Filed: 1997-10-03
Abstract: La présente invention concerne un procédé pour transmettre des signaux audio à multiples résolutions via des dispositifs sans fil dans un système haute fréquence, selon lequel les signaux audio sont décomposés en niveaux de résolution (38). Les signaux audio sont décomposés en niveaux comprenant un signal de base à une vitesse de transmission de base et un ou plusieurs détails de signaux. Le signal de base représente la résolution ou la qualité du signal la plus grossière. Chaque détail de signal, une fois ajouté au signal de base, améliore la résolution du signal en augmentant le détail et la vitesse de transmission. Une unité de réception audio (50) transmet une demande pour une transmission audio à l'unité de transmission audio (30). En réponse à la demande initiale, le signal de base est transmis à l'unité de réception audio. Lorsque le signal de base est insuffisant, la qualité du son peut être augmentée de manière incrémentielle en envoyant une autre demande de transmission de détails de signaux supplémentaires. Ce détail de signal supplémentaire est ensuite recombiné au signal de base au niveau de l'unité de transmission audio pour conférer un niveau de qualité sonore supérieur au signal. Ce signal de qualité supérieure est alors transmis à l'unité de réception audio.

IPC: A61K31/203
Filed: 1998-05-11
Abstract: Various skin disorders, excluding acne are treated by topical application to the skin of a retinoid-composition including a retinoid in a dermatologically acceptable vehicle at such a concentration and applied in such a way as to induce desquamation of the skin to ameliorate the disorder. Preferably, the compositions contain greater than 0.1 weight percent tretinoin, and more preferably at least 0.2 weight percent tretinoin. The vehicle is preferably a solvent for the retinoid such as an alcohol/glycol or hydroalcoholic vehicle, but it is also possible to apply the retinoid in a non-solvent vehicle such as emulsifying or suspending the retinoid in a cream, dressing, gel, ointment or liquid polymer, with or without penetration enhancers. The treatment achieves rapid amelioration of skin disorders such as photodamaged skin, hyperpigmentation, rosacea, premalignant cancers including actinic keratoses, wrinkles, superficial scarring, epidermal atrophy and atypia, and keratosis pilaris, by daily or every other day application for about one to two months. Thereafter, the high strength applications may be tapered off, and the treated skin maintained with more conventional lower concentration compositions.

Title: Anti-gravity device
Inventor: ALBEE LYLE J
IPC: H02N11/00
Filed: 1999-12-29
Abstract: Just a few lines to explain how this Rock Motor works. I never was sure until I built this Rock Motor and figured out how it worked, then I realized what was going on. That is with the currents the Rock Motor creates the electric magnet current when running. The top rocks make current, and the current slides down to the center rock and is thrown off. The bottom rocks make electric current that climbs up to the center rock and is thrown out the same as the top current. Now, all of these rocks are magnetic so the current has the right mix to nullify gravity in the field that has been made. Being positive nullifies gravity. Now, the negative electricity is made by the power of the line of force that creates the constant spin of the rocks that are all positive, and negatively charged. Now the bottom round-rock rolls, but will stay where you put it, so this gives the direction that you want it to go. Put the round rock in the center of the saucer and the shift will go straight up. Wherever you put the round rock, so goes the shift. No one explained this to me. When you da this with your own hands, you find out what is going on.

Abstract: Abrasion resistant laminates which are aesthetically pleasing, water-resistant/water-repellant, and flexible are formed by laminating a wear-resistant durable multi-layer top assembly to a base layer formed from an inexpensive, water-resistant, polymeric substrate. The durable multi-layer wear-resistant top layer assembly comprises a wear-resistant upper layer, a decorative layer, and a core layer. The polymeric base layer comprises a water-resistant substrate which is positioned beneath the top layer assembly and is laminated thereto with a water-resistant adhesive. This abrasion resistant laminate could be applicable in a variety of situations wherever a decorative and/or abrasion resistant product could be used and would be particularly useful in the floor covering industry.
