1. An electronic management system, comprising:
- means for emitting infrared light;
means combined with said emitting means for sensing infrared light reflected from an object within a range of view of a certain zone of detection;
means for comparing pulses triggered by said sensing means to a reference value;
means connected with said comparing means for timing each of said pulses triggered to provide error free delayed clock-like pulses;
means for mounting said emitting means next to said sensing means to provide same side detection with said range of view of said certain zone;
means connected with said timing means for controlling an electronic means such as a light means, an audio device, a video device, and the like, said control means including means for counting in one of a positive value and a negative value in relation to a reference value when triggered by one of said delayed pulses;
means for mounting said controlling means whereby said controlling means is connected to said electronic means; and
means for manually operating said counting means.

Abstract
An infrared sensitive system which maintains an inventory of the number of occupants within a monitored room for controlling certain electronic equipment in response to the presence of occupants within the monitored room. The monitoring system activates the electronic equipment when it senses a person entering the unoccupied room, and it deactivates the electronic equipment when the last person exits the room. Switch members provide for manually resetting and overriding the control portion of the system.

27. An electronic management system, comprising:
-
means for monitoring a certain zone or range of view for ingress and egress of occupants through said zone or range of view whereby said monitor means comprises a unit member having a first monitor set and a second monitor set, each of said first monitor set and said second monitor set including means for emitting infrared light combined with means for sensing infrared light reflected from an object within said certain zone; means connected to said monitor means for maintaining an inventory of said occupants within said zone, whereby said inventory means comprises means for comparing pulses triggered by said sensing means to a reference value, said comparing means including means for filtering ambient noise, means for filtering ambient light, means for amplifying said pulse, and means for timing said pulse whereby a clock-like signal is established; means for mounting said monitor means and said inventory means comprising a common housing unit whereby said emitted light originates from and said infrared light reflection is received in said common housing unit mounted in a predetermined location substantially central within said certain zone or range of view; and means for comparing pulses triggered by said sensing means to a reference value, said comparing means including;
means for filtering ambient noise, means for filtering ambient light, means for amplifying said pulse, and means for timing said pulse whereby a clock-like signal is established. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35)

36. An improved infrared monitoring system wherein a device is activated by infrared light reflected from an object within a certain range of view to activate a control member connected to an electronic device whereby said electronic device is activated, wherein the improvement comprises:
-
an infrared sensitive monitoring unit means for relaying a pulse in reaction to infrared light reflected from an object, said unit means comprising a first monitor set and a second monitor set; means for mounting said unit means in a certain zone whereby one of said first monitor set and said second monitor set has one of a first range of view and a second range of view of said certain zone and the other of said first monitor set and said second monitor set has the other of said first range of view and said second range of view of said certain zone, and one edge of one of said first range of view and said second range of view abuts one edge of the other of said first range of view and said second range of view; means connected to said unit means for translating said relayed pulses into one of a positive value and a negative value, said translating means comprising; clock means for establishing a reference period of time to respond to each of said relayed pulses, means for counting comprising a first counting member and a second counting member, whereby one of said first counting member and said second counting member counts in one of a positive mode and a negative mode and the other of said first counting member and said second counting member counts in the other of said positive mode and said negative mode, means for combining said positive values and said negative values, said combining means having a reference value, and means for connecting said translating means to said electronic means whereby when said combined value has one of said reference value and a value other than said reference value, said electronic means is one of activated and deactivated, and when said combined value has the other of said reference value and other than said reference value, said electronic means is the other of activated and deactivated; and means for connecting one of said first monitor set and said second monitor set to one of said clock means and one of said first counting member and said second counting member, and for connecting the other of said first monitor set and said second monitor set to the other of said clock means and said one of said first counting member and said second counting member.
