Patent number: 9373455Abstract: A hydromechanical stored-energy spring mechanism is provided for operating at least one switching contact of a circuit breaker, for example, in a high-voltage switching system. The hydromechanical stored-energy spring mechanism includes a hydraulically operated close-open (CO) delay circuit configured to delay triggering of a switching process of the circuit breaker, and an electromechanical actuator provided in place of a hydraulic operation of the CO delay circuit. The electromechanical actuator generates a mechanical time delay or acceleration over an extended temperature range.Type: GrantFiled: February 3, 2012Date of Patent: June 21, 2016Assignee: ABB TECHNOLOGY AGInventors: Jörg Knospe, Henrik Lohrberg, Joachim Eggers, Franz-Josef Körber, Thomas Brenneis

Publication number: 20100089738Abstract: A hydromechanical stored-energy spring mechanism is provided for acting upon high-voltage switches. The mechanism includes a drive cylinder having a piston guided therein. The mechanism also includes a piston rod which is articulated on the piston and which penetrates centrally through a cylinder block provided with a reception bore as a guide for a damping ring. The damping ring is arranged in the reception bore of the cylinder block. The outside of the damping ring bears on the cylinder block housing, and the outside of the damping ring has a protuberance.Type: ApplicationFiled: October 7, 2009Publication date: April 15, 2010Applicant: ABB TECHNOLOGY AGInventors: Joachim Eggers, Claus Sticker

Patent number: 7652221Abstract: The disclosure relates to a contact drive arrangement for the movement of at least one contact in high-voltage switchgear systems having a contact drive and having an auxiliary switch, which has at least two auxiliary contacts. The contact drive works together with the at least one contact and with a first auxiliary contact. Furthermore, a delay drive is connected functionally in parallel with the contact drive, and the delay drive works together with a second auxiliary contact. The first and second auxiliary contact are electrically connected in series. In addition, the delay drive has a damping element, and by means of the damping element the time for a switching operation is extended in comparison with the time for a switching operation with the contact drive.Type: GrantFiled: December 5, 2007Date of Patent: January 26, 2010Assignee: ABB Technology AGInventors: Henrik Lohrberg, Joachim Eggers

Patent number: 7577267Abstract: For a hearing aid, the information for the hearing aid wearer relating to the state of charge of the power source (4, 4?) or the remaining life of the hearing aid with the relevant power source (4, 4?) is to be improved. To this end means are provided for operating the hearing aid by which the state of charge or remaining life can be interrogated at any time, with the information about the state of charge or remaining life being provided to the hearing aid wearer by emitting an acoustic signal indicating the state of charge or remaining life. The hearing aid wearer can thus be informed conveniently and discretely at any time about the state of charge or the remaining life.Type: GrantFiled: May 19, 2005Date of Patent: August 18, 2009Assignee: Siemens Audiologische Technik gmbHInventors: Roland Barthel, Bernd Beimel, Joachim Eggers, Matthias Fröhlich

Patent number: 7574012Abstract: Concurrent signal paths going pass a hearing aid bring about interferences in the auditory canal. These interferences are compensated by estimating an interfering signal from the input signal disturbed by interference from a microphone and applying to the interfering signal a transfer function, with which the concurrent acoustic signal path is simulated, thereby forming an interfering output signal, and combining a usable output signal from a signal-processing device with the interfering output signal. In this way, a noise suppression by directional microphone switching configurations can be made possible when concurrent signal paths do not make such directional microphone switching possible by conventional approaches.Type: GrantFiled: December 10, 2004Date of Patent: August 11, 2009Assignee: Siemens Audiologische Technik GmbHInventors: Joachim Eggers, Volkmar Hamacher

Patent number: 7254245Abstract: The microphones used in hearing devices normally possess different characteristic lines that are to be adapted to one another. For this purpose, the amplitude of an output signal of a first microphone and the amplitude of an output signal of a second microphone are measured. The output signal of the first microphone is subsequently filtered dependent on both measured amplitudes, such that the difference between the two output signals is reduced. One of the two microphones hereby serves as a reference, and an absolute normalization can be foregone.Type: GrantFiled: March 11, 2004Date of Patent: August 7, 2007Assignee: Siemens Audiologische Technik GmbHInventors: Georg-Erwin Arndt, Joachim Eggers, Thomas Hanses, Torsten Niederdränk, Hartmut Ritter, Gunter Sauer

Publication number: 20050105760Abstract: Disclosed are a method and arrangement for embedding data (dn) in a host signal (xn) using dithered quantization index modulation (71), and extracting said data from the watermarked signal. A problem of this embedding scheme (71) is that the amplitude of the watermarked signal (sn) may have been scaled (72) unintentionally (by a communication channel) or intentionally (by a hacker). This causes the quantization step size (?r) of the received signal (rn) to be unknown to the extractor (73) which is essential for reliable data extraction. The invention provides making a histogram (74) of those signal samples that have substantially the same amount of dither, and analyzing said histogram to derive an estimation of the step size (?r) therefrom. In a preferred embodiment, a pilot sequence of predetermined data symbols (dpilot) is embedded (76) in selected (S) samples of the host signal.Type: ApplicationFiled: November 20, 2002Publication date: May 19, 2005Inventors: Joachim Eggers, Robert Baeuml
