Wearable devices like smartwatches are becoming an accepted way to monitor a person's health stats such a heartrate and physical activity. This paper will explain how to develop a do-it-yourself (DIY), smart wristband to perform photoplethysmography (PPG), also known as pulse oximetry. The designed Pulseband acquires PPG signals and estimates heart rate (HR) in real-time. HR estimates can be transmitted...
The proliferation of mobile devices, ubiquitous internet, and cloud computing has sparked a new era of Internet of Things (IoT), thus allowing researchers to create application-specific solutions based on the interconnection between physical objects and the internet. Recently, wearable devices are rapidly emerging and forming a new segment-“Wearable IoT (WIoT)” due to their capability of sensing,...
Mobile phones are a ubiquitous and preferred communication, entertainment, and information access platform. Smartphones may provide an opportunity to better assess mood and behavior and to provide intervention timely, economical, rapid and effective intervention for those with mental disorders. This is an important target because behavioral health problems are associated with many of the medical disorders...
The ever-increasing popularity of online stores is reshaping traditional commerce models. In particular, brick-and-mortar stores are presently facing the challenge of reinventing themselves and their business models to offer attractive yet low-cost alternatives to e-commerce. Other industries have already introduced new concepts to fight inefficiency (i.e., “Just-in-Time” inventory management in Automotive),...
There is no consolidated, integral, quantifiable, granular, updated source of information for the roads we traverse and the environment we live in everyday. This leads to ambiguity about road conditions, which is tolerable during normal conditions but extremely problematic in adverse conditions such as snow blockages, water-logging due to storms, degraded roads and potholes. Without such knowledge,...
Modern vehicles with semi-autonomous (driver-assistance systems) and autonomous capabilities require sophisticated on-board and off-board diagnostics for safe operation, and to reduce unnecessary component replacements at the service garage. We present a diagnostic approach that strategically fuses different sources of instrumentation available in a time-triggered automotive network (Flex Ray) for...
Even though it might be beneficial to have continuous baseline data upfront, nowadays hospitalized patients are put on a vital signs monitor not earlier then they become bed-ridden. Aim of this study is to show the feasibility of a broader monitoring concept embracing many more subjects by monitoring contact-free vital signs with sensors embedded in clinical fitments. This work demonstrates a way...
Practical use of digital signal processors has dramatically increased over the last few years due to their versatility, computing power and decrease in price per MFLOPS. Consequently, growing interest of real-time DSP even for biomedical applications demands from BME students to come close up and personal with real DSPs during their studies. In order to do so, we implemented an earlier proposed lab...
