1. System for detecting a mobile or immobile entity in a defined space, comprising:
- a presence detector for detecting a presence of said entity in at least two partially overlapping observation areas of said space, said presence detector collecting at least one piece of immobile presence information of this entity, irrespective of a movement thereof, and at least one piece of movement information of said entity in each of said observation areas, wherein the at least one piece of immobile presence information is a logical variable indicating a presence or absence of the entity, and wherein the at least one piece of movement information is a logical variable indicating a movement or absence of movement of the entity;
a processor, for merging by logic operations the at least one piece of immobile presence information and the at least one piece of movement information of each entity collected for each of said observation areas, and generating a logic signal as result of the merging; and
a decision maker, which is connected to the processor for controlling an action in accordance with the logic signal.

Abstract
System (10) for detecting the position of a mobile or immobile entity (20) in a defined space (30), characterized in that it includes:
- means (40) of detecting the presence of said entity in at least two partially overlapping observation areas (Z1, Z2) of said space, said means being adapted for collecting at least one piece of immobile presence information (Ip) and one piece of movement information (Im) of said entity in each of said observation areas,
- processing means (50) which are adapted for carrying out logic operations on at least a portion of said information collected for each of said observation areas,
- decision means (60), which are connected to the processing means and adapted for controlling an action on the basis of a logic signal generated by the processing means.

12. Method of detecting a mobile or immobile entity in a defined space, the method comprising:
-
detecting a presence of said entity in at least two partially overlapping observation areas of said space, so as to collect at least one piece of immobile presence information of said entity, irrespective of a movement thereof, and at least one piece of movement information of said entity in each of said observation areas, wherein the at least one piece of immobile presence information is a logical variable indicating a presence or absence of the entity, and wherein the at least one piece of movement information is a logical variable indicating a movement or absence of movement of the entity; merging, by logic operations, the at least one piece of immobile presence and movement information of said entity collected for each of said observation areas, so as to generate a logic signal; analysing said logic signal so as to control an action in accordance with said logic signal. - View Dependent Claims (13, 14, 15, 16)
