20130119987 | Spatially Coincident MRI Receiver Coils and Method For Manufacturing - A magnetic resonance imaging receiver coil provides for high SNR and high uniformity over a range of loading conditions with layers, or stacks, of independent conductive elements. The plurality of layers preload the receiver coil reducing the circuit variation as the subject coupling and loading varies. The preload is such that coil performance, or SNR, is maintained over a large range of impedance variation. This configuration is designed to exceed the performance of single trace coils over a range of impedance consistent with variations associated with different subjects, and may also incorporate coils of different resonance frequencies. | 05-16-2013 |
20130131490 | System and Method for Determining The Presence of a Neurodegenerative Disease Using Magnetic Resonance Elastography - A system and method for analyzing a subject using a magnetic resonance imaging (MRI) system is provided. The technique includes positioning a subject within the MRI system and coupling a driver to the subject to impart vibrational energy to the subject. The technique further includes using the MRI system and in coordination with operation of the driver, acquiring medical imaging data from the subject's brain and deriving stiffness information of the subject's brain from the medical imaging data. A report, such as an image, can be provided indicating the stiffness information of the subject's brain relative to baseline stiffness information to indicate a status of the subject with respect to a neurodegenerative disease. | 05-23-2013 |
20140107467 | System And Method For Improved Efficiency In Magnetic Resonance Elastography - A system and method for generating a magnetic resonance elastography (MRE) report includes a) acquiring MRE data from a subject including positively motion encoded medical imaging data and negatively motion encoded medical imaging data and b) deriving uncorrected difference medical imaging data from the MRE data for a given slice. The method also includes c) filtering the uncorrected difference medical imaging data to create filtered medical imaging data corrected for errors associated with phase ramps occurring during gradient switching used to derive the positively motion encoded medical imaging data and negatively motion encoded medical imaging data, d) generating a corrected difference image for the given slice from the filtered medical imaging data and the uncorrected difference medical imaging data, e) repeating steps b) through d) for each slice reflected in the MRE data, and f) generating a report of elastic properties of the subject from the corrected difference image. | 04-17-2014 |

20100102101 | Paper toweling dispenser apparatus - Toweling dispenser apparatus including a toweling support roller carrying a movable cutter blade. A switch is actuated after a user pulls on toweling to rotate the toweling support roller and transport the toweling. After some rotation of the roller has occurred, an electric switch is closed and energizes an electric motor to drive the roller and reduce the force required by the user to rotate the roller and actuate the cutter blade to sever a towel from the toweling. | 04-29-2010 |
20100301157 | Multi-function paper toweling dispenser - A paper toweling dispenser selectively operable to dispense paper toweling from a roll of paper toweling employing a plurality of alternative operational modes. | 12-02-2010 |
20110133019 | Multi-function paper toweling dispenser - In a toweling dispenser, an electric motor driven toweling support roller and a handle for rotating the toweling support roller are connected by a one-way clutch, which allows the handle to rotate the toweling support roller only in a single direction of rotation when the electric motor does not drive the toweling support roller, the single direction transporting toweling on the toweling support roller to an exit opening of the dispenser. | 06-09-2011 |
20120273605 | Cover actuated roll towel dispense - Toweling dispenser apparatus includes a cover having relatively moveable cover portions. Relative movement caused by pushing one of the cover portions operates through transmission structure to rotate a toweling support drum and move toweling within the interior of the apparatus toward a dispensing position. | 11-01-2012 |
20130026019 | Handle operated switch for paper towel dispenser - Control apparatus for controlling operation of a paper towel dispenser includes control switches and a handle having two relatively movable handle portions rotating when a paper toweling support drum rotates. One of the handle portions has projections which engage the switches when the handle rotates. | 01-31-2013 |
20130193258 | PAPER SHEET MATERIAL DISPENSER APPARATUS - Toweling or other paper sheet material dispenser apparatus includes a sheet material support roller carrying a movable cutter blade. A user pulls on a sheet material tail to rotate the sheet material support roller and transport the sheet material. After the sheet material is substantially or completely severed by a cutter blade on the roller, an electric switch is closed and an electric motor energized to drive the roller and present a new tail to be pulled by a user. | 08-01-2013 |
20130197707 | Apparatus and method for harvesting and storing energy - A system for harvesting and storing energy including photovoltaic structure continuously harvesting energy from an internal lighting system, at least one supercapacitor for receiving and storing electrical energy produced by the photovoltaic structure, and a microprocessor continually powered by the supercapacitor and programmed to activate an electrically operated device when the stored energy in the supercapacitor exceeds a minimum voltage charge level sufficient to maintain operation of the microprocessor. | 08-01-2013 |
