Title: Visual recognition technique for television surveillance - using image base with learning process inputting to classifier comparing image with parameters from process
Inventor: GILLES BUREL
IPC: H04H1/00
Filed: 1992-05-05

Title: Auto-drive or synchronous variable reluctance polyphase stepper motor rotor shaft angular position detector - connects series pole windings to constant amplitude HF AC generator to obtain at terminals of each phase voltage with envelope modulated uniquely by position of rotor teeth relative to stator
Inventor: DOMINIQUE BONOT
IPC: G01D5/20
Filed: 1992-07-31
Abstract: The toothed stator (11) and rotor (31) have similar magnetic circuits mounted on the same shaft (1) which precisely aligns them. Upon each pole (12) of the stator (11) is wound a coil (16). The windings on diametrically opposite poles are connected in series to form one phase of the detector (10). The phases are connected to a constant amplitude high frequency AC generator so that they are synchronised with currents of the same amplitude. This gives by rotation at the terminals of each phase an amplitude modulated voltage whose modulation envelope uniquely depends on the position of the rotor teeth with respect to the stator teeth of each phase. USE/ADVANTAGE - Has simplified electronic circuits which make them insensitive to temperature variations. Serves also as speed detector.

Abstract: System consists of a piston (111) reciprocating in a cylinder (110) by virtue of a power centre (102) comprising a variable output pump (103) driven by a motor (104), and a hydropneumatic accumulator (108). The cylinder (110) is connected to the variable output pump by a port (114) at its lower end, and by apertures (116,118) at different levels above it which are covered alternately by the piston to produce an inversion of the pumps operation, so that on each operating cycle of the hydraulic cylinder energy is recuperated on the downward stroke and used on the upward one. The variable output pump (103) can be one with radial pistons, incorporating a rotor (106) with its inversion controlled automatically by the pressure of the fluid at the level of the two apertures (116,118). The rotor (106) can have a variable eccentricity to give different speeds for the ascent and descent of the piston. ADVANTAGE - Design simplicity, allowing for a recuperation of energy on piston down stroke, with ease of adjustment.
