Development of Low Cost Private Office Access Control System (OACS)

Development of Low Cost Private Office Access Control System (OACS)

Over the years, access control systems have become more and more sophisticated and several security measures have been employed to combat the menace of insecurity of lives and property. This is done by preventing unauthorized entrance into buildings through entrance doors using conventional and electronic locks, discrete access code, and biometric methods such as the finger prints, thumb prints...

Development of Low-cost Gel Imaging System

In this paper, we proposed a method for configuring each component of a gel documentation system for the miniaturization and penetration of the system. To miniaturize the UV illuminator part, the minimum type of UVB lamp was adopted along with ballasts that can drive four lights. As the imaging system, a conventional compact digital camera, which has a similar performance to that of a DSLR, was...

Development of an electronic radiologist's office in a private institute.

A computer system that improves the quality, user-friendliness, accessibility, and management of radiology data (images, reports, databases, knowledge) was implemented at a private institute. A picture archiving and communication system (PACS) was integrated with the radiology information system (RIS). Two servers and 12 personal computers form the integrated system. The first server is dedicat...

A Low Cost Sensorless Control Drive Circuit for of Low Voltage Switched Reluctance Motor

Shaft position sensing is an essential part of switched reluctance (SR) motor drive In order to synchronize the pulses of phase current with the period of rising inductance of the proper motor phase. Direct sensors such as, Hall effect and optical encoder are commonly used in SR motors. The purpose of this paper is to present an indirect shaft positioning sensing known as "sensorless " control ...
