Patent number: 10862988Abstract: Methods and systems for operating a sensor network are provided. In one example, a server may provide graphical data representing a hierarchical sensor network for displaying at a client device. The server may receive a selection to display sensor data from a first node of the nodes of the hierarchical sensor network and determine, based on the selection, a hierarchical sensor label associated with one or more first sensors of the hierarchical sensor network corresponding to the first node. The server may also receive a plurality of messages including sensor data generated by a plurality of sensors of the hierarchical sensor network from an in-bound real-time message processor, and identify a first set of messages based on the hierarchical sensor label.

Patent number: 8330383Abstract: A method and system for dependently controlling color light sources. The lighting system comprises a drive current controller providing current signals for one or more first groups of light-emitting elements, and a signal derivation module operatively connected to the drive current controller. The signal derivation module is configured to determine and provide current signals for one or more second groups of light-emitting elements, the current signals being based on the current signals provided to the first groups of light-emitting elements. The method comprises the steps of determining one or more first drive currents for driving one or more first groups of light-emitting elements, and determining one or more second drive currents for driving one or more second groups of light-emitting elements, wherein each of the one or more second drive currents is predetermined based on at least one of the one or more first drive currents.Type: GrantFiled: April 23, 2008Date of Patent: December 11, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Kwong Man, Duncan Smith

Patent number: 7866845Abstract: The present invention provides an optical device configured for the creation of an asymmetric illumination beam pattern while additionally mixing the light created by two or more light-emitting elements. The optical device comprises a reflector body which extends between an entrance aperture and an exit aperture, wherein the two or more light emitting elements are positioned relative to the entrance aperture and light is reflected within the reflector body exiting at the exit aperture. The reflector body includes a first pair of walls including symmetric reflective elements and a second pair of walls orthogonal to the first pair of walls, wherein the second pair of walls includes asymmetric reflective elements. The first pair of walls provides a means for mixing the light generated by the two of more light-emitting elements and generating a symmetric beam pattern about a first axis.Type: GrantFiled: March 8, 2007Date of Patent: January 11, 2011Assignee: Koninklijke Philips Electronics N.V.Inventor: Kwong Man

Publication number: 20100259182Abstract: The light source comprises one or more first light-emitting elements for generating light having a first wavelength range and one or more second light-emitting elements for generating light having a second wavelength range. The first light-emitting elements and second light-emitting elements are responsive to separate control signals provided thereto. A control system receives a signal representative of the operating temperature from one or more sensing devices and determines first and second control signals based on the desired colour of light and the operating temperature. The light emitted by the first and second light-emitting elements as a result of the received first and second control signals can be blended to substantially obtain the desired colour of light. The desired colour of light generated can thus be substantially independent of junction temperature induced changes in the operating characteristics of the light-emitting elements.Type: ApplicationFiled: February 9, 2007Publication date: October 14, 2010Applicant: TIR TECHNOLOGY LPInventors: Kwong MAN, Ian ASHDOWN
