Publication number: 20190060091Abstract: 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: ApplicationFiled: October 29, 2018Publication date: February 28, 2019Inventors: Michael GOLDFARB, Jason MITCHELL, Huseyin Atakan VAROL, Brian LAWSON, Don TRUEX

Patent number: 10137010Abstract: Systems and methods for operating autonomous lower limb devices, including at least one adjustable joint and configured for at least supporting a body are provided. A method includes collecting real-time sensor information associated with the autonomous lower limb device. The method also includes receiving, over a communications link, remote data for at least one other lower limb device configured for supporting the body. The method further includes generating control data for transitioning the autonomous lower limb device from a current state in a current finite state model for operating the autonomous lower limb device to a different state in the current finite state model, where the different state is selected based on the real-time sensor information and the remote data.Type: GrantFiled: February 26, 2016Date of Patent: November 27, 2018Assignee: VANDERBILT UNIVERSITYInventors: Michael Goldfarb, Brian Lawson

Patent number: 9305114Abstract: Systems, methods and computer-readable storage media are provided for building long queries utilizing query suggestions and query suggestion entities. Upon receiving at least a portion of a search query, a query suggestion is provided. Upon receiving a selection of the query suggestion, the search query is updated. Prior to executing the updated search query, a user is permitted to edit the updated search query. Query suggestions may be presented in association with query suggestion entity representations. A query suggestion entity is a separate and distinct entity that may initiate performance of an action upon selection. A query suggestion entity representation may comprise various features and information associated with the search query.Type: GrantFiled: December 17, 2012Date of Patent: April 5, 2016Assignee: Microsoft Technology Licensing, LLCInventors: Aaron Chun Win Yuen, Daniel Marantz, James Brian Lawson, Parthasarathy Govindarajen

Publication number: 20130310949Abstract: 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: ApplicationFiled: March 15, 2013Publication date: November 21, 2013Applicant: Vanderbilt UniversityInventors: Michael Goldfarb, Brian Lawson, Atakan Huseyin Varol

Publication number: 20130268090Abstract: 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: March 14, 2013Publication date: October 10, 2013Applicant: Vanderbilt UniversityInventors: Michael Goldfarb, Amanda Shultz, Brian Lawson

Patent number: 7042407Abstract: A radome and a reflector antenna configured to mate with the radome. The radome has a central portion and a surrounding outer portion. The central portion having a radius selected to redirect a reflected component of the transmitted RF signal from the radome to the vertex area of the reflector. The outer portion has a larger radius selected to minimize radiation pattern degradation. RF absorbing material located at the vertex area reduces return loss of the reflector antenna. The radome attaches to the reflector via a plurality of tabs formed proximate the periphery of the radome that correspond to a plurality of cut outs in the periphery of the reflector. When inserted and rotated, the radome secures to the reflector without requiring tools.Type: GrantFiled: August 14, 2003Date of Patent: May 9, 2006Assignee: Andrew CorporationInventors: Junaid Syed, Matthew Lewry, Graeme Thomson, Brian Lawson
