Abstract: Devices, methods, and non-transitory program storage devices are disclosed herein to perform predictive image sensor cropping operations to improve the performance of video image stabilization operations, especially for high resolution image sensors. According to some embodiments, the techniques include, for each of one or more respective images of a first plurality of images: obtaining image information corresponding to one or more images in the first plurality of images captured prior to the respective image; predicting, for the respective image, an image sensor cropping region to be read out from the first image sensor; and then reading out, into a memory, a first cropped version of the respective image comprising only the predicted image sensor cropping region for the respective image. Then, a first video may be produced based, at least in part, on the first cropped versions of the one or more respective images of the first plurality of images.

Abstract: A pump, for example, a centrifugal slurry pump, has a casing (10) with an inlet (12) and an outlet (14). The casing (10) and a separate backliner (28) define a chamber (16) in which an impeller (18) is arranged to be rotated by way of a drive shaft (20) which extends axially with respect to the casing (10). Fine running clearances are defined between the front and rear surfaces of the impeller (18) and the adjacent surfaces of the casing (10) and the backliner (28). In order to compensate for increases of the running clearances, for example, due to erosion, the backliner (28) may be moved axially relative to the casing (10). The backliner (28) is connected to an annular flange (38) which is bolted to an annular flange (36) connected to the casing (10) and the spacing between the flanges (36, 38) may be adjusted by removing one or more shims (40) provided therebetween.
