Date Oct. 30, 1997An energy meter for measuring parameters of fuel gas. The meter has a gas inlet and outlet and a central tube along which the gas flows from inlet to outlet. Ultra-sound transducers and a control form a system whereby the speed of ultra-sound signals traveling through the gas between the transducers is measured and used in the control to calculate the volume of gas which is passed through the meter. The ultra-sound signals pass through apertures in the walls of chambers containing the transducers. Another ultra-sound transducer in the chamber which is connected to the control acts as an emitter and receiver of ultra-sound signals reflected by reflectors. These signals travel through the fuel gas in the chamber and their attenuation is observed and measured by the control when they are received by the transducer. The measured attenuation is used to derive the calorific value and/or Wobbe index of the gas. The control uses the volume of gas and the calorific value and/or Wobbe index to derive the amount of energy in the gas.

Title: Data classification apparatus and method thereof
IPC: G06K9/62
Filed: 1998-11-09
Abstract: The data classification apparatus and method is adapted to high-dimensional classification problems and provide a universal measure of confidence that is valid under the iid assumption. The method employs the assignment of strangeness values to classification sets constructed using classification training examples and an unclassified example. The strangeness values of p-values are compared to identify the classification set containing the most likely potential classification for the unclassified example. The measure of confidence is then computed on the basis of the strangeness value of the classification set containing the second most likely potential classification.

Abstract: A method for working a concrete surface uses a water jet ejected from a nozzle of a nozzle holder. The nozzle holder reciprocates in cutting sweeps and moves together with a working apparatus in steps between the cutting sweeps. The water jet is directed in directions of the sweeps, and at the end of each sweep, the nozzle holder is swung into a new angle of attack for a subsequent cutting sweep. At the end of a cutting sweep, the nozzle holder begins to swing backwards simultaneously as its linear velocity increases to permit the target area to remain substantially unchanged at the start of the stepping of the working apparatus so that the water jet makes a cut forwardly in the stepping direction. The stepping and change of angle of attack are completed simultaneously immediately prior to the commencement of a subsequent cutting sweep.
