  • Publication number: 20240136178
    Abstract: Various embodiments disclosed herein provide for several methods of fabricating p-type semiconductors with industrially relevant hole mobilities that are back end of the line (BEOL) compatible. A first method of fabrication includes forming a buffer layer on a substrate, forming a palladium oxide layer over the buffer layer, annealing the palladium oxide layer, and then forming a cap layer over the palladium oxide layer, then cooling the stack, wherein each step is performed at a variety of predefined temperatures. Each of the substrate, buffer layer and cap layer can be magnesium oxide. A second method includes forming a palladium oxide layer over a titanium dioxide substrate, annealing the stack, and then cooling the stack, all performed at a different variety of predefined temperatures.

  • Patent number: 8490412
    Abstract: A personal environment appliance and a vent for a personal environment appliance are provided. The appliance includes at least one thermoelectric module over at least one inlet port. The appliance further includes at least one main outlet port spaced from the at least one inlet port and at least one waste outlet port spaced from the at least one inlet port. The appliance further includes at least one filter between the at least one inlet port and the at least one thermoelectric module. The vent includes a plurality of first tubular conduits generally parallel to one another and each first tubular conduit having a ratio of the length divided by the width, The vent further includes a plurality of second tubular conduits generally parallel to one another and having a ratio of the length divided by the width. The plurality of second tubular conduits generally surrounds the plurality of first tubular conduits.

  • Publication number: 20120111386
    Abstract: In some embodiments, an integrated power generation system includes a primary power source supplying power to a primary power user, a thermoelectric power generator system thermally coupled to a heat source, and an electronic controller unit. In certain embodiments, an electronic controller unit monitors the power output of the primary power source and operatively connects the thermoelectric power generating system to the primary power user when one or more power usage factors occurs. One power usage factor that can occur is the power output of the primary power source falling below a threshold power level.

  • Publication number: 20090125248
    Abstract: Described is a system for analysis and visualization of genomic data. The system allows a user to select at least one individual sample. The sample has chromosomal data representing a genome with a chromosome and also includes chromosomal measurements of at least one event at a particular location on the chromosome. A frequency of event is generated based on the selected sample. The frequency of event is a frequency of occurrence of the event in the selected sample. At least one annotation can be selected that includes chromosomal region specific information as related to the chromosome. Finally, the chromosomal data, the annotation, and the frequency of event on a display can all be simultaneously displayed, thereby allowing a user to view chromosomal region specific information with respect to a particular chromosomal event.

  • Patent number: 7317820
    Abstract: A digital image processing-based system and method for quantitatively processing a plurality of nucleic acid species expressed in a microarray are disclosed. The microarray is a grid of a plurality of sub-grids of the nucleic acid species. The system includes a scanner that has a digital scanning sensor that scans the microarray and transmits from an output a digital image of the microarray, and a computer that receives the digital image of the microarray from the scanner and then processes the digital image, identifying each of the microarray's sub-grids.

The processor then detects in each of the sub-grids a center-representing pixel of a signal of a chemical material and an approximate radius of the signal. Then, the processor segments the signal and calculates a characterizing measure for the segmented signal.
