Abstract: An apparatus and method for scanning an object with a helical CT scanner, the method comprising: acquiring an amount of data corresponding to the object that is scanned by the CT scanner, wherein the amount of data is generated by an x-ray source that projects a fan beam of x-rays toward a detector array on an opposite side of a gantry of the CT scanner, the fan beam being generated at multiple x-ray source positions as the x-ray source is rotated about the object as the object passes through an opening in the gantry disposed about a conveyor for moving the object through the opening; monitoring a position of the conveyor as the object passes through the opening in the gantry; determining if the conveyor has been stationary for more than one rotation of the gantry and discarding redundant data after one rotation, optionally turning off the x-ray tube if the conveyor has been stationary for more than one gantry rotation, and if so preventing the conveyor from moving again until the tube is turned on and is sta

Abstract: An apparatus and method for providing a projection image directly from data acquired by a CT scanner, the method comprising: acquiring an amount of data corresponding to an entire object that is scanned by the CT scanner, wherein the amount of data is generated by an x-ray source that projects a fan beam of x-rays toward a detector array on an opposite side of a gantry of the CT scanner as the object is passed through an opening in the gantry; selecting an imaging plane, the imaging plane corresponding to a view of the object; dividing the imaging plane into a plurality of rows and columns, thus creating a grid of points corresponding to the imaging plane; determining, for each point in the grid, a data point from the acquired data corresponding to an x-ray source position wherein a ray from the x-ray source to the grid point is closest to a perpendicular orientation with respect to the imaging plane, and a detector position where the ray intersects the detector array; and presenting a projection image corres

Abstract: A method for developing a virtual representation of an x-ray diffraction imaging system includes generating a symmetry axis, generating a conical shape having a base diameter, a vertex angle ?, and a vertex point, locating the vertex point at an origin point on the symmetry axis, and extending a first line and a second line between the vertex point and the conical base such that the first line is separated an angle d? from the second line in an azimuthal direction around the conical base.

Abstract: A system and method for controlling execution of an interpreted language. Statements of the interpreted language to be executed by a script engine are intercepted by a protection module and control is passed to a script helper module that is asociated with the script engine. The script helper module establishes a secure communications channel with an authorization component and passes the statements and an authorization request to the authorization component. The authorization component sends a reply to the script helper module which either permits the script engine to execute the statement or cancels the attempted execution. When the script engine is loaded, a list is updated identifying the script engine. If a script helper module is not present for the loaded script engine, a boot-strap loader is called to load the script helper module. A special information block contains data as to the location of the interception points.

The drive member includes a protrusion, the edges of the protrusion forming first and second driving surfaces which define a free space of at least about 90° there between. The driven member includes a protrusion, the sides of the protrusion form a first and a second driven surface, respectively. The drive member is adapted to be operably connected to between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member are disposed for relative rotation in substantially the same plane such that the driven member protrusion moves in the free space defined by the driving surfaces of the drive member protrusion.

Abstract: The invention is directed to techniques of facilitating document transmission from one entity through an electronic communications network. An entity may be a legally recognized person such as a corporation, partnership, organization, government, individual, and the like. As a legally recognized person, an entity may act as a principal with respect to one or more authorized agents. Furthermore, as a legal person, an entity may authorize one or more of its agents to use fax transmission equipment such as the fax certification system described herein. The techniques of this invention assure a second entity that a first entity has indeed authorized its agent to send a document from a fax station under the controls of the first entity.

Abstract: A door closer comprises a spindle journaled in a housing and connected to turn with a door. Upon rotation of the spindle, a cam carried by the spindle effects linear movement of a slide assembly relative to the housing. A piston is connected with the slide assembly. Passages are provided in the housing to permit flow of fluid in the housing in response to movement of the piston. A spring assembly disposed outside of the housing is connected to the piston. Rotation of the spindle and cam during door opening moves the slide assembly, thereby compressing the spring assembly for storing energy for urging the piston and the slide assembly in the opposite door closing direction.

Abstract: A system and method for enabling use of detailed consumer profiles for the purposes of targeted information delivery while protecting these profiles from disclosure to information providers or hostile third parties are disclosed herein. Rather than gathering data about a consumer in order to decide which information to send her, an information provider makes use of a client-side executable software module called a negotiant function. The negotiant function acts as a client-side proxy to protect consumer data, and it also directs the targeting of information, requesting items of information from the information provider that are tailored to the profile provided by the consumer.

Abstract: A touch bar (24) exit device (20) comprises a retractor element (50) disposed in the housing (22) for substantially restilinear movement. The retractor element (50) connects the touch bar (24) and the latch bolt (82) such that the retractor element (50) and the latch bolt (82) are moved toward the retracted position in response to movement of the touch bar (24). An electrically energizable locking mechanism (104) in the exit device (20) includes a reciprocating plunger (106) moving transverse to the retractor element (50). When energized, the locking mechanism (104) is operative to move the plunger (106) to the projected locking position to prevent retraction of the latch bolt. A time delay circuit is connected to the locking mechanism (104). A switch (120) actuated in response to movement of the touch bar (24) is connected to the time delay circuit for starting a predetermined time interval for temporarily delaying deenergization of the locking mechanism (104).

Abstract: A web application security scanner (WASS) includes a login manager configured to perform an automated login to a web site. The automated login may be performed when the login manager detects that a login session has ended. The login manager is configured to determine credentials for the web site to allow the WASS to access the web site. The WASS may then use the credentials to continue scanning the web site. Thus, previously unscannable web pages may be accessed in the web site because of the automated login process.

Abstract: Unauthorized entry into controlled access areas using tailgating or reverse entry methods is detected using machine vision methods. Camera images of the controlled area are processed to identify and track objects in the controlled area. In a preferred embodiment, this processing includes 3D surface analysis to distinguish and classify objects in the field of view. Feature extraction, color analysis, and pattern recognition may also be used for identification and tracking of objects. Integration with security monitoring and control systems provides notification when a tailgating or reverse entry event has occurred. More reliable operation in practical circumstances is thus obtained, such as when multiple people are using an entrance or exit under variable light and shadow conditions. Electronic access control systems may further be combined with the machine vision methods of the invention to more effectively prevent tailgating or reverse entry.
