Patent number: 12380136Abstract: As discussed earlier, labelling techniques that are available for labelling of unlabelled tabular data use some semi supervised models for identification purposes. However, they require sample labeled data for training purposes. Further, the same labelling model/technique cannot be used for all data types. Present disclosure provides method and system for identifying labels of unlabeled column data. The system uses a hybrid approach i.e., it uses language models, regular expressions and known dictionaries for labelling of unlabelled tabular data. For performing labelling, system first classifies received unlabelled tabular data into one or more data buckets. The system then uses appropriate techniques, based on data types, for identification of labels of unlabeled data present in data buckets. Thereafter, system uses feedback mechanism which will impart maturity to system over time. Finally, once system is matured, system can identify labels for all types of data.Type: GrantFiled: July 2, 2024Date of Patent: August 5, 2025Assignee: TATA CONSULTANCY SERVICES LIMITEDInventors: Anantha Desik Puranam Hosudurg, Sumiran Naman, Ashim Roy, Ashish Diwan, Nikhil Girish Patwardhan

Patent number: 12374988Abstract: A fault-responsive power system and method using asynchronous load current switching. A first supply-side current that flows from a power supply into a first conductor, which electrically couples the power supply to a load, is measured. Power is delivered to the load by modulating a first remote-side current on and off, with the remote-side current entering the load from the first conductor. Once it is determined that the first supply-side current has met or exceeded a magnitude threshold for at least a duration threshold, the first supply-side current is reduced such that the first supply-side current is less than the magnitude threshold. A data signal may also be transmitted by embedding a data signal in the first remote-side current through the modulation of the first remote-side current, and demodulating the data signal in the first supply-side current.Type: GrantFiled: March 18, 2022Date of Patent: July 29, 2025Assignee: Equinox Power Innovations Inc.Inventor: Glenn Lumanog
