Abstract

A method of sending acquired graphical data over an alphanumeric paging service. The data is compressed, split into and blocks of a size which the paging service can handle, and transferred to the paging service. The paging service transmits the data to a wireless receiver attached to a computer. The computer displays the information on its display, and can further process the data.

Claims

1. A method of transmitting information, comprising the steps of:

sampling a set of data, thereby acquiring digital data;

converting said digital data to a format acceptable to a paging network, thereby creating a binary data stream in a non-graphical form;

transmitting said binary data stream over said paging network;

receiving said binary data stream;

unconverting said binary data stream, thereby creating said digital data; and

processing said digital data.

2. The method of claim 1, wherein said processing step further comprises the steps of:

generating a graphical image from said digital data; and

displaying said graphical image.

3. The method of claim 1, wherein said processing step further comprises the step of:

running a routine interpreting said digital data.

4. The method of claim 1, wherein said converting step further comprises the step of:

compressing said digital data to create compressed digital data prior to creating said binary data stream.

5. The method of claim 4, wherein said unconverting step further comprises the step of:

uncompressing said compressed digital data prior to creating said digital data.

6. The method of claim 5, wherein said compressing step further comprises the step of:

performing a first difference on said digital data by successively subtracting a data point in said digital data from the next data point in said digital data.

7. An apparatus for transmitting information, comprising:

means for sampling a set of data, thereby acquiring digital data;

a first processor for converting said digital data to a format acceptable to a paging network, thereby creating a binary data stream;

a paging provider for transmitting said binary data stream over said paging network;

a pager for receiving said binary data stream;

a second processor for unconverting said binary data stream, thereby creating said digital data; and

said second processor also for processing said digital data.

8. The apparatus of claim 7, wherein said second processor further comprises means for generating a graphical image from said digital data, said paging network further comprising:

a display for displaying said graphical image.

9. The apparatus of claim 8, wherein said second processor further comprises:

means for running a routine interpreting said digital data.

10. The apparatus of claim 7, wherein said converting means further comprises:

means for compressing said digital data to create compressed digital data prior to creating said binary data stream.

11. The apparatus of claim 10, wherein said unconverting means further comprises:

means for uncompressing said compressed digital data prior to creating said digital data.

12. The apparatus of claim 11, wherein said compressing means further comprises:

means for performing a first difference on said digital data by successively subtracting a data point in said digital data from the next data point in said digital data.

13. The apparatus of claim 7, further comprising:

an electrocardiograph for acquiring an electrocardiogram from a patient, said electrocardiogram being said set of data.

14. The apparatus of claim 8, further comprising:

an electrocardiograph for acquiring an electrocardiogram from a patient, said electrocardiogram being said set of data;

wherein said graphical image is a waveform of said electrocardiogram.

15. The apparatus of claim 9, further comprising:

an electrocardiograph for acquiring an electrocardiogram from a patient, said electrocardiogram being said set of data;

wherein said routine interpreting said digital data analyzes said electrocardiogram.

16. The apparatus of claim 13, wherein said first processor is in said electrocardiograph.
