Publication number: 20220387205Abstract: A powered device augments a joint function of a human during a gait cycle using a powered actuator that supplies an augmentation torque, an impedance, or both to a joint. A controller estimates terrain slope and modulates the augmentation torque and the impedance, according to a phase of the gait cycle and the estimated terrain slope to provide at least a biomimetic response. The controller may also modulate a joint equilibrium. Accordingly, the device is capable of normalizing or augmenting human biomechanical function, responsive to a wearer's activity, regardless of speed and terrain, and can be used, for example, as a knee orthosis, prosthesis, or exoskeleton.Type: ApplicationFiled: August 19, 2022Publication date: December 8, 2022Inventors: Zhixiu Han, Christopher Williams, Jeff Anthony Weber, Christopher Eric Barnhart, Hugh M. Herr, Richard James Casler, JR.

Patent number: 11382773Abstract: In a powered actuator for supplying torque, joint equilibrium, and/or impedance to a joint, a motor is directly coupled to a low-reduction ratio transmission, e.g., a transmission having a gear ratio less than about 80 to 1. The motor has a low dissipation constant, e.g., less than about 50 W/(Nm)2. The transmission is serially connected to an elastic element that is also coupled to the joint, thereby supplying torque, joint equilibrium, and/or impedance to the joint while minimizing the power consumption and/or acoustic noise of the actuator.Type: GrantFiled: November 2, 2018Date of Patent: July 12, 2022Assignee: Otto Bock Healthcare LPInventors: Hugh Miller Herr, Jeff Anthony Weber, Richard James Casler, Jr.

Patent number: 8781779Abstract: An improved method and apparatus for automatically aligning probe pins to the test or bond pads of semiconductor devices under changing conditions. In at least one embodiment, a dynamic model is used to predict an impact of changing conditions to wafer probing process. This reduces the need for frequent measurements and calibrations during probing and testing, thereby increasing the number of dice that can be probed and tested in a given period of time and increasing the accuracy of probing at the same time. Embodiments of the present invention also make it possible to adjust positions of probe pins and pads in response to the changing conditions while they are in contact with each other.Type: GrantFiled: November 9, 2012Date of Patent: July 15, 2014Assignee: FormFactor, Inc.Inventors: Richard James Casler, Jr., Fenglei Du, Stephen Craig Fullerton
