A data storage system having data locking and unlocking functions and a method therefor are provided. The data locking and unlocking method includes: when a used capacity of a storage device is equal to or greater than a first threshold, locking a plurality of folders of the foregoing storage device; preventing the folders from being unlocked when the used capacity is greater than or equal to a second threshold; unlocking the locked folders according to a first unlock signal when the used capacity is less than the first threshold; and unlocking the locked folders according to a second unlock signal when the used capacity is between the first threshold and the second threshold. The foregoing second threshold is greater than the first threshold.

The invention provides a computer system and a method for accessing virtual machine. The computer system comprises a host operating system installed with a host driver and a virtual machine. The virtual machine comprises a hypervisor and a guest operating system. When the host operating system is intended for accessing the virtual machine, it will issue at least one access instruction to the hypervisor of the virtual machine via the host driver. The guest operating system of the virtual machine receives the access instruction from the hypervisor via a guest driver, and accesses a guest application program, a real hardware, and/or a virtual hardware according to the indication of the access instruction so as to generate an access result. Finally, the guest operating system of the virtual machine is able to transmit the access result to the host operating system.

A method of improving multi-type barcode recognition efficiency using continuous sampling is applicable to a barcode recognition apparatus. According to the method, each barcode type is given with a corresponding weight value, and a total weight threshold is set in the barcode recognition apparatus. A barcode pattern is sampled with a limited number of times, and each sampled image sample is only compared with a part of the supported barcode types. When the comparison matches, a weight value is assigned to the matched barcode type, and the weight value is accumulated to acquire a total weight value of the matched barcode type. When comparison of all image samples is finished, the barcode type with the total weight value reaching the total weight threshold is the barcode type of the barcode pattern, and a recognition result of the barcode pattern is output according to the barcode type.

Method of improving the barcode recognition efficiency using continuous sampling, computer readable medium, and barcode recognition apparatus

A barcode recognition method is applicable to a data processing apparatus. According to the barcode recognition method, after the data processing apparatus is turned on, a control module loads and initializes a barcode recognition program from a data storage device, and then switches the barcode recognition program to background execution. The control module continuously monitors whether a trigger event occurs to the data processing apparatus. When the trigger event occurs, the control module switches the barcode recognition program to foreground execution. When the barcode recognition program is in foreground execution, an image capture module captures at least one image frame, for the control module to recognize. The control module derives barcode information, so as to obtain a recognition result. After the control module outputs the recognition result to other application programs by simulating keystrokes, the control module switches the barcode recognition program to background execution.
