Patent ID: 7342487

Claim:
A device for automatically actuating an emergency indicator with actuation of a turn signal and depressing the foot brake comprising: (a) at least one emergency indicator; (b) a first unit comprising means for providing a first signal consisting of a continuous wave signal; (c) a second unit comprising means for providing a second signal consisting of a pulsating square signal; and in combination with, (d) a control unit ( 1 ) comprising: (i) means for inputting the first signal to the control unit; (ii) means for inputting the second signal to the control unit; and (iii) means for automatically actuating the emergency indicator with simultaneously active said first and second signals, and absent actuation of at least one of wipers and fog lights; said control unit comprises means for receiving a continuous voltage from the automobile vehicle, said control unit comprising three inputs ( 3 , 6 , 5 ) ( 3 to 5 ) and a plurality of outputs ( 6 to 15 ), said inputs ( 3 to 5 ) having means for receiving continuous and pulsating square wave signals, for actuating the control unit ( 1 ) to automatically actuate said emergency indicator, further characterized in that two inputs ( 3 , 4 ) receive continuous level signals, whereas the other input ( 5 ) receives a pulsating, square wave signal, these input signals being generated independently of said control unit ( 1 ), such that the response of the unit through said outputs ( 6 to 15 ) occurs when only one continuous signal is fed through the corresponding said two inputs ( 3 , 4 ), simultaneously with the pulsating signal through the respective said other input ( 5 ), further comprising means for operably connecting the vehicle turn signals to said second unit, and means for operably connecting the front brake to said first signal; whereby when the control unit ( 1 ) detects the one continuous signal and the input ( 5 ) receives said pulsating square wave signal, and wherein with both said signals the energizing indicator is automatically actuated with actuation of the turn signal and depression of the foot brake only.
