Patent CA-2332199-A1 (CA)
Inventor: AGAR ROBERT S
IPC: A47B96/14
Filed: 2001-01-25
Abstract: A shelving standard is fabricated from a single plate with portions of the plate folded back on themselves, preferably utilizing roll forming operations. This allows bores formed in the plate before roll forming to be aligned in pairs as through holes when portions of the plate are folded over on themselves. By forming one bore of a pair larger than another, the bore pair becomes a countersunk hole. Such a shelving standard may be screwed to a stud which has a gap therein so that a line of slots in the standard is aligned with the gap.  The stud also has a transverse through hole supporting a cross-member. Wall panels are provided with clips which rest on the cross-member so that wall panels may be mounted without being screwed to the stud.

Title: System and method for correcting spelling errors in search queries
Inventor: BOWMAN DWAYNE EDWARD
IPC: G06F17/30
Filed: 1999-07-08
Abstract: A search engine uses correlations between search terms to correct misspelled  terms within search queries. The correlations are based at least in-part on historical query submissions to the search engine. Preferably, the correlations reflect the frequencies with which the search terms have historically appeared together within the same query, and are stored within a correlation table (50) using related terms lists (62). In one embodiment, a correlation table (50) is generated periodically from the M (e.g. 10) most recent days of entries in a query log (36), and thus reflects the current preferences of users. In operation, when a query that includes both matching  and non-matching search terms is submitted to the search engine, a spelling correction process (48) accesses the correlation table (50) to generate a li st of terms that are deemed to be related to the matching term(s). The spelling s of these related terms are then compared to the spelling of each non-matchin g term using a spelling comparison function that compares two character string s and generates a similarity score. If a suitable replacement is found for a given non-matching term, the non-matching term is replaced with the similar related term. The modified query is then used to perform the search, and the  user is notified of themodification(s) made to the query. In the disclosed embodiment, the search engine is used on the Web site of an online merchant to assist users in locating book titles, music titles, and other types of products.

Title: Systeme d'exploitation pour communications
Inventor: SNELGROVE WILLIAM MARTIN
IPC: H04Q3/00
Filed: 1999-09-24
Abstract: Cette invention qui se rapporte, d'une manière générale, aux télécommunications, porte, plus précisément, sur un système d'exploitation amélioré ainsi que sur le dispositif correspondant, en rapport avec des réseaux de télécommunications. Actuellement, la majorité des services de télécommunications est assurée sur le réseau téléphonique public commuté et sur l'Internet. Les systèmes de téléphonie existant connaissent un certain nombre de problèmes, complexité du système, accès limité et mise en oeuvre des services sur un matériel fixe, ce qui retarde longuement l'apparition sur le marché de nouveaux produits. Les applications d'Internet ne sont pas à même de garantir une certaine qualité de service dans la transmission. Ces systèmes manquent de souplesse et d'efficacité, ce qui limite leur capacité à assurer de nouveaux services. L'invention porte, de ce fait, sur un système d'exploitation utilisable sur divers réseaux de télécommunications, système réparti et en temps réel. Elle concerne également des techniques de mise en oeuvre d'une exécution synchronisée, de résistance aux pannes et de gestion de charge. L'utilisation de ce nouveau système d'exploitation avec des réseaux existants permet d'offrir de nouveaux services.

Title: System and method for stocking products with an electronic price label system
Inventor: GOODWIN JOHN C III
IPC: G06Q30/00
Filed: 2001-06-13
Abstract: A system and method are disclosed for stocking products with an electronic price label (EPL) system. An EPL in the system may be actuated, either by a store employee or a customer, when the shelf stock of the corresponding merchandise item has been depleted. The EPL then displays an icon to indicate that the item is out of stock. A stock management computer program determines when an EPL has been actuated, and sends information concerning the out-of stock product to a visual display in the store's stock room. Store personnel can actuate the stock room visual display to alert the system that appropriate quantities of the product have been pulled from a stock room bin. The applicable EPL then may be actuated a second time, by store personnel, when the store shelves have been restocked with the item.
