Abstract: A method is for controlling a home automation installation. The installation includes pieces of home automation equipment and a central control member. The method includes providing a desired operation of the installation, providing a first operation of each piece of equipment, optimizing the operation of the installation by modifying the first operation of at least one piece of equipment, to obtain a second operation of the at least one piece of equipment, and an operation of the installation according to the desired operation, and installing a virtual machine in the at least one piece of equipment. The virtual machine is able to impose the second operation on the at least one piece of equipment.

Abstract: A support for computer data back-up units is designed to receive at least two distinct sizes of back-up units. The support has a bottom and at least one stationary wall perpendicular to the bottom. The support also has an additional wall extending perpendicularly to the bottom of the support and parallel to the stationary wall. The additional wall is mounted to be movable relative to the bottom of the support between at least two receiving slots respectively associated with the distinct sizes of the back-up units.

Abstract: The present invention relates to a connection system for connecting computer data backup units to a computer motherboard comprising: a support for different sizes of computer data backup units, wherein the backup units carry a connector, or carry a superposition of a plurality of connectors, a multi-stage connector configured to be connected to the motherboard and the backup unit connectors, wherein the multi-stage connector comprises at least two connection stages superposed and fixed to one another. According to the invention, the at least two superposed connection stages of the multi-stage connector are offset relative to one another according to the sense of the connection to the connectors of the computer data backup units carried by the support.

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.
