Patent CA-2269962-A1 (CA)
Inventor: POOLE DAMIAN MOUNSEY
IPC: B61L1/18
Filed: 1999-04-23
Abstract: In an arrangement for monitoring the resistance between adjacent rail-ends of a section of railway track, the usual insulating end-post between the ends of adjacent rails is a moulded component provided with an embedded conductive mesh or perforated plate situated roughly halfway between the rail-ends. The resistance between each rail-end and the conductive part is monitored to detect any significant decrease in resistance between either rail and the conductive part. When a sufficiently large resistance drop is detected, the normal track signalling circuits associated with the section of line involved are still able to function normally, since the insulation on the other side of the mesh is still unaffected at this stage. Railway personnel are now able to effect a repair to the affected part of the track at their (and the passengers') convenience before the whole end-post fails, disrupting normal service.

Abstract: The invention relates to an administratively optimized calculation of communication bills process and/or system which, with the aid of a flat-rate-calculating computer (1), which is connected to an associated exchange (3) for customer terminals (7), carries out automatic administratively optimized calculation of communication bills. Such automatic administratively optimized calculation of communication bills is both for digitized and also for analogue communication networks, wire-bound, radio-based or laser-assisted, terrestrial or via satellite. Each terminal (7) is connected to a communication meter (8) which is lead-sealed or in other manner protected against manipulation and can be read by means of telemetry or, after the sending of a special meter-reading card, by the customer. The flat-rate-calculating computer (1) processes the information about consumed volumes of information in three ways. First, it compares the current values with the specified process widths and, if process alarm limits have been exceeded, generates a process alarm; it checks the current consumption values for the formation of a possible trend and generates an indicator alarm if there is a trend-wise exceeding of a limit value. It store: the charge information, process behaviour and alarms in a system memory (14) for documentation purposes. At a predetermined time or if there is a special need, it calculates a new flat-rate value which corresponds to the changed communication behaviour of the respective customer or group of customers. For the purpose of control, the flat-rate-calculating computer (1) is connected to an operator terminal (10) with hardcopy printer (11).

Patent CA-2292406-A1 (CA)
Inventor: BEAINI PETER
IPC: E03B7/12
Filed: 1999-12-14
Abstract: Freezing domestic mains have always been a problem for areas where subzero temperatures are experienced. This occurs because of the lack of movements of the water in the mains overnight when there is no domestic water demand. The answer to this problem has always been to either leave the water to run aground or create/install a circulation line. One solution is wasteful and the other is expensive, as massive digging would have to be done.

Title: Method and system for the update of remote data using persistent keys
Inventor: TALBURT JOHN R
IPC: G06F17/30
Filed: 1998-07-21
Abstract: A method and system for the creation, enhancement and update of data on a customer database using data from a central database and persistent keys that are linked to each data structure is disclosed. The persistent keys allow the matching of equivalent data structures between the remote and central databases so that enhancement data from the central database can be overlaid onto the customer database. The persistent keys also make the update of data on the customer database more efficient, since key matching allows the transfer of ply the data that is needed to update the customer database. The central database may physically contain all of the enhancement data, or may use a central database manager to transparently link a group of physically remote databases using the persistent keys. Data may be transferred from the central database to the customer database either in batch mode or in a near real-time mode through a direct table join. The linking feature of the persistent keys further allows the linkage of the customer database and the central database to create a multidimensional database.

Patent CA-2304214-A1 (CA)
Title: Internet telephony call routing engine
Inventor: LOVETTE BRIAN KEITH
IPC: H04L29/06
Filed: 1998-09-16
Abstract: The present invention discloses a centralized routing engine that is able to assist gateways in making routing decisions for calls being placed in an Ip network environment. Types of calls include voice, fax, video, etc. The routing engine provides significant flexibility to the gateways by allowing the gateways to designate preferences that define operational limits or requirements. A source gateway operator may set preferences such as the maximum price that is willing to be paid for a call, the maximum delay that will be tolerated and the maximum autonomous system hop count that will be tolerated. A destination gateway operator is likely only to be concerned with setting price schedules as preferences. Gateway operators may also set "preference criteria", which define the circumstances in which a certain set of preferences is to be applied.      Based on preferences and preference criteria, the routing engine is able to locate destination gateways that are eligible to terminate a voice over telephony IP call. The routing engine provides a prioritized list of eligible destination gateways to the source gateway. The source gateway then works through the prioritized list and attempts to set up the voice over IP telephony call with each eligible destination gateway, until the call is established.
