Alertness sensing spectacles
First Claim
1. A spectacle frame for use in an eye monitoring system which includesa) a nose bridge connecting a pair of ocular framesb) a sensor unit adjustably attached to said nose bridge said sensor unit incorporating a signal emitter and a signal detector recessed into the surface of the unit to reduce the proportion of signal received by said detector which is not from the signal emitter reflected by the eye or eyelidsc) said nose bridge incorporating an adjustment mechanism for adjusting the vertical position of said sensor unit relative to the eyed) a frame arm extending from the outer edge of each ocular frame adapted to fit over the ear of a wearer wherein one of said frame arms incorporates a microprocessor for controlling the sensor unit.

Abstract
Spectacles for use in an eye monitoring system include a pair of ocular frames and a sensor unit adapted to be positioned adjacent an eye of the wearer. A nose bridge connects the ocular frames and incorporates an adjustment mechanism for adjusting the vertical position of the sensor unit relative to the eye. A frame arm extends from the outer edge of each ocular frame and is adapted to fit over the ear of a wearer. The sensor unit incorporates two infra red emitters at different angles and an infra red detector recessed into the surface of the unit to reduce the proportion of signal received by said detector which is not from the signal emitter reflected by the eye or eyelids.

8. A spectacle frame for use in an eye monitoring system which includes
a) a pair of ocular frames at least one of which has a sensor unit adapted to be positioned adjacent an eye of the wearer b) a nose bridge connecting said ocular frames and incorporating an adjustment mechanism for adjusting the vertical position of said sensor unit relative to the eye c) a frame arm extending from the outer edge of each ocular frame adapted to fit over the ear of a wearer said frame arm being pivotally connected to said ocular member by a hinge that is adjustable d) said sensor unit incorporating a light emitter and a light detector recessed into the surface of the unit to reduce the proportion of signal received by said detector which is not from the signal emitter reflected by the eye or eyelids.
