Abstract
A method for compressing data in an implantable device is provided. A current data sample is received. A difference value is determined between the current data sample and a previous data sample. The current data sample is compressed to at least one output symbol based on the difference value between the current sample and the previous data sample. Systems and programs of using the method are also provided.

A method for compressing data in an implantable device, comprising the steps of:
- receiving a current data sample;
- determining a difference value between the current data sample and a previous data sample;
- converting a sequence of similar output symbols to an escape output symbol;
- and
- compressing the current data sample to at least one output symbol based on the difference value between the current sample and the previous data sample.
An implantable medical device comprising:
- a processor;
- at least one sensor operably connected to the processor for collecting at least one data sample;
- wherein
- the processor receives a current data sample, determines a difference value between the current data sample and a previous data samples, converts a sequence of similar output symbols to an escape output symbol and compresses the current data sample to at least one output symbol based on the difference value.
An implantable medical system, comprising:
- means for receiving a current data sample;
- means for determining a difference value between the current data sample and a previous data sample;
- means for converting a sequence of similar output symbols to an escape output symbol;
- and
- means for compressing the current data sample to at feast one output symbol based on the difference value between the current sample and the previous data sample.
A computer usable medium including a program for compressing data in an implantable device, comprising:
- computer program code that receives a current data sample;
- computer program code that determines a difference value between the current data sample and a previous data sample;
- computer program code that converts a sequence of similar output symbols to en escape output symbol;
- and
- computer program code that compresses the current data sample to at least one output symbol based on the difference value between the current sample and the previous data sample.
