摘要:
Systems and methods for a running controller for a lower limb device including at least a powered knee joint are provided. The method includes collecting real-time sensor information for the lower limb device and configuring the lower limb device to a first state in a finite state model for an activity mode including the running mode. The method further includes, based on the sensor information, transitioning the lower limb device from a current state to a subsequent state in the finite state model for the detected mode when a pre-defined criteria for transitioning to the subsequent state is met, and repeating the transitioning until the activity mode changes. In the system and method, the finite state model includes at least one stance state and at least one swing state, where the at least one stance state includes at least one absorption state and at least one propulsion state.

Systems and methods of operating a lower limb device having at least a powered joint are provided. A method includes configuring the device to a first state in a finite state model for a current activity mode including a stair ascent mode or a stair descent mode. The method also includes, based on real-time sensor information, transitioning the device between different states in the finite state model when pre-defined criteria for transitioning among the different states are met. In the method, the finite state model for stair ascent includes lifting and swing phases, where the lifting phase includes a powered knee extension and a powered ankle push-off. The finite state model for stair descent includes yielding and swing states, where the swing states include providing a powered plantarflexion of the powered ankle joint and the yielding states include providing a resistive and passive plantarflexion of the powered ankle joint.

Systems and methods for controlling jointed mechanical devices are is provided, where the device is controlled based on a topographic state (300) map having one or more motion axes (D1, D2) and defining a plurality of poses and a plurality of transitions in parallel with one of the motion axes, In the map, each motion axis is associated with complementary types of motion in the device and each of the transitions associated with at least two of the poses. A method includes the steps of receiving a control signal and determining a mechanical state of the device within the topographic state map. The method further includes identifying potential transitions associated with the mechanical state based on the topographic state map. The method also includes adjusting the mechanical state based on the control signal if the control signal is associated with a type of motion associated with one of the identified transitions.

A surgical probe includes an articulated digit located at a distal end of a positioning shaft having a longitudinal axis. An actuator is located at a proximal end of the positioning shaft that is operatively connected to the articulated digit so as to move it between a continuous range of positions from an extended position to a substantially curved position while maintaining a kinesthetic relationship between a surgeon's finger engaging the actuator and the articulated digit. Preferably, the surgeons finger position and shape directly correspond to the position and shape of the articulated digit. A method is provided for probing, dissecting, and retracting anatomical structures.

An apparatus for a collar 12 incorporating various decorative elements used to personalize the collar having means for mounting a behavioral modification apparatus 22 thereto. The collar 12 has at least one aperture 30 for the passage therethrough of the behavioral modification electrode(s) 26 along with means for releasably securing the behavioral apparatus whereby the user can vary or replace the collar. While the collar 12 is designed to incorporate a receptacle for known behavioral modification apparatuses 22, it can also be used for various other products without departing from the concept of providing a receptacle 14 for the placement therein of a behavioral modification apparatus, the receptacle forming an integral part of a strap 12 having one of a mating closure member 18 positioned on each distal end and a ring-like fastener 16 for mounting accessory elements usually associated with pets such as license, identification and contact information.
