Abstract: A data structure for managing inventory information of a user device from an inventory of user devices is provided. In one example, the data structure includes: a device document containing a general product profile of a device from an inventory and a first device identity profile of the device; an embedded universal integrated circuit card (eUICC) document containing multiple data fields describing an eUICC embedded in the device, wherein the eUICC contains at least one embedded subscriber identification module (eSIM); and an eSIM profile document comprising at least one eSIM profile corresponding to the at least one eSIM contained in the eUICC, wherein the at least one eSIM profile contains multiple attributes describing the eSIM.

Abstract: A system, method, and platform for converting academic research publications into quality-assured, practitioner-accessible content. The invention employs a network of specialized, autonomous AI agents working collaboratively with original authors to transform complex academic papers into industry-relevant, multimedia-enriched articles. The system performs contextual analysis of academic papers, identifies key patterns and structural elements, and correlates these with industry concepts. It dynamically integrates multimedia elements, establishes collaborative feedback loops with original authors, and incorporates simulated peer review mechanisms. The invention features continuous learning capabilities that leverage author interactions to improve future performance.

Abstract: A computer-implemented method for supply chain management is provided. In one example, the method includes: validating a supply chain event involving an inventory item based on a pre-established rule; determining presence or absence of a supply chain issue regarding the inventory item based on the validation; determining an issue type of the supply chain issue based on model issue types from an issue database; validating the supply chain issue based on pre-established issue templates from the issue database; generating one or more solutions to solving the supply chain issue; generating a computer ticket reporting the supply chain issue based on a pre-established ticket template from a ticket database; and transmitting the computer ticket to a support service.

Abstract: A computer-implemented method is provided. In one example, the method includes: managing serialized inventory information regarding user devices according to a serialized inventory live status (SILS) data structure of the user devices, the serialized inventory information including first serialized inventory information regarding a first user device; obtaining a first state of the first user device, wherein the first state indicates whether the first user device is locked or unlocked with respect to a carrier service; determining if the first user device is eligible for unlock according to a set of pre-established rules specifying conditions for the first user device to be eligible for unlock; and transmitting an unlock command to the first user device, wherein the unlock command is executable to effectuate a change of the first user device from being locked to being unlocked with respect to the carrier service.

Abstract: A method for tracing an inventory item from an inventory is provided. In one example, the method includes: obtaining a single SKU and assigning the single SKU to an inventory item of an inventory; generating a single SKU profile for the inventory item according to the single SKU and storing the single SKU profile in an inventory SKU data model, the single SKU profile including a number of the single SKU and an inventory location of the single SKU; generating an inventory record according to the single SKU and storing the inventory record in the inventory SKU data model; identifying the inventory item according to the number and location of the single SKU, based on an instruction for order fulfillment; and tracking the inventory item according to the single SKU to determine an inventory status change thereof and recording the inventory status change in the inventory record.

Abstract: A double block valve and a valve proving system are disclosed. The double block valve is actuated by a single actuator and includes a valve body housing a cavity. The cavity defines an upstream portion with a fluid inlet and a downstream portion with a fluid outlet. A seating assembly is interposed between the upstream and the downstream portions. A first and a second blocking element are disposed in the valve body and are both movable within the cavity between opened and closed positions. With the first and second blocking elements both contacting the seating assembly, the space therebetween defines an enclosed space with a finite volume. The proving system is used for two safety shut-off valves on a valve train, such as a double block valve. The proving system connects to an enclosed space established between the two safety shut-off valves and includes a pair of three-way valves, oppositely biased pressure switches, and a pump, all of which are interconnected through pneumatic conduits.
