Granted: 2006-09-26
Abstract: A process and device are disclosed for carrying out in particular quantitative fluorescence immunity tests by means of evancacent field excitation, possibly on the basis of various known biochemical assays of systems generally composed of receptor-ligands. However, antibody-antigen systems are preferably evaluated. The invention should enable quantitative fluorescence immunity tests with various known biochemical assays to be carried out with a very simple device. For that purpose, a light source (7, 7) is used which emits rays of an almost monochromatic light having a wavelength which causes a marking substance bound to the antibody to become fluorescent. The light rays are directed at an angle .alpha. determined by a depth of penetration d previously determined for the evanescent field onto a boundary surface (20) between an optically transparent base plate (i) made of a material with a refraction index n1 higher than the refraction index n2 of the material above the boundary surface (20) and a cuvette-shaped sample-receiving area (2). The sample receiving area (2) is covered at the side opposite to the base plate (1) by a covering plate (3) and a detector (5) for sensing fluorescent light is arranged at the same side of the base plate (1) as the light source (7).

Title: Frequency lock indicator for fpll demodulated signal having a pilot
Inventor: SGRIGNOLI GARY J
IPC: H03L7/087
Filed: 1997-07-24
Granted: 2003-09-16
Abstract: A biphase stable FPLL includes a polarity determination circuit (36) that ascertains the lockup phase of the FPLL based upon the polarity of the pilot in the digital signal. A frequency lock indicator circuit (50-60) determines from the recovered pilot when frequency lock has occurred and the polarity determination circuit is responsive thereto for inverting the phase of the incoming signal (or alternatively, of the outgoing signal) as determined in order to supply an output signal of predetermined polarity. The frequency lock indicator consist of a zero crossings detector (50) and a latch (56) that is sampled for a time period. The zero crossings detector (50) is a delay (52) and an exclusive OR gate (54). An optional confidence counter (60) may be used with the latch (56) to determine when frequency lock has occurred to provide the lock indicator signal.

Title: A system for automatic generation of selective partial renderings of complex scenes
Inventor: KRATTLI JEAN-MARC
IPC: G06T15/00
Filed: 1999-03-30
Granted: 2007-09-25
Abstract: A computer-based system automates the production of so-called pass--images (or just "passes") from data defining 3-D scenes. For example, a beauty pass of a selected object the normal surface appearance without any background or other objects. A shadow pass shows only selected shadows and a highlight pass, only selected highlights. The passes allow pixel-processing to be done efficiently.  The processed passes can then be combined ("composited") to form the finished image. In the past, these passes were produced by editing a copy of the 3-D  scene for each pass and rendering the edited copy. The invention automates the production of passes by filtering the 3-D scene through pre-specified pass definitions that override properties of the 3-D scenes. The results of filtering are rendered (rendering largely comprises the process of ray-tracing) to form the passes. The system stores numerous pass definitions. Each time the 3-D scene is edited, the passes can be produced automatically from the pass definitions.  This automation of pass production also allows the passes to be used in the authoring environment by allowing a pass preview of the 3-D scene rendering. The automation of pass-production provides a tool that goes beyond merely reducing the labor involved in creating passes, it provides the author the option of invoking a new perspective, a different kind of immediate feedback, right in the authoring environment. This feedback enhances the author's ability to focus on specific features of a scene as the author edits the 3-D scene itself.

Granted: 2008-07-15
Abstract: The invention relates to a method and to a shearing and compacting press for the production of pressed parts, preferably packages (20) from waste material, especially scrap and sheet clippings. The material used is pre-compacted in a first compacting step. In a second compacting step, the material, which has been pre-compacted to the width of the package, is subjected to intermediate compacting until the height of the package (20) is reached. In a third compacting step, final compacting of the material to the final width or length of the package (20) is carried out. According to the invention, the material is pre-compacted with a continuos force and optionally sheared until the compressor (3.1) reaches its final position. The compressor (3.2) is securely adjusted and guided to its end position on a parallel plane. Subsequently, the compressor (3.3) is guided in a position in which the compressor (3.1) releases the opening of the package chamber (2.3) when the compressor (3.1) is driven back. Finally, the compressor (3.1, 3.2, 3.3) is subjected to a pressure that is lower than the maximum pressure available in the compressors (3.1, 3.2, 3.3) at the beginning of the working and return strokes. The compressor (3.1) is subjected to maximum pressure for shearing and/or the compressors (3.2, 3.3) are supplied with maximum pressure to end pressing. The invention is also characterized in that the pressing pressure for the compressors (3.1, 3.2, 3.3) is gradually controlled depending on the degree of compression or the corresponding length.
