By placing the tether structures on or over adjacent spinous processes, flexion of a spinal segment can be controlled in order to reduce pain.

The invention relates to embodiments of methods for extending a subject-controllable range of joint motion, and for increasing subject control of joint movement within a range of motion. Embodiments include fastening a powered device around a joint so as to be able to control the joint, allowing the subject to move the joint within a range of volitional motion, and then engaging the powered device to support movement of the joint into an expanded, rehabilitative range. In some embodiments, the device supports joint movement by substantially providing the force to move the joint beyond the volitional boundary. In other embodiments, supporting movement includes the subject substantially providing the force, and the device allowing movement only in a desired direction. The invention further relates to a system for increasing the functional capability of a joint by implementing embodiments of the method. By such methods and system, rehabilitation is accomplished both by building strength, and training neural pathways.

A robot system includes a robot and a robot controller including a drive unit, a memory that stores an arm-occupied region and a movement-forbidden region, a target position calculation unit that outputs a target position of a tool or a workpiece, a movement-forbidden region entry monitoring unit that checks whether the arm-occupied region based on the target position enters the movement-forbidden region and outputs a stop request if it is checked that the arm-occupied region enters the movement-forbidden region, and a predicted-coasting-position calculating unit that calculates a predicted coasting position of each axis and a coasting position of the tool or the workpiece in the case that the robot is urgently stopped. The movement-forbidden region entry monitoring unit checks whether the arm-occupied region at the coasting position enters the movement-forbidden region and outputs another stop request if it is checked that the arm-occupied region enters the movement-forbidden region.

A pivoting arrangement for a shaving device, comprising a pivoting member (10), adapted to support a shaving head, a cradle (11), pivotly supporting the pivoting member, and a spring loading arrangement (13) arranged to bias the pivoting member in a resting position. The spring loading arrangement has a limited active range, so that, when the pivoting member is brought out of the resting position in a first pivoting direction, the spring loading arrangement is prevented from interacting with the pivoting member in a first point of action (14a), and when the pivoting member is brought out of the resting position in a second pivoting direction, the spring loading arrangement is prevented from interacting with the pivoting member in a second point of action (14b). As a result, the resting position will not be dependent on e.g. the spring constants of different springs in the spring loading arrangement. The resting position will thus be more exactly defined, and exhibit less variation than conventional solutions. Also, the total force acting on the pivoting member will be reduced, thus causing less friction, also serving to improve the predictability of the arrangement.

A frame for automatic umbrella style canopy tents and a tent including the frame are disclosed. In the tent frame, the spreaders, which expand or collapse the upper ribs in radial directions, are configured as extendible members, thus reliably locking the tent frame in an expanded state and securely maintaining a pitched state of the tent.

When force is applied to the press operation column, then the press operation column exerts force on the clamping column, and causes the clamping column to separate from the weight. Accordingly, a user is able to quickly change weights on the dumbbell.

A pivoting arrangement for a shaving device, comprising a pivoting member (10), adapted to support a shaving head, a cradle (11), pivotally supporting the pivoting member, and a spring loading arrangement (13) arranged to bias the pivoting member in a resting position. The spring loading arrangement has a limited active range, so that, when the pivoting member is brought out of the resting position in a first pivoting direction, the spring loading arrangement is prevented from interacting with the pivoting member in a first point of action (14a), and when the pivoting member is brought out of the resting position in a second pivoting direction, the spring loading arrangement is prevented from interacting with the pivoting member in a second point of action (14b). As a result, the resting position will not be dependent on e.g. the spring constants of different springs in the spring loading arrangement. The resting position will thus be more exactly defined, and exhibit less variation than conventional solutions. Also, the total force acting on the pivoting member will be reduced, thus causing less friction, also serving to improve the predictability of the arrangement.
