Open the CIPO recordAbstract From the Canadian patent
Methods, apparatus, and articles of manufacture to power a device using wirelessly transmitted power are disclosed. Initially a wireless base unit obtains a request for wireless power. The wireless base unit then determines a power requirement associated with a wireless field unit and compares the power requirement to a remaining power capacity of the wireless base unlit. The wireless base unit then transmits power wirelessly to the wireless field unit based on the comparison of the power requirement to the remaining power capacity. The wirelessly transmitted power is associated with powering a field device operatively coupled to the wireless field unit.
