Abstract: This application provide a retransmission control method, a communications interface, and an electronic device. When a transmit end transmits a first data packet to a receive end and does not receive an acknowledgement corresponding to the first data packet within a first RTO, the transmit end retransmits a second data packet based on a second RTO. The second data packet is a data packet transmitted by the transmit end after the transmit end transmits the first data packet. The second RTO is related to a receive timestamp of the acknowledgement corresponding to the first data packet and a transmit timestamp of the first data packet.

Abstract: A method for determining a presence of an occupant within a vehicle includes capturing, via a driver facing camera, video image data, including a plurality of image frames of a field-of-view of the driver facing camera. At least one area-of-interest within the image frames is defined, and a foreground pixel count of each image frame of each area-of-interest is determined. At each Nth image frame, an occupancy for each area of interest is determined based at least in part on the foreground pixel count.

A history of the occupancy determination for each area-of-interest is maintained, and a final status for each area-of-interest is determined based on the respective history of occupancy. External indicators are initiated based on the final status determination.
