have been placed in the cavities, the two sections of the airfoil blank are interconnected and the shaping of the airfoil is completed. The cores are subsequently removed from the completed airfoil.
