Title: System and method for determination of incremental value at risk for securities trading
Inventor: GARMAN MARK B
IPC: G06Q40/04
Filed: 1997-01-24
Granted: 2003-04-08
Abstract: A system, method, and product determines the incremental impact of any number of candidate trades on the value at risk (VaR) measure of a trading portfolio within a trading interval, without requiring that the VaR measure be redetermined individually with respect to each candidate trade. The method includes determining the VaR measure for the trading portfolio, and determining a derivative vector quantity for the VaR measure. For each candidate trade, the impact of the candidate trade on the VaR measure is determined as the vector product of the derivative vector and the mapped cashflows of the candidate trade. A negative sign indicates a desirable reduction in the VaR measure. This determination may be made for any number of candidate trades without having to re-determine the VaR measure. The software product employs this method in a financial analysis application in an optimized implementation. The system includes the software product along with databases storing the trading portfolio(s). Additionally, the method and product allow each candidate trade to be normalized with respect to selected criteria, so that a number of individual candidate trades may be ranked with respect to their incremental impact on the VaR measure to determine the candidate trade the best reduces the VaR measure.

Abstract: A fast position tolerant and economical fingerprint verification algorithm and software implementation is disclosed. The algorithm has very important advantages in comparison to existing fingerprint verification algorithms like minutia extraction or full image analysis based on series of two dimensional fast Fourier transforms (FFT's) and two dimensional cross correlation in speed, compactness of the template and finger positioning for verification. It is based on a small "yardstick" pattern being moved inside the image to be verified, and when a match is found the rest of the verification process is started. The yardstick is divided into segments in order to fit different DSP  and microcontroller register lengths and structures. The software code implements the algorithm in the most efficient way for utilization on a digital signal processor architecture. A main area of application is in fingerprint identification and verification, but it could be implemented with same success in other image verification systems like iris, eye, face etc., where two images should be compared. The algorithm is adaptive, so various false acceptance and false rejection coefficients could be utilized very easily. It also produces a very compact template, which leads to better memory utilization in fingerprint databases.

Abstract: A latching mechanism for attachment to a boat trailer and for securely latching onto the U-bolt typically found on a boat bow includes an integral weldment providing a pair of oppositely-disposed side plates and a cooperating support plate positioned therebetween.  Assembled to the side plates are a pair of alignment cones which help to guide and direct the bow of the boat and in particular the U-bolt into the latching mechanism.  The support plate defines a receiving channel having a closed base and an open entrance.  A pair of spring- biased latching jaws are pivotally attached to the support plate on opposite sides of the receiving channel and are normally positioned in a closed and latching condition.  Each latching jaw includes a tip portion and the two tip portions are oriented so as to extend inwardly toward each other and across the open end of the receiving channel.  As the U-bolt moves into the open end of the channel and pushes against the tip portions, the latching jaws spring open, allowing the U-bolt to position itself within the receiving channel.  At this point the latching jaws close back and prevent the U-bolt from exiting the receiving channel.  In order to free the U-bolt from the latching mechanism, a release member is provided which is manually pushed in between the two latching jaws to separate those jaws and allow removal of the U-bolt.

Granted: 2002-10-22
Abstract: A seal cartridge (11) particularly suitable for artificial lift pump rod sealing and for other applications where a rotating drive shaft penetrates a  pressurized reservoir which is filled with abrasive laden liquids, mixtures or slurries. The cartridge (11) exploits a pressure responsive area of a wear sleeve (19) to eliminate internal bearing (13) running clearance in order to  achieve a true-running rubbing surface which is conducive to the longevity o f the compression-type rotary seals (21, 23, 27) which are employed. A cartrid ge mounting mechanism (9) is incorporated which overcomes stuffing box to rod ( 7) misalignment, and is readily adaptable to pumps made by different manufacturers. The cartridge (11) provides for leakage annunciation in the event of failure of a redundant rotary seal (21, 23, 27), and also provides for automatic pump shut down if a primary rotary seal fails. A redundant sealing arrangement between the wear sleeve (19) and rod (7) is incorporated  which is relatively immune to installation damage, and to damage resulting from rod run out and vibration. By incorporation of a split drive clamp (39) , the cartridge (11) is able to exploit space within the pump yoke which is ordinarily reserved for the occasional use of rod clamps. The cartridge (11)  also incorporates an active cooling system (71) which dissipates heat generated by the seals and bearings.

Title: Stereo photographic system
Inventor: INABA MINORU
IPC: G02B27/22
Filed: 1998-11-24
Granted: 2003-03-18
Abstract: A stereo photographic system capable of reproducing a correct stereo image by improving the precision of positions for mounting the films on a stereo slide mount. Positions of the projected images of perforation of the films relative to the focusing plates are measured when a suitable perspective feeding is obtained by using a detecting device that projects the pictures of the films onto a pair of right and left focusing plates and that adjusts the gap between the right and left projected pictures to adjust the perspective feeling. A printer device 81 drives a printer head 87 based upon the position data that are measured, and prints indexes on a base frame 51a of the stereo slide mount to accomplish the positioning with respect to the perforations. When the films are mounted in a manner that the indexes of the base frame 51a are in agreement with the perforations of the films, the offset amount of the pictures of the films relative to the windows of the stereo slide mount is fixed to a position relatively equal to the offset amount of the projected pictures relative to the focusing plates detected by the detecting device.
