mBeacon: Accurate, robust proximity detection with smart phones and smart watches using low frequency modulated magnetic fields
نویسندگان
چکیده
We describe a proximity detection method that leverages the internal magnetic field sensors in smart phones and smart watches to allow reliable, robust detection of proximity to predefined regions of interest within a 30-50cm radius. For marking the regions, low cost, unobtrusive, easily deployable magnetic field beacons have been implemented. We evaluate our system in 5 different use cases in semi-naturalistic lab experiments inspired by different application domains.

Robust Identification of Smart Foam Using Set Mem-bership Estimation in A Model Error Modeling Frame-work
The aim of this paper is robust identification of smart foam, as an electroacoustic transducer, considering unmodeled dynamics due to nonlinearities in behaviour at low frequencies and measurement noise at high frequencies as existent uncertainties. Set membership estimation combined with model error modelling technique is used where the approach is based on worst case scenario with unknown but...

متن کاملIntrusion Detection for Smart phone using Cloud
Smart phones have recently become increasingly popular because they provide “all-in-one” convenience by integrating traditional mobile phones with handled computing devices. Unfortunately these mobile devices are beginning to face many of the same security threats as desktops. Since smart phones software architecture is similar to the PCs software architecture, they are vulnerable to similar ty...
