|20140082264||NAND FLASH STORAGE CHIP CHECKING METHOD AND DEVICE - A NAND flash storage chip correcting method is provided in the present invention. The method can correct one or two bits errors and find a number of bits errors according to the row and column XOR value and Hash value of each page written into the spare area, comparing the data stored in the data area and the computed Hash value of data area to correct one or two bits of errors, thus ensures the accuracy and integrity of the data stored in the NAND Flash chip and reduces the risk of crash of the file system.||03-20-2014|
|20130188326||Security Protection Device and Method - A security protection device includes a cover circuit board comprising at least one inner wiring layer and a base circuit board comprising at least one inner wiring layer. The device further includes a security frame between the base circuit board and the cover circuit board, at least one electrically conductive wire being wound and included within the security frame to form at least one winding protection layer around sides of the security frame. The cover circuit board, the security frame, and the base circuit board form an enclosure enclosing a security zone, and the at least one inner wiring layer within the cover circuit board, the at least one inner wiring layer within the base circuit board, and the at least one electrically conductive wire within the security frame are connectable to a security mechanism configured to detect an intrusion into the security zone.||07-25-2013|
|20100242115||SECURITY COVER - The present invention is available for the field of electronic circuit protection, and provides a security cover for enclosing a protective area on the protected PCB and protecting the components in this area. The security cover comprises a flexible PCB that is folded with a receiving space and an opening in a side in the space. The flexible PCB is covered on the protective area of the protected PCB and encloses the components in the protective area. The flexible PCB triggers the related circuits to remove or destroy the information on the components in this protective area in case of physical attack. The present invention is to enclose the key components on PCB via the flexible PCB with the receiving space so as to prevent the key components from being attacked.||09-23-2010|
|20100103631||SECURITY PROTECTION BOX - The present invention is adapted for field of electronic circuit protection and provides a security protection box, for enclosing the protected region of a protected circuit board in order to protect the elements in the protected region. The security protection box comprises a circuit board. The circuit board with thin center and thick periphery forms a box shape, and has the circuit routing layers. The circuit routing layers trigger the associated circuit to erase or destroy the information in the elements in the protected region when the circuit routing layers are physically attacked. The present invention protects the elements in the protected region through covering the protected region on the protected circuit board with a circuit board having thin center and thick periphery.||04-29-2010|
