Abstract

Adaptive system for medical monitoring distributes data processing among computing devices connected to a network to optimize usage of computational resources, network communication speed and user experience. Data processing is distributed into several levels with bi-directional communication between the levels (computing devices) to coordinate and adjust data compression, filtering, and analysis, as well as the size of buffered data available for transmission and/or receiving.

Claims

1. A method for adaptive, multi-level processing of health data with said processing levels distributed among computing devices connected to a network of computers, said method comprising:

collecting at least one signal of an individual'"'"'s health data by substantially continuous monitoring said health data;

sending said at least one signal to a first computing device for first-level processing which includes detecting a plurality of primary elements of said data and processing said primary elements in low resolution to generate data respecting time intervals or amplitudes of said primary elements, storing reference values of said primary elements, and comparing said reference values with newly received data to produce qualitative indicators and quantitative data of differences between said reference values and said newly received data;

sending said signal after said first-level processing to a second computing device for second-level processing at higher resolution and analysis of changes, selected from at least one of continuous and serial changes, in at least some of the said primary elements in said data, using at least one method selected from mathematical decomposition and methods of artificial intelligence to improve at least one of said first-level and second-level processing, said second-level processing being adapted to correspond to at least one parameter selected from the user commands and computational resources of the network and said first and second computing devices;

exchanging information between said first-level and second-level processing, said exchanging adapted to correspond to at least one parameter selected from the network data-transfer rate, user commands and computational resources of said first and second computing devices; and

displaying at least the results of one of said first-level and second-level processing.

2. A method as set forth in claim 1 in which said computing devices are connected to at least one of a network of computers and the Internet.

3. A method as set forth in claim 1 that includes exchanging information between said two levels of processing to adapt and coordinate said two levels of processing with respect to at least one feature selected from speed, accuracy and display of said signal.

4. A method as set forth in claim 1 in which said signal that is compressed is stored in said remote computing device.

5. A method as set forth in claim 1 in which results of the second-level processing are displayed both quantitatively and qualitatively.

6. A method as set forth in claim 1 in which said at least one signal is collected from an MRI scanner.

7. A method as set forth in claim 6 in which at least a reference signal and a physiological signal are collected from substantially the same location on a subject and the reference signal is subtracted from the physiological signal to improve accuracy of the analysis.

8. A system for adaptive, multi-level processing of health data with said processing levels distributed among computing devices connected to a network of computers, said system comprising;

at least one sensor for collecting at least one signal of an individual'"'"'s health data by substantially continuous monitoring said health data;

at least one mobile (first) computing device for receiving said at least one signal and performing first-level processing of said at least one signal which includes detecting a plurality of primary elements of said data and processing said primary elements in low resolution to generate data respecting time intervals or amplitudes of said primary elements, storing reference values of said primary elements, and comparing said reference values with newly received data to produce qualitative indicators and quantitative data of differences between said reference values and said newly received data;

said at least one mobile computing device further having communication capability and software for network communication with at least one second computing device, which is adapted to perform second-level (higher-resolution) processing and analysis of changes, selected from at least one of continuous and serial changes, in at least some of the said primary elements in said data, using at least one method selected from mathematical decomposition and methods of artificial intelligence to improve at least one of said first-level and second-level processing, said second-level processing adapted to correspond to at least one parameter selected from the user commands, computational resources of a network and said first and second computing devices, and said mobile computing device further having communication capability for exchanging information with said second computing device to coordinate said two levels of processing using at least one parameter selected from the network data-transfer rate, user commands and computational resources of said first and second computing devices; and

said at least one mobile computing device having a display unit for presentation of said at least one signal and primary element, said presentation adapted to correspond to computational resources of said network, first computing device and second computing device.

9. A system as set forth in claim 8 in which said computing devices are connected through the Internet network.

10. A system as set forth in claim 8 in which said second computing device to perform second-level processing is selected from a network server and the Internet server.

11. A system as set forth in claim 8 in which said at least one mobile computing device is a cell phone.

12. A system as set forth in claim 8 in which said at least one signal is collected from an MRI scanner.

13. A system as set forth in claim 8 which includes a storage unit for storing the compressed signal to buffer said exchanging of information between computing devices.

14. A system as set forth in claim 8 which includes a compression unit that compresses waveforms using at least one type of mathematical transformation.
