Patent CA-2283239-A1 (CA)
Inventor: JONES MARTIN KELLY
IPC: G06Q10/08
Filed: 1998-03-09
Abstract: An advance notification system (10) notifies users of the impending arrival of a vehicle, for example, an overnight package delivery vehicle, at a particular vehicle stop. The system generally includes an on-board vehicle control unit VCU (12) for each vehicle and a base state control unit BSCU (14) for sending messages to user computers (29) in order to inform the users when the vehicle resides at a certain predefined time period, distance, prior stop, location point from the vehicle stop. Moreover, the BSCU, a computer network, and software located on a user computer may be combined in a plurality of configurations for communicating a message of the impending arrival of a particular vehicle before it arrives. Each vehicle control unit VCU (12) includes a microprocessor controller (16). The VCU sends vehicle location and/or stop information to the BSCU. The BSCU compares the vehicle route stop list with route management software, then determines when to send an impending arrival message by the system operator.

Title: Automatic golf ball washer caddy
Inventor: BOGLE EVARD ANTHONY
IPC: A63B47/04
Filed: 1999-09-14
Abstract: This invention relates to a more improved Golf Ball Cleaner, ball storage with accessories such as a clipboard, area for storing tees, pencil, liquid solution and a towel. This mention is an Automatic Golf Ball Washer Caddy. This Golf Ball Washer can be used on a stationary surface, attached to a golf cart, golf bag of a power driven cart. With the aid of an electronic timer and/or a conventional switch, the primary objective of this invention is to provide an improved ball cleaner that can be used anywhere or anytime. The ball is therefore placed in the receiving chamber by means of a cradle. This chamber has brushes strategically placed as to promote effective ball rotation. The cleaning action is realized by the ball travelling upward and downward by a motor, shaft and a spring. The ball is rubbed against the imbedded brushes causing a leaning action. This cleaning process is aided with a battery as a power supply, attached to a motor, turning a special design shaft connected to an upright shaft striking the ball upwards and a spring that forces the ball downwards. Through the illustrations and drawings you will be able to understand this invention where also the claims will be made.

Title: Methods and apparatus for diagnosing and remediating reading disorders
Inventor: LAWTON TERI A
IPC: G16H20/70
Filed: 1998-04-07
Abstract: Reading disorders are diagnosed and remediated in a subject by respectively measuring and improving contrast sensitivity for motion discrimination of the subject. A background (130) is displayed on a monitor (104) with a contrast and a spatial frequency. A test window (134) is superimposed over the background (130) and includes a test pattern (132) with a contrast and a spatial frequency. The contrasts and the spatial frequencies are within respective ranges which simulate the visual cortical movement system of the subject. The test pattern (132) is then moved within the test window (134). The subject provides a signal indicative of the direction of the subject believes the test pattern (132) moved. In response to this signal, the contrast of the test pattern (132), the spatial frequency of the background (130), or the spatial frequency of the test pattern (132) is modified, either by increasing or decreasing its respective value. This process is then repeated a number of times, cycling through predetermined combinations of test patterns (132) and backgrounds (130). Contrast sensitivity may be measured to determine whether a child is dyslexic. Repeated stimulation by the methods and apparatus of the invention improves contrast sensitivity, thereby remediating dyslexia and improving reading ability.

Title: An on-line incentive system
Inventor: ROWNEY KEVIN T
IPC: G06Q30/00
Filed: 1999-10-05
Abstract: An on-line incentive system provides a means for a consumer to enter an earning activity to earn value from the merchant. If the consumer qualifies, value, in the form of private label currency, is transferred from the merchant to the consumer without re-directing the consumer away from the merchant's web site. The merchant requests authorization to a clearinghouse site to transfer value from the merchant to the consumer via a value transfer network.     The request is dispatched, via the Internet, from the merchant site to the clearinghouse site. If the value transfer is unsuccessful, then the incentive management system enters asynchronous retransmission mode, wherein the value transfer is periodically initiated from the merchant location to the clearinghouse location. At the clearinghouse site, authorization for the value transfer is determined, and a response message that indicates a status for the authorization is dispatched to the merchant. Thereafter, a response is sent to the consumer that indicates the status of the authorization request.

Patent CA-2312444-A1 (CA)
Inventor: TING EDISON L
IPC: G06F12/121
Filed: 2000-06-20
Abstract: The invention concerns generally memory management and in particular a data buffer memory management method and system for increasing the effectiveness and efficiency of buffer replacement selection. Hierarchical Victim Selection (HVS) identifies hot buffer pages, warm buffer pages and cold buffer pages through weights, reference counts, reassignment of levels and ageing of levels, and then explicitly avoids victimizing hot pages while favoring cold pages in the hierarchy. Unlike LRU, pages in the system are identified by both a static manner (through weights) and in a dynamic manner (through reference counts, reassignment of levels and ageing of levels). HVS provides higher concurrency by allowing pages to be victimized from different levels simultaneously. Unlike other approaches, Hierarchical Victim Selection provides the infrastructure for page cleaners to ensure that the next candidate victims will be clean pages by segregating dirty pages in hierarchical levels having multiple separate lists so that the dirty pages may be cleaned asynchronously.
