  • Publication number: 20130052449
    Abstract: A method for controlling density, porosity and/or gap size within a nanotube fabric layer is disclosed. In one aspect, this can be accomplished by controlling the degree of rafting in a nanotube fabric. In one aspect, the method includes adjusting the concentration of individual nanotube elements dispersed in a nanotube application solution. A high concentration of individual nanotube elements will tend to promote rafting in a nanotube fabric layer formed using such a nanotube application solution, whereas a lower concentration will tend to discourage rafting. In another aspect, the method includes adjusting the concentration of ionic particles dispersed in a nanotube application solution. A low concentration of ionic particles will tend to promote rafting in a nanotube fabric layer formed using such a nanotube application solution, whereas a higher concentration will tend to discourage rafting. In other aspects, both concentration parameters are adjusted.

  • Patent number: 8330693
    Abstract: A two-stage drive waveform switches a DFLC from a high tilt state to a low tilt state quickly and without scattering. A relaxation voltage is applied to delay the onset of the high amplitude high frequency kick voltage when switching from a high tilt state to a low tilt state. The relaxation voltage allows the molecules to ‘relax’ in accordance with their own elasticity towards their low tilt state in the direction of the average azimuth angle of the low tilt state. The kick voltage is then applied to drive the molecules quickly to the low tilt state. Optimal switching time and the desired molecular response is achieved by delaying the onset of the large kick voltage via application of the relaxation voltage. The relaxation voltage may constitute a lower amplitude holding voltage, a small or zero DC voltage or a smooth windowing of the kick voltage.

  • Publication number: 20120221291
    Abstract: An indoor testing device for multiple rotor-containing flying objects including a main support having a plurality of linking members, a plurality of mechanical arms, a plurality of trays, and control units of the mechanical arms. The main support is disposed vertically. The mechanical arms are separately disposed on the linking members of the main support with different height. The trays are separately disposed on one end of the mechanical arms for receiving rotor-containing flying objects, and the control units are disposed on the mechanical arms and rotate therewith. The device can be used for the cooperation and coordination test of multiple rotor-containing flying objects and autonomous control experiments of a single rotor-containing flying object. The tests have high stimulation and improve the usability of the experimental results in the actual system.

  • Publication number: 20120117493
    Abstract: A dashboard application can enable a user to quickly view data (and, in a particular aspect, data from one or more business applications) in an efficient manner. The dashboard application can be used to view data about one or more metrics that reflect the performance of a business, as derived from data maintained (perhaps in an associated data store) by the business application(s). In an aspect, a user can select two or more metrics to be displayed on a summary page and/or can invoke a detail page to view detailed information about one of the two or more metrics.

  • Publication number: 20120056149
    Abstract: Methods for adjusting and/or limiting the conductivity range of a nanotube fabric layer are disclosed. In some aspects, the conductivity of a nanotube fabric layer is adjusted by functionalizing the nanotube elements within the fabric layer via wet chemistry techniques. In some aspects, the conductivity of a nanotube fabric layer is adjusted by functionalizing the nanotube elements within the fabric layer via plasma treatment. In some aspects, the conductivity of a nanotube fabric layer is adjusted by functionalizing the nanotube elements within the fabric layer via CVD treatment. In some aspects, the conductivity of a nanotube fabric layer is adjusted by functionalizing the nanotube elements within the fabric layer via an inert ion gas implant.

  • Publication number: 20110001896
    Abstract: A two-stage drive waveform switches a DFLC from a high tilt state such as above the LC's linear region or near the ‘saturated’ or ‘field-driven homeotropic’ state of the LC to a low tilt state quickly and without scattering. A relaxation voltage is applied to delay the onset of the high amplitude high frequency kick voltage when switching from a high tilt state to a low tilt state. The relaxation voltage allows the molecules to ‘relax’ in accordance with their own elasticity towards their low tilt state in the direction of the average azimuth angle of the low tilt state. Once the tilt angle has relaxed sufficiently, the kick voltage is applied to drive the molecules quickly to the low tilt state. Most unexpectedly, optimal switching time and the desired molecular response is achieved by delaying the onset of the large kick voltage via application of the relaxation voltage.

  • Publication number: 20100315567
    Abstract: A liquid crystal based broadband filter and imaging system for analyzing the polarization state of radiation. The filter includes four elements: a quarter wave plate; a 45° polarization rotator; a 90° polarization rotator; and a fixed polarizer. The first three of these elements are electronically switchable, allowing the user to select from any of the six possible polarization states. The switchable elements use multiple liquid crystal cells made from dual-frequency materials. A dual-frequency signal is used to activate and deactivate the various elements to achieve the desired state configuration. The dual-frequency signal drives the liquid crystal cells in and out of states, improving the overall switching time of the filter. The configuration of the liquid crystal cells within each of the filter allows broadband operation over most of the visible, infrared and ultraviolet spectra. The filter cycles through six configurations corresponding to the six polarization states of the incident radiation.
