  • Patent number: 11911996
    Abstract: Methods and apparatus for modulating light using a tunable light modulation device. The tunable light modulation devices comprises an elastomer structure including at least one elastomer layer, a compliant electrode network of conducting fibers arranged on a first surface of the at least one elastomer layer, a patterned electric conductor arranged on a second surface of the at least one elastomer layer opposite the first surface. The patterned electric conductor includes a plurality of individually-addressable sections, and the compliant electrode network is configured to compress the at least one elastomer layer in the presence of an electric field between the compliant electrode network and one or more of the individually-addressable sections of the patterned electric conductor to produce a voltage-dependent roughening of the at least one elastomer layer.
    Type: Grant

  • Patent number: 10679899
    Abstract: A method for producing a semiconductor device involves forming a first transistor having a silicon substrate and a gate, and forming a second transistor, having a germanium substrate, on top of the first transistor. The second transistor is formed by forming a first gate of the second transistor on top of, and electrically coupled to, the gate of the first transistor, bonding the germanium substrate to the first gate of the second transistor so that the bonding does not damage the first transistor, and forming a second gate of the second transistor on the germanium substrate.

  • Patent number: 10281069
    Abstract: Flange technologies are described for a flange comprising a first and second side. Each side may include a knife edge surface disposed circumferentially around a base surface and a periphery section disposed around the knife edge surface. The knife edge surface and the periphery section are effective to define grooves therebetween. The flange may include an alloy with a relatively high thermal conductivity and yield strength. The flange may include water channels to remove heat.
