Publication number: 20240107748Abstract: Methods, systems, and devices for staggered horizontal cell architecture for memory devices are described. Generally, the described techniques provide for a memory device that supports staggered cell architectures and techniques to manufacture the memory device. The memory device may include a stack of materials including alternating layers of dielectric and conductive material. The memory device may include one or more staircase structures coupled with the stack of layers. The memory device may include access lines, such as bit lines, that are staggered according to a pattern, such as a serpentine pattern of dielectric fill surrounding the access lines. The memory device may include a set of repeatable structures that may be interlaced in a staggered configuration. The repeatable structure may include two fins extending in opposite directions and coupled to a respective staircase structure.Type: ApplicationFiled: September 27, 2022Publication date: March 28, 2024Inventors: William M.

Patent number: 10967313Abstract: A filter cartridge for operatively coupling to an appliance interface to treat a fluid, such as water, being supplied to the appliance. The interface comprises a bypass valve for actuating the interface between a bypass mode in which the fluid flowing through the interface does not flow through the filter cartridge and a treatment mode in which the fluid flowing through the interface is directed through the filter cartridge for treatment by the filter cartridge. The filter cartridge comprises a cartridge housing having a first end and a second end and extending along a housing longitudinal axis through the first end and the second end. A filter media is contained within the cartridge housing between the first end and the second end. The filter cartridge also has a first end cap on the first end of the cartridge housing and a second end cap on the second end of the cartridge housing. A bypass valve actuator is attached to the cartridge housing and extends distally to an actuator distal end.Type: GrantFiled: November 27, 2019Date of Patent: April 6, 2021Assignee: Whirlpool CorporationInventor: Christopher M. Campbell

Patent number: 10584040Abstract: A filter cartridge for operatively coupling to an appliance interface for treating fluid to the appliance. The filter cartridge includes a cartridge housing and a filter media contained within the cartridge housing. An engagement fitting extends from the cartridge housing. The engagement fitting to be received by the interface. The engagement fitting includes a base portion and a sealing member. The base portion has an inlet aperture on a first side of the sealing member and an outlet aperture on a second side of the sealing member. An interference member actuator extends axially and distally from one of the first end of the cartridge housing and the first end cap. The interference member actuator is configured to actuate an interference member of the interface from an interference position in which the interface is prevented from being actuated from a bypass mode to a filtering mode to a non-interference position.Type: GrantFiled: October 6, 2017Date of Patent: March 10, 2020Assignee: Whirlpool CorporationInventor: Christopher M.
