A method is described for operating a computer system comprising a computer and a display unit, wherein a reference pattern is formed based on input value fed into the computer, wherein image signals for the display unit are generated based on the input value, wherein the image signals fed to the display unit are detected, wherein the detected image signals are subjected to a pattern recognition to provide a recognized pattern, and wherein the recognized pattern is compared with the reference pattern.

A digital medium environment is described for automatic design discrepancy reporting of discrepancies between an actual display and its intended design. In one example, a design validation system generates a design screen model for a design screen, based on an object included in the design screen and at least one display property that defines a visual appearance of the object. The design validation system then identifies an application object that has a similar visual appearance to the defined visual appearance of the object of the design screen model. The design validation system additionally determines that a discrepancy exists between a display of the design screen model object and the application object. The design validation system also determines a value by which the at least one property of the application object is to be adjusted and outputs the value to adjust the at least one display property of the application object.

A tiling display apparatus includes a plurality of display modules connected to one another through a first interface circuit and a second interface circuit and a set board receiving a defect occurrence and position signal, generated in a broken-down module of the plurality of display modules, from the broken module through the first interface circuit in a first period, generating a defect recognition completion signal in a second period succeeding the first period, and transferring the defect recognition completion signal to the broken-down module through the second interface circuit in the second period.

A method for the safe visualization of a safety-relevant information includes the steps of: for all possible states of at least one variable input parameter, decomposing a safe visualization of the at least one variable input parameter into its safe base elements (31); for each of the decomposed safe base elements, enumerating and storing a set of all possible states of safe base element visualization (32); and for each of the decomposed safe base elements, transmitting the set of all possible states of safe base element visualization to a target system that provides safe visualization at runtime (33).

Disclosed herein are technologies directed to a feature ideator. The feature ideator can initiate a classifier that analyzes a training set of data in a classification process. The feature ideator can generate one or more suggested features relating to errors generated during the classification process. The feature ideator can generate an output to cause the errors to be rendered in a format that provides for an interaction with a user. A user can review the summary of the errors or the individual errors and select one or more features to increase the accuracy of the classifier.

A redundant display system includes a communication network, display devices, first and second display nodes, a control node, a monitoring node, and a system node. Display devices each include first and second display inputs. First display nodes include first display outputs, each connected to a first display input to display digital content on display devices and can be assigned the role of main or redundant display node. Second display nodes include second display outputs, each connected to a second display input to display digital content on display devices and can be assigned the role of main or redundant display node. The control node sends digital content to the display nodes. The monitoring node collects operational information of the display nodes and generates alerts if the operational information indicates a failure. The system node receives alerts from the monitoring node and reassigns roles of the display nodes based on the alerts.

A method displays a course of a process of at least one railway safety unit. While using at least one device control, process data supplied by the at least one railway safety unit, are converted by dual-channel processing into first and second image data of the course of the process to be displayed. The image data are output to be displayed on a data display unit. In order to simplify the displaying of the course of the process, a pair of display spectacles having a first and a second display is used as a data display unit. The first display displays a first representation of the first image data delivered thereto that is visually detectable by the right eye, and the second display displays a second representation of the second image data delivered thereto that is visually detectable by the left eye.

A bit-by-bit error correction technique is disclosed that divides each bit transmission into an acknowledgment phase, an error correction phase, and a transmission phase.
