Title: In-home theater surround sound speaker system
Inventor: GREENBERGER HAL P
IPC: H04R5/04
Filed: 1996-09-06
Abstract: An apparatus (10) for realistically reproducing sound, particularly for sound based on a stereophonic signal having dialog and effects and associated with an accompanying video image. The apparatus includes a front speaker (20) located in proximity to the video image for providing acoustic output based upon a summation signal of the component left and right (L+R) channels of the audio signal. A rear speaker (26) located to the rear of the viewing area provides acoustic output based upon a difference signal, (L-R) or (R-L), between the left and right channels. Left and right speakers (22 and 24) are located to the respective left and right sides of the viewing area. The left and right channels speakers (22 and 24) reproduce in one embodiment the respective left and right channels of the audio signal and in a second embodiment reproduce a difference signal, (L-BR) or (R-BL), where B is a gain which may vary or may be a value fixed between zero and unity. Output to the left and right speakers (22 and 24) is band limited to substantially filter out frequency components below a predetermined threshold. A bass speaker (18) may also be provided to output the low frequency components of a (L+R) summation signal. The (L+R) summation signal input to the front speaker assists in localizing dialog to the video image. The (L-BR) or (R-BL) difference signal substantially removes dialog sound so that the side and rear speaker output primarily comprises sonic ambience and surround sound effects.  Band limiting the left and right speakers further assists in localizing dialog to the video image. Alternatively, in yet another embodiment, a monophonic signal may be applied to at least one embodiment of the system to enable production of a spatially enhanced surround sound effect.

IPC: A61F5/01
Filed: 1996-12-06
Abstract: Orthèse du genou comportant une sangle de suspension servant à fixer l'appareil orthopédique à la jambe de l'utilisateur. Cette sangle de suspension comprend une partie en forme de bande qui traverse les faces internes des bras d'appui tibiaux et est reliée au bras tibial latéral du côté intérieur de la jambe en un point de raccordement plus bas que le point de raccordement de la bande au bras tibial latéral du côté extérieur de la jambe. Ce positionnement assure une suspension et un soutien perfectionnés car il maximise la surface de contact entre la sangle de suspension et la jambe de l'utilisateur et engendre une force avantageuse orientée dans le sens antéro-postérieur, sans pour autant comprimer le nerf péronier de la jambe. Par ailleurs, on peut utiliser une pièce d'écartement préformée pour favoriser la création de la force orientée dans le sens antéro-postérieur, et pour améliorer globalement le soutien et la suspension.
Patent CA-2215309-A1 (CA)
Inventor: BARMAN SHIKHA P
IPC: C09D171/00
Filed: 1996-03-22
Abstract: An improved barrier or drug delivery system which is highly adherent to the surface to which it is applied is disclosed, along with methods for making the barrier. In the preferred embodiment, tissue is stained with a photoinitiator, then the polymer solution or gel having added thereto a defined amount of the same or a different photoinitiator is applied to the tissue. On exposure to light, the resulting system polymerizes at the surface, giving excellent adherence, and also forms a gel in the rest of the applied volume. Thus a gel barrier of arbitrary thickness can be applied to a surface while maintaining high adherence at the interface. This process is referred to herein as "priming". the polymerizable barrier materials are highly useful for sealing tissue surfaces and junctions against leaks of fluids. In another embodiment, "priming" can be used to reliably adhere preformed barriers to tissue or other surfaces, or to adhere tissue surfaces to each other. A first surface and a barrier, or another surface, are prestained with initiator, and a thin layer of gelable monomer containing initiator is placed between them. Strong adhesion is obtained between the two surfaces on gelation of the monomer. In a similar fashion, tissue surfaces can be adhered to each other in repair of wounds and formation of anastomoses.  Methods for use of non-photochemical systems and combined chemical/photochemical systems are described.

Title: Method and apparatus for blasting hard rock
Inventor: PRONKO STEVEN G E
IPC: E21C37/18
Filed: 1996-06-04
Abstract: A method and apparatus for blasting of hard rock using a highly insensitive energetic material ignited with a moderately high energy electrical discharge causing the fracturing and break up of the haul rock is provided. The blasting apparatus (10) comprises a reusable blasting probe (14) including a high voltage electrode (44) and a ground return electrode (46) separated by an insulating tube (40). The two electrodes of the blasting probe (14) are in electrical contact with a continuous volume (70) of highly insensitive yet combustible material such as a metal powder and oxidizer mixture. The metal particles within the metal powder and oxidizer mixture form a plurality of fusible metal paths between the high voltage electrode (44) and the ground return when subjected to an electric current delivered from a large capacitor bank (16) coupled to the high voltage electrode (44). The plurality of fused metal paths act much like a fuse in that they provide a sufficiently high electrical resistance to allow coupling of the electrical energy from the capacitor bank (16) to the metal powder and oxidizer mixture causing an increased dissipation of heat which initiates an exothermic reaction of the metal powder and oxidizer mixture generating high pressure gases fracturing the surrounding rock.

Title: Submicron liposome suspensions obtained from preliposome lyophilizates
Inventor: ZOU YIYU
IPC: A61K31/65
Filed: 1996-06-06
Abstract: This invention provides an aqueous/t-butanol solvent-system, facile reconstitute, submicron-reconstitute preliposome-lyophilate and method of its preparation and use. In one embodiment, a modified method for the preparation of a submicron and stable liposome formulation of the non cross-resistant anthracycline Annamycin is described. The optimal lipid composition was DMPC:DMPG at a 7:3 molar ratio and the optimal lipid:drug weight ratio 50:1. The selected formulation is a preliposome lyophilized powder that contains the phospholipids, Annamycin, and 1.7 mg Tween 20 per mg of Annamycin. The liposome suspension is obtained on the day of use by adding normal saline at 37 °C (1 ml per mg Annamycin) and hand-shaking for one minute. The presence of Tween 20 is essential in shortening the reconstitution step (from > 2 hours to 1 minute), avoiding the early formation of free drug crystals, and reducing the median particle size (from 1.5 µm to 0.15-0.20 µm) without destruction of the liposome vesicles. The chemical stability of the preliposome powder at room temperature was >  3 months and the chemical and physical stability of the liposome suspension at room temperature > 24 hours. The in vitro cytotoxicity of the formulation was equivalent to that prepared by the standard evaporation method. The results of the study indicate that small amounts of surfactant may be used to enhance the reconstitution step and reduce the liposome size of lyophilized liposome formulations of lipophilic drugs.

Abstract: This is a device to assist the loading of a light boat (canoe) onto the top of a vehicle by only one person. In this invention four attachable legs are pushed into the bottom lift tube base thus supporting the lift tubes in the vertical position. The height of the stand is adjustable by placing the height adjust pin into the desired through hole.  Once adjusted the rotary shaft is moved to its horizontal position, protruding out towards the side. Separately, the boat plate is firmly fixed to one end of the boat by the use of a strap and buckle. With the use of your hands, you rotate the boat on the ground to its side, then lift the boat until the connect pin falls into the hole on the rotary shaft. Once in, a clip is used to secure the boat plate to the stand. The user then moves to the side of the boat and lifts and rotates it upwards until the lock collar falls into its locking position.  The boat is now firmly anchored in the top position. Now the unsupported end can be lifted and rotated over the top of the vehicle by the use of one person. Once on the top of the vehicle, the stand and boat plate can easily be removed and disassembled for easy transport.
