A device and to a method for isolating a trigger signal for a test system of a LiDAR sensor, having an optical element, which is arranged in a signal pat of the trigger signal before a converging lens or a trigger detector and which is designed to allow the trigger signal to pass and to at least partially absorb a back reflection, in particular reflected off a surface, of the trigger signal that has passed through the optical element. A test system for a LiDAR sensor is also provided.

A system for testing at least a first automatic control device via a plant model includes: a first subsystem; and a second subsystem which is spatially separated from the first subsystem. The plant model comprises an executable first model code and an executable second model code. The first subsystem comprises a first time-signal processing component configured to electronically assign a first time signal (Ts) from a global time source to a first event. The first model code is configured to provide a first calculation result based on the first event. The second subsystem comprises a second time-signal processing component configured to electronically assign a second time signal (Ts) from the global time source to a second event. The second model code is configured to provide a second calculation result based on the second event.

Apparatus and method for testing an automatic control device

The invention relates to a position-fixing arrangement for use in printed circuit boards, preferably for mechanically determining the position of optical couplers. According to the invention, hollow cylinders are contained in a printed circuit board, parallel to the surface of the same. Said hollow cylinders are opened with a slit that is cut in from the surface and the inner wall of the cylinders fixes positioning pins of the couplers in place. The invention also relates to a corresponding production process.

The invention relates to a method for computationally determining optical properties of a channel waveguide, according to which, for an incident ray entering an entrance surface, the distribution of intensity over an emergence surface is determined by adjoined partial rays that possibly split up. From an incident partial ray striking the outer surface, a predetermined algorithm determines a reflected main ray and, in so far as it is necessary according to the ensuing course of events, determines a number of scattered rays of a higher order, which depict partial rays and are recursively traced further. Each partial ray is either a primary ray or a secondary ray. When the incident partial ray is a primary ray, the reflected main ray is a primary ray once again, and the scattered rays are secondary rays. During the reflection of secondary ray, only the reflected main ray is considered as the secondary ray.
