Publication number: 20160032893Abstract: A computer-implemented method of operating a wind turbine park including operating wind turbines includes recording a plurality of sound pressure measurements of the wind turbine park, thereby generating a sound recording. The method also includes calculating values for a plurality of acoustic features associated with the sound recording. The method further includes determining a relationship between the calculated values for the plurality of acoustic features and modeled acoustic features values resident within a probabilistic auditory model of the wind turbine park. The method also includes distinguishing a first contribution to the sound recording originating from the at least one operating wind turbine from a second contribution to the sound recording originating from non-wind turbine sources based on the determined relationship.Type: ApplicationFiled: July 31, 2014Publication date: February 4, 2016Inventors: Andreas Herrig, Benoit Philippe Petitjean, Sara Simonne Louisa Delport, Nathan Charles Schneider

Publication number: 20150179938Abstract: The present invention provides templating methods for replicating patterned metal films from a template substrate such as for use in plasmonic devices and metamaterials. Advantageously, the template substrate is reusable and can provide plural copies of the structure of the template substrate. Because high-quality substrates that are inherently smooth and flat are available, patterned metal films in accordance with the present invention can advantageously provide surfaces that replicate the surface characteristics of the template substrate both in the patterned regions and in the unpatterned regions.Type: ApplicationFiled: December 22, 2014Publication date: June 25, 2015Inventors: David J. Norris, Sang Eon Han, Prashant Nagpal, Aditya Bhan, Nathan Charles Lindquist, Sang-Huyn Oh

Publication number: 20150091134Abstract: A method of depositing a material on a substrate using an atomic layer deposition process, wherein the deposition process comprises a first deposition step, a second deposition step subsequent to the first deposition step, and a delay of at least one minute between the first deposition step and the second deposition step. Each deposition step comprises a plurality of deposition cycles. The delay is introduced to the deposition process by prolonging a period of time for which a purge gas is supplied to a process chamber housing the substrate at the end of a selected one of the deposition cycles.Type: ApplicationFiled: April 3, 2013Publication date: April 2, 2015Applicant: Dyson Technology LimitedInventors: Gehan Anjil Joseph Amaratunga, Youngjin Choi, Sai Giridhar Shivareddy, Nathan Charles Brown, Charles Anthony Neild Collis

Publication number: 20100006122Abstract: An electrolytic cell includes an electrode in a chamber including an electrolyte and an electrical power supply arranged to supply electrical energy to the electrode. A current sensor detects electrical current in the cell. A reservoir of a metal salt solution is provided. A controller is arranged to supply metal salt solution from the reservoir to the chamber of the cell in dependence on the current detected at the sensor. This permits the conductivity of the electrolyte to be brought up to required levels quickly, independently of dynamic cell conditions. Previously, metal salt was added gradually to the electrolyte. This was time-consuming and produced inconsistent results.Type: ApplicationFiled: April 2, 2007Publication date: January 14, 2010Inventors: Nathan Charles Brown, Chaoying Fang

Publication number: 20090272654Abstract: An electrolytic cell generates hydrogen peroxide and includes a reservoir for storing hydrogen peroxide generated by the cell. A controller is arranged to activate the cell and introduce stored hydrogen peroxide from the reservoir to the cell. This permits the concentration of a store of hydrogen peroxide to be refreshed as required, by introducing the stored hydrogen peroxide as the electrolyte in the cell. This counteracts the natural decay of the stored hydrogen peroxide. The pH of the hydrogen peroxide is controlled so that it is below a predetermined value. It has been found that hydrogen peroxide having a low pH, close to neutral, decays much more slowly than hydrogen peroxide having a more strongly alkaline pH.Type: ApplicationFiled: April 2, 2007Publication date: November 5, 2009Applicant: Dyson Technology LimitedInventors: Nathan Charles Brown, Chaoying Fang

The housing contains a reservoir for storing liquid, an electrolytic cell for receiving liquid from the reservoir and increasing the level of oxidative properties in the liquid, and a pump for circulating fluid between the reservoir and the electrolytic cell so that liquid having enhanced oxidative properties in dispensed from the nozzle. In the preferred embodiment, the electrolytic cell generates hydrogen peroxide from water introduced to the reservoir by the user so that a sterilising solution of hydrogen peroxide is dispensed from the nozzle.Type: ApplicationFiled: February 10, 2009Publication date: August 27, 2009Applicant: Dyson Technology LimitedInventors: Kevin John Simmonds, Matthew Cookson, Damian Henri Lee, Nathan Charles Brown

Publication number: 20090165823Abstract: An electrolytic cell for producing hydrogen peroxide includes an anode, a cathode and an intermediate membrane. The anode is associated with a first electrolyte and the cathode is associated with a second electrolyte. The use of two electrolytes associated with the respective electrodes permits the user to select the most suitable salt solutions for each electrode and so avoid production of gases and by-products unsuitable for a domestic environment. Thus, the electrolytic cell is suitable for use in an automatic dishwasher.Type: ApplicationFiled: April 2, 2007Publication date: July 2, 2009Applicant: DYSON TECHNOLOGY LIMITEDInventors: Nathan Charles Brown, Chaoying Fang

Publication number: 20020143649Abstract: Each digital photo taken by a participating photographer is assigned a unique number which is given to the subject of the photo. The photos are then uploaded to a website where they are stored on a server and made accessible to the subjects of the photos via the internet. The photos preferably are virtually branded with a watermark or proof mark, and are also permanently associated with an ornamental border. Knowing his photo number, the subject can view his photograph online, and e-mail it to others, who can order high quality versions of selected photos online. The web site refers such orders to one or more finishing laboratories that prepare photos and mail them directly to the customers. The web site secures payment for this service by a credit card charge, and then distributes those fees down a marketing hierarchy, ultimately to the photographers, according to a protocol agreed to in advance by all participants.Type: ApplicationFiled: August 10, 2001Publication date: October 3, 2002Inventor: Nathan Charles Wise
