Patent FR-2614187-A1 (FR)
Title: Support stick device which can be converted into a three-legged seat
IPC: A47C9/10
Filed: 1987-04-27
Abstract: The invention consists, starting with a conventional straight and rigid support stick 1 equipped with a rubber tip 7 and a handle 8, in capping the whole assembly with a rigid element in the form of an arch 2 whose two branches hang down on either side of the stick. These two elements are connected together by a common horizontal articulation 3 located on the length of each of them. In the stick position, the two elements are located in the same plane, and in the seat position they assume a position in the form of an "X" with respect to the common articulation. A flexible element stretched between the two upper branches then acts as a seat part, the two lower branches acting as legs for support on the ground. A strap stretched between the two lower branches improves safety and stability of the assembly. The applications of such a device are numerous, since it is intended for those individuals who go walking, hunting, who play golf, and who go to outdoor shows (horse races, displays (meetings), etc.), or to the beach. Extremely compact for transportation and storage, it may also serve as an additional seat in the home, in communal areas or in public places.

Title: Method and device for establishing the pressure/diameter relationship of an artery by non-invasive measurements
Inventor: MEISTER JEAN-JACQUES
IPC: A61B5/022
Filed: 1989-03-13
Abstract: The method for establishing the pressure/diameter relationship of an artery uses the measurement results of a non-invasive sensor 3 for the diameter of the artery, for example on the humeral artery, and a non-invasive sensor 4 for the blood pressure, for example carried out at the end of a finger. With the measurement locations separated by a distance DELTA x, the method provides for correction of the pressure measurements to what they would be if they were carried out at the location where the diameter measurements were carried out. The method furthermore provides for a correction taking account of the mechanical properties of the artery, defined by parameters alpha , beta , gamma ,... which are calculated, if required by successive iterations, until the pressure/diameter curve appears free from any measurement artifice (hysteresis). The pressure/diameter relationship makes it possible to calculate the mechanical properties of the arteries, in particular using curves of compliance and a speed of propagation as a function of the pressure.

Patent FR-2650634-A1 (FR)
Title: Improved micropump
Inventor: LINTEL HARALD VAN
IPC: F04B43/04
Filed: 1989-08-07
Abstract: In this micropump, pumping is obtained by virtue of the deformation of a small plate 12 with the aid of a piezoelectric pellet 13. Deformation gives rise to a variation in volume of a pumping chamber 15 delimited in a small plate 11 made from a material capable of being machined by photolithography methods. The outlet 3 of the pump is selectively closed off by a diaphragm valve 18 which is in direct communication with another valve 16 through the pumping chamber. The said valve 16 selectively makes this pumping chamber communicate with the inlet 2 of the pump. The membrane of the outlet valve 18 is associated with a layer of oxide 17 which prestresses it in the closed direction. In this way, the valve exerts a regulation effect on the operation of the pump making the output practically independent of the pressure of the outlet 3. Application to the injection of medicinal products in precise doses.
