Patent number: 8493143Abstract: Disclosed is a predistortion linearizer for power amplifiers using a bridge topology, which has the advantages that an equalizer stage is disposed in each of the linear and nonlinear branches. This equalizer stage is used to adjust the frequency response of the complex expansion of the bridge. The equalizers introduce variable transmission functions in the linear and nonlinear bridge branches, so that the linearizer compensates for the individual nonlinear frequency response of a power amplifier, which varies within a manufacturing lot.Type: GrantFiled: September 10, 2009Date of Patent: July 23, 2013Assignee: Tesat-Spacecom GmbH & Co. KGInventors: Abdel-Messiah Khilia, Detlef Leucht, Walter Gross, Michael Jutzi, Hartmut Schreiber

Patent number: 7357445Abstract: An adaptive crash structure of a vehicle body or chassis of a motor vehicle includes a first metal casting and a second metal casting. A deformation element in the form of a metal casting for absorbing energy interconnects and forms with the first and second metal castings a single piece construction through a casting process. The deformation element is comprised of a plurality of funnel-shaped wedge bodies which are disposed in succession, with neighboring wedge bodies being connected through intervention of a predetermined breaking web. Each wedge body is defined by a diameter, wherein the diameters of the wedge bodies are sized to allow the wedge bodies to move telescopically into one another when a limit stress is reached and the predetermined breaking webs rupture so as to effect a tight intergrip of the telescoping wedge bodies in a self-locking manner.Type: GrantFiled: August 28, 2006Date of Patent: April 15, 2008Assignee: Benteler Automobiltechnik GmbHInventors: Walter Gross, Jens Stolle, Hans-Jürgen Neumann, Wolfgang Streubel

Patent number: 6762430Abstract: An imaging plate guide formed in different configurations corresponding to the various intraoral dental plate sizes, which in turn correspond to the dental intraoral film sizes commonly referred to as sizes 0 through 4, the imaging plate guides dedicated to intraoral imaging providing for guides for each plate size so that a desired array of feed width guides can be positioned on the scanner for scanning the intraoral plates and which scan extraoral imaging plates as well. The embodiment of the imaging plate guides provides not only for interchangeability with respect to the intraoral plate size, but also allows for the feeding of extraoral imaging plates without the need to remove the intraoral plate guides. The size 4 is not specifically described, but is analogous to the other sizes as would be obvious to one skilled in the art.Type: GrantFiled: December 5, 2002Date of Patent: July 13, 2004Assignee: Air Techniques, Inc.Inventors: Edgar Alzner, Stephen Zamprelli, Tom Lloyd, Walter Gross
