Abstract: Apparatus and methods for envelope tracking calibration are provided. In one embodiment, a method of calibrating an envelope tracker having an envelope shaping table generated at a desired gain compression of a power amplifier is provided. The method includes generating a supply voltage for the power amplifier using the envelope tracker, operating the supply voltage of the power amplifier at a first voltage level associated with substantially no gain compression of the power amplifier, and measuring an output power of the power amplifier at the first voltage level. The method further includes decreasing a voltage level of the supply voltage one or more times and measuring the output power at each voltage level, determining a second voltage level of the power amplifier associated with a gain compression equal to about that of the desired gain compression, and calibrating the envelope tracker based on the determination.

Abstract: Non-pressurized shaving compositions are described that provide a warm/hot sensation during use as the result of an exothermic redox reaction. The compositions are post-foaming via nascent gas release in situ due to the generation of carbon dioxide. The carbon dioxide induced foam is maintained for several minutes after the compositions are dispensed, whereby the compositions are capable of providing both a warm sensation and sustained lather, a balance which heretofore has been a significant challenge.
