An electronic module housing having a rounded stylized dog-bone-type shape and an equatorial partial light bar. The shape provides a view of parts of the light bar from many locations. The controller circuitry can detect a malfunction among one or more of a plurality of current-drawing components by detecting that the total cumulative current drawing by all the components falls outside a predetermined nominal range.

A semi-flexible laminar silicone foam rubber-base heater for high temperature gas supply and exhaust lines used in microelectronic semiconductor fabrication uses superimposed adhesively bonded layers of an etched foil heater element containing layer, a high-to-low heat thermal transition layer, a thermal fuse laden silicone foam rubber insulation layer and a durable wrapping layer. The system can provide for the combined use of highly controllable etched foil heater elements, clean silicone foam rubber insulation, and inexpensive mechanical thermal fuses safely in a high heat gas supply and exhaust line environment.
