Patent number: 10369022Abstract: A control system for control of a prosthetic device having a plurality of actuators receives an orientation signal indicative of a desired movement. The control system evaluates whether the prosthetic device may move as desired with a current angle of rotation and commands at least one actuator to move the prosthetic device as desired by maintaining the current angle of rotation or by adjusting the angle of rotation if the prosthetic device cannot move as desired with the current angle. The control system may alternate between commanding a first subset of actuators and a second subset of actuators each time the orientation signal is indicative of a neutral position. The control system may include a position sensor and a compliance sensor and may command at least one actuator based on a combination of positional control using the position sensor and force control using the compliance sensor.Type: GrantFiled: August 24, 2015Date of Patent: August 6, 2019Assignee: DEKA PRODUCTS LIMITED PARTNERSHIPInventors: Dirk Albertus van der Merwe, Gregory R. Lanier, John M. Kerwin, Gerald M. Guay, N. Christopher Perry, Susan D. Dastous

Patent number: 10302075Abstract: A reciprocating positive displacement pump comprises a flexible diaphragm fluidically separating a pumping chamber from an actuation chamber. The membrane may include bumps or other features on the side of the membrane facing the pumping chamber that space at least a portion of the membrane away from the rigid chamber wall when the membrane is in a minimum-pumping-chamber volume position. Such structures may prevent pockets of fluid from being caught away from the inlet and outlet by keeping portions of the membrane spaced away from the rigid pumping chamber wall even when the pumping chamber volume is at a minimum.Type: GrantFiled: October 27, 2014Date of Patent: May 28, 2019Assignee: DEKA Products Limited PartnershipInventors: Brian D. Tracey, Larry B. Gray, Jason A. Demers, James D. Dale, N. Christopher Perry, Michael J. Wilt, Scott A. Leonard
