System for compression of physiological signals
First Claim
1. A method of optimizing retention of signal information from a physiologically generated digital signal, comprising steps of:
- generating a digital signal from a physiological source, the digital signal having an acquisition compression level;
storing the digital signal into a memory location as a stored digital signal, wherein the stored digital signal has a stored compression level;
identifying within the stored digital signal a preferred digital signal event exclusive of a non-preferred digital signal event, wherein the preferred digital signal event has higher clinical value than the non-preferred digital signal event;
detecting a memory storage limitation in the memory location; and
increasing the stored compression level of at least a portion of the stored digital signal in the memory location as a result of the memory storage limitation in the memory location.

Abstract
A method of optimizing retention of signal information from a physiologically generated digital signal is provided. The method can comprise steps of generating a digital signal from a physiological source, storing the digital signal into a memory location as a stored digital signal, identifying within the stored digital signal a preferred digital signal event exclusive of a non-preferred digital signal event, wherein the preferred digital signal event has a first event compression level and the non-preferred digital signal event has a second event compression level, detecting a memory storage limitation in the memory location, and increasing the second event compression level of the non-preferred digital signal event as a result of detecting a memory storage limitation. Also, the portable monitor can detect the presence of an upload source to which the digital signal can be uploaded in order to minimize the need to compress the signal.

32. A system for optimizing retention of signal information from a physiologically generated digital signal, comprising:
-
a signal recorder having an online mode and a remote mode; an online memory module operationally coupled to the signal recorder when in the online mode, such that the digital signal is stored in the online memory module when the signal recorder is in the online mode; a local memory module operationally coupled to the signal recorder when in the remote mode, such that the digital signal is stored in the local memory module as a stored digital signal when the signal recorder is in the remote mode, the stored digital signal being identified as having a preferred digital signal event exclusive of a non-preferred digital signal event, wherein the preferred digital signal event has higher clinical value than the non-preferred digital signal event; a local memory monitor operationally coupled to the local memory module to detect a memory storage limitation in the local memory module; a compression unit operationally coupled to the local memory module to compress at least a portion of the stored digital signal recorded by the signal recorder, wherein the preferred digital signal event has a first event compression level and the non-preferred digital signal event has a second event compression level; a control unit operationally coupled to the local memory module to evaluate a compression level of the stored digital signal; and an online detection unit operationally coupled to the control unit to detect when the signal recorder is in the online mode. - View Dependent Claims (33)
