Patent number: 9483737Abstract: A method of identifying an event associated with consumption of a utility comprising the steps of generating a utility consumption profile from utility consumption data, the utility consumption data comprising a plurality of utility consumption values measured at a corresponding plurality of measurement points, detecting a plurality of events within the utility consumption profile, grouping the plurality of events using a clustering process to produce a probability density map, comparing the probability density map to a stored profile of events of a particular type, and identifying the group of events as events of the particular type when the probability density map corresponds to the stored profile of events of the particular type, wherein the probability density map is compared to a stored profile of an event which is a probability density map.Type: GrantFiled: May 18, 2012Date of Patent: November 1, 2016Assignee: Onzo LimitedInventor: Jose Manuel Sanchez Loureda

Patent number: 8843332Abstract: A method and apparatus for carrying out noise reduction in data regarding parameter values including the steps of making a series of measurements of parameter values at times separated by predetermined time intervals, forming a plurality of successive measurements into an array of measurements, performing n successive wavelet transforms on the array of measurements to produce an array of coefficients, comparing the values of the array of coefficients to a threshold value and, selectively changing the values of the coefficients based on their relationship to the threshold, to produce an array of filtered coefficients, and performing n successive inverse wavelet transforms on the array of filtered coefficients to produce an array of filtered measurements.Type: GrantFiled: November 12, 2010Date of Patent: September 23, 2014Assignee: Onzo LimitedInventors: Jose Manuel Sanchez Loureda, Adam Richard Westbrooke, Clarke Brunt

Publication number: 20130067182Abstract: A data processing method includes storing data as segments. Data requiring processing is identified. Related data segments are identified and copied to storage in an analysis module. The module reviews the data, identifies required analysis tasks and stores the identified tasks in task storage in the module. The module reviews the tasks to identify required data. The module identifies any required data not stored in the module, and required data is copied to the module. The analysis module executes required task. The module removes executed tasks and updates the data in module storage based on the analysis output. The module reviews data in module storage to identify what analysis must be carried out on the identified data. When an analysis tasks stops, the data store is updated based on the updated module data. The data store comprises storage media and the analysis modules are executed in random access memory.Type: ApplicationFiled: September 7, 2012Publication date: March 14, 2013Applicant: ONZO LimitedInventor: Adam Richard Westbrooke

Publication number: 20100318306Abstract: Apparatus for monitoring the voltage of electricity supplied on a cable (121) are described. The apparatus includes a sense electrode housed in an electrically-insulative housing to form a capacitive coupling (127) between the sense electrode and the cable. The housing may be of the clamp-on type. A sense capacitor (128) of known capacitance is included, which is electrically coupled to the sense electrode and a local ground. Suitable voltage measurement circuitry (126) is connected to the sense capacitor and is responsive to voltage produced across the sense capacitor to provide an output signal representative of the voltage on the cable. The measured voltage waveform can be filtered to give the fundamental of the supply voltage, which can eliminate or reduce the effects of changes in capacitance within one cycle. A secondary capacitive (130) coupling can be formed with a related neutral wire (122) to improve stability of the voltage waveform measurement.Type: ApplicationFiled: May 23, 2008Publication date: December 16, 2010Applicant: Onzo LimitedInventors: Neil MacLachlan Tierney, Benjamin John Pirt, Matthew Emmanuel Milton Storkey, Andrew Nicholas Dames, Neil Alexander Rosewell
