Abstract: A system and method include identification of a future fault period and a future fault amount associated with a component, determination of production characteristics of the component, generation of a multi-dimensional vector representing the future fault period, the future fault amount and the production characteristics, searching of a vector database of multi-dimensional vectors to identify a second multi-dimensional vector similar to the first multi-dimensional vector and first actions corresponding to the second multi-dimensional vector, and automatic execution of the first actions to resolve the future fault period and the future fault amount associated with the component.

Abstract: A cylindrical covering cap for an eyepiece tube, the eyepiece tube having a conical soft eyecup, includes, in a cylindrical interior of the covering cap: two mutually opposite segment regions having a segment region inside radius that is greater than an inner aperture radius of the covering cap; and at least two mutually opposite segment surfaces, which may be circumferentially spaced so that the locations of the segment surfaces are approximately symmetric about a segment region axis that passes through a center of each of the segment regions. A shortest distance from each segment surface to a cylinder axis may be smaller than the inner aperture radius of the covering cap, and the inner aperture radius of the covering cap may be configured to adapt to a larger outside radius of the conical eyecup. The segment surfaces may be substantially flat or have a substantially cylindrical curvature.

Abstract: The centering device for a mechanical probe comprising a driver and two restoring member acting thereon in opposite directions, wherein only one, possibly multipart, stop is provided for a first restoring member. In the position of rest, the first restoring member lies against the stop exerts, at least near the position of rest, a restoring force twice as great as that exerted by the second restoring member. Springs or fluid pistons are provided as restoring members. They can briefly exert a shaking force on the driver.
