Abstract: This application provides a method and an apparatus for determining a pull-out direction. The method includes: obtaining environmental information of a current parking space and a parking record of a vehicle; and determining, based on the environmental information and the parking record, a first direction towards which the vehicle pulls out of the current parking space. According to the method for determining a pull-out direction in this application, an appropriate pull-out solution is recommended to a user based on the environmental information of the current parking space and the parking record of the vehicle. This improves user experience and ensures driving safety.

Abstract: A locking apparatus is provided that relates to a fastener and is used to solve a problem that time and labor are consumed and installation efficiency is low in a locking process of an existing locking apparatus. The locking apparatus is configured to lock a first module and a second module, and includes a locking body that is installed on the first module and a locking piece that is installed on the second module. The locking body includes a housing and a rotating block disposed inside the housing, where the rotating block is connected to a handle that drives the rotating block to rotate out of or into the housing, and the locking piece has a notch that accommodates the rotating block. The present invention is used to implement locking between modules.

Abstract: A method for treating a substrate is disclosed in which a propellant stream is passed through a channel and directed toward a substrate. Substrate pre-marking or post-marking treatment material is controllably introduced into the propellant stream and imparted with sufficient kinetic energy thereby to be made incident upon a substrate. A multiplicity of channels for directing the propellant and treatment material allow for high throughput, high resolution in-situ treatment. Marking materials and treatment materials may be introduced into the channel and mixed therein prior to being made incident on the substrate, or mixed or superimposed on the substrate without registration. One example is a single-pass, full-color printer.
