Abstract: An energy storage element includes a sealed housing and an electrode-separator assembly disposed therein. The housing includes a metallic cup-shaped housing part having a housing bottom, a circumferential side wall, and a terminal opening, and a lid assembly closing the terminal opening of the cup-shaped housing part. One edge of an anode current collector or of a cathode current collector is electrically connected to the housing bottom and another edge is electrically connected to a contact sheet metal member which is directly seated on this edge. The lid assembly includes a metallic cover plate and a terminal pole which is guided through an aperture in the cover plate and is electrically insulated from the cover plate. The terminal pole is seated directly on the contact sheet metal member and is connected thereto by welding. Furthermore, the terminal pole is electrically insulated from the cover plate by a cured potting compound.

The first focusing optical element includes a first region having a first optical power, and a second region having a second optical power different from the first optical power. The light guiding layer is configured to: i) receive light from the light projector, ii) direct at least a first portion of the light to a user’s eye through the first region to present a first virtual image to the user at a first focal distance, and iii) direct at least a second portion of the light to the user’s eye through the second region to present a second virtual image to the user at a second focal distance.

Abstract: A method determines damage which occurs on the vehicle in the event of an accident between a vehicle and a collision partner. The method analyzes information about an acceleration profile of the vehicle provided by an acceleration sensor. The analysis is performed as to whether the acceleration profile exhibits at least one sudden change or jump. The method generates an output signal which includes an item of information about damage which has occurred on the vehicle in the event of the accident, based on a number of changes or jumps which are identified during the analysis of the acceleration profile.

Abstract: A brake dust particle filter for an assembly with a brake disc is provided with a ring section-shaped housing that at least partially surrounds the brake disc in a mounted state. The housing has a housing interior. The housing is made of a metal material. The housing interior has a lowermost point and has at the lowermost point an axially embodied drainage cutout for drainage of a fluid out of the housing interior. The housing has an outwardly positioned, mostly axially expanding guide arranged at the drainage cutout for guiding the fluid. An assembly with a brake disc and a brake caliper arranged at the brake disc is provided with such a brake dust particle filter that is arranged at least partially in a bottom region of the brake disc.
