20100038983 | ACTUATOR SYSTEM WITH A MOTOR ASSEMBLY AND LATCH FOR EXTENDING AND FLEXING A JOINT - One of the embodiments of the invention is an actuator system for extending and flexing a joint. The actuator system includes a multi-motor assembly for providing a rotational output, a rotary-to-linear mechanism including a screw that accepts the rotational output of the multi-motor assembly and a nut that cooperates with the screw to convert rotational movement of the screw to linear movement of the nut, and a moving rail with a latch that functions to translate linear movement of the nut in both the extension and flexion directions into an extension and flexion of the joint. The actuator has been specifically designed for extending and flexing a joint (such as an ankle, a knee, an elbow, or a shoulder) of a human. The actuator system may, however, be used to move any suitable object through any suitable movement (linear, rotational, or otherwise). | 02-18-2010 |
20100198124 | SYSTEM AND METHOD FOR CONTROLLING THE JOINT MOTION OF A USER BASED ON A MEASURED PHYSIOLOGICAL PROPERTY - In one embodiment, the apparatus for controlling the motion of a joint of a user includes a physiological sensor that measures a physiological property of the user, an orthosis that controls the motion of the joint of the user, an orthosis sensor that monitors a physical property of the orthosis, and a processing unit that processes data from the physiological sensor and from the orthosis sensor. In another embodiment, the method for controlling the motion of a joint of a user includes measuring a physiological property of the user with a physiological sensor, controlling motion of the joint of the user with an orthosis, monitoring a physical property of the orthosis with an orthosis sensor, and processing data from the physiological sensor and from the orthosis sensor. | 08-05-2010 |
20130289452 | EXOSKELETON FOR GAIT ASSISTANCE AND REHABILITATION - A method of operating an exoskeleton device includes: receiving sensor information; connecting a clutch system to a pulley system in; determining whether to engage a drive train gear to the clutch system based on the sensor information; engaging the drive train gear through the clutch system when determined to engage the drive train gear; and powering a first motor to drive the drive train gear for controlling a joint or segment of exoskeleton device. | 10-31-2013 |

20090204038 | MULTI-FIT ORTHOTIC AND MOBILITY ASSISTANCE APPARATUS - A multi-fit orthotic structure including an attachment system for coupling the orthotic structure to a wide variety of subjects without requiring a custom fit. In one embodiment, active mobility assistance is provided via an orthotic system capable of integrating a linear actuator and linkage system to deliver torque to the lower leg of a subject to facilitate flexion and/or extension motion of the subject's leg. The orthotic structure is attached to the subject using a textile suspension system which does not require the orthotic structure to interface directly in the knee region or at the lateral areas of the thigh and calf of the subject, thus providing an ideal fit for the widest possible range of subjects with the minimum number of required sizes. | 08-13-2009 |
20100039052 | ACTUATOR SYSTEM WITH A MULTI-MOTOR ASSEMBLY FOR EXTENDING AND FLEXING A JOINT - An actuator system for extending and flexing a joint, including a multi-motor assembly for providing a rotational output, a rotary-to-linear mechanism for converting the rotational output from the multi-motor assembly into an extension and flexion of the joint, and a controller for operating the actuator system in several operational modes. The multi-motor assembly preferably combines power from two different sources, such that the multi-motor assembly can supply larger forces at slower speeds (“Low Gear”) and smaller forces at higher speeds (“High Gear”). The actuator has been specifically designed for extending and flexing a joint (such as an ankle, a knee, an elbow, or a shoulder) of a human. The actuator system may, however, be used to move any suitable object through any suitable movement (linear, rotational, or otherwise). | 02-18-2010 |

20120316475 | ACTUATOR SYSTEM WITH A MOTOR ASSEMBLY AND LATCH FOR EXTENDING AND FLEXING A JOINT - An actuator system for assisting extension of a biological joint is provided with a motor assembly, a rotary-to-linear mechanism, and an extension stop. The rotary-to-linear mechanism includes a screw that accepts rotational output of the motor assembly, and a nut that cooperates with the screw to convert rotational movement of the screw to linear movement of the nut. The extension stop is driven by linear movement of the nut in an extension direction to cause extension of the biological joint. The motor assembly, the rotary-to-linear mechanism and the extension stop cooperate to allow unpowered flexion of the joint. The system is configured without a flexion stop, and is configured such that the nut cannot drive the joint in a flexion direction. Methods of use are also disclosed. | 12-13-2012 |
20130079687 | METHODS AND DEVICES FOR DEEP VEIN THROMBOSIS PREVENTION - Portable devices and methods for preventing deep vein thrombosis (DVT) by assuring that the ankle is flexed and extended sufficiently to promote blood flow in the lower leg are disclosed. The device includes an actuator with a free movement mode that allows a patient to move freely between activations or to initiate movement to delay a next automatic activation. | 03-28-2013 |
20130261511 | THERAPY AND MOBILITY ASSISTANCE SYSTEM - A therapy and mobility assistance system used by a patient that includes a leg device worn on the leg of the patient that provides assistance and/or resistance to enhance the mobility of the leg of the patient, a therapy shuttle that facilitates therapeutic extension and flexion of at least one of the joints of the leg of the patient, and an appendage fastener that selectively couples the therapy shuttle and the leg device. The therapy and mobility assistance system may additionally include a guide track that constrains motion of the therapy shuttle along a path. | 10-03-2013 |
