Interrogation of FBG sensor by a smartphone

Optical Fiber Sensors Conference 2020 Special Edition, 2021
Smartphone-based interrogation of FBG sensor is reported for the first time. Setup consists of a smartphone and low cost off-the shelf available components: a section of DVD disk, razor blade slit and a 3D-printed holder. Smartphone flashlight LED was used as a light source, and FBG spectra were projected on the smartphone camera by a DVD disk.

Manoeuvre segmentation using smartphone sensors

2016 IEEE Intelligent Vehicles Symposium (IV), 2016
In this paper, we propose a classifier-based approach for driving manoeuvre recognition from mobile phone data. We introduce a driving manoeuvre classifier using Support Vector Machines (SVM). We investigate the performance of a sliding window of velocity and angular velocity signals obtained using a smartphone as features for our classifier. Principal

Practical driving analytics with smartphone sensors

2017 IEEE Vehicular Networking Conference (VNC), 2017
Sensing various driving behaviors, such as accelerations, brakes, turns, and change lanes — is of great interest to many applications, e.g., understanding drive quality, detecting road conditions, and more. Many such applications rely on using smartphone placed in a vehicle to collect such data for ease of deployment and use.

An Overview of the Capabilities and Limitations of Smartphone Sensors

International Journal of Handheld Computing Research, 2013
Few technical details are available about the various sensors embedded in modern smartphones, and what details are available can be hard to assemble and interpret by the broader technical community that uses these devices. Since the physical and electromagnetic aspects of the sensors' operation can significantly affect the analysis and use of their ...

Path Estimation from Smartphone Sensors

2018
Nowadays the knowledge about position is very important for localization based services. Thanks to knowing the position many services can be provided, such as information about people in our surrounding, firemen can be navigated during movement while rescue action, or just simply tracking position of different things in buildings.

Influenza surveillance and forecast with smartphone sensors

Computing, 2013
In this paper we introduce an influenza surveillance and forecast system (ISFS) that can track the proliferation of influenza and predict potential infections by analyzing smartphone sensor readings. While previous studies investigate social connectivity to deduce proliferation paths, we focus on the physical contacts of each individual that are the ...

Smartphone sensor data as digital evidence

Computers & Security, 2013
The proliferation of smartphones introduces new opportunities in digital forensics. One of the reasons is that smartphones are usually equipped with sensors (e.g. accelerometer, proximity sensor, etc.), hardware which can be used to infer the user's context.

Smartphone sensors as random bit generators

2014 IEEE/ACS 11th International Conference on Computer Systems and Applications (AICCSA), 2014
Finding good entropy sources, designing deterministic (pseudo) random number generators, or simply finding suitable non-deterministic random number generators are major challenges. The goal of this paper is to evaluate the use of three motion sensors present in smartphones as potential nondeterministic, true random bit generators (TRNG).

Verification and Validation of Smartphone Sensor Networks

2012
This paper introduces a subset of mobile wireless sensor networks, called smartphone sensor networks, where large numbers of smartphone devices cooperate to perform sensing tasks. While these emerging networks show high potential, little work has been done on design-time verification and validation to ensure that a designed system will meet the ...

Analyzing Elevator Oscillation with the Smartphone Acceleration Sensors

The Physics Teacher, 2014
It has often been reported in this column that smartphones are very suitable tools for exploring the physical properties of everyday phenomena. A very good example of this is an elevator ride. In addition to the acceleration processes, oscillations of the cabin are interesting. The present work responds to the second aspect.
