Abstract: Methods and apparatuses for generating information for navigation in an environment are disclosed. The method comprises generating, by a device, state information about a part of the environment where the device is positioned, receiving, by the device from at least one other device, messages comprising state information about a part of the environment where the at least one other device is positioned, the meaning of the messages being learned based on emergent communication, abstracting the state space for the environment by an abstractor module based on the generated state information and the received state information messages to provide an abstracted state space, and generating information for the device by a reinforced learning module for navigation in the environment based on the abstracted state space and further state information generated by the device and received from the at least one other device.

Abstract: A multi-area passive infrared sensor (PIF) produces a two-dimensional image formed of a grid of squares corresponding to adjacent elementary areas of an area to be monitored, with, for each square, a respective heat signal. The squares of the grid are classified into authorized and secured squares, and the device produces, for each square, an indicator of presence/absence of a target. In the presence of a detected target in at least one square, the processor conditionally delivers an alert as a function of i) the position on the grid of the detected target and ii) of the classification into authorized or secured square of the square in which this target is detected. A data memory stores a history of the states of the grid, and the processor performs a tracking of the target by an algorithm based on adjacent squares, based on this history.
