Title: Etienne Castanie: Innovator in Premise Occupancy Detection
Introduction
Etienne Castanie is a notable inventor based in Tours, France. He has made significant contributions to the field of occupancy detection through his innovative patents. With a total of 2 patents, Castanie's work focuses on enhancing safety and efficiency in various environments.
Latest Patents
Castanie's latest patents include methods and apparatuses for detecting occupancy in closed spaces. One of his patents, titled "Premise occupancy detection based on CO2 gas concentration," describes a system that measures Carbon Dioxide (CO2) concentration to determine if a space is occupied. By establishing a Base CO2 Concentration (BCC) and an Average CO2 Concentration (ACC), the system can detect the presence of individuals based on changes in CO2 levels. If the Total CO2 Concentration (TCC) exceeds the sum of BCC and ACC, it indicates that a person is present. This technology can trigger alarms or alerts when occupancy is detected.
Another patent, "Premise occupancy detection based on smartphone presence," outlines a method for dynamically monitoring occupancy based on smartphones carried by individuals. This system utilizes an app that transmits unique identification to maintain a count of people entering or leaving a designated area. The occupancy level can help determine if the space's capacity has been exceeded, also generating alarms when necessary. These innovations have applications in various fields, including space monitoring in schools, fire evacuation, security, and more.
