Semi-powered lower extremity exoskeleton
ActiveUS20070056592A1Drag minimizationProgramme-controlled manipulatorOperating chairsKnee JointEngineering
The lower extremity exoskeleton comprises two leg supports connectable to person's lower limbs and configured to rest on the ground during their stance phase. Each leg support comprises a thigh link and a shank link; a knee joint configured to allow flexion and extension between the shank link and the thigh link. The lower extremity exoskeleton further comprises an exoskeleton trunk connectable to the person'supper body. The exoskeleton trunk is connectable to the thigh links of the leg supports allowing for the flexion and extension between the leg supports and the exoskeleton trunk. Two torque generators are coupled to each of the knee joints. A power unit, capable of providing power, is coupled to the torque generators. In operation when a leg support is in a stance phase and climbing a slope or stairs, the power unit injects power into the respective torque generator thereby extending the respective knee angle. When a leg support is in stance phase and not climbing a slope or stairs, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to resist flexion of the respective knee joint. When a leg support is in a swing phase, the power unit does not inject any power to the respective torque generator, but without dissipating any stored power in said power unit, it forces the torque generator to minimize its resistance to knee flexion and extension.

Active Ankle Foot Orthosis
ActiveUS20050070834A1Less kinematic differenceIncrease independenceWalking aidsNon-surgical orthopedic devicesWalking cyclePathology diagnosis
An Active Ankle Foot Orthosis (AAFO) is provided where the impedance of an orthotic joint is modulated throughout the walking cycle to treat ankle foot gait pathology, such as drop foot gait. During controlled plantar flexion, a biomimetic torsional spring control is applied where orthotic joint stiffness is actively adjusted to minimize forefoot collisions with the ground. Throughout late stance, joint impedance is minimized so as not to impede powered plantar flexion movements, and during the swing phase, a torsional spring-damper (PD) control lifts the foot to provide toe clearance. To assess the clinical effects of variable-impedance control, kinetic and kinematic gait data were collected on two drop foot participants wearing the AAFO. It has been found that actively adjusting joint impedance reduces the occurrence of slap foot, allows greater powered plantar flexion, and provides for less kinematic difference during swing when compared to normals.

[Problem to be Solved]The problem to be solved by the present invention is to reduce the load applied to the wearer by correcting a parameter in correspondence with detectivity of biosignals.[Means to Solve Problem]The calibration controlling part 162 of the movement assisting apparatus 10 enables the power amplifying part 158 to apply a driving force of the driving source 140 as a load (input torque) from the load generating part 164 to the wearer 12 when the wearer 12 wears the movement assisting wearing device. Then, the wearer 12 applied with the driving force of the driving source 140 generates power from the skeletal muscles by performing a predetermined calibration operation. Accordingly, the physical phenomenon detecting part 142 detects joint angle along with the calibration operation, and the biosignal detecting part 144 detects myoelectric signals. In the parameter correction part 156, a parameter K is corrected based on the difference between the load (input torque) and the driving force (muscular strength) being calculated by the difference deriving part 154 with respect to the phase identified by the phase identifying part 152.

The locking mechanism includes a housing, which supports a plunger for reciprocating movement into and out of engagement with holes on the post. The locking mechanism is affixed to the outside of the tube to bear shearing forces on the plunger. An endcap on the locking mechanism and a topcap on the tube protect the assembly from foreign debris. The locking mechanism may be manipulated remotely using a magnetic switch assembly or manually using a mechanical assembly. A lost motion coupling is integrated into the locking mechanism and / or actuator assembly to enable the remote actuator to be moved or deployed while the latch remains trapped under the influence of a dominant shear load. The lost motion coupling is also effective to allow an operator to deploy the remote actuator at any convenient time prior to a desired change in seat height.
