Publication number: 20240122347Abstract: A mechanism for a seating unit is provided that allows a reclining mechanism to freely rock on a rocker assembly when a locking actuator is in a first position, and that provides an auto-rocking motion, via a rocking actuator, when the locking actuator is in a second position.Type: ApplicationFiled: October 9, 2023Publication date: April 18, 2024Applicant: L&P Property Management CompanyInventors: David FORGY, Ronald D. DAVIS, David PURSER, Tony DIGGS, Caleb BROWNING

Patent number: 11517109Abstract: A motorized positioning apparatus for a seating unit includes a motor assembly that is configured to move a pair of linkage mechanisms though a series of positions that arrange the seating unit in a closed position, open position, or extended position. The motor assembly is selectively and releasably coupled to the linkage mechanisms, to allow the motor assembly to be de-coupled from the linkage mechanisms to allow the seating unit to be manually closed by a user.Type: GrantFiled: March 30, 2020Date of Patent: December 6, 2022Assignee: L&P PROPERTY MANAGEMENT COMPANYInventors: Caleb Browning, Ronald D. Davis, Randy Ford, Vino Gopalakrishnan, David Purser

Patent number: 11259641Abstract: Aspects herein are directed to systems and methods for synchronization of actuators to reposition furniture units. Specifically, a master control box receives input to reposition a furniture unit from one position to another and communicates the input to a plurality of control boxes. Then, each of the plurality of control boxes assigns a virtual axis to each of a plurality of actuators attached to each associated control box. Furthermore, each of the plurality of control boxes assigns a transfer function to each of the plurality of actuators. The transfer function is used by the actuators to transform an output of the virtual axis to determine a target position. In this way, the plurality of actuators can reference the same virtual axis for synchronization purposes, but use different transfer functions to maintain complex relationships between the positions of each actuator. Based on the target position, the actuators reposition the furniture unit.Type: GrantFiled: January 21, 2020Date of Patent: March 1, 2022Assignee: L&P Property Management CompanyInventors: Oliver J. Schramm, David Purser, Ronald D. Davis, Caleb Browning

Patent number: 7658526Abstract: An illumination system includes a plurality of radiation generating sources, such as LED dies. A corresponding plurality of optical waveguides is also provided, with each waveguide having a first and a second end, with each first end being in optical communication with the corresponding LED die. An array of corresponding passive optical elements is interposed between the plurality of LED dies and the corresponding first ends of the plurality of optical waveguides. The illumination system provides for substantially high light coupling efficiency and an incoherent light output that can appear to the human observer as arising from a single point of light. In addition, the light can be output remotely at one or more locations and in one or more directions.Type: GrantFiled: March 12, 2008Date of Patent: February 9, 2010Assignee: 3M Innovative Properties CompanyInventors: Gordon D. Henson, Barbara A. DeBaun, Michael A. Meis, John C. Schultz, John J. Simbal, Ronald D. Davis
