Systems and methods for nullifying energy levels for wireless power transmission waves

摘要

Systems and methods to generate and transmit power waves are disclosed herein. An example method includes: receiving, by a transmitter, from one or more sensors, location data about a location associated with one or more objects within a transmission field of the transmitter. The one or more sensors may include a proximity sensor configured to send the location data of the one or more objects, and the one or more objects are associated with a maximum permissible exposure (MPE) level. The method also includes: transmitting, by the transmitter, one or more power waves to converge to form a pocket of energy at a location of an electronic device; and transmitting, by the transmitter, one or more power waves to converge destructively to form a null space at the location of the one or more objects, the null space having a power density level that is below the MPE level.
