Inventor: BLUMBERG MARVIN R
IPC: G06F3/02
Filed: 1997-08-28
Abstract: This invention is a speed typing method and apparatus having multiple letters associated with each key of a keyboard. By utilizing multiple characters on each key, fewer than 26-letter keys may be employed. Each key on the keyboard is associated with a numerical code (208). The system uses the numerical code associated with a typed word to access a dictionary, or table of words stored in memory at a memory location corresponding to the input numerical code. The system may display all of the words (216) available to the user in response to the input code. The user then selects (220) one of the available words to be placed in the document. Alternatively the system may enable display of one or more preferred words.

Patent CA-2288635-A1 (CA)
Inventor: DERNERYD SVEN ANDERS GOESTA
IPC: H01Q3/26
Filed: 1998-05-05
Abstract: The invention relates to an apparatus and a method for simultaneously generating, with the same radio antenna apparatus (10), a number of narrow beams and a wide beam, covering substantially the same area covered by the individual pointed beams together. The radio antenna apparatus (10) comprises an antenna array (3), a Butler matrix (2) connected to the antenna array and a set of amplifying modules (1a,...,1h). The activation of each of the inputs (L1,...,L8) of the radio antenna apparatus corresponds to a radiation pattern characterized by a narrow beam with a high antenna gain from the antenna array (3). By simultaneously activating the beam ports with the same signal with suitable phase relationships a superimposition of the radiation patterns to which the activated beam port corresponds is achieved in such a way that a wide beam is generated. Since all amplifying modules (1a,...,1h) are used simultaneously, the lower antenna gain of the wide beam will be compensated by a corresponding higher amplification. The wide beam will therefore have substantially the same range as the narrow beams.

Patent CA-2292867-A1 (CA)
Inventor: TESSIER LYNN P
IPC: E21B43/12
Filed: 1999-12-22
Abstract: Apparatus is provided for stabilizing a rotary or progressive cavity pump suspended from production tubing. The stabilizing apparatus is connected to the pump and comprises a tubular body having a contiguous wall, a longitudinal bore contiguous with the production tubing and a sliding dog disposed in a longitudinal pocket formed in the exterior of the tubular body. One or more longitudinal piston bores are formed within the cylindrical wall and each contains a longitudinally movable piston. Each piston extends into the pocket and pivotally connects to the sliding dog. The piston bore is connected to the longitudinal bore. In operation, fluid pressure drives the pistons, actuating the sliding dog and driving the dog radially outwards to brace against the casing, the radial force produced being proportional with the fluid pressure. Under de-pressurized conditions, upward drag on the sliding dog compresses the pistons, retracting the dog, and permits removal of the tool and pump.

Abstract: The invention concerns a network enabling communications at different rates, with signals transmitted by successive frames each divided into elementary time intervals usable for different communications, A frequency band is allocated to communications between the base stations of a group of cells and mobile stations. Said band is subdivided into blocks of width 2?M-1¿xB¿0?, where B¿0? is a predetermined spectral width and M a whole number greater than 1 selected on the basis of a maximal communication rate. Each of the blocks is divided into carriers of width 2?m(i)-1¿xB¿0?, m(i) being a whole number depending on the block considered such as 1?m(i)?M. The distribution of blocks and carriers in the allocated frequency band is identical for all the cells of the group. In order to support a communication in one of the cells, a predetermined logic channel is selected, according to the required rate, as one or several time intervals on one of the carriers.
