Inventor: WILLIS ANDRE
IPC: G01D1/14
Filed: 2006-03-07
Abstract: Disclosed herein is a method and apparatus used to the measure duty cycle of a clocking waveform utilizing minimal hardware and achieving high accuracy. This invention utilizes digital sampling of the signal to be measured at a rate that can be significantly lower then the clocking frequency of the signal to be measured.  It accomplishes broad-band, multi-frequency use by using a time-varying frequency for the sampling clock to make sure that the sampling clock is asynchronous with the frequency of the clocking signal to be measured. The average ratio of the sampled ones (or zeros) as compared to the total number of samples is then computed to derive the measurement of duty cycle.

Title: Machine learning for classification of magneto cardiograms
Inventor: STERNICKEL KARSTEN
IPC: A61B5/08
Filed: 2004-07-01
Abstract: The use of machine learning for pattern recognition in magnetocardiography (MCG) that measures magnetic fields emitted by the electrophysiological activity of the heart is disclosed herein. Direct kernel methods are used to separate abnormal MCG heart patterns from normal ones. For unsupervised learning, Direct Kernel based Self-Organizing Maps are introduced. For supervised learning Direct Kernel Partial Least Squares and (Direct) Kernel Ridge Regression are used. These results are then compared with classical Support Vector Machines and Kernel Partial Least Squares. The hyper-parameters for these methods are tuned on a validation subset of the training data before testing. Also investigated is the most effective pre-processing, using local, vertical, horizontal and two-dimensional (global) Mahanalobis scaling, wavelet transforms, and variable selection by filtering. The results, similar for all three methods, were encouraging, exceeding the quality of classification achieved by the trained experts. Thus, a device and associated method for classifying cardiography data is disclosed, comprising applying a kernel transform to sensed data acquired from sensors sensing electromagnetic heart activity, resulting in transformed data, prior to classifying the transformed data using machine learning.

Filed: 2004-10-25
Abstract: An intelligent power management system that includes a circuit breaker containing a PLC module that spans open contacts of the circuit breaker to provide a communication path for PLC messages between the line and load sides of the circuit when the contacts are open. The contacts are motorized to permit remote operation through PLC messaging. Coupled to the PLC module is a controller, which controls the opening and closing of the motorized contacts under user control or via an adaptive load management algorithm that reduces peak power consumption and adapts a set of loads to changed power supply conditions. The controller can also dynamically alter operational current and fault threshold levels on a real-time basis based upon circuit requirements or environmental conditions. The algorithm runs a state machine and also manages loads in a limited power source environment such as when loads are powered by a generator.
