Title: Method and apparatus for locating a desired record in a telephone directory
Inventor: RAHRER TIMOTHY JOSEPH
IPC: H04M1/2746
Filed: 1997-12-04
Abstract: A method and apparatus for locating a desired record amongst a plurality of records in a telephone directory involves associating a frequency field with each of the records, the frequency field being operable to store a frequency metric. A characteristic field is also associated with each of the records, the characteristic field being operable to store a characteristic representation of at least one identifying characteristic of a rendering associated with the record. An input representation of a rendering purporting to identify the desired record is produced and the input representation is compared with the contents of the characteristic fields of at least some of the records and confidence metrics are assigned to the records respectively, each of the confidence metrics representing a respective probability that a respective record is the desired record. A determination is then made as to which of the records have the first and second highest confidence metrics. The frequency fields of the records having the first and second highest confidence metrics are then read and the record with the highest frequency metric is identified as the desired record. Instruction codes stored on a computer-readable memory medium may be used to configure a general purpose computer to effect the method.

Title: Two dimensional interleave process for cdma transmissions of one dimensional timeslot data signal
Inventor: RAKIB SELIM SHLOMO
IPC: H04J3/00
Filed: 1999-09-09
Abstract: ABSTRACT      A method and apparatus for interleaving symbols from a one dimensional TDMA 802.14 or MCNS minislot or other TDMA stream into two dimensional arrays in code and time for transmission on a code division multiplexed digital data transmission system. There are two methods disclosed. The first calculates i and j values for storage in RAM as a function of the symbol index in the TDMA stream, the number of codes to be employed, the column space design parameter representing the number of columns in the array, i.e., symbol times, that could be adversely affected by burst noise, and a calculated total number of columns in the array. The result is an array in which no indices of two symbols within any column or between columns of the column space are closer together than a design parameter vertical distance. The other method is similar but interleaves on both a column space as well as a row space so as to spread out the effects of both burst noise and intercode interference so that any errors that result are within the range of the redundant ECC bits to detect and correct.

Patent CA-2283960-A1 (CA)
Inventor: SIEGMUND GERD
IPC: H04M11/00
Filed: 1999-09-27
Abstract: The invention relates to a method of modifying service data stored in a server and to a server (CS) and a terminal (TER) to carrying out this method. Using the service data stored in it, the server (CS) can provide service functions to a telecommunications terminal over a service channel (VL). A data terminal (DT) sets up a data connection (CON) to the server (CS), and the data terminal sends to the server a request to access the service data. After reception of the access request by the server, the server and the data terminal process the data by interaction wherein the server outputs the data to the data terminal and the data terminal sends data to the server at least when a data modification was entered at the data terminal. Modified data are stored by the server. Either the server or the data terminal releases the data connection.

Patent CA-2297679-A1 (CA)
Title: Flexible interlocking wall system
Inventor: CERRATO DOMINIC
IPC: E04B2/08
Filed: 1998-09-08
Abstract: A masonry wall system is disclosed incorporating a plurality of courses of masonry blocks, each block consisting of interlocking dovetails (12) along with vertical and horizontal mating surfaces (11, 15, 16, 17). The main block has two stabilizing holes (14) running at a vertical axis through the center.  Steel reinforcement rods or square tubes are loosely inserted into these stabilizing holes (14) at predetermined intervals. Corner blocks (26) are employed to connect the walls at right angles and are used in conjunction with short blocks (28) to stagger the vertical joints from course to course. The predetermined tolerances between the masonry components and the loosely placed rods or tubes permit the wall to have a fluid property. Forces such as settling, hydrostatic pressure and seismic disturbances are then automatically absorbed and systematically distributed across the entire wall. When all of the masonry components reach the end of their tolerance, the wall locks up as a solid interconnected mass. The force is then passed on to the stabilizing rods or tubes which now act to stabilize the wall against further movement.

Inventor: BERGER CHRISTIE H
IPC: C09K8/584
Filed: 1998-11-30
Abstract: New anionic surfactants and methods of preparation which are derived from aromatic or substituted aromatic molecules and alkene sulfonic acid. Wherein the aryl compound is alkylated and sulfonated in one-step with an alkene sulfonic acid prior to sulfonic acid neutralization. The methods allow the functional sulfonate group to be attached to the end of the alkyl chain rather than to the aromatic ring thus allowing for selective substituted groups, either branched, linear or alkoxylated or combinations thereof to be placed on the aryl compound prior to sulfonation and alkylation. The invention uses the alkene sulfonic acid produced from thin-film sulfonation of an alpha-olefin to alkylate benzene, mono-substituted aromatic, poly-substituted aromatic, alkylbenzene, alkoxylated benzene, polycyclic aromatic, mono-substituted polycyclic aromatic, poly-substituted polycyclic aromatic, naphthalene, alkylnaphthalene, phenol, alkylphenol, alkoxylated phenol, and alkoxylated alkylphenolalkyl substituted or polysubstituted cyclic or polycyclic compounds to produce the corresponding sulfonic acid having an additional alkyl group derived from the alpha-olefin used during the thin-film sulfonation which is either linear or branched.
