Title: Compensating for leakage inductance in a switch mode power supply
Inventor: PIPER JOHAN
IPC: H02M3/335
Filed: 2008-05-23
Abstract: A switch mode power supply (SMPS) output current regulation system comprises a snubber circuit 17,18,19 providing a path for leakage inductance current to flow in the primary winding after a power switching device 15 has switched off; a controller 20 that senses currents in a transformer 11 of the SMPS and drives the power switching device to regulate the output current; and a system to compensate the current sense signal for the leakage inductance current. The amount of compensation can be determined from an initial value of leakage current when the switch is turned off and estimating the duration of the leakage current discharge time. A capacitor 19 of the snubber circuit can store a charge representing an average value of leakage current that is compensated by subtraction from the current sense signal, the capacitor being reset by a switch 22 while the leakage current discharges. The leakage discharge time may be estimated using a circuit (fig 4) that integrates the primary voltage VA at two rates depending on the drive pulse width. The circuit enables constant voltage and accurate current limiting operation (fig 10) using primary-side sensing.

Title: Method and system of material identification using binocular stereoscopic and multi-energy transmission images
Inventor: XIE YALI
IPC: H04N13/239
Filed: 2008-08-01
Abstract: A system for material identification in radiographic imaging for large sized objects combines binocular stereoscopic and multi-energy transmission imaging techniques. The method first creates template depth planes of objects along the depth direction in a detection space by means of the binocular stereoscopic technique. Depth plane grey images of the objects are then reconstructed (grey reconstruction) from the transmission image. Finally the multi-energy technique is applied to identify the materials of the objects for which the reconstruction of corresponding grey images in depth plane succeeded. The method comprises the following steps: causing two angled x-ray beams to penetrate through objects under examination so as to obtain data of left and right transmission images, segmenting said left and right transmission images and matching the results of said segmentation; creating a template depth plane along the depth direction of the transmission images; reconstructing a depth plane grey image from the transmission images; repeating the above process on transmission images of variation energy to obtain a template depth plane of each depth plane for the variation energy; merging the template planes for different energy levels at the same depth to obtain a template depth plane for each depth plane and energy of a predetermined group of energy levels; identifying the material of the objects for each of which the grey reconstruction in depth plane succeeds. With the method, any obstacle that dominates the ray absorption can be peeled off from the objects that overlap in the direction of a ray beam. The object that is unobvious due to a relatively small amount of ray absorption will thus stand out, and the material property of the object, such as organic, mixture, metal and the like can be identified. This method lays a fundament for automatic identification of harmful objects, such as explosive, drugs, etc., concealed in a freight container.

Title: Method and system for document comparison using cross plane comparison
Inventor: VISAN TIBERIU
IPC: G06V30/10
Filed: 2007-06-28
Abstract: The invention relates to the field of document authentication and more specifically to an apparatus and method for validating an enhanced feature contained in a document under analysis. More specifically, a cross plane comparison is used within a document comparison system to validate the authenticity of a security document. Two images are extracted from two colour planes (e.g. visible light and infrared) of a specified page of a security document and the presence/absence of a pattern or text in each plane is determined. In operation, the security document is exposed to two light sources and grey scale images are extracted. Binary images are then obtained from the grey scale images by filtering each grey scale image and then thresholding each grey scale image. The difference between the two binary images is then calculated to determine if a pattern or text is present in both planes or only in one plane. A confidence score is determined from the difference and is presented to an operator of the document comparison system.
