  • Publication number: 20260092410
    Abstract: A washing appliance includes a tub positioned within an outer cabinet. A rotating drum rotates within the tub. A fluid flow path directs fluid through the tub and the drum. A rotator selectively rotates relative to the drum to generate at least a toroidal flow of the wash fluid through the drum and a supplemental flow of the wash fluid through a filter assembly positioned within the rotator.

  • Patent number: 12373687
    Abstract: Described herein are techniques of training a machine learning model and performing inference using an analog processor. Some embodiments mitigate the loss in performance of a machine learning model resulting from a lower precision of an analog processor by using an adaptive block floating-point representation of numbers for the analog processor. Some embodiments mitigate the loss in performance of a machine learning model due to noise that is present when using an analog processor. The techniques involve training the machine learning model such that it is robust to noise.

  • Publication number: 20240352653
    Abstract: A laundry appliance includes a cabinet having a top panel that defines an aperture for selectively accessing a treatment chamber defined within the cabinet. A lid is rotationally operable relative to the aperture of the top panel between open and closed positions. Hinge assemblies extend between the lid and the top panel. The hinge assemblies include a first hinge assembly. A second hinge assembly is selectively retractable into the lid to a retracted position. A biasing member biases the second hinge assembly out to an extended position. At least the second hinge assembly is operable to the retracted position to bypass a portion of the top panel to define an installed position where the first and second hinge assemblies are engaged with respective hinge receptacles of the top panel.

  • Patent number: 11866970
    Abstract: A fabric treatment machine has a cabinet housing. A lid enables access inside the cabinet. Fabric treatment components such as a drum are positioned inside the cabinet housing. A panel on the cabinet housing includes an opening to receive the lid. At least one hinge spacer couples with the panel to receive a shaft of a slow close hinge on the lid. The at least one hinge spacer includes a socket portion and a flange portion. The socket portion inserts into an aperture in the panel. The socket portion includes a bore with at least one flat side to receive a mating shaft from the slow closing hinge. The hinge shaft has at least one flat surface. The flange portion covers the panel around the socket.

  • Patent number: 11320188
    Abstract: A refrigerator includes an outer wrapper, a fresh food compartment defined by a liner within the wrapper and separated from an interior of the outer wrapper at least along a first side wall of the fresh food compartment to define a void, and a door at least partially enclosing an opening to the fresh food compartment when in a closed position. A door compartment is positioned along the door. The refrigerator further includes an evaporator compartment positioned at least partially within the fresh food compartment and a duct in fluid communication with the evaporator compartment at a first end thereof and in communication with the door compartment a second end thereof. The duct has a first portion that extends laterally from the first end along a portion of the evaporator compartment and a second portion extending through the void along the first side wall of the fresh food compartment.

  • Patent number: 9339017
    Abstract: A living wave barrier is disclosed. The barrier is made up of a plurality of habitat modules that have cooperating depending footer elements and recesses in the bottom and top sides, respectively. The footer elements are spaced to allow limited free flow of water around the modules. Environmental elements, such as stones and the like, are disposed on the modules to provide a suitable habitat for local aquatic life and further removable elements may be provided to contain oyster spat. The barrier may be attached to an existing pier by way of a throughbore in each of the modules or may stand alone secured on the seabed by a pad. The barrier provides wave attenuation and may also be used to create a recreational area such as a snorkeling park or artificial reef.

  • Patent number: 8800650
    Abstract: An expandable tubular includes a plurality of leaves formed from sheet material that have curved surfaces. The leaves extend around a portion or fully around the diameter of the tubular structure. Some of the adjacent leaves of the tubular are coupled together. The tubular is compressed to a smaller diameter so that it can be inserted through previously deployed tubular assemblies. Once the tubular is properly positioned, it is deployed and coupled or not coupled to a previously deployed tubular assembly. The tubular is useful for all types of wells and boreholes.
