An example method disclosed herein includes: determining, by a transmitter, whether to transmit one or more power waves to a receiver location along a transmission path by comparing a receiver location and a path of the one or more power waves with a stored location of an entity to be excluded from receipt of power waves. The method also includes: measuring, by one or more sensors of the transmitter, power levels in a transmission field of the transmitter, the transmission field including the receiver location and the entity; and upon determining that (i) the entity to be excluded is not at the receiver location and not in the path and (ii) a measured power level at the receiver location does not exceed one or more permissible power levels for safe wireless power transmission, transmitting, by the transmitter, the power waves along the path to converge at the receiver location.

1. A method for wireless power transmission, comprising: determining, by a transmitter, whether to transmit one or more power waves to a receiver location along a transmission path by comparing a receiver location and a path of the one or more power waves with a stored location of an entity to be excluded from receipt of the power waves;measuring, by one or more sensors of the transmitter, power levels in a transmission field of the transmitter, the transmission field including the receiver location and the entity; andupon determining that the entity to be excluded is not at the receiver location and not in the path and (ii) a measured power level at the receiver location does not exceed one or more permissible power levels for safe wireless power transmission, transmitting, by the transmitter, the one or more power waves along the path to converge at the receiver location. 2. The method according to claim 1, wherein determining whether to transmit the one or more power waves further comprises receiving, by the transmitter, the stored location from a user device configured to indicate the stored location of at least one entity to be excluded from receipt of the one or more power waves. 3. The method of claim 1, wherein determining whether to transmit the one or more power waves further comprises receiving, by the transmitter, the stored location from a database storing one or more stored locations for one or more entities to be excluded from receipt of the one or more power waves. 4. The method of claim 1, wherein determining whether to transmit the one or more power waves further comprises receiving, by the transmitter, the stored location for the entity to be excluded from receipt of the one or more power waves from at least one remote sensor configured to scan the transmission field for one or more entities in the transmission field. 5. The method of claim 1, wherein determining whether to transmit the one or more power waves further comprises receiving, by the transmitter, the stored location via a graphical user interface (GUI) of the transmitter. 6. The method of claim 1, wherein determining whether to transmit the one or more power waves to the receiver location further comprises: receiving, by the transmitter, from the receiver via a communications signal mapping data indicating the receiver location; anddetermining, by the transmitter, the receiver location based upon the mapping data indicating the receiver location as received from the receiver. 7. The method of claim 1, wherein the receiver location comprises a set of coordinates of a region in space within the transmission field. 8. The method of claim 1, further comprising reducing, by the transmitter, a power level of the one or more power waves that converge at the receiver location, upon determining that the entity to be excluded is at the receiver location. 9. The method of claim 1, further comprising terminating, by the transmitter, transmission of the one or more power waves upon determining that the stored location for the entity to be excluded coincides with the receiver location or intersects the path of the one or more power waves. 10. A transmitter for wireless power transmission comprising: at least two antennas;a database operatively coupled to a controller, including a stored location indicating a location in transmission field for an entity to be excluded from receiving one or more power waves; andthe controller configured to control the one or more power waves transmitted by the transmitter through the at least two antennas that converge in a three dimensional space to form one or more pockets of energy at a receiver location,wherein the controller is configured to: determine whether the stored location for the entity to be excluded is at the receiver location or in a path of the one or more power waves when transmitted to the receiver location,measure, via one or more sensors of the transmitter, power levels in the transmission field of the transmitter, the transmission field including the receiver location and the entity, andtransmit the one or more power waves along the path to converge at the receiver location upon determining that (i) the entity to be excluded is not at the receiver location and not in the path to the receiver location, and (ii) a measured power level at the receiver location does not exceed one or more permissible power levels for safe wireless power transmission. 11. The transmitter of claim 10, wherein the transmitter is further configured to receive the stored location for the entity to be excluded from a user device in communication with the controller via a communications signal. 12. The transmitter of claim 11, wherein the user device is configured to generate a set of coordinates within the transmission field for the stored location, and transmit the set of coordinates for the stored location to the controller. 13. The transmitter of claim 10, wherein the transmitter is further configured to receive the stored location of the entity to be excluded from receipt of the one or more power waves from at least one sensor that is: coupled to the controller via a communications signal andconfigured to scan the transmission field for one or more entities in the transmission field. 14. The transmitter of claim 10, wherein the transmitter further comprises at least one sensor selected from the group consisting of: a passive sensor, an active sensor, a smart sensor, an infrared sensor, a pyro-electric sensor, an ultrasonic sensor, a laser sensor, an optical sensor, an Doppler sensor, an accelerometer, a microwave sensor, a millimeter sensor, a resonant LC sensor, and an RF standing wave sensor. 15. The transmitter of claim 10, wherein the transmitter is further configured to receive the stored location via a graphical user interface (GUI) coupled to the controller. 16. The transmitter of claim 10, wherein the controller is further configured to receive from the receiver mapping data indicating the receiver location via a communications signal, and determine the receiver location based upon the mapping data. 17. The transmitter of claim 10, wherein the transmitter is further configured to reduce a power level of the one or more power waves that converge at the receiver location upon determining that the stored location for the entity to be excluded is at the receiver location or in the path of the one or more power waves. 18. The transmitter of claim 10, wherein the transmitter is further configured to terminate the one or more power waves upon determining that the stored location for the entity to be excluded coincides with the receiver location or is in the path of the one or more power waves. 19. A method for wireless power transmission comprising: receiving, by a transmitter, from a tagging device, a device tag containing data indicating a first location of an entity to be excluded from receipt of power waves;determining, by the transmitter, a second location of a receiver and a path of one or more power waves to the receiver;determining, by the transmitter, whether the first location as indicated by the device tag is the same as the second location or in the path of the one more power waves;measuring, by one or more sensors of the transmitter, power levels in a transmission field of the transmitter, the transmission field including the second location of the receiver and the first location of the entity; andtransmitting, by the transmitter, the one or more power waves along the path to converge at the second location of the receiver when the first location is not the same as the second location and not in the path of the one or more power waves and (ii) a measured power level at the second location of the receiver does not exceed one or more permissible power levels for safe wireless power transmission. 20. The method according to claim 19, wherein the data of the device tag includes a set of coordinates within the transmission field for the first location of the entity to be excluded.
