Patent number: 9978196Abstract: A banknote acceptor 1 for authenticating a banknote 2, has a sensing station S with detector 18 that produces image signals corresponding to a face the banknote. A processor 24 pre-processes the image signals and compares them with stored reference data corresponding to an acceptable banknote from memory 25 to determining the authenticity of the banknote and its denomination. A display device 29 displays an image 31 corresponding to the banknote under test based on the image signals from the detector 18, to allow the user to perform a visual check that the banknote detected at the sensing station corresponds to the banknote under test presented by the user. Also, the detected denomination of the banknote is displayed on device 32. The user can accept or reject the banknote using buttons 33 and 34, and retrieve images of previously accepted banknotes with button 35.Type: GrantFiled: June 27, 2012Date of Patent: May 22, 2018Assignee: Crane Payment Innovations LimitedInventors: John Ashby, Andrew William Barson, Malcolm Bell, Les Hutton, Kevin Mulvey

Patent number: 8417016Abstract: An acceptor device for sheet objects such as banknotes, comprises a sensor to derive data corresponding to a spatial array of data samples from a face of a sheet object, said data being configured in a sampling frame that lies within a range of positional relationships to a reference frame. The acceptor device also comprises a processor operable to process the data to determine the relationship between the reference frame and the sampling frame for the sensed data, and being operable to transform pre-selected regions of the sensed data from the sampling frame so as to correspond to data in the reference frame, and to make a comparison of the transformed data with reference data corresponding to the pre-selected regions in the reference frame and to the sheet object depending on the outcome of the comparison.Type: GrantFiled: December 13, 2005Date of Patent: April 9, 2013Assignee: Money Controls LimitedInventors: Malcolm Reginald Hallas Bell, Kevin Charles Mulvey, Andrew William Barson, John Ashby

Patent number: 7603222Abstract: A method and system is provided for identifying in-range sensor faults in a gas turbine engine, by observing the tracked component qualities in an embedded model and recognizing anomalous patterns of quality changes corresponding to sensor errors. An embedded model of the engine is employed to estimate sensed parameters such as rotor speeds, temperatures and pressures, as well as other parameters that are computed based on input parameters. Each major rotating component of the engine, including the fan, compressor, combustor, turbines, ducts and nozzle is individually modeled. Sensor failures are detected by identifying anomalous patterns in component quality parameters. A library of anomalous patterns is provided for comparing quality parameters generated by a tracking filter with the library of anomalous patterns. If a pattern is matched, a sensor may be eliminated from the tracking filter and the estimated model parameter used to avoid corrupting the model quality parameters.Type: GrantFiled: November 18, 2005Date of Patent: October 13, 2009Assignee: General Electric CompanyInventors: Matthew William Wiseman, Malcolm John Ashby
