| 20100017777 | Method and apparatus for synthesizing a hardware system from a software - A method and an apparatus take software source code to synthesize a hardware platform for running the software. The method determines which processor is suitable for running the code and meeting the performance parameters determined by the user. The method also determines which hardware devices are accessed by software. If the hardware target is a semiconductor chip, the invention selects the appropriate IP and creates an HDL description of the chip. If the hardware target is a printed circuit board, the invention creates a schematic or netlist that includes the appropriate microprocessor, the various semiconductor chips, and the necessary interconnections. | 01-21-2010 |

| 20100133098 | Methods and Devices for Concentration and Purification of Analytes for Chemical Analysis Including Matrix-Assisted Laser Desportion/Ionization (MALDI) Mass Spectrometry (MS) - Analytical methods and devices are disclosed for separating low abundance analytes by electrophoretically driving the analytes through a sieving matrix to first remove high molecular weight species. Subsequently the remaining low abundance analytes are electrophoretically focused onto a capture membrane where the analytes become bound within a small capture site. After this step the capture membrane may be allowed to dry and then attached to a conductive MALDI sample plate. | 06-03-2010 |

| 20080285036 | Determination of Light Absorption Pathlength in a Vertical-Beam Photometer - Disclosed are photometric methods and devices for determining optical pathlength of liquid samples containing analytes dissolved or suspended in a solvent. The methods and devices rely on determining a relationship between the light absorption properties of the solvent and the optical pathlength of liquid samples containing the solvent. This relationship is used to establish the optical pathlength for samples containing an unknown concentration of analyte but having similar solvent composition. Further disclosed are methods and devices for determining the concentration of analyte in such samples where both the optical pathlength and the concentration of analyte are unknown. The methods and devices rely on separately determining, at different wavelengths of light, light absorption by the solvent and light absorption by the analyte. Light absorption by the analyte, together with the optical pathlength so determined, is used to calculate the concentration of the analyte. Devices for carrying out the methods particularly advantageously include vertical-beam photometers containing samples disposed within the wells of multi-assay plates, wherein the photometer is able to monitor light absorption of each sample at multiple wavelengths, including in the visible or UV-visible region of the spectrum, as well as in the near-infrared region of the electromagnetic spectrum Novel photometer devices are described which automatically determine the concentration of analytes in such multi-assay plates directly without employing a standard curve. | 11-20-2008 |
