Title: Procede de production d'un produit relativement doux, ainsi que produit lui-meme
Inventor: RUTHERFORD GEORGE
IPC: B31F1/07
Filed: 1998-07-16
Abstract: L'invention concerne un produit relativement doux, principalement plat mais tridimensionnel, que l'on obtient au moyen d'un outil d'estampage servant à transformer, par estampage, un produit de départ plat relativement doux afin de créer un motif d'estampage composé d'une multitude de "parallélogrammes articulés". Ces parallélogrammes sont limités par des lignes de matériau comprimé de telle façon que, en cas d'application de forces de traction, le réseau de parallélogrammes articulés se comporte comme un pantographe, un agrandissement de volume secondaire se superposant par un processus d'étirement à l'agrandissement de volume primaire dû à l'estampage.

Title: Multi-well computerized control of fluid pumping
Inventor: STEEN HENRY B III
IPC: E21B47/00
Filed: 1998-09-24
Abstract: A system for controlling one or more borehole pumps (10) includes a computerized controller (120) which, in combination with sensors (20), monitors and controls the activity of the pump, thereby controlling fluid in the borehole. The system is continually in one of three modes: the monitoring mode, the pump mode, and the recovery mode. Within each cycle of modes, the system performs multiple checks on the apparatus involved. The data obtained during the check is stored in appropriate databases as well as checked against predetermined norms. In the event of a malfunction within the apparatus, or other supervised and/or monitored functions, the system can activate a notification system, such as a centralized monitoring facility (102). A pump (10) is disclosed with a fluid sensor (2) to detect the presence of fluid and transmit this presence to the computerized monitoring system (12). A slug sensor (48) notifies the computer (120) of the beginning and end of a predetermined quantity of fluid.
Patent CA-2305207-A1 (CA)
Title: Method and apparatus for optimizing antenna tilt
Inventor: KRONESTEDT FREDRIC
IPC: H01Q3/26
Filed: 1998-09-29
Abstract: In a cellular telecommunications network, uplink interference, as measured by a base station in a target cell, and co-channel interference, as measured by mobile units in a co-channel cell are reduced by increasing the base station antenna tilt angle. However, increasing the base station antenna tilt angle reduces the effective coverage area of the target cell. To obtain an optimum base station antenna tilt angle, interference reduction and target cell coverage area reduction are quantified for each of a number of candidate base station antenna tilt angles. An interference reduction-to-target cell coverage area reduction ratio can then be established for each of the candidate base station antenna tilt angles. The optimum base station antenna tilt angle can then be identified as the one candidate base station antenna tilt angle that reflects the maximum interference reduction-to-target cell coverage area reduction ratio.

Title: Method and device for storing, selecting and playing digital audio in magnetic memory and electronic security system against unauthorized copies
Inventor: VULICH MARCELO HECTOR
IPC: G10L19/02
Filed: 2000-07-12
Abstract: A method and a device for storing audio information in magnetic memory, an electronic arrangement for protecting the computing program and a method of protection against non-authorized duplications is presented. The device of the invention allows, by means of an entrance signal, preferably a bar code reader, to select the information and the content of a product, preferably a CD of commercial music, that is stored in a magnetic memory in digital form. The audio information, preferably music, is converted into computing formatted information by means of a well-known software and is stored compressed with a high compression ratio. The original audio parameters that are lost during the compression are stored in a complementary memory and are outputted simultaneously, and therefore the audible signal that reaches the user through earphones and/or loudspeakers recovers its high quality sound, reproducing the file with no need for decompressing it. The method also offers technical control checking for the device and statistics logging based on the playback requests carried out by the users.  The integrity of software and the authenticity of the device are protected by means of an anti-copy system that is based on a microprocessor based security card.

Title: Uniplanar dual strip antenna
Inventor: TRAN ALLEN
IPC: H01Q1/38
Filed: 1999-02-19
Abstract: A uniplanar dual strip antenna (400) that has a two-dimensional structure. The antenna is comprised of a first and a second metallic strip (404, 408), each printed or etched on a thin planar substrate (412). The first and second strips (404, 408) are separated by a predetermined gap (T) and are used as conductors of a two-wire transmission line. A coplanar waveguide (416, 1520) is coupled to the uniplanar dual strip antenna (400). The coplanar waveguide (416, 1520) is constructed by printing or etching metal on the substrate. The positive terminal (420, 1522) of the waveguide is electrically connected to the first strip. The negative terminal (424, 428) of the waveguide is electrically connected to both the first and second strips. The uniplanar dual strip antenna (400) according to the present invention provides an increase in bandwidth over typical quarter wavelength or half wavelength patch antennas. Experimental results have shown that the uniplanar dual strip antenna (400) has a bandwidth of approximately 8 - 20 % that is extremely desirable for PCs and cellular phones.
