Abstract: A cellular radio-telephone system has a plurality of cells each of which has S sectors. The cells are grouped into a plurality of clusters each of which has N adjoining cells. Each cell has a set of assigned system frequencies with respective frequency subsets assigned to its sectors so that N groups of co-channel cells exist with each co-channel cell group including one cell from each cluster having channel frequencies corresponding to those for its co-channel cell group. Respective base station antennas are located in the respective sectors of the respective cells, and each of the cell sectors has a plurality of subscriber station directional antennas disposed at predetermined locations within the sector for communication linkage with the associated base station antenna. The cells are generally formed in rows and columns and further are formed to provide a predetermined relative orientation pattern for co-channel cell sectors. Co-channel cells form a first cell tier around a preselected center co-channel cell with a common direction operative as a reference orientation direction for co-channel sectors therein. Co-channel sectors in successive co-channel cells about the first tier being successively oriented in alternating first and second directions with sectors rotated by at least one sector rotation from the reference direction in the clockwise or counter-clockwise direction.

Title: Method and apparatus for testing electronic memories for the presence of multiple cell coupling faults
Inventor: COCKBURN BRUCE FORDYCE
IPC: G11C29/12
Filed: 1994-08-03
Abstract: A method of testing a random access memory (RAM) for single V-coupling faults by establishing a first current value for each cell, for each cell and for each of m data backgrounds, generating a data bit corresponding  to  an  element  of  an  (n,  V  -  1)-exhaustive matrix, and for each of m data backgrounds: (1) applying a read write sequence to each cell; and (2) for each background except the mth background, updating the current value of all cells according to the data bits corresponding to that cell; reading each cell of the RAM; and discarding or repairing the RAM if a cell coupling fault is apparent from the series of values read from the cells of the RAM. Data bits are generated by a matrix reconstruction method or a pseudo-random generator using a hashing of the address of the cell to which the data bit is to be applied. The logical function may be the element of the (n, V -1)-exhaustive matrix irrespective of the current of the cell or an exclusive-or of the complement of the background code logic bit and the first current value of the cell. Apparatus for testing a random access memory (RAM)  has a PROM containing background code logic bits corresponding to an (n0, V - 1)-exhaustive matrix where n0  n, the matrix having n0 rows and m0 columns; and a data bit generator for generating data bits from the matrix stored in the PROM. A built in apparatus for testing a random access memory (RAM) having n cells includes a data bit generator that generates pseudo-random data bits from a hashing of the address of the RAM cell to which the data bit is to be applied.

Patent CA-2133524-A1 (CA)
Inventor: KUSE KAZUKI
IPC: A44B19/60
Filed: 1994-10-03
Abstract: A method of forming end stops to a continuous slide fastener chain including element-free space portions at long-itudinally spaced intervals, wherein as the chain is fed in the backward direction, a pair of rows of interengaged coupling elements extending on the downstream side of an element-free space portion is spread open by a chain splitting apparatus for subsequent molding of a separable end stop whereas a pair of rows of coupling elements on the upstream side of the ele-ment-free space portion is kept in engaged condition.  After the separable end stop is molded, the chain is fed in the for-ward direction during which time a sprue portion and gate portions formed integrally with the separable end stop are caught by a chain splitting member of the chain splitting apparatus.  The chain splitting member is then lowered to automatically remove the sprue portion and gate portions from the separable end stop.

Title: Vertical-cavity surface-emitting laser array display system
Inventor: JEWELL JACK L
IPC: G02B27/00
Filed: 1993-04-20
Abstract: A visual display system is disclosed which utilizes one- and/or two-dimensional arrays of visible emitting vertical-cavity surface-emitting lasers (VCSELs) (200) in order to provide a desired visual display within an observer's field of view (220). Sweep and subscanning techniques are employed, individually or in combination, to create a full M x N image from 1 x L or K x L arrays of VCSELs, where M and N are multiple integers of K and L, respectively. Preferably, the VCSELs (200) are contained within a display housing which may be attached to the head of the user by an attachment mechanism or may alternatively be hand held or mounted to a surface. The circular symmetry and low divergence of the emitted VCSEL radiation as well as the availability of multiple wavelengths, particularly, red, blue, and green, allow high resolution monochrome or color images to be generated.

The one ion species whose sign is opposite to that of the zeta potential of the material is combined with a vector (13) having a zeta potential (14) with the same sign as that of the material. Stones or structures may thus be consolidated.
Patent CA-2139999-A1 (CA)
Title: Axle counter with variable threshold setting
Inventor: UEBEL HELMUT
IPC: B61L1/16
Filed: 1995-01-11
Abstract: An axle counter which compares axle passage pulses generated in an electromagnetic rail contact with a predetermined threshold value and, when this threshold value is exceeded, feeds an axle counter pulse to presence-of-trains indicating equipment, is equipped with overwritable memories (SMA, SMI) for storing this threshold value. In response to a setup command entered manually by depressing a key or transferred from a distant control facility (STW), the memories can be overwritten with a current axle passage pulse value or a statistically determined value corresponding to an average axle passage pulse. This eliminates the need to reposition the rail contact at regular intervals and permits this repositioning to be replaced by an adaptation of the threshold value to the axle passage pulses, which change as a result of rail wear, for example.
