  • Publication number: 20150346711
    Abstract: A method for editing a position of a selected design element in a constraint network. The method includes receiving the selected design element in a geometric model from a user, searching a database for a positioning group related to the selected design element, and adding the selected design element and the positioning group related to the selected design element into a work collection. The method then includes searching the database a second time for reference positioning groups and reference design elements referenced by constraints of the positioning group and design elements in the work collection and adding the reference positioning groups and the reference design elements discovered by the second searching into a context collection. The method then further includes loading all the constraints for the positioning groups and the design elements which were added to the work collection.

  • Patent number: 9080985
    Abstract: The present invention relates an optical sensor. In particular, the present invention relates to an optical sensor for detecting chemical components in a fluid. The present invention comprises two or more sensors, each being configured to detect one or more chemicals in a fluid, or one or more properties of the fluid, and two or more light sources. Each sensor is associated with one light source, and each sensor is configured to emit or reflect light in response to light from the light source incident on the sensor. The emitted or reflected light is dependent upon the presence of a chemical or a property of the fluid. The two or more light sources and two or more sensors are arranged around a single light detector, which detects the color and/or intensity of the light being emitted or reflected by the sensor. Data from the light detector is passed to a remote processor for processing.

  • Patent number: 7385572
    Abstract: A display for an electronic device may be calibrated and corrected for pixel-to-pixel variations in intensity. Radiation-sensing elements used for the calibration are not incorporated as circuit elements within the pixel circuits and may lie outside the pixels. Waveguides, reflectors, or the like may be used to optically couple the radiation-emitting elements of the pixels to the radiation-sensing elements. The radiation-sensing elements may be part of an apparatus separate from the electronic device or may be embedded within the electronic device. Many different methodologies may be used for correcting intensities to achieve better homogeneity in intensity among the pixels within a display.
