Eye actuated sleep prevention devices and other eye controlled devices
First Claim
1. An eyeglasses attachable device for use by a person including a driver with emitting means for generating beams and with receiving detector means for receiving said emitting means generated beams, where the emitting means are sensing at least one beam across the eye just above the eyeball surface, but below the level of the surface of the eyelid in the direction of the beam receiving detector means, comprising:
- (1) emitting means having a plurality of emitters for generating at least one beam;
(2) slide adjustable mounting means for mounting said emitting means on the temple of said eyeglasses, in such a way, that said beam traverses one of the driver'"'"'s eyes just above the surface of the eye and between the upper and lower eyelids, while the driver'"'"'s eyes are open;
(3) beam widening means, consisting of cylindrical or convex lenses in front of the emitter means and in front of the beam receiving detector means, which make the distance variations between the emitted beam and the eyeball less critical in terms of the operation sensitivity of the device,(4) electronically adjustable selecting means for selecting one of the plurality of emitters on the temple of said eyeglasses, in such a way that the selected beam traverses one of the driver'"'"'s eyes just above the surface of the eye and between the upper and lower eyelids, while the driver'"'"'s eyes are open;
(5) said beam receiving detecting means receiving a full beam when the driver'"'"'s eyes are opened and receiving reduced, scattered beam parts when this driver'"'"'s eyes are closed, for putting out electrical signals, characteristic of the received full beam and scattered beam;
(6) electronic alarm signal generating circuitry for receiving said electrical signals, and detecting input variations and converting said input variations into an alarm signal for alerting the driver, when the driver'"'"'s eyes are closed;
(7) acoustic alarm generator, triggered by said alarm signal, by means of an electrical circuitry, for producing an audible alarm, for waking up the driver;
(8) a power source for powering the beam emitters, the beam receiving detector means, the selecting means, the alarm signal generating circuitry, the electronic circuitry and the acoustic alarm generator.

Abstract
This invention is an eyeglass attachable device for automobile and truck drivers for an alertness alarm signal and for related applications, like controlling the steering wheel movements of a vehicle, a car, a truck or a motorized wheelchair, by means of blinking of the the eyes.
This eyeglass attachable alarm signal device prevents automobile and truck drivers from falling asleep, while driving. A beam of a narrow band infrared light or a beam of ultrasound is used for sensing, whether the driver'"'"'s eyelids are closed or are in an open position. A tiny adjustable infrared light emitter carrier, sliding along one of the eyeglasses temples is used for positioning the light emitter on the eyeglasses temple properly for each driver. This positioning can be done also automatically, by means of using a servomotor or electronically, by selecting and switching on continuously just the right beam, which is passing in close proximity of the eyeball.
