Abstract: A computer-implemented method, a computer program, and a device for determining a visual performance of an eye of a person are disclosed. The method includes displaying to at least one eye of a person a visual stimulus configured to elicit at least one type of eye movement in the at least one eye of the person with at least one screen; tracking the at least one type of eye movements in the at least one eye of the person with at least one eye tracker; determining the visual performance of the at least one eye of the person by using at least one first piece of information about the at least one visual stimulus and at least one second piece of information about an occurrence of the at least one type of eye movements in the at least one eye of the person with at least one processing unit.

Abstract: The tool for machining bore transitions includes a holder drivable rotatably through at least one rotation, and drivable in an advance stroke and in a return stroke; and a spring wire having at least two resilient arms with overlapping movable free end, the spring wire being bent into a hairpin shape so as to have a stem or bent end portion structured to be inserted and held in the holder and a cutting medium provided on the free ends of the resilient arms for machining the bore transitions. The holder can advantageously be provided with a slot for the stem, threaded bolts which engage between the resilient arms of the spring wire and a spring which spring-loads the side of the spring wire inserted in the slot.

Abstract: A tool for processing holes has a shaft which can be clamped in a drive element for executing a forward stroke into a working position within a hole, a return stroke, and an at least rotating working motion of the tool, two support elements arranged on the shaft, wires clamped at one end of the shaft between the support elements and being sprung bowing away from the shaft in an arc shape, the wires being coated with a cutting medium. One of the support elements is axially adjustable relative to the shaft. The shaft has axially positioned slots distributed on a circumference in two regions axially offset from one another. The shaft also has an axial hole leading out from both ends of the shaft and extending into the regions. The support elements are formed as limit stops inserted in the axial hole and each end just short of an entry of the hole into an area of the slots. The wires have ends extending through the slots and coming to rest on the limit stops.
