In this paper, an indoor office locator system is developed. The product developed uses body sensors to detect incoming objects using indoor positioning tracking algorithm which run on a server application to guide the user in an office environment were designed and developed. It is shown that overall the final system allowed a partially blind user to navigate the office with relative safety and accuracy.
Biometric systems are important for access control and authentication in various application scenarios. Single biometrics can be selected for authentication, but a multimodal approach is typically more reliable. In this paper, a multimodal biometric authentication system is developed. It consists of wireless sensor nodes equipped with accelerometers and infrared cameras, which enable analysis of gait...
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...
In emergency situations such as fires in homes and offices, it is often the case where members of a response team (eg. firefighters) are not able to locate each other due to fire and smoke. It is desirable to have a system which is able to locate all personnel such that a team leader can monitor their location and to enable the firefighters themselves to know their proximity to other firefighters...
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...
This paper describes the work carried out on the implementation of a wireless sensor network that was created for a data center using the 6LoWPAN communication protocol which monitors power consumption readings at various nodes in the system. A direct current (DC) network controller was designed to distribute DC energy through the system and provide power to a data center load in future buildings...
Impulse radio ultra-wideband (IR-UWB) ranging and localization have recently received significant attention due to the high accuracy and precision. This high accuracy can be exploited for many location aware applications in a wide variety of environments. Although most research efforts have focused on location-aware applications for indoor or outdoor environments, there are other environments, such...
