Abstract
A method may comprise receiving, via a processor, a first indication that an object is in a first zone of interest of a first sensor in the plurality of sensors; receiving, via the processor, a second indication that the object is in a second zone of interest of a second sensor in the plurality of sensors; and determining, via the processor, whether the first sensor or the second sensor is falsely detecting the object within the respective zone of interest.
Claims19
A method of determining whether an object is in an intended zone of influence, the method comprising,
- receiving, via a processor and through a first sensor, a first indication that the object is within a first zone of interest;
- receiving, via the processor and through a second sensor, a second indication that the object is within a second zone of interest;
- determining a first null hypothesis corresponding to the object being outside a first intended zone of interest of the first sensor;
- determining a second null hypothesis corresponding to the object being outside a second intended zone of interest of the second sensor;
- determining a first alternative hypothesis corresponding to the object being inside the first intended zone of interest;
- determining a second alternative hypothesis corresponding to the object being inside the second intended zone of interest;
- calculating, via the processor, a posterior probability and a posterior density over the first zone of interest and the second zone of interest;
- and
- determining, via the processor, whether the object is within the first intended zone of interest or the second intended zone of interest.
A false detection system for a multi-sensor system, comprising:
- a plurality of sensors, each sensor including a zone of interest;
- a main controller in operable communication with the plurality of sensors the main controller configured to:
- receive, via a processor, a first indication that an object is in a first zone of interest of a first sensor in the plurality of sensors;
- receive, via the processor, a second indication that the object is in a second zone of interest of a second sensor in the plurality of sensors;
- determine, via the processor, a null hypothesis that the object is within a respective intended zone of interest
- determine an alternative hypothesis that the object is outside the respective intended zone of interest;
- and
- determine, via the processor, whether the first sensor or the second sensor is falsely detecting the object within the respective zone of interest based on the null hypothesis and the alternative hypothesis.
An aircraft lavatory, comprising:
- a first sensor;
- a second sensor;
- a first electrically activated device;
- a second electrically activated device;
- a first local controller in operable communication with the first sensor and the first electrically activated device;
- a second local controller in operable communication with the second sensor and the second electrically activated device;
- and
- a main controller in operable communication with the first local controller and the second local controller, the main controller configured to determine whether an object is intended to activate the first electrically activated device or the second electrically activated device in response to the object being disposed in overlapping ranges of the first sensor and the second sensor.
