System and method for detecting human presence using a charge domain imaging device and range sensor for an information handling system

A method to detect human presence near an information handling system a range sensor and a charge domain imaging device operating in tandem comprising:

• detecting, with the range sensor formed on a base chassis of the information handling system, a moving presence is within a first detection range from the information handling system and provide that first detection range data to a charge domain imaging device formed into a top portion of a lid of the information handling system for access to software modules of the information handling available to a user within the first detection range;
• detecting, with the range sensor, the moving presence within a second detection range closer than the first detection range from the information handling system and provide that second detection range data to the charge domain imaging device to trigger a low-resolution imager at the charge domain imaging device to capture low resolution images of the user within the second detection range, where the second detection range corresponds to an operational range of the low-resolution imager from the information handling system;
• and
• processing, with a charge domain imaging device microprocessor, sensor data of the captured low resolution images from an array of image sensors with execution of machine readable code instructions of a charge domain artificial intelligence module onboard the charge domain imaging device to engage in facial recognition from the captured low resolution image.

An information handling system operating in a sleep state having plural sensors to detect human presence near the information handling system comprising:

• a hardware processor, a data storage device, and a power management unit (PMU) to provide power to the hardware processor and data storage device;
• a range sensor to detect a moving presence within a first detection range from the information handling system and provide that first detection range data to a charge domain imaging device for access to software modules of the information handling available to a user within the first detection range;
• the range sensor to detect the moving presence within a second detection range closer than the first detection range from the information handling system and provide that second detection range data to the charge domain imaging device to trigger a complimentary metal-oxide semiconductor (CMOS) imager at the charge domain imaging device to capture low resolution images of the user within the second detection range;
• a charge domain imaging device microprocessor to process sensor data of the captured low resolution images from an array of image sensors of the CMOS imager with execution of machine readable code instructions of a charge domain artificial intelligence module onboard the charge domain imaging device to engage in facial recognition from the captured low resolution image to identify presence of the user in front of the information handling system.
