Abstract: A multilayer coating for a metallic surface of a component is provided. The multilayer coating includes a first coating having a metal nitride. The first coating at least partially overlaps the metallic surface. The multilayer coating also includes a second coating having a metal. The second coating at least partially overlaps the first coating. The multilayer coating further includes a third coating having a Diamond Like Carbon (DLC) material. The third coating at least partially overlaps the second coating. The first coating, the second coating, and the third coating differ from one another with respect to at least one of hardness, elasticity, corrosion resistance, and lubricity. The multilayer coating includes at least ten overlapping layers having successive layers of the first coating, the second coating, and the third coating in repeating sequence.

Abstract: An undercarriage track joint assembly includes a first link having a first bore at a first end and a second bore at a second, opposite end, and a second link having a first bore at a first end and a second bore at a second, opposite end. A pin may extend between the first and second links, positioned at least partially within the first bores of the first and second links, or partially within the second bores of the first and second links. A bushing may extend between the first and second links, a central axial bore being defined through the bushing. The pin may extend through the central axial bore through the bushing, the pin being coated with a diamond-like carbon (DLC) coating over at least a portion of an outer diameter surface of the pin, the coating providing a contact layer between the outer diameter surface of the pin and an inner diameter surface of the central axial bore through the bushing.

Abstract: A stabilized platform is provided with active sense and adaptive control is provided that allows an operator, during operation, to switch between an electrically assisted operational mode to a manual operational mode. Related systems, apparatus, methods, and articles are also described.

Abstract: An air-cooled internal combustion engine includes an engine block, a blower assembly including a blower housing and a fan, and a static cover. The static cover includes multiple air intake openings and is configured to prevent user access to a moving component of the engine. The blower housing is configured to at least partially direct air to the engine block. The fan is configured to move air into the blower assembly through the air intake openings when rotating in a first direction in a cooling mode and to move air out of the blower assembly through the air intake openings when rotating in an opposite second direction in a debris-removal mode.

Abstract: A rotating screen, for use with a centrifugal fan of an engine, includes a hub having a rotational axis and a plurality of blades extending radially outwardly from the hub. Each of the blades includes a root adjacent the hub, a tip, a leading edge extending between the root and the tip, and a trailing edge extending between the root and the tip. The blades also include an airfoil shape. The rotating screen also includes a band concentric with the hub and interconnecting the tips of the respective blades.

Abstract: An aimed or aiming firearm can be detected before it is able to shoot. Wideband radar signals can be used to identify the barrel of a firearm when the radar antenna and barrel are aiming at or near each other. Signal processing correlates reflected signals to the characteristics of specific firearms of interest, and alerts the user when someone is pointing such a firearm at them. Modern wideband radar systems with fast signal processing speed can enable real-time detection of firearm threats in crowded and cluttered areas before they shoot, which has never before been possible. Related systems, apparatus, methods, and articles are also described.

Abstract: A powered coupling system is configured to interconnect utility lines such as fluid and/or electric lines of a vehicle tractor to a trailer. A curved track is mounted to a frame of the tractor, and the system includes pneumatic and/or electrical connectors that move along the curved track to align the connectors with a corresponding connectors on a trailer. A linear actuator causes the connectors on the tractor to shift vertically to connect and disconnect the connectors on the tractor to connectors on the trailer. The curved track permits alignment of the connectors on the tractor with the connectors on the trailer even if the trailer is not in a straight line with the tractor.

Abstract: Disclosed herein are stabilized weapon mount systems that allow a gunner (i.e. operator of a weapon) to mount and operate a standard weapon in a manner similar to a stand-alone weapon while compensating for the motion of the platform. The system includes an aiming gimbal that is movable by an operator during stabilization into an aiming orientation directed toward a target and a stabilization gimbal nested within the aiming gimbal and adapted to securely couple to a weapon. The stabilization gimbal and aiming gimbal are mechanically coupled by a control unit such that the stabilization gimbal is moved by the control unit and the aiming gimbal is not moved by the control unit. A stabilization device automatically commands the control unit to move the stabilization gimbal relative to the aiming gimbal using the motors to correct for the base movement and maintain the aiming orientation directed toward the target.

Abstract: A method for monitoring a system includes receiving a first data asset from the system, receiving a configuration file, determining whether the configuration file includes the first data asset and an associated first rule engine logic identifier, and running a first rule engine associated with the first rule engine logic identifier responsive to determining that the configuration file includes the first data asset and the associated first rule engine logic identifier. The method also includes sending the first data asset to the first rule engine, receiving a first result from the first rule engine, and sending the first result to a display for presentation to a user.

Abstract: An apparatus and method utilize a fan to direct air through a screen to cool an engine. A cyclonic air cleaner assembly receives air from the blower fan and directs the air towards an air-fuel mixing device of the engine.

Abstract: Stable and active arabinitol dehydrogenases (LAD) from Neurospora crassa and mutants thereof are disclosed. Arabinitol dehydrogenases are useful in the production of xylitol and ethanol from an arabinose containing substrate. Recombinant and heterologously expressed arabinitol dehydrogenases are useful in converting biomass into biofuels and other industrial food products.
