The embodiments disclosed herein describe a method of a power controller for monitoring for unsafe operating conditions of a drive transistor in a switching power converter of a LED lamp system by predicting the power dissipation of the drive transistor based on knowledge of the current through the drive transistor and a continuous observation of the voltage across the drive transistor. The present invention allows the application software to execute in a secured run-time environment. The foam is viscous and shelf-stable, and can be combined with a viscous food product to lower its caloric density and improve its organoleptic properties. The bottom member portions are selectively coupled together using tab and channel structures.
