1. A device comprising:

  • a first wireless power harvesting circuit configured to harvest a first wireless power signal from a wireless power source to produce a first power signal;

    a second wireless power harvesting circuit configured to harvest a second wireless power signal to produce a second power signal, wherein the first wireless power signal and the second wireless power signal are different types of wireless power signals;

    a component configured to programmably receive the first power signal and the second power signal;

    a profile module configured to generate data regarding current and historical energy profiles of the first wireless power signal and the second wireless power signal, wherein the generated data includes characteristics of charge capability of the first wireless power signal and the second wireless power signal determined from previous energy harvesting; and

    a control module programmably configured to control the reception of at least one of the first power signal from the first wireless power harvesting circuit and the second power signal from the second wireless power harvesting circuit by the component based on the data generated by the profile module and based on an amount of power available to the first harvesting circuit as compared to an amount of power available to the second harvesting circuit.
