Health Services Wireless System

By Evans Mburu and Derek Ganz

The purpose of this project is to design and construct a communication call light and emergency alert system. This system is an excellent solution for the St. Cloud health services department in their day to day operations while attending to their patients. This document presents an outline to our approach, reviews the requirements for the wireless call light system, and states the design processes taken to develop a successful end product. It shows all the steps taken towards the development of the product.

Pro Weather Station

By Yassmine Yessoufou, Yee Keat Ng and Keng Yuen Chong

The purpose of our senior design project is to build a professional weather station (P.W.S). The P.W.S. collects, stores, reads, and graphic weather data. The user can utilize the weather station as a stand-alone unit and browse basic data. An important characteristic of the P.W.S is that it will be made up of a user-friendly control panel. Plug and play USB communication features are also included. Finally, PC application software has been developed to display the weather data.

Remote Pro Window Blinds

By Deepak Wagle and Sharif Huda

The objective of our senior project is to design a user friendly window blind as a safe alternative to the existing window blinds available in the consumer market today with a main focus on handicap and elderly people. Though remote control blinds and shades are available in the market today our system will have additional features like programmable remote control with LCD display and soft touch keypad to make it more practical and easy to use. For example, a user can program the blind to open the shades during the day and close it in the evening, especially if they are out working long hours. Furthermore, our design will also have a base unit with LCD display and soft touch keypad that can control the blind in case there is a power loss in the remote control unit. The compact design will make it affordable and useful for home office, or business.

Multiple Child Monitoring System

By Sudip Sherchan and Prakash Upadhyaya

The objective of our senior design project is to design a user friendly multiple child monitoring system that will help parents keep an extra eye on their children. The system consists of one parent unit and two child units. The parent unit consists of a microcontroller, decoder chip, display unit (Liquid Crystal Display), soft touch keypad, alarm, LEDs (Light Emitting Diodes), receiver module and an antenna. It can be powered by AC (Alternating Current) outlet or DC (Direct Current) batteries. The child unit alerts the parent unit if the child unit is out of range or if it detects water. The range of this system is approximately 500 feet in an open ground. The child unit also alerts when the electronic lock is broken or the battery voltage falls below a preset voltage level. It is designed to be used in the backyard, park or camp site. The LEDs in the system indicates the distance between the parent unit and the child units.

Regenerative Power Motor Control System

By Daniel Jesberg, Glen Danielson, Gabe Selinger

The concept of the project was to alter and improve the electronic motor control system of a golf cart. Knowing that electric motors and electric generators are mechanically equal, it was decided to incorporate a system that would harness the power of an electric motor that is lost when the motor continues to rotate with electricity removed, and use that lost power to charge the batteries. A second benefit found to be possible with the new system was to control the current through the coils of the motor to provide a type of electric braking. A third and equally important part of the project was to improve the speed control of the golf cart. The existing system had discrete speed levels that prevented smooth transitions from one speed to the next. The golf cart would only drive at these discrete sped levels, and there was no mid range between two of the discrete levels.

Smart Parking System

By Timchan Bonkat and Peng Lei

This project is an automated parking management system. It is designed to reduce the amount of time spent in locating and parking a vehicle in a parking lot. The system employs a video camera and image processing techniques to detect the presence or absence of a vehicle. The information is then sent wirelessly to be displayed on display units that are strategically placed within the parking lot. The information displayed will include the number of parking spaces that are available and their positions. Some of the advantages of this system are that the system can utilize existing security infrastructure such as security cameras. It also gives the exact position of the available parking spaces unlike other systems that just give you the number of spaces available. Also, unlike other parking management systems that utilize sensors, this system requires no wiring.

Wireless Baby Music Mobile

By Pradyumna Kark and Anita Sedhain

Currently baby monitors and music mobiles are sold individually on the market. Our objective is to design a wireless baby music mobile system which combines features of baby monitoring system and music mobile. Our design consists of two units, a child unit and a parent unit. The child unit houses the music mobile, which also serves as a monitor by alerting the parent unit when baby makes noise. The parent unit has the feature of receiving the sound and can play a song or/and move a small motor with lights on top of the baby’s crib to distract/comfort the baby as a temporary solution until someone can get to the baby. Another characteristic of the child unit is the noise sensitivity control which detects comparatively high frequency sound which eliminates the possibility of picking every sound that baby makes. Unlike other monitor systems, we can download audio files into the MMC (Multimedia Card) and the LCD displays what song is being played.

Sensor Based UGN

By James Hennessy, Rob Nunn, Jeff Dukowitz, and Charles Wilson (Mechanical Engineering)

There are many situations in which humans are put in danger. Soldiers and police officers accept danger as part of their job. Soldiers have to deal with enemy soldiers, weather conditions, land mines, and various other elements. Police encounter hostage situations and armed felons. Making their job safer is the least we can do for those who keep us protected everyday. But what can we do to prevent injury or even death to our soldiers and police officers? Our solution is to build an unmanned ground vehicle or UGV which the user would control from a remote location away from the robot. The robot would be able to get a visual of the hazardous location, report environmental conditions, and if necessary immobilize any opposition. This would reduce the amount of danger that our soldiers and police officers are in by surveying the area before they infiltrate the position. The design requirements for the UGV are laid out by General Dynamics, our sponsor for the project. First it must be able to operate without a line of sight to the base station. In order to do this a video camera with the ability to pan, tilt, and zoom will be fitted on the robot. Second, the robot will operate at least 100 feet from the operator. A pair of high power transceivers will be used to send data to and from the robot. Also, for video, a video transmitter mounted on the robot will send video to the base. Also the operator will need to know where the robot is so a GPS unit will be mounted on the robot. Finally, in order to mark where we have been and as a means to disable any resistance found the robot will have a paintball marker mounted on the pan-tilt mechanism.

The wireless multi-purpose Traffic Count System

By Leye Bello, Faisal Ahmed and Kingsley Ekinde.

The project is a traffic count system for AMC. This system uses optical sensors placed at each door to detect when a person walks through it. This information is then channeled to a substation which does the necessary data manipulation before transmission via a wireless link to a central Hub that stores the information in a database that can be monitored by the administrator. The administrator will have the option of displaying or graphing the data from each remote entrance, and manipulating that information as needed. The system is capable of counting inbound and outbound traffic in a realistic manner to ensure a good estimate of the number of people that pass through AMC.
