Abstract: Techniques are described herein that are capable of enabling a mounting system to receive threaded and threadless posts. The mounting system may have a cavity (a.k.a. void) that is configured to receive such posts. An interior surface of the cavity may include threads to allow corresponding threads of a threaded post to be twisted (e.g., screwed) into the threads of the cavity. The threads of the cavity may be configured to allow a threadless post to pass through the cavity without being encumbered by the threads. The mounting system uses magnetism and a taper of the cavity to facilitate magnetically and frictionally engaging the threadless post in the cavity.

Abstract: Fan assemblies included within a computing device are described herein. The computing device includes a housing, a heat generating component supported within the housing, and a fan assembly. The fan assembly is operable to move heat generated by the heat generating component out of the housing. The fan assembly is supported within the housing. The fan assembly includes a shaft and a plurality of discs positioned along and fixed to the shaft. The shaft and the plurality of discs are rotatable relative to the housing about an axis of rotation.

Abstract: A method including converting a predetermined number of catalytic zones into a number of finite elements, where the number of finite elements include a number of collocation points represented by a number of mathematical roots in an algebraic system, modeling a catalyst volume including a length of a continuous reactor to have the predetermined number of catalytic zones, representing the first ordinary differential equation, second ordinary differential equation, and third ordinary differential equations in the algebraic system, and performing orthogonal collocation on the number of finite elements in the algebraic system while simultaneously varying at least one of the first number of polynomials and simultaneously varying a percentage of active catalyst and a length of each of the predetermined number of catalytic zones in the second number of polynomials to obtain the mass flow rate of the product for the given chemical reactions.

Abstract: A relay is designed to be used in a circuit where the voltage levels are high in comparison to the spacing between the contacts when open. Contact closure arcing is suppressed by actuating a MOSFET that shorts the contacts together while they open. The same MOSFET can momentarily short the contacts together just before they first begin to close, allowing a test current to be passed through the MOSFET and through the terminals connecting to both relay contacts, to insure that arc suppression will be successful; and if this test fails, then the relay can be disabled by a switch in series with the relay coil to prevent arcing and a possible fire hazard. Relay deactuation can be sensed to trigger arc suppression, and relay actuation can be sensed to initiate fail-safe testing by a circuit that responds no matter which way the relay coil is connected into the external circuit that drives it.

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: An occupant sensing and crash behavior system for a motor vehicle determines the presence and location of an occupant to then control the deployment of supplemental restraint systems such as air bags or inflatable seat/shoulder belts. Crash anticipation and crash severity sensors provide additional inputs to the system to determine the behavior of the crash and the occupants therein. An infrared sensor emits a plurality of beams to determine the location and position of the occupant as does a proximity sensor located on the air bag door or the occupant seat. Occupant weight plus the presence and orientation of a child seat are considered. Seat belt control is provided to control the length of the seat belt during an impact or crash.

Abstract: A solvent extraction process for separating polar hydrocarbons from non-polar hydrocarbons. The solvent-rich extract phase is introduced into a stripping column through two separated loci; the bottoms from the stripping column, a polar hydrocarbon-containing, solvent-rich stream, is introduced into an upper portion of the solvent recovery column. Polar hydrocarbons in concentrated form are recovered as an overhead stream, a lean solvent stream, virtually free from hydrocarbons, is withdrawn as a bottoms product and recycled in part to the extraction zone, and admixed in part with that portion of the extract phase introduced into the upper of the two separated loci. An internally prepared vaporous stripping medium is introduced into the lower portion of the solvent recovery column.

Abstract: Detergent-grade alkylate is produced by the HF-acid catalyzed reaction of aromatic hydrocarbons and an olefinic hydrocarbon. The process utilizes a unique fractionation facility for the recovery and use of an aromatic concentrate, and ultimate recovery of the detergent alkylate product. Integrated within the process is a combination stripping/fractionation column having a contact-condenser disposed therein.
