  • Publication number: 20190050871
    Abstract: Systems and methods for presenting CRM data. Users may configure what to display on a custom report and how to arrange and display the content (e.g., size, color, theme), so that they can visualize the CRM data the way they want. A data visualization interface may be used to generate the custom report, and may use HTML to specify the CRM data to be displayed and their location on the custom report according to user configuration. The data visualization interface may use JavaScript for specifying the objects and fields users want to query to obtain the CRM data to fill up the custom report. An API may communicate with the JavaScript in the data visualization interface and then query data and objects in the CRM to get a result set. The API may be a unified API which may work across multiple platforms and query various types of database, e.g., iOS, Windows, and the browser for Salesforce online.

  • Patent number: 9954730
    Abstract: The present invention is applicable to and relates to the field of communications technologies, and provides a method for delivering a static route and an ultimate provider edge (UPE). The method includes: reading, by a UPE, a packet; and delivering a corresponding static route according to related information carried in the packet. The present invention avoids problems that when a site is deployed on a large-scale radio access network, a base station cannot operate normally and a data communications device repeatedly performs troubleshooting and debugging on site caused by differences between preliminary data planning and actual site deployment data. A static route is automatically delivered by processing a packet, thereby reducing manpower costs and avoiding occurrence of human errors.

  • Patent number: 9849944
    Abstract: A cargo transfer monitoring system at least comprises at least one vessel motion sensor, one pair of wireless modems, a central data processing unit with decision-making module, a rugged display panel as the operator station, and communication coupling. The cargo transfer operation will be carried out by a crane operator sitting in the crane cabin on the primary vessel. The transfer will take place either from target vessel to primary vessel or from primary vessel to target vessel. The sensor(s) collect the real-time motion of vessels, which is carried over to the central computer through data cable or wireless radio link. The decision-making module predicts the motion of the vessels for a subsequent time period. Based on the predicted value, the decision-making module projects the expected or predicted impact force on the payload if the operation is started at the particular time.

  • Publication number: 20170334792
    Abstract: Novel methods of fabricating porous structures (e.g., nanostructures) and resulting structures are disclosed. The novel methods use precision optics to cure a slurry made from one or more powders mixed with photopolymers. Pore size control preferably is achieved by controlling the powder size and powder loading in the slurry. As the disclosed methods are based on optics to control the thickness preferably without any mechanical movements, extreme tight thickness tolerance, as well as control of the profile structure, may be achieved. The novel disclosed methods are highly-cost effective with shorter manufacturing cycle time compared to conventional methods. Moreover, a supporting substrate may not be required as the resultant structure made by the novel fabrication techniques disclosed herein has enough strength to be free-standing.

  • Patent number: 9813074
    Abstract: Methods, apparatus and articles of manufacture (e.g., physical storage media) to calibrate interpolating string digital-to-analog converters are disclosed. Example methods disclosed herein to calibrate a digital-to-analog converter (DAC) include determining a first calibration codeword based on a first nonlinearity error value measured at an output of the DAC when a most-significant-bit (MSB) portion of an input codeword is applied to an input of the DAC. Such disclosed example methods also include determining a second calibration codeword based on a second measured nonlinearity error value measured at the output of the DAC when a least-significant-bit (LSB) portion of the input codeword is applied to the input of the DAC. Such disclosed example methods further include combining the first calibration codeword and the second calibration codeword to determine a third calibration codeword to be accessed by the DAC to calibrate the output of the DAC when the input codeword is applied to the DAC.
