Patent CA-2134991-A1 (CA)
Title: Systeme de propulsion spaciale par champ magnetique (spscm)
Inventor: LADOUCEUR RICHARD
IPC: B64G1/32
Filed: 1994-11-03
Abstract: Le Système de Propulsion Spatiale par Champ Magnétique (SPSCM) est une invention qui se distingue de part son fonctionnement et ses applications. Son fonctionnement est unique en ce qu'il fait appel principalement à deux éléments: premièrement, le SPSCM utilise des bobines de fil conducteur partiellement recouvertes de blindage magnétique à l'intérieur desquelles circulent un courant électrique, et deuxièmement le SPSCM fait appel au champ magnétique d'un corps céleste. La combinaison de ces deux éléments lui permet d'obtenir une force de propulsion (translation).   Le rôle du blindage magnétique est d'annuler l'action du champ magnétique à l'intérieur des régions recouvertes par le blindage. Lorsqu'une bobine est partiellement recouverte de blindage magnétique, alors la force magnétique agit seulement sur les segments de la bobine non recouverts de blindage. Donc, en présence d'un champ magnétique d'un corps céleste tel le champ magnétique terrestre une bobine partiellement blindée ressent une force de propulsion Le SPSCM tel que présenté dans ce mémoire descriptif, est composé de 24 bobines partiellement blindées. Les segments non-blindés, c'est à dire les segments permettant à la force magnétique d'agir sur chaque bobine, sont géométriquement orientés de façon à obtenir instantanément et sur commande, une force de translation dans le plan normal au champ magnétique et une force de rotation selon les trois axes.   Le SPSCM n'utilise aucun carburant conventionnel, il utilise plutôt un courant électrique et le champ magnétique d'un coprs céleste à titre de carburant. Cette caractérisitque combinée à l'utilisation d'un blindage magnétique distingue le SPSCM de tout autre système de propulsion spatial.

Title: A representational approach to dna analysis
Inventor: WIGLER MICHAEL
IPC: C12Q1/68
Filed: 1993-11-08
Abstract: Methodology is provided for developing probes for identifying sequence differences between two related DNA populations, sets of DNA fragments or collections of restriction-endonuclease-cleaved DNA or cDNA. The method employs an initial stage to obtain a representation of both DNA populations, namely using the PCR to produce relatively short fragments, referred to as amplicons. Tester amplicons containing target DNA, sequences of interest, are ligated to adaptors and mixed with excess driver amplicons under melting and annealing conditions, followed by PCR amplification. The process may be repeated so as to greatly enrich the target DNA.  Optionally, the target DNA may then be cloned and the DNA used as probes.

Title: Innovative neuron circuit architectures
Inventor: BOULET JEAN YVES
IPC: G06V10/764
Filed: 1995-05-16
Abstract: In a neural network comprised of a plurality of neuron circuits, there is disclosed an improved neuron circuit architecture (11) that generates local result signals, e.g. of the fire (F) type and a local output signal of the distance or category type. The neuron circuit which is connected to buses which transport input data (e.g. the input category) and control signals includes the following circuits. A multi-norm distance evaluation circuit (300) calculates the distance D between the input vector (A) and the prototype vector (B) stored in a R/W (weight) memory circuit (250). A distance compare circuit (300) compares the distance D with either the actual influence field (AIF) of the stored prototype vector or the lower limit thereof (MinIF) to generate first and secondintermediate signals (LT, LTE). An identification circuit (400) processes the said intermediate result signals, the input category signal (CAT), the local category signal (C) and a feedback signal (OR) to generate the local result signals which represent the response of a neuron circuit to the presentation of an input vector. A minimum distance determination circuit (500) is adapted to determine the minimum distance Dmin among all the distances calculated by all the neuron circuits of the neural network to generate a local output signal (NOUT) of the distance type. The same processing applies to categories . The feed-back signal which is collectively generated by all the neuron circuits results of ORing all the local distances/categories. A daisy chain circuit (600) is serially connected to the corresponding daisy chain circuits of the two adjacent neuron circuits to structure the neural network as a chain. Its role is to determine the neuron circuit state: free (in particular, the first free in the chain) and engaged. Finally, a context circuitry (100/150) is capable to allow or not the neuron circuit to participate with the other neuron circuits in the generation of the said feedback signal.
