Abstract:
A toner cartridge is disclosed. A hole and a window are disposed on two sides of a cartridge body separately. A toner hopper is disposed in the cartridge body, and is configured to accommodate toner, and a supply opening exposed in the window is disposed at a position that is on the toner hopper and that faces the window. The first agitator is disposed in the toner hopper, and is configured to transport the toner in the toner hopper to the supply opening. A first hopper door is slidably disposed on a side that is of the toner hopper and that faces the window, a slot is disposed on the first hopper door, and the first hopper door may open or close the supply opening when sliding. The first clamping hook is disposed on the second side of the cartridge body.
Abstract:
A radar system and a terminal device are provided. The radar system includes a controller and at least two radar modules directly or indirectly connected to the controller. The at least two radar modules include a first radar module and a second radar module, and the first radar module and the second radar module implement time division multiplexing of the controller in a digital domain. Compared with an existing radar system, the radar system in this application can provide more transmit channels, more receive channels, and a larger antenna array size when the two radar systems include a same quantity of controllers.
Abstract:
The disclosure relates to technology for object detection in which a vision system receives training datasets including a set of two-dimensional (2D) images of the object from multiple views. A set of 3D models is reconstructed from the set of 2D images based on salient points of the object selected during reconstruction to generate one or more salient 3D models of the object that is an aggregation of the salient points of the object in the set of 3D models. A set of training 2D-3D correspondence data are generated between the set of 2D images in a first training dataset of the training datasets and the salient 3D model of the object generated using the first training dataset. A deep neural network is trained using the set of training 2D-3D correspondence data generated using the first training dataset for object detection and segmentation.
Abstract:
A data transmission method, implemented by a network device, includes sending a probe packet to a log server, determining whether the log server can receive a packet responsive to whether the network device receives a probe response packet from the log server, and sending a log packet to the log server when the log server can receive a packet. The log packet includes a correspondence between a public Internet Protocol (IP) address and a private IP address.
Abstract:
Embodiments of the present invention provide a remote electrical tilt unit, a base station, and a method for managing a remote electrical tilt antenna. The method includes: receiving, by the remote electrical tilt unit, permission configuration information sent by a first base station through a group of AISG ports of the remote control unit; configuring management permission of the first base station on the remote electrical tilt unit according to the permission configuration information, where the management permission includes at least control permission and query permission, and control permission on the remote electrical tilt unit can be allocated to only one base station. In this way, multiple base stations jointly manage a remote electrical tilt unit in a remote electrical tilt antenna, and a problem that it is difficult to locate and troubleshoot a fault when configuration of the remote electrical tilt unit is incorrect is resolved.

Abstract:
The present invention provides a method and an apparatus for transmitting a broadcast signal. The method includes: performing dividing processing on an antenna array in a multi-antenna system to obtain multiple subarrays; obtaining a basic weight vector of each subarray among the multiple subarrays, where the basic weight vector makes a beam peak-to-average power ratio of each subarray lower than a preset threshold and makes beam patterns of different subarrays complementary to each other in a direction dimension; performing, according to a weight coefficient in each basic weight vector, weighted processing on a transmit signal of an array element in a subarray corresponding to the each basic weight vector to obtain a first signal and use the array element to transmit the first signal. The present invention implements full coverage of the broadcast signal from the multi-antenna system in all directions in a cell or a sector.
