Publication number: 20240080374Abstract: Embodiments disclosed herein relate to systems and methods for providing a smart cache. In embodiments, a variable time to live (TTL) may be calculated and associated with data as it is stored in a cache. The variable TTL may be calculated based upon reputation and/or category information related to the source of the data. The reputation and/or category information may include TTL modifiers for adjusting the TTL for data from a particular data source that is stored in the cache. In further embodiments, a feedback method may be employed to update reputation and/or category information for a particular data source.Type: ApplicationFiled: November 9, 2023Publication date: March 7, 2024Inventors: Hal Case Lonas, JR., Thomas W.

Patent number: 11864300Abstract: The electron beam is typically dynamically steered after its generation on the path to the target. The steering is performed by one or more source coils. These coils produce the magnetic field outside the vacuum vessel allowing air/water/oil cooling to remove undesired heat. The magnetic field is then picked up inside the vacuum vessel with pole pieces and guided towards the region where the magnetic field is needed to steer the electron beam.Type: GrantFiled: April 23, 2021Date of Patent: January 2, 2024Assignee: Carl Zeiss X-ray Microscopy, Inc.Inventors: Claus Flachenecker, Thomas A.

Publication number: 20230289835Abstract: Methods and systems for forecasting demand for items across multiple channels are disclosed. In some implementations, multi-channel demand forecasting may be performed on a per-item, per-location basis, by selectively generating item-location forecasts for each item and location within a supply chain for each channel, or disaggregating a chain level forecast on a per-item basis to each location. Particular selection of an appropriate model, and selective training of models, allows for efficient computation of such forecasts across a large supply chain with thousands of locations and hundreds of thousands, or millions, of items for which forecasts are generated.Type: ApplicationFiled: May 18, 2023Publication date: September 14, 2023Applicant: Target Brands, Inc.Inventors: DUANE SIZEMORE, GREGORY THOMAS CASE, JACOB MICHAEL MELVIN LUBY, DANNY BROOK TANNER

Patent number: 10335104Abstract: A multi energy, such as dual-energy (“DE”), x-ray imaging system data acquisition and image reconstruction system and method enables optimizing the image contrast of a sample. Using the DE x-ray imaging system and its associated user interface applications, an operator performs a low energy (“LE”) and high energy (“HE”) x-ray scan of the same volume of interest of the sample. The system creates a low-energy reconstructed tomographic volume data set from the set of low-energy projections and a high-energy tomographic volume data set from the set of high-energy projections. This enables the operator to control the image contrast of selected slices, and apply the information associated with optimizing the contrast of the selected slice to all slices in the low-energy and high-energy tomographic data sets. This creates a combined volume data set from the LE and HE volume data sets with optimized image contrast throughout.Type: GrantFiled: July 22, 2015Date of Patent: July 2, 2019Assignee: Carl Zeiss X-ray Microscopy, Inc.Inventors: Thomas A.

Patent number: 10297048Abstract: A segmentation-and-spectrum-based metal artifact reduction (MAR) system and method is applied in polychromatic X-ray CT system that uses a priori knowledge of high-Z metals in samples which contribute the primary artifacts at a known x-ray energy spectrum. Using a basis materials decomposition, the method solves the problem of reducing or eliminating metal artifacts associated with beam hardening using only a single scan of the sample performed at selected x-ray energy.Type: GrantFiled: October 28, 2016Date of Patent: May 21, 2019Assignee: Carl Zeiss X-Ray Microscopy, Inc.Inventors: Zhifeng Huang, Thomas A.

Patent number: 10169865Abstract: An x-ray imaging system data acquisition and image reconstruction system and method are disclosed which enable optimizing the image parameters based on multiple tomographic volumes of the sample that have been captured using an x-ray microscopy system. This enables the operator to control the image contrast, for example, of selected slices, and apply the information associated with optimizing the contrast of the selected slice to all slices in two or more tomographic volume data sets. This creates a combined volume with optimized image contrast throughout. Also, the system enables navigation within the volumes through functional annotation, improvements in volume registration and improvements in noise suppression both within the volumes and within slice histograms of the sample.Type: GrantFiled: October 17, 2016Date of Patent: January 1, 2019Assignee: Carl Zeiss X-Ray Microscopy, Inc.Inventors: Thomas A.

Patent number: 8068579Abstract: A process to determine the porosity and/or mineral content of mineral samples with an x-ray CT system is described. Based on the direct-projection techniques that use a spatially-resolved x-ray detector to record the x-ray radiation passing through the sample, 1 micrometer or better resolution is achievable. Furthermore, by using an x-ray objective lens to magnify the x-ray image in a microscope configuration, a higher resolution of up to 50 nanometers or more is achieved with state-of-the-art technology. These x-ray CT techniques directly obtain the 3D structure of the sample with no modifications to the sample being necessary. Furthermore, fluid or gas flow experiments can often be conducted during data acquisition so that one may perform live monitoring of the physical process in 3D.Type: GrantFiled: April 9, 2009Date of Patent: November 29, 2011Assignee: Xradia, Inc.Inventors: Wenbing Yun, Michael Feser, Andrei Tkachuk, Thomas A.
