摘要:
A projection exposure system (10) for microlithography which includes: a mask holding device (14) holding a mask (18) with mask structures (20) disposed on the mask, a substrate holding device (36) holding a substrate (30), projection optics (26) imaging the mask structures (20) onto the substrate (30) during an exposure process, and a measurement structure (48) disposed in a defined position with respect to a reference element (16) of the projection exposure system (10), which defined position is mechanically uncoupled from the position of the mask holding device (14). The projection exposure system (10) also includes a detector (52) arranged to record an image of the measurement structure (48) imaged by the projection optics (26). The projection exposure system (10) is configured such that during operation of the projection exposure system (10) the imaging of the mask structures (20) and the imaging of the measurement structure (48) take place at the same time by the projection optics (26. An evaluation device (54) is configured to establish a lateral position of the image of the measurement structure (48) in the area of the detector (52) during the exposure process.

摘要:
A process for providing information related to an individual or an animal in a portable display and storage device that allows other individuals to access the personal and medical information quickly. The process includes entering the information in formatted screens of data in a computer, transferring the formatted screens of data to the portable display and storage device, storing the formatted screens of data in the portable display and storage device, and displaying the formatted screens of data in the portable display and storage device. In some embodiments, the formatted screens of data in the display and storage device are transferred to a computer, modified, and transferred back to the display and storage device.
摘要:
A wind instrument such as a recorder or a flute is disclosed. The wind instrument may include a body fabricated from a clear or translucent light-transmitting material, with or without color. The body includes a compartment and a light source retained within the compartment. The light source may direct light along and through the body of the wind instrument. The light source may include multiple colored LEDs or other light-emitting devices.
摘要:
The invention relates to an optical bench that has a base plate and can be permanently connected to an associated component. A receiving element for other optical elements that is arranged in such a way in relation to the base plate with connecting elements that it is deformable in its entirety in relation to said base plate, is allocated to the same.
摘要:
A method of bridging a gap in an external electrical power supply line without stalling using an electrically powered rail propulsion vehicle includes using an electrically powered rail propulsion vehicle to propel a consist, the electrically powered rail propulsion vehicle configured to run as an emission-free pure electric unit from the external electrical power supply line; determining if a gap in the external electrical power supply line condition occurs; and supplying electric power from one or more ultracapacitor packs to run the electrically powered rail propulsion vehicle if a gap condition is determined to occur.
