| 20110006756 | POWER MEASUREMENT SYSTEM, METHOD AND/OR UNITS - The invention provides a system ( | 01-13-2011 |
| 20110004421 | METHOD OF INFERENCE OF APPLIANCE USAGE. 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 |
| 20100199781 | Gas Metering - A gas meter comprises a conduit ( | 08-12-2010 |
| 20100109643 | Current Sensor - The present invention is a current sensor architecture using a planar coils in close proximity to a current conductor to detect the rate of change of current in the conductor (and hence, by using an integrator, to recover the AC current). The current sensor is optimised to reject uniform external magnetic fields, gradient external magnetic fields, and fields from one or more conductor assemblies in fixed locations in close proximity to the current sensor, such as might be found in a polyphase electric meter with multiple current sensors. | 05-06-2010 |
