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.
