Claim Text:
1. A retrofittable wireless power receiver for providing inductive power reception functionality to at least one host device, said retrofittable wireless power receiver comprising: a support platform; a secondary inductor operable to couple inductively with a primary inductor associated with a wireless power transmitter; a power reception circuit operable to control inductive power transfer from the primary inductor to the host device; a synchrorectifier comprising: at least two input terminals wired to said secondary inductor; at least two output terminals wired to at least two transmission power electrical contacts for providing a power channel to said host device; a first MOSFET having one anode wired to a first output terminal and one cathode wired to a first input terminal; a second MOSFET having one anode wired to said first output terminal and one cathode wired to a second input terminal; a third MOSFET having one anode wired to said first input terminal and one cathode wired to a second output terminal; and a fourth MOSFET having one anode wired to said second input terminal and one cathode wired to said second output terminal; a near field communication antenna; an array of electrical contacts comprising: a VOUT and GND pair of terminals wired to said sychrorectifier; a DISABLE terminal wired to said power reception circuit and configured to disable power transfer; and a pair of data contacts wired to said near field communication antenna.
