  • Patent number: 10663279
    Abstract: Metal film thickness can be determined using the sheet resistance, resistivity, and temperature coefficient of resistivity for the metal film. Variation in film thickness measurements caused by resistivity can be reduced or eliminated. A probe head may be used for some of the measurements of the metal film. The probe head can include a temperature sensor used during sheet resistance measurements. A wafer on a chuck is heated, such as using the chuck or the probe head, for the measurements.

  • Patent number: 10578476
    Abstract: A three dimensional (3D) printing system includes an ink cartridge providing ink to a printhead and a controller. The ink cartridge also includes a flag material and a sensor component. The ink has a low dielectric constant and defines an upper surface having a vertical position defining an ink level. The flag material has a high dielectric constant and is disposed upon the upper surface of the ink. The sensor component includes a vertical arrangement of electrodes proximate to the ink. The controller is coupled to the sensor electrodes and is configured to: (1) scan sensor electrodes to determine a capacitance between adjacent pairs of electrodes, (2) identify at least one pair of electrodes having a peak capacitance value relative to capacitance values of remaining pairs of electrodes, and (3) estimate the ink level based upon the identification.

  • Publication number: 20200003014
    Abstract: A completions bit for use in a wellbore includes: a shank having a coupling formed at an upper end thereof; a body mounted to a lower end of the shank; and a cutting face forming a lower end of the bit. The cutting face includes: a blade protruding from the body; a tangentially oriented leading cutter mounted to a bearing face of the blade adjacent to a leading edge of the blade at an inner portion of the cutting face; and a radially oriented leading cutter mounted to the bearing face of the blade in proximity to the leading edge thereof at an outer portion of the cutting face.

  • Publication number: 20190345507
    Abstract: The invention provides methods and compositions for identifying transgenic seed that contain a transgene of interest, but lack a marker gene. Use of an identification sequence that results in a detectable phenotype increases the efficiency of screening for seed and plants in which transgene sequences not linked to a gene of interest have segregated from the sequence encoding a gene of interest.

  • Publication number: 20190343447
    Abstract: A cognitive platform is disclosed that is configured for either or both of assessing or enhancing the cognitive abilities of an individual based on implementing one or more navigation task(s) in an environment. A first task is rendered that requires the individual to rely on allocentric navigation capabilities to navigate in the environment based on a first set of views of portions of the environment rendered at the user interface. A second task is rendered that requires the individual to rely on egocentric navigation capabilities to navigate in the environment. An indication of a cognitive ability in the individual can be generated based on the difference in the individual's performance at the first task as compared to the second task.

  • Publication number: 20190216392
    Abstract: Example systems, methods, and apparatus, including cognitive platforms, are provided for computing performance metrics of an individual based at least in part on user interaction(s) with computerized tasks and/or interference and at least one physiological measure of the individual, where the performance metric provides an indication of the cognitive abilities of the individual. The apparatus can be coupled to at least one physiological component to perform the physiological measurement of the individual. The apparatus also can be configured to adapt the tasks and/or interferences to enhance the individual's cognitive abilities.

  • Patent number: 10346140
    Abstract: A method for model-based design of safety-critical software is disclosed. The method includes receiving natural-language software requirements, developing a specification model by implementing either semantic modeling or graphical modeling, applying formal requirements analysis to the specification model, auto generating requirements based and robustness test cases from the specification model, developing a design model based on the specification model, applying test cases to the design model, auto-generating source code using the design model, verifying the source code using both test cases and static analysis technology, and compiling executable object code from the verified source code. If a result of the analysis of the software specification or design models is not satisfactory then adjusting the specification or design model to correct any inconsistency, and repeating applying the analysis and test cases.
