Patent number: 8786114Abstract: A power supply system comprises an internal combustion engine (20) having a pair of opposed pistons (28, 30) and cylinder (32) within which the pistons move in use, the pistons (28, 30) and cylinder together forming a combustion chamber. The pair of opposed pistons (28, 30) and the cylinder (32) are each arranged to rotate, in use, about a common axis of rotation A with respect to an associated electric generator arrangement (22) so as to generate an electric output. The pair of opposed pistons (28, 30) are also arranged to together form a mass-elastic system that is capable of resonance and further arranged such that combustion in the combustion chamber causes the pistons (28, 30) to oscillate relative to each other about the common rotational axis (A).Type: GrantFiled: April 30, 2010Date of Patent: July 22, 2014Assignee: University of SussexInventor: Julian Francis Dunne

Publication number: 20100162185Abstract: A system for optimising electronic circuits to be designed has two parts or phases, a training phase 10 in which optimisation scenarios for selected electronic circuits are derived using an evolutionary algorithm, and an operation phase 11, in which the derived optimisation scenarios are used to optimise new electronic circuits to be designed. The training phase 10 uses an evolutionary algorithm to produce a specialised and relatively fast optimisation scenario for each of a plurality of input circuits or groups of circuits (step 13). One or more of the evolved specialist optimisation scenarios are then selected to form a suite of optimisation scenarios (step 15) for use to optimise new circuits to be designed. In the operation phase 11, a new circuit to be optimised is input at step 18, and a plurality of optimisation scenarios from the suite of optimisation scenarios 15 is then used to try to optimise the new circuit (step 19).Type: ApplicationFiled: August 11, 2006Publication date: June 24, 2010Applicant: UNIVERSITY OF SUSSEXInventor: Adrian Dominic Thompson
