Abstract: An ad hoc network organizational method which is employable with a collection of plural nodes in a setting where there is available a current overall network topology map containing at least the identities of, and the inter-nodal communication link qualities and capabilities associated with, each of the nodes. The method generally involves the steps of (a) examining the topology map to determine the current pattern of possible and not-possible direct communication links between pairs of nodes, thus to detect, from an inter-nodal, inter-communication point of view, hidden nodes and non-hidden nodes, and (b) on the basis of such examining, establishing a proxy networking scheme wherein pairs of nodes which are hidden with respect to one another can nonetheless communicate with one another through at least one, intermediary, selectable proxy node which is non-hidden with respect to each of the two nodes in such a pair.

Abstract: An autostereoscopic display comprises a pixellated transflective spatial light modulator which is arranged to provide a visual indication to an observer of the amount of crosstalk caused by reflection of ambient illumination. The display comprises a rear parallax barrier between a backlight and the modulator. Part of the barrier is formed as a screen blocking transmitted light from a first region of the modulator so that the pixels in this region are visible only by reflection of ambient illumination. In a second region, the pixels are illuminated with both transmitted and reflected light. A controller sets the pixels of the first region to maximum intensity and the pixels of the second region to a fraction of the maximum intensity. The fraction corresponds, for example, to a maximum amount of crosstalk which is permissible for autostereoscopic viewing.

An optimal partition of the first set of matrices is determined. A third matrix is formed. The third matrix represents a cross-correlation of a second matrix and each of the plurality of first matrices. A minimum corresponding to the first set of matrices is set. The second matrix is updated using the minimum corresponding to the first set of matrices. Each column of the second matrix is scaled by a first value.

Abstract: In a lighting device for a display device, sensor output determination portions determine whether color sensor output signals are greater than or equal to a predetermined threshold. Variable gain amplifiers amplify the color sensor output signals with a predetermined gain. A color control portion performs color control based on post-amplification signal and obtains luminances of three types of LEDs. Constant current circuits and the PWM circuits drive the three types of LEDs in accordance with control from the color control portion. Gains of the variable gain amplifiers are switched in a stepwise manner so as to become higher as the color sensor output signals become lower. Thus, it is possible to perform color control with high accuracy even when darker light is provided.

The information display device has the display screen with a touch sensor, and enables a remote control of the display screen through a touch operation on the small screen area which is set to display a demagnified version of an image displayed on the display screen, by shifting a touch operation position in the small screen area to a position on the display screen. Hence an operation on the display screen and that on the small screen can be executed as the operations corresponding with each other.

Abstract: A display device includes a display panel and a parallax barrier bonded together with an adhesive layer made of a light-curing resin (for example, ultraviolet curing resin). The display device allows 3D display or multiple-image display. The parallax barrier includes a pattern-formed light-shielding layer on barrier glass. The parallax barrier has an area that does not include the light-shielding layer on the periphery portions thereof. Thus, with the display device including the parallax barrier and the display panel bonded together, peeling on adhesive planes of the parallax barrier and display panel is less likely to occur.

Each module substrates can be reduced in warping or deformation after a blanking process. In addition, each module substrate can be formed thin since bending due to its own weight is small. Consequently, the substrate as a whole and the backlight can be formed thin.

Abstract: Paper (41) on which a first reference image (31) is formed in an image forming section (300), and a correction instrument (1) on which a second reference image (33) is formed, are placed at predetermined positions on an original platen (210). Reference images (31, 33) are read as an image for correction by an image reading section (200). An error in the image reading section (200) is measured based on the second reference image (33) of the correction image. The first reference image (31) of the correction image is used to remove the error in the image reading section (200) from the measured error, resulting in an error in the image forming section (300).

A photodiode and a first transistor are provided in series between the ground and a drain of each of pixels, and a signal corresponding to a current or electric charge generated in the photodiode in accordance with an optical input is outputted from a detection node located between the photodiode and the first transistor. A control part executes control to alternately repeat a logarithmic operation period during which a photoelectric conversion signal logarithmically converted by setting a gate voltage ?R of the first transistor to a first level is obtained and a linear operation period during which a linear type photoelectric conversion signal is obtained by setting the gate voltage ?R of the first transistor to a second level.

Abstract: A display element 1, provided at each point of intersections of a plurality of signal lines and a plurality of scanning lines, includes an optical modulation element 5 and an active element 2, wherein, when a scanning is carried out not less than once in one field period at a predetermined intervals, a memory element 3 which can store M-bit (M?1) information at the maximum is provided so that the optical modulation element 5 keeps the display with 2M-level gray scale until the next scanning. On this account, it is possible to supply gray scale signal data Dm to the optical modulation element 5 so as to keep the display condition, without attenuating the data after the scanning of pixels. Moreover, since the level of the gray scale display is kept by outputting the information stored in the memory element 3, the gray scale level in each time division sub field can be in concordance with the number of memory bits.
