Digitally Controlled Power Supply
By Brian Steggall
This project is based on the concept of wanting an automated calibration system. In order to test various aspects of a particular product you must be able to supply a near constant voltage at a variety of values to determine the accuracy within. This design requires approximately 0 to 40 VDC, rated at about 4 amperes. The device needs to communicate to a computer via a RS –232 or IEEE 488 connection. Also a digitally controlled, as well as a manual, on/off switch must be implemented. The entire system must be maintainable and easy to calibrate. The system will probably be incorporated into many test procedures, but first it needs to be designed, built and tested and that is my goal. |

Central Patient Monitoring Unit (CPMU)
By Matthew Voigt, Aaron Jacobs, Hiap Weng Eng
In patient care facilities across the country, many patients are subjected to monitoring by means of stationary equipment, usually located in their rooms beside their beds. However, the mobility of these patients is very restricted by the mobility of the equipment itself simply because patients cannot venture far from their rooms without proper nursing attention. Since there is a major nursing shortage in all areas of the USA, many patients are not getting the proper monitoring and attention that they need. In order to help patients and nurses at the same time with this problem, we propose the Central Patient Monitoring Unit (CPMU). The CPMU will allow patients to be more mobile with less hassle and with continuous monitoring from nurses. It will allow nurses to monitor patients more easily and effectively from one station. This system is composed of two main components: a Wireless Transmitting Module (WTM) which is attached to the patient, and the Central Patient Database (CPD), which is located at the nurse’s station. |

Audio Amplifier with Digital Effects
By Rajendra Acharya, Tapas Neupane
Audio guitar amplifiers are easily available in the market, however they are exorbitantly priced. Guitarists also use effects such as echo, chorus, flange and distortion to process their guitar signal. The cost of purchasing such effects is not reasonable either. Novice guitarists, thus, are deterred from purchasing quality amplifiers and effects. Low noise audio amplifier with built in digital effects using a microcontroller can be built at much lower cost. To create the digital effects, however, lot of data memory is needed. Thus, using either a digital signal processor chip or a fast microcontroller with lots of data memory, digital effects can be created. Thus, a low cost low noise power amplifier with digital effects can be designed and built at a much lower cost than the amplifiers that are available in the market. |
