  • Patent number: 10823717
    Abstract: A system for use in wirelessly monitoring a pipeline such as a natural gas pipe. The system includes a locator configured to wirelessly transmit power and a subsoil sensor marker located adjacent the pipe and configured to wirelessly communicate with the locator. The sensor marker includes a microcontroller, a memory module, a sensor configured to sense the presence of a gas, and a power module. The power module is configured to harvest a sufficient amount of the power wirelessly transmitted from the locator in order to operate the microcontroller to take a measurement via the sensor, save the measurement in the memory module, and wirelessly transmit the measurement to the locator.
    Type: Grant

  • Publication number: 20140132909
    Abstract: A transparent display is disclosed that includes a display screen. The display screen includes a first film that includes a first transparent conductor disposed upon a first transparent substrate and a second film that includes a second transparent conductor disposed upon a second transparent substrate. A first polymeric liquid crystal composition containing spacer beads is disposed between the first film and the second film. At least one of the first transparent conductor and the second transparent conductor is shaped, or at least one of the first transparent conductor and the second transparent conductor is patterned. Also, disclosed is a display system that includes the disclosed display screen and an illumination device for projecting light onto or through the display screen. Finally, a method of constructing a display screen is also disclosed.

  • Patent number: 8089604
    Abstract: A liquid crystal cell article includes a layer of liquid crystal material disposed between a first polymeric substrate and a second polymeric substrate. The first polymeric substrate includes a plurality of first parallel conductive traces extending in a first direction and disposed between the layer of liquid crystal material and the first substrate, and a first release liner disposed on the first polymeric substrate. The second polymeric substrate includes a plurality of second parallel conductive traces extending in a second direction orthogonal to the first direction and disposed between the layer of liquid crystal material and the second substrate. The first polymeric substrate further includes a removable portion that is separable from the first polymeric substrate with the first release liner to expose a portion of the layer of liquid crystal material or second parallel conductive traces.

  • Patent number: 7929106
    Abstract: A liquid crystal display is disclosed, including first and second opposing substrates separated by a cell gap. The cell gap has an inner liquid crystal region including a liquid crystal composition, an outer sealant region including a sealant that bonds the first and second opposing substrates together, and a void region between the inner liquid crystal region and the outer sealant region. The sealant may be a pressure sensitive adhesive. Also disclosed is a method of manufacturing the liquid crystal display. A liquid crystal display assembly including at least two light reflecting liquid crystal displays is also disclosed, wherein at least one of the displays comprises the liquid crystal display disclosed herein.

  • Patent number: 7648645
    Abstract: A pre-polymer/liquid crystal composition is disclosed and includes, a liquid crystal component, a photo polymerization initiator, and a polymer precursor component. The polymer precursor component includes at least, a silane monomer, reactive (meth)acryloxy monomer or oligomer, and an ester, urethane, or (meth)acrylate based polymer or oligomer, bearing one or more reactive (meth)acrylate groups. Methods of forming a bistable electro-optical device are also disclosed.
