Abstract: A computer implemented method comprises obtaining a query, obtaining querying source context data, and processing the query to identify an interrogative type corresponding to the query based on language in the query. The method further comprises generating, based on the identified interrogative type, a prompt, the prompt identifying a task for an analytics engine, providing the prompt to the analytics engine, executing, with one or more models, analytics on one or more items of the querying source context data, based on the prompt. The method also includes determining one or more features of an output to be generated based on the identified interrogative type, the output responsive to the query, generating the output based on the executed analytics and the determined one or more features, and controlling a user associated system based on the output.

Abstract: A chain damping and shock absorber system for a chain includes one or more damping devices, each damping device installed to a segment of the chain, such that the chain and the one or more damping devices installed to a chain segment form a damped and compressed chain assembly. In response to a tensile force applied to the chain, the chain segment is extendable to an extended length which is between its compressed length and its full length. Methods of installing the chain damping and shock absorber system are provided.

Abstract: Provided is a process for treating water, wherein the water comprises dissolved ions that comprise an undesired cation, wherein the processes comprises (a) providing a collection of specified polymeric beads wherein 90% or more of the beads by volume are uniform beads; (b) then passing the water through a bed of the collection of polymeric beads to exchange the undesired ion for ions (iv), (c) then passing a regeneration solution comprising dissolved ions (v) of the same species as ions (iv) through the bed of the collection of polymeric beads to exchange ions (v) for the undesired ions.

Abstract: A stair assembly suited for a vehicle entrance includes a plurality of step treads, each of the step treads having a tread width, and a stringer to which the plurality of step treads are secured. The stringer is positioned within the tread width.

Abstract: A lift assist hinge for stowable stairs facilitates deployment and stowing. The lift assist hinge includes a mounting bracket securable to a door frame and including a mounting bracket hinge flange. A threshold plate is securable between the stringers and is pivotable with the stowable stairs. A threshold plate hinge flange connected between the threshold plate and the mounting bracket hinge flange is pivotable relative to the mounting bracket hinge flange. A cam slot is disposed in the threshold plate hinge flange, and a gas spring is connected at one end to the mounting bracket hinge flange and at an opposite end in the cam slot of the threshold plate hinge flange. The opposite end of the gas spring is displaceable in the cam slot.

Abstract: Methods and systems for leak detection in a fluid compression system using a purge system are disclosed herein. In an embodiment, a method for detecting leaks includes determining, during a period of vacuum, a purge exhaust rate of non-condensables from a purge system integrated with a chiller unit. The method includes determining a differential pressure, the differential pressure based on a vacuum side pressure of the chiller unit, where the vacuum side pressure includes at least one of a pressure of a condenser and pressure of an evaporator. The method includes calculating, via a controller, the purge exhaust rate and the differential pressure to identify a leak size based at least in part on the purge exhaust rate.

Abstract: An operating mechanism for a ramp door includes a door actuation system and a limit stop system. The actuation system is connected between the door and a frame or the vehicular structure directly and is operable to pivot the door between closed, deck, and ramp positions. The limit stop system selectively limits the pivoting of the door to a range between the closed and deck portion or to a range between the closed and ramp positions.

Abstract: A ramp door and door frame include a rail kit that deploys automatically when the door is opened and collapses automatically when the door is closed. The door is supported by a cable mechanism when the door is opened. The cable mechanism causes an end rail to pivot up and away from the door when the door is opened and down and toward the door when the door is closed. The end rail cooperates with a door frame to deploy flexible side barriers when the door is opened and to collapse the side barriers when the door is closed.

Abstract: A recreational vehicle (RV) includes a ramp door configurable as a ramp or as a patio deck. A stair is attachable to a side of the door. A railing extends about the perimeter of the door when in the deck configuration. First and second support cables may be connected between the door and the RV to support the door when in the deck configuration.

Abstract: Systems and methods for controlling a cooling circuit for a variable frequency drive (VFD) in an HVACR system are disclosed. The method includes determining, by a controller, an operating condition of a heat sink associated with the VFD. The controller determines whether a temperature of the heat sink is greater than or equal to a heat sink temperature threshold. The method further includes enabling a bypass flow control device in response to the heat sink temperature being greater than or equal to the heat sink temperature threshold.

Abstract: A computer system authenticates a user of a mobile application. In response to authenticating the user, the computer identifies a user profile for the user. The user profile includes a current application state for the mobile application. The computer then selects an application version based on applying a set of rules to the current application state. The computer then sends a response to the mobile device indicating the selected application version, enabling performing an operation for the organization based on the selected version for the application selectively enabling access to services provided by the organization for people.
