Fish conservation is a concern due to the impact of industrial fishing that causes overfishing. Fish farming has been an approach to fish conservation and systems are required to monitor ecosystems. This paper describes the design of a solar powered autonomous fish pond management system that can be used for fish conservation. The system consists of a floating node, equipped with sensors, that is...
Many vehicle accidents are caused by driver fatigue. Systems to monitor driver fatigue can contribute to a decrease in fatalities. This paper describes the development of a multi-sensor system for driver fatigue detection. The system achieves this by monitoring eye closure and wheel steering movements, and is able to alert the driver of any detected anomalies. Various techniques are suggested for...
Hazardous environments at the workplace are a significant contributor to injuries due to accidents as well as chronic diseases. There are many occupational health and safety (OHS) systems, but they are costly or not flexible. This paper presents a low-cost OHS. It consists of various sensors that can be used to monitor whether a safety helmet is being worn, the worker is mobile and safety boots are...
Electric shocks due to high voltage lines can pose serious health risks to workers. Reliable and efficient systems to alert workers of nearby live power lines are necessary. In this paper, a personal high voltage safety system with wear monitoring is designed and implemented. A wrist module which consists of an electric field detector and optical heart rate monitor is developed from first principles...
There is a persistent problem that continues to be a relevant demand for the chemical, oil, food and pharmaceutical industries, the fouling detection in ducts systems. This work shows the early tests to develop a platform for detecting fouling in pipes and analyze specific locations using the impact hammer test based on a wireless sensor network communication. To minimize the costs of maintaining...
This work describes the development of a mobile incident response system which can be used by public entities such as the police or municipality services to improve the assignment of response teams to reported incidents. It is also shown that the system can be easily integrated to augment current indoor air quality monitoring systems in future buildings. The system is based on the capability of smartphones...
This paper presents an overview of the work done so far related to the use of temperature sensors as performance monitors for RF and MMW circuits with the goal to implement built-in testing or self-calibration techniques. The strategy is to embed small temperature sensors on the same silicon die as the circuit under test, taking advantage of empty spaces in the layout. This paper reviews the physical...
Telemonitoring is a tool with proven results demonstrating clinical benefits in reducing mortality and hospi-talizations. In this context, heart rate and rhythm are vital signs of utmost importance for monitoring a patient's condition. Recent advances in mobile technologies have allowed smartphones to be of great usage in this scenario, given its processing power, connectivity capabilities, sensor...
A system for the interrogation of fiber Bragg grating (FBG) sensors using a strain-tuned EDF laser with linear cavity is described. An optical switch is spliced to one end of the laser cavity and connects one of two high-strength draw-tower fiber Bragg gratings (DTGs). The gratings are simultaneously tuned by a stretching device and act as the end reflector of the laser cavity. By applying a ramp...
