We developed a smart system consists of optimum number of wireless sensors that includes current, bed, and water flow sensors. The sensors provide information that can be used...
A prototype system has been designed to automate the use of a Cattle Feed Mixer with the aim of optimizing the efficiency, precision and consistency of the mix. Many additional nutrients are added into cattle feed at various times throughout their lactation cycle in order to produce optimum milk quantity and quality. Multiple herds also require various quantities of additional nutrients. At present...
There are many issues in designing and implementing an intelligent wireless sensor network based smart home for monitoring the elderly. The smart home is based on a few smart and intelligent wireless sensors, which can be configured around a wireless ad-hoc network. The system will generate early warning message to care giver, when an unforeseen abnormal condition occurs. The costs and risks associated...
A remote controlled robotic arm has been designed and fabricated for the purpose of remote monitoring of plant tissue growth in research projects conducted by Plant & Food Research Limited, New Zealand. The robotic arm consists of a light weight aluminum tubing with low voltage, high torque servo motors providing the movements for the various joints. The arm can swivel 180 degrees on its base...
Interdigital sensors have been successfully employed in various fields; in this paper we attempted to determine the looseness in sheep skins using interdigital sensors. Looseness is one of the quality attributes that determines the value of the leather. A low cost interdigital based sensing system with an effective data acquisition system has been designed.

This paper details a technique to significantly increase the speed of image processing for robot identification in a global-vision based system, targeted at real-time applications. Of major significance are the proposed discrete and small look-up tables for Y, U and V color thresholds. A new YUV color space has been proposed which significantly improves the speed of color classification and segmentation...
This paper presents the design of a low-cost physical parameter measurement device used to monitor useful parameters like heart rate, temperature, blood pressure, blood oxygen saturation, etc. of a human subject. These measurements are wirelessly transmitted to a receiver which sends out an alarm if any of these values are out of the expected predicted measurements. This device consists of a wrist...
This paper presents the design, implementation and test results of an online system for instantaneous measurement and display of fuel consumption in a vehicle. By utilizing the existing available sensors for input, the overall cost and complexity of the system is greatly reduced. The system is intended to help reduce the fuel consumption, thereby reducing the cost of running the vehicle. The instrument...
In this paper we present the design intricacies and implementation details of a novel selective activity monitoring (SAM) system targeted for homes for the elderly. The system is designed to support people who wish to live alone but, because of old age, ill health or disability, there is some risk in this, which worries their family or friends. The system works on the principle of using sensor units...

The virtual laboratory has allowed us to teach electromagnetics in a new and effective way, helping our students master this...
This paper details methods of solving problems that are encountered when human beings teleoperate robots. Special emphasis has been given to the ease of operation and some form of force sensation. Through the use of a rigid control rig, fitted to the user's arm, it is possible to easily control an anthropomorphic robot arm using a master-slave control methodology. The force being exerted by the arm...
This paper has described some initial work in developing a planar electromagnetic sensor for use in nondestructive evaluation (NDE) of saxophone reeds. Both theoretical and experimental approaches were undertaken. The results obtained serve as a starting point for development of a commercial sensor. This sensor has many different possible applications including quality inspection for dairy products...
This paper introduces a real-time image processing algorithm based on run length encoding (RLE) for a vision based intelligent controller of a humanoid robot system. The RLE algorithms identify objects in the image providing their size and position. A RLE Hough transform is also presented for recognition of landmarks in the image to aid robot localization. The vision system presented has been tested...
A method was developed for direct determination of minor and trace amounts of Cr, Mn, Cu, Ni, Co, Li, Pb, Cd, Bi, Sb, Be and Ag in silicate rock, lake and stream sediments using a microwave oven dissolution method and a multi-element graphite furnace atomic absorption spectrometer equipped with a Zeeman-effect background correction device.
