  • Patent number: 8874910
    Abstract: The present invention provides an encryption method in which the encryption device stores data to be encrypted received via the input/output interface in its own memory, converts the data to be encrypted in the memory into a format required by the output device and transmits the converted data to the output device via the management interface, and the output device outputs the received information. The present invention also provides an encryption device for implementing the above method. The encryption device determines whether confirmation information has been received from a management interface, encrypts the data to be encrypted in the memory if the answer is positive, while performs no encryption or prompting to input correct confirmation information if the answer is negative. With the present invention, the user is allowed to view the contents to be actually encrypted, thereby avoiding such a case as signature counterfeiting or tampering.

  • Patent number: 8717065
    Abstract: A system and method are provided for transmission of data bits across a data bus. To reduce power usage, noise, or some combination of the two, the data bus utilizes differential transmission using a three level signal in which a reference signal signifies no difference between input bits. Before the signals are transmitted an analysis is made to choose which one of a set of predetermined polarity reversal combinations is advantageous to encode the data bits. The data bits are so encoded and a formatting value F associated with the chosen polarity reversal is differentially transmitted with the encoded bits over the data bus. The three level differential signal is received at the far end of the bus, the encoded bits are recovered and decoded with use of F. The system and method achieves up to N bits transmitted per N data lines.

  • Publication number: 20120258561
    Abstract: In embodiments of the present invention an undoped amorphous, nanocrystalline or microcrystalline semiconductor layer and a heavily doped amorphous, nanocrystalline, or microcrystalline semiconductor layer are formed on a monocrystalline silicon lamina. The lamina is the base region of a photovoltaic cell, while the amorphous, nanocrystalline or monocrystalline layers serve to passivate the surface of the lamina, reducing recombination at this surface. In embodiments, the heavily doped layer additionally serves as either the emitter of the cell or to provide electrical contact to the base layer. The undoped and heavily doped layers are deposited at low temperature, for example about 150 degrees C. or less with hydrogen dilution. This low temperature allows use of low-temperature materials and methods, while increased hydrogen dilution improves film quality and/or conductivity.
