Patent number: 8717531Abstract: A mirror serves for guiding a radiation bundle. The mirror has a basic body and a coating of a reflective surface of the basic body, the coating increasing the reflectivity of the mirror. A heat dissipating device serves for dissipating heat deposited in the coating. The heat dissipating device has at least one Peltier element. The coating is applied directly on the Peltier element. A temperature setting apparatus has at least one temperature sensor for a temperature of the reflective surface. A regulating device of the Temperature setting apparatus can be connected to the at least one Peltier element and is signal-connected to the at least one temperature sensor. The result is a mirror in which a heat dissipating capacity of the heat dissipating device is improved.Type: GrantFiled: February 18, 2010Date of Patent: May 6, 2014Assignee: Carl Zeiss SMT GmbHInventors: Severin Waldis, Florian Bach, Daniel Benz, Armin Werber, Wilfried Noell, Dirk Heinrich Ehm, Stefan Wiesner, Dieter Kraus

Patent number: 8494250Abstract: Spatial relationships are conveyed in three-dimensional ultrasound imaging. To transition a volume rendering from one view to another view, the transition is animated, showing rotation. For example, the user examines one diagnostic view, but decides to examine another diagnostic view. Upon selection of the other diagnostic view, the volume rendered image appears to rotate. The rotation from one view to another shows the spatial relationship between the views. The user may then examine the static volume rendering at the desired view with an appreciation of the relationship with the previously examined static view.Type: GrantFiled: January 9, 2009Date of Patent: July 23, 2013Assignee: Siemens Medical Solutions USA, Inc.Inventors: Bruce A. McDermott, Mervin Mencias Smith-Casem, Patric Ljung, Stefan Wiesner

Publication number: 20120086925Abstract: A method for preventing contaminating gaseous substances (18) from passing through an opening (17b) in a housing (4a) of an EUV lithography apparatus (1), wherein at least one optical element for guiding EUV radiation (6) is arranged in the housing (4a). The method involves: generating at least one gas flow (21a, 21b) which deflects the contaminating substances (18, 18?), and in particular is directed counter to the flow direction (Z) thereof, in the region of the opening (17b). The gas flow (21a, 21b) and the EUV radiation (6) are generated in pulsed fashion and the pulse rate of the gas flow (21a, 21b) is defined in a manner dependent on the pulse rate of the contaminating substances (18, 18?) released under the action of the pulsed EUV radiation (6), wherein both pulse rates are preferably equal in magnitude, and wherein, in the region of the opening (17b), the gas pulses temporally overlap the pulses of the contaminating substances (18, 18?).Type: ApplicationFiled: October 6, 2011Publication date: April 12, 2012Applicant: CARL ZEISS SMT GMBHInventors: Dieter KRAUS, Dirk Heinrich EHM, Stefan-Wolfgang SCHMIDT, Stefan WIESNER, Almut CZAP, Stefan KOEHLER, Hin Yiu Anthony CHUNG
