Abstract

This patent describes a new electronic automatic system conceived to detect a relative motion of two different objects, using a magnetic generator which produces an AC electric tension with its basic components respectively on the shaft and on the body, this movement allowing to obtain an electric tension capable to light one or more light emitting diodes on a control panel or on a safety device. This patent also refers to a new safety signaling device developed for bicycles and all kind of vehicles that don't have another electric source. The new system has an electric circuit (1) composed by a tubular coil (2) with ferromagnetic core (3), the terminals (4) of the spires being connected to the terminals of one or more leds (5), the coil (2) being attached to a moving part (6) of a machine, on a position which allows the coil (2) to cross the magnetic field of the North or South pole of a magnet (7) fastened to another part (8) of the same machine, in order the coil (2) and the magnet (7) can describe a relative motion. The magnet (7) can be put on a disc (10) fastened to a shaft (11) of a vehicule, while the coils (2) can be attached to a fixed plate (12), the spires being connecteds to leds (5) positioned on a pannel or display.
