1. A sleep-preventing alarm operable in conjunction with a motor vehicle for providing a periodic visual and audible alert to thereby preclude a driver of a motor vehicle from falling asleep comprising, in combination:

  • a hollow rigid housing having a top wall, a bottom wall, and a periphery interconnecting the top wall with the bottom wall formed of an upstanding oval front face, an upstanding oval rear face, and a pair of opposed and curved side walls;

    a rigid mounting bracket having a planar central portion removably coupled to the housing and two L-shaped feet extended downwards therefrom, each foot further having a pair of mounting holes formed thereon and with each mounting hole adapted to receive a bolt for coupling the mounting bracket to a vehicle, each foot additionally having a layer of adhesive applied thereto between the mounting holes and covered with a peel-off paper backing and with the backing removed for adhering the feet to a surface of a vehicle;

    timer circuitry disposed within the housing for transmitting a periodic indicator signal upon completion one of a 30-second interval in a first mode of operation, a 60-second time interval in a second mode of operation, a 90-second interval in a third mode of operation, a 120-second interval in a fourth mode of operation, a 150-second interval in a fifth mode of operation, and a 180-second interval in a sixth mode of operation;

    a lamp extended through the front face of the housing for transmitting a visual alert upon receipt of a lamp indication signal;

    a speaker extended from the top wall of the housing for transmitting an audible alert upon receipt of a speaker activation signal;

    indicator circuitry coupled to the timer circuitry, the speaker, and the lamp and with the indicator circuitry generating both a periodic lamp indication signal for a pre-determined amount of time and a periodic speaker activation signal with a characteristic strength and frequency for a pre-determined amount of time upon receipt of the indicator signal from the timer circuitry, the indicator circuitry further including a head-phone jack coupled thereto and with the head-phone jack couplable with an external head-phone set;

    keypad circuitry extended from the housing and coupled to the timer circuitry and indicator circuitry, the keypad circuitry including a first, a second, a third, a fourth, a fifth, and a sixth back-lit momentary pushbutton switch and with the pushbutton switches arranged in a horizontal sequential fashion to define a timing bar, the first pushbutton depressible for placing the timing circuitry in a first mode of operation, the second pushbutton depressible for placing the timing circuitry in a second mode of operation, the third pushbutton depressible for placing the timing circuitry in a third mode of operation, the fourth pushbutton depressible for placing the timing circuitry in a fourth mode of operation, the fifth pushbutton depressible for placing the timing circuitry in a fifth mode of operation, and the sixth pushbutton depressible for placing the timing circuitry in a sixth mode of operation, the keypad circuitry further including a volume control dial and a tone control dial extended from the front face of the housing with the volume control dial rotatable for adjusting the strength of the speaker activation signal and thereby controlling the volume of the audible alert transmitted from the speaker and with the tone control dial rotatable for adjusting the frequency of the speaker activation signal and thereby controlling the pitch of the audible alert signal transmitted from the speaker;

    a rotatable spring-loaded spool secured within the housing and including an actuateable spool switch engaged therewith and with the spool manually rotatable in one direction when a torquing force is applied thereto and automatically rotatable in an opposite direction upon activation of the switch; and

    a power cable having a proximal terminal end coupled to the timer circuitry, indicator circuitry, and keypad circuitry and a distal plug end couplable with a lighter socket of a vehicle for receiving electrical energy therefrom for circuitry operation, the power cable positioned in a wrapped configuration around the spool and selectively manually payable therefrom and automatically retractable thereon.
