Patent number: 8717065Abstract: 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.Type: GrantFiled: July 31, 2012Date of Patent: May 6, 2014Inventor: Yonghua Liu

Publication number: 20120258561Abstract: 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.Type: ApplicationFiled: April 11, 2011Publication date: October 11, 2012Applicant: TWIN CREEKS TECHNOLOGIES, INC.Inventors: Jian Li, Venkatesan Murali, Yonghua Liu, Dong Xu
