Electronic device and method for detecting presence and motion

An electronic device comprising:

• a housing comprising:
• a top surface having a first corner diagonally opposite a second corner, and a third corner diagonally opposite a forth corner;
• a first opening formed on the first corner of the top surface;
• and
• a second opening formed on the second corner of the top surface;
• a first infrared (“IR”) sensor proximate to the first corner and having an unobstructed path and line of sight to outside the housing via the first opening;
• and
• a second IR sensor proximate to the second corner and having an unobstructed path and line of sight to outside of the housing via the second opening.

A method comprising:

• generating, by a first infrared sensor of an electronic device, a first signal in response to detecting first heat from outside of a first plurality of openings formed in a first corner of a housing of the electronic device;
• generating, by a second infrared sensor of the electronic device, a second signal in response to detecting second heat from outside of a second plurality of openings formed in a second corner of the housing of the electronic device that is diagonally opposite the first corner;
• and
• detecting, by the electronic device, based on the first signal and the second signal, presence of a user of the electronic device, wherein:
• the first infrared sensor is proximate to the first corner with a first unobstructed path and line of sight to outside of the housing via the first plurality of openings;
• the first plurality of openings is oriented toward the first infrared sensor in different directions;
• the second infrared sensor is proximate to the second corner with a second unobstructed path and line of sight to outside of the housing via the second plurality of openings;
• the second plurality of openings is oriented toward the second infrared sensor in different directions;
• the housing includes a third corner diagonally opposite a fourth corner.

A method comprising:

• generating, by a first infrared sensor of an electronic device, a first signal in response to detecting first heat from outside of a first plurality of openings formed in a first corner of a housing of the electronic device;
• generating, by a second infrared sensor of the electronic device, a second signal in response to detecting second heat from outside of a second plurality of openings formed in a second corner of the housing of the electronic device that is diagonally opposite the first corner of the housing, wherein the housing includes a third corner diagonally opposite a fourth corner;
• and
• detecting, by the electronic device, based on the first signal and the second signal, presence of a user of the electronic device;
• and
• detecting, based on a relative change of the first signal and the second signal, motion of a user of the electronic device, wherein:
• the first infrared sensor is proximate to the first corner with a first unobstructed path and line of sight to outside of the housing via the first plurality of openings;
• the first plurality of openings are oriented toward the first infrared sensor in different directions;
• the second infrared sensor is proximate to the second corner with a second unobstructed path and line of sight to outside of the housing via the second plurality of openings;
• the second plurality of openings are oriented toward the second infrared sensor in different directions.
