A simple method was proposed to find the pressure fluctuations of binary systems of Geldart Group B particles under bubbling fluidized bed conditions. The pressure fluctuations of binary systems could be predicted from the pressure fluctuations of the individual particles component which comprised the binary systems for completely mixed and partially mixed systems. The predicted pressure fluctuations could be used to calculate the minimum fluidization velocity of the binary systems. The predicted and experimental values of pressure fluctuations and the minimum fluidization velocity of binary systems were in fairly good agreement.

Viewing angle-dependent color shift is one of the major drawbacks of liquid crystal displays (LCD). As the viewing angle increases, not only the luminance but also the color saturation reduces and compromises the image quality. In this paper, we characterize the viewing angle-dependent color shift of an LCD and propose a compensation method of adjusting the backlights and panel transmittance simultaneously. By increasing the panel transmittance, the color shift and luminance attenuation can be minimized. By increasing or decreasing the backlight intensity, the original luminance can be preserved or the power consumption can be reduced. Similar to previous approaches, the proposed method requires a video camera to capture the user's location for calculating the viewing angle. We have also implemented an emulator for reproducing the viewing angle-dependent visual effects.SID 07 DIGEST • 1069

A contingent field sequential display reduces chroma to inhibit saccadic color breakup on‐the‐fly when saccadic eye movement is detected by an electro‐oculogram (EOG) sensing circuit.
