Simultaneous drone localization and communication using visible light

Drones that perform complex autonomous movements require a perfect estimate of their current position. However, internal measurement unit (IMU) errors introduce drift in this estimate, leading to significant discrepancies between the predicted and actual location. Various solutions have been proposed to calibrate the IMU, including methods...

Designing an adaptable and low-cost system for gesture recognition using visible light

This paper describes the design of an adaptable, low-cost, and energy efficient gesture detection system. The system leverages the ambient light available in the environment to perform Visible Light Sensing (VLS) using powerful Convolutional Neural Networks. The focus lies on designing a system that is capable of robust gesture detection in any...

Adaptive Real-Time PPG Signal Qualification and Pulse Segmentation

Ever since its invention in the 1930s, photoplethysmography (PPG) is a wide-spread technique used for health-monitoring. Via illumination of the human skin with a light source and capturing the light, an estimate of important physiological properties such as the heart rate can be made. This is commonly done with dedicated medical equipment, but...

Automating the Diagnosis and Quantification of Urinary Schistosomiasis

Schistosomiasis is a neglected tropical disease (NTD) that affects around a quarter-billion people worldwide. Most of the infected people live in tropical regions, especially in sub-Saharan Africa, where there is limited access to diagnostic and other relevant medical facilities. The current reference standard diagnostic procedure - conventional...

Monocular Visual Inertial Odometry for Underwater Vehicle Navigation, Optimized on Embedded System

Underwater robots are widely used in various operations below the surface of the sea. In many of these operations the precise localization and positioning is quite important, especially in cases that the robot must navigate between man-made installations. Although underwater vehicles can carry a number of different sensors, many of them can not...

Novel Interaction Method for UHF RFID Tags

RFID technology is slowly replacing traditional bar codes as a way to identify and track objects and individuals. However, consumer-oriented market penetration has been limited as dedicated RFID readers carry a high start-up cost. Furthermore, interactions with individual tags require special-purpose RFID readers. We present a novel RFID tag...

Indoor localization using thermal sensors

Locating people inside buildings is still an unsolved problem. There is a lot<br/>of research going on in this field and many different solutions using different<br/>techniques have been proposed. However, there is no widely accepted indoor<br/>localization solution like how GPS is for outdoor localization due to less accuracy, higher hardware...

OS evaluation for real time image processing on a multicore architecture

Traditionally embedded applications were limited to dedicated hardware with limited functionalities controlled by a microcontroller. With the advancement of technology and the rising needs embedded applications now run on Consumer off the shelf (COTS) products. Using general-purpose operating systems makes the development cycle for these...
