ABSTRACT:
A head movement sensor, which may be used for such things as golf practice, is adapted to be attached or carried on a person's head. The device consists of a sensor which is mounted to the head and senses an initial position by means of a hollow tube carrying a conductive liquid with electrodes extending within the tube. The tube is shaped so that as the head is angularly displaced from the initial position to a displaced position, the liquid flows within the tube, changing the resistance between the electrodes. By measuring the change in resistance, an electrical signal can be derived. Sudden changes in angular displacement also produce an electrical signal. The electrical signals are processed to produce an audible indication.
