  • Patent number: 9793417
    Abstract: A three-terminal nano-electro-mechanical field-effect transistor (NEMFET) includes a source electrode, a gate electrode, a drain electrode and a nanoelectromechanically suspended channel bridging the source electrode and the drain electrode. The nanoelectromechanically suspended channel includes a moveable nanowire and a dielectric coating on a surface of the nanowire facing the gate electrode. A thickness of a gap between the nanowire and the gate electrode is determined by a thickness of the dielectric coating.

  • Patent number: 9690161
    Abstract: A diffraction grating comprises a liquid crystal (LC) cell configured to apply an electric field through a cholesteric LC material that induces the cholesteric LC material into a heliconical state with an oblique helicoid director. The applied electric field produces diffracted light from the cholesteric LC material within the visible, infrared or ultraviolet. The axis of the heliconical state is in the plane of the liquid crystal cell or perpendicular to the plane, depending on the application. A color tuning device operates with a similar heliconical state liquid crystal material but with the heliconical director axis oriented perpendicular to the plane of the cell. A power generator varies the strength of the applied electric field to adjust the wavelength of light reflected from the cholesteric liquid crystal material within the visible, infrared or ultraviolet.

  • Publication number: 20160103351
    Abstract: A phase retarder includes a liquid crystal cell and electrical switching circuitry. The liquid crystal cell contains electrodes and an active layer comprising liquid crystal material stabilized by a polymer network that is shaped by a blue phase using a washout/refill procedure. The electrical switching circuitry is configured to operate the phase retarder at a switching speed of less than 500 microseconds for both rise time and decay time, and in some embodiments is configured to operate the phase retarder at a switching speed of 200 microseconds or less for both rise time and decay time. The polymer network typically has pores of less than or about 200 nm. The liquid crystal material may be a nonchiral nematic liquid crystal material, a chiral nematic liquid crystal material, or a chiral smectic liquid crystal material. In some embodiments the liquid crystal cell does not include an alignment layer.

  • Publication number: 20150121182
    Abstract: A method for processing information comprises: receiving an information presenting request from a terminal device, the information presenting request comprising at least specified information and a target server identifier for identifying a target server for presenting the specified information; processing the specified information to obtain rich text format (RTF) information corresponding to the specified information; and sending a RTF information presenting request to the target server according to the target server identifier, the RTF information presenting request comprising at least the RTF information. In the present invention, the specified information is processed by a processing server to obtain the RTF information corresponding to the specified information, thus phenomenas such as system crash or halt caused by the terminal device processing the specified information are avoided, and resources of the terminal device are saved.

  • Patent number: 7858965
    Abstract: The present invention generally relates to nanoscale heterostructures and, in some cases, to nanowire heterostructures exhibiting ballistic transport, and/or to metal-semiconductor junctions that that exhibit no or reduced Schottky barriers. One aspect of the invention provides a solid nanowire having a core and a shell, both of which are essentially undoped. For example, in one embodiment, the core may consist essentially of undoped germanium and the shell may consist essentially of undoped silicon. Carriers are injected into the nanowire, which can be ballistically transported through the nanowire. In other embodiments, however, the invention is not limited to solid nanowires, and other configurations, involving other nanoscale wires, are also contemplated within the scope of the present invention. Yet another aspect of the invention provides a junction between a metal and a nanoscale wire that exhibit no or reduced Schottky barriers.

  • Publication number: 20090227107
    Abstract: A network element (10), such as a Packet Data Serving Node, detects (31) a change in operational status of a mobile station during a communication session and, in response to detecting such a change, automatically increases (32) memory capacity as is available to support additional communication sessions while simultaneously persisting at least some session information for potential subsequent use during the communication session. For example, this response can occur upon detecting that a mobile station has changed from an active to a dormant status. Then, upon returning to an active status, the network element can use the persisted information to facilitate rapid reconstruction of infrastructure support for the mobile station's call participation.

  • Publication number: 20060146270
    Abstract: An LCD device (10) includes a first substrate (22), a second substrate (21), and a liquid crystal layer (23) including bend-aligned liquid crystal molecules interposed between the first and second substrates. The liquid crystal display device operates in an optically compensated bend (OCB) mode. The LCD device includes a plurality of pixel regions defining reflection and transmission regions (232, 231). A thickness of the liquid crystal layer in the reflection regions is less than a thickness of the liquid crystal layer in the transmission regions. Preferably, the liquid crystal display device further includes quarter-wave plates as first upper and lower retardation films (521, 511) disposed at outer surfaces of the first and second substrates. This ensures that the LCD device provides a quality display image and that its liquid crystal molecules can be realigned in a very short time upon a change in the applied electric field.
