71 results about "Marshalling" patented technology

In computer science, marshalling or marshaling is the process of transforming the memory representation of an object to a data format suitable for storage or transmission, and it is typically used when data must be moved between different parts of a computer program or from one program to another. Marshalling is similar to serialization and is used to communicate to remote objects with an object, in this case a serialized object. It simplifies complex communication, using composite objects in order to communicate instead of primitives. The inverse of marshalling is called unmarshalling (or demarshalling, similar to deserialization).

System and method for generation of user advisories using generative ai in contract analysis

PCT designated stage expiredWO2025090887A2Semantic analysisBiological modelsRisk levelMarshalling
A system, apparatus and method for contract classification processes both primary contracts and their associated documents using context window marshalling. The computing device receives and segments each contract document into contextual chunks based on semantic boundaries, maintaining coherent meaning. A marshalling queue processes chunks sequentially, storing processed data within defined context windows, cross-references between chunks, and a running context buffer of key elements. This chunking and storing process repeats until all associated contract documents are processed. The system identifies parties and contract categories by aggregating information across processed chunks from all related documents, then determines risk parameters using a classifier that considers contractual elements, cross-document relationships, and contextual importance weights. Risk recommendations are calculated based on these parameters, identified parties, class categories, and aggregate metrics computed across document and chunk boundaries. The system ranks contracts by evaluating both individual chunk risks and whole-contract assessment, weighting risks based on contextual significance and inter-chunk dependencies across all related documents. Change recommendations are generated that correlate contractual elements with risk levels, identify high-risk chunks and their relationships, and suggest modifications considering cross-document impacts. This approach enables processing of contracts and their associated documents that exceed single context window limitations while maintaining semantic coherence and relationship preservation throughout the entire document collection.

Smart functionality for discrete field devices and signals

A set of discrete input / output (I / O) channels for one or more field devices may be grouped, organized, and connected to a field module device, which may connect to an electronic marshalling apparatus in a marshalling cabinet via an I / O channel. The field module acts as an intermediary, decoding messages received via the I / O channel to identify commands for discrete output (DO) channels that are then forwarded appropriately. The field module may also receive variable values carried by signals on discrete input (DI) channels and encode the values to a message that may be transmitted to the marshalling apparatus and controller, thus making the variable values on the DI channels available to the controller. The field module may store a profile including information that facilitates various smart commissioning techniques, including autosensing of tags, automatic tag binding, and automatic configuration of a control element corresponding to the field module.
