Abstract: A system for controlling electrical power supply of an aircraft includes at least two control boards and at least two switching members. Each switching member is connected to each control board. Each control board includes a processor. Each processor is configured to determine a command for switching states of switch contacts of each switching member and to determine information relating to validity of each switching command. Each switching member includes a transmitter to determine a command to be transmitted to a detector to detect parallelization, a power actuator configured to transmit a power signal to the switch contacts depending on the command received from the detector, and switch contacts configured to selectively open or close an electrical power supply line. The command is selected from the switching commands and the information relating to the validity of each switching command.

Abstract: A communication architecture, for exchanging data between processing units that are intended to operate in parallel comprises a communication system comprising a set of interfaces each intended to be linked to a processing unit, a set of sequencers that are able to define, for each processing unit, time intervals of access to a shared memory accessible by the processing units for writing and reading data, for the sequential arbitration of accesses to said memory, and a set of address managers able to allocate each processing unit ports for access to the shared memory.

Abstract: This electromagnetic contactor comprises a set of controlled switches (C1, C2, C3), at least one electromagnetic field generator (L; L1, L2), for example a coil, associated with an adjustable core (P) controlling the state of the controlled switches and a unit (UC) controlling the power supply of the electromagnetic field generator. It comprises means for detecting the position of the adjustable core to detect the state of the controlled switches.

Abstract: A method of distributing electric current to electrical outlets, and a program to implement same, including the steps of supplying electric current to the electrical outlets not yet connected to an electronic device upon receipt of a distribution request from the electrical outlets; determining the instantaneous current intensity supplied to the electrical outlets; comparing the determined current intensity to a threshold referred to as the maximum threshold; and when the predetermined current intensity is greater than the maximum threshold, selecting an electrical outlet and terminating the supply of electric current to the selected electrical outlet. The steps of selection and termination being carried out while continuing the step of supplying electric current to the electrical outlets not yet connected to an electronic device upon receipt of a distribution request from the electrical outlets.

Abstract: A microcontroller integrated circuit comprises a processor core which exchanges data with at least one data processing and/or storage device. The integrated circuit comprises a mask-programmed read only memory containing a generic program such as a test program which can be executed by the microcontroller. The generic program includes a basic function for writing data into the data processing and/or storage device or devices. The write function is used to load a downloading program. Because a downloading program is not permanently stored in the read only memory, the microcontroller can be tested independently of the application program, and remains standard with regard to the type of memory component with which it can be used in a system.
