摘要:
An adjustable assembly comprises a base (mount ring 1), an adjustable part (inner ring 3), a lever (tilting lever 5) and a drive (drive element 6). The lever (tilting lever 5) is connected to the base (mount ring 1) and to the adjustable part (inner ring 3) via two elastic solid pivoting joints (7, 8) oriented in parallel. One of the two solid pivoting joints (7) is divided into two pivoting joint parts (7a, 7b), which are arranged such that along their pivoting axis (9) they are offset sideways on either side of the second solid pivoting joint (8).

A method is disclosed of providing a message wait service to the users of an IP based telecommunication network (IPBN). For the invocation of a message wait service by a calling user, when said VOIP user is busy or not answering a call, or has forwarded all the calls unconditionally to a voice mail server, the method comprises the steps of: sending (201) from a proxy server (104), which takes care of redirecting the calls of said VOIP user (100), to a media gateway controller (102) of the IP based telecommunication network (IPBN), a message INVITE comprising a diversion header containing a diversion reason: user-busy, or no-answer; generating, in said media gateway controller (102), some procedure code for invocation of a message wait service provided by a voice mail server (151) in a time division multiplex network (PSTN), when said media gateway controller (102) receives said message INVITE; and then sending (202, 203) said procedure code, in an IAM message, towards said voice mail server (151) of said time division multiplex network (PSTN).
摘要:
A lithographic apparatus includes a projection system mounted on a reference frame, which in turn is mounted on a base which supports the apparatus. Vibrations and displacement errors in the base are filtered through two sets of isolation mounts operatively between the base and reference frame and between the reference frame and a projection frame of the projection system and therefore disturbance of the projection system is reduced.
