Abstract: A water sport apparatus is disclosed. The water sport apparatus comprises: a propulsion system that is configured to propel the water sport apparatus, the propulsion system comprising: an impeller; and a drive system that is configured to drive the impeller to propel the water sport apparatus. The water sport apparatus comprises a controller for controlling the propulsion system, the controller comprising a sensor system; wherein the controller is configured to: determine a speed estimate that is indicative of a speed of the water sport apparatus using sensor data determined using the sensor system; compare the speed estimate to a speed threshold; and activate the drive system to drive the impeller in response to the speed estimate being equal to or greater than the speed threshold.

Abstract: 一种测量流体表面流速的方法、装置及存储介质。流速测量方法首先采集待处理视频，基于视频采用预设规则确定视频中流体表面的监测区域，监测区域能够较好地代表流体表面的流速；根据监测区域在流体表面的位置，调整雷达系统的位姿，使得调整后的雷达系统朝向监测区域，并向监测区域内发射雷达信号；获取雷达信号的点云数据，并根据点云数据获取监测区域流体表面的流速，并作为流体表面的第一流速。该流速测量方法基于视觉信息进行雷达自适应位姿调整，避开非适宜的观测区域，从而基于雷达信号对应的点云数据确定流体表面的第一流速，保证了流速测量结果的准确性。

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, are described for implementing a mission space platform. The platform is configured to identify radio frequency (RF) signals and analytics and generate a graphical interface with a map of a geographic area, where the map includes multiple grid points. For one or more RF signals: the platform determines a respective geolocation of an emitter that emits the RF signal and assigns the RF signal and its corresponding emitter to a grid point of the map based on the respective geolocation. Visual characteristics of grid points in the map are dynamically adjusted, in real time, based on new RF information about the area. The new RF information is provided as an output at the interface by displaying adjustments to the visual characteristics of the grid points.

Abstract: Machine learning techniques to mitigate multipath in a GNSS receiver that includes a first trained model that provides extra path length (EPL) corrections in the GNSS receiver. The first trained model can be updated using an updated and trained model from one or more assistance servers that are in communication with the GNSS receiver. The GNSS receiver can provide, for a particular computed positio and time, extracted features from received GNSS signals to the one or more assistance servers. The assistance servers can then use th extracted features and a source of true EPL corrections to train a server model. The server model can be transmitted to the GNSS receiver to replace the first trained model. The server model and the source of true EPL corrections can be specific for a geographic region, so different regions have different server models based on the corresponding sources of true EPL corrections..
