Intelligent flash U disk having function of mouse and implementation method thereof

Abstract

The invention discloses an intelligent flash U disk having the function of a mouse and an implementation method thereof. The intelligent flash U disk is characterized by comprising a fingerprint sensor for sensing the moving direction and the click movement of fingers and acquiring fingerprint images, a flash memory chip for storing user materials and application programs, a USB (universal serial bus) adapter for data transmission and a USB controller connected among the fingerprint sensor, the flash memory chip and the USB adapter, wherein the USB controller receives sensing signals from the fingerprint sensor, calls software programs in the flash memory chip, outputs the converted control signals to a computer through the USB adapter, thereby realizing the operational function of a mouse. By the connection of one USB adapter with the universal serial bus controller, the invention integrates the functions of a flash memory, the mouse, a joy stick and even an electronic ferule, provides convenience for users to carry computer peripherals, and saves the limited USB port sources of the computer device. Besides, the invention combines a fingerprint encryption technology, thereby improving safety for saving materials and using the computer.

Description

technical field [0001] The present invention relates to a memory device, in particular to a multi-application external memory device controlled by a computer through a universal serial bus controller. Background technique [0002] With the popularization of computers and the continuous expansion of application fields, especially the rapid increase in the proportion of notebook computers, handheld PDAs and various game consoles that need to be equipped with storage devices, flash memory U disks (abbreviated as U disks or USB flash drives) are becoming more and more necessary for users. accessories for electronic peripherals. It has the well-known advantages of small size, large storage capacity, strong compatibility, and easy to carry. And mouse, game joystick and electronic pointer have also been standardized or commonly used peripherals of computer. Especially for notebook computer users to travel and use, they usually need to carry the above-mentioned multiple different ...

AI Technical Summary

Problems solved by technology

Especially for notebook computer users to travel and use, they usually need to carry the above-mentioned multiple different devices in order to use these different functions; especially these devices are generally connected to the computer through a universal serial bus controller (USB), and each occupies a number of Limited USB connectors (ports) not only waste valuable computer resources, but also cause great inconvenience to users for carrying and assembling

The data in the conventional flash memory U disk lacks security protection. When the computer plugged into it is connected to the network, the flash U disk is easily invaded and sheltered by computer viruses, burying hidden dangers for its extended use on other computers

In addition, the mouse in the usual sense generally adopts optical or mechanical principles as the most commonly used computer accessories, but no matter what kind of principle the mouse is used, it must be used with a support object (such as a desktop) as an aid, thus limiting the use of the mouse. Arbitrary

For example, patients who have been bedridden for a long time or who are accustomed to using computers in bed, because the mouse is difficult to find a suitable support surface, it has caused great inconvenience to the use of computers; Personnel are busy between computer operations and electronic pointer instructions, which greatly limits the efficiency of meetings
