Patent number: 8279122Abstract: A wireless communication system can include polarization agile antennas to enable adaptation to the polarization characteristics of a changing propagation channel. In one embodiment, a mobile terminal can include one or more polarization-agile antennas, and can select polarization orientations that are preferentially propagated through the changing propagation channel. In another embodiment, a mobile terminal having two polarization-agile antennas can provide spatial diversity, polarization diversity, or combinations of both. Multiple-input multiple-output (MIMO) systems can include polarization-agile antennas to allow for switching between spatial and polarization diversity, combined spatial and polarization diversity, and various Eigen channel decompositions using spatial, polarization, and combined spatial and polarization dimensions. An extended polar normalization provides enhanced fidelity for methods of communications system modeling.Type: GrantFiled: March 27, 2012Date of Patent: October 2, 2012Assignee: University of UtahInventors: David Glen Landon, Cynthia Furse

Patent number: 8269497Abstract: An NMR probe which includes a probe matrix (24) having a void sample (28) volume therein. A conductive coil (16, 26) can be at least partially embedded in the probe matrix (24). By embedding the conductive coil (16, 26) in the probe matrix (24), the fill-factor can be significantly increased. NMR probes can be formed by a method which includes wrapping a conductive wire (16) around a coil form (18) to produce a coil precursor assembly. The probe matrix (24) can be formed around the conductive wire and coil form with a matrix material using any suitable technique such as soft lithography and/or molding. The coil form can be removed from the probe matrix leaving a void sample volume (28) in the probe matrix. Advantageously, the NMR probes of the present invention allow for fill-factors approaching and achieving 100%.Type: GrantFiled: January 4, 2007Date of Patent: September 18, 2012Assignee: University of Utah Research FoundationInventors: James C.

Publication number: 20120084068Abstract: A computing device simulates a test system by defining parameter values to be used to populate certain modeling formulas defining the test system. The defined parameter values correspond to one of the many points defining a domain in which the test system is to be simulated. The simulation iteratively solves the modeling formulas for each unit of the test system model space for each point in the domain in which the test system is simulated. Results for the subjects of interest are calculated at each iteration using the populated modeling formulas. A variance of the subjects of interest is also calculated at each iteration using a correlation coefficient obtained for the subjects of interest. The iterations of defining the parameter values and calculating the value and variance of the subjects of interest in the test system model space continues until all points in the domain have been simulated.Type: ApplicationFiled: September 30, 2010Publication date: April 5, 2012Applicant: University of Utah Research FoundationInventors: Steven M.

Patent number: 7271596Abstract: A technique for testing a signal path while an operational signal is present is disclosed. The technique may be performed without injecting a test signal into the signal path by using an operational signal already present in the signal path.
