Abstract: A method for mapping functionally related brain regions of a subject. The method includes receiving a structural brain image and a dataset of resting-state functional MRI (rs-fMR1) three-dimensional (3D) image frames of a brain of the subject includes 3D image frames of the subject's brain over time. A functional connectivity map identifying groupings of functionally connected voxels is overlaid on the structural brain image. Spontaneous brain activations associated with each voxel in a grouping of functionally connected voxels are time-correlated with spontaneous brain activations in one or more other voxels in the grouping of functionally connected voxels. A reference location map for a pre-defined resting state network is generated, including reference information output. The reference location map includes brain reference locations that are informative of the one or more resting-state networks to assist a user in identifying the resting state network of the functional connectivity map.

Abstract: A method of making modular micro-optical systems of great flexibility and adaptability. A substrate is formed with a relief pattern, optical components such as optical fibers are added, another relief pattern is formed, partially through the optical components, and additional components are added, some coupling with the first components. A third relief pattern is formed, further modifying the substrate surface and the optical components already mounted, and further optical components are added, whereby optical signals can be coupled, modulated, transmitted, detected and switched, among others. The method can be employed to form tactile sensors which may be used with robotic manipulators.

Abstract: This invention concerns devices for optical measurement of torsion of a rotating shaft. The measurement system can readily be installed to monitor existing equipment because it requires only that a band consisting of alternating high and low reflectivity regions be placed on the shaft at the locations to be measured. The band may be applied as an adhesive tape, among other possibilities. One sensor head is located to correspond to each band. Each sensor head projects light onto the corresponding band, then collects the light reflected by the high reflectivity region(s) of the band. The phase displacement between the intensities of the reflected light at two or more sensor heads may be used to determine torsion on the rotating shaft.
