A simple communications protocol enabling the Mobile Device to take full control of the power transfer Considerable design flexibility for integration of the system into a Mobile device Very low stand-by power achievable [implementation dependent] 1.3 Conformance and references All specifications in this document are mandatory, unless specifically indicated as recommended or optional or informative. To avoid any doubt the word"shall indicates a mandatory behavior of the specified component, i. e. it is a violation of this System Description Wireless Power Transfer if the specified component does not exhibit the behavior as defined. In addition, the word"should indicates a recommended behavior of the specified component, i. e, it is not a violation of this System Description Wireless Power Transfcr if the specified component has valid reasons to deviate from the defined behavior. And finally, the word"may" indicates an optional behavior of the specified component, i.e. it is up to the specified component whether to exhibit the defined behavior (without deviating there from] or not In addition to the specifications provided in this document, product implementations shall also conform to the specifications provided in the system descriptions listed below. Moreover, the relevant parts of the International Standards listed below shall apply as well. If multiple revisions exist of any System Description or International Standard listed he low, the applicable revision is the one that was most recently published at the release date nf this document.

A Mobile Device carries a logo to visually indicate to a user that the Mobile device complies with this System Description Wireless Power Transfer Operating Frequency The oscillation frequency of the Power Signal Packet a data structure that the Power Receiver uses to communicate a message to the Power Transmitter. A Packet consists of a preamble, a header byte, a message and a checksum, a packet is named after the kind of message that it contains Power receiver The subsystem of a Mobile device that acquires near field inductive power and controls its availa bility at its output, as defined in this System Description Wireless Power Transfer. For this purpose, the Power Receiver communicates its power requirements to the Power Transmitter. Power signal The oscillating magnetic: flux that is enclosed hy a Primary Cell and possibly a Secondary coil Power trans mitter The subsystem of a Base Station that generates near field inductive power and controls its transfer to a Power Receiver, as defined in this System Description Wireless power transfer Primary Cell A single Primary Coil or a combination of Primary Coils that are used to provide a sufficiently high magnetic flux through the Active Area Primary Cail A component of a Power Transmitter that converts electric current to magnetic flu Secondary coil The component of a Power Receiver that converts magnetic flux to electromotive force 1.5 Acronyms AC Alternating current DC Direct current EM Electro Magnetic EMC Electroc Magnetic Compatibility EMF Electro Magnetic Field C Wireless Power Consortium, September 2011 CONFIDENTIAL 【实例截图】
