Multi-Slot BLE Raw Database for Accurate Positioning in Mixed Indoor/Outdoor Environments
The technologies and sensors embedded in smartphones have contributed to the spread of
disruptive applications built on top of Location Based Services (LBSs). Among them, Bluetooth Low
Energy (BLE) has been widely adopted for proximity and localization, as it is a simple but efficient
positioning technology. This article presents a database of received signal strength measurements
(RSSIs) on BLE signals in a real positioning system. The system was deployed on two buildings
belonging to the campus of the University of Extremadura in Badajoz. the database is divided
into three different deployments, changing in each of them the number of measurement points
and the configuration of the BLE beacons. the beacons used in this work can broadcast up to six
emission slots simultaneously. Fingerprinting positioning experiments are presented in this work
using multiple slots, improving positioning accuracy when compared with the traditional single slot
approach
A novel method for in-home Gait Speed estimation in Health Monitoring Using Bluetooth Low Energy
Ponencia presentada en: 22nd IEEE International Conference on Industrial Technology (ICIT), del 10 al 12 de marzo de 2021Gait speed (GS) is a crucial parameter in the
evolution and diagnosis of degenerative illnesses. Nowadays, it is
measured in clinical environments where it is impossible to keep
track of all patients due to the lack of resources. The development
of GS measurement systems for in-home environments could
solve this problem, but current methods present, at least, one of
these problems: they require expensive hardware, are intrusive
for the patient, or are imprecise. A novel method to measure
GS in these scenarios using Bluetooth Low Energy and smart
wearable devices is proposed in this work. The proposed system
is inexpensive, non-intrusive, and its precision is comparable
to the current state of the art methods. This system could be
commercialized as part of an in-home health monitoring system
El siglo XIX extremeño en el currículo de Historia de segundo de Bachillerato
Adaptación de los contenidos de la asignatura de Historia de segundo de Bachillerato a la realidad extremeña. Los objetivos del trabajo son: incorporar los contenidos de la Historia de Extremadura al currículo de segundo de Bachillerato, elaborar un texto didáctico para la impartición de la materia, experimentar en las aulas el texto y las actividades propuestas para comprobar su grado de eficacia y potenciar la utilización del entorno extremeño como recurso didáctico.ExtremaduraES
