Optimum Number of Display Colors and their Chromaticity Regions for LED Traffic Information Board

Development of On-board Passenger Information Display

Kiaki Matsumoto Koji Nakada Kazuya Azuma Hiroshi Hatakeyama Tatsuya Tokunaga Kazunori Takahashi OVERVIEW: Advances in ICT and display panels in recent years have led to on-board passenger information displays becoming commonplace on commuter trains. Hitachi commenced serious development in 2006 with the development of an on-board passenger information display based on the concept of experience ...

Cockpit Display of Traffic Information Using GPS

This paper describes the need for, and the development of, an avionics device to provide cockpit display of proximate traffic. The device is targeted at general aviation (GA), and is designed to address the needs of this unique market; namely pilot utility and low cost. Traffic Alert and Collision Avoidance Systems (TCAS) are currently in use by the commercial airlines and are being installed b...

RS-232 Led Board

This article demonstrates how to develop a Microchip PIC16F84 based device that supports RS-232 interface with PC. Circuit (LED Board) design and software development will be discussed. PicBasic Pro Compiler from microEngineering Labs, Inc. is used for PIC programming. Development of LED Board Control Console using C/C++ is also briefly discussed. The project requires basic work experience with...

Optimized design for controlling LED display matrix by an FPGA board

The very important objective of the digital designer when using discrete gates for implement a Boolean function is to keep the number of used gates to a minimum and win a memory space without lost the original information. In this sense, the Simplification is very important and could be achieved by a purely algebraic process, but it can be tedious when it arrived to a very large number of varia...
