Publication number: 20260092410Abstract: 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.Type: ApplicationFiled: December 8, 2025Publication date: April 2, 2026Applicant: WHIRLPOOL CORPORATIONInventors: Anayancy Campos, James Jeffery, Eric W. Merrow, Sayer J. Murphy, Brian D. Peschke, Erica L. Pinto, Ryan Rutter, Aliander F. Silva, Thomas D. Spicer, Eric J. Vasko, David Walter, Mahendra S. Wankhede, B. Shiva

Patent number: 12373687Abstract: 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.Type: GrantFiled: November 29, 2021Date of Patent: July 29, 2025Assignee: Lightmatter, Inc.Inventors: Darius Bunandar, Ludmila Levkova, Nicholas Dronen, Lakshmi Nair, David Widemann, David Walter, Martin B.

Publication number: 20240352653Abstract: 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.Type: ApplicationFiled: July 3, 2024Publication date: October 24, 2024Applicant: WHIRLPOOL CORPORATIONInventors: James Jeffery, Paula Lobaccaro, Nicholas C.

Patent number: 9339017Abstract: 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.Type: GrantFiled: December 12, 2012Date of Patent: May 17, 2016Inventor: David Walter

Patent number: 8800650Abstract: 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.Type: GrantFiled: March 12, 2007Date of Patent: August 12, 2014Assignee: Dynamic Tubular Systems, Inc.Inventors: Jeffery A.
