Patent FR-2616906-A1 (FR)
Title: Pressure and deformation sensor
IPC: G01L9/00
Filed: 1987-06-17
Abstract: The invention relates to fluid or mechanical pressure sensors, making it possible to obtain information on an upper or lower limit pressure. It comprises a threaded piece 9 forming a container. This piece is passed through by two enamelled copper wires 11 and 12 which are the input and output of the electrical current. A plug of adhesive 10 seals the passage of the two wires which have two of their ends respectively welded onto membranes 4 and 6 by weld points 15 and 16. A support 8, fitted into the piece 9, accommodates, adhesively bonded together, the membrane 6, the O-ring 5, the membrane 4 and the spring 3. The spring, integral with the ball joint 2 hinged in the plug 1 makes it possible, by manipulating the latter, to adjust (in addition to the pressure of the fluid occupying the input 13 and the recess 14) the compression, or resistance to passing of the electrical current, of the small coal 7. Amongst the most important applications of the invention, mention may be made of the remote monitoring of the pressure in tyres and the monitoring of the movement of a movable object.

Patent FR-2635727-A1 (FR)
Title: Method and device for checking the tyre inflation pressure of a stationary vehicle
IPC: B60C23/06
Filed: 1988-08-26
Abstract: The tyre 1 suspension 2 assembly undergoes a deformation measured at 3 as a function of the force measured at 4 exerted by the lifting device 5; the driver of the vehicle has use of a control 6 and an inflation pressure indicator 7. Since the said deformation is different depending on the inflation pressure, the detection of an underinflation is obtained by measuring the difference in deformation as a function of the variation in load on the tyre obtained by the lifting device which is normally intended just for changing the wheel. The method and the clevises which form the subject of the invention make it possible for a driver to check, before driving off, that his vehicle does not have any underinflated wheels.
