Title: Isolated systems which are automatically propelled by inertia forces
Inventor: CLAUDE LAFFORGUE JEAN
IPC: F03G3/00
Filed: 1989-08-30
Abstract: Device and method making it possible to obtain a break in symmetry of the interaction forces within an isolated system. Let there be (Figure 1) a mass ( epsilon M) constrained to move with a constant angular velocity about a mass ( epsilon m) centred at (O). The mass ( epsilon M) slides along the spoke (R) connected to (O). The masses ( epsilon M) and ( epsilon m) are connected by a spring. It is assumed that ( epsilon M) is the stator and ( epsilon m) the rotor of a linear electric motor. ( epsilon M) is accelerated and decelerated along (R) during each half cycle such that (M), the centre of gravity of ( epsilon M), follows an ellipse and its speed along (R) is zero at theta =0, pi ,2 pi with theta =XOM. It is demonstrated that the energy balances are zero at each cycle, and above all that the resultant force (FR) is not zero on (OX). By leaving the isolated system to move at constant velocity (V) the energy saving is equal to W=o@<t>FR.V.dt.

IPC: G07B15/06
Filed: 1991-01-18
Abstract: L'invention concerne un système de communication entre une borne fixe et des mobiles qui peuvent se présenter simultanément dans le rayon d'action de la borne. Selon l'invention, le système utilise un protocole d'échanges qui commence par un signal d'initialisation (INIT) commun aux différents mobiles qui se présentent et qui continue par l'émission d'un signal d'identification par chaque mobile, cette émission étant effectuée au bout d'une durée (T + Nt) liée à la valeur (N) d'une partie d'un code spécifique intrinsèque associé au mobile, cette durée étant mesurée à partir du signal d'initialisation. De préférence, le mobile émet le début de son code spécifique, par exemple le premier caractère de ce code, suivi d'un mot aléatoire ayant des caractéristiques imposées telles que la borne puisse détecter si plusieurs mobiles ont émis simultanément le même premier caractère. La borne leur demande alors d'émettre un deuxième caractère pour les distinguer l'un de l'autre. Des échanges personnalisés peuvent alors commencer quand tous les mobiles sont identifiés.

Patent FR-2679345-A1 (FR)
Title: System and process for controlling spacecraft attitude
Inventor: EVAN GOODZEIT NEIL
IPC: B64G1/28
Filed: 1992-05-12
Abstract: This process for controlling spacecraft attitude uses one or more reaction wheels or inertia wheel. The viscous friction (dependent on speed) in the wheel bearings reduces the actual torque which is communicated to the spacecraft in response to a torque demand signal. Friction compensation is effected by applying the torque demand signal to a model of a frictionless ideal wheel, and by calculating the speed attained by the ideal wheel in response to the torque demand. An error signal is generated from the difference between the ideal wheel speed and the actual wheel speed. The error signal is added to the torque demand signal to produce the wheel drive signal. This results in a closed-loop feedback system in which the actual wheel speed tends to the ideal wheel speed, thus giving rise on the spacecraft to a torque which is substantially equal to the demanded torque.
