Abstract: Systems and methods for dynamic user profile projection are provided. One or more aspects of the systems and methods includes computing, by a prediction component, a predicted number of lookups for a future time period based on a lookup history of a user profile using a lookup prediction model; comparing, by the prediction component, the predicted number of lookups to a lookup threshold; and transmitting, by a projection component, the user profile to an edge server based on the comparison.

Abstract: Systems and methods for dynamic user profile management are provided. One aspect of the systems and methods includes receiving, by a lookup component, a request for a user profile; computing, by a profile component, a time-to-live (TTL) refresh value for the user profile based on a lookup history of the user profile; updating, by the profile component, a TTL value of the user profile based on the request and the TTL refresh value; storing, by the profile component, the user profile and the updated TTL value in the edge database; and removing, by the edge database, the user profile from the edge database based on the updated TTL value.

Abstract: A bidirectional electroosmotic pump may be provided. The bidirectional electroosmotic pump may be made of materials that are biocompatible and non-ferrous. The bidirectional electroosmotic pump may be part of an implantable medical device for the purpose of medicine delivery. The bidirectional electroosmotic pump may contain a working fluid and may facilitate the delivery of a separate payload fluid. In an exemplary embodiment, the bidirectional pump may contain bellows which may allow the pump to deliver the payload fluid through a series of valves and/or catheters. In another embodiment the bidirectional electroosmotic pump may contain a pump sensing mechanism to monitor the state of the pump.

Abstract: A check valve assembly for use with a liquid jet cutting system can include a check valve body a high-pressure fluid inlet on one end and a high-pressure fluid outlet on the other end along a central axis of the check valve body. The check valve body can have a first metallic seal surface on an outer surface of the check valve shaped to engage an endcap of the liquid jet cutting system to form a first seal. The assembly can include an annular low-pressure fluid chamber surrounding a portion of the check valve body and defined at least in part by an annular gasket, the check valve body, the first seal, and the endcap. The check valve body can include a low-pressure fluid channel, and a check valve positioned between the low-pressure fluid channel and a high-pressure fluid chamber.

Abstract: A cage for a fluid valve. The cage includes a first cage ring, a second cage ring, and a lattice structure disposed between the first cage ring and the second cage ring. The lattice structure defines a plurality of interconnected flow paths between an internal surface of the lattice structure and an external surface of the lattice structure. The lattice structure has a non-uniform density.

Abstract: A valve includes a valve body forming a channel defining a fluid flow path extending from an inlet port to an outlet port of the valve body via a gallery disposed therebetween, an opening disposed in communication with the gallery, a valve assembly at least partially disposed through the opening and in the gallery, and a set pin having a central longitudinal axis. A valve disc of the valve assembly moves between a first position spaced from a valve seat of the valve body and a second position in contact with the valve seat. The set pin is coupled to and at least partly supported by the valve assembly to maintain the valve assembly in the first position. The fluid flow path allows a fluid to flow through the valve body in a first direction and a second direction opposite the first direction. The set pin is adapted to disengage a portion of the valve assembly when contacted by a fluid traversing the fluid flow path in the second direction, allowing the valve disc to move to the second position.

Abstract: Monitoring systems and methods for a relief valve system. In one example, a monitoring system for a relief valve includes at least one tilt sensor coupled to one or more of a cover or a latch of the relief valve. The at least one tilt sensor is associated with an interface. Upon detection by the at least one tilt sensor that one of the cover is open or the latch is unlocked, a signal is transmitted by the interface indicating one or more of the cover is open or the latch is unlocked.
