Steering alert system
First Claim
1. A steering alert system for providing an alarm when a vehicle driver may have fallen asleep or lost attention comprising, in combination:
- a vehicle having four wheels and a steering wheel with a steering column coupled therebetween, the steering column being cylindrical with a central axis of rotation and an exterior cylidnrical surface;
a plurality of linear marks upon the exterior cylindrical surface of the steering column, the marks being parallel with respect to each other and parallel with the axis of the steering column;
a photo-electric sensor fixedly positioned adjacent to the marks to sense the presence and absence of marks thereadjacent as caused by the rotational movement of the steering column resulting from the rotation of the steering wheel by a driver;
audio and visual alarms adapted to be energized for alerting a driver and passenger, if present, when the sensor does not sense movement of the marks and steering column and steering wheel within a predetermined lapsed time;
electronic timers including delay switches to preclude energizing the alarms if the sensor senses the movement of the steering column and marks in greater than the predetermined lapsed timean adjuster under the control of the driver to change the extent of the predetermined lapsed time in which the sensor will energize the alarm; and
an on/off switch under the control of the driver to selectively activate and inactivate the system.

Abstract
An alert system for providing an alarm is disclosed. The system includes a vehicle having a steering wheel with a steering column, the steering column having an exterior surface. Marks are provided on the exterior surface of the steering column. A sensor is positioned adjacent to the marks to sense the presence and absence of marks thereadjacent as caused by the rotational movement of the steering column. At least one alarm is adapted to be energized for alerting a driver and passenger, if present, when the sensor does not sense movement of the marks and steering column and steering wheel. Electronic timers including delay switches are provided to preclude energizing the alarms if the sensor senses the movement of the steering column and marks in greater than the predetermined lapsed time.
