Title: SENSOR SYSTEMS AND METHODS FOR AN AIRCRAFT LAVATORY
Abstract: A method (400) may comprise receiving (402), 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 (402), 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.

Claims: number: 1
text: A method (400) of determining whether an object is in an intended zone of influence, the method comprising,
number: 2
text: The method of claim 1, further comprising commanding, via the processor, an electrically activated device associated with the first sensor in response to determining the object is within the first intended zone of interest.
number: 3
text: The method of claim 1 or 2 wherein the first null hypothesis corresponds to a first probability model and the second null hypothesis corresponds to a second probability model.
number: 4
text: The method of claim 3, wherein the first probability model and the second probability model are given by P(H0|y 0
number: 5
text: The method of claim 4, wherein the first alternative hypothesis corresponds to a third probability model and the second alternative hypothesis corresponds to a fourth probability model.
number: 6
text: The method of claim 5, wherein the first alternative hypothesis and the second alternative hypothesis are given by f(x0|y0
number: 7
text: The method of any preceding claim, wherein the first sensor and the second sensor are presence sensors, or wherein the first sensor and the second sensor are infrared sensors.
number: 8
text: A false detection system for a multi-sensor system, comprising:
number: 9
text: The false detection system of claim 8, wherein the main controller is further configured to determine whether the first sensor or the second sensor is within an intended zone of interest of the respective sensor, and optionally wherein the main controller is further configured to send, via the processor and through a local controller, a signal to an electrically activated device corresponding to the first sensor in response to determining the first sensor is within the intended zone of interest.
number: 10
text: The false detection system of claim 8 or 9, wherein the main controller is further configured to determine whether the first sensor or the second sensor is falsely detecting the object within the respective zone of interest further comprises determining a null hypothesis that the object is within a respective intended zone of interest and determining an alternative hypothesis that the object is outside the respective intended zone of interest.
number: 11
text: The false detection system of any of claims 8 to 10, wherein the first sensor and the second sensor are configured for detection of non-linear and non-Gaussian motion, or wherein the first sensor and the second sensor are presence sensors.
number: 12
text: An aircraft lavatory, comprising:
number: 13
text: The aircraft lavatory of claim 12, wherein the main controller is further configured to command, through the first local controller, the first electrically activated device to operate in response to determining the object is intended for to operate the first electrically activated device.
number: 14
text: The aircraft lavatory of claim 12 or 13, wherein the first electrically activated device is a valve of a faucet system, or wherein the first electrically activated device is an actuator of a toilet seat system, or wherein the first electrically activated device is a pump of a soap dispensing system.
number: 15
text: The aircraft lavatory of claim 12, 13 or 14, further comprising a faucet system including the first sensor, the first electrically activated device, and the first local controller.
