We present a System LCD with novel 3-dimensional input device for use in next generation mobile products. The 3D input function is formed by a directional image sensor integrated onto the display TFT substrate and is used to detect the location of multiple objects above or on the display surface. In order to prove the concept of this novel technology, a 2.6” VGA System LCD incorporating the 3D ...

The purpose of this research is to automatically segment and read visual code markers. These markers are found in standard 640x480 pixel color images that were acquired with standard VGA cell phone cameras. In this paper, we investigate an approach to automatically identify and read visual code markers. The experimental results show that the algorithm discussed in this paper successfully segmen...

An interactive Segmentation and Labelling Automatic Module (SLAM), especially developed for Windows-based Personal Computers, is described. The system is extremely user-friendly and it was designed with the aim of supporting speech scientists in assessing the very heavy and time-consuming task of segmenting a big amount of speech material such as that caused by the tremendous spread of new and ...

In this paper, a voltage mode variable gain amplifier (VGA) is presented. A fully differential implementation is used to suppress the common mode noise and increase the dynamic range. The gain of the proposed VGA can be digitally controlled from 0 to 53 dB, with a 1 dB resolution. The gain control is performed in two stages; coarse control with a 6 dB resolution and fine control with a 1 dB res...

This paper reports the design of a highly-linear CMOS amplifier for Variable Gain Amplifier (VGA) applications. A better than –60dB 3rd harmonic distortion at differential output level of 1V peak-to-peak is obtained by utilizing a linearization scheme that does not rely on the active devices. The amplifier maintains 3dB bandwidth over 300MHz. A noise figure at 8.6dB is obtained with source impe...

We previously reported several static three-dimensional (3-D) display implementations of the partial pixel architecture [J. Opt. Soc. Am. A 12, 73 (1995)]. We report herein our f irst real-time 3-D display based on this architecture. The display is functionally equivalent to a real-time holographic stereogram. It is autostereoscopic and provides horizontal motion parallax. The display device is...

The development of liquid-crystal panels for use in commercial equipment has been aimed at improving the pixel resolution and the display efficiency. These improvements have led to a reduction in the thickness of such devices, among other outcomes, that involves a loss in phase modulation. We propose a modification of the classical phase-only filter to permit displays in VGA liquid-crystal pane...

N-type AlxGa12xN exhibits a dramatic decrease in the free-carrier concentration for x>0.40. Based on first-principles calculations, we propose that two effects are responsible for this behavior: ~i! in the case of doping with oxygen ~the most common unintentional donor!, a DX transition occurs, which converts the shallow donor into a deep level; and ~ii! compensation by the cation vacancy (VGa ...
