DOOR AND WINDOW CONTACT SYSTEMS AND METHODS THAT INCLUDE TIME OF FLIGHT SENSORS

摘要

Systems and methods that address the gap, security, and robustness limitations of known door and window contact systems and methods without increasing the overall cost thereof are provided. A system can include a time of fight sensor for mounting in or on a first portion of a window unit or a door unit, and a microcontroller unit in communication with the time of flight sensor. The sensor can measure a time for a signal to travel from the sensor to a second portion of the window unit or the door unit and back to the sensor, the sensor can transmit the measured time to the microcontroller unit, and the microcontroller unit can use the measured time to make a security determination.

1. A system comprising:
a time of fight sensor for mounting in or on a first portion of a window unit or a door unit; and a microcontroller unit in communication with the time of flight sensor, wherein the time of flight sensor measures a time for a signal to travel from the time of flight sensor to a reflective surface included in or on a second portion of the window unit or the door unit and back to the time of flight sensor, wherein the time of flight sensor transmits the measured time to the microcontroller unit, and wherein the microcontroller unit uses the measured time to make a security determination.
