Abstract: The present disclosure relates to code scanning methods based on vehicle-mounted cameras. One example method includes collecting a first image by using a vehicle-mounted camera, parsing a target encoding pattern included in the first image, and when no parsing information is obtained, collecting, based on image data obtained by the vehicle-mounted camera, another image that is close to the first image in a time relationship for parsing to attempt to obtain parsing information in the target encoding pattern.

Abstract: A device model for simulating a leakage current of a semiconductor device is disclosed, including a gate structure having a first metal gate and a metal work function layer of the first conductive type. The leakage current of the device model is acquired by multiplying a main function by a first function. The first function is a function of the metal gate boundary proximity effect parameters of the semiconductor device. These parameters influence the metal gate boundary proximity effect on the leakage current in modeling. Also disclosed is a method to extract the device model of leakage current. The device model simulates the influence of the MBE effects via parameter fitting, thereby improving on the device leakage current and the design of more reasonable layouts.

Abstract: A CB device receives a first packet sent from another device through a stacking port. In response to determining, based on source port information carried in the first packet, that the first packet entered the stacking system from a PE device and the first packet is a non-unicast packet, the switch module performs mirroring processing to the first packet to obtain a mirrored packet, and transmits the first packet and the mirrored packet to a packet buffering module of the CB device. In response to determining that a second packet from the packet buffering module entered the stacking system from the PE device and the second packet is the non-unicast packet, the second packet is forbidden from being forwarded through a first-level stacking port of the CB device.
