Abstract: A compressor includes a housing defining a sump for collecting lubricant, a pump for circulating the lubricant within the housing, the pump comprising a lubricant intake tube defining a pump inlet positioned within the sump, and a noise dissipation media positioned within the sump on a surface of the lubricant and above the pump inlet, wherein a media void is defined around the lubricant intake tube.

Abstract: Operating a gaseous fuel engine includes spark-igniting gaseous hydrogen fuel and air, and propagating combustion gases of the spark-ignited mixture outwardly from a spark gap. The propagating combustion gases are impinged upon a cone surface of a piston so as to limit a flame area of the propagating combustion gases. Additional gaseous hydrogen fuel and air is ignited in the combustion cylinder by way of the propagating combustion gases to urge a piston toward a bottom-dead-center position.

Abstract: An office-type chair includes a back support having a support frame, front and rear shells, a cushion and a cover. The perimeter edge of the cover wraps around the side of the cushion and the front shell and is inserted between the front and rear shells to form a finished edge for the cover. The front shell may include a central flex section, and a lumbar pad may be positioned between the front shell and the rear shell and adjacent to the central flex section. One or more lumbar enhancement ribs on the front shell may augment the pressure distribution of the lumbar pad as it is vertically adjusted.

Abstract: This disclosure provides epimerase enzymes useful for commercial scale production of allulose from fructose. The disclosed enzymes (“epimerase variants”) are variants of Burkholderia multivorans CGD1 xylose isomerase engineered to have improved catalytic activity of about 1.5- to 2-fold compared with the parent enzyme.

Abstract: The disclosure is directed to a continuously and automatically updated authentication mechanism for authentication, in real-time, the processing of transactions at point of sales devices based on corresponding target-specific identifiers. In one aspect, a processing server includes one or more memories having computer-readable instructions stored therein, and one or more processors. The one or more processors are configured to execute the computer-readable instructions to receive a request for processing a transaction; identify a merchant-specific identifier for a merchant associated with the transaction; determine, in real-time and using a machine trained model, whether the merchant-specific identifier is a valid merchant-specific identifier or not; and process the transaction based on whether the machine trained model indicates that the merchant-specific identifier is valid or not.

Abstract: A system for exhaust gas remediation includes an engine, a plasma reactor, and a pulse source. The engine emits exhaust gas that includes NO molecules and NOx molecules. The plasma reactor includes an internal chamber that is fluidly connected to the engine such that the exhaust gas flows into the internal chamber. An electrode is disposed within the internal chamber of the plasma reactor. The electrode is electrically coupled to an electrical pulse source. The electrical pulse source delivers electrical pulse to the electrode to form a plasma from the exhaust gas, which removes at least a portion of the NO molecules and at least a portion of the NOx molecules.

Abstract: This invention relates to methods and systems for reducing the concentration of SOx and/or NOx in gas streams.

Abstract: A system and method for analyzing directory service environment attack paths for an enterprise may continuously collect data about the attack paths and provide alerts. The system and method may also analyze the nested object relationships within Directory Services alongside objects at risk for Credential Theft to calculate all possible attack paths within the environment.

Abstract: Examples described herein include systems, methods, instructions, and other implementations of transactional promotions. One embodiment includes receipt of an authorization request message for a transaction associated with an account number. The authorization request message includes a merchant category code and does not include promotion information. A determination is then made that the transaction is eligible for a promotion based on the merchant category code. The promotion is then automatically applied to the transaction at the account number, and an authorization response message is then generated authorizing the transaction.

Abstract: A method of generating an audience of user equipment users according to a user-searchable index for audience curation. The method includes generating the user-searchable index for audience curation, receiving user input describing a user's desired characteristic of an audience as user-friendly input through a public-facing selection interface, and parsing the user input to generate a distributed search query complying with a search syntax of a search engine. The method further includes searching the user-searchable index to determine a quantity of prospective audience members having the desired characteristic, transmitting the quantity of prospective audience members to the user to cause a terminal of the user to display the quantity of prospective audience members on a display, and transmitting the query to a first network element configured to execute the query to perform a desired action of the user when the user approves the quantity of prospective audience members.

Abstract: A caster wheel assembly includes a frame configured to pivotally couple to a tool bar, a sub-frame rotatably coupled to the frame, and a connecting linkage configured to control movement of the frame relative to the tool bar. The caster wheel assembly also includes a locking assembly, which includes a lock lever movably coupled to the frame, wherein the lock lever includes a locking element and a release element, a locking structure fixedly coupled to the sub-frame, and a driving element fixedly coupled to the connecting linkage. The locking element is configured to block rotation of the sub-frame relative to the frame while the locking element is engaged with the locking structure, and the driving element is configured to contact the release element as the connecting linkage moves the frame downwardly relative to the tool bar to drive the locking element to disengage the locking structure.

Abstract: A posture correction and weight balance apparatus includes a back support, a scale body, and a reflective body. The scale body includes a base, a left platform, a right platform, at least one first display, a left weight sensor, and a right weight sensor. The back support and the reflective body are oppositely positioned of each other about the scale body and terminally and perpendicularly attached to the base. The left platform and the right platform are adjacently aligned across the back support and mounted onto the base. The at least one first display is positioned adjacent to the reflective body and mounted onto the base. The left platform is electronically connected to the at least one first display through the left weight sensor. The right platform is electronically connected to the at least one first display through the right weight sensor.

Abstract: Disclosed herein are three geneses of proteins herein established to exhibit a fructose to allulose epimerase activity that are useful for production of allulose from fructose at high temperatures and at low pH in the range of 4.5 to 6.0. Two of the three geneses descend phylogenetically from a common ancestral protein defined herein, and these geneses are distinguished from each other by different parental descendant proteins also defined herein. The proteins with high levels of sequence identity to the parental nodes defining from these two geneses generally exhibit higher levels of specific fructose to glucose epimerase activity than prior known fructose to allulose epimerases and exhibit such activity at low pH. A third genus is not defined by phylogenetic origin except by not descending from the same ancestor as the first two geneses but generally exhibit similar levels of fructose to allulose epimerase activities as prior art epimerases described to be useful for fructose to allulose conversion.
