Abstract: The disclosure relates to a planetary roller screw having: a nut arranged on a threaded spindle and divided crosswise to a spindle axis into two nut parts; planetary rollers arranged between the threaded spindle and the nut distributed over the circumference, the planetary rollers intermeshing with the nut parts and with the threaded spindle; a rotatingly driven planetary roller carrier arranged on the threaded spindle, in pockets of which, arranged distributed over the circumference, the planetary rollers are mounted, held at a distance in the circumferential direction, so as to be rotatable about the planetary roller axis; and a housing in which the planetary roller carrier is rotatably mounted. A pre-loading device is provided in order to adjust an axial pre-load between the housing and the planetary rollers.

Abstract: Various embodiments and implementations of graph-neural-network (GNN)-based decoding applications are disclosed. The GNN-based decoding schemes are broadly applicable to different coding schemes, and capable of operating on both binary and non-binary codewords, in different implementations. Advantageously, the inventive GNN-based decoding is scalable, even with arbitrary block lengths, and not subject to typical limits with respect to dimensionality. Decoding performance of the inventive GNN-based techniques demonstrably matches or outpaces BCH and LDPC (both regular and 5G NR) decoding algorithms, while exhibiting improvements with respect to number of iterations required and scalability of the GNN-based approach. These inventive concepts are implemented, according to various embodiments, as methods, systems, and computer program products.

Abstract: An indirect view system (100) for a vehicle is provided with at least a capture unit (10) adapted for capturing image data of at least one area of view around the vehicle, at least a control unit (20) which is adapted for processing the images captured by the capture unit, and at least one reproduction (30) which is adapted for reproducing the area of view. The view system has a first setting (1) for showing the area of view and at least a second setting (2) for showing the area of view. The first setting (1) uses predetermined image parameters, and the at least second setting (2) uses image parameters which are changed in view of the first setting (1). The first setting (1) and the at least second setting (2) are usable in an at least partial low light intensity vehicle environment.

Abstract: To produce a paused MPEG coded video stream from an original MPEG coded video stream, an I frame is extracted from the original stream, and a Group of Pictures for a “pause” (a pause GOP) is constructed containing the extracted I frame, some “frozen” frames, and padding. Each “frozen” frame is a P frame that repeats the I frame. When a pause is requested in the original stream, a seamless transition is made from the I frame to the pause GOP, and the pause GOP is played in a loop until a resume is requested. To resume, the pause GOP is completed and a seamless transition is made to continue in the original stream from the I frame where the pause had begun.

Abstract: Predictive analysis is performed upon encoded digital motion video (such as an MPEG Transport Stream) to facilitate real-time splicing. The predictive analysis includes estimation of upper and lower bounds of the data levels in a decoder's video and audio buffers for splicing in such a way as to prevent buffer overflow and underflow. This enables buffer management techniques including padding or stuffing, micro-restamping, freeze or repeat of frames, skip or drop of frames, alignment of audio with video. The predictive analysis also includes analysis of the structure of the encoded audio including audio access units (AAUs) and compression windows (AFs), prediction in the compressed domain of initial conditions of the decoder buffer levels for every single Elementary Stream (ES) component of a Transport Stream (TS), and identification of valid splicing In Points and Out Points based on the predicted buffer levels without any special encoder.
