Abstract: In a method for determining the visual acuity two spaced outer markings and an orientation marking lying between but not on a straight connecting line are displayed to the user on a display in an individual test as part of a plurality of tests, and the user is to move the orientation marking on the display perpendicularly to the straight connecting line by actuating the device until the user perceives the marking as lying on the straight connecting line. After, the electronic device then registers the effective distance between the orientation marking and the connecting line. At least two tests are carried out in which the outer markings are arranged along the same main axis, and at least the vertical main axis and the horizontal main axis are measured. After the manipulation, the effective distance from the individual tests of the series is used for ascertaining the visual acuity.

Abstract: Historical vehicle telematics data, corresponding to trips known to have been driven by specific persons within a limited pool of potential drivers, may be processed to generate a statistical model that is customized for those persons. Once generated, the custom statistical model may be used to process vehicle telematics data from trips where it is known that the driver was one of the drivers in the pool of drivers, but the specific identify of the driver is not known. Because the statistical model is specifically optimized or designed to distinguish among the drivers in the pool, the model may be more accurate than universal driver identification models.

Abstract: Methods for determining oil-water contact positions and water zone resistivities are provided. In one example, the method may involve performing a 1D inversion on data collected by a resistivity logging tool. Further, the method may involve scanning a resistivity profile of a reservoir generated by the 1D inversion for a boundary position below the resistivity logging tool. Furthermore, the method may involve applying a local residual weighted average on the boundary position to generate an initial estimation of an oil-water contact position and inverting the initial estimation of the oil-water contact to generate water zone resistivity and a modified oil-water contact position. Additionally, the method may involve miming a smoothing local post-processing operation to generate a layered model and performing a 2D inversion on the layered model.
