Patent number: 8975779Abstract: The present invention relates to a load management controller for a household electrical installation comprising a pair of electricity supplies, a grid supply and a micro-generator supply, providing electricity to a plurality if sub-circuits. The household electrical installation has means to monitor the amount of electricity being supplied by the micro-generator supply and the amount of electricity being consumed in the household. The load management controller has means to access and use that information to control the supply of electricity to an energy storage sub-circuit to route surplus electricity supplied by the micro-generator to the energy storage sub-circuit. Furthermore, the load management controller can communicate with a remote electricity supplier to control the loads in the household to achieve better grid management and efficiency.Type: GrantFiled: April 17, 2008Date of Patent: March 10, 2015Inventors: Timothy Patrick Cooper, Colin David Harris, Thomas Laurence Bean

Patent number: 8787620Abstract: A nuclear imaging system includes a crystal identification system which receives a flood image which includes a plurality of peaks, each peak responsive to radiation detected by a corresponding scintillator crystal. A crystal identification processor partitions the flood image into a plurality of candidate regions with a watershed segmentator implementing a watershed algorithm. The candidate regions are linked in an adjacency graph, and then classified as background or relevant, where relevant regions contain a peak within the watershed lines. The regions are then assigned to a crystal according to an objective function and an assignability score. A calibration processor maps the peaks to a rectangular grid.Type: GrantFiled: July 31, 2013Date of Patent: July 22, 2014Assignee: Koninklijke Philps N.V.Inventors: Thomas Laurence, Sharon X.

Patent number: 8750569Abstract: A nuclear imaging system (10) includes a crystal identification system (40) which receives a flood image (30) which includes a plurality of peaks, each peak responsive to radiation detected by a corresponding scintillator crystal. A crystal identification processor (42) partitions the flood image (30) into a plurality of regions (56), each region being masked to correspond to one of an array of nuclear detectors. A model image (62) is generated in which the at least one Gaussian models represents the identified peaks. Misidentified peaks in the model image (62) in which locations of the peaks in the flood image (30) differ from the corresponding scintillator crystal are determined and the locations of the misidentified peaks in the flood image (30) are corrected. A calibration processor (43) corrects geometric distortions in acquired projection data according to the corrected peaks.Type: GrantFiled: April 27, 2011Date of Patent: June 10, 2014Assignee: Koninklijke Philips N.V.Inventors: Thomas Laurence, Sharon X.

Patent number: 7633057Abstract: A scintillator (18) includes radioactive elements which emit radiation of a characteristic energy, such as lutetium176, which emits 202 keV and 307 keV ?-rays. The scintillators have light output levels that vary and photomultiplier tubes that respond to the light scintillations tend to drift. When a scanner (10) is not generating diagnostic images, the photomultiplier tubes detect scintillations from the lutetium 176 radiation. A self-calibration processor (40) adjusts the gain for each photomultiplier tube such that its output peak corresponds to 202 keV or 307 keV and adjusts a scaling factor for PMT outputs corresponding to each scintillator such that the output peaks have a common amplitude.Type: GrantFiled: September 15, 2006Date of Patent: December 15, 2009Assignee: Koninklijke Philips Electronics N.V.Inventors: Steven Cooke, Thomas Laurence
