SYSTEM AND METHOD FOR CONSERVING POWER IN A MEDICAL DEVICE
First Claim
1. A method for conserving electrical power in a therapeutic medical device, the therapeutic medical device having a general purpose processor and a critical purpose processor, the method comprising:
- instructing the general purpose processor to enter a reduced service state;
detecting, on the critical purpose processor, at least one event that requires processing by the general purpose processor;
instructing the general purpose processor to enter an active state; and
processing, on the general purpose processor, the at least one event.

Abstract
A system and method for conservation of battery power in a portable medical device is provided. In one example, a processor arrangement that includes a plurality of processors is implemented. At least one of these processors is configured to execute the critical functions of the medical device, while one or more other processors assume a reduced service level, thereby drawing significantly less power. According to this arrangement, the medical device conserves energy by drawing the additional electrical power needed to activate the additional processing power only when needed.
