Power management for a self-powered device scheduling a dynamic process

A device comprising:

• a battery;
• a memory;
• an interface to a plurality of sensors each configured to sample a current state of a dynamic process, said dynamic process having a sampling rate;
• a data acquisition circuit having a first clock rate based on said sampling rate, wherein said data acquisition circuit is configured to perform a read of sensor information from said sensors;
• and
• a processor having a second clock rate, wherein said processor is configured to (A) process said sensor information from said data acquisition circuit, (B) generate a monitoring signal in response to at least one of (i) said sensor information (ii) a model of said dynamic process and (iii) a desired state of said dynamic process, (C) schedule procedures for said device and (D) determine computation times for said procedures based on context information, wherein (a) said second clock rate is faster than said sampling rate, (b) said procedures comprise at least one of (i) reading said sensor information, (ii) writing data to said memory, (iii) transmitting said monitoring signal to a second device and (iv) entering a standby mode of operation to conserve power and (c) said procedures are scheduled based on (i) said sampling rate of said dynamic process, (ii) said computation times for said scheduled procedures and (iii) opportunities to enter said standby mode.
