Abrégé

Systems and methods of using wireless signals to create a sensing infrastructure for tracking the location of a moving subject within residential or industrial indoor environments are provided. The changes and disruptions of wireless signals transmitted and received by a plurality of wireless devices are collected and analyzed to infer the position of a moving participant within a sensing area. More particularly, a proximity-based method that models and estimates the location of a moving participant within the sensing area with respect to a single or plurality of fixed position(s) of wireless devices is provided.

Classes IPC  ?

• H04W 64/00 - Localisation d'utilisateurs ou de terminaux pour la gestion du réseau, p.ex. gestion de la mobilité
• G01V 3/12 - Prospection ou détection électrique ou magnétique; Mesure des caractéristiques du champ magnétique de la terre, p.ex. de la déclinaison ou de la déviation fonctionnant par ondes électromagnétiques

Abrégé

An intelligent entrance detection system is provided where, primarily, any authorized or unauthorized entry to an area of a residential (or small industrial) unit covered by a wireless network is automatically detected from active off-the-shelf devices in that area. After the detection, an identification algorithm is employed to verify if this entry is a legal or illegal action. Based on this verification, either the routine smart home system is activated or a hazardous monitoring period begins to further investigate the suspicious event. If the illegal entrance is confirmed during the hazardous monitoring period, the owner of the property is informed through an intruder alarm protocol. In this invention, all of the analytic and processing steps, including entrance detection, owner identification, and device-free authority verification are designed based on monitoring and quantification of changes in surrounding wireless signals originated by human or object movements within the sensing area.

• G08B 13/00 - Alarmes contre les cambrioleurs, les voleurs ou tous intrus
• G08B 13/24 - Déclenchement électrique par une interférence avec la distribution d'un champ électromagnétique
