There are many manufacturers of dot matrix LCD modules. However, most of these displaysare similar. They all have on-board controllers and drivers capable of displaying alpha numericsand a wide variety of other symbols (including Japanese "Katakana" characters). The internaloperation of LCD controller devices is determined by signals sent from a central processing unit(in this case, a CoolRunner-II CPLD).

This book explains many powerful PEAR packages for maximizing your PHP development productivity for accessing and displaying data, handling dates, working with XML and Web Services, and accessing Web APIs.
When working with mathematical simulations or engineering problems, it is not unusual to handle curves that contains thousands of points. Usually, displaying all the points is not useful, a number of them will be rendered on the same pixel since the screen precision is finite. Hence, you use a lot of resource for nothing!
This article presents a fast 2D-line approximation algorithm based on the Douglas-Peucker algorithm (see [1]), well-known in the cartography community. It computes a hull, scaled by a tolerance factor, around the curve by choosing a minimum of key points. This algorithm has several advantages:

Widely known as carputer, this system is designed for:
* calculating speed, fuel consumption, economy driving, e.t.c.
* displaying information about temperatures and controll Air Conditioning system in your car.*
* controlling other devices, like electrically opened windows.*
The system is based on ATMega MCU programmed in C language.
Design patterns are elegant, adaptable, and reusable solutions to everyday software development problems. Programmers use design patterns to organize objects in programs, making them easier to write and modify. C# Design Patterns: A Tutorial is a practical guide to writing C# programs using the most common patterns.
This tutorial begins with clear and concise introductions to C#, object-oriented programming and inheritance, and UML diagrams. Each chapter that follows describes one of twenty-three design patterns, recommends when to use it, and explains the impact that it will have on the larger design. The use of every pattern is demonstrated with simple example programs. These programs are illustrated with screen shots and UML diagrams displaying how the classes interact. Each of these programs is available on the companion CD-ROM and can be run, examined, edited, and applied.
JCommon is a Java class library that is used by JFreeChart, Pentaho Reporting and a few other projects. The library contains miscellaneous classes that support:
* configuration and dependency management code
* a general logging framework
* text utilities
* user interface classes for displaying information about applications
* custom layout managers
* a date chooser panel
* serialization utilities
JCommon is licensed under the terms of the GNU Lesser General Public Licence (LGPL) version 2.1 or later.
This application report discusses the design of non-invasive optical plethysmography
also called as pulsoximeter using the MSP430FG437 Microcontroller (MCU). The
pulsoximeter consists of a peripheral probe combined with the MCU displaying the
oxygen saturation and pulse rate on a LCD glass. The same sensor is used for both
heart-rate detection and pulsoximetering in this application. The probe is placed on a
peripheral point of the body such as a finger tip, ear lobe or the nose. The probe
includes two light emitting diodes (LEDs), one in the visible red spectrum (660nm) and
the other in the infrared spectrum (940nm). The percentage of oxygen in the body is
worked by measuring the intensity from each frequency of light after it transmits
through the body and then calculating the ratio between these two intensities.

WordCloud is a visual depiction of how many times a word is used, or its frequency if you will, within a given set of words. It does this by: reading in plain text, filtering out "stop words", counting how many times a word is used, and displaying results in a Squarified Treemap.
