  • APPARATUSES, METHODS, AND COMPUTER PROGRAM PRODUCTS FOR DATA CONTEXTUALIZATION OF OPERATIONAL TECHNOLOGY ASSETS
    Publication number: 20250086468
    Abstract: A method for classifying assets in a facility includes receiving item point metadata and time series data associated with an asset, applying a machine learning neural network to the item point metadata and time series data to determine a similarity between metadata associated with the asset and metadata associated with a known asset type, and determining that the asset is of the asset type based on the similarity satisfying a predetermined threshold. The neural network comprises anchor-based learning trained on a plurality of mined triplets including an anchor input, a positive input, and a negative input. The neural network is configured to generate vector representations associated with each of the anchor input, the positive input, and the negative input. A loss function applied to the vector representations is configured to differentiate between the vector representation associated with the positive input and the vector representation associated with the negative input.

    Publication number: 20250074158
    Abstract: A cooling arrangement for conditioning air within a cabin of an underground work machine includes blowers to generate an air flow, a first evaporator, and a second evaporator. The first evaporator provides passage to a first portion of the air flow and receive a first coolant to facilitate a first heat transfer from the first portion of the air flow to the first coolant. The second evaporator provides passage to a second portion of the air flow and receive a second coolant to facilitate a second heat transfer from the second portion of the air flow to the second coolant. A receipt of the first coolant into the first evaporator for the first transfer and a receipt of the second coolant into the second evaporator for the second transfer occurs either independently or simultaneously with each other for supplying conditioned air flow into the cabin to cool the cabin.

  • Service architecture for ontology linking of unstructured text
    Patent number: 12242525
    Abstract: Techniques for ontology linking of unstructured text as a service are described. A service may receive a request to link unstructured text to a standardized ontology, and the service may segment and tokenize the unstructured text and send the result to multiple services implementing multiple deep machine learning models trained to identify particular entities and one or more relationships between entities. The service may perform a search of the standardized ontology to identify a set of similar candidates from the standardized ontology for the detected entities and the one or more relationships, and then rank the set of similar candidates from the standardized ontology according to their similarity to the detected entities within the unstructured text. The output from the service may include a result identifying a highest ranked candidate of the set of similar candidates from the standardized ontology for the detected entities within the unstructured text.

  • METHODS AND SYSTEMS FOR EVALUATING ENERGY CONSERVATION AND GUEST SATISFACTION IN HOTELS
    Publication number: 20250027668
    Abstract: A method for determining an energy score for a guest room of a hotel having a plurality of guest rooms includes identifying two or more energy saving conditions associated with the guest room under which there is an opportunity to save energy when controlling the guest room without sacrificing guest comfort. The guest room is controlled in a designated energy savings mode when one or more of the energy savings room conditions are detected, and controlling the guest room in a guest comfort mode when none of the energy savings room conditions are detected. An energy score for the guest room is determined based at least in part on a measure of reliability of detecting the two or more energy savings conditions of the guest room, and thus the ability to take advantage of the opportunities to save energy when controlling the guest room.

  • SYSTEMS AND METHODS FOR VOLUNTARILY PROVIDING BIOMETRIC DATA FOR ANONYMOUS PLAYER TRACKING
    Publication number: 20240029508
    Abstract: Disclosed are methods of operating a casino gaming system to establish a play session for an anonymous player in which the player voluntarily provides biometric information to link the player to a player tracking record in a database of the system. In some embodiments, the player grants permission for a camera integrated into an electronic gaming machine to capture a facial image to assist in the location of the record or creation of a new record associated with the player's biometric signature. In other embodiments, the player voluntarily uses a camera integrated into a personal electronic device, such as the player's smartphone, to capture the facial image. Once the player record to be used has been identified, the record is linked to the electronic gaming machine to create a play session from which player tracking data is collected and integrated into the database record associated with the anonymous player.
