Brief Introduction
HC search engine further optimizes search results through its world-leading text analysis and collection technology, achieving a perfect combination of AI and search engine technologies. The extraction of search results no longer depends on a certain evaluation standard, but changes keyword-based matching to concept-based search based on the individual requirements of users. The content related to user requirements is extracted a

I. PrefaceThe HC-SR04 ultrasonic ranging module provides 2cm-400cm non-contact distance sensing, ranging accuracy up to 3mm, and the module includes an ultrasonic transmitter, receiver and control circuitry. such as a smart car ranging and steering, or some projects, often used. Intelligent car ranging can be found in the front of the obstacles in time, so that the smart car can be turned in time to avoid obstacles, so, we will learn this sensor today

When the database structure changes, such as adding tablespaces and data files, such as shutdown allowed, close the database normally, and re-create a full backup of the database. Otherwise, back up the control file and back up the data file as usual. Online log files are written on the array without mirroring or backup.
