  • Publication number: 20240100697
    Abstract: The present disclosure relates to a multi-thread controller for a parallel robot. All tasks are concentrated in four layered threads, namely, a main thread, a real-time thread, a preprocessing thread and a background thread; different priorities of tasks are placed in different levels of threads, so that motion logic is first ensured, second motion planning, then communication and interface interaction, and finally file reading and time consumption calculation; various operations are strictly performed in respective threads; and between the threads are provided a thread security queue for data interaction and a thread clock calling and task pushing mechanism, so that the security of communication calling and the flexibility of data interaction are realized between the threads.

  • Patent number: 11938678
    Abstract: Disclosed herein are an adhesion blocking element, a three-dimensional printing device and a three-dimensional printing method. The adhesion blocking element comprises: one light-transmittable main body comprising a first surface and a second surface which are disposed opposite to each other, and side faces connecting the first surface and the second surface; and a plurality of microstructures arranged on the main body, wherein each microstructure has one cavity formed in the main body and one first open face which is arranged on the first surface of the main body and communicated to the cavity. The present invention decreases the adhesion between the adhesion blocking element and the cured layer by improving the structure of the adhesion blocking element itself, and eliminates the negative pressure adsorption between the cured layer and the adhesion blocking element, so that it is easier to peel the adhesion blocking element off from the cured layer.

  • Patent number: 11941979
    Abstract: The present application discloses a traffic light control method for an urban road network based on expected return estimation, which uses C-V2X wireless communication technology to obtain real-time information of all vehicles and traffic state in the road network from vehicle-mounted terminals, and adaptively and dynamically controls the phase transformation of the traffic light. According to the present application, the expected returns of keeping the current phase and executing phase switch are calculated by estimating the timely driving distance and the future driving distance of the passable vehicles in the next green light duration in combination with the proposed road priority traffic index. By comparing the expected returns of keeping the current phase or switching to other phases, the best phase is selected, so as to make as many passable vehicles travel farther as possible in the next green light duration. Therefore, the efficiency of traffic will be improved.

  • Patent number: 11938581
    Abstract: A power device includes a power tool, a mounting plate, a mounting table, a positioning assembly, and a locking assembly. The positioning assembly includes a positioning piece. A positioning space is formed between the positioning piece and the mounting table. An end of the mounting plate is enabled to be inserted into the positioning space so that the mounting plate is pre-positioned. The locking assembly includes a movable piece and a locking piece. The movable piece includes a support position where the mounting plate is supported and an unlocked position where support for the mounting plate is released. The locking piece fixes at least the mounting plate to the mounting table.

  • Publication number: 20240071099
    Abstract: The present application discloses a method and a device for estimating the position of a networked vehicle based on independent non-uniform increment sampling. By mapping a laser radar point cloud to a spatiotemporal aligned image, independent non-uniform increment sampling is carried out on the mapping points falling in an advanced semantic constraint region of the image according to a point density of the depth interval where the mapping points are located, and the virtual mapping points generated by sampling are reversely mapped to the original point cloud space and merged with the original point cloud, and the combined point cloud is used to estimate the position of the networked vehicle based on a deep learning method, so as to solve the inaccurate position estimation problem of sheltered or remote networked vehicles due to the sparseness or missing of its own point cloud clusters.

  • Patent number: 9846460
    Abstract: The present invention provides a server system and a limiting mechanism used thereby. Through mutual cooperation between the limiting mechanism which sets on a server rack and sliding grooves and limiting holes which are formed in outer side walls of a server case, when internal components of the server case are drawn out, a rear end of the server case can be effectively prevented from turning up or falling down, the problem of case fixation when the server rack uses a tray type sliding rail is solved, the structure is simple and reliable and the practicability is very high.

  • Patent number: 9430069
    Abstract: A touch scanning method includes, in the absence of a touch, performing a coarse scanning on the touch screen, and in the presence of a touch, performing a fine scanning on a full detection-activated region containing a touch point while performing the coarse scanning on the remaining region other than the full detection-activated region. During coarse scanning, in first M frames of M+N successive frames, drive lines spaced apart from one another by at least one of the drive lines are driven, and sense lines spaced apart from one another by at least one of the sense lines are detected. In the succeeding N frames of the M+N frames, there is no activity in the drive and sense lines. During the fine scanning, each drive line and each sense line within the full detection-activated region is driven and detected, respectively.
