Abstract:
1. A medical device, comprising: a movable component; a control unit that controls a movement of the movable component; a plurality of sensors arranged on the movable component wherein each sensor: wherein a voltage is supplied to the each sensor without a cable, wherein the voltage is supplied to the each sensor by a battery, wherein the battery is charged by a dynamo, wherein the dynamo is only arranged on the movable component, wherein the each sensor wirelessly sends the signal to the control unit by acting on changes of the voltage applied on the each sensor when the collision occurs via a rubber switch, wherein the rubber switch comprises two metal elements that are embedded in a rubber material and are pushed against each other when the collision occurs that changes a resistance achieved by the two metal elements and the voltage applied on the each sensor, and wherein the plurality of sensors are connected in a daisy chain arrangement.
