Patent number: 11736414Abstract: An apparatus comprising a socket insert that is arranged in a receptacle of the apparatus. The socket insert is connected to an operating medium connector. In the receptacle a data interface is covered by the socket insert and inaccessible from outside. To obtain access to the apparatus software or data, the socket insert can be replaced by a service insert that covers the operating medium output but contacts the data plug. The service insert allows communication with the apparatus control to input or output data and/or programs. The arrangement of the service interface covered by socket inserts provides an effective means for access control to the service interface. It impedes or avoids non-authorized access to the interface and damages for persons and material that otherwise could occur due to the missing disruptive discharge proof potential separation between the service interface and particularly the power section of the apparatus control.Type: GrantFiled: June 26, 2020Date of Patent: August 22, 2023Assignee: ERBE ELEKTROMEDIZIN GMBHInventors: Juergen Hiller, Marc Kegreiss

Publication number: 20230220776Abstract: A gas turbine has blades. A blade may have a leading edge; a trailing edge; a pressure side and a suction side, which extend between the leading edge and the trailing edge. The blade has, along the leading edge, a leading edge profile with profile portions, each of which, along its profile portion length, transitioning, proceeding from a depression, into an elevation via a first transition portion and back into a next depression via a second transition portion. An apex of the elevation of a profile portion is arranged in an asymmetric manner in relation to the profile portion length, in such a way that the first transition portion has a first transition length and the second transition portion has a second transition length. The first transition length and the second transition length are different lengths.Type: ApplicationFiled: January 4, 2023Publication date: July 13, 2023Inventor: Sven-Juergen HILLER

Patent number: 10751074Abstract: A surgical instrument having a long shaft comprises, in the shaft, a sealing element produced by primary shaping at the installation location. The sealing element is produced such that any actuating mechanisms are installed and held in place in the shaft and then a curable plastic material is injected into the shaft such that the material encloses the actuating element along a length that is greater than the inside diameter and smaller than its length.Type: GrantFiled: April 7, 2017Date of Patent: August 25, 2020Assignee: ERBE ELEKTROMEDIZIN GMBHInventors: Thomas Baur, Juergen Hiller, Viktoria Rydzewski

Patent number: 10512502Abstract: The invention relates to tissue scissors (10) with improved stability and improved handling that have two structurally and electrically different branches (11, 12). While the sliding surface (25) of the first branch (11) has a metal-ceramic hard material layer (30), such as, for example, titanium nitride, the second sliding surface (34) of the second branch (12) has an electrically non-conductive ceramic layer (33). The material mating produces great mechanical resistance to abrasion in the bearing (17) and on the cutting edges (28, 35). At least one of the branches, in particular branch (12), can have a cermet body (36) to improve the cooling of the cutting edge (35 (28)) and/or keep it sharp, to prevent heating of the branches (11, 12) during coagulation and sticking of the tissue.Type: GrantFiled: March 23, 2016Date of Patent: December 24, 2019Assignee: Erbe Elektromedizin GmbHInventor: Jürgen Hiller

Patent number: 9216052Abstract: An instrument suitable for minimal invasive surgery. The instrument can be introduced into a body, for example, through a trocar, and has two arms and a centrally guided knife for clamping vessels. The central guidance of the knife in at least one of the arms avoids disadvantages that could otherwise develop as a result of the off-center severing of coagulated tissue. Moreover, the clean central guidance of the knife results in lower wear on the knife. Thus, a better cut quality and a longer service life of the knife can be achieved.Type: GrantFiled: July 19, 2012Date of Patent: December 22, 2015Assignee: ERBE ELEKTROMEDIZIN GMBHInventors: Juergen Hiller, Thomas Baur, Ralf Kuehner, Viktoria Rydzewski

Publication number: 20110092970Abstract: An electrosurgical device for coagulating and/or cutting biological tissue that includes an instrument for application of high-frequency current, an activation switch, a high-frequency generator, and a safety unit. The instrument for application of the high-frequency current includes first and second branches having respective first and second jaw parts that are connected such that they are movable relative to one another. The safety unit interrupts the current supply to electrodes of the instrument when the jaw parts assume a position relative to one another that is not suitable for coagulation by means of the high-frequency current, e.g. when the jaw parts are open. Thus, erroneous operation of the device may be prevented.Type: ApplicationFiled: May 12, 2009Publication date: April 21, 2011Inventors: Tobias Alberstetter, Jürgen Hiller, Achim Brodbeck

Patent number: 6452355Abstract: The present invention is a control method and numerical control for the vibration-reduced acceleration of a movable machine element of a numerically controlled industrial processing machine, in which a path of movement of the machine or machine element is broken down into directly successive interpolatable movement sections In the interpolation, resultant acceleration profiles which lie in a range close to a critical natural frequency of the machine or machine element are carried out with a reduced acceleration. By this method, intervention is made only in critical ranges of the acceleration profile, uncritical ranges remain uninfluenced, as a result of which drastic time losses during positioning can be avoided.Type: GrantFiled: July 13, 2001Date of Patent: September 17, 2002Assignee: Siemens AktiengesellschaftInventors: Gerhard Forster, Juergen Hiller, Peter Kreusser
