Abstract: A flexible, substantially lamellar silicone foam rubber-based heater for heating fluid lines such as high temperature gas supply and exhaust lines used in microelectronic semiconductor fabrication uses a flexible, oblong substantially longitudinally uniform heater body including an oblong block of a thermally conductive, resiliently compressible material for conforming the heater to a line of complexly shaped components connected in series. The block can be supported by a silicone rubber support layer in contact with a flexible heater element containing layer, and an outer silicone foam rubber insulation layer. Fasteners, such as separatable retaining bands spaced along the line can hold the heater in place. A matable pair of bodies, or a single folded body can enwrap the line.

Abstract: A substantially planar oblong panel of flexible material such as silicone foam rubber can be wrapped on a thermally sensitive fluid conduit to insulate it against unwanted thermal changes. The panel can be formed to have a plurality of voids on its inner surface. The voids can be in the form of a number of parallelly spaced apart longitudinal flutes separated by raised buttes therebetween. The elongated flutes can be substantially wedge-shaped to allow them to collapse when the panel is wrapped upon a substantially cylindrical conduit such as a pipe. The angular separation between buttes can be selected so that the flutes are substantially eliminated when the block is completely installed upon the conduit of a given diameter. The flutes allow for greater flexibility of the block during installation.

Abstract: 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.

Abstract: 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.
