Govardhan Reddy Patancheru Wearable Heart Rate Measuring Unit


Master's Thesis from the year 2014 in the subject Electrotechnology, grade: A, Mid Sweden University, course: Electronic Design, language: English, abstract: Despite having the numerous evolved heart rate measuring devices and progress in their development over the years, there always remain the challenges of modern signal processing implementation by a comparatively small size wearable device. This thesis paper presents a wearable reflectance photoplethysmography (PPG) sensor system for measuring the heart rate of a user both in steady and moving states. The size and, power consumption of the device are considered while developing, to ensure an easy deployment of the unit at the measuring site and the ability to power the entire unit with a battery .The selection of both the electronic circuits and signal processing techniques is based on their sensitivity to PPG signals, robustness against noise inducing artifacts and miniaturization of the entire measuring unit. The entire signal chain operates in the discrete-time, which allows the entire signal processing to be implemented in firmware on an embedded microprocessor. The PPG sensor system is implemented on a single PCB that consumes around 7.5mW of power. Benchmarking tests with standard heart rate measuring devices reveal that the developed measurement unit (combination of the PPG sensor system, and inertial measurement unit (IMU) developed in-house at Acreo Swedish ICT, and a battery) is comparable to the devices in ...

Sabit Ekin, Aly I. RF-Based Location Determination In Heterogeneous Sensor Networks


Today, wireless sensor networks have become a key technology for different types of "smart environments", and an intensive research effort is currently under way to enable the application of wireless sensor networks for a wide range of industrial problems. The need for a cost-effective means for sensor localization eliminates a variety of options including GPS. Several approaches are available to determine the location of the sensor nodes. Most of these algorithms require extra hardware resulting in higher costs that is not feasible for large networks. In this book, an RF-based localization approach is presented that utilizes particle filters. Due to the availability cheap wireless transmitters with received signal strength indicators, the proposed approach provides an effective solution to the challenging problem of localization. A prediction algorithm is designed to overcome the complications caused by fast fluctuations in the received signal power due to the propagation channel. Particle filters are then utilized to estimate the position of the sensors. A major development that has been presented in this book leads to significant increase in the positioning accuracy.
