Title: Device for particles detection in a pipeline
Inventor: JANSSON LENNART CARL ERIK
IPC: A62C3/00
Filed: 1994-10-03
Granted: 2005-11-29
Abstract: The invention pertains to a detector arrangement (1) in- cluded in a preventive safety sys- tem that can be used within a process in which loosely-formed process material is produced in a first unit (2) and transported (3) to a receiving, second unit (2), wherein the treatment to which the material is subjected in said first unit is liable to produce one or more discrete particles which have a temperature sufficiently high to initiate fire and/or explo- sion within at least the second part or unit (2). The necessary transportation of the loose ma- terial between the first unit (1) and the second unit (2) is ef- fected along a path which in- cludes a stabilizing zone (7), a high-temperature particle indicat- ing zone (8), and an extinguish- ing zone (9), wherein the indi- cating zone includes one or more particle sensors (10). The sensors coact with an indicating and activating unit (12) such that indication by th e sensors of the presence of a high-temperature particle in said indicating and activating unit will activate a device which is associated wi th the extinguishing zone and which functions to deliver an extin- guishing agent and/or to remove particles (15). The sensing lobes of two sen sor units (105, 107) cover a cross section of the transp ortation path. The indicating and activating unit(12) is adapted to evaluate the sens ed intensity from each of said sensor units (105, 107) and to coordinate received intensity-dependent signals so as to calculate and estab lish on the basis thereof the liability of the particle to initiate fire and/or explosion.

Title: Control symbol and data symbol guard intervals with different time lengths in cofdm transmission frames
Inventor: WECK CHRISTFRIED
IPC: H04H20/67
Filed: 1995-07-20
Granted: 2001-12-25
Abstract: In order to prevent wanted signal capacity from being reduced during OFDM  modulation of digital coded data, control symbol protecting intervals in the frame head of each OFDM transmission frame are larger than data symbol protecting intervals in wanted data areas of each OFDM transmission frame.

Abstract: The present invention is a method for ranking the affinity of each of a multiplicity of different molecules for a target molecule which is capable of denaturing due to a thermal change. The method comprises contacting the target molecule with one molecule of the multiplicity of different molecules in each of a multiplicity of containers, simultaneously heating the multiplicity of containers, measuring in each of the containers a physical change associated with the thermal denaturation of the target molecule resulting from the heating in each of the containers, generating a thermal denaturation curve for the target molecule as a function of temperature for each of the containers and determining a midpoint temperature (T m) therefrom, comparing the T m of each of the thermal denaturation curves with the T m of a thermal denaturation curve obtained for the target molecule in the absence of any of the molecules in the multiplicity of different molecules, and ranking the affinities of the multiplicity of different molecules according to the change in T m of each of the thermal denaturation curves.  The present invention also provides an assay apparatus for that includes a temperature adjusting means for simultaneously heating a plurality of samples, and a receiving means for receiving spectral emission from the samples while the samples are being heated. In further aspects of the invention, the receiving means can be configured to receive fluorescent emission, ultraviolet light, and visible light. The receiving means can be configured to receive spectral emission from the samples in a variety of ways, e.g., one sample at a time, simultaneously from more than one sample, or simultaneously from all of the samples. The temperature adjusting means can be configured with a temperature controller for changing temperature in accordance with a pre-determined profile.

Abstract: During an encoding operation, one of the R, G, B components of a pixel in the image are eliminated. In a first pixel, the B component is eliminated, and then in a second pixel which is to the right of the first pixel, the R component is eliminated. Further, in a third pixel to the right of the second pixel, the G component is eliminated. In the same manner, R, G, B components are thereafter eliminated in a three-pixel cycle. During a decoding operation, an estimated value of a color component that was eliminated in the pixel is determined on the basis of the color components of adjacent pixels. A correction value is then computed based on the color components of the adjacent pixels. As a result, the estimated value of the eliminated color component is adjusted using the computed correction value to produce a good quality image.
