Patent CA-2369964-A1 (CA)
Title: Pesticidal fusions
Inventor: CHRISTOU PAUL
IPC: C12N15/09
Filed: 2000-04-27
Abstract: Disclosed are polynucleotides encoding a pesticidal fusion polypeptide comprising (i) a toxin domain; and (ii) a heterologous binding domain capable of binding non-specifically to a cell membrane without disrupting that membrane. Preferably the toxin domain is derived from a Bacillus thuringiensis cry toxin (e.g. CryIA (b) or (c)) and the binding domain is derived from a lectin (e.g. ricin toxin B chain). The use of such fusions may help to inhibit the acquisition of resistance in a pest population treated with the polypeptide. A further aspect of the invention is a method of assessing the toxicity of a polypeptide to a pest species by expressing a nucleic acid encoding said polypeptide in a host cell from that species, observing the viability of the cell and correlating the results of the observation with the toxicity of the polypeptide, wherein the viability is determined by assessing esterase activity or membrane integrity.

Title: Illuminating hand-shaking exerciser with triple rotating axle
Inventor: YU HUI-NAN
IPC: A63B22/18
Filed: 2002-03-19
Abstract: An illuminating hand-shaking exerciser with a triple rotating axle mainly comprises a main shell having internal rotary collars connected to shells by an axle. When two semi-spherical covers of two sets of matching shells are closed against each other, a space is provided for internal rotary collars. One shell holds several lighting coils. The internal rotary collars are placed in the order of large, medium and small collars. The small collar has a groove at inner edge to lock an inertial magnetic weight inside.   When the user grasps the shell and shakes it around, the large; medium and small collars will rotate three-dimensionally.Further, due to inertial rotation by the inertial magnetic weight inside the small collar, the entire exerciser will shake vigorously. Meanwhile, the lighting coils will illuminate due to inertial rotation of the magnet. Thus, the exerciser provides hand exercise with entertaining effect of illumination.

Title: Procede et appareil visant a reduire la quantite de ram tout en maintenant un acces rapide aux donnees
Inventor: LEKVEN ERIC JOHN
IPC: G06F17/30
Filed: 2001-01-19
Abstract: L'invention concerne un procédé et un appareil servant à réduire la quantité de RAM nécessaire tout en maintenant un accès rapide aux données. Les enregistrements des données sont souvent sauvegardés dans une mémoire non volatile afin de conserver les contenus des enregistrements des données même lorsque le circuit est désactivé. Dans la présente invention, chaque enregistrement de l'ensemble non volatile des enregistrements de données est introduit dans une fonction H(x) qui génère une valeur d'étiquette. La valeur d'étiquette calculée est sauvegardée dans des emplacements de mémoire prédéterminés de la RAM. Chaque étiquette calculée est plus courte en longueur que l'enregistrement sauvegardé dans la RAM non volatile. Par conséquent, une quantité moindre de RAM est nécessaire pour sauvegarder une valeur d'étiquette pour chaque enregistrement de données que pour sauvegarder l'ensemble des enregistrements de données de la RAM. La valeur de H(y) est calculée lorsqu'une entrée d'enregistrement de données correspondant à y est désirée. La valeur H(y) est alors comparée à toutes les valeurs de la table des valeurs d'étiquettes. Si une correspondance est trouvée, l'enregistrement correspondant à son emplacement dans la RAM non volatile est retrouvé et comparé à y. Si les valeurs ne correspondent pas, on cherche dans la table des valeurs d'étiquettes un autre emplacement correspondant à H(y). Le résultat est une comparaison très rapide avec les contenus de la RAM non volatile ne nécessitant qu'une quantité minimale de RAM.
