Abstract:
Signal lights are connected to the standard car braking alert circuit and to a first and second additional circuits respectively. A pole balanced on a pivot determines the flashing of different signals by activating switching means to close one or more circuits depending on the magnitude of the braking operation.
Abstract:
A bank of lights (20) mounted across the rear window of a vehicle are progressively illuminated from opposite ends towards the centre, or vice versa, according to the amount of deceleration of the vehicle during braking. Deceleration may be sensed by a group of inertia switches (21-26), for example. An enable signal (32) from the vehicles braking circuit ensures that the lights only operate during braking, and the lights are latched to remain on during any single braking period.

The invention concerns an emergency braking warning device consisting of a printed circuit (1) whereon are implanted, in particular, a voltage regulator/stabiliser assembly (3), a two-way digital inertia sensor (5), a microprocessor (6) and power control elements (10, 11). Said voltage regulator/stabiliser assembly (3) is connected to the vehicle battery and powers the two-way digital inertial sensor (5) and the microprocessor (6). Said microprocessor (6) is adapted to manage data coming from the digital sensor (5) and it is connected to the power control elements (10, 11) interposed on the circuits of the right (8) and left (9) flashers, to enable the triggering of said flashers (8, 9) when the programmed braking threshold is exceeded.

A device (100) for indicating a change in the state of motion comprises at least one light emitting element (106) implemented with LED technology, as well as an acceleration sensor (101 ) adapted to determine acceleration with respect to 1 -3 axes. In addition, the device comprises a control means (102) adapted on the basis of data produced by the acceleration sensor to control said light emitting element in such a way that, when the acceleration sensor's acceleration is negative, i.e. for example in braking, the intensity of emitted light is adapted to strengthen.
