The application provides a superlens mouse and a terminal device, which comprise a shell, a light source, an imaging sensor, a superlens and a see-through part. The superlens, the light source, the imaging sensor and the see-through part are arranged in a mounting cavity of the shell, the superlens is located between the light source and the imaging sensor and is used for refracting light emitted by the light source to the imaging sensor. The see-through part is located at the bottom of the shell, the bottom surface of the shell is provided with a light transmission hole; the see-through part is used for refracting the light refracted by the superlens to the light transmission hole and refracting the light reflected at the light transmission hole to the imaging sensor. The light emitted by the light source is refracted to the imaging sensor through the superlens, so that the superlens mouse captures a moving path through a light control principle, effectively improves operation response speed and solves the problem of operation delay. Meanwhile, no key and roller structure is arranged on the shell, the shell structure is effectively simplified, the production cost of the superlens mouse is reduced and the production efficiency is improved.

The application discloses a flood releasing device for hydraulic engineering, which comprises a flood releasing base, a water retaining wall and a flood releasing gate, a flood releasing groove is formed in the flood releasing base, the flood releasing gate is arranged on one side of the flood releasing groove, the flood releasing gate comprises a gate, a portal frame, a screw rod, a driving assembly and a hand wheel, a flood releasing hole is formed in the gate, the portal frame is fixedly arranged on the top of the flood releasing base, a sliding groove is formed in the portal frame and the flood releasing base, and the gate is slidably connected with the sliding groove. The flood releasing device for hydraulic engineering integrates a separate opening and closing assembly on the main gate, when only small flow needs to be released, the heavy main gate does not need to be driven, and only by controlling the opening degree of the cover gate, stepless and fine adjustment of the flow can be realized, the operation response is fast, the energy consumption is low, when large flow needs to be released, the cover gate can be closed first, then the main gate is lifted, full opening degree flow releasing is realized, and the flexibility and working condition adaptability of the flood releasing operation are enhanced.

The present disclosure provides a data processing method and device, and the main technical features include: in response to a user's operation instruction, determining the pointing of a push pointer and a pop pointer according to the instruction type of the operation instruction; based on the pointing of the push pointer and the pop pointer, determining the logical attribution of a target transaction record related to the operation instruction; based on the target operation data associated with the target transaction record, executing the operation instruction on the operation object, which reduces the data processing amount in the operation execution process and improves the operation response speed.

The invention provides a method for effectively solving the problem of insufficient available memory of a 32-bit program process space, which comprises the following steps of: analyzing a source code of a main program, and splitting a functional module to obtain a plurality of sub-functional modules; developing a new program matched with the sub-function module, adding a user-defined message processing function into a sub-program of the sub-function module, unifying a scheduling interface of the sub-function module, and completing program packaging of the sub-function module; creating a shared memory area, and fusing the windows of the main program and the subprogram in the shared memory area to obtain a unified interface; performing data interaction and program function scheduling between the windows, and developing a fusion program to complete cross-process communication of window messages; wherein a socket technology is introduced to carry out network communication between programs. According to the method, the memory occupation can be reduced, an application group with complete and operable functions and a complete, continuous and uniform man-machine interaction interface is provided for a user, and the user experience is greatly optimized.

The utility model relates to electric tricycle technical field, and disclose a kind of oil brake electric tricycle device of emergency starting double system complementary brake, brake pedal drives brake lever, front brake axle rotation, and it is passed to rear brake axle by first foot brake rocker arm, linkage pull rod, second foot brake rocker arm transmission, brake is realized by brake rocker arm acting on rear axle;In sub-brake assembly, sub-brake pull rod is pushed support plate by connecting rod, inner rocker arm, brake pad support is opened brake around connecting axle seat, double system complementary solves the emergency braking problem of main brake failure, and sub-brake has no travel switch design to eliminate half slope start to slip car hidden danger, improves driving safety and control convenience.

The utility model relates to unmanned equipment flight control technical field especially a control device for controlling unmanned equipment flight, including quick detach mechanism, it includes controller body and rocker, the lower end fixed setting of rocker has the first insert block, the lower end of first insert block is inserted and is connected and sets up the fixed block for quick installation, is provided with the clamping limiting assembly for quick dismounting installation on first insert block, secondary fixing mechanism, it includes the vertical sliding slot of opening in the middle part of first insert block, the lower end fixed setting for quick clamping and separation M type limiting slot of vertical sliding slot, M type limiting slot inner chamber sets up the insert limiting assembly for inserting and fixing, and the periphery of insert limiting assembly is provided with the telescopic component for secondary downward pressure separation. The problem that the prior art exists between rocker and controller connection process complicated and inconvenient dismounting has been solved.

The present invention provides a menu bar display method, device and electronic device, which relate to the technical field of vehicle-mounted display applications. The menu bar is hidden in a vehicle-mounted display screen, and a sensing module is arranged around the vehicle-mounted display screen. The method comprises: detecting a target object based on the sensing module, and determining that the target object is located at a first position within a preset distance of the vehicle-mounted display screen; displaying a menu bar corresponding to the first position on the vehicle-mounted display screen, and displaying the menu bar when a user's intention to use is detected, thereby alleviating the technical problem of a lack of application immersion on the vehicle-mounted display screen.

The invention relates to a lower bullet supply omnidirectional wheel infantry robot based on a Robomaster match, and relates to the technical field of robots. Comprising a chassis structure, a holder frame, a rotating structure and a launching structure, the launching structure comprises a launching mechanism, a lower ammunition supply mechanism and an ammunition storage mechanism, the ammunition storage mechanism and the lower ammunition supply mechanism are connected with the holder frame, and the launching mechanism communicates with the ammunition storage mechanism through the lower ammunition supply mechanism; the chassis structure comprises a frame and a wheel set mechanism, and the wheel set mechanism is mounted at the bottom of the frame; the wheel set mechanism comprises a damping system and an omnidirectional wheel set, the damping system comprises a parallelogram suspension and a shock absorber, and the parallelogram suspension is connected with the omnidirectional wheel set through a coupler, a thrust ball bearing and a gasket.
