Abstract: A method of cataloguing a data structure employs the formation of a catalogue data structure which is used to associate data items transformed from data elements present within the data collection with storage addresses of the original transformed data elements. This catalogue data structure may be sorted to facilitate searching through same to detect the presence of search patterns. Such searches may be completed through the formation of a plurality of search queries from a received search pattern sequence where the results of running these search queries may then be subsequently considered in conjunction with a search pattern sequence detection process.

Abstract: The present invention is directed to network monitoring systems. Test probes available for use in connection with network monitoring are registered. As part of the registration of test probes, information related to the type of device implemented by each test probe is also collected. Information related to the network or subnetwork with which each device is associated may also be collected. The collected information may therefore comprise system topology discovery. In addition, the collected information may be used to select distributions of device types in order to implement particular test schemes or protocols.

Abstract: The present invention relates to a method of cataloguing a data structure and also preferably a method of searching through such as data structure to detect the presence of search patterns within the data structure. The catalogusing method of the present invention employs the formation of a catalogue data structure which is used to associate data items (transformed from data elements present within the data collection) with storage addresses. This catalogue data structure may be sorted to facilitate searching through same. Such searches may be completed through the formation of a plurality of search quries from a received search pattern sequence where the results of running these search queries may then be subsequently considered in conjunction with a search pattern sequence detection process.

Abstract: Rotary cutting tools for cutting various types of sheet material are known. However, when cutting non-ferrous materials, damage known as fluttering is caused to both surfaces of the sheet material being cut. The requirement for the cutting of larger and larger sheets of material for safety critical applications such as aircraft wings has made fluttering unacceptable. Furthermore, scrapping sheets of material which exhibit fluttering is extremely expensive. Fluttering occurs as a result of excess pressure being placed on a workpiece edge as it is being cut. A rotary cutting tool (10) for a power tool is disclosed in which the cutting tool comprises body means (12) having a first flute (20, 30), a substantially planar first cutting surface (22, 32) and a first cutting edge (24, 34) formed on said first cutting surface; and wherein said first cutting edge (24, 34) is formed at a first angle to a longitudinal axis of the cutting tool. This cutting tool addresses the problems associated with fluttering.

Abstract: A modular elevator system is disclosed incorporating a wiring and control module which is attached to the elevator car. One of the modules includes a floor selection device and display panel accessible from within the elevator car and a proximity sensor accessible from the outside of the elevator car. The other modules are attached to the elevator shaft and disposed at aligned and vertically spaced locations corresponding to each floor. The modules interact to control door operation and elevator car position.
