摘要： A localized cardiac measure, such as a localized measure of myocardial ischemia, is obtained by applying sensors to a subject, where the sensors are configured to produce electrical signals representative of cardiac activity of the subject. The subject's heart is then physiologically stressed by, for example, exercise stress testing, and electrical signals are received from at least two of the sensors. The received signals then are processed to obtain a localized cardiac measure.

摘要： Method and apparatus for analyzing ECG signal data for diagnostic purposes by performing an incrementally moving, short window FFT analysis to produce a set of spectral templates representative of the spectral frequency content of the ECG at each window position. The spectral templates may be displayed as a representation of a three dimensional surface or mathematically analyzed. The changes in the shape of the templates or surface with time represent a change in the spectrum, which are shown to be an indication of abnormalities in the heart.

摘要： A vibration recorder for detecting leaks in a pipeline network includes a sensor operable to receive vibration signals from a pipeline network, and a communication port connected to an automatic meter reader/transmitter (“AMRT”). A processor connected to the communication port and to the sensor is programmed to process the vibration signals and to send data regarding the processed vibration signals to the AMRT using the communication port. The vibration recorder may also include metering functions, and, in some implementations, may also incorporate the functions of the AMRT.

摘要： Tracking vibrations on a pipeline network includes installing multiple vibration recorders on the pipeline network, with each recorder including a sensor, a processor, and a communication device. At each vibration recorder, vibration signals are received from the sensor at programmed times under the control of the processor of the vibration recorders and processed by the processor. The processed vibration signals are communicated from the vibration recorder to a reader device using the digital communication device. In addition, at a particular vibration recorder, meter readings from a flow meter associated with the particular vibration recorder are received. The meter readings are indicative of a level of flow in the pipeline network, and are communicated from the particular vibration recorder to a reader device using the communication device of the particular vibration recorder. Thereafter, the processed vibration signals from the one or more reader devices are collected at a central computer system. Finally, the collected processed vibration signals and the meter readings are analyzed at the central computer system to determine abnormal vibration patterns and to obtain measures of any leaks present in the pipeline network.

摘要： Noise is reduced from a received ECG signal representative of activity of the heart of a patient. A collection of beats from the ECG signal is selected and transformed into a multi-dimensional representation. A multi-dimensional filter function is applied to the multi-dimensional representation to enhance a signal-to-noise ratio of the collection of beats.
