Infocus LP540 (http://rbi.ims.ca/3860-546). Even the best PowerPoint presentation can suffer if the projector is mounted at a sharp angle producing a distorted image called the keystone effect. Besides having several features including front, rear, and ceiling projection methods, InFocus LP540 projector uses an Analog Devices iMEMS accelerometer to accurately measure the projection angle in any given setting. The accelerometer provides the tilt angle data to the Digital Keystone Correction software in the controller, which automatically determines the level of correction necessary (up to ±25 degrees) to digitally resize the image and provide a square and undistorted image.

Notepad Computer Knows Which Way is Up
Toshiba Portégé M200 (http://rbi.ims.ca/3860-550). The graphics capability of the M200 Tablet PC allows a speaker to add hand-written notes or diagrams to a document during a presentation or meeting—so long as the computer knows which side is up. By integrating a low-cost, compact, dual-axis accelerometer into the design, engineers made it possible to determine the orientation. The tilt input from Analog Devices'±2g, accelerometer also allows users to view the top and bottom of a web page by simply tilting the computer up and down. Tilting the notebook from left to right while viewing an eBook or digital magazine automatically turns the page, thanks to the signal from the accelerometer.

Self-Orienting Camera Phone
The V401D by Mitsubishi Electric (http://rbi.ims.ca/3860-548). Engineers at Mitsubishi realized it would be great to know which side of a cell phone is up when taking photos with it. To distinguish the portrait from the landscape mode in their 2G cell phone handset with integrated camera, they selected a low-g CMOS-based MEMS accelerometer to sense tilt. In addition to sensing the phone's position, the accelerometer made possible a pedometer feature to count the steps and measure the distance traveled. In the future, engineers plan to use it as an input for games. Unfortunately, the V401D is currently available only in Japan.

Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
