Publication number: 20230201010Abstract: A prosthetic or orthotic device has an elongate frame that houses electronics and an actuator rotatably mounted to the frame. The actuator can rotate in an anterior-posterior direction about a medial-lateral axis and includes magnetorheological (MR) fluid and a coil operable to selectively apply a magnetic field to the MR fluid to vary its viscosity and thereby vary a torsional resistance of the actuator about the medial-lateral axis. The device contains a layered control system that makes use of data collected by the embedded sensors in a prosthetic device for intent recognition, management, and actuator control. The layered control system uses a Luenberger observer for estimating joint velocity and a heuristic torque-setpoint component to control the function of a MR actuated knee prosthesis.Type: ApplicationFiled: December 21, 2022Publication date: June 29, 2023Inventors: Arni Einarsson, Maarten Ganseij, Anna Gudmundsdottir, Atli Orn Sverrisson

Publication number: 20220125607Abstract: A vacuum suspension system includes a foot cover having a heel portion and a pump system located in the heel portion. The pump system includes upper and lower sections arranged to move in an axial direction relative to one another and a pump mechanism operatively connected to and positioned between the upper and lower sections. When the heel portion is loaded in stance the pump mechanism moves from an original configuration in which the volume of a fluid chamber defined by the pump mechanism is zero or near-zero, to an expanded configuration in which the volume of the fluid chamber is increased.Type: ApplicationFiled: January 11, 2022Publication date: April 28, 2022Inventors: Atli Orn SVERRISSON, Larus GUNNSTEINSSON, Gudfinna HALLDORSDOTTIR, Hafsteinn JONASSON, Dadi GRANZ, Dana Stewart MARLIN

Patent number: 11051957Abstract: Systems, devices and methods for control of a prosthetic or orthotic device (POD) based on electromyography (EMG) signals are described. The POD may be a lower or upper limb POD having one or more joints. One or more EMG sensors may detect the EMG signals. The EMG sensors may be external, subcutaneous, intraperitoneal, epimysial, intramuscular, or other types. Control of the POD may be based on EMG and non-EMG signals, such as velocity, acceleration, position, force, etc. Voluntary and/or automatic control may be implemented, for example with voluntary muscle contractions and/or data based on velocity, acceleration, position, force, etc. In some embodiments, the neutral position of an ankle POD is adjusted based on EMG signals.Type: GrantFiled: January 11, 2018Date of Patent: July 6, 2021Assignee: Össur Iceland ehfInventors: Árni Einarsson, Stefán Páll Sigurþórsson, Atli Örn Sverrisson
