Title: Device for assembling furniture panels or the like
Inventor: SOMMET PIERRE
IPC: F16B12/20
Filed: 1985-01-04
Abstract: Assembly device comprising two complementary parts intended to be mounted in advance on each of the panels to be assembled, and the first of which bears an assembling pin capable of being fastened to the second part. This second part 2 contains elastic catching means 14 intended to interact with a groove 12 arranged on the projecting end 11 of the assembling pin 10 borne by the first piece 1 in order to ensure that the two corresponding panels 5, 6 are immediately hooked to one another as soon as the assembling pin engages inside the second part of the present device.

Patent FR-2723208-A1 (FR)
Title: Location/direction detection system for pilot helmet sights
Inventor: BOUVIER SYLVAIN
IPC: G01S3/786
Filed: 1986-06-17
Abstract: The system enables an accurate spatial referencing of a direction associated with a moving body, eg. a helmet aiming sight. It uses two sensors (3A, 3B) of solid matrix (7A, 7B) type made of charge-coupled devices. These sensors are carried by the structure eg. an aircraft cockpit, and are advantageously formed by miniature cameras. The helmet (2) carries light-emitting bands placed parallel to the direction (DR) to be referenced, these bands being made from either a fluorescent or back-reflecting material. In the latter case, a light-emitting source (15) eg. infrared, is used to illuminate them. The referencing is based on the fact that the analysis of the image of the bands on the sensors enables the definition of at least two secant planes (PA, PB, Fig.3, not shown) each passing through any of the image bands and the associated corresponding optical centre and that their straight line of intersection is a line parallel to the direction to be referenced. A less accurate system employing but one sensor (Fig. 4, not shown) is also described.
