Abstract: A system is provided for enhancing data fields within exchangeable structured data files of property listings. The system includes a server connected to a property management system via a wide area network. The server comprises a processor executing controllers, including a data extraction and parsing controller that identifies incomplete data fields and extracts contextual data. A data enhancement controller interacts with a natural language processing sub-controller and a large language model sub-controller to generate and process queries, populating the incomplete data fields. The system also includes a data pass-back controller that transmits the enhanced structured data files back to the property management system. The system automates the identification, enhancement, and updating of data fields, improving the accuracy and completeness of property listings.

Abstract: A flexible liquid detection sensor is provided comprising a flexible dielectric sheet. A detection field, formed from a pair of conductive traces overlies a first surface of the flexible dielectric sheet, having a resistance responsive to a liquid overlying the conductive traces. The conduction field has an impedance characteristic independent of the selected length of the dielectric sheet. Therefore, the sensor can be cut to almost any length, without the sensor length impacting the liquid sensing resistance measurements. In one aspect, conventional electrical wires can be soldered to the traces to form an electrical interface with the monitoring and alarm equipment. Alternately, the connector may include a clamping mechanism to physically secure the connector to the flexible dielectric sheet, along with an electrical interface that includes pins, to at least partially penetrate the dielectric sheet and engage the conductive traces, in response to securing the clamping mechanism.

Abstract: A 3D liquid detection sensor, liquid-sensitive building material, and liquid detection systems have been provided. The 3D sensor comprises a 3D liquid detection field and an electrical connector to supply a resistance measurement responsive to liquid in the detection field. In one aspect, the 3D liquid detection field includes a first plurality of pins having a distal end electrically connected to a first electrical contact of the electrical connector, and a second plurality of pins having a distal end electrically connected to a second electrical contact. In one aspect, each pin includes a building material attachment barb attached to a pin proximal end. This permits the sensor to be fixedly mounted in drywall or ceiling tile, for example. More specifically, the 3D detection field may include a dielectric sheet (either rigid or flexible), and electrically conductive traces formed overlying the dielectric sheet, with pins extending from the traces.
