Abstract: A gearcase seal assembly includes an inboard seal body and an outboard seal body both extending about and along a center axis between respective interior and exterior portions. The inboard and outboard seal bodies include respective inboard and outboard pockets configured to receive first and second surfaces of a gearcase of an axle assembly, respectively. The interior portions of the inboard and outboard seal bodies include respective gutters configured to direct fluid away from the first and second surfaces of the gearcase, respectively. The exterior portion of the inboard seal body includes plural fingers disposed outside of the inboard pocket and extending in one or more directions away from the inboard pocket. The exterior portion of the outboard seal body includes plural other fingers disposed outside of the outboard pocket and extending in one or more directions away from the outboard pocket.

Abstract: This disclosure describes techniques for determining whether a transaction may be finalized with a user that exits a facility. To do so, the inventory management system may first determine whether the inventory management is to resolve any events prior to finalizing the transaction. In some instances, the inventory management system may refrain from finalizing a transaction with a user that exits the facility if the user is associated with a low-confidence result/event, if the user remains a candidate user for an unresolved event, or if a global-blocking event is in place at the time of the user's exit. In some instances, meanwhile, the transaction with a user may be finalized upon the user's exit of the facility if the user is associated with high-confidence events/results, is not associated with any low-confidence events/results, is not a candidate user for an unresolved event, and if no global-blocking event is in place at the time of exit.

Abstract: A seal structure can include a protruding portion of an outer surface of a body. An inner surface of the protruding portion may define at least a portion of a channel. The protruding portion may be configured to engage and at least partially deform into the channel in response to a load generated by pressing an outer surface of the protruding portion against a contact surface of a contact member to provide a seal between the body and the contact member. The seal structure may be integrally formed within the body as a monolithic object. The body may face towards the contact surface of the contact member during operation of the seal structure. A method may include forming a monolithic body with an integral seal structure by additively fusing material so that the body has an outer surface facing towards a contact surface of a contact member.

Abstract: Various methods and systems are provided for an exhaust gas recirculation system. In one example, an exhaust gas recirculation cooler includes an exhaust gas inlet and an exhaust gas outlet spaced from the exhaust gas inlet; a plurality of cooling tubes disposed between the exhaust gas inlet and exhaust gas outlet; and a baffle positioned proximate to the exhaust gas inlet and interposed between the plurality of cooling tubes and the exhaust gas inlet, where the baffle directs exhaust gas entering the EGR cooler through the exhaust gas inlet to the plurality of cooling tubes in a defined path.

Abstract: A resistor grid system includes a resistor strip including multiple pins. The resistor grid system also includes an insulation board coupled to the resistor strip through the multiple pins and configured to provide a structural support. The insulation board is made of a composite material. The composite material includes a nitrogen-containing aromatic thermosetting polymeric resin and a filler.

Abstract: A double walled reinforcement structure and method for making a double walled reinforcement structure having a plurality of longitudinally extending and nested structural members. Each structural member comprises a first cell having a first cross-section and a second cell having a second cross-section. The second cell is positioned within the first cell and the second cell contacts the first cell in a plurality of locations to provide mutual support of the cells in a manner increasing the tensile and compressive strength of the structure.

Abstract: A test fixture, test apparatus, and test method utilize a radially cut tire section that is mounted and sealed to a test jig in a airtight manner such that an air chamber is formed between an innerliner surface of the radial tire section and a recessed portion of the jig body such that the tire section may be pressurized on the test jig. A test surface is provided and either the test surface or the test jig is moveable relative to the other to the other to provide a dynamic load to the radial tire sections.
