  • Publication number: 20250029058
    Abstract: A refrigerating appliance includes a cabinet having an inner liner that defines at least one aperture for accessing a refrigerating compartment. A door is operably coupled to the cabinet and is operable between open and closed positions. A plurality of storage surfaces is positioned within the refrigerating compartment. Each storage surface is adapted to receive at least one temporarily stored item. A scanning apparatus is adapted to record data related to the storage surfaces and the at least one temporarily stored item. The scanning apparatus conducts first and second data capturing phases. The secondary data recorded during the second data capturing phase is compared against previous data recorded during the first data capturing phase to create a current inventory manifest. The current inventory manifest is compared with a set of predetermined parameters related to the at least one temporarily stored item to selectively provide an output.

  • Publication number: 20240419230
    Abstract: A power management system is provided for powering a primary group of power consumers and a secondary group of power consumers. The primary group of power consumers include a data center including a plurality of first computing units. The secondary group of power consumers include a plurality of second computing units whose power consumption is adjustable to ensure the first computing units are continuously powered. The first computing units are in communication with a network for providing cloud services to remote client computers. The first computing units have an energy priority over the second computing units. The power management system includes power sources including a first power source and a second power source. The second power source is a power generation module configured to consume natural gas and continuously generate an electrical output sufficient to alternatively power the plurality of first computing units and the second computing units.

  • Patent number: 11964751
    Abstract: A load detent assembly for restricting creep of a rotating assembly of an actuator used to actuate an aircraft flight control surface. The load detent assembly includes an engagement member having circumferentially spaced engagement surfaces/protruding portions, and a load detent having a stoppage member radially biasable towards the engagement member for interengagement between the engagement surfaces to restrict creep of the rotating assembly. One of the engagement member or the load detent is configured for rotation radially inward of the other of the engagement member or the load detent through at least 360 degrees of rotation. The other of the engagement member or the load detent is configured for being fixed radially outward of the one of the engagement member or the load detent.
