Publication number: 20170362558Abstract: An apparatus is provided for mechanically loading a biological sample. The apparatus comprises: a container for housing the biological sample; a ferromagnetic element, for attachment to the biological sample within the container; and a solenoid for generating a magnetic field within the container, so as to apply a force to the ferromagnetic element. The solenoid is configured, when energised by a constant current, to produce a force on the ferromagnetic element that varies by less than a predetermined amount over a predetermined range of movement of the magnet within the container. A method of mechanically loading a biological sample is also disclosed.Type: ApplicationFiled: December 7, 2015Publication date: December 21, 2017Inventors: Jonathan Joshua Burton, Malcolm McCulloch, Mark Stuart Thompson, Chris Stevens

Patent number: 9318938Abstract: An electric machine (100) comprises a stator (112) and a rotor (114a, b) mounted for rotation about a rotor axis (120) with respect to the stator. Permanent magnets (124a, b) are carried by the rotor. The rotor has an output (190). The stator has coils (122) wound on stator bars (116) for interaction with the magnets. The rotor has two stages (114a,b) arranged one at either end of the stator bars, with two air gaps (126a,b) between the ends of the bars and the rotor stages. An annular housing (102, 142a, b, 146) retains and mounts the stator. A bearing (164a, b) is between the rotor and stator, the rotor being hollow around said rotor axis. There are two significant magnetic flux paths (30,30?) of the motor. The first passes between adjacent coils in a circuit on a substantially circumferential plane with respect to the axis (120). A second path 30? is in an axial plane, passing around the bearing.Type: GrantFiled: February 12, 2010Date of Patent: April 19, 2016Assignee: ISIS Innovation Ltd.Inventors: Nicholas Carpenter, Simon Dowson, Tim Woolmer, Chee Yeow Leong, William Treharne, Malcolm McCulloch

Patent number: 9176192Abstract: A method of identifying the operation of an electrical appliance comprising an induction motor is described. The method comprises identifying the operation of an electrical appliance including an induction motor when a path traced by real power values against corresponding reactive power values over a time period of interest comprises one or more substantially circular arcs. The real power values are related to the total real power supplied to one or more electrical appliances as a function of time, and the reactive power values are related to the total reactive power supplied to the one or more electrical appliances as a function of time. There is also described a related method of identifying the operation of a specified type of appliance, in which the operation of said specified type of appliance is dependent on a supply of at least one utility such as electricity, natural gas or water.Type: GrantFiled: July 21, 2010Date of Patent: November 3, 2015Assignee: INTELLIGENT SUSTAINABLE ENERGY LIMITEDInventors: James Donaldson, Sarah Surrall, Alexander Matthews, Malcolm McCulloch

Publication number: 20140347077Abstract: An apparatus has an input section arranged to receive values representative of the total instantaneous supply of electrical current as a function of time from an alternating voltage supply. Current waveforms comprising sets of values representative of the cyclic waveform of the electric current supply are obtained. A delta waveform generator calculates the difference between a current waveform and an earlier current waveform. An edge detector is arranged to detect an edge or edges in the delta waveform. An analysis section is arranged to identify at least one appliance load based at least on information on the edge or edges detected by the edge detector, and to determine the electrical energy consumed by said appliance load. Another apparatus has an input section arranged to receive values representative of the current supplied to an installation, such as a house. A store contains appliance data characteristic of the use of electricity by each of a plurality of appliances.Type: ApplicationFiled: April 29, 2014Publication date: November 27, 2014Applicant: ISIS INNOVATION LIMITEDInventors: James Donaldson, Malcolm McCulloch
