Abstract: 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.

Abstract: An interspinous process spacer and method of implanting same is provided for maintaining separation between adjacent spinous processes of adjacent vertebrae. The spacer has two lateral portions and a medial portion therebetween, the medial portion adapted to reside between the adjacent superior and inferior spinous processes in the deployed configuration and the lateral portions each comprise a superior lateral portion and an inferior lateral portion adapted to reside on the lateral side of the respective superior and inferior spinous process in the deployed configuration to maintain positioning of the interspinous process spacer between the two adjacent vertebrae. The lateral portions each comprise an expandable lateral member.

Abstract: 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.

Abstract: These and other objects of the present invention are achieved by an apparatus and process for evaluating an image-wise exposed storage film positioned about a cylindrically-shaped member and linearly passed a cylindrically-shaped slot for interrogation by a light beam wherein a processing assembly is co-axially disposed within a processing chamber formed by the cylindrically-shaped member and wherein the processing assembly includes a plate member disposed for rotation in a plane perpendicular to the axis of the processing chamber and having a pentaprism and a fluorescence light sensor positioned proximate a contact point of the interrogating light beam with the storage film and further including converting electronics for the thus generated fluorescence light wherein after interrogation, the storage film is immediately restored in the same apparatus for subsequent reuse.

Abstract: 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.
