20140372840 | Method and System for Detecting Errors in the Transfer of Data from a Transmitter to At Least One Receiver - A method for detecting errors in a transfer of data from a transmitter to at least one receiver includes coding the data together with address information identifying the receiver in a series of data packets and transferring the data and the address information using the data packets. The method also includes generating, at the transmitter, a check value for each data packet and transferring the check value with/in the data packet to the receiver. The method further includes comparing, at the receiver, the check value with an expectation value, wherein an error is detected in the event of a deviation. For each data packet to be transmitted, the method includes calculating a number sequence value from the address information using a first calculation rule, generating the check value from the sequence value using a second calculation rule and transmitting the data packet with the check value to the receiver. | 12-18-2014 |

20130038512 | Simultaneous Reproduction of a Plurality of Images by Means of a Two-Dimensional Imaging Matrix - An image reproduction arrangement for simultaneous reproduction of a plurality of has a two-dimensional imaging matrix having the matrix elements arranged in rows and columns. The arrangement has an optical device designed to prevent observation of parts of the images from corresponding viewing angle ranges. The optical device defines a direction in the surface of the imaging matrix which runs parallel to edges of such areas of the imaging matrix which can be seen or cannot be seen from the viewing angle ranges. The imaging matrix represents blocks of matrix elements which are separated from one another in the row direction and column direction by other matrix elements which are not used to represent the image. The blocks each have matrix elements which follow one another in the column direction. The overall height of the matrix elements is greater than the width of the matrix elements. | 02-14-2013 |
20140268527 | IMAGE REPRODUCTION ASSEMBLY HAVING A FRONT PANE FASTENED IN A SPACE-SAVING MANNER - An image reproduction assembly having a two-dimensional image presentation matrix bounded by edges and by means of the matrix elements of which images are presented, fastening elements attached adjacent to edges of the matrix, a front pane fastened to the fastening elements, which is fixed in a plane in front of the image presentation matrix. Each fastening element protrudes beyond the plane of the image presentation matrix and partially beyond the edge of the image presentation matrix transversely to a viewing direction. Fastening elements are arranged along the edges so holes exist between fastening elements and/or adjacent to one or more fastening element. Fastening elements of a first image reproduction assembly can be positioned in holes of other image reproduction assemblies. Fastening elements of image reproduction assemblies adjacent to the first image reproduction assembly can be positioned in holes of the first assembly. Assemblies of image reproduction assemblies are provided. | 09-18-2014 |
