1. A method, comprising:
- receiving sensor data representative of temperature information captured in a field of view of an infrared (IR) sensor;
detecting if a temperature differential in the received sensor data exceeds a threshold value;
quantifying a similarity between the sensor data received during the detected temperature differential and one or more stored profiles; and
determining a presence or an absence of a user in the field of view of the IR sensor based on the similarity between the data received during the detected temperature differential and at least one of the stored profiles.

Abstract
A system configured to collect sensor data and compare the sensor data to a first template profile comprising data indicative of an approach of a user or compare the sensor data to a second template profile comprising data indicative of a departure of a user, or a combination thereof to determine whether the sensor data indicates the approach of a user or a departure of a user.

8. A device to detect a user approach or departure or a combination thereof, comprising:
-
a sensor to collect sensor data; and a processor to compare the sensor data to a first template profile comprising data indicative of an approach of a user or compare the sensor data to a second template profile comprising data indicative of a departure of a user, or a combination thereof to determine whether the sensor data indicates the approach of a user or a departure of a user. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)

18. A method to detect a user motion proximate a device, comprising:
-
receiving, by a processor, sensor data corresponding to an area proximate the device; determining, by the processor, whether a differential value of a first point and a second point in the sensor data exceeds a threshold differential; if the differential value exceeds the threshold differential then determining, by the processor, whether the first point is outside of a norm for the sensor data; if the first point is determined to be outside of the norm then triggering, by the processor, execution of a user motion analysis; and determining, by the processor, a user intent to engage or disengage the device based on the user motion analysis. - View Dependent Claims (19, 20, 21, 22)
