Spatio-temporal bird's-eye view images using multiple fish-eye cameras

In camera images for urban search and rescue (USAR) robots teleoperation, it is important to reduce blind spots and get surroundings as much as possible because of safety requirements. We propose a method to create synthesized birds-eye view images from multiple fish-eye cameras as spatiotemporal data which can reduce blind spots. In practical use, it is very important to get images robustly even when some troubles such as camera broken and network disturbances occur. This method develops showing birds-eye view images robustly even if some of images are not acquired by compensating past stored spatio-temporal data to these images. Effectiveness of the proposed method is verified through experiments.

P-73: Reflective Color LCD Composed of Stacked Films of Encapsulated Liquid Crystal (SFELIC)

A reflective color liquid crystal display (LCD), which dose not consume power for backlighting, is a key device for portable information equipment. A novel structure for three-layered guest-host (GH) liquid crystal displays (LCDs) has been proposed. The structure, called stacked films of encapsulated liquid crystal (SFELIC), has no intermediate substrates, and is expected to realize low cost and high brightness while eliminating parallax.

A reflective tri-layered guest-host color TFT-LCD

— We have developed a new reflective tri-layer color TFT-LCD with CMY guest-host LC materials. Optical improvements and optimization have resulted in high reflectance and good color image. We have shown that the tri-layer structure has high feasibility for bright color LCDs.

A high aperture and high density a-Si TFT-LCD with a new pixel structure

The authors have developed a TFT-LCD with new pixel structure which enhances aperture ratio. The new structure has a transparent electrode between the signal line and the pixel electrode, which shields the capacitive coupling between the signal line and the pixel electrode and reduces the liquid crystal disclination lines caused by the transverse electric field between them. A high aperture ratio of 40% has been achieved on a 40 /spl mu/m square pixel, which is the largest value for this size of a-Si TFT-LCD.<<ETX>>

53.5L: Late-News Paper: Reflective Electromechanically Actuated Film Display (AFD) for Direct Viewing

A novel electromechanically driven actuated film display (AFD) has been developed for direct viewing. It is comprised of mobile cantilevers supporting black, white or colored tabs which can be moved through applied voltage pulses. It possesses hysteresis characteristics for simple matrix driving and can offer features such as a low power-consumption, a paper-like white appearance and a full color performance.
