First Claim
1. A security system for detecting the presence of one or more persons in a location to be monitored, said system comprising:
- (i) one or more light sources directed in the direction of said location;
(ii) one or more light detectors for detecting reflections of said one or more light sources from said one or more persons to form an image representing eyes of said one or more persons;
(iii) a scanning module to direct said one or more light sources and said one or more light detectors at narrow portions of said location at a time;
(iv) a scanning controller for driving said scanning module; and
(v) a processing unit for analyzing the images received on said one or more light detectors to form an image representing eyes in said location and to identify and count the number of eyes on said image.

Abstract
A security system and method for detecting the presence of one or more persons in a location, by: directing a light source in the direction of the location; detecting reflections of the light source from the location by a light detector in order to form an image representing the one or more persons'"'"' eyes; and analyzing the image received on the light detector to identify and count the number of eyes on the image. Preferably, the analyzed information is then communicated to a remote facility for further processing. Appropriate action to take based on the analyzed information includes issuing an alert, turning on an alarm system, sending a message to one or more predetermined persons and/or machines.

17. A secured mobile phone, for alerting the user of said mobile phone if said user falls asleep, said mobile phone comprising:
-
(i) a light sources directed in the direction of said user; (ii) a light detectors for detecting reflections of said light source from said user to form images representing the eyes of said user; and (iii) a processing unit for analyzing the image received on said light detector to identify if said eyes are open, and issue an alert if the eyes are determined to be closed for more than a predetermined amount of time.
