摘要
A strip of flexible material is placed on the forehead or waist of the person involved. The strip has a metal rail to which a connection is provided for printed conductive circuits. On a flexible plate of non-conductive material, is placed a closed glass tube containing internal electrodes which adjoin a raised section where a ball of solid metal or mercury may be moved horizontally and vertically. A buzzer provides a signal or vibration when the ball in the horizontal position rolls to the raised section and closes the current circuit between the electrodes. When the ball moves vertically, the circuit is broken.
