Eyelash activated drowsy alarm

DETAILED DESCRIPTION Referring to FIG.
1.
, the eyeglass frame's ear-piece 1 includes a back of the ear hook 2 to hold the glasses in a stable position, and the ear-piece also supports the electronics module 3 within which an miniaturized electronics assembly 4 is activated by an on/off switch 5 supplied by a rechargeable battery 6.
An electrical plug-in cord 7 from a cigarette lighter socket, or other source, supplies power when recharging is required and during times when the battery is depleted.
Alarm of drowsiness is provided to the driver by an audible sound from a speaker 8.
A vibrator could be provided for the deaf, for those who enjoy loud radio music, or are loudly conversing.
The electronics module 3 is located toward the center of the ear-piece 1 and therefore not in the way of peripheral vision as was the enclosure for the wave emitter, reflex cell and photo-detector in the Anbergen patent.
The device is independent of the type of lens 9 used in the glasses.
The lens frame 10 supports an infrared emitter module assembly 11 by means of a bendable support attachment member 12 which provides both fore and aft linear and also angular adjustment of the beam 13.
The beam is focused to a point 14 which is approximately at the center of the eyelash when the eye is closed.
If not interrupted by the eyelash, the beam continues on to impinge on the detector module assembly 15 supported by attachment member 16 from the eyeglass frame 10.
FIG.
2.
is a top view showing the position of the light beam being intersected by the eyelash when the right eye is closed.
The angled position of the beam allows the detector module assembly 15 to be mounted close to the glasses' frame at the nose for easier fit.
Emitter module assembly 11 consists of a light-beam source such as an infrared light emitting diode 17 mounted in an enclosure 18 along with a lens 19 and an anti-reflecting light absorbing member 20.
The lens is placed such as to produce a focused beam at point 14 which is close to the centerline of the eye and the most dense part of the eyelash
