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.

Visibility electronic controller and current-based status monitor

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.

Electronic controller module

A moisture-sealing and thermally-isolating miniature implement for terminating a mineral-insulated and metal-sheathed cable and connecting it to a power source, includes a hollow contact prong protruding from one axial end of a metallic heat-sink barrel penetrated from an opposite end by the steel sheath of a heating element cable. The heating element contacts a nickel or nickel clad iron pin that penetrates the prong and is welded to its most distal extremity. The sheath is welded to the proximal end of the barrel by a hermetic brazed joint, and the distal end of the barrel is hermetically plugged around the prong by a metalized alumina ceramic seal. The copper pin is connected to the end of the heating element within the sheath and mineral insulation. The barrel is machined to have a series of deep peripheral grooves that act as thermal conductivity reducing chokes.
