The embodiment of the invention provides a handwriting input method, a handwriting input device, a handwriting input system and a receiver. The method comprises the following steps of: calculating the X axis position information of a light spot acquired by using at least one optical positioning sensor and the Y axis position information of the light spot acquired by the at least one optical positioning sensor to obtain the coordinate information of the light spot, wherein the optical positioning sensor comprises a complementary metal oxide semiconductor (CMOS) optical positioning sensor; acquiring the planar track data of the light spot according to the coordinate information; and transmitting the planar track data to the receiver, so that a control host computer acquires corresponding handwritten information or wipes the handwritten information according to the planar track data received by the receiver. Due to the adoption of the method, the device, the receiver and the system, inputting of the handwritten information and wiping of corresponding information by a user can be realized simply, conveniently and correctly and the cost is saved.

The invention discloses a preparation device of a polymer information material that is easy to recycle and can be erased and written repeatedly, and relates to the technical field of polymer information materials. The wall is fixedly connected with a mounting plate, the upper end side wall of the mounting plate is provided with a placement slot, the printing body is placed in the placement slot, the inner side wall of the placement slot is provided with a mounting slot, and a positioning slot is installed in the mounting slot mechanism, the lower end side wall of the positioning mechanism is fixedly connected with a pull rod, the lower end side wall of the mounting plate is provided with a through groove, the pull rod penetrates through the through groove and extends to the lower part of the mounting plate, and the lower end side wall of the mounting plate is provided with a through groove. A through groove is provided, and the fixing of the printing body is realized through the cooperation between the positioning mechanism and the placing groove, thereby avoiding the shaking of the printing body during the erasing process, and facilitating the erasing work.

The invention provides polyacid based erasable paper and a preparation method therefor and belongs to the technical field of erasable paper. The polyacid based erasable paper is used for solving the technical problems of the existing erasable paper that the existing erasable paper is unstable during discoloration, the color retention time is short, materials are toxic and the price is expensive. The method comprises the steps: mixing a polyacid solution and an alcoholic solution so as to obtain a mixed solution, adding the mixed solution into a quartz tank, and irradiating the mixed solution with a high-voltage mercury lamp so as to obtain a reducing type polyacid solution; and then, adding polyethylene glycol into the reducing type polyacid solution so as to obtain a polyethylene glycol reducing type polyacid solution, smearing cellulose filter paper with a polyethylene glycol solution, the polyethylene glycol reducing type polyacid solution and the polyethylene glycol solution sequentially, and carrying out drying respectively at the temperature of 40-90 DEG C, thereby obtaining the polyacid based erasable paper. The invention also provides the polyacid based erasable paper. Chinese characters, letters and digits obtained through writing and printing the erasable paper provided by the invention are clear and can be kept to be free of obvious change for at least three months.

The embodiment of the invention discloses a display module manufacturing equipment, a manufacturing method, and a display module. The process equipment of the display module includes: an image generator, including a first interface and a second interface; a lighting adapter board, the lighting adapter board is electrically connected to the first interface, and the lighting adapter board is used for transmitting The display signal and power signal sent by the image generator; the measuring point fixture, one end of the measuring point fixture is electrically connected to the second interface, and the measuring point fixture is used to transmit the memory erase sent by the image generator delete command. Compared with the prior art, the embodiment of the present invention reduces the time consumption of the display module in the module section and improves the production capacity of the display module.

The invention relates to a method for erasing data in the used firmware area of ​​a Western Digital hard disk, which is characterized in that it comprises the following steps: 1) when erasing the used firmware area of ​​a Western Digital hard disk, the ATA standard protocol instruction set and hard disk factory custom instructions 2) When erasing a Western Digital hard drive with a reserved area, first restore the disk capacity, and then use standard APIs to overwrite and write data to the reserved area sector by sector , to achieve erasure. The invention adopts the factory-defined instruction set and the ATA standard protocol instruction set to realize the data erasure of the used firmware area of ​​the Western Digital hard disk. The erasing method is simple and effective, and can be widely used in the field of data erasure of hard disk data.

The invention discloses a wood imitation walnut wood dipping device for furniture production, relates to the technical field of furniture production, and solves the problem that in the existing wood dipping process, a large number of workers are required to participate in the operation process, and the labor load of the staff is relatively large, cumbersome to operate, and relatively low production efficiency, including the base; the front end of the base is fixedly connected with a set of dipping drive parts; the upper part of the base is connected with a set of transmission devices; the upper and lower parts of the clamping slider are respectively It is hingedly connected with two sets of clamping struts; the top of the base is fixedly connected with two sets of erasing driving parts; the top of the base is rotatably connected with a group of multi-sets of erasing parts. The invention automatically realizes a series of actions such as clamping the wood, automatically immersing in the dye pool, removing it, draining it, erasing the excess dye, turning it over, and loosening it, which greatly simplifies the labor of workers, saves labor, and is easier to operate , save time and greatly improve work efficiency.
