Patent number: 9262319Abstract: The present invention is directed to a method for increasing the operational lifetime of a flash memory device, wherein, the method comprises varying the operating parameters of the flash memory device over the lifetime of the flash memory device. The advantage of providing a method which varies the operating parameters of a flash memory device is that the operational lifetime of the flash memory device will be increased. Relatively low voltages and relatively short voltage periods may be used initially to write to, read from and erase the flash cells in the flash memory device. As time passes, the flash cells in the flash memory device will begin to degrade and it will be necessary to increase the voltage and the period of the voltage applied to the flash memory device in order to ensure that the correct write, read and/or erase commands are carried out. The invention is also directed towards a flash memory device.Type: GrantFiled: February 16, 2015Date of Patent: February 16, 2016Assignee: NATIONAL DIGITAL RESEARCH CENTRE LIMITEDInventors: Conor Maurice Ryan, Joseph Sullivan

Publication number: 20120330683Abstract: A method and system for evaluating a subject's weight calculates a moving average of the weight of the subject based on several consecutive weight measurements e.g. on consecutive days. Rather than looking for absolute weight gains of e.g. 2 kg in 48 hours, as with currently accepted guidelines, each new measurement is compared with the calculated moving average, and a first form of alert is generated if the new measurement differs from the calculated moving average by more than a with expected range threshold amount such as by one standard deviation. If the first form of alert is generated consecutively on a predetermined number of successive iterations, a second form of alert is generated different from the first form of alert. The system and method does not assume a stable underlying patient weight, and absolute weight gains over e.g.Type: ApplicationFiled: February 25, 2011Publication date: December 27, 2012Applicants: CROFTON CARDIAC SYSTEMS LIMITED, THE NATIONAL DIGITAL RESEARCH CENTRE LIMITED, UNIVERSITY COLLEGE DUBLIN, BIANCAMED LIMITEDInventors: Mark Ledwidge, Kenneth McDonald

Publication number: 20120230501Abstract: The present invention provides an auditory test and compensation method for an audio system comprising an audio device coupled to an audio output means and a listener of the audio device. The method comprises the steps of: delivering a series of audio stimuli through the audio output means; capturing a listener's response to the audibility of the stimuli; calculating a compensation print from the frequency response; deriving a filter from the calculated compensation print with respect to the frequencies associated with the frequency response and applying the filter to an audio signal of the audio system.Type: ApplicationFiled: September 2, 2010Publication date: September 13, 2012Applicants: NATIONAL DIGITAL RESEARCH CENTRE, UNIVERSITY COLLEGE DUBLIN, CLEARTONE TECHNOLOGIES LIMITEDInventors: Declan Ganter, Fintan Graham, Martin Ganter, Scott Rickard, Dan Barry, Kevin Jennings, Denis Kozlov
