The connecting portion further includes a mounting hole, and the connecting portion further includes a first surface and a second surface opposite to the first surface. The anti-theft body includes an anti-theft portion disposed on an inner surface thereof and mounted onto the mounting hole so that the anti-theft portion detachably connected to the first surface of the connecting portion to cover the at least one fixing hole.

Abstract: A vehicle roof rack is provided and includes: a first cross rod and a second cross rod. The first cross rod includes a first connection end and a first mounting end. The second cross rod includes a second connection end and a second mounting end. The first connection end includes a plurality of first connection portions, the second connection end is selectively connected to any one of the plurality of first connection portions to adjust a distance between the first connection end and the second connection end.

Abstract: This disclosure describes systems and techniques for synchronizing cameras and tagging images for face authentication. For face authentication by a facial recognition model, a dual infrared camera may generate an image stream by alternating between capturing a “flood image” and a “dot image” and tagging each image with metadata that indicates whether the image is a flood or a dot image. Accurately tagging images can be difficult due to dropped frames and errors in metadata tags. The disclosed systems and techniques provide for the improved synchronization of cameras and tagging of images to promote accurate facial recognition.

Abstract: This document describes techniques and systems that enable automatic exposure and gain control for face authentication. The techniques and systems include a user device initializing a gain for a near-infrared camera system using a default gain. The user device ascertains patch-mean statistics of one or more regions-of-interest of a most-recently captured image that was captured by the near-infrared camera system. The user device computes an update in the initialized gain to provide an updated gain that is usable to scale the one or more regions-of-interest toward a target mean-luminance value. The user device dampens the updated gain by using hysteresis. Then, the user device sets the initialized gain for the near-infrared camera system to the dampened updated gain.

Abstract: A switching method for an electronic device includes: acquiring first environment information at first time; acquiring second environment information at second time, the second time being later than the first time; determining whether the first environment information satisfies a first condition; and in response to the first environment information satisfying the first condition, switching the electronic device from a first operation mode to a second operation mode. In the first operation mode, the electronic device processes second environment information in a first processing manner; and in the second operation mode, the electronic device processes the second environment information in a second processing manner.

Abstract: A menu generating method for a TV set is provided in the present disclosure. The menu generating method includes the following steps of: step a: reading menu item data by a system; and step b: determining a classification to which the menu item belongs, wherein if the menu item belongs to a first classification, then the menu item is longitudinally filled into a menu frame, and if the menu item belongs to a second classification, then the menu item is laterally filled into the menu frame according to a menu of the first classification to which the menu belongs. With the menu generating method for a TV set according to the present disclosure, menus can be displayed automatically according to properties of the menus. This allows the menus to be displayed in a very simple and clear way, which makes it convenient for the user to operate the menus.
