Method and apparatus for closed loop power estimation for determination of optimal placement of a power receive unit on a power transmit unit with visual and/or haptic feedback

A method for receiving wireless power, comprising:

• receiving a first amount of wireless power at a power receiving unit via a wireless field generated by a wireless power transmitter;
• measuring the first amount of wireless power;
• and
• providing an indication to a user on the power receiving unit whether at least a minimum power required to boot up a controller of the power receiving unit or establish communications with the wireless power transmitter, or a combination thereof has been met based on a comparison of the first amount of wireless power to a stored power threshold.

A non-transitory, computer-readable medium comprising code that, when executed, causes an apparatus for receiving wireless power to:

• receive a first amount of wireless power at a power receiving unit via a wireless field generated by a wireless power transmitter;
• measure the first amount of wireless power;
• and
• provide an indication to a user on the power receiving unit whether at least a minimum power required to boot up a controller of the power receiving unit or establish communications with the wireless power transmitter, or a combination thereof has been met based on a comparison of the first amount of wireless power to a stored power threshold.

An apparatus for receiving wireless power, comprising:

• means for receive a first amount of wireless power at the apparatus via a wireless field generated by a wireless power transmitter;
• means for measuring the first amount of wireless power;
• means for storing a power threshold;
• and
• means for instructing a feedback circuit to provide an indication to a user on the power receiving unit whether at least a minimum power required to boot up the apparatus or establish communications with the wireless power transmitter, or a combination thereof has been met based on a comparison of the first amount of wireless power to a selected one of the power threshold.
