Relief object image generator

A device for imaging a relief object without illuminating a platen is disclosed. The device includes a single electrode electroluminescent device, which may be inorganic or organic, and a current source. The current source is coupled to the single electrode of the electroluminescent device and to the relief object to be imaged. The valleys and ridges of the relief object couple current to the electroluminescent device at different magnitudes which causes the electroluminescent device to generate light at different intensities that correspond to the ridges and valleys of the relief object. The generated light forms an image of the relief object which may be focused by optical elements onto a sensor array for capture and image processing. In another embodiment of the invention, a one-to-one sensor array is located proximate the electroluminescent device to capture the image. In an embodiment of the invention which insulates the relief object from current, the electroluminescent device is covered with a variable resistance layer and the variable resistance layer is covered with a flexible electrode. One lead from the current source is coupled to the flexible electrode and another lead is coupled to the single electrode. When a relief object is brought in contact with the flexible electrode, a localized pressures generated by the ridges of the relief object form conductive paths through the variable resistance layer which are lower in electrical resistance than those formed by pressure in the areas adjacent the valleys of the relief object. The different magnitudes of current delivered through the conductive paths to the electroluminescent device cause the electroluminescent device to generate an image of the relief object without exposing the relief object to electrical current.

Boron coated straw neutron detector

ActiveUS20050258373A1Improve scatter angle measurementHigh levelImpression capsElectric discharge tubesCharge divisionWavelength range
A neutron detector technology based on 10B thin film conversion of neutrons and detection of neutron capture reaction products in a counter gas within a thin straw tube detector body is described. This neutron detector is based on gas-filled thin wall straw tubes, modified for the conversion of neutrons in a very thin coating, or layer, of 10B, applied for example as a sputter-coated film of 10B4C, that lines the interior, or inside of the straw tube surface; and the subsequent detection of the neutron reaction products in the counter gas. One embodiment of this invention employs a closely-packed array of 10B4C-lined straw tubes employing a very thin and therefore high efficiency 10B4C layer, hence removing the barrier to efficient neutron capture reaction product escape while still providing for efficient neutron capture by providing a plurality of very thin 10B converters, each individual converter element providing efficient reaction product escape. Using such densely packed straw tube detectors of small diameter, a reasonable stack depth allows a high neutron detection efficiency to be achieved on the 1-10 Å wavelength range of thermal neutrons. The position of each interacting neutron can be accurately obtained with for example, resistive charge division readout combined with straw decoding electronics to determine the identity of the struck straw.

Methods and compositions for diagnosing lung cancer with specific DNA methylation patterns

The present invention provides a method for identification of differentially methylated genomic CpG dinucleotide sequences within genomic target sequences that are associated with cancer in an individual by obtaining a biological sample comprising genomic DNA from the individual measuring the level or pattern of methylated genomic CpG dinucleotide sequences for two or more of the genomic targets in the sample, and comparing the level of methylated genomic CpG dinucleotide sequences in the sample to a reference level of methylated genomic CpG dinucleotide sequences, wherein a difference in the level or pattern of methylation of the genomic CpG dinucleotide sequences in the sample compared to the reference level identifies differentially methylated genomic CpG dinucleotide sequences associated with cancer. As disclosed herein, the methods of the invention have numerous diagnostic and prognostic applications. The methods of the invention can be combined with a miniaturized array platform that allows for a high level of assay multiplexing and scalable automation for sample handling and data processing. Also provided by the invention are genomic targets and corresponding nucleic acid probes that are useful in the methods of the invention as they enable detection of differentially methylated genomic CpG dinucleotide sequences associated with cancer, for example, adenocarcenomas and sqamous cell carcinomas of the lung.

Multiregional security system integrated with digital video recording and archiving

A security system is provided in multiple geographic regions having a master server with a master database storing information for access control in each of the regions, and each region has an access control system having a regional server with a regional database storing information for access control in the region, one or more cameras for capturing video data, and one more digital video recorders for storing video data from the cameras. In each region, the regional server receives events from one of the access control system, or other systems which may be present in the region, such as intrusion detection systems, fire systems, or information systems. When received event data is linked in the regional database to a camera in the region, the regional server generates a record to store event video information in the regional database having data representative of the event, the camera linked to the event, the digital video recorder storing video data from the linked camera, and date and time information related to a period of time over which the event occurred. At the regional level, one or more regional video archive servers are provided in each region for archiving video data from the region's digital video recorders. At the master level, a master video archive server is coupled to the master server for archiving video data from the regional video archive servers. If a regional video archive server is not present in a region, video data may be archived from the region's digital video recorders to the master video archive server via the master server. If the video data archived at the regional or master level is associated with event video information stored in a regional database, such event video information is updated to include data representative of the video archive server containing the video data related to the events and the file names under which such video data related to the events are stored on that video archive server.
