Abstract: A controller for a lamp, comprising an input terminal for receiving a requested-color-signal representative of a requested-color-value to be provided by the lamp and one or more temperature-values associated with the lamp. The controller includes a full-color-module for providing a full-color-lamp-control-signal for an output terminal; a stabilization-module for providing a stabilized-lamp-control-signal for the output terminal; and a mode controller for comparing the requested-color-value with a threshold value. If the requested-color-value satisfies the threshold value, then the stabilization-module provides the stabilized-lamp-control-signal to the output terminal. If the requested-color-value does not satisfy the threshold value, then the full-color-module provides the full-color-lamp-control-signal to the output terminal.

Abstract: A method for performing foreign object detection in an inductive wireless power transfer system is disclosed. In the embodiment, the method involves obtaining measurements from a base station of a wireless power transfer system during charging and determining transmitter energy loss in a power transmitter, Ptxloss, using the obtained measurements, wherein the transmitter energy loss, Ptxloss, is a function of at least Vcap and PTx, wherein Vcap is proportional to the voltage amplitude across the capacitor of an LC tank circuit in a power transmitter and PTx is the total power supplied to the power transmitter. The method also involves detecting the presence of a foreign object in response to the estimated transmitter energy loss.
