TCL 3-D TV, sans glasses

TCL Corporation has recently showed its 3-D TV technology that doesn’t require glasses on the CES convention. The Chinese company made the first no glasses required set in order to solve the problem with 3D glasses which include headaches, eyestrain, and nausea. It is a 42-inch TD-42F and sells for about $20,000. TCL 3DTV Project Marketing Manager King said that it is already on the market in
China.

This 3-D technology adds a layer rippled lenses to the front of the TV screen to produce the three-dimensional effect. These could also be used in the home as well as on billboards. How does it work? There are actually eight lenses on the screen itself. You see only a few of those perspectives depending on where you stand in relation to the TV. The TCL’s TV set only displayed animation on the show floor. Review says that the 3D aspect of the screen did not “pop” forward as much. Well, it is better to see it yourself.

Blio e-reader at CES

The recently ended CES presented the Blio e-reader software application that can turn any laptop, netbook or smartphone into an image-rich, and full-color electronic reader. Blio E-Reader is free software that makes eBooks like you have never seen before. Because of its brilliant 3D, stunning and full-color pages come alive. Moreover, it uses publishers’ original PDF files to preserve the exact format of books and magazines while supporting interactive multimedia, including video and Web links. Now, everyone can enjoy a vast selection of cookbooks, travel guides, how-to books, schoolbooks, art books, children’s stories, and magazines.

Quasi-Periodic Steady State Analysis

I have learned that there are many ways to get the IP3 (input referred 3rd order intercept point) such as using the transient and DFT method, and the QPSS or quasi-periodic steady state analysis. It's my first time to use; I found it easy and interesting though.

How to use the QPSS? Using Virtuoso Analog Design Environment, here are the things to be set up:

1. First, make a test circuit creating 2 voltage source with frequency 1 and frequency 2 for the positive and negative input of the amplifier. For my analysis, I've used f1=98MHz and f2=100MHz. Of course, I should have the same amplitude for my 2 signals.

2. Engine setting is shooting.

3. Conservative is used for accuracy.

4. Pre-determined Sweep Range for the input signal. For example from 60dBuV to 120dBuV.

5. For the sweep type, I usually use the linear type with step size of 2.

Saving the netlist and running the program results to the following graph:
