Publication number: 20190293943Abstract: Example systems and methods are described that help increase the situational awareness of a user of a helmet, such as a motorcycle helmet. One or more cameras are physically coupled to the helmet, where each camera includes a lens and an associated image sensor. Each camera is configured to generate a video feed, which is presented to a user on a display. The video feed represents a field-of-view around the helmet, and may be projected onto a surface, such as the visor of the helmet, thereby enabling enhanced situational awareness for the user of the helmet.Type: ApplicationFiled: June 13, 2019Publication date: September 26, 2019Inventors: Marcus Daniel Weller, Liang Guan, Andrew Wei Tam

Patent number: 9594141Abstract: An MR imaging system uses multiple RF coils for acquiring corresponding multiple image data sets of a slice or volume of patient anatomy. An image data processor comprises at least one processing device conditioned for, deriving a first set of weights for weighted combination of k-space data of the multiple image data sets for generating a calibration data set comprising a subset of k-space data of composite image data representing the multiple image data sets. The image data processor uses the calibration data set in generating a first MR image data set, deriving the parameters of a probability distribution in response to the first set of weights and the first MR image data set and deriving a second set of weights and second MR image data set together using the probability distribution.Type: GrantFiled: October 3, 2012Date of Patent: March 14, 2017Assignees: National Institutes of Health (NIH), U.S. Dept. of Health and Human Services (DHHS), The United States of America NIH Division of Extramural Inventions and Technology Resources (DEITR), The General Hospital Corporation, Siemens Healthcare GmbHInventors: Daniel Weller, Leo Grady, Lawrence Wald, Vivek K Goyal

Patent number: 9588207Abstract: A system for parallel image processing in MR imaging comprises multiple MR imaging RF coils for individually receiving MR imaging data representing a slice of patient anatomy. An MR imaging system uses the multiple RF coils for acquiring corresponding multiple image data sets of the slice. An image data processor comprises at least one processing device conditioned for, deriving a first set of weights for generating a calibration data set comprising a subset of k-space data of composite image data representing the multiple image data sets. The at least one processing device uses the calibration data set in generating a first MR image data set, deriving a second set of weights using the calibration data set and the generated first MR image data set and uses the second set of weights in generating a second MR image data set representing a single image having a reduced set of data components relative to the first composite MR image data set.Type: GrantFiled: September 14, 2012Date of Patent: March 7, 2017Assignees: National Institutes of Health (NIH), U.S. Dept. of Health and Human Services (DHHS), The United States of America NIH Division of Extramural Inventions and Technology Resources (DEITR), Siemens Healthcare GmbHInventors: Daniel Weller, Leo Grady, Lawrence Wald, Vivek K Goyal

Publication number: 20160110615Abstract: A situational awareness system is disclosed herein for providing heads-up display to a user on a moving vehicle. The display is focused at an ocular infinity in order to prevent accommodation lag in the user's comprehension. A super wide-angle (e.g., 170 degree to 210 degree) rear-view camera provides rearward looking video imagery to the user, which may be digitally processed and enhanced. Additional information is optionally provided in the display, including maps, turn by turn directions, and visual indicators guiding the user for forward travel. Additional information is optionally provided by audio. One embodiment comprises a full-face motorcycle helmet with a see-through micro-display that projects a virtual image in-line with the helmet-wearer's field of view. A second embodiment comprises a unit that projects a virtual image on a windshield in the operator's field of view.Type: ApplicationFiled: November 12, 2015Publication date: April 21, 2016Inventors: Marcus Daniel Weller, Mitchell Ryan Weller

Patent number: 8991893Abstract: A profile element for connecting a vehicle pane to a water draining chamber includes a U-shaped snap-in recess formed by a bearing rib and a resilient leg disposed below the bearing rib. At an entrance into the snap-in recess, the bearing rib protrudes downward towards the resilient leg and the resilient leg protrudes upward towards the bearing rib so as to define an engagement aperture into the snap-in recess between an upper-most part of the protrusion of the resilient leg and a lower-most part of the protrusion of the bearing rib. A detent element is disposed in the snap-in recess behind the engagement aperture in an insertion direction of a rib of the water draining chamber.Type: GrantFiled: November 6, 2013Date of Patent: March 31, 2015Assignee: Elkamet Kunststofftechnik GmbHInventors: Wolfgang Platt, Michael Ortmueller, Daniel Weller

Patent number: 8823374Abstract: An MR imaging system uses the multiple RF coils for acquiring corresponding multiple image data sets of the slice. An image data processor comprises at least one processing device conditioned for, generating a composite MR image data set representing a single image in a single non-iterative operation by performing a weighted combination of luminance representative data of individual corresponding pixels of the multiple image data sets in providing an individual pixel luminance value of the composite MR image data set. The image data processor reduces noise in the composite MR image data set by generating a reduced set of significant components in a predetermined transform domain representation of data representing the composite image to provide a de-noised composite MR image data set. An image generator comprises at least one processing device conditioned for, generating a composite MR image using the de-noised composite MR image data set.Type: GrantFiled: December 15, 2011Date of Patent: September 2, 2014Assignees: Siemens Aktiengesellschaft, The General Hospital CorporationInventors: Daniel Weller, Vivek K Goyal, Jonathan Rizzo Polimeni, Leo Grady

Patent number: 8628137Abstract: A profile element for connecting a vehicle pane to a water draining chamber includes a first segment affixable to the vehicle pane. A second segment has, at an upper portion, a bearing rib having at least one seal configured to be disposed at a lower edge of the vehicle pane and, at a lower portion, a snap-in recess configured to receive rib of the water draining chamber through an engagement aperture which is delimited in the insertion direction by a lower-most surface of the bearing rib and an upper-most surface of the resilient leg. A detent element is disposed in the snap-in recess so as to facilitate inserting the rib of the water draining chamber in an insertion direction into the snap-in recess and present a larger resistance to extracting the rib from the snap-in recess in an extraction direction opposite the insertion direction.Type: GrantFiled: April 30, 2009Date of Patent: January 14, 2014Assignee: Elkamet KunststofftechnikInventors: Wolfgang Platt, Michael Ortmüller, Daniel Weller
