Abstract: A movable storage system includes at least two movable storage units, a brush-less motor accommodated in each of the units for moving the units in movement directions, each of the motors comprising a plurality of stators and a rotor, and each of the motors including a sensor. Each sensor detects an angular position and a rotational speed of a respective rotor of each motor using the magnetic poles of the rotor. Each sensor outputs an angular position signal representing the angular position and a rotational speed signal representing the rotational speed of the rotor. A motor control is associated and in communication with each motor and sensor, which is operable for controlling the motor. The controls are adapted to receive the position and speed signals of each sensor with each control having a signal-outputting terminal to provide a command signal output to its respective motor.

Abstract: A suture anchor that allows a surgeon to securely and efficiently suture soft tissue to bone without knotting the suture, comprising a locking body through which a suture is passed, and an anchor collar, which, when positioned over the suture passing through the locking body, secures the suture.
