Method and apparatus for modular power management and protection of critical services in ambulatory medical devices
First Claim
1. A computer-implemented method for managing power consumption of a battery-operated device configured to provide a plurality of services, comprising, performing by a processor:
- receiving a battery level of said device, at least one parameter of a user of the device, and the services being provided by the device, constructing time profiles encoding a probability of at least one of said battery level, user parameter, and services being provided having certain values at each of a number of time segments k;
setting a fidelity policy u(k) for each time segment k, said fidelity policy defining a level of fidelity for each service, based on said time profiles and battery level;
computing, based on said time profiles, an amount of time remaining before battery exhaustion under said battery level and a mode of operation having a predefine power consumption rate, and taking a predetermined action based on the computed amount of time remaining with respect to at least one preset threshold; and
regulating access of said services to resources of said device for performing said services, in accordance with said predetermined action.

Abstract
Architecture and associated methods are provided for power management of ambulatory medical devices. The medical devices is described by a suite of services, each assigned a level of priority (from discretionary to critical), and the power management architecture allows use interchangeable control modules of various levels. A Power Safety Controller supervises the system to ensure appropriate preservation of critical services and provide warnings for low battery level. A Fidelity Controller ensures optimal allocation of power between the different services. A device supervision module estimates device characteristics which can be used by the other levels. The overall architecture ensures a safe and optimal management of services, and allows for a bottom-up deployment of the device.
