Abstract: A zoom method and an apparatus to improve zoom accuracy of a camera module are disclosed. The zoom method includes: controlling, based on a target focal length, the lens to move in different subregions when the lens moves in an operation region, and determining position information of the lens based on a position detection relationship of a subregion in which the lens is currently located. The lens is controlled to move based on a position of the lens detected when the lens moves, so that the lens can more accurately stop at a position corresponding to the target focal length. This helps improve focusing accuracy of the camera module.

Abstract: An SPI-based data transmission system is provided. In the system, a master SPI apparatus enables a first slave SPI apparatus by using a combination of a first and a second chip select signal. In response to the master SPI apparatus driving the first chip select signal to be in an enable state and driving the second chip select signal to be in a disable state, the master SPI apparatus controls a second slave SPI apparatus to send data using a data line. The master SPI apparatus further receives data by using the data line, and the first slave SPI apparatus receives data using the data line. When the first chip select signal is in the enable state and the second chip select signal is in the disable state, the master SPI apparatus and the first slave SPI apparatus can simultaneously receive data transmitted by the second slave SPI apparatus.

Abstract: The present disclosure is directed to inventive systems, methods, and devices for use in an outdoor lighting network for drone detection. The drone detection system includes one or more lighting fixtures, one or more radar sensors to detect a moving object, and one or more controllers. The controllers receive data from the sensors, determine the velocity and velocity change rate of the object over a period of time, and analyze flight data pertaining to the moving object to determine if the object is a drone. The system can determine the starting location of the moving object, and send a signal indicating its starting location. The system can also track the position of the moving object in the outside environment.

Abstract: Disclosed is a privacy-preserving neural network prediction system in the technical field of information security. The system includes a client, a server and a third party device. Off-line, the client, the server and the third party complete model parameter sharing through negotiation. Online, the client sends/shares input data to the server. The client and the server use a secure calculating protocol to jointly execute neural network prediction with privacy preservation. The server returns an obtained prediction result to the client, and the client reconstructs the prediction result. Only one round of communication interaction is required, and the amount of communication overhead is reduced, so that the communication efficiency significantly improves. The calculations in the present system may be based on a ring, rather than a domain. The present system also (re)customizes the offline protocol, which improves the offline efficiency and requires only a lightweight secret sharing operation.
