  • Patent number: 9510157
    Abstract: A system for tracking a mobile resource in a manufacturing site is described. The system includes a transmitter mounted on the mobile resource to transmit a first signal indicative of a location of the mobile resource at the manufacturing site. The system also includes a transceiver disposed at the manufacturing site to receive the first signal via a wireless network and transmit a second signal indicative of a location of the mobile resource and a duration for which the mobile resource is located at the manufacturing site. The system also includes a controller to communicate with the transceiver and a database. The controller is configured to receive the second signal, identify the location of the mobile resource based on the second signal and information in a database, determine location of the mobile resource with respect to a fixed resource, and determine operational characteristics of the mobile resource.

  • Publication number: 20150192919
    Abstract: A method for three dimensional printing of a large sized object is provided. The method includes creating a three dimensional model associated with the object to be printed and analyzing a geometry of the three dimensional model. The method also includes placing seams on a deflated support member to form pathways on the support member such that the pathways are formed based on the analyzed geometry of the three dimensional model. The method further includes introducing a pressurized fluid into the pathways and further inflating the support member to conform to the analyzed geometry. The inflation is done to a predetermined pressurized geometry associated with the support member. The method also includes supporting the three dimensional printing of the object by the inflated support member. The inflated support member is configured to prevent at least one of an overhanging or a collapse of materials of the object prior to solidification.
