An inspection system that can detect contraband items concealed on, in or beneath an individual's clothing. The system employs mm wave radiation to detect contraband items. The system is described in connection with a check point security system that includes temperature controlled walls to enhance imaging of contraband items. Also, a mm wave camera is used in conjunction with a camera that forms visible images. To address privacy concerns of displaying images of people made with mm wave cameras that effectively “see through” clothes, the mm wave images are not displayed directly. Rather, computer processing produces indications of suspicious items from the underlying raw mm wave images. The indications of suspicious items are overlaid on the visible image.

The present invention relates to the definition, in a flight plan, of the horizontal profile of an air route with vertical flight and speed profile prescribed on departure and / or on arrival, by a stringing together of check-points and / or turn points associated with local flight constraints and called “D-Fix” because they are not listed in a published navigation database like those called “Waypoints”. It consists in charting, on curvilinear distance maps, a direct curvilinear path joining the departure point to the destination point of the air route while complying with vertical flight and speed profiles prescribed on departure and / or on arrival and while guaranteeing a circumnavigation of the surrounding reliefs and compliance with regulated overfly zones, then in approximating the series of points of the direct curvilinear path by a sequence of straight segments complying with an arbitrary maximum deviation threshold relative to the points of the series and an arbitrary minimum lateral deviation threshold relative to the set of obstacles to be circumnavigated and in adopting as “D-Fix” points the points of the intermediate intersections of the rectilinear segments.

Embodiments of the invention are directed to a system, method, or computer program product for providing expedited loading / inserting of data by an entity. Specifically, the invention expedites the loading / inserting of large quantities of data to database tables. Initially received data for loading is processed, via multi-row insert, onto in-memory or temporary tables. The data is staged on a temporary table while the appropriate base table is determined. Once determined, data from the temporary table is pointed to the base table. In this way, a massive amount of data loading from the temporary table to a base table may occur. This prevents logging and locking associated with adding individual data points or row to a base table independently. Errors are check and processed accordingly. Once updated, the data on the temporary table is deleted in mass and a check point restart is issued.

This invention concerns a database computer system and method for making applications recoverable from system crashes. The application state (i.e., address space) is treated as a single object which can be atomically flushed in a manner akin to flushing individual pages in database recovery techniques. To enable this monolithic treatment of the application, executions performed by the application are mapped to logical loggable operations that can be posted to the stable log. Any modifications to the application state are accumulated and the application state is periodically flushed to stable storage using an atomic procedure. The application recovery integrates with database recovery, and effectively eliminates or at least substantially reduces the need for check pointing applications. In addition, optimization techniques are described to make the read, write, and recovery phases more efficient. Atomic flush sets, whether generated from cyclic flush dependencies or otherwise, can be broken apart. This enables an ordered flushing sequence of first flushing a first object and then flushing a second object, rather than having to flush both the first and second objects simultaneously and atomically.

A CPU displays an image on a display device with reference to an image location table stored in advance in a RAM. When coordinates on the image are sequentially designated by an input device, the CPU sequentially compares the locations specified by the designated coordinates with those of checking points stored in the image location table. The CPU determines that the operator is authorized when errors or differences between the locations compared with each other are within an allowable range and when the order of designation of the coordinates is appropriate.

An apparatus for motion estimation and method therefor are provided. The apparatus includes a processing element (PE) array unit that includes a delay unit array and a PE array. The delay unit array outputs different data flows of current data to the PE array with respect to checking points in one step of an N-step seach algorithm, while a regular data flow of reference data is fed into the PE array. One search step of the N-step search algorithm for motion estimation can be performed while the pixel data of a search area is read in a regular pixel scan order. When the search area is read completely, the search step is completed. In this way, the PE array unit achieves the N-step search algorithm. Further, the PE array unit can be configured to perform half-pel motion estimation with respect to a best point found in a full-pel search.

An endpoint on a network uses detection data to detect a malicious software attack. The endpoint identifies content associated with the attack, such as a component of a web page, and generates a description of the content. The endpoint sends the description to a security server. The security server analyzes the content and identifies characteristics of the content that are present when the content is carried by network traffic. The security server generates a traffic signature that specifies the identified characteristics and provides the traffic signature to inspection points. The inspection points, in turn, use the traffic signature to examine network traffic passing through the inspection points to detect network traffic carrying the content. The attack detection at the endpoint thus informs the traffic signature-based detection at the inspection points and reduces the spread of malicious software.
