Patent number: 11931271Abstract: A prosthetic foot includes a foot portion and a switching adapter. The switching adapter includes a first member coupled to the foot portion, a second member, a third member interposed between the first member and the second member, and a locking mechanism. The third member has a first side wall and a second side wall larger in length than the first side wall. The third member is configured to rotate relative to the first member and the second member towards a first position, thereby placing the prosthetic device in a walking mode. The third member is further configured to rotate relative to the first member and the second member towards a second position, thereby placing the prosthetic device in a running mode. The locking mechanism is configured to rotate with the third member in response to rotation of the third member.Type: GrantFiled: February 1, 2022Date of Patent: March 19, 2024Assignee: Liberating Technologies, Inc.Inventors: Benjamin Bokser, Kevin Keough, Aaron Taszreak, Todd Farrell, Jennifer Johansson, Sangwoo Park, Kevin Lawrence

Patent number: 11672677Abstract: A system and method for transmission of a signal for a powered assistive device has a sensor node with a wireless transmitter adapted for digitally transmitting a transmitted signal, the sensor node adapted for receiving and monitoring a sensor signal from a sensor attached to a user, and a master node with a controller and a wireless receiver for receiving the transmitted signal from the wireless transmitter. The master node processes the transmitted signal and communicates a control signal to the powered assistive device. The wireless transmitter transmits the transmitted signal at a first rate when the wireless transmitter adapted to transmit the transmitted signal at a first rate when the sensor signal is indicative of the rest state and to transmit the transmitted signal at a second rate when the sensor signal is indicative of the active state, the second rate being greater than the first rate.Type: GrantFiled: October 22, 2021Date of Patent: June 13, 2023Assignee: LIBERATING TECHNOLOGIES, INC.Inventors: Benjamin Edward McDonald, Todd Richard Farrell, Edward Clancy, Jianan Li, Xinming Huang

Publication number: 20170325975Abstract: A prosthetic socket cooling system and method includes a strap for coupling about a limb fitted with a prosthetic socket. One or more thermally conductive heat spreaders are associated with the strap and may be at least partially seated underneath the prosthetic socket. A heat extraction subsystem is coupled to at least one of the lengthy heat spreaders and carried by the strap. In one version, heat spreaders may form sections of the strap.Type: ApplicationFiled: May 9, 2017Publication date: November 16, 2017Applicants: Liberating Technologies, Inc.Inventors: Kristen LeRoy, Ian Cohen, Gordon B.
