Abstract: The present invention discloses a watermark embedding method based on service invocation data, comprising obtaining service invocation data, and preprocessing the invocation data, then, obtaining the key data through screening the preprocessed invocation data based on relevant weights, then, adding timestamps to the key data to obtain enhanced data, after that, selecting the contribution degree of the enhanced data to obtain high-quality data, and encoding the high-quality data to generate encoded data, then, constructing a data watermark embedding model by employing the encoded data, and inputting the service invocation data to be embedded into the data watermark embedding model, and thus the embedding results can be output. This method can not only improve the accuracy of watermark embedding for service invocation data, but also provides good interpretability, making it directly applicable to watermark embedding systems.

The method includes: determining position information of a target object in a framing picture of a camera, the position information including coordinate information and dimension information of the target object in the framing picture; determining a target heading angle of the UAV and a target pitch angle of a gimbal based on the position information; adjusting the UAV from an initial heading angle to the target heading angle and adjusting the gimbal from an initial pitch angle to the target pitch angle; determining a target shooting position based on a shooting mode of the camera and the position information; and flying to the target shooting position and controlling the camera to shoot the target object at the target shooting position.

Abstract: An electronic file is accessed. The electronic file contains a first type of data that meets one or more specified sensitivity criteria. Via an embedding module, the first type of data is embedded into an electronic database. After the first type of data is embedded, a plurality of requests to query the first type of data is received. Based on the received requests, a noise module adds a different type or amount of noise to the embedded first type of data for each request. The first type of data is outputted after the noise has been added to the first type of data. A machine learning process is performed at least in part based on the outputted first type of data after the noise has been added. An overall characteristic of the first type of data is determined based on a result of the machine learning process.

Abstract: Systems and methods for softly restarting a power network using an inverter-controlled energy storage system are provided. In response to an event such as a fault or other condition, a power network bus that provides power to one or more industrial loads (e.g. motors) can be disconnected from the utility grid. Instead of automatically recoupling the power network bus to the grid after a specified time period, a soft restart is accomplished by pre-energizing the power network bus with an energy storage system (ESS) according to a ramp up process and synchronizing the power network bus with the utility grid while the power network bus operates in an islanded mode. The power network bus can then be reconnected to the utility grid, for instance, by reclosing the one or more circuit breakers coupled between the power network bus and the utility grid.
