  • 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.

  • Patent number: 9652474
    Abstract: A method and a system provide regional content to users by associating data files with geographical properties and matching the geographical property of a data file with the geographical property of the user. The system extracts geographical information from a data file, and associates the data file with a source geographical property corresponding to the extracted geographical information according to a geographical information database. Upon obtaining a user geographical property of a user, the system provides the data file to the user if the source geographical property matches the user geographical property. The method and the system may be implemented using a geographical name lexicon or a geographical name suffix lexicon.

  • Publication number: 20170096196
    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: 20160156511
    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.
