摘要:
In general, in one aspect, the invention features a catadioptric projection objective having a plurality of optical elements arranged along an optical axis to image a pattern arranged in an object surface of the projection objective onto an image surface of the projection objective. The optical elements include a concave mirror; a first deflecting mirror tilted relative to the optical axis by a first tilt angle t1 about a first tilt axis to deflect light from the object surface towards the concave mirror or to deflect light from the concave mirror towards the image surface; and a second deflecting mirror tilted relative to the optical axis by a second tilt angle t2 about a second tilt axis. The first deflecting mirror has a first reflective coating with reflectivity Rs1(α1) for s-polarized light and a reflectivity Rp1(α1) for p-polarized light incident on the first deflecting mirror at first angles of incidence α1 from a first range of angles of incidence according to (t1−Δα1)≦α1≦(t1+Δα1). The second deflecting mirror has a second reflective coating with a reflectivity Rs2(α2) for s-polarized light and a reflectivity Rp2(α2) for p-polarized light incident on the second deflecting mirror at second angles of incidence α2 from a second range of angles of incidence according to (t2−Δα2)≦α2≦(t2+Δα2). A first reflectivity sum, RsPE, for s-polarized light of polar edge rays accumulated upon reflection on the first and second deflecting mirrors is substantially equal to a second reflectivity sum, RpE for p-polarized light of equatorial edge rays accumulated upon reflection on the first and second deflecting mirrors.

An improved metal mesh with lights and an arrangement of such a mesh on a building are proposed. A light carrier receptacle is integrated in a mesh and thereby allow a light carrier to be removed from the mesh and reinserted without disintegrating the light carrier receptacle. Alternatively, a light carrier receptacle is attached to a mesh or other hanging, to which the light carrier is then attached. Clips can be preferably used.

The disclosure relates to a method of manufacturing a polarization-modulating optical element, wherein the element causes, for light passing through the element and due to stress-induced birefringence, a distribution of retardation between orthogonal states of polarization, the method comprising joining a first component and a second component, wherein a non-plane surface of the first component being provided with a defined height profile is joined with a plane surface of the second component, whereby a mechanical stress causing the stress-induced birefringence is produced in the such formed polarization-modulating optical element.

A method and apparatus for operating an electronic program guide on a portable mobile communications device is presented. The portable mobile communications device is part of a larger network that is communicable with a mobile radio access network (MRAN) and capable of receiving broadcasts from a mobile television service provider. The portable mobile communications device displays a list of programs available and accepts input that selects one of the programs. This causes a display of the list of options that can be applied to the selected program. The portable mobile communications device then accepts input and performs the selected option for the selected program. The list of options includes an option to record the selected program locally, remotely, or on a home personal video recorder (PVR). In addition, list of options that can be applied to the selected program includes an option to set a reminder for the selected program.

The application is directed to methods, systems, procedures, networks and storage apparatus used to conduct conversions of data using remote conversion servers. In one embodiment of the present invention, recent query results may be stored and then used to solve subsequent conversions rather than querying a remote conversion server when the same conversion was previously completed. A counter may be referenced to determine if too much time has passed since the original query was stored in the buffer and, if too much time has passed, the buffer may be cleared and the remote conversion server may be queried to convert the pending data. The resulting conversion may be stored for subsequent use.
摘要:
A gas sensor, comprises a substrate, a sensor unit including a functional layer and an electrode structure, and an electric heating and/or temperature measuring arrangement. An electrically conductive shielding structure is provided between the sensor unit and the electric heating arrangement in order to shield the measurement process at the sensor unit from interferences owing to the heating process, thereby reducing or preventing the effects of electrical fields caused by voltages applied to the heating arrangement from altering or disrupting the measurement process.

A process and apparatus for selective detection of NO in fluid media, particularly exhaust gases of internal-combustion engines. This process comprises the steps of positioning a nitrosonium-conducting solid electrolyte between two porous electrodes, acting upon one of the two electrodes with the NO-containing fluid medium, and measuring a voltage difference between the two electrodes as an indication of the NO-concentration in the NO-containing fluid medium.
