    摘要： The present invention provides a method of drilling a hole in a workpiece in order to control breakthrough of the workpiece comprising the steps of : a) initiating contact between a drill bit of a drill unit and the workpiece; b) operating the drill unit to rotate the drill bit to drill the workpiece; c) during drilling of the workpiece measuring the force, F and torque, T , experienced by the drill bit; d) calculating a variable F', based on the measured force, F , representing the rate of change of F ; e) calculating a variable, T' based on the measured torque, T , representing the rate of change of T ; f ) calculating a variable F' ' representing the rate of change of F '; g) calculating a variable T ' ' representing the rate of change of T "; h) detecting the onset of breakout of the workpiece by use of the variables F ', F ' ', T ' and T ' '; i) thereby controlling the speed of rotation of the drill bit during breakthrough of the workpiece to control the degree of breakout of the drill bit from the workpiece. A drilling system is also disclosed.

    摘要： This invention relates to control means and actuators (1) with feed-back sensors (5) suitable for use in tele-operated systems, especially surgical tools and endoscopes. A membrane (9) is provided to flex with an operator's finger, and a sensor (20) responsive to longitudinal flexing of the membrane produces an output signal dependent on the position of the finger. The membrane (9) covers the finger like a glove, and extends across the back of the hand. The sensor (20) preferably comprises an optic fibre (13). The actuator (1) is fluid-operated and comprises a corrugated tube (7) with a length-restraining member (8) along one side so that the tube curves when it is extended by internal fluid pressure. A feedback sensor (5) is responsive to the position of the tube (7) and/or lateral force experienced by the tube (7) when it engages an external object. A feedback signal from the sensor (5) operates a feedback force generator (3) in contact with the operator's finger.
