Warning device for alerting a person falling asleep
First Claim
1. A warning system for warning a user that a condition being one of the user having fallen asleep and the user being about to fall asleep exists, the user having at least one eye and a pair of eyelids, the eyelids varying in state from wide open to completely closed, the eyelids completely covering the eye when in the completely closed state, said warning system comprising:
- an ophthalmic contact device adapted for application to the user'"'"'s eye, said ophthalmic having a detectable feature which produces a signal in response to incident energy, said signal varying in response to the state of the user'"'"'s eye;
a detector capable of transducing said signal into a detector output signal;
an alarm means capable of generating a stimulus that can awaken a person; and
a data processing and control circuit means communicating with both said detector and said alarm means, said data processing and control circuit means being programmable, said data processing and control circuit means being programmed with criteria establishing an alarm condition corresponding with a probable condition that is one of the user having fallen asleep and the user being about to fall asleep, said data processing and control circuit means processing said detector output signal to determine if said alarm condition exists, said data processing and control circuit means controlling said alarm means to generate said stimulus if said alarm condition exists.

Abstract
A warning system for warning a user that they have fallen or are about to fall asleep is disclosed. The system includes a contact lens having a detectable feature such as a holographic marking or other markings or indicia, metallic substances, color, or some microcircuit device, which will be worn by the user. The system also includes a detector or sensing device that can detect the presence of the contact lens when the eyelids of the person wearing the contact lens are open. The type of detector will vary depending upon the type of detectable feature incorporated into the contact lens. When the eyelids of the user become heavy or close, so as to cover a substantial portion of the detectable feature of the contact lens for a predetermined period and/or at a predetermined frequency, then the detector will generate a signal to thereby awaken the user.
