Abstract: Techniques are described for supporting user equipment (UE) positioning in a non-terrestrial network (NTN). To allow calculating a position/location of a UE based on reference signal (RS) measurements to and from one satellite (or a terrestrial base station), a device may be configured to calculate a doppler measurement and a range measurement and report such measurements to be used by a location server to calculate a UE position. An example device may receive a first RS (with the first RS being one of a positioning reference signal (PRS) or a sounding reference signal (SRS)), receive a second RS associated with the first RS, calculate a doppler measurement based on one or both of the first RS or the second RS, and report the doppler measurement. The doppler measurement (such as a measured frequency offset) may be used by a location server to calculate a UE position on the earth surface.

Abstract: The device of the present invention converts the kinetic energy of compressed air into electrical energy by setting up (N+1)-level wind turbines with same diameter but different rated power and rated speed in a pipeline and passing the high-speed airflow through the multi-levels of the wind turbine to reduce the airflow speed. The device converts wind energy into electrical energy and mixes atomized water when the compressed air flows through the wind turbines to improve the power generation efficiency. The device is a pipeline power generation device and a dedicated compressed air turbine. The pipeline power generation device can be used by multiple devices in parallel connecting with each other to increase the total power of peak-shaving power. As the result, the cost of the peak shaving power is reduced.

The first hyperzoom is removed from the camera. Tracks of the persons or vehicles are generated based on the updated positions. The second hyperzoom is removed from the camera. Track metadata is generated from the tracks for storing in a key-value database located on a non-transitory computer-readable storage medium of the camera.

Abstract: The present application discloses a pixel driving circuit and a display panel. Before the charging module charges the pixel electrode, the present application releases the voltage of the pixel electrode by means of the discharging electrode. Therefore, it is possible to avoid that the voltage of the pixel electrode is charged to a target value after the residual voltage on the pixel electrode needs to be canceled during charging the pixel electrode by the charging module. As a result, the power consumption of the pixel electrode during the charging/discharging process can be reduced, and the charging/discharging time period of the pixel electrode can be reduced.
