Publication number: 20240115403Abstract: A prosthetic knee can include a variable-torque magnetorheological (MR) actuator assembly or braking system, a frame and an electronics assembly or system that also serves as a mount for the knee actuator and facilitates in monitoring and controlling the operation of the knee actuator. The prosthetic knee system advantageously provides resistive forces to substantially simulate the position and motion of a natural knee joint during ambulation and/or other locomotory activities performed by the amputee. The prosthetic knee can be enclosed in a waterproof compartment. An outer cover can be configured to fit around the waterproof cover of the prosthetic knee.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Inventors: David Landry, Gudni Ingimarsson, Gunnar Omar Lillie Magnusson, Lucas Ikelaar, Sylvain Gagné, Kristin Asa Thorisdottir

Publication number: 20230262851Abstract: A sensor for measurements of thermophysical properties having an electrically conductive heating element provided in a circular shape on a base. The electrically conductive heating element is provided on the base in a pattern that is designed to better approximate a perfect circle so that the sensor better represents a circular solid disk source as described in the thermal equations used for measuring thermophysical properties, and thus requires a smaller empirical correction, improving the accuracy and certainty of measurements. The pattern of the electrically conductive heating element on the base is designed to optimize uniformity of heat distribution, thereby avoiding hot spots and, where hot spots are unable to be avoided, evenly distributes such hot spots.Type: ApplicationFiled: February 13, 2023Publication date: August 17, 2023Inventors: Dale Hume, Keegan Copage, David Landry

Patent number: 10643038Abstract: Techniques for monitoring objects being placed onto a plurality of pallets. A controller is configured to analyze images captured by the plurality of camera devices to determine when a first object is placed onto a first one of the plurality of pallets. Upon determining that the first object has been placed onto the first pallet, the controller can determine a first identifier corresponding to the first object using the RFID reader corresponding to the first pallet and can determine an intended pallet corresponding to the first object. Upon determining that the first pallet onto which the first object was placed is not the intended pallet for the first object, the user is notified using the feedback mechanism.Type: GrantFiled: February 9, 2018Date of Patent: May 5, 2020Assignee: Amazon Technologies, Inc.Inventors: David Bruce McCalib, Jr., Oleg Kantor, Joshua David Landry, Sr., Tak Keung Joseph Lui

Patent number: 10460137Abstract: A method of interrogating a plurality of RFID tags comprises interrogating a first RFID tag with a read command comprising a masking value for a predefined portion of a User Memory Bank of the first RFID tag. The predefined portion stores state information for the first RFID tag. The masking value corresponds to a non-quiesced state relative to the read command interrogation. The method further comprises receiving a response from the first RFID tag that indicates that the first RFID tag is in the non-quiesced state. The method further comprises interrogating the first RFID tag with a write command that instructs the first RFID tag to write a predefined value to the predefined portion of the User Memory Bank, wherein writing the predefined value to the predefined portion places the first RFID tag in a quiesced state relative to a subsequent read command interrogation comprising the masking value.Type: GrantFiled: February 7, 2018Date of Patent: October 29, 2019Assignee: Amazon Technologies, Inc.Inventors: Joshua David Landry, Sr., Christopher Raymond Grajewski, Oleg Kantor, Tak Keung Joseph Lui, David Bruce McCalib, Jr., Roman Shmulevich, Alton Paul Werronen, Fabien Lepoutre, Mark G.

Publication number: 20190115202Abstract: An opposed dipole magnet assembly is provided that exhibits higher magnetic field uniformity than traditional magnet assemblies, such as H-shaped magnet assemblies. The opposed dipole magnet assembly includes two permanent magnets that are spaced apart and oriented such that their respective magnetization directions are parallel. Plates formed of a high permeability material are attached to top and bottom surfaces of the two permanent magnets so as to form a hollow field region. With this geometry, the magnetic field in the hollow field region is in a direction antiparallel to the magnetic field directions of the two permanent magnets.Type: ApplicationFiled: November 30, 2018Publication date: April 18, 2019Inventors: Jason J. AMSDEN, Jeffrey T. GLASS, Charles B. PARKER, Michael E. GEHM, Zach RUSSELL, David LANDRY, Shane DI DONA

Patent number: 9730824Abstract: A high torque active mechanism for an orthotic and/or prosthetic joint using a primary brake which can be provide by magnetorheological (MR) rotational damper incorporating and an additional friction brake mechanism driven by the braking force generated by the MR damper. This combination of MR damper and friction brake mechanism allows an increase in torque density while keeping the same level of motion control offered by the MR damper alone. The increased torque density achieved by this high torque active mechanism allows to minimize the size of the actuating system, i.e. its diameter and/or breath, while maximizing its braking torque capability. In this regard, the friction brake mechanism is advantageously positioned around the MR damper, such that the dimension of the package is minimized.Type: GrantFiled: May 22, 2015Date of Patent: August 15, 2017Assignee: Victhom Laboratory Inc.Inventors: Benoit Gilbert, David Landry
