Patent number: 8961179Abstract: An apparatus and method for mineralising demineralised and hypo-mineralised biological material such as tooth or bone. The apparatus has a probe electrode for receiving a mineralisation agent and a counter electrode. It is also provided with a controller to control the electrical signal provided to the probe such that the extent of mineralisation of the biological material is controlled by modulating or changing the electrical signal provided by the probe based upon the measured output of the circuit formed from the probe, counter electrode and biological material. The electrical output provides a measure of the extent of mineralisation of the biological material which is compared with data from a reference technique which gives 3D structural information on an area of interest in the biological material.Type: GrantFiled: August 18, 2009Date of Patent: February 24, 2015Assignees: The University of Dundee, The University of Abertay, Dundee, The University Court of the University of St. AndrewsInventors: Christopher Longbottom, Joseph Crayston, Nigel Berry Pitts, Dmitri Grinev, Iain Young

Publication number: 20120287159Abstract: A method of generating a view of a computer-generated environment using a location in a real-world environment, comprising receiving real-time data regarding the location of a device in the real-world environment; mapping the real-time data regarding the device into a virtual camera within a directly-correlating volume of space in the computer-generated environment; updating the virtual camera location using the real-time data, such that the virtual camera is assigned a location in the computer-generated environment which corresponds to the location of the device in the real-world environment; and using the virtual camera to generate a view of the computer-generated environment from the assigned location in the computer-generated environment.Type: ApplicationFiled: July 20, 2012Publication date: November 15, 2012Applicant: University Court of the University of Abertay DundeeInventor: Matthew David BETT

Patent number: 6692632Abstract: A method of reacting chemicals comprising the exposure of the reactants to ultrasound and electrochemical energies in the presence of a metal or metal salt and hydrogen peroxide. HO* radicals are efficiently formed and react with a carbon-based reactant to form a carbon radical which then reacts with other reactants or may dimerize. The invention regenerates the metal ions and may be performed using no special facilities. Increased product yield was achieved for a number of hydroxylation reactions.Type: GrantFiled: June 25, 2002Date of Patent: February 17, 2004Assignee: University of Abertay DundeeInventors: David Bremner, Arthur Ernest Burgess
