  • Publication number: 20120140669
    Abstract: A method in a communication network node for testing a capacity of a communication network comprising the communication network node is provided. The communication network node communicates with a plurality of user equipments on downlink and uplink channels over an air interface. The communication network node generates (201) artificial load in a traffic model converter unit comprised in the communication network node, using a traffic model. After reserving (202) a number of physical resource blocks to said generated artificial load, said traffic model converter unit in the communication network node sends (203) information about physical resources that are available for real user equipment load to a scheduler within the communication network node. The scheduler schedules (204) physical resource blocks for said real user equipment load.

  • Patent number: 8158377
    Abstract: A method of biosensor-based detection of toxins comprises the steps of providing at least one time-dependent control signal generated by a biosensor in a gas or liquid medium, and obtaining a time-dependent biosensor signal from the biosensor in the gas or liquid medium to be monitored or analyzed for the presence of one or more toxins selected from chemical, biological or radiological agents. The time-dependent biosensor signal is processed to obtain a plurality of feature vectors using at least one of amplitude statistics and a time-frequency analysis. At least one parameter relating to toxicity of the gas or liquid medium is then determined from the feature vectors based on reference to the control signal.

  • Publication number: 20120068996
    Abstract: A method for rendering 3D content in a safe mode includes receiving images to be rendered in a 3D format, and detecting, in the received images, at least one image having a 3D content creation or conversion error that creates an uncomfortable 3D effect to a user. The method may also include transitioning to a safe mode, under which 3D enhancement is performed to the detected at least one image to avoid the uncomfortable 3D effect, and rendering the 3D enhanced image for display.

  • Publication number: 20110234811
    Abstract: Improving color calibration, and similar operations, by generating an optimal raw RGB color chart, in the raw RGB domain, for an imaging device with a given type of image sensor, such as for a digital still camera. Calibration is performed in response to a constraint which takes into account the spectral sensitivity of the image sensor used on the camera as well as spectral reflectance and spectral radiance of multiple illuminants. Calibration is performed using the raw RGB color chart which is illuminant independent and image sensor specific and which can match the calibration performance of known calibration standards, such as Macbeth 24.

  • Patent number: 7852380
    Abstract: A signal processing system includes: defining a nonlinear function; defining a set of requirements for an output signal; obtaining an input signal; applying a cubic polynomial fitting to approximate the nonlinear function and provide an approximated nonlinear function; assigning a set of fitted polynomial parameters to the approximated nonlinear function; transforming the input signal with the approximated nonlinear function to provide a transformed signal; modifying the transformed signal by adjusting the set of fitted polynomial parameters to provide a modified signal meeting the set of requirements for the output signal; and outputting the modified signal.

  • Publication number: 20100231725
    Abstract: The color calibration using colored rays method achieves illuminant independence in calibrating digital still cameras. A constraint is developed using matrix-vector operations and properties of the Kronecker product. The constraint ensures similar calibration performance between colored rays set and the Macbeth ColorChecker. An optimization scheme using orthogonal non-negative matrix factorization with the new constraint is able to obtain the optimal colored rays set. Then, by acquiring an image of the optimal colored rays set, a camera is able to determine an adjustment matrix for color calibration. Experimental results show that compared to traditional calibration approach for digital still cameras, the colored rays approach gives smaller color error under various evaluation illuminants with only one shot needed.

  • Publication number: 20090080004
    Abstract: A color chart for color calibration of imaging devices that has nearly identical calibration performance as the Macbeth ColorChecker or another set of reference colors, but with substantially fewer color patches. For example, the color chart has similar 2nd order statistical characteristics, auto-correlation matrix and major principal components as the Macbeth ColorChecker. The color chart is developed by applying Orthogonal Non-negative Matrix Factorization (ONMF) to the set of reference colors, using non-negativity and smoothness constraints to achieve physically realizable colors and using orthogonality constraints to obtain similar statistical properties to that of any input set of reflectances including, but not limited to, the Macbeth ColorChecker. Seven colors provide nearly identical calibration performance to that of twenty-four colors in the Macbeth ColorChecker.

  • Publication number: 20080098492
    Abstract: The invention relates to the field of crop selection and crop breeding, particularly to selection methods for breeding colony varieties of crops involving self-pollination and normal cross-pollination. Selection methods include crossing male parents with female parents to obtain crop populations, wherein the female parents are individual plants in a segregation population or self-crossed descendants of early segregation generations, said segregation population obtained by hybridizing pairs of parental plants with different desired characteristics to produce population F1, and then hybridizing pairs of F1 one more time. The male parents are homozygous breeding lines, varieties, F1, heterozygous plants in the segregation generations or individual plants produced in the same manner as for the female group.

  • Publication number: 20050080373
    Abstract: An apparatus and a method is disclosed comprising one or more treatment chambers that may treat the blood of a patient in a minimally invasive way outside of the patient's body. Inside the chamber, the blood may be treated with heat, drugs, mechanical waves, electromagnetic waves, and material beams. In order to further minimize the side effect of treatments, the blood may first be separated into blood components. The treatments may then be applied only to those blood components that actually contain abnormal and cancerous cells that need to be killed.
