Abstract: The invention relates to the in-service monitoring of the condition of a tire of a wheel of a vehicle. To this end it proposes a process and, in particular, a device comprising: a sensor (4) mounted on the wheel, coupling means (BVF2, BRF2) for transmitting to the vehicle indications derived from this sensor (4), and electrical energizing means (BVF1, BRF1). According to the invention, the sensor (4) is a miniature acceleration-sensitive sensor implanted in the tread of the tire or in the vicinity of the tread. The coupling means, mounted on the wheel, then transmit indications relating to the measurements made at the moment at which the tread is in contact with the ground.
Abstract: A reader for contactless badges which includes a transmitter and receiver. The transmitter and receiver operate on the same carrier frequency, and are connected by a coupling circuit to an antenna. The reader further includes a management device for interacting with the transmitter and receiver for establishing a dialog with a badge. The coupling circuit to the antenna includes a delaying element, traversed by the connection between the transmitter and the antenna, while the receiver includes two channels, starting off on either side of the delaying element. The management device is then arranged to selectively operate the reception channels according to selected criterion.

Abstract: A landing aid device comprises processing means, which receive aircraft path data, and data regarding the position of at least one runway towards which the aircraft is steering. These processing means comprise calculation means which supply a state signal, comprising at least one condition which is dependent on the path data and on the runway data, this function being chosen so as to express the fact that the path of the aircraft converges towards the runway.
