Patent number: 8221406Abstract: A high frequency current application apparatus for thermal sclerosing of body tissue, comprising a high frequency generator connected to at least two electrodes, one of which is to be introduced into body tissue. The apparatus includes a measuring and calculating device adapted to ascertain impedance (or ohmic resistance) between the two electrodes between which a respective therapeutic high frequency current flows. A control device is connected to the measuring and calculating device for varying the output power. During high frequency current application the measuring and calculating device forms the first derivative with respect of time of the impedance. The control device reduces output power when that derivative exceeds a positive threshold characteristic of a threat of tissue desiccation and restores output power to the original power when the first derivative exceeds in positive values a negative threshold characteristic of adequate rehydration of body tissue.Type: GrantFiled: August 19, 2005Date of Patent: July 17, 2012Assignee: Celon AG Medical InstrumentsInventors: Kai Desinger, Thomas Stein, André Roggan, Thomas Prezewowsky

Patent number: 8216219Abstract: An electrode array is used for the thermal schlerosing of body tissue. The electrode array has at least three active electrodes that, during use, are placed in electrical-conducting connection with body tissue. A high frequency generator is electrically connected for selective application of current to the active electrodes for producing a high frequency voltage. A measuring device measures impedance of the tissue between the active electrodes. In addition, a selector device selects a sub-array including at least two active electrodes from the electrode array, the selecting being effected on the basis of the measured impedance. Further, a control device is configured such that a high frequency voltage is respectively applied between the active electrodes of the selected sub-array in such a way that a high frequency current flows between the selected active electrodes through the body tissue.Type: GrantFiled: May 23, 2003Date of Patent: July 10, 2012Assignee: Celon AGInventors: Kai Desinger, Thomas Stein, Andre Roggan, Thomas Prezewowsky

Publication number: 20110232024Abstract: A vacuum cleaner has a lid that selectively opens or closes a filter bag compartment. A secondary motor protection filter is removably mounted in the lid by a frame of an elastic material that simultaneously seals the secondary filter element to the lid and seals the lid onto the bag compartment. An air passage flows between the secondary filter and the lid through a duct to the suction motor compartment. A perimeter groove in the lid receives a spline of the elastic frame of the filter element in a removable manner, while the opposite surface of the frame forms the seal surface relative to a housing rim around the bag compartment.Type: ApplicationFiled: March 2, 2011Publication date: September 29, 2011Applicant: Stein & Co.

Publication number: 20110232687Abstract: A vacuum cleaner includes a variable speed suction motor and an illuminatable motor speed indicator having plural lights arranged in a circular pattern or annular ring pattern, for example around a motor speed control switch. A control unit includes an indicator controller and a motor controller that respectively control the illuminatable indicator and the motor, based on inputs from the motor speed control switch and optionally at least one sensor that senses operating conditions of the vacuum cleaner. The lights are successively activated and deactivated to create a visible light spot that appears to rotate around the circular or annular ring pattern at a light rotation rate related to and indicative of the motor rotation speed.

Patent number: 7911598Abstract: Components (30) in the interior of an EUV lithography device for extreme ultraviolet and soft X-ray wavelength range are cleaned by igniting a plasma, adjacent to the component (30) to be cleaned, using electrodes (29), wherein the electrodes (29) are adapted to the form of the component (30) to be cleaned. The residual gas atmosphere is measured spectroscopically on the basis of the plasma. An emission spectrum is preferably recorded in order to monitor the degree of cleaning. An optical fiber cable (31) with a coupling-in optical unit (32) is advantageously used for this purpose. Moreover, in order to monitor the contamination in the gas phase within the vacuum chambers during the operation of an EUV lithography device, it is proposed to provide modules configured to initiate a gas discharge and to detect radiation emitted on account of the gas discharge. The contamination in the gas phase can be deduced from the analysis of the measured spectrum.Type: GrantFiled: September 8, 2009Date of Patent: March 22, 2011Assignee: Carl Zeiss Smt AGInventors: Dieter Kraus, Dirk Heinrich Ehm, Thomas Stein, Harald Woelfle, Stefan-Wolfgang Schmidt

Publication number: 20100288302Abstract: The invention is directed to a method for at least partially removing a contamination layer (15) from an optical surface (14a) of an EUV-reflective optical element (14) by bringing a cleaning gas into contact with the contamination layer. In the method, a jet (20) of cleaning gas is directed to the contamination layer (15) for removing material from the contamination layer (15). The contamination layer (15) is monitored for generating a signal indicative of the thickness of the contamination layer (15) and the jet (20) of cleaning gas is controlled by moving the jet (20) of cleaning gas relative to the optical surface (14a) using this signal as a feedback signal. A cleaning arrangement (19 to 24) for carrying out the method is also disclosed. The invention also relates to a method for generating a jet (20) of cleaning gas and to a corresponding cleaning gas generation arrangement.Type: ApplicationFiled: May 6, 2010Publication date: November 18, 2010Inventors: Dirk Heinrich Ehm, Arnold Storm, Johannes Hubertus Josephina Moors, Bastiaan Theodoor Wolschrijn, Thomas Stein, Edwin te Sligte
