Patent Images
1. An electronic device comprising:
- a housing including an outer surface having an opening formed thereon;
an infrared (“
IR”
) sensor disposed in the housing and adjacent to the opening, the IR sensor being configured to;
receive heat emitted by a person from outside of the housing via the opening; and
generate a signal in response thereto;
wherein the IR sensor has an unobstructed path and line of sight through the opening to outside of the housing.

Abstract
An electronic device for detecting presence includes a housing and an infrared (“IR”) sensor. The housing includes an outer surface having an opening formed thereon. The IR sensor is disposed in the housing and adjacent to the opening. The IR sensor has an unobstructed path and line of sight through the opening to outside of the housing. The IR sensor is configured to receive heat emitted by a person from outside of the housing via the opening and to generate a signal in response thereto.

11. An electronic device comprising:
-
a housing including an outer surface having an opening formed thereon; an first infrared (“
IR”
) sensor disposed in the housing and adjacent to the opening; anda second IR sensor disposed in the housing and adjacent to the opening, the second IR sensor has a smaller target area than the first IR sensor; wherein the first IR sensor has an unobstructed path and line of sight through the opening to outside of the housing; wherein the second IR sensor has an unobstructed path and line of sight through the opening to outside of the housing; wherein the first IR sensor is configured to; receive heat emitted by a person from outside of the housing via the opening; and generate a first signal in response thereto; and wherein the second IR sensor is configured to; receive heat emitted by the person from outside of the housing via the opening; and generate a second signal in response thereto. - View Dependent Claims (12, 13, 14)
