A method for reprogramming bidirectional objects is disclosed. The objects contain a common key, at least two objects being paired to allow the sending of a command from one object of the pair to the other object of the pair and the execution of the command by the other object. The method includes the steps of 1) providing the objects with a new common key; 2) then when a command is sent from one object to another object with which it is paired, verifying that the two objects contain the new common key, and 3) refusal by the other object to execute the command if the two objects do not contain the new common key.

Method for reprogramming bidirectional objects

The inventive method makes it possible to communicate in a network comprising wireless nodes provided with communications means enabling to communicate through a wireless channel and wire nodes provided with communication means enabling to communicate through a wire channel. Said method is characterised in that the wire node repeats a message received exclusively through a wireless channel if a signal acknowledging the message reception is not received, wherein the transmission of said acknowledgement signal is generated in a first time slot upon the reception of the signal though a wire channel.

A method of testing and installing a remote control unit (RCU) for controlling elements (ACT, ACT, ACT) of a home automation network, intended for managing the security or heat or light comfort in a building, comprising the use of software (ALS) emulating the remote control unit in a computer (PCU) to define a virtual remote control unit (VRCU), and the configuring of the virtual remote control unit to enable the elements of the network to be controlled, wherein sending rights are assigned to the virtual remote control unit at the time of that configuration and wherein the cancellation of these sending rights results at least from a step for copying the configuration (CFG) of the virtual remote control unit in the remote control unit.

Method of testing and installing a home automation remote control unit

Secure transfer of information between a first command transmitter and a second command transmitter such as those employed for remote control of actuators employed in home automation systems for example for opening and closing windows, solar protection, ventilation, roller blinds, garage doors and the like, is achieved by first authenticating the first command transmitter with respect to a third object preferably constituting part of the existing network, such as a command receiver or command transmitter and only transferring information to the second command transmitter when authentication of the first command transmitter has succeeded. The method particularly applies when a new second command transmitter is to be installed on a home automation network, having identical rights and functionalities to those of the existing first command transmitter.

Method for transmitting information between bidirectional objects

The method applies to objects comprising a memory in which there is a mathematical mapping and at least one key. It is a method which comprises the following steps:

The method makes it possible to control and monitor the dynamic operation operation of an actuator intended to drive a movable element of a building protection installation. The actuator is associated with nearby controlling means comprising a power supply device or converter, a local processing unit, and a two-way radiofrequency transmitter, constituting a local actuation unit. The method is characterized in that it consists in transferring to another unit, called the remote processing unit, all or part of the processing for analyzing measurements relating to said actuator and/or to said movable element.

Method for controlling the speed of a single-phase asynchronous induction motor, the stator of which is equipped with a main winding (BP) and an auxiliary winding which consist of half-windings (B1, B2) which are magnetically coupled and wound in opposite directions, in which method the main winding is powered directly using an AC source and the auxiliary winding is powered using a current delivered by a full-wave rectifier and using two switching devices (T1, T2), so as to generate in the auxiliary winding a current which is phase-shifted by 90.degree.. The method consists in varying the motor torque by altering the time that at least one of the switches spends closed/open.
