IPC: G06Q30/00
Filed: 2001-04-20
Abstract: Computerized method and system for identifying repeatedly malfunctioning equipment and root causes therefor are provided. The method allows to provide a database (e.g., 220) comprising detailed equipment data including data indicative of historical equipment malfunctions in a plurality of pieces of equipment. The equipment data includes a unique equipment identifier for uniquely relating each malfunction to respective equipment. The method further allows to analyze the data base for a selected time window to review equipment malfunctions logged in the data-base and resulting in servicing activities over that time window. An equipment malfunction threshold for the number of malfunctions occurring during a predetermining period of time is established. The database is configured to automatically issue a report identifying any respective equipment as a repeatedly-malfunctioning-equipment whenever the number of equipment malfunctions resulting in servicing activities over that time window exceeds the equipment malfunction threshold. An input/output device (e.g., 226) is provided to communicate with said database to receive the report from the database. A work order for the repeatedly malfunctioning-equipment is instantiated, wherein the order is configured to remain open at least until service personnel logs comment data into the work order indicative of possible root causes for the repeatedly malfunctioning equipment.

Patent CA-2402018-A1 (CA)
Title: High-speed data processing using internal processor memory space
Inventor: MONROE DONALD W
IPC: H04L12/56
Filed: 2001-03-02
Abstract: Significant performance improvements can be realized in data processing systems by confining the operation of a processor within its internal register file so as to reduce the instruction count executed by the processor. Data, which is sufficiently small enough to fit within the internal register file, can be transferred into the internal register file, and execution results can be removed therefrom, using direct memory accesses that are independent of the processor, thus enabling the processor to avoid execution of load and store instructions to manipulate externally stored data. Further, the data and execution results of the processing activity are also accessed and manipulated by the processor entirely within the internal register file. The reduction in instruction count, coupled with the standardization of multiple processors and their instructions sets, enables the realization of a highly scaleable, high-performing symmetrical multi-processing system at manageable complexity and cost levels.

Patent CA-2414091-A1 (CA)
Inventor: SALMINEN PEKKA
IPC: B28D1/26
Filed: 2001-06-18
Abstract: The invention relates to a method of opening joints of drilling components attached to a rock drill, and to a rock drill which enabling this. According to the idea of the invention, in striking compression stress, which proceeds towards a drill bit (10), is generated in the drilling equipment (5) by striking with a percussion piston. When the drilling components are struck off, the axial bearing included in the drilling machine does not substantially support the drilling equipment, but the compression stress generated by striking is reflected from the drill bit (10) as stress of the opposite sign and generates the desired tensile stress in the drilling equipment. After striking the threaded joints of the drilling components can be opened easier by rotating the rotating device in the opposite direction.

Title: A phase-locked loop
Inventor: SMITH ALAN
IPC: H04B7/26
Filed: 2001-12-18
Abstract: A phase-locked loop has associated with it a first register set (21) for holding data defining a mode of operation of the phase-locked loop; and a second register set (22) for holding data defining a mode of operation of the phase-locked loop. Switches (27 to 30) are provided for coupling one of the first and second register sets to receive data defining a new mode of operation while the other of the first and second register sets is connected to the phase-locked loop to cause the same to operate in the mode defined by the data in the other register set. The switches are reconfigurable to change the coupling so that the other register set is coupled to receive data defining a further new mode of operation while the one register set is connected to the phase-locked loop to operate in the new mode of operation.  The two register sets allow the phase-locked loop to switch quickly between different operating frequencies.
