Triangulation with co-located sensors
First Claim
1. A method of detecting an event in a structure using sensors and at least one actuator, the method comprising:
- sending a signal from the at least one actuator encapsulated in a device;
returning a reflected wave signal from the event to each of the sensors in the device;
determining a respective duration of time for which the signal travels from the event to each of the sensors; and
calculating a location of the event by using differences in the respective durations of time for which the signal travels from the event to each of the sensors to determine an angle and a distance at which the event is positioned.

Abstract
A method of detecting an event in a structure using a device having sensors and at least one actuator includes sending a signal from the at least one actuator encapsulated in the device, returning a reflected wave signal from the event to each of the sensors in the device, determining a respective duration of time for which the signal travels from the event to each of the sensors, and calculating a location of the event by using differences in the respective durations of time for which the signal travels from the event to each of the sensors to determine an angle and a distance at which the event is positioned.

5. A device for use in detecting one of an event or a feature in a structure, the device comprising:
-
at least three sensors positioned substantially co-planar in a device; and
an actuator positioned in the device;
wherein the device is configured to determine the location of one of an event or a feature by generating a signal and recording a time of flight of the signal with respect to each of the at least three sensors. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)
