Granted: 2004-06-08
Abstract: A method of generating wall-thickness thinning prediction information where a wall-thickness thinning rate at a given position is estimated using information having a small number of measured points. Simulation of behavior of fluid flowing inside a pipe line is performed based on wall-thickness data of pipes and three-dimensional layout data of the pipe line. Simulated wall-thickness thinned data of the pipes of the pipe line are calculated from changes of the simulated behavior of fluid. The thinning rate prediction data is used to generate a plan for replacing the pipes based on the estimated wall thickness.

Abstract: One node is selected from a plurality of candidates for a bus management node. A bus management node 11 has a register for channels in use REG 1 and a bus capacity register REG2. Before starting the synchronous communication, each node 12 transmits a read-out command to the register for channels in use REG 1 and the register for channels in use REG1 in order to read out their contents for ascertaining the number of the un-used channel and the residual capacity. If there is any un-used channel and any residual bus capacity, the node 12 transmits write commands to these registers REG 1 and REG2 so that the number of the channel to be in use and the capacity of the bus to be in use will be stored in the register for channels in use REG 1 and the bus capacity register REG2. This enables bus management to be achieved easily in a system performing synchronous communication between plural nodes connected to the bus.

Title: Apparatus and method for use in identifying presence of wireless terminals in mobile wireless communications systems
Inventor: LI JUNYI
IPC: H04J3/00
Filed: 2001-12-27
Granted: 2005-10-18
Abstract: An unique arrangement including a so-called timing control order and timing control signals is employed to identify whether wireless terminals are reachable within a base station cell coverage area in a wireless communications system. To this end, detection of a particular wireless terminal being alive and well, and within the cell coverage area associated with a base station is effected by the base station transmitting a timing control order in a timing control time slot reserved for the particular wireless terminal. If the particular wireless terminal receives the timing control order, it transmits a prescribed timing control message at a prescribed time. If the base station does not receive the timing control message, it is an indication that communication with the particular wireless terminal has been lost.

Patent CA-2377617-C (CA)
Title: Provision of media content to telephony callers on-hold
Inventor: SMYTH JOSEPH
IPC: H04M7/00
Filed: 2002-03-20
Granted: 2011-04-05
Abstract: A method of providing media content, such as music and video, to callers on hold involves the generation of the media content locally in the environment of the held caller, rather than the transmission of the content over the network. The local call server of the held caller is signalled when the call has been placed on hold by the server which has placed the call on hold. The caller's server then activates a music-on-hold server (or other media content generator) to provide the media content directly to the caller's telephony terminal. The advantage of this is that the media content is not transmitted across the network, allowing a higher bandwidth to be used locally for the media content without utilising wide area network resources. This results also in the media content being provided in a higher quality format to the caller, avoiding the loss of quality associated with transmitting music using compressive voice codecs over packet-based networks.

Title: Deep bed thickener/clarifiers with enhanced liquid removal
Inventor: BEDELL DANIEL
IPC: B01D21/08
Filed: 2000-07-26
Granted: 2006-09-19
Abstract: The enhanced deliquifying of the compacted bed of deep bed thickener/clarifier is disclosed. Such an apparatus comprises a vessel receiving a slurry of liquid and solid particles suspended in the liquid.      The vessel defines a free settling zone, a hindered settling zone intermediate, an upper clarification zone and a lower compaction zone. A deliquifying member is provided in the vessel extending up between at least two zones for facilitating the upward flow of free liquid from one of the lower zones and the settling of particulates. A rotating rake shaft with pickets are so designed to release the interstitial liquid trapped in a lower zone. The pickets provide pathways for liquid to release generally vertically. The released liquid travels upward to the deliquifying member and on into the clarification zone. The lower zone, freed of the interstitial water, further collapses becoming more concentrated or dense.

Title: Adapter mandrel used in conjunction with premolded high voltage connectors and connector components
Inventor: LUZZI GLENN J
IPC: H02G15/08
Filed: 2002-04-15
Granted: 2007-05-22
Abstract: A mandrel, useful in high voltage cable splicing and termination operations, having a tapered surface and longitudinal ribs for assembly onto a high-voltage cable to be connected to a premolded or extruded high-voltage component. As the premolded high-voltage component is passed over the mandrel, the mandrel expands the internal cavity of the high-voltage component and may further reduce the loss of lubrication within the internal cavity of the high-voltage component thereby allowing for the high voltage component to be easily installed onto the high--voltage cable. After the high voltage component passes over the apparatus, the high-voltage component may return to a lesser-expanded shape providing a snug fit around the cable member. The high-voltage component may then compress around the cable, with a uniform layer of lubricant remaining in between interior cavity of the high-voltage component and the outer layer of the cable.
