Abstract: A method and a system for refreshing a flash memory device are provided. The system mainly includes a host, and a main control unit and a plurality of flash memory units arranged in the flash memory device. The method includes the following steps: providing a performance value of the plurality of flash memory units from the main control unit to the host; providing a refresh command from the host to the main control unit when the performance value is lower than a pre-determined value; and controling the plurality of flash memory units, by the the main control unit, to stop current operations, and executing a refresh operation on the plurality of flash memory units.

Abstract: A memory access speed adjustment method, control device and memory module are provided. The method is for use in controlling a controller of a memory and includes steps of: obtaining a current temperature value of the memory; determining an access speed threshold of the memory according to a continuous variation relation with respect to a difference between the current temperature value and a target temperature value; and adjusting, by the controller, an access speed of the memory according to the access speed threshold.

Abstract: A peer to peer network, a method, a computer program product for a new node joining the network and a computer readable medium are disclosed. The peer to peer network comprises a plurality of nodes and a new node. Each of the nodes has its own partner list. Each of the partner lists records nodes that are able to provide data to the owner of the partner list. The nodes recorded in the partner list are called the partners of the owner of the partner list. When the new node intends to join the network, each of the nodes of the network decides whether to accept the new node according to the number of its partners but not according to a random manner. The stability of the network can be enhanced and the load of the network can be balanced.

Abstract: A multi-function peripheral includes a casing, a scanning module and a printing module. The casing has a recording media path. The scanning module is located on the recording media path for selectively scanning recording media fed into the casing from the recording media path. The printing module also is located on the recording media path for selectively printing the recording media. The recording media are then discharged out of the casing through the recording media path. Thus the multi-function peripheral can reduce the number of elements, simplify replacement of the inkjet cartridge of the printing module, reduce the dimensions, lower the element cost and diminish the complexity of the mechanisms.

Abstract: A pickup mechanism for a business machine. A support shaft is disposed in the business machine. An oscillating arm includes a first end and a second end opposite thereto. The first end is fitted on the support shaft. An inner-rotor type motor is disposed on the second end of the oscillating arm and includes a central rotating shaft extending beyond the inner-rotor type motor. A pickup roller is connected to the central rotating shaft. When the inner-rotor type motor operates, the pickup roller rotates by rotation of the central rotating shaft.

Abstract: A medium category determination method for a multi-function peripheral, which uses an algorithm to enhance the differences in the luminance values of three primary color and the corresponding standard deviations. The luminance values color and the corresponding standard deviations become precise bases for category determination of unknown media. Caused by the coarseness and the colors on the surfaces of different media, these differences under visible light are easily collected by scanning modules. The method scans the unknown medium to obtain the luminance values of three primary colors, calculates the corresponding standard deviations of all luminance values of the unknown medium, enhances the differences among the luminance values and standard deviations among the unknown medium and multiple known media by an algorithm, and finally determines the category of the unknown medium as the category of one known medium.
