Abstract: A ventilation device includes at least one aerator having a channel capable of conveying an air flow from an inlet opening to an outlet opening, a hollow air guiding core housed in the channel and defining two air guiding surfaces delimiting, with this channel, two flow paths capable of transporting, respectively, to the outlet opening, first and second quantities of air from the inlet opening, a fin mounted so as to be able to pivot upstream from the core and arranged so as to make it possible to adjust the ratio between the first and second quantities of air, depending on the position of same, and a control module incorporated at least partially into the core of at least the aerator and having a control panel constituted at least partially by a downstream end wall of the core and being provided with a control device.

Abstract: A support for a mobile device has a front face bearing a stationary jaw. The support includes a moving jaw facing the stationary jaw, mounted in translation on the front face of the support. The moving jaw is able to receive a side edge of the mobile device, and the support further includes at least one guide ramp secured to the support, on which the moving jaw is slidingly mounted between a separated position, in which the mobile device is placed against the moving jaw, and a maintaining position, in which the mobile device is kept pressed against the stationary jaw. The support includes at least one return element, secured to the support, cooperating with the moving jaw over the entire length of the guide ramp and able to grip the mobile device against the stationary jaw.

Abstract: The method of calibration of a second order intermodulation intercept point (IIP2) of a radio transceiver comprises the steps of: generating a second order intermodulation (IM2) reference signal (STXIM2-REF) from a transmission baseband signal (STXBB-REF); estimating a second order intermodulation power from the second order intermodulation reference signal (STXIM2-REF) and a radio transceiver output signal (Output); tuning a second order intermodulation intercept point tuner to find a lowest second order intermodulation power; extracting an optimum second order intermodulation intercept point corresponding to the lowest second order intermodulation power.
