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...

We present a new block cipher LED. While dedicated to compact hardware implementation, and offering the smallest silicon footprint among comparable block ciphers, the cipher has been designed to simultaneously tackle three additional goals. First, we explore the role of an ultra-light (in fact non-existent) key schedule. Second, we consider the resistance of ciphers, and LED in particular, to r...

Disclaimer: This research paper does not necessarily reflect the policy position of the Commonwealth Government. Adam Graycar Director This paper is timely, given that policing is currently going through a period of significant change in both operational tactics and organisational structures. New ideas in crime reduction and changes to shortand longterm policing strategies are underway. Intelli...

We will describe trends in the LED market and the consequences on the technical roadmap of LEDproducts. This will prescribe the focal points and direction of the upcoming manufacturing technologies. Two main trends are reinforcing at the moment. The first is an ongoing miniaturisation; the second one is the increasing number of power applications coming up due to higher chip efficiencies. INTRO...

The main objective of this research was to develop a methodology based on Drury’s [1] intermittent illumination model to directly measure individuals’ corrective reaction times, without the two methodology-related issues of Lin & Drury [2]. Six highly-practiced participants performed self-paced circular tracking tasks by using a modified LED monitor in a darkened room. While performing movement...

Among the non-linear loads used in household, Compact Fluorescent Lamps (CFLs) and LED lamps are becoming more widespread, while incandescent lamps are intended to be replaced by these types of lighting devices. LEDs and CFLs are significantly more efficient and economical than incandescent lamps, and are expected to be used in 100% of residential lighting in the future. As nonlinear loads, LED...

The paper begins by discussing various approaches to hardware specification and verification. The main emphasis is on using mechanical verification tools to assist the verification process. The case study is the verification of a seven-segment LED display decoder circuit design, in which two popular verification tools, HOL and PVS, are compared and evaluated.
