1. A contactless power supply for inductively providing power to one or more remote devices by adapting to at least one of an addition, a removal, and a status change of said one or more remote devices, said contactless power supply comprising:
- a resonant circuit having a primary for transferring power to said one or more remote devices by an inductive coupling;
a receiver for receiving power information from a plurality of remote devices; and
a controller coupled to said receiver and to said resonant circuit for adapting said contactless power supply in response to at least one of said addition, said removal, and said status change of said one or more remote devices, wherein said controller is programmed to calculate one or more settings for said contactless power supply as a function of said received power information from two or more of said plurality of remote devices and wherein said controller is programmed to set said one or more calculated settings.

Abstract
An adaptive inductive ballast is provided with the capability to communicate with a remote device powered by the ballast. To improve the operation of the ballast, the ballast changes its operating characteristics based upon information received from the remote device. Further, the ballast may provide a path for the remote device to communicate with device other than the adaptive inductive ballast.

18. A method of operating a contactless power supply to inductively provide power to one or more remote devices by adapting to at least one of an addition, a removal, and a status change of said one or more remote devices, said method comprising:
-
polling a plurality of remote devices for power information; determining whether said number of said one or more remote devices has changed; calculating one or more settings as a function of said power information received from two or more of said plurality of remote devices, in response to determining that said number of said one or more remote devices has changed; and providing power from said contactless power supply to said one or more remote devices using said one or more calculated settings. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
