The application provides a mouse with a balanced structure, comprising a shell; a pressing cover connected with the shell, the pressing cover and the shell enclosing a containing chamber; a main control assembly installed in the containing chamber; a balance key assembly installed in the containing chamber and connected with the pressing cover, the balance key assembly being electrically connected with the main control assembly, and the balance key assembly being used to send an instruction to the main control assembly when the pressing cover is pressed. The application installs the main control assembly and the balance key assembly in the shell, and electrically connects the balance key assembly with the main control assembly. When external force acts on the pressing cover, the pressing cover is pressed to press the balance key assembly, so that the balance key assembly is conducted with the main control assembly, and the balance key assembly sends an instruction to the main control assembly. Therefore, compared with the traditional point trigger mouse structure mode, the application can effectively avoid the idle stroke and short stroke of the pressing cover through the balance key assembly, and help to improve the pressing sensitivity of the mouse.

Various techniques for coordinating multiple access point (CMAP) trigger frame (TF) extension schemes in wireless communications are described herein. An apparatus (e.g., an access point (AP)) transmits or receives a trigger frame (TF) that triggers a coordinated beamforming (CBF) transmission. The apparatus then participates in CBF transmission. The TF provides a time extension that enables one or more shared access points to complete recalculation of one or more steering matrices for CBF transmissions prior to participating in the CBF transmissions.

This invention discloses an information interaction system and method based on authorized anchor points. The system includes authorized anchor points, a detection module, a permission verification module, an information acquisition module, and a management platform. Authorized anchor points can be system-preset anchor points or user-defined anchor points, and can be physical anchor points (such as QR codes) or virtual anchor points (such as geofences), storing location identification information and authorization credentials. The detection module monitors whether the user terminal enters the anchor point trigger range (including start-point and end-point triggers) through visual scanning, gesture recognition, near-field sensing, and geographic location detection. When the user initiates an action (such as tapping or scanning a code), the permission verification module obtains credentials and verifies permissions. After successful verification, the information acquisition module enables the user terminal to obtain service data from a preset information source based on the credentials and generate a service response. The management platform is used for centralized configuration, monitoring, and analysis of each anchor point. Users can create their own anchor points and configure start-point / end-point services; multiple anchor points can form a link and trigger sequentially. This invention is applicable to shopping malls, bus stops, express delivery points, hospitals, transportation hubs, and personal scenarios, enabling convenient, secure, continuous, and manageable information interaction.

The invention relates to the technical field of blasting control, in particular to an underwater blasting multi-point synchronous detonation method based on delay control. In order to solve the problems of low multi-point triggering precision and poor triggering reliability caused by uncertain acoustic signal propagation delay, node clock drift and master control communication interruption in an underwater environment, the invention proposes that initial time reference calibration is carried out by establishing a safety communication link between a master control unit and a sub-control node; predicting propagation time delay based on hydrological observation data and a Medwin sound velocity model; generating a feedforward prediction compensation parameter by using Kalman filtering in combination with the historical clock skew sequence; the validity of the trigger instruction is autonomously judged in a distributed manner through majority voting or time window cross validation; and each sub-control node executes detonation operation in parallel according to the local high-precision clock and the compensation parameter, and records an execution log for synchronous precision evaluation.

The invention discloses a multi-point trigger control system and method for elevator shaft lighting by multiplexing a five-party talkback power line. Relates to the field of elevator shaft lighting. A master station control device and a plurality of slave station control devices are all connected to an existing five-party talkback power circuit of an elevator, and an MCU master control module and a carrier communication module are arranged in each device. The MCU master control modules of the slave station control devices detect that local lighting request switches are closed; an illumination request digital instruction containing a master station address is actively generated, modulated by a carrier communication module and then coupled to the power supply circuit; the master station control device receives and demodulates a carrier signal from the line through a carrier communication module, and an MCU master control module analyzes a target address, drives a lighting output control unit to be switched on during matching, and supports direct triggering of a local switch at the same time; therefore, on the premise that no control cable needs to be newly added, intelligent lighting control based on multi-point requests of an existing power line and unified response of a master station is achieved.
