Patent number: 10135179Abstract: A system for providing power to a cordless appliance is provided. The system includes a coupler, and a complementary coupler on the appliance is also present. The coupler has symmetrically configured concentric power terminals, which are connected to a main power source in use, and a magnetic coupling region disposed concentrically around an outer periphery of the power terminals. The complementary coupler has complementary power terminals configured to engage with the symmetrically configured concentric power terminals of the coupler, and an engaging region disposed concentrically around an outer periphery of the complementary terminals. A magnetic force provides a mutual attraction between the magnetic coupling region and the engaging region, thereby engaging the power terminals and complementary power terminals and establishing an electrical connection between the coupler and the appliance.Type: GrantFiled: November 5, 2015Date of Patent: November 20, 2018Assignee: Sunbeam Corporation Pty LtdInventors: Peter Cooper, Andrew Chan, Maxim Guyatt, Andrew Morgan, Christopher Elliott, Mark Whitcombe

Patent number: 9273350Abstract: A method for the detection of a target nucleic acid, which method comprises contacting template nucleic acid from a sample with (i) a signalling system and (ii) a tailed nucleic acid primer having a template binding region and the tail comprising a linker and a target binding region, in the presence of appropriate nucleoside triphosphates and an agent for polymerisation thereof, under conditions such that the template binding region of the primer will hybridise to a complementary sequence in the template nucleic acid and be extended to form a primer extension product, separating any such product from the template whereupon the target binding region in the tail of the primer will hybridise to a sequence in the primer extension product corresponding to the target nucleic acid, and wherein any such target specific hybridisation causes a detectable change in the signalling system, such that the presence or absence of the target nucleic acid in the sample is detected by reference to the presence or absence of a deType: GrantFiled: June 8, 2004Date of Patent: March 1, 2016Assignee: QIAGEN MANCHESTER LIMITEDInventors: David Mark Whitcombe, Jane Theaker, Neil James Gibson, Stephen Little

Patent number: 7001721Abstract: Disclosed are methods for determining the presence or absence of a target nucleic acid (e.g. DNA) sequence in a sample nucleic acid, the method comprising: (a) exposing the sample to a detection agent comprising a colloid metal surface associated with a SER(R)S active species (SAS) such as an azo dye and with a target binding species (TBS) which may be PNA which is complementary to the target, and (b) observing the sample agent mixture using SER(R)S to detect any surface enhancement of the label wherein the binding of the TBS to the target sequence causes surface enhancement SAS.Type: GrantFiled: May 20, 1999Date of Patent: February 21, 2006Assignee: University of StrathclydeInventors: David Mark Whitcombe, Duncan Graham, William Ewen Smith

Patent number: 6270967Abstract: A method for the detection of diagnostic base sequences in a sample nucleic acid comprises contacting the sample in the presence of appropriate nucleoside triphosphates and an agent for polymerization thereof with a diagnostic primer for the diagnostic base sequence, the primer having a tail sequence comprising a tag region and a detector region such that an extension product of the primer is synthesized when the corresponding base sequence is present in the sample, and any extension product of the diagnostic primer acting as a template for extension of a further primer which hybridizes to a locus at a distance from the diagnostic base sequence. The sample is contacted with a tag primer which selectively hybridizes to the complement of the tag sequence in an extension product of the further primer and is extended, and the presence or absence of the diagnostic base sequence is detected by reference to the detector region in the further primer extension product.Type: GrantFiled: October 29, 1998Date of Patent: August 7, 2001Assignee: Zeneca LimitedInventors: David Mark Whitcombe, Jannine Brownie, Stephen Little
