Electronic apparatus and controlling method

This invention describes an electronic device that uses a separate, low-power controller and an infrared sensor to detect if someone is nearby. When a person is detected, this controller can turn on the main computer system. A key feature is that the controller can adjust how far the infrared sensor looks, changing its range based on what the main computer system is currently doing.

Why it matters: Since 2019, advancements in low-power embedded controllers and compact infrared sensors have made dynamic, context-aware power management more efficient and cost-effective for portable devices.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModerateInfrared sensor, embedded controller, software logic
