| 20120030268 | Randomized value generation - A data processing apparatus is provided for producing a randomized value. A cell in the data processing apparatus comprises a dielectric oxide layer and stress voltage circuitry is configured to apply a stress voltage across the dielectric oxide layer of the cell to cause an oxide breakdown process to occur. Oxide breakdown detection circuitry is configured to determine a current extent of the oxide breakdown process by measuring a response of the dielectric oxide layer to the stress voltage and randomized value determination circuitry is configured to determine a randomized value in dependence on the current extent of the oxide breakdown process. | 02-02-2012 |
| 20110212889 | USE OF LEPTIN FOR THE TREATMENT OF FATTY LIVER DISEASES AND CONDITIONS - The invention generally relates to the use of leptin in the treatment of a leptin-responsive disease or condition in a non-lipodystrophic subject. More particularly, the invention is directed to the use of leptin in the treatment of a fatty liver disease in a non-lipodystrophic subject with a relative leptin deficiency. The invention includes methods for the treatment of nonalcoholic steatohepatitis (NASH), alcoholic fatty liver disease (AFLD), and nonalcoholic fatty liver disease (NAFLD) in a non-lipodystrophic subject. The invention includes the treatment of conditions ranging from ectopic lipid accumulation (steatosis) to cirrhosis. | 09-01-2011 |
| 20110207801 | Novel Genes, Compositions, and Methods for Modulating the Unfolded Protein Response - The present invention relates to methods and compositions for modulating the unfolded protein response. The method further relates to methods and compositions for the treatment and diagnosis of protein conformational diseases or disorders, including, but not limited to, α1-antitrypsin deficiency, cystic fibrosis, and autoimmune diseases and disorders. The invention further provides methods for modulating the unfolded protein response by modulating XBP1 mRNA splicing. | 08-25-2011 |
| 20110087450 | Heading Error Removal System for Tracking Devices - Systems are able to reduce or remove slowly-varying drift errors, such as heading errors, rate of rotation errors, and direction of travel errors, to correct the measurements from tracking devices. The systems may be used to remove the slow varying drift errors for gyroscopic tracking device sensors, or other types of sensors used for determining heading, rates of rotation, direction of travel, or position. The systems may be employed in personal dead reckoning systems, or other personnel tracking device, as well as in vehicle tracking devices. The system uses heuristic assumptions to correct for these drift errors, via a feedback loop control having an accumulator responsive to changes in output signals. The accumulator is able to produce a signal that over time compensates for the inherent drift errors on those output signals. | 04-14-2011 |
| 20100258821 | CONCAVE-HEMISPHERE-PATTERNED ORGANIC TOP-LIGHT EMITTING DEVICE - A first device is provided. The first device includes an organic light emitting device, which further comprises a first electrode, a second electrode, and an organic emissive layer disposed between the first and second electrode. Preferably, the second electrode is more transparent than the first electrode. The organic emissive layer has a first portion shaped to form an indentation in the direction of the first electrode, and a second portion shaped to form a protrusion in the direction of the second electrode. The first device may include a plurality of organic light emitting devices. The indentation may have a shape that is formed from a partial sphere, a partial cylinder, a pyramid, or a pyramid with a mesa, among others. The protrusions may be formed between adjoining indentations or between an indentation and a surface parallel to the substrate. | 10-14-2010 |
| 20100247766 | NOZZLE GEOMETRY FOR ORGANIC VAPOR JET PRINTING - A first device is provided. The device includes a print head. The print head further includes a first nozzle hermetically sealed to a first source of gas. The first nozzle has an aperture having a smallest dimension of 0.5 to 500 microns in a direction perpendicular to a flow direction of the first nozzle. At a distance from the aperture into the first nozzle that is 5 times the smallest dimension of the aperture of the first nozzle, the smallest dimension perpendicular to the flow direction is at least twice the smallest dimension of the aperture of the first nozzle. | 09-30-2010 |
| 20100245479 | COMPACT ORGANIC VAPOR JET PRINTING PRINT HEAD - A first device is provided. The first device includes a print head, and a first gas source hermetically sealed to the print head. The print head further includes a first layer further comprising a plurality of apertures, each aperture having a smallest dimension of 0.5 to 500 microns. A second layer is bonded to the first layer. The second layer includes a first via in fluid communication with the first gas source and at least one of the apertures. The second layer is made of an insulating material. | 09-30-2010 |
| 20090244971 | Memory cell structure, a memory device employing such a memory cell structure, and an integrated circuit having such a memory device - A memory cell structure for a memory device is provided, the memory cell structure comprising a read transistor having a floating gate node, a tunnelling capacitor, and a coupling capacitor stack. The tunnelling capacitor is connected to the floating gate node and has a first programming terminal, whilst the coupling capacitor stack is connected to the floating gate node and has a second programming terminal. The coupling capacitor stack comprises at least two coupling capacitors arranged in series between the floating gate node and the second programming terminal, with the coupling capacitor stack having a larger capacitance than the tunnelling capacitor. During a programming operation, a voltage difference is established between the first programming terminal and the second programming terminal to cause charge tunnelling to occur through the tunnelling capacitor, such that after the programming operation a charge is stored in the floating gate node. During a read operation, the read transistor is activated to produce an output signal indicative of the charge stored in the floating gate node. Such a memory cell structure is efficient in terms of area, and can be manufactured using standard CMOS logic manufacturing processes, thereby avoiding some of the complexities involved in the production of more conventional EEPROM and Flash memory devices. | 10-01-2009 |
| 20090213673 | Data processor memory circuit - A memory circuit for use in a data processing circuit is described, in which memory cells have at least two states, each state being determined by both a first voltage level corresponding to a first supply line and a second voltage level corresponding to a second supply line. The memory circuit comprises a readable state in which information stored in a memory cell is readable and an unreadable state in which information stored in said memory cell is reliably retained but unreadable. Changing the first voltage level but keeping the second voltage level substantially constant effects a transition between the readable state and the unreadable state. In use, the static power consumption of the memory cell in the unreadable state is less than static power consumption of the memory cell in the readable state. | 08-27-2009 |
| 20080288227 | Algorithms to predict clinical response, adherence, and shunting with thiopuriness - A method of using a variable set from complete blood counts and blood chemistry panels to generate a machine learned algorithm for determining the effectiveness of thiopurine treatment on inflammatory bowel disease (IBD) patients using CART, boosted trees, random forest classification, RuleFit and/or logistic regression analysis. | 11-20-2008 |
