Title (EN) DETECTING MOTION BASED ON REPEATED WIRELESS TRANSMISSIONS
(FR) DÉTECTION DE MOUVEMENT SUR LA BASE D'ÉMISSIONS SANS FIL RÉPÉTÉES
Abstract: front page image
(EN)In a general aspect, motion of an object is detected based on wireless signals. In some aspects, wireless signals based on a repeated wireless transmission are received at a wireless sensor device in a space. The received wireless signals are analyzed, by operation of a processor, to detect movement of an object in the space. The analysis includes determining complex values representing the relative phases and amplitudes of respective frequency components of each of the received wireless signals, and detecting movement of an object in the space based on a change in the complex values.
(FR)Selon un aspect général, le mouvement d'un objet est détecté sur la base de signaux sans fil. Selon certains aspects, des signaux sans fil basés sur une émission sans fil répétée sont reçus au niveau d'un dispositif de capteur sans fil dans un espace. Les signaux sans fil reçus sont analysés, au moyen d'un processeur, pour détecter le déplacement d'un objet dans l'espace. L'analyse consiste à déterminer des valeurs complexes représentant les phases et amplitudes relatives de composantes de fréquence respectives de chacun des signaux sans fil reçus, et à détecter un déplacement d'un objet dans l'espace sur la base d'un changement des valeurs complexes.
