Title: Echo canceller
Inventor: SUGAYA FUMIAKI
IPC: H04B14/04
Filed: 1992-08-14
Abstract: An echo canceller according to the invention, including MIC interfaces for a telephone circuit MIC, comprises an echo estimator (65), coupled to a receiving channel by a linear code converter (632), for measuring a linear reception input signal, a subtractor (7), inserted after a linear code converter (631) on a sending channel, for cancelling an echo component in a linear transmission input signal. A high staggered gain is given to the echo estimator in the divergence state, and a relatively low gain in the convergence state in which a non-linear quantisation processor (27), inserted between the subtractor and the echo estimator, produces a new echo estimate on the basis of the estimate done by the echo estimator in order to cancel the echo and the quantisation noise in the linear transmission input signal.

Title: Video camera arrangement for forming three=dimensional images - has three cameras mounted on arm and spaced apart by variable distance and angle of convergence, with automatic objective regulation for depth, centre camera being fixed
Inventor: OLIVIER BOUTE
IPC: H04N13/239
Filed: 1992-12-14
Abstract: Three video cameras (1-3) are detachably mounted on an arm (4) with variable spacings between them. The arm with the cameras is moved to the required position. Video outputs from the two outer movable cameras (1,2) are compared with that from the central fixed camera, and measurements are taken of the separation and angle of convergence of the two outer cameras. The measured values are then used, via a look up table in memory, to produce a revised angle of convergence, by moving the camera position along the arm. The revised angle of convergence is then set, providing a realistic three dimensional output. USE/ADVANTAGE - Improved depth of image making three dimensional pictures of sufficient quality for TVs.

Title: Line guide for fishing reel
Inventor: PLESTAN ALAIN
IPC: A01K89/01
Filed: 1994-08-12
Abstract: The fishing reel has a drum (5), driven in rotation, around a central axis, by the handle (4). The reel also has a curved arch (6) for the recovery of the line.  In this recovery position, the primary end of the arch carries a roller (11), which is fitted to rotate around the central axis (II-II) of the arch, such that during the recovery process, the line is progressively driven around the roller and a guiding ring (12). The roller is cylindrical with a slightly concave profile and has a length, sufficient to allow free axial displacement of the intermediate part (28) of the line. The amplitude of the movement of the line is produced by the variation in the rate of recovery and by the variation of the orientation relative to the front part (18) of the line, between the recovery arch and the guiding ring.
