Abstract: A method and apparatus for detecting and recording an event is disclosed which includes a scintillator located to receive energy from the event. The energy may be x-ray energy from a radiographic source. A mirror is optionally angularly located adjacent the scintillator to redirect or reflect the light into two or more lenses. The two or more lenses have zoom capability to adjust the size of the image and the two or more lenses are arranged as telecentric lenses. A camera receives the light presented from the two or more lenses on an image plane to establish a recorded image while a shutter is presented to selectively control presentation of the light to the camera. The zoom lens allows use of different size scintillators and various CCD cameras to benefit from multiple zoom positions to best capture the image generated by the scintillator.

Abstract: A method and system of enforcing a computer policy uses a central server to manage user profiles, policies and encryption keys. The server securely supplies the keys to client devices only after checking that the policy has been complied with. The checks include both the identity of the user and the machine identity of the client device. The keys are held in a secure environment of the client device, for example in a Trusted Platform Module (TPM), and remain inaccessible at all times to the end user. Theft or loss of a portable client device does not result in any encrypted data being compromised since the keys needed to decrypt that data are not extractable from the secure environment.

Abstract: A community safety system (CSS) including a notification management entity (NME) comprising servers, the NME communicatively coupled to multiple user devices and one or more administrator devices (collectively, registered user devices). The CSS includes a plurality of registered users, wherein each registered user is associated with an organization, and a user category of a set of user categories. The NME may maintain a list of the registered users and associated information. The registered users may have user devices including a CSS application operating thereon. In some embodiments the CSS enables inter-organizational communication, allowing for members of a first organization to provide alerts that the NME can pass to a second organization when the registered user is physically located within a security zone associated with a second organization but not a member of the second organization.

Abstract: A system for reflecting and recording x-ray radiation from an x-ray emitting event to characterize the event. A crystal is aligned to receive radiation along a first path from an x-ray emitting event. Upon striking the crystal, the x-ray reflects from the crystal along a second path due to a reflection plane of the crystal defined by one of the following Miller indices: (9,7,3) or (11,3,3). Exemplary crystalline material is germanium. The x-rays are reflected to a detector aligned to receive reflected x-rays that are reflected from the crystal along the second path and the detector generates a detector signal in response to x-rays impacting the detector. The detector may include a CCD electronic detector, film plates, or any other detector type. A processor receives and processes the detector signal to generate reflection data representing the x-rays emitted from the x-ray emitting event.

Abstract: A probe including reflector is disclosed to measure the velocity distribution of a moving surface along many lines of sight. Laser light, directed to the surface by the probe and then reflected back from the surface, is Doppler shifted by the moving surface, collected into probe, and then directed to detection equipment through optic fibers. The received light is mixed with reference laser light and using photonic Doppler velocimetry, a continuous time record of the surface movement is obtained. An array of single-mode optical fibers provides an optic signal to one or more lens groups and a reflector, such as a parabolic reflector having a mirrored interior surface.

Abstract: The interaction of a plurality of users with a computer system is monitored and measurements are made of different features of this interaction such as process creation, registry key changes, and file system actions. These measurements are then analyzed to identify those features that are more discriminatory. The set of features is then used to develop for each user a model of his/her interaction with the computer system that can then be used to authenticate that user when interacting with the computer system at a later time. Advantageously, these steps are performed automatically and may be performed periodically or even continuously to verify that each user of the computer system is indeed the individual he/she purports to be. Illustratively, the feature extraction is performed using Fisher's criteria; and the user model is developed using a Gaussian mixture model. A method for updating the user model is also disclosed.

Abstract: A method of authenticating a network client to a relying party computer via a computer server comprises the computer server receiving a transaction code from a token manager via a first communications channel. The network client is configured to communicate with a token manager which is configured to communicate with a hardware token interfaced therewith. The network client is also configured to communicate with the relying party computer and the computer server. The computer server also receives a transaction pointer from the relying party computer via a second communications channel that is distinct from the first communications channel. Preferably, the transaction pointer is unpredictable by the computer server. The computer server transmits an authorization signal to the relying party computer in accordance with a correlation between the transaction code and the transaction pointer. The authorization signal facilitates authentication of the network client to the relying party computer.

Abstract: A photocathode designs that leverage the grazing incidence geometry yield improvements through the introduction of recessed structures, such as cones, pyramids, pillars or cavities to the photocathode substrate surface. Improvements in yield of up to 20 times have been shown to occur in grazing incidence geometry disclosed herein due to a larger path length of the X-ray photons which better matches the secondary electron escape depth within the photocathode material. A photocathode includes a substrate having a first side and a second side, the first side configured to receive x-ray energy and the second side opposing the first side. A structured surface is associated with the second side of the substrate such that the structured surface includes a plurality of recesses from the second side of the substrate into the substrate.
