  • Publication number: 20250137675
    Abstract: A building system of a building, the building system including one or more memory devices storing instructions thereon that, when executed by one or more processors, cause the one or more processors to update a building condition of an HVAC system of a space in a building at a time t1, wherein the building condition is updated from a default building condition. The instructions when executed by the one or more processors, cause the one or more processors to update the building condition of the space at a time t2 and receive an occupant response of an occupant from the space. The instructions when executed by the one or more processors, cause the one or more processors to update an artificial intelligence (AI) model based on the occupant response and generate, using the AI model, one or more actions for the HVAC system of a plurality of spaces.

  • Patent number: 7860750
    Abstract: An order fulfillment tool may indicate fulfillability information for a plurality of open orders and receive user input specifying one or more orders for potential fulfillment. In response, the order fulfillment tool may indicate revised fulfillability information for orders not specified for potential fulfillment according to the effects on a current inventory if the specified orders were fulfilled. The order fulfillment tool may also recommend orders for potential fulfillment according to user-specified order fulfillment criteria and indicate revised fulfillability information for orders not recommended for potential fulfillment. Such an order fulfillment tool may also receive user input specifying fulfillment levels for individual items of orders and update fulfillability information for other orders according to the effect of the individual fulfillment levels.

  • Patent number: 7822619
    Abstract: One embodiment of the present invention provides a system that provides a context-sensitive “community link,” which enables a system or application user to easily access a community forum related to a specific system or application feature. During operation, the system provides a user with access to the system or application feature. While providing such access, the system displays a community link to the user, wherein the community link is directed to a community forum associated with the system or application feature. When the user selects the community link, the system navigates the user to the community forum associated with the system or application feature, so that the user can exchange information with other users about the system or application feature.

  • Publication number: 20100240102
    Abstract: Disclosed are methods for multiple displacement amplification of a nucleic acid sequence in a sample. The nucleic acid is contacted with a reaction mixture that includes a set of oligonucleotide primers and a plurality of polymerase enzymes. The reaction mixture is subjected to conditions under which the nucleic acid sequence is amplified to produce an amplification product in a multiple displacement amplification reaction. Also disclosed are kits containing a set of oligonucleotide primers with random sequences having lengths of 6 to 8 nucleobases. At least some of the individual members of the primers have one or more ribose modifications that stabilize or lock the ribose ring in a 3? -endo conformation. At least some of the primers have one or more universal nucleobases.
