Virtual reality modelling

A model of a geometrical object comprising: bits in a first data structure encoded to identify a first set of elements from a collection of representations of geometrical shapes for a collection of elements and to represent positions of the elements by means of integer co-ordinates in a first system of co-ordinates; bits in a second data structure encoded to identify a second set of elements from said collection and to represent positions of the elements by means of integer co-ordinates in a second system of co-ordinates; bits in a third data structure encoded to represent a spatial transformation of the second system of co-ordinates relatively to the first system of co-ordinates. Thereby it is possible to create a very compact representation of a model of a geometrical object. The model-prima facia-seems to be constrained very hard, but is in fact a very flexible and easy to access model.

Client-based web server application verification and testing system

A client-based web server application verification and testing system that requires no technical training, yet provides effective and efficient automated testing. The invention facilitates the rapid generation of test cases for a web site, and the automated execution of those test cases via distributed computing. The transitions through a web site are mapped onto a tree control to exploit user familiarity with a dual pane graphical interface and the drag / drop operation on tree controls. The tree is populated primarily by an autonomous spider exploring the site. Complex sequences requiring form inputs are added by recording sample sequences and then allowing the user to prune from all possible permutations of those samples. The export and import of form input data to a spreadsheet provides additional flexibility. Both the exploration and validation tasks may be distributed to a network of computers.

Musical tone generating apparatus and method for generating musical tone on the basis of detection of pitch of input vibration signal

A vibration signal (e.g. a human voice) is generated at a desired pitch corresponding to a tone pitch of a musical tone desired to be generated, and is input via a microphone. The pitch of the input vibration signal and an amplitude (volume) level thereof are detected. When an amplitude level equal to or greater than a predetermined threshold level has been detected but the pitch has not been detected yet, an instruction of generation of a noise tone is issued thereby to generate the noise tone. Thereafter, when a certain pitch is detected, a musical tone is generated at a pitch determined according to the detected pitch. In this way, a noise tone is generated during a delay in pitch detection, and a delay in response at the start of sounding is absorbed.

The address search information is stored in fast memory in a tree search format and the set of possible next destinations are stored as forwarding option data in slower memory at addresses derived algorithmically from the tree search address information. Internet data packets are received and data therein is compared to determine the best match address in the fast memory to the set of possible best next destinations. The multiple accesses necessary to determine the best match address are confined to high speed memory. An algorithm receives option data from an Internet packet and option threshold data from the best match address of the high speed memory and determines which address of the slower memory has the desired forwarding data using one access.
