Abstract: Aspects concern a method for gathering image training data for training a machine learning model to detect features for vehicle navigation or vehicle control, comprising mounting a camera onto a vehicle or the driver of a vehicle, determining a location of the vehicle, determining a relevancy of the determined location for map data generation or vehicle control and recording a video with the camera if the determined relevancy is above a predetermined threshold and recording single images if the determined relevancy is below the predetermined threshold.

Abstract: Universal joint bushes for universal joints are disclosed, as well as methods of making or treating the universal joint bushes. The universal joint bush may include an outer ring, which has a peripheral layer (R) formed by at least one measure for diffusing an element into regions of the universal joint bush near the surface. The peripheral layer (R) of the outer ring may include nitrogen. A method for producing a universal joint bush having a nitrogen-containing peripheral layer (R) may include preparing a universal joint bush made from a case-hardened steel and diffusing, via a thermochemical treatment, nitrogen into regions of the universal joint bush that are close to the surface in order to form the nitrogen-containing peripheral layer (R). The thermochemical treatment may be carried out in a temperature range of at least 800° C.

Abstract: A universal joint or a pivot pin cross with a universal joint pivot pin. A bearing bush seal is fastened to the universal joint pivot pin and absorbs an axially directed force. A universal joint is to be provided which is simple and can be manufactured inexpensively, which makes no compromises with respect to the sealing effect. For this purpose, a bearing bush seal is provided which deflects an axially directed force into a radial direction. This makes an axial stop at the universal joint pivot pin unnecessary. Moreover, manufacturing the bearing bush seal and the accommodation thereof at the universal joint pivot pin are accomplished in a single manufacturing step.

Abstract: This invention describes an efficient super-resolution method for image enhancement that leverages prior knowledge about the specific task for which detail information is recovered. The particular case of barcode scanning is considered. The barcode localization and decoding algorithm of the present invention employs a subpixel-accurate search algorithm which allows for estimating barcode bit values at a higher resolution than that available in the image data itself. It thus allows for the synthesis of image detail from multiple frames with the result containing more detail than any of the input frames. For efficiency, it leverages special properties of the quadrilateral target object as well as prior knowledge about constant patterns in the barcodes of interest. This allows for real-time software implementations on portable devices such as camera-equipped cell phones where super-resolution helps to overcome some of the typical camera resolution and processing power constraints.

Abstract: A bearing arrangement for a universal joint including a securing ring which is inserted in an annular groove of a universal-joint yoke with a form fit is arranged such that it can be adjusted. In this case, both the securing ring and an associated contact surface on a base of the universal joint bush have a contact surface which rises helically.

Abstract: A universal joint having a spider provided with four staggered journals. A socket having an axial bearing in addition to a radial bearing is associated with each journal. The axial bearing has rolling bodies that are guided between a front surface of the journal and the bottom of the universal joint socket.

Abstract: A universal joint bush for a universal joint of a universal joint shaft. In order to seal an annular gap, which is produced between the journal and the universal joint bush, a sealing ring is provided which encloses radially outwardly directed sealing lips. During assembly of the universal joint bush on the journal, the sealing lips, which are connected directly or indirectly to a radially inwardly directed rim of the universal joint bush, make a venting means possible, through which the air which is enclosed in the inner space of the universal joint bush can escape.

Abstract: The invention relates to a universal joint bush (1) for a universal joint (4) of a universal joint shaft. In order to seal an annular gap (5) which is produced between the journal (3) and the universal joint bush (1), a sealing ring (2) is provided which encloses radially outwardly directed sealing lips (6, 7, 8). During assembly of the universal joint bush (1) on the journal (3), the sealing lips (6, 7) which are connected directly or indirectly to a radially inwardly directed rim (14) of the universal joint bush (1) make a venting means (17) possible, through which the air which is enclosed in the inner space of the universal joint bush (1) can escape.

Abstract: The invention relates to a universal joint comprising a spider provided with four staggered journals. A socket comprising an axial bearing in addition to a radial bearing is associated with each journal. Said axial bearing comprises rolling bodies that are guided between a front surface of the journal and the bottom of the universal joint socket.

Abstract: A bearing arrangement for supporting a universal joint trunnion in an outer cup includes a radial bearing having cylindrical rolling elements disposed between the trunnion and the outer cup, and a resistance member made of a material to allow elastic deformation and bearing upon a confronting surface area of an end surface of the trunnion. The resistance member and the trunnion are hereby so configured either alone or in combination as to form a large lubricant reservoir. Disposed at a distance to the end surface of the trunnion is a stop member to define an axial gap, whereby the stop member inhibits an axial movement of the trunnion after the trunnion has moved in axial direction to close the gap.

Abstract: A displacement joint includes an outer joint part having circumferentially spaced recesses to form tracks. A tripod is mounted in fixed rotative engagement to a driveshaft and includes a tripod spider which has spherical arms spaced circumferentially in symmetric disposition for engaging the recesses. Roller bearing assemblies are fitted in the outer joint part to support the tripod arms, with each tripod arm guided by two roller bearing assemblies. Each roller bearing assembly has a bearing shell, which receives the tripod arm, rolling members fitted with clearance in a cage and disposed between the track of the outer joint part and a contact surface of the bearing shell. The cage is guided by shoulders of the outer joint part, which laterally bound the track, wherein the cage has opposite collars in parallel relationship to the shoulders for providing an axial stop for the rolling members and the bearing shell.
