Definitions

  • the pair of electrodes instead of being on one side, e.g., on the top side of the piezoelectric material, may be on both sides, e.g., to sandwich the piezoelectric material. In this case, voltage is provided across top and bottom electrode pairs.
  • a sensor array can form or steer a beam that can cover a 360 degree space around the region
  • Embodiments including a flexible array of transducers of any type of transducer may be realized, such as ceramic piezoelectric elements, and/or thin film transducers, for example. Piezoelectric material may be used for both generation/transmission and reception/detection of ultrasound.
  • FIG. 5 a method for tracking activity in the presence of light dispersive media is illustratively depicted.
  • an area where light through air in the area is at least partially attenuated due to particulate matter is ultrasonically swept by employing an ultrasonic transducer array to scan the area to determine human activity or the presence of objects or animals.
  • the activity in the area is mapped to create an activity map. This may include, in block 506, that the area may be divided in to regions or portions. In block 508, activity for each region may be mapped.

Abstract

La présente invention porte sur un système de suivi (100), et sur un procédé correspondant, dans des zones comprenant un milieu dispersant la lumière, lequel système comprend un réseau de transducteur (20) placé au niveau d'une zone désignée (10) et configuré pour effectuer un balayage ultrasonore de la zone. Le réseau de transducteur est apte à déterminer la présence et la position de personnes, d'animaux ou d'objets dans la zone conformément au balayage ultrasonore. Un dispositif de commande (14) est configuré pour recevoir des résultats du balayage et créer une carte (30) de la zone. Un module d'action (25) est configuré pour recevoir un signal de commande provenant du dispositif de commande. Le signal de commande est envoyé au module d'action conformément à des informations de densité tracées sur la carte de sorte que le ou les modules d'action sont activés par le signal de commande conformément à la carte.
