1. A system for in-vivo measurement of blood glucose concentration in a human, comprising:
- a base station comprising,a base power source to supply power to components of the base station;
an implantable sensor for generating measurement signals that are correlated to a blood glucose concentration to be measured, the measurement signals being raw data recorded over first time intervals;
a signal processor that executes instructions for processing the measurement signals to produce compressed measurement data for second time intervals which are at least ten-times longer than the first time intervals, the measurement data being compressed at least ten-times compared to the measurement signals,base memory for storing the compressed measurement data;
a transmitter for wireless transmission of the compressed measurement data; and
,a display device comprising,a display device power source that has greater capacity than the base power source to supply power to components of the display device;
a user input for inputting data into the display device;
a receiver for receiving the wireless transmission of the compressed measurement data from the base unit,a microprocessor for processing the compressed measurement data to determine the blood glucose concentration;
a display for displaying blood glucose concentration.

Abstract
The analyte concentration, such as glucose, in a human or animal body is measured with an implantable sensor that generates measurement signals. The measurement signals are compressed through statistical techniques to produced compressed measurement data that can is easier to process and communicate. A base station carries the implantable sensor along with a signal processor, memory, and a transmitter. A display device is also disclosed that can receive the compressed measurement data from the base station for further processing and display.
