Algorithms for Detecting Motion of a GSM Mobile Phone
نویسندگان
چکیده
In this paper we detail two algorithms for detecting that a GSM mobile phone is moving (or stationary, since this is when the phone is simply not moving). These algorithms, in early experiments, show excellent promise and require nothing from the mobile phone other than radio signals that the phone must have to perform its normal function. We also discuss our approach to determine not only if a phone is mobile but also to differentiate motion based on walking from motion caused by traveling by car.

The Ability of GSM Mobile Phone Users in Detecting Exposure to Electromagnetic Fields and the Bioeffects of These Fields on their Vital Signs
Background & Aims: Since previous studies on complications resulting from exposure to electromagnetic fields emitted by mobile phones are based only on self- reported symptoms, this study was performed to find the capability of users in recognition of real/ sham microwave exposure and probable alterations of vital signs after microwave exposure. Methods: In a two- step screening, from 700 stude...

The Effect of Pre-exposure to Radiofrequency Radiations Emitted from a GSM Mobile Phone on the Suseptibility of BALB/c Mice to Escherichia coli
Background: Pre-exposure to radiofrequency radiations of mobile phones would significantly increase the survival rate of exposed animals compared to those exposed to a lethal dose of gamma radiation alone. Stimulation of the immune system is believed to be a key mechanism for the induction of this phenomenon, the so-called “adaptive response.†The immune system protects organisms against in...
