Patent number: 11568766Abstract: A fiber Bragg grating (FBG) security component for single-party and multi-party monitoring is provided. The security component includes an optical fiber having a plurality of Bragg gratings. The Bragg gratings provide a spectral response that is randomized based on the manufacture of the security component. For single-party use, the spectral response provides a reproducible spectral signature when interrogated with an optical signal. For multi-party use, each party applies a known optical interrogation signal to the security component and applies an external stress known only to the respective monitoring party. The resulting shift in the spectral signature is unique to each monitoring party, making it extremely difficult to successfully counterfeit the security component's response for all such parties.Type: GrantFiled: April 6, 2021Date of Patent: January 31, 2023Assignee: UT-BATTELLE, LLCInventors: Klaus-Peter Ziock, William R. Ray, James R. Younkin, Brandon R. Longmire

Patent number: 8487993Abstract: Multiple homography transformations corresponding to different heights are generated in the field of view. A group of salient points within a common estimated height range is identified in a time series of video images of a moving object. Inter-salient point distances are measured for the group of salient points under the multiple homography transformations corresponding to the different heights. Variations in the inter-salient point distances under the multiple homography transformations are compared. The height of the group of salient points is estimated to be the height corresponding to the homography transformation that minimizes the variations.Type: GrantFiled: July 29, 2009Date of Patent: July 16, 2013Assignee: UT-Battelle, LLCInventors: Mark F. Cunningham, Lorenzo Fabris, Timothy F. Gee, Frezghi H. Ghebretati, Jr., James S. Goddard, Thomas P. Karnowski, Klaus-peter Ziock

Patent number: 7973276Abstract: The relationship between the high energy radiation imager pixel (HERIP) coordinate and real-world x-coordinate is determined by a least square fit between the HERIP x-coordinate and the measured real-world x-coordinates of calibration markers that emit high energy radiation imager and reflect visible light. Upon calibration, a high energy radiation imager pixel position may be determined based on a real-world coordinate of a moving vehicle. Further, a scale parameter for said high energy radiation imager may be determined based on the real-world coordinate. The scale parameter depends on the y-coordinate of the moving vehicle as provided by a visible light camera. The high energy radiation imager may be employed to detect radiation from moving vehicles in multiple lanes, which correspondingly have different distances to the high energy radiation imager.Type: GrantFiled: July 29, 2009Date of Patent: July 5, 2011Assignee: UT-Battelle, LLCInventors: Mark F.

Patent number: 7592602Abstract: In a vehicle, a single detector plane simultaneously measures radiation coming through two coded-aperture masks, one on either side of the detector. To determine which side of the vehicle a source is, the two shadow masks are inverses of each other, i.e., one is a mask and the other is the anti-mask. All of the data that is collected is processed through two versions of an image reconstruction algorithm. One treats the data as if it were obtained through the mask, the other as though the data is obtained through the anti-mask.Type: GrantFiled: February 22, 2007Date of Patent: September 22, 2009Assignee: Lawrence Livermore National Security, LLCInventor: Klaus-Peter Ziock

Patent number: 6949748Abstract: Imaging of radiation sources located in a subject is explored for medical applications. The approach involves using grazing-incidence optics to form images of the location of radiopharmaceuticals administered to a subject. The optics are “true focusing” optics, meaning that they project a real and inverted image of the radiation source onto a detector possessing spatial and energy resolution.Type: GrantFiled: April 11, 2003Date of Patent: September 27, 2005Assignee: The Regents of the University of CaliforniaInventors: Klaus-Peter Ziock, William W. Craig, Bruce Hasegawa, Michael J. Pivovaroff

Patent number: 5118934Abstract: X-ray/gamma ray imaging apparatus is disclosed for detecting the position, energy, and intensity of x-ray/gamma ray radiation comprising scintillation means disposed in the path of such radiation and capable of generating photons in response to such radiation; first photodetection means optically bonded to the scintillation means and capable of generating an electrical signal indicative of the intensity, and energy of the radiation detected by the scintillation means; second photodetection means capable of generating an electrical signal indicative of the position of the radiation in the radiation pattern; and means for optically coupling the scintillation means to the second photodetection means. The photodetection means are electrically connected to control and storage means which may also be used to screen out noise by rejecting a signal from one photodetection means not synchronized to a signal from the other photodetection means; and also to screen out signals from scattered radiation.Type: GrantFiled: August 3, 1990Date of Patent: June 2, 1992Assignee: The United States of America as represented by the United States Department of EnergyInventors: Charles J.
