Abstract
Abstract An urgent braking device is described which connects in series with a brake light system of a vehicle. The device incorporates power modulating means connected in parallel with an inertial switch. The device is attached to the vehicle with the inertial switch in an orientation relative to the vehicle whereby the switch is normally-closed. The switch opens when the vehicle is decelerating in excess of a predetermined rate. Upon opening, the switch interrupts power supplied to the brake light system and a power modulating means is activated, resulting in a modulated power signal supplied to the brake light system and thereby causing the brake lights to flash.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
129 words
A flasher device for use with a brake light system of a vehicle, comprising: a source of power; a brake switch; a brake light; a resistor; modulating means for modulating power; a normally-closed mercury switch connected in parallel with said modulating means and said resistor, said mercury switch being fixedly oriented relative to said vehicle so that said normally-closed switch opens in direct response to a predetermined rate of deceleration of said vehicle; a casing containing said mercury switch and said resistor, said casing having socket means for removably connecting said modulating means in parallel with said mercury switch; and means for connecting in series said source of power, said brake switch, said brake light, and the parallel connection of said modulating means, said resistor and said mercury switch.
Claim 2
Dependent Claim
129 words
A flasher device for use with a brake light system of a vehicle, comprising: a source of power; a brake switch; a brake light; a resistor; modulating means for modulating power; a normally-closed mercury switch connected in parallel with said modulating means and said resistor, said mercury switch being fixedly oriented relative to said vehicle so that said normally-closed switch opens in direct response to a predetermined rate of deceleration of said vehicle; a casing containing said mercury switch and said resistor, said casing having socket means for removably connecting said modulating means in parallel with said mercury switch; and means for connecting in series said source of power, said brake switch, said brake light, and the parallel connection of said modulating means, said resistor and said mercury switch.
Claim 3
Dependent Claim
41 words
The device of claim 1 wherein said casing has means for attaching said casing to said vehicle with said switch in an orientation relative to said vehicle so that said switch opens in direct response to said predetermined rate of deceleration.
Claim 4
Dependent Claim
25 words
The device of claim 2 wherein said means for attaching is an adhesive means, whereby the casing of said device is adhered to said vehicle.
Claim 5
Dependent Claim
30 words
The device of claim 2 wherein said means for attaching includes means for articulating said device, whereby said device is adjustable to a plurality of orientations relative to said vehicle.
Claim 6
Dependent Claim
16 words
The device of claim 1 wherein said means for modulating power is a bimetallic flasher unit.
