Apparatus, system and method of multiple device wireless power transfer
First Claim
1. An apparatus of wireless power transfer, the apparatus comprising:
- a Wireless Power Transmitter (WPT) to transmit a wireless power signal to be received by a plurality of Wireless Power Receivers (WPRs), wherein said WPT is to detect one or more load modulation events within a predefined time interval based on a change in a load on said wireless power signal, and to determine an amount of power to be provided to said plurality of WPRs based on a number of said load modulation events and durations of said load modulation events, wherein said WPT is to determine the amount of power to be provided to said plurality of WPRs based on a sum of the durations of said load modulation events.

Abstract
Some demonstrative embodiments include apparatuses, systems and/or methods of wireless power transfer. For example, an apparatus may include a wireless power controller to communicate between a Wireless Power Receiver (WPR) and a Wireless Power Transmitter (WPT) an indication of a requested amount of power to be provided from the WPT to the WPR via a wireless power signal, said indication is in the form of a load modulation event within a predefined time interval, said load modulation event comprises a change in a level of a magnetic field of said wireless power signal, a duration of said load modulation event is based on the requested amount of power to be provided from the WPT to the WPR.

9. A product including a non-transitory, tangible storage medium having stored thereon instructions that, when executed by a machine, cause a Wireless Power Transmitter (WPT) to:
-
transmit a wireless power signal to be received by a plurality of Wireless Power Receivers (WPRs); detect one or more load modulation events within a predefined time interval based on a change in a load on said wireless power signal; and determine an amount of power to be provided to said plurality of WPRs based on a number of said load modulation events and durations of said load modulation events, wherein said instructions, when executed, cause the WPT to determine the amount of power to be provided to said plurality of WPRs based on a sum of the durations of said load modulation events. - View Dependent Claims (10, 11, 12, 13)
