DATA PROCESSING APPARATUS AND/OR COMPUTER SOFTWARE - A method of inference of appliance usage from a point measurement on a supply line, said supply line being common to multiple appliances and/or components of appliances comprises the steps of: obtaining data from said measurement point; sampling power and reactive power at intervals substantially throughout periods of operation of said appliances or components of appliances corresponding to appliances or components of appliances being in ON and/or OFF modes of use; identifying characteristics of events by assessing power and reactive power change during an event; and by assessing one or more additional characteristics derivable from said power and reactive power to characterise an appliance; grouping events and/or cycles of events into clusters of similar characteristics; and inferring appliance usage based on said grouping. | 01-06-2011 |
20120266688 | Gas Metering - A gas meter comprises a conduit for passage of a gas flow and an ionizer to ionize the gas flow. A modulating electrode structure downstream of the ionizer modulates the ion distribution in the ionized gas flow. A first and a second electrode structure downstream of the modulating electrode structure detect the ion distribution in the ionized gas flow. The modulating electrode structure and the detecting electrode structure can generate an electrical field parallel to the direction of the gas flow. The modulating electrode structure and the detecting electrode structures can each have apertures defined therein for passage of the gas flow. The modulating electrode structure can capture ions of one polarity to generate an ionized gas flow comprising a majority of ions of the opposite polarity. Movement of the ionized gas flow generates a current indicative of the ion distribution between the electrode and the charge source. | 10-25-2012 |
