    Abstract: A phase locked loop (PLL) generates a phase locked signal and adjusts a frequency of the phase locked signal according to an incoming signal. The PLL includes an oscillator for generating the phased locked signal and a frequency detection module electrically coupled to the oscillator. The frequency detection module includes a pattern detector for detecting the two regular patterns in the incoming signal, a counter electrically coupled to the pattern detector for calculating the number of periods of the phase locked signal corresponding to the distance between the two regular patterns, and a comparator electrically coupled to the counter for comparing the number of periods with a predetermined value to generate a control signal, and using the control signal to control the oscillator to adjust the frequency of the phase locked loop signal.

    Abstract: A field effect transistor configured for use in high power applications and a method for its fabrication is disclosed. The field effect transistor is formed of III-V materials and is configured to have a breakdown voltage that is advantageous for high power applications. The field effect transistor is so configured by determining the operating voltage and the desired breakdown voltage for that operating voltage. A peak electric field is then identified that is associated with the operating voltage and desired breakdown voltage. The device is then configured to exhibit the identified peak electric field at that operating voltage. The device is so configured by selecting device features that control the electrical potential in the device drift region is achieved. These features include the use of an overlapping gate or field plate in conjunction with a barrier layer overlying the device channel, or a p-type pocket formed in a region of single-crystal III-V material formed under the device channel. The overlapping gate/field plate or p-type pocket extend into the drift region of the device, controlling the electrical potential of the device in a manner that provides the desired control of the electrical potential in the drift region.

    Abstract: The present invention provides a control loop bandwidth adjusting system for adjusting a control loop bandwidth of an optical reproducing device. The optical reproducing device comprises a data signal processing circuit, which uses the control loop bandwidth to process the data signal. The control loop bandwidth adjusting system comprises a control loop bandwidth generator for generating the control loop bandwidth and a control loop bandwidth according to whether a defect signal corresponding to the defect data is received or not. If the control loop bandwidth adjusting module receives the defect data entry signal, the defect data duration signal, and the defect data exit signal, the control loope bandwidth is adjusted to a first bandwidth value, a second bandwidth value, and a third bandwidth value respectively.

    Abstract: Disclosed is a method for converting cellulose in a lignocellulosic biomass. The method provides for a lignin-blocking polypeptide and/or protein treatment of high lignin solids. The treatment enhances cellulase availability in cellulose conversion and allows for the determination of optimized pretreatment conditions. Additionally, ethanol yields from a Simultaneous Saccharification and Fermentation process are improved 5-25% by treatment with a lignin-blocking polypeptide and/or protein. Thus, a more efficient and economical method of processing lignin containing biomass materials utilizes a polypeptide/protein treatment step that effectively blocks lignin binding of cellulase.
