A sign-monitoring system includes at least one electronic sign and a controller comprising a processor and memory. The electronic sign includes a pixel array, the pixel array including a plurality of pixels. The electronic sign further includes an embedded controller coupled to the at least one electronic sign. The embedded controller develops diagnostic information for the at least one electronic sign, the diagnostic information including information related to a number of malfunctioning pixels in the plurality of pixels. The controller is communicably coupled to the embedded controller and receives at least a portion of the diagnostic information from the embedded controller. In addition, the controller assesses the at least a portion of the diagnostic information to develop health information. The assessment involves evaluating the information related to the number of malfunctioning pixels.

Apparatus for controlling the thermal uniformity of a substrate. In some embodiments, the thermal uniformity of the substrate is controlled to be more uniform. In some embodiments, the thermal uniformity of the substrate is controlled to be non-uniform in a desired pattern. In some embodiments, an apparatus for controlling thermal uniformity of a substrate includes a substrate support having a support surface to support a substrate thereon. A plurality of flow paths having a substantially equivalent fluid conductance are disposed within the substrate support to flow a heat transfer fluid beneath the support surface.

摘要:
A copolyimide nano-fiber non-woven fabric, a process for producing the same and the use thereof. The process comprises the following steps: tetracid dianhydride monomer and diamine monomer are polycondensated in the reaction medium of a high polar solvent under mechanical agitation to form a solution of a copolyamic acid; the copolyamic acid solution is electrostatically spinned under a high voltage electric field to give a non-woven fabric of a nano-fiber of the copolyamic acid; and then the non-woven fabric is imidized. The copolyimide nano-fiber non-woven fabric has features of a strong tear resistance, a high porosity, high/low-temperature resistances and excellent mechanical properties, etc., and can be used in battery membrane and capacitor membrane.
