1. A method for detecting malfunctions in medical sensors comprising:
- by one or more computing devices,accessing, from a first medical sensor, a first binary decision diagram (BDD) representing medical sensor data from the first medical sensor, the medical sensor data measuring physiological stimulus from a person'"'"'s body;
determining a first compression rate of the first BDD accessed from the first medical Sensor;
indicating a malfunction in connection with the first medical sensor if the first compression rate is outside of a predetermined compression-rate range; and
size optimizing storage of the medical sensor data by;
if a malfunction is not indicated, then storing the first BDD in a data store associated with the first medical sensor; and
if a malfunction is indicated, then deleting the first BDD from the data store associated with the first medical sensors.

Abstract
In particular embodiments, a method includes analyzing a binary decision diagram (BDD) representing a data stream from a sensor to determine a compression rate of the BDD and indicating a sensor malfunction in the sensor if the compression rate of the BDD deviates from a specified compression rate range.
