| 20130041508 | SYSTEMS AND METHODS FOR OPERATING ROBOTS USING VISUAL SERVOING - A system and method for providing intuitive, visual based remote control is disclosed. The system can comprise one or more cameras disposed on a remote vehicle. A visual servoing algorithm can be used to interpret the images from the one or more cameras to enable the user to provide visual based inputs. The visual servoing algorithm can then translate that commanded motion into the desired motion at the vehicle level. The system can provide correct output regardless of the relative position between the user and the vehicle and does not require any previous knowledge of the target location or vehicle kinematics. | 02-14-2013 |

| 20080227545 | Apparatus and method for digitization of human motion for virtual gaming - Handheld apparatus and method to provide control over virtual figures and elements within a computer rendered environment. Motion capturing sensors output acceleration vector signals. After digitization and storage of these vector signals into data packets, the packets are wirelessly transmitted to the receiver device. The receiver device transfers the digitized packets to a computer or a video game console. A rendering application resident on the console utilizes the received vector data to move the graphical elements on the display. Unique computation of the acceleration vectors result in realistic and real-time human movement in a computer generated three-dimensional environment. Employment of multiple independent handheld apparatuses provides more precise simulation of human motion in a virtual environment. | 09-18-2008 |

| 20090058417 | Test object for use with diffusion MRI and system and method of synthesizing complex diffusive geometries using novel gradient directions - A test object for use with diffusion MRI and a system and methods of synthesizing complex diffusive geometries. The test object, which includes anisotropic structures, can be used to monitor DTI measures by providing a baseline measurement. Using measurements of the phantom, data characteristic of more complicated diffusive behavior can be “synthesized”, or composed of actual measurements re-arranged into a desired spatial distribution function describing diffusion. Unlike a typical DTI scan, the ADC measurements of the present invention are treated in a “reconstruction” phase as if the gradients were applied in different directions. Given a set of reconstruction directions, a judicious choice of acquisition directions for each reconstruction direction allows for the synthesis of any distribution. | 03-05-2009 |
| 20090190816 | Systems and methods for rescaling image intensities with diffusion MRI to synthesize complex diffusive geometries - A method for scaling MR signal intensity after noise has been removed is disclosed. Because the signal in a DTI series varies with the apparent diffusivity in the direction of an applied gradient, one can multiply image data collected under actual clinical conditions with a spatially-dependent scaling function to synthesize different spatial diffusion distributions, after removal of noise. Recombination of the data with the removed noise preserves the bias in the system. | 07-30-2009 |
| 20090190817 | Systems and methods for parametric mapping for correction of noise -based systematic bias of DTI metrics, using a DTI mapping phantom - A system and method for minimizing, if not completely eliminating, the systematic bias present in an MR system used for DTI is disclosed. A test object or “phantom” of the present invention is scanned with a desired DTI protocol. The eigenvalues measured with the phantom are compared to the actual values that should have been measured, and a parametric map that links measured eigenvalues to actual eigenvalues is calculated, which is applicable to the desired protocol. Future eigenvalue measurements using this protocol can be recalibrated to actual eigenvalues using this map. | 07-30-2009 |
