A wireless local network and method integrating the locating and the seamless roaming of mobile nodes. The network includes a server constituting the core of the network, fixed access points providing the low-level protocol, fixed anchors providing the locating function and nodes comprising sensors and actuators according to the end purpose of the network. The fixed anchors determine a distance measurement with the nodes by time of flight of radio waves, with the nodes behaving as an active radio deflector.

Wireless computer network and method for locating a node in said network

A device for powering an electronic circuit that applies at least a first voltage or a second voltage, different from the first voltage, to the electronic circuit. The device includes a performance monitor that receives an item of information defining a constraint and determines a first duration and a second duration, such that the operation of the electronic circuit at a first frequency associated with the first voltage for the first duration, and at a second frequency associated with the second voltage for the second duration, complies with the constraint. The device applies the first voltage and the first frequency to the circuit for the first duration and the second voltage and the second frequency for the second duration.

Device for powering an electronic circuit, in particular a digital circuit, and associated method

An electronic circuit power supply device configured to selectively apply at least one first voltage or one second voltage to a power supply terminal of the electronic circuit that includes elements for applying to the power supply terminal a voltage variable from a value equal to the first voltage to a value equal to the second voltage and elements designed for selecting application of the second voltage to the power supply terminal when the variable voltage reaches the second voltage.
