A cable core for a cable, in particular, for an induction cable that includes multiple such cable cores which have a conductor that is interrupted in the longitudinal direction at specified longitudinal positions at multiple separation points, thereby forming two conductor ends. An insulating intermediate piece is provided for connecting the conductor ends, and the conductor ends are arranged on both sides of the intermediate piece. The conductor and the intermediate piece are surrounded together by a continuous insulating jacket in order to form the cable core. In a preferred concept, a respective intermediate piece is arranged between the two conductor ends by two adapter elements. In another preferred concept, a respective intermediate piece, in particular, a ceramic intermediate piece, is connected directly to two conductor ends. A cable is formed from a plurality of such cable cores.

Method for producing a cable core for a cable, in particular for an induction cable

A cable, in particular an induction cable, extends in a longitudinal direction along a longitudinal axis and is provided for laying in a pipe. A laying aid is mounted on the cable. The laying aid is formed so that the cable can be rotated about the longitudinal axis during laying. The cable is laid by a method for laying the cable which extends in a longitudinal direction, in which the laying aid is provided and the cable is laid in the longitudinal direction. The cable is rotated about a longitudinal axis extending in the longitudinal direction during laying.

Cable, in particular induction cable, method for laying such a cable and laying aid

An induction cable contains a plurality of cable conductors each having a conductor strand surrounded by insulation. The conductor strand contains a plurality of conductor sections which are spaced apart in the longitudinal cable direction at resonance dividing points by insulating intermediate pieces. The induction cable furthermore has a coupling device on which a plurality of the conductor strands are separated forming coupling ends at coupling positions. The coupling ends are connected to each other via the coupling device. A simple providing and installing of the induction cable and a simple replacement of damaged cable parts is thus enabled.

Adjustment of an eyeglass lens or a pair of eyeglasses by means of an individual brightness-dependent centering of an eyeglass lens. In particular, a method for adjusting an individual eyeglass lens for at least one eye of an eyeglass wearer, including: defining an individual usage situation which comprises at least one target brightness value for the light to be captured by the at least one eye; determining a position of the pupil in at least one direction of view of the at least one eye which occurs or is expected at the at least one target brightness value; determining a reference point of the eyeglass lens, in which the eyeglass lens effects a required correction of individual refraction data for the at least one direction of view; on the basis of the determined individual value of the pupil position, providing and arranging the eyeglass lens in such a manner that the at least one reference point of the eyeglass lens is arranged in front of the at least one eye of the eyeglass wearer.

An optical visual aid is disclosed that assists an observer looking at an object through at least one spectacle lens. The optical visual aid has a dioptric power matched to an eye of the observer for at least one viewing direction. The dioptric power is composed of a plurality of dioptric power components. A first dioptric power component of the plurality of dioptric power components has a best possible corrective power for the eye of the observer at a defined distance of the object from the corneal vertex of the eye for the viewing direction. At the same time, a further dioptric power component of the plurality of dioptric power components has an additional astigmatic, partly corrective power for the viewing direction for the eye of the observer at the defined distance.

A system for stereoscopic visualization of image information includes a display device defining a display area for displaying a left and a right partial image. The display device displays the left partial image to a left eye of an observer focused on the display area in a first viewing direction using a left observation beam path and the right partial image to the right eye in a second viewing direction using a right observation beam path. The system includes a vision assist through which the left and right observation beam paths pass. The vision assist sets a beam course for the left and right viewing observation beam paths wherein, starting from the left and right eyes in a direction toward the display area, a perpendicular distance between the left and right observation beam paths decreases to a minimum at a finite distance from the display surface.
