Abstract: A vision testing device includes a light-occluding casing for administering vision tests. A viewing station is coupled to the light-occluding casing so a test subject can see a first digital display housed within the light-occluding casing. A second digital display is external to the light-occluding casing and is configured to receive touch-based input. One or more predetermined vision tests are displayed via the first digital display. The second digital display receives input corresponding to the vision test displayed via the first digital display. The second digital display includes response indicators that can be activated via a swiping motion on the second digital display, and a response is recorded as a result of the swiping motion. Each answer corresponding to a swiping motion is stored and output as a result of the vision test.

Abstract: It is often necessary to securely transfer data, such as authenticators or authorization tokens, between programs running on the same end-user device. The teachings hereof enable the pairing of two programs executing on a given end-user device and then the transfer of data from one program to the other. In an embodiment, a first program connects to a server and sends encrypted data elements. A second program intercepts the connection and/or the encrypted data elements. The second program tunnels the encrypted data elements (which remain opaque to the second program at this point) to a server, using an encapsulating protocol. This enables the server to receive the data elements sent by the first program, decrypt them, and provide them to the second program via return message using control fields of the encapsulating protocol. Once set up, the tunneling arrangement enables bidirectional data transfer.

Abstract: Methods for dolomite mapping using multiscale fracture characterization include using a computer system to receive seismic data for a geographical area. The computer system identifies one or more macroscale fractures located within the geographical area based on a three-dimensional (3D) visualization of the seismic data. The computer system identifies one or more mesoscale fractures located within the geographical area based on a curvature map generated from the seismic data. The computer system identifies one or more microscale fractures located within the geographical area based on an amount of chaotic seismic reflections indicated by the seismic data. The computer system identifies a dolomite distribution of the geographical area based on the one or more macroscale fractures, the one or more mesoscale fractures, and the one or more microscale fractures. A display device of the computer system generates a graphical representation of the dolomite distribution.

Abstract: A method may include obtaining various well logs or various core samples regarding a geological region of interest. The method may further include determining various permeability values, various porosity values, and various dolomite volume fraction values regarding the geological region of interest using the well logs or the core samples. The dolomite volume fraction values may correspond to a percentage of dolomite in a total mineral volume. The method may further include determining, using the porosity values, various permeability thresholds corresponding to various predetermined reservoir qualities. The method may further include generating, using the permeability thresholds, the permeability values, and the dolomite volume fraction values, a reservoir model including various dolomite boundaries defining the predetermined reservoir qualities. The method may further include determining a hydrocarbon trap prediction using the reservoir model.

Abstract: Disclosed is a method for evaluating the vision of an individual under certain brightness conditions, using a screen displaying an image including a background and characters to be deciphered which appear on the background. The method includes the following steps: a step of regulating the brightness of the background of the image; and a step of regulating the brightness of the characters to be deciphered which appear on the image, the two steps being independent from each other so as to obtain the desired contrast between the background and the characters.

Abstract: Among other things, this document describes systems, devices, and methods for improving the mapping of end user clients to content servers. In one embodiment, an intermediary DNS server receives a DNS answer with multiple IP addresses. The intermediary DNS server modifies this answer before passing it on to the end user client—that is the end user client that originally requested name resolution of the hostname. Modification can involve filtering the list to remove low-performing IP addresses, re-ordering the list, blocking certain IPs according to policy, or other things. The intermediary DNS server can be operated by a internet service provider (carrier) or an enterprise, for example, or provided on their behalf by a third party as a service. The modification can be based on knowledge of the client-side network, including the location and connectivity of the end user client.
