A system and method for authentication including verifying a password is disclosed. In one embodiment, the authentication system includes a first storage unit to store an authentication sequence, a read-only memory unit to store an authentication algorithm, and a second storage unit. A microcontroller is coupled to the first storage unit, the read-only memory unit, and is configured to be coupled to and uncoupled from a host. The microcontroller is configured to execute the authentication algorithm to verify a password with the authentication sequence, and to send an access request to a web server via the host if the authentication algorithm has verified the password with the authentication sequence.
摘要:
A portable storage device for storage of data. The portable storage device comprises a first non-volatile memory of a first character; a second non-volatile memory of a second character, the second character being different to the first character; and a controller for determining to which of the first and second non-volatile memory the data is to be sent. The determining is based on a defined relationship between the first and second non-volatile memories, the defined relationship being buffer or backup.
摘要:
An authentication system (10) to verify a password is provided. The authentication system includes a first storage unit (16) to store an authentication sequence (24) and a read-only memory unit (18) on which an authentication algorithm (26) is programmed. A microcontroller (20) is coupled to the first storage unit, the read-only memory unit and a web server. The microcontroller receives the password and executes the authentication algorithm to verify the password with the authentication sequence. A second storage unit (22) is coupled to the microcontroller to store data from the web server. Access to a second storage unit is permitted by the microcontroller only if the password has been verified.
摘要:
A portable data storage device is disclosed that includes an interface (3) for enabling the portable data storage device to be used for data transfer with a host computer (5), and an interface controller (2) for controlling the interface (3). There is also a master controller (7) for controlling the writing of data to and reading of data from a non-volatile memory (8, 9). The non-volatile memory is at least one single level cell (SLC) flash memory (8) and at least one multiple level cell (MLC) flash memory (9). The at least one single level cell flash memory (8) and at least one multiple level cell flash memory (9) are able to operate simultaneously for improving the speed of operation over onl multiple level cell flash memory.
摘要:
An apparatus and method of modular manufacturing process for a transmitter, receiver and/or transceiver is disclosed. The modular process assembles an array of optoelectronic devices to an array header to form an optoelectronic array package. Once the optoelectronic array package is assembled, it is tested and verified the functionality and alignment between the optoelectronic devices and optical fibers. The optoelectronic array package is subsequently coupled to an optical lens array to form an array optical subassembly. After the array optical subassembly is tested, it is coupled to an optical fiber connector to form an optical module. The optical module is then tested to verify its functionality and alignment.

摘要:
A portable memory device is provided that is capable of easy connection to a personal computer via a universal serial bus (USB) port, IEEE 1394 (i.e., firewire) or similar port. Included in the portable memory device is a compression/decompression engine capable of compressing and decompressing data. Data residing on a personal computer or other host platform is compressed by the engine and saved to the memory of the portable memory device. Compressed data is retrieved and decompressed by the engine and transmitted to the personal computer for use by the user. Embodiments of the present invention thus provide a highly convenient system and apparatus for users to access and save larger quantities of data to a relatively small device.
