Abstract:
Disclosed is apparatus for processing an encrypted data stream within a computer system adapted to receive the encrypted data stream from a data storage device. A data output device is coupled to a computer system and has a plurality of data output areas. An encrypted data stream is transferred from a data storage device to the data output device, the encrypted data stream being for output to one of the plurality of data output areas. The encrypted data stream is received and decrypted to produce a clear data stream for output to one of the plurality of data output areas. A decryption means receives a decryption key from the computer system, the decryption key relating only to the encrypted stream associated with the one of the plurality of data output areas.
Abstract:
An improved printed circuit board capable of being received by two different types of connector panels is disclosed. The printed circuit board includes a main board portion, and a breakaway board portion. The main board portion includes a first connector. The breakaway board portion is coupled to the main board portion utilizing perforations. The breakaway board portion includes a second connector. The breakaway board portion is capable of being completely detached from the main board portion. The main board portion is electrically coupled to the breakaway board portion utilizing a flexible ribbon cable. The printed circuit board is capable of being received by either a first or a second type of connector panel. The first type of connector panel includes a first connector receptacle and a second connector receptacle disposed in a first configuration. The first connector receptacle is capable of receiving the first connector, and the second connector receptacle is capable of receiving the second connector when the breakaway board portion remains attached to the main board portion. The second type of connector panel includes a third connector receptacle and a fourth connector receptacle disposed in a second configuration. The third connector receptacle is capable of receiving the first connector, and the fourth connector receptacle is capable of receiving the second connector when the breakaway board portion is detached from the main board portion.
