An on-resistance of a junction FET is reduced. The novel technique is based on the use of probability distribution functions and cumulative distribution functions to characterize the impulse response of the RC circuit, and the calculating steps derive the first and second circuit response parameters from such statistical distribution functions. The time-dependent state is determinable by software calculations using continuous measurements along the pipeline. At least some of the tracking or analysis can be performed by clients that access the online communities, by a server of each online community, andor by a central tracking system. The temperature adjuster changes a temperature of the housing. The methodology can be implemented as instructions implemented in a computer readable medium.
