  • Publication number: 20080290278
    Abstract: A circuit for implementing a registration-free, contiguous conductive plane. A circuit may include a plurality of conductive structures in a first plane. The circuit may further include a contiguous conductive equipotential surface in a second plane parallel to the first plane. The circuit may further include activation means configured to adjust an electric field between the first and second planes thereby activating one or more structures in the first plane by increasing a potential difference between the first and second planes to a threshold level deemed to constitute an active state. The circuit may further include deactivation means configured to adjust the electric field between the first and second planes thereby deactivating one or more structures in the first plane by decreasing the potential difference between the first and second planes below a threshold level deemed to constitute a deactivated state.

  • Patent number: 7450799
    Abstract: Enhancement of the contrast ratio of optical flat panel displays by integrating an array of corner-cube retroreflectors into the front face of the optical display, said integration involving mutual adaptation of both the display and the corner-cube retroreflector geometry to unite the two disparate optical systems. The light emission from the display passes through the truncated vertex of the corner-cubes to the observer. The display directs its emitted light through the vertex apertures (either as a natural behavior, or by interposing a registered array of light concentrators between the display and the corner-cube array). The improvement in contrast ratio arises due to the corner-cube retroreflectors' ability to direct incident ambient light directly back to its source, rather than the viewer's eyes. Ambient light reflections are not attenuated but maximized; this maximization is directed away from the viewer, causing the array to appear dark even in direct sunlight.

  • Patent number: 7449759
    Abstract: An electromechanical dynamic force profile articulating mechanism for recovering or emulating true parallel plate capacitor actuation behaviors from deformable membranes used in MEMS systems. The curved deformation of flexible membranes causes their MEMS behavior to deviate from known interactions between rigid plates that maintain geometric parallelism during ponderomotive actuation.

  • Publication number: 20080192065
    Abstract: A mechanism for mitigating undesired color image breakup artifacts arising in display systems that exploit the principle of field sequential color generation. By suitably reducing the time interval during which image information strikes the moving retina, such that the differential position for the respective red, green, and blue components of the image falling upon the moving retina does not exceed the diameter of a retinal cone or rod, the cause of the breakup is negated and the image becomes unitary as expected: the eye sees the image as if all the components arrived at the same time. The truncation of light emission into shorter time frames necessitates a compensatory increase in imaging light intensity, such that the net amount of photonic flux striking the retina, averaged over time, remains unchanged. The mechanism can be applied to systems with discrete red, green, and blue sources as well as to color-wheel-based systems.

  • Patent number: 7218437
    Abstract: A method and system for generating colors efficiently. In one embodiment, a start signal for a primary color subcycle may be received. A primary light source used to drive the primary color may be activated if there is data in the primary color's buffer. The primary light source may be deactivated during the primary color subcycle if there is no data in the primary color's buffer. In another embodiment, a highest amplitude signal for one of a plurality of primary colors may be normalized. A drive light source intensity may be adjusted to a percentage of a maximum intensity where the percentage corresponds to a content of the normalized primary color in a frame. The amplitude of all but the normalized primary color may be adjusted proportionally. In another embodiment, a maximum intensity for a light source intensity may be set to a first value. A maximum pixel intensity for each of a plurality of pixels may be set to a second value.

  • Publication number: 20070091011
    Abstract: A display system for presenting one or more planes of display information. The display system may include two or more display modules positioned in a spaced relationship in a stacked formation substantially along a Z-axis perpendicular to a display face of a display module. Each display module may be selectively activated to display a visual image or deactivated to a quiescent state. Further, when a display module is activated to display the viewed image, the viewed image can be viewed through a prior display module which is deactivated to a quiescent state.

  • Publication number: 20070047887
    Abstract: An optical noise reduction mechanism for reducing undesired frustration of total internal reflected light. Such optical noise may stem from defects in waveguide construction. Such optical noise may also stem from the difference in refractive index between any cladding layers disposed onto the planar waveguide and the refractive index of the medium (e.g., air) between the light sources and the light insertion surface of the planar waveguide. By interposing a material of appropriate refractive index, either as a thin layer onto the light insertion surface of the waveguide or filling the space between the waveguide and the light source, the planar waveguide becomes more tolerant of geometry errors and cladding layer properties because a safe operating area is established between the unadjusted critical angle of the system and the actual range of ray angles allowed admittance into the waveguide.

  • Publication number: 20060238443
    Abstract: An addressing mechanism for charging and discharging quasi-capacitive elements in an X-Y matrix. The addressing mechanism may be configured to toggle a resistor-capacitor (RC) time constant between large and small values such as by opening or closing a circuit path to a low impedance resistor disposed in parallel with a higher impedance in-line resistor. When this occurs, elements in the X-Y matrix can be addressed and controlled. The X-Y matrix may be comprised of multiple “rows” and “columns” of conductors where crosstalk may occur along the columns and rows. Crosstalk may be curtailed by using either hysteresis management or global control of the row's impedance along its entire length. The resulting control obviates the need for active devices at each matrix element to perform the switching functions.

  • Publication number: 20060061559
    Abstract: The encoding and processing of data for many applications can be rendered more tractable when the encoding method can independently manipulate two or more parameters that result, by conjunction, in an accurately posted data value precisely where it is expected. From a data standpoint, this would entail dividing an n-width digital word into separate fractional words and processing the subsets consecutively and independently, where the distinction between these fractional words has an explicit bearing on the information being borne. For example, an 8-bit word can be decomposed into two 4-bit words, half of which are processed while the transmission source is at full intensity, the other half being processed while the transmission source is at 1/16th intensity, thereby recovering the entire dynamic range of the original 8-bit word while reducing the bandwidth and cycle speed necessary for the transducer to be driven by the input signal.
