In recent years, there has been growing interest in secure pairing, which refers to the establishment of a secure communication channel between two mobile devices. There are a number of descriptions of the various types of out-of-band (OOB) channels, through which authentication data can be transferred under a user’s control and involvement. However, none have become widely used due to their la...

The paper presents a combined experimental and theoretical study to determine the actual dynamic Young’s modulus (Edynamic) for the mechanical structure of a silicon microaccelerometer. The resonance (natural) frequencies of the suspension arms of accelerometer were measured using MSA-500 Micro System Analyzer and, then, introduced in analytical expressions in order to find Edynamic. The obtain...

For development of more convenient and useful applications, context-awareness has long been studied. This paper introduces an Android app that detects the current location, moving status, and watching status of the visitor. Our app investigates accelerometer values in order to determine moving status. With the accelerometer and orientation values our app determines the current location and watc...

Physiological data acquired during ambulatory health monitoring are affected due to physical movements of limbs. Thus making it important to know about limb movements. We propose a design of a system that can sense the limb movements using several 3-axies accelerometer sensors. The accelerometer sensor signals are acquired in digital form through a programmable system on chip (PSoC) and stored ...

This paper presents the design of a mechanical transducer for a new kind of optical-fiber accelerometer based on birefringence variation. Vibration-induced fiber deformation modifies the birefringence within the fiber and hence the state of polarization of the light. To deform the fiber a mechanical transducer has to be made. This article compares analytically different transducers using either...

This paper is devoted to accelerometer based image stabilization for general video based security surveillance systems. At the beginning an introduction to the image stabilization is presented. Short description of the actual state of common algorithms for image stabilization follows, including our solution with some partial optimizations. At the end, we present a suitable hardware platform hav...

The paper discusses results of experiments carried out at healthy individuals with an aim to establish an in-house developed sensor mechanism using ADXL 330 accelerometer. The sensor was developed in view to measure gait phases (heel strike & toe off), gait duration and gait speed. These findings were useful in understanding the range of normal gait though accelerometer and further used for con...

A simulation model for a two degrees of freedom industrial manipulator where an accelerometer is attached to the robot arm is presented. An overview of the kinematic and dynamic models as well as a thorough description of the accelerometer model are given. The simulation model can be run with di erent types of properties, e.g. model errors and disturbances. Di erent types of suggested simulatio...

the monitoring of epileptic seizures is mainly done by means of eeg (electroencephalogram) monitoring. although this method is accurate, it is not comfortable for the patient as the eeg-electrodes have to be attached to the scalp which hampers the patient’s movement. this makes long term home monitoring not feasible. in this paper the aim is to propose a seizure detection system based on accele...

Motorsports recognizes the need for a triaxial accelerometer that can provide accurate vibration results in pre-race trials, and real-time measurements during the course of an actual race. Precise data needs to be gathered that allows the racing engineer to determine design modifications and suspension adjustments when fractions of a second can determine the winner. Measurement Specialties, Inc...
