20120205101 | METHOD FOR MAKING RESIN-COATED PROPPANTS AND A PROPPANT - A method for making resin-coated proppants comprising applying epoxy and phenol resins with a curing agent onto the surface of proppants. The epoxy and phenol resins with the curing agent are applied onto the surface of the mix of proppants. The mix of proppants is obtained by blending heavy proppants with bulk density of 1.4 g/cm3 and more, with lightweight proppants with bulk density of less than 1.4 g/cm3. The application of the epoxy and phenol resins is performed at temperatures from 5 to 35. degrees Celsius. | 08-16-2012 |

20100109949 | MOBILE TERMINAL HAVING A HYBRID NAVIGATION SYSTEM AND METHOD FOR DETERMINING A LOCATION THEREOF - A mobile terminal having a hybrid navigation system and a method for determining a location thereof. A satellite navigation system receiver receives satellite data from a satellite. An inertial navigation system measuring device measures inertial data of the mobile terminal. A computing device receives the satellite data from the satellite navigation system receiver and the inertial data from the inertial navigation system measuring device, estimates a location of the mobile terminal using the inertial data, computes a state vector having location information obtained by correcting the estimated location using the satellite data and a state vector correlation error matrix having error information of the state vector, and determines the location of the mobile terminal using the state vector. The computing device uses a state vector correlation error matrix computed in a previous step when computing a state vector correlation error matrix in a current step. | 05-06-2010 |
