Abstract: An apparatus for wireless communications between communication modules, the apparatus including a main transmission line which has a plurality of coupling points, wherein the apparatus comprises a plurality of main antennas, and wherein each main antenna is linked to a coupling area for a directional coupling between the main antenna and the main transmission line at a coupling point and each main antenna is adapted to communicate with an auxiliary antenna linked to a communication module.

Abstract: A system for controlling supply of a device. The device can be a power retention device that requires to be permanently powered. To this end, it can be alternatively powered by a power supply, in a first mode, or by a battery, in a second mode. At least one sensor of the system acquires data related to the battery, such as environmental data, the voltage of the battery or the discharge current of the battery. Based on the data and at least one characteristic curve of the battery, a battery monitoring module is configured to switch between the first and second modes to improve the lifetime of the battery.

Abstract: A backup power supply system for managing data backup operation of an electronic device, comprising: a DC/DC converter having a main power input and a power output; a boost converter having a power input and a power output; a thermoelectric generator associated with a chip and electrically connected to the power input of the boost converter, wherein the thermoelectric generator is able to heat or cool the chip; a microcontroller electrically connected to the power outputs of the first and the second power converter, and electrically connected to a set of components able to perform data backup operation of the electronic device, wherein the microcontroller is configured to determine an electrical energy required to perform data backup operation by the set of components, wherein the microcontroller is configured to compute from the determined electrical energy a temperature deviation to reach by the thermoelectric generator, wherein the temperature deviation is the difference between the temperature inside the

Abstract: The invention relates to a system for controlling supply of a device (104). The device can be a power retention device that requires to be permanently powered. To this end, it can be alternatively powered by a power supply (140), in a first mode, or by a battery (102), in a second mode. At least one sensor (110-114; 105) of the system acquires data related to the battery, such as environmental data, the voltage of the battery or the discharge current of the battery. Based on the data and at least one characteristic curve of the battery, a battery monitoring module is configured to switch between the first and second modes to improve the lifetime of the battery.
