Abstract: An optical assembly (100, 200, 300) for an EUV projection exposure apparatus (400) and/or an EUV mask metrology apparatus includes an optical component (101) configured to reflect EUV imaging light (102), a housing (104) that at least partly surrounds the optical component (101) and also encapsulates sections of an EUV beam pathway within the EUV projection exposure apparatus (400) or the EUV mask metrology apparatus, at least one particle trap (106, 206, 306) designed to reduce free particle contamination (105), especially by tin particles, within the housing (104) and having an opening (107, 207, 307) in the direction of the EUV beam pathway. The particle trap (106, 206, 306) is disposed in the housing (104), where the particle trap (106, 206, 306) has an interior and an inner surface (109) surrounding the interior and takes the form of a channel.

Abstract: A method for detecting misuse of a safety belt in a vehicle by a control unit (12) of the vehicle, comprising the following steps: a) recording vehicle parameters (P), b) supplying the vehicle parameters (P) to an artificial neural network (40); c) recording the at least one output value (A) of the artificial neural network (40), and d) detection of whether or not there is a misuse of the safety belt based on the output value (A). There is also a safety belt system (10) for a vehicle.

Abstract: A brake system for motor vehicles, which can be actuated in a “brake-by-wire” operating mode both by the vehicle driver and independently of the vehicle driver. In the “brake-by-wire” operating mode the system can be operated in at least one fallback operating mode, with a brake master cylinder, actuated by a brake pedal, having a housing and two pistons, which delimit two pressure chambers, are assigned to brake circuits with wheel brakes, a pressure medium reservoir, one electrically actuable inlet valve per wheel brake for setting wheel-individual brake pressures, a first electrically controllable pressure provision device for loading the wheel brakes with pressure, and a second electrically controllable pressure provision device with at least one vacuum connector and a pressure connector, the vacuum connector is connected to the pressure medium reservoir. The pressure connector is connected to at least one wheel brake without a valve being connected in between.

Abstract: A method of transmitting data between a first and a second device (2, 3) by way of a power supply line between the first and the second device (2, 3). The power supply and the data transmission take place alternately in a power supply time window (21) and in a data transmission time window (22). As a result of this measure, a separate data transmission line is not be necessary.
