Abstract: Systems and methods are disclosed herein for verifying the integrity of a remote computing device. The system includes a challenge processor in communication with a communication device. The challenge processor selects a challenge from a plurality of challenges for determining the integrity of a computer program on a remote computing device. The challenge is selected in a manner which is substantially unpredictable by the remote computing device. The communication device transmits the challenge to the remote computing device and receives an output of the challenge. The challenge processor is also configured to determine from the output of the challenge whether the integrity of the computer program on the remote computing device has been compromised.

Abstract: Systems and methods are disclosed herein for detecting a threat to a computing device. The system includes a server and a computing device in communication with the server and configured to browse the Internet. The server receives data indicating a configuration parameter of the computing device and executes an emulation of the computing device that replicates the configuration parameter. The server also receives data relating to the computing device's browsing behavior and replicates the browsing behavior on the emulation. Upon detecting an undesired modification to the emulation of the computing device caused by the replicated browsing behavior, the server automatically generates and outputs an alert related to the undesired modification and related browsing behavior.

Abstract: Network virtual link mapping methods and systems are disclosed. In some method embodiments, router configurations are parsed to determine virtual link information for a network. A map is derived for virtual link information associated with a customer. The map is displayed, and may be used for highlighting problem areas for a customer, recommending solutions, and reconfiguring the virtual links to address specific customer needs.

Abstract: A system having an integrated network and customer database is provided. The system retrieves router configurations to create the integrated database, which includes port data for each port on each router in each network. The system may determine the impact of proposed actions on routers. The system may process network events to display the status, port data, and customer data for each port. The system may respond to user input by polling a router and displaying the real time status, port data, and customer data for each port on the router.

Abstract: A system having a data retriever and a database manager is provided. The data retriever retrieves router configurations from data stores for routers. The database manager parses the router configurations to determine port data for each port on each router, and integrates the port data with customer data to create an integrated database. The database manager also determines a customer link diversity based on the integrated database and displays the customer link diversity. The database manager can recommend reassignment of a customer link when the customer link diversity is less than a corresponding target customer link diversity. The database manager can also determine the customer link diversity when adding a card and determine the customer link diversity when adding a customer link.

Abstract: A system and method for photoacoustic tomography of a sample, such as a mammalian joint, includes a light source configured to deliver light to the sample, an ultrasonic transducer disposed adjacent to the sample for receiving photoacoustic signals generated due to optical absorption of the light by the sample, a motor operably connected to at least one of the sample and the ultrasonic transducer for varying a position of the sample and the ultrasonic transducer with respect to one another along a scanning path, and a control system in communication with the light source, the ultrasonic transducer, and the motor for reconstructing photoacoustic images of the sample from the received photoacoustic signals.

Abstract: An optimized elastic modulus reconstruction procedure can estimate the nonlinear elastic properties of vascular wall from intramural strain and pulse wave velocity (PWV) measurements. A noninvasive free-hand ultrasound scanning procedure is used to apply external force, comparable to the force in measuring a subject's blood pressure, to achieve higher strains by equalizing the internal arterial baseline pressure. PWV is estimated at the same location where intramural strain is measured. The reconstructed elastic modulus is optimized and the arterial elastic modulus can be determined and monitored using a simple dual elastic modulus reconstruction procedure.

Abstract: The present invention is a miniature illuminating Christmas tree intended to create a decorative display in the window of a home, car, or office. In the preferred mode, the tree-shaped ornament is made from plastic and artificial green Christmas tree material and contains an illumination source, such as blinking LEDs, fiberoptics, or bulbs configured according to a previously determined pattern. A power source, such as at least one battery, is housed in the base or trunk of the ornament. The device is removably attached to a window through usage of one or more suction cups, and may be reversed, allowing the user to display the object on the outside or the inside of the window in question.

Abstract: An x-ray CT system performs a scan by acquiring projection views from which an image is reconstructed. In a prospective embodiment, the correlation of adjacent views is calculated as the scan is performed and is used to detect subject motion as the scan is being performed. In a retrospective embodiment, the correlation of adjacent views is calculated and is used to detect subject motion after the scan is completed. In the first embodiment substitute projection views are acquired by continuing the scan and in the second embodiment redundant projection views acquired during the scan are substituted until the best possible image is produced.

Abstract: An ultrasonic imaging system acquires echo signals from an object being imaged such as a moving coronary artery and the cross-correlation between echo signals is employed as an objective measure of relative object location. The method is used in a prescan procedure to determine an optimal gating window to acquire image data during a cardiac gated scan, and it is used during the scan as a real time gating signal.

Abstract: Methods and systems for measuring mechanical property of a vascular wall and a method and system for determining health of a vascular structure are provided wherein local deformation of a vessel wall resulting from physiologic pressures with altered transmural forces is measured. A non-invasive free-hand ultrasound scanning-procedure was performed to apply external force, comparable to the force generated in measuring a subject's blood pressure, to achieve higher strains by equalizing the internal arterial baseline pressure. When the applied pressure matched the internal baseline diastolic pressure, strain and strain rate increased by a factor of 10 over a cardiac cycle. Radial arterial strain was assessed in the vessel wall over the entire deformation procedure using a phase-sensitive, two-dimensional speckle-tracking algorithm. An elastic modulus reconstruction procedure was developed to estimate the non-linear elastic properties of the vascular wall.
