Patent number: 9351854Abstract: A system and method associated with the movement of a limb. In one example, the system, such as a prosthetic or orthotic system, includes an actuator that actively controls, or adjusts, the angle between a foot unit and a lower limb member. The actuator preferably selectively locks during a desired phase in a gait cycle of the limb and minimizes friction against a rotor of the actuator. A processing module may control movement of the actuator based on data obtained from a sensor module. For instance, sensing module data may include information relating to the gait of a user and may be used to adjust the foot unit to substantially mimic the movement of a natural, healthy ankle. The system may further accommodate, for example, level ground walking, traveling up/down stairs, traveling up/down sloped surfaces, and various other user movements. In addition, the processing module may receive user input or display output signals through an external interface.Type: GrantFiled: April 28, 2014Date of Patent: May 31, 2016Assignee: Össur hfInventors: Helgi Jónsson, Arinbjörn Viggo Clausen, Gudni Ingimarsson, Christophe Lecomte, Larus Sigfusson, Heidrún Gígja Ragnarsdöttir

Patent number: 9271851Abstract: Systems and methods for sensing actuating a prosthetic ankle are disclosed. In one example, the system, such as an actuated prosthetic ankle joint, detects that the user has moved to a relaxed position, such as sitting, reclining, crawling, or leaning. In response, the actuated prosthetic ankle joint actively adjusts the angle between the members of the ankle to a relaxed state. The system may further detect when the user has moved to exit the relaxed position, and may actively adjust the angle between the members of the ankle to an exit state.Type: GrantFiled: February 28, 2011Date of Patent: March 1, 2016Assignee: Össur hf.Inventors: Arinbjörn V. Clausen, Heidrun G. Ragnarsdottir, Helgi Jonsson

Publication number: 20150265429Abstract: Control systems and methods are disclosed for processing a time series of signals associated with the movement of a device associated with a limb. The time series of motion signals is filtered, such as thorough an autoregressive filter, and compared to stored data sets representing a limb-motion event and/or phase. In certain examples, a plurality of accelerometers generate the time series of motion signals based at least on acceleration measurements in three orthogonal directions and/or planes. The acceleration measurements may relate to the movement of an artificial limb, such as a prosthetic or orthotic device. Upon determining an event and/or phase of limb motion, the control system may trigger an actuator to appropriately adjust one or more prosthetic or orthotic joints.Type: ApplicationFiled: June 8, 2015Publication date: September 24, 2015Inventors: Helgi Jónsson, Arinbjörn Viggo Clausen, Heidrun G.
