Abstract: An optical filter, a sensor device including the optical filter, and a method of fabricating the optical filter are provided. The optical filter includes one or more dielectric layers and one or more metal layers stacked in alternation. The metal layers are intrinsically protected by the dielectric layers. In particular, the metal layers have tapered edges that are protectively covered by one or more of the dielectric layers.

Abstract: A method for registering an HVAC device in a distributed building management system (BMS). The method includes requesting a token. The token is configured to authorize a registration of the HVAC device. The method further includes receiving the token at a registration service, and receiving a unique ID associated with the HVAC device at the registration service. The method also includes registering the device into a document database of the registration service and generating a device shadow associated with the HVAC device. The method also includes storing the device shadow in the distributed BMS.

Abstract: A dual-use electromagnetic beam system may be used as a remote power delivery system when not needed as an offensive weapon. For example, a system for disabling or destroying uncooperative or enemy assets such as UAVs or ground vehicles may be used during “down time” to provide power to assets that are separated from prime power sources by distance or by logistics.

Abstract: The invention is generally a thumb pick apparatus for playing a stringed musical instrument having an elastic and generally cylindrically shaped cot having an opening and a tip, and having a substantially uniform thickness, with a side “pick pocket” attached thereto proximate to the cylindrical side of the cot, capable of encapsulating and “hugging” the user's plectrum of choice while allowing said plectrum to extend beyond the side of the cot at an approximate right angle such that the plectrum is capable of plucking a string of a musical instrument when the cot is being worn on a thumb digit of a user with the pick pocket holding the plectrum firmly in place.

Abstract: Improved fluid supply grooves in the face of an axial thrust bearing for a crankshaft are disclosed. The grooves have a larger cross-sectional area at the outer radius of the bearing body than at the inner radius of the bearing body.

Abstract: An engine compression braking system having a rocker lever and reset valve assembly to operate an engine in both normal power and braking modes while effectively controlling opening and closing of the exhaust valve for compression braking. The reset valve assembly includes a reset pin mounted in a passage of the rocker arm and movement of the reset pin in the compression mode of braking is controlled by contact of the reset pin with a support shaft which the rocker arm rotates around.

Abstract: A chute for use in pouring concrete into a wall form includes a floor with front, rear and side edges; sides connected to the floor along each of the side edges and projecting upward from the floor; a first flange connected to the floor along the front edge and projecting downward therefrom; and a second flange connected to the floor and projecting downward therefrom. The flanges are substantially parallel and spaced apart by a distance greater than a thickness of a wall form panel; accordingly, placing the chute on top of the wall form panel with the flanges respectively interior and exterior to the wall form securely aligns the chute with the wall form panel. The flanges project downward at approximately a 45° angle. Concrete deposited into the chute is funneled toward the front, and flows off the front edge into the wall form.

Abstract: Variable swirl for internal combustion engines. In one aspect, an apparatus includes a first intake valve controlling air flow from a first intake port to a piston cylinder of the internal combustion engine, where the first intake valve has a first lift profile. A second intake valve controls air flow from a second intake port to the piston cylinder, where the second intake valve has a second lift profile different than the first lift profile. The combination of first and second lift profiles causes a variable swirl of air in the cylinder as a function of engine speed.

Abstract: Paper pulp is added to a stain solution. The stain solution and pulp fibers are mixed to form a slurry. Samples are removed from the slurry and are admixed with dilution water and a bleach. Then, the fibers are moved into a flow cell where they are subjected to a light source adapted to stimulate fluorescence from the stained pulp fiber. Before the fiber slurry enters the flow cell it is mixed with a dilution water of bleach to reduce background fluorescence. The fluorescent light is collimated and directed through a dichroic filter onto a fluorescence splitting dichroic filter.

Abstract: An apparatus and method for controlling exhaust gas recirculation flow. The apparatus and method uses a pressure-bleeding device, such as a wastegate valve, to change the pressure in an internal combustion engine in order to alter the flow rate of the exhaust gas through an exhaust gas recirculation conduit. In one form, the invention includes an inlet conduit connected to an intake manifold of an internal combustion engine and an exhaust conduit connected to exhaust manifold of an internal combustion engine. The pressure-bleeding device is operatively coupled to the intake conduit. Altering the pressure in the intake conduit changes the pressure across the entire system. This change in pressure in the entire system results in a change in pressure across the exhaust gas recirculation conduit. Therefore, a flow is created through the exhaust gas recirculation conduit and can be controlled using the intake side pressure bleeding device.

Abstract: A disc filter sector having an improved attachment system includes a sector base and a sector neck. The sector base includes stiffening members that extend through the sector base and include an attachment end, such as a threaded fastener or region, at the neck mating end of the sector base. The sector neck includes a hold down member proximate the base mating end of the sector neck. To attach the sector base to the sector neck, a mating attachment member, such as a bolt extends through the hold down member of the sector neck and engages with the attachment end of the stiffening members. In one embodiment, the stiffening members, attachment end, and mating attachment members are disposed outside of the flow regions in the sector base and sector neck.
