Patent number: 11961043Abstract: An inventory tracking system includes storage modules that hold one or more items. Each item is positionable at locations within the storage modules independent of physical characteristics of the item. Inventory monitoring modules are included to monitor storage modules for adding an item, retrieving an item, consuming of the item, returning an unused item, discarding at least a portion of a consumed item, or combinations thereof. Each act is used to determine information about items utilized in the act, including the location within the storage modules of the items. Each storage module updates a central inventory database about a location of the storage module, a revised inventory of the items stored within the storage modules, or both. The location of the storage modules, the revised inventory of the items stored within the storage modules, or both, is used to order a replenishment of the items held within the storage modules.Type: GrantFiled: May 19, 2022Date of Patent: April 16, 2024Assignee: Omnicell, Inc.Inventors: Anupam Kumar Dattamajumdar, Herbert Lawson Fisher, John Alfred D'Costa, Rupert P. Robin, Brian Richard Arnold, Sanandan Sudhir, Shah Sohil Jayeshbhai

Patent number: 11947605Abstract: A system and method for a patent search and analytics software tool that finds prior art for each claim limitation/element by breaking up claims into individual claim limitations. Once the claims are separated, the system finds the best prior art for each of the individual separate, different claim limitations/elements. Additionally, the software finds the best prior art for entire claims, including non-patent literature (NPL) searching. The system takes into account the limitations of the claim under consideration (query claim of query patent), the text of the art, the link structure of the citation network, and the patent classification and then constructs a network that consists of two types of nodes: (i) the art (patents and non-patent literature) and the (ii) classes of the patent classification. Each art node is linked to all the art nodes that it cites and is linked to all the classification nodes that it belongs to.Type: GrantFiled: October 22, 2021Date of Patent: April 2, 2024Inventors: Erich Lawson Spangenberg, Daniel Lawrence Bork, Pascal Asselot, Brian Joshua Berman, George Karypis

Patent number: 11865723Abstract: An exemplary robotic system includes a plurality of controllable joints and a controller. An exemplary control method provides for controlling the controllable joints by the controller. The control method provides for determining a configuration space for the robotic system and determining a reference movement path within the configuration space. The control method then provides for assigning a plurality of streamlines in the configuration space to yield a flow field based on the reference movement path. The control method then provides for measuring actual velocity vectors of the robotic system in the configuration space. The control method then provides for determining an error velocity vector based on a difference between the actual velocity vector and the desired velocity vector given by the flow field corresponding to the current robot configuration.Type: GrantFiled: April 30, 2019Date of Patent: January 9, 2024Assignee: Vanderbilt UniversityInventors: Michael Goldfarb, Andres Martinez-Guerra, Brian Lawson

Patent number: 11666463Abstract: Systems and methods of operating a lower limb device having at least a powered joint are provided. A method includes configuring the device to a first state in a finite state model for a current activity mode including a stair ascent mode or a stair descent mode. The method also includes, based on real-time sensor information, transitioning the device between different states in the finite state model when pre-defined criteria for transitioning among the different states are met. In the method, the finite state model for stair ascent includes lifting and swing phases, where the lifting phase includes a powered knee extension and a powered ankle push-off. The finite state model for stair descent includes yielding and swing states, where the swing states include providing a powered plantarflexion of the powered ankle joint and the yielding states include providing a resistive and passive plantarflexion of the powered ankle joint.Type: GrantFiled: October 12, 2021Date of Patent: June 6, 2023Assignee: Vanderbilt UniversityInventors: Michael Goldfarb, Brian Lawson, Atakan Huseyin Varol

Publication number: 20220331130Abstract: Systems and methods for a running controller for a lower limb device including at least a powered knee joint are provided. The method includes collecting real-time sensor information for the lower limb device and configuring the lower limb device to a first state in a finite state model for an activity mode including the running mode. The method further includes, based on the sensor information, transitioning the lower limb device from a current state to a subsequent state in the finite state model for the detected mode when a pre-defined criteria for transitioning to the subsequent state is met, and repeating the transitioning until the activity mode changes. In the system and method, the finite state model includes at least one stance state and at least one swing state, where the at least one stance state includes at least one absorption state and at least one propulsion state.Type: ApplicationFiled: April 28, 2022Publication date: October 20, 2022Inventors: Michael GOLDFARB, Amanda Shultz, Brian Lawson

Patent number: 11213408Abstract: An asymmetric linear actuator is provided which integrates a hydraulic dissipater and an electric motor and power screw which generates small forces. The actuator is configured so that an electric motor drives a power screw which drives a rod through a cylinder to provide linear actuation. The cylinder is fluid-filled and incorporates a piston that separates the cylinder into a first and second fluid chamber which are filled with a first and second volume of working fluid. Movement of the piston and rod assembly results in fluid movement between the first and second volumes of working fluid and through the fluidic restriction. The fluidic restriction can be proportionally controllable via an electric motor which enables controllable power dissipation via control of the fluidic restriction motor and controllable power generation via control of the power screw motor.Type: GrantFiled: January 8, 2021Date of Patent: January 4, 2022Assignee: Vanderbilt UniversityInventors: Michael Goldfarb, Harrison Bartlett, Brian Lawson

Patent number: 10959862Abstract: A device includes a first member and a second member disposed in series along a longitudinal axis. The device also includes links coupling first joints of the first member to second joints of the second member. The first and second members and the links arranged to define a planar parallelogram linkage. The devices also include a resilient element disposed between the first member and the second member, the first member and the second member preloaded against the resilient element. The first member and the second member are preloaded to provide an arrangement of the first and the second joints in which a motion of the first joints with respect to the second joints is constrained to a direction substantially parallel to the longitudinal axis. The devices further include a sensor for generating a signal indicating a separation between the first member and the second member.Type: GrantFiled: October 29, 2018Date of Patent: March 30, 2021Assignee: Vanderbilt UniversityInventors: Michael Goldfarb, Jason Mitchell, Huseyin Atakan Varol, Brian Lawson, Don Truex
