The present disclosure provides a method and apparatus for transmitting an image, a computer-readable storage medium, and a computer program product, relating to the technical fields of artificial intelligence such as image compression, computer vision, and autonomous driving. A specific implementation of the method includes: determining a collection environment corresponding to a target image based on a collection position of the target image in an electronic map; determining a target bit rate based on the collection environment; compressing the target image based on the target bit rate to obtain a compressed image; and uploading the compressed image to a target device based on a preset communication path. In this way, the collection environment can be evaluated through a collection position of the image, and the bit rate used when the image is uploaded can be dynamically adjusted based on differences in the collection environment. This enables, on the premise of ensuring the use quality of the uploaded image, reducing the amount of transmission resources used during the image upload process and lowering bandwidth requirements during the transmission process.

The locking member (300) has a locking pin (330) provided with a locking protrusion (332) in a radial direction and configured to be movable between a locked position and an unlocked position. When the locking pin (330) is in the locked position, the locking pin (330) is locked to the mating locking member (210) to block relative movement between the first component (100) and the second component (200). When the locking pin (330) is in the unlocked position, the locking pin (330) is unlocked from the mating locking member (210) to allow the relative movement between the first component (100) and the second component (200). The driving member (400) is configured to drive the locking pin (330) to move between the locked position and the unlocked position and to rotate the locking pin (330) about its own axis. The locking mechanism according to the present disclosure is capable of reliably maintaining or releasing relative positioning between the two components (100, 200).

A method for operating a runtime system for an industrial control environment comprises steps of defining a parent process in the runtime system; starting at least a first child process and a second child process from the parent process in the runtime system; establishing a first private bidirectional communication channel between the parent process and the first child process, and a second private bidirectional communication channel between the parent process and the second child process; receiving, at the second child process, a first handshake request from the first child process via a communication channel; and verifying, at the second child process, the authenticity of the first handshake request. Verifying the authenticity of the first handshake request comprises sending a first attestation request to the parent process via the second private bidirectional communication channel, and receiving a first attestation confirmation from the parent process via the second private bidirectional communication channel.

The present disclosure provides a shoulder strap height adjusting mechanism. The shoulder strap height adjusting mechanism includes a seat pad and shoulder straps. The seat pad is provided with shoulder strap perforations through which the shoulder straps pass and shielding sheets located at the shoulder strap perforations. The shielding sheets at least partially shield the shoulder strap perforations and divide the shoulder strap perforations into an upper perforation and a lower perforation with different heights that extend substantially in the transverse direction. A communication hole is formed between the two perforations, communicating the upper perforation and the lower perforation. Extending directions of the upper perforation and the lower perforation are parallel, and the communication hole extends substantially in the height direction. Two shoulder straps are provided, and two shoulder strap perforations are arranged side by side on the seat pad, with two shielding sheets respectively located at the two shoulder strap perforations. The two shoulder strap perforations are at the same height. Two sliding straps are disposed in the two shoulder strap perforations and extend respectively along the height direction. The two shoulder straps pass through the two shoulder strap perforations respectively and are slidably connected to the corresponding sliding straps through fasteners. The present disclosure further provides a seat cloth and a child carrier.
