The OCT imaging system further includes a beam splitter configured to receive the light from the light source, split the light into a first light portion directed along a sample arm comprising a sample and a second light portion directed along a reference arm comprising a reference mirror, receive a first reflected light portion from the sample arm and a second reflected light portion from the reference arm, combine the first and second reflected light portions to obtain an interference signal at a detector. Further, the OCT imaging system includes a controller having logic configured to perform an auto-focusing process to determine the optimal position for a lens in the sample arm in order to bring the sample into focus.

Patent number: 8843240
Abstract: Systems and methods for loading a steam turbine are provided. A method may include: receiving a turbine loading factor; receiving a current steam turbine exhaust temperature; determining a steam flow ramping rate parameter and a steam temperature ramping rate parameter based at least in part on the turbine loading factor and the current steam turbine exhaust temperature, wherein the steam flow ramping rate parameter and the steam temperature ramping rate parameter are determined based at least in part on an inverse relationship between the steam flow ramping rate parameter and the steam temperature ramping rate parameter. The method may further include controlling at least one of: (a) steam flow to the steam turbine based at least in part on the steam flow ramping rate parameter; or (b) steam temperature to the steam turbine based at least in part on the steam temperature ramping rate parameter.

Patent number: 8842398
Abstract: An apparatus and method for detecting an arc fault using a power conductor on a printed circuit board (PCB), which supplies power from an external power source to electrical components on the PCB by sensing a value indicative of the rate of change of current passing through the power conductor. The apparatus and method may be used for detecting arc faults both internal and external to the PCB.

Patent number: 8842801
Abstract: A rod assembly for a fuel bundle of a nuclear reactor may include an upper end piece, lower end piece and a plurality of rod segments attached between the upper and lower end pieces and to each other so as to form an axial length of the rod assembly. The rod assembly may include an adaptor subassembly provided at given connection points for connecting adjacent rod segments or a given rod segment with one of the upper and lower end pieces. The connection points along the axial length of the rod assembly may be located where the rod assembly contacts a spacer in the fuel bundle. One (or more) of the rod segments may include an irradiation target therein for producing a desired isotope when a fuel bundle containing one (or more) rod assemblies is irradiated in a core of the reactor.

Patent number: 8841267
Abstract: The present disclosure provides non-naturally occurring miR-196a-2 miRNAs and non-naturally occurring miR-204 miRNAs. The non-naturally occurring miRNAs of the disclosure have mature strand sequences distinct from their endogenous counterparts. The disclosure also provides methods of selecting mature strand sequences that function optimally in non-naturally occurring miR-196a-2 miRNAs. The methods and compositions of the disclosure may be used to mediate gene silencing via the RNAi pathway.
