Abstract
A charge limited device that has only limited access to power can be operated to ensure a given operating time. The operating time may, for example, correspond to the time period between recharging of a battery. Instead of simply reducing power consumption, a budget is developed that enables dynamic monitoring of power consumption over that time to ensure that actual power consumption conforms to the budget.
Claims20
A method comprising:
- obtaining a measure of available power for a given period of time for a charge limited device;
- and
- monitoring ongoing power consumption to determine whether power consumption needs to be altered to ensure operation for said period of time.
An apparatus comprising:
- a charge limited power source;
- and
- a device to obtain a measure of available power from said power source for a given period of time and to monitor ongoing power consumption to determine whether power consumption needs to be altered to ensure operation for said period of time.
