The method further includes machining the rock sample to expose physical faces that correspond to the identified digital planes, performing scanning electron microscope (SEM) imaging of the physical faces to generate two-dimensional (2D) SEM images of the physical faces, and performing image processing on the SEM images to determine a material property associated with each of the rock fabrics. | 2021-11-11 |

20210349043 | Method and System For The Analysis Of Biological Material and Use Of Such A System - A method for the analysis, in particular for analysis by dynamic difference calorimetry (DSC), of biological material, in particular blood, urine, sweat or skin tissue, with the steps of: introduction of a sample with a patient's biological material onto a sensor of a measuring device; acquisition of measured values by means of the measuring device; sending the measured values to an evaluation device, which communicates with the measuring device; assessment of the patient's state of health with the aid of data structures characterizing the state of health on the basis of the measured values by means of the evaluation device, on which a first application software instance is performed; and visualization or audio-visualization of the state of health on a display. The present invention further creates a system for the analysis of biological material and a use of such a system. | 2021-11-11 |
20210349044 | INTEGRATED CIRCUIT PACKAGE THAT MEASURES AMOUNT OF INTERNAL PRECIOUS MATERIAL - Integrated circuit package (ICP) with: (i) stored information pertaining to an amount and/or value of precious material present in the ICP; and (ii) sensor for detecting an amount of precious material present in the ICP. In some embodiments the ICP is embedded in a smart card for use with a smart card reader system that can communicate data to and/or from the ICP. | 2021-11-11 |
