Abstract: A lift axle can be provided on a truck during or after manufacturing to allow the truck to carry more load. The lift axle can be selectively lifted above the road (e.g., when the truck is empty) and lowered onto the road (e.g., when carrying load requiring an extra axle). There are various challenges in designing a braking system for a lift axle. The embodiments presented herein provide a lift axle brake system that can overcome these challenges. In one embodiment, a lift axle brake system is used that is based on a brake system used to brake a towed vehicle towed by a towing vehicle. Other embodiments are provided.

Abstract: A system and method for managing network communication in an asymmetric network environment. The system includes a gateway. The gateway receives a plurality of packets for transmission over first communication network. The plurality of packets are received via primary network path. The gateway dynamically evaluates the plurality of packets. The gateway classifies the plurality of packets into a latency sensitive packet and a latency agnostic packet. The gateway determines network capacity of the primary network path and a secondary network path. The gateway splits the latency sensitive packet and the latency agnostic packet between the primary network path and the secondary network path. The gateway selects the primary network path for transmitting the latency sensitive packet. The gateway selects the secondary network path for transmitting the latency agnostic packet over downstream transmission.

Abstract: In one embodiment, a system for digitally providing access to one or more articles is disclosed. The system includes one or more locking units to secure the articles in a locked state. A server generates or stores a digital key associated with the article or the locking unit. When the digital key is provided to a portable electronic device of a user, the digital key enables the portable electronic device to alter the locking unit between the locked state and the unlocked state without the user paying for the article or authorizing payment for the article. Upon a first event, the digital key is assigned to the user and provided to the portable electronic device of the user. The first event includes the user initiating a request for access to the article or the digital key, and verification that the user satisfies a predetermined condition.

Abstract: This disclosure provides a memory controller for asymmetric non-volatile memory, such as flash memory, and related host and memory system architectures. The memory controller is configured to automatically generate and transmit redundancy information to a destination, e.g., a host or another memory drive, to provide for cross-drive redundancy. This redundancy information can be error correction (EC) information, which is linearly combined with similar information from other drives to create “superparity.” If EC information is lost for one drive, it can be rebuilt by retrieving the superparity, retrieving or newly generating EC information for uncompromised drives, and linearly combining these values. In one embodiment, multiple error correction schemes are used, including a first intra-drive scheme to permit recovery of up to x structure-based failures, and the just-described redundancy scheme, to provide enhanced security for greater than x structure-based failures.

Abstract: Described herein are concepts, system and techniques which provide a means to construct robust high-field superconducting magnets using simple fabrication techniques and modular components that scale well toward commercialization. The resulting magnet assembly—which utilizes non-insulated, high temperature superconducting tapes (HTS) and provides for optimized coolant pathways—is inherently strong structurally, which enables maximum utilization of the high magnetic fields available with HTS technology. In addition, the concepts described herein provide for control of quench-induced current distributions within the tape stack and surrounding superstructure to safely dissipate quench energy, while at the same time obtaining acceptable magnet charge time. The net result is a structurally and thermally robust, high-field magnet assembly that is passively protected against quench fault conditions.

A downstream end portion of a flow pressurizing section is engaged with an upstream end portion of a rotational flow amplification section. A downstream end portion of the rotational flow amplification section is engaged with an upstream end portion of a flow outlet section. The rotational assembly housing has an interior space extending along a centerline axis of the rotational assembly housing. The rotational assembly is disposed within the interior space of the rotational assembly housing. The rotational assembly and the rotational assembly are jointly configured for causing the rotational axis to extend colinearly with the centerline longitudinal axis of the rotational assembly housing.

Abstract: A power line communication (PLC) self-test for tractor-trailers is provided. The self-test can be performed in a brake controller comprising a PLC transmitter configured to couple with a power line providing power from a tractor to at least one trailer coupled with the tractor. In the self-test, the brake controller causes the PLC transmitter to send a PLC test message on the power line and determines whether the brake controller received the PLC test message from a PLC receiver. If the brake controller did not receive the PLC test message from the PLC receiver, a fault message is generated. The PLC receiver can be in the brake controller or in a PLC receive electronic control unit (ECU), for example. Other embodiments are provided.

Abstract: A water filtration system is shown which uses a number of rigid tubular screen type filter elements having porous exterior and interior sidewalls. The interior sidewalls form an initially open interior axial bore. The filter elements are closed at a bottom end thereof and open at a top end thereof. An elongated spray bar is rotatably mounted for rapid rotation within the open interior axial bore of each of the tubular filter elements. The spray bar has a plurality of slots cut along the length thereof in a predetermined pattern and an internal bore which is in communication with a source of high-pressure air and high-pressure water. The application of high-pressure air or water provides a brief pressure pulse directed radially outward which causes the spray bar to rotate and spray air or water outwardly from the spay bar slots and through the interior sidewall of the porous filter elements to dislodge any collected filter cake from the exterior wall surfaces in use.
