International Classification:

A61H 1/00

US Classification:

601 34

Abstract:

A powered exoskeleton configured to be coupled to lower limbs of a person is controlled to impart a movement desired by the person. The intent of the person is determined by a controller based on monitoring at least one of: positional changes in an arm portion of the person, positional changes in a head of the person, an orientation of a walking aid employed by the person, a contact force between a walking aid employed by the person and a support surface, a force imparted by the person on the walking aid, a force imparted by the person on the walking aid, a relative orientation of the exoskeleton, moveable components of the exoskeleton and the person, and relative velocities between the exoskeleton, moveable components of the exoskeleton and the person.

International Classification:

A61H 1/00

US Classification:

601 34

Abstract:

A system and method by which movements desired by a user of a lower extremity orthotic is determined and a control system automatically regulates the sequential operation of powered lower extremity orthotic components to enable the user, having mobility disorders, to walk, as well as perform other common mobility tasks which involve leg movements, perhaps with the use of a gait aid.

International Classification:

A61F 2/68

US Classification:

623 24

Abstract:

A powered lower extremity orthotic, including a shank link coupled to an artificial foot, a knee mechanism connected to the shank link and a thigh link, is controlled by based on signals from various orthotic mounted sensors such that the artificial foot follows a predetermined trajectory defined by at least one Cartesian coordinate.

Tim Swift - Walnut Creek CA, US

International Classification:

A61H 3/00
B25J 9/00
A61H 1/02

Abstract:

A method of performing a fit test on an actuator unit coupled to a user. The method includes actuating the actuator unit; determining a first configuration of the actuator unit generated during the actuating the actuator unit; determining a second configuration of the actuator unit generated during the actuating the actuator unit; determining a change in configuration of the actuator unit based at least in part on the difference between the first and second configuration; and determining that the change in configuration corresponds to an improper fit of the actuator unit to the user.

A61H 1/02

Abstract:

A method of performing a fit test on an actuator unit coupled to a user. The method includes determining a first configuration of the actuator unit generated in response to actuating the actuator unit while the user is performing one or more movements for the fit test; determining a change from the first configuration of the actuator unit while the user is performing the one or more movements for the fit test; determining that the change from the first configuration corresponds to an improper fit of the actuator unit coupled the user; and generating an improper fit indication that indicates improper fit of at least leg actuator units coupled the user.

Abstract:

A lower-leg exoskeleton that includes an inflatable actuator configured to be worn over a front portion of a leg of a user and configured to be disposed directly adjacent to and surrounding a joint of the leg of the user. The inflatable actuator is configured, when worn by the user, to receive and transmit an actuator load generated by the inflatable actuator around the joint of the user to a load contact point. Inflation of the inflatable actuator generates a moment about the joint of the user to cause flexion of the leg of the user.

International Classification:

A61H 3/00
B25J 9/00

Abstract:

A method of performing a fit test on an actuator unit coupled to a user. The method includes determining a first configuration of the actuator unit while the actuator unit is in an un-actuating state and while the user is in a fit test position; actuating the actuator unit; determining a second configuration of the actuator unit generated in response to the actuating the leg actuator unit; determining a change in configuration of the actuator unit based at least in part on the difference between the first and second configuration; and determining that the change in configuration corresponds to an improper fit of the actuator unit to the user.
