Title: Electrical property enhanced tomography (epet) apparatus and method
Inventor: GREGORY WILLIAM D
IPC: G01N27/24
Filed: 1998-09-10
Abstract: Enhanced information on the electrical properties of the subregion (208-216) of a sample (204) is generated by an enhanced tomography (EPET) apparatus (600) connected to a tomograph device, wherein the EPET apparatus (600) holds a voltage constant, and measures the electrical current of the sample (204) inserted within the EPET  apparatus (600). A matching medium (602) is applied to the sample (204) inserted within the apparatus (600). A matching medium (602) is applied to the sample (204) such that when the sample (204) is placed within an electromagnetic field generated by the EPET  apparatus (600), the matching medium (602) contacts the segmented sensor plates (606) of the EPET apparatus (600), and allows the detection of the net total charges Q on the surface (202) of the sample (204). The EPET apparatus (600) uses these net total charges Q in the calculation of additional information on the electrical properties of the sample (204) by using the scale factor method or the iteractive correction method.

Filed: 1998-10-09
Abstract: A multi-spectral imaging system (10) and method produces a vegetation image (78) for analysis of crop characteristics, such as nitrogen levels, from an area (12) having vegetation (14) and a non-vegetation (14) background. A light sensing unit (18) deters light reflected at multiply wavelengths. The image is segmented into images (70, 72, 74) at different wavelengths such as at the red, green, and near infrared wavelengths. The images are combined into a multi-spectral image (76) and segmented into a vegetation image by eliminating all non-vegetation images by using the images at two wavelengths. The vegetation image (78) is analyzed for nitrogen levels by calculating reflectance values at the green wavelength. The images may be stored for further analysis of crop characteristics.

Title: Method for securing a system protected by key hierarchy
Inventor: SCHWENK JORG
IPC: H04H20/00
Filed: 1997-12-18
Abstract: The invention relates to a method for securing at least one system protected by a predetermined hierarchy of cryptographic keys, more particularly a Pay-TV system, against unauthorized users. Current key hierarchy systems do not enable detection of unreliable clients who make copies of a group key transmitted by a system provider and pass them on to other persons. According to the invention, this is solved by detecting at least one individual cryptographic key assigned to an unreliable user by forming the intersection of at least two predetermined subsets formed at different times and belonging to the same hierarchy.

IPC: C25C7/02
Filed: 1999-09-23
Abstract: This invention concerns starting cathodes of copper sheet for copper electrolysis and a method of producing the starting cathodes.     Starting from the disadvantages of the known state of the art, the object of this invention was to create starting cathodes which prevent a memory effect during copper electrolysis, with which a high production output of electrolytic copper can be achieved and which can also be manufactured from directly shaped copper sheeting material in the form of a coil.     Furthermore, a suitable method of producing starting cathodes is to be created which is also suitable in particular for processing copper sheet produced by conventional methods.     The proposed starting cathodes are made of milled copper sheet with a thickness of 0.3 to 1.2 mm, which is soft annealed after milling and has a strength of 210 to 240 N/mm2. The copper sheet is cut to the length and width determined by the dimensions of the electrolysis bath and has a flat, fat-free, burless surface. Ear strips of copper sheet with a thickness of 0.3 to 0.6 mm are mounted on the suspension side.

Abstract: A cellular terminal adapted to connect a telephone communication device to a cellular telephone network, which terminal includes a transmitter periodically sending a registration signal to the network and a receiver receiving acknowledgement signals sent by the cellular telephone network in response to the registration signals. A counter records the number of consecutive acknowledgement signals not timely received by the cellular terminal (incrementally increasing each time a signal is not timely received, and resetting to zero when a signal is received), with corrective action being initiated to reestablish proper connection between the cellular terminal and the cellular telephone network when the number recorded by the counter exceeds a selected threshold number. Continuous verified interaction of the cellular terminal and cellular telephone network is provided by (1) sending periodic registration messages from the cellular terminal to the cellular telepnone network, (2) sending acknowledgement signals from the network to the terminal in response to registration messages, (3) counting the number of consecutive acknowledgement signals not timely received by the cellular terminal, and (4) initiating correction of a failure of interaction of the cellular terminal and cellular telephone network when the counted number of consecutive acknowledgement signals not timely received reaches a selected threshold number. Corrective action may be initiated by signalling an error condition to a user of the fixed cellular terminal and/or by generating an instruction signal causing the fixed cellular terminal to reset.

Filed: 2001-02-13
Abstract: This invention provides a method for indicating a high or low risk of developing pathology at specific sites along epithelial tissues, according to a model of carcinogenesis and measurements of activated enterocytes. The method determines the presence and the intensity of a "promoting environment," a region of intestinal epithelial cells which are biochemically programmed as activated enterocytes to develop pathology sus as neoplasia or such as cancer in response to certain signals. The model predicts that neoplasia can develop only in such an environment when the promoting influence is sufficiently intense. In which case to provide the ability to identify pathologic tissues If cancer is determined to be present, this method enables one to assess the stage of cancer, which can be used to monitor the effectiveness of therapeutic regimes during the course of treatment for a patient. The method can also be used in the field of cancer research to develop understanding of the etiology of the disease in addition to new treatments for cancer therapy. It also provides an opportunity to use the method as a tool to investigate pathologic development such as pre-cancerous states in animal and cell culture models of diseases.
