Abstract: An improved system for safely and accurately placing intracranial catheters by using techniques from the field of artificial intelligence (AI) which combine the output from in vivo ultrasonic sensors with in vivo video cameras and an embedded inertial measurement unit. The AI subsystem synthesis the output from the three sensors to determine an optimal route to the desired intracranial site while avoiding larger blood vessels en route. Additionally, by using the output from the inertial measurement unit, the catheter's complete trajectory can be recorded and made available for post-operative analysis. The entire system is portable so that it can be used outside of the hospital operating room, for example, in an intensive care unit. Compared to standard freehand methods of placing intracranial catheters, the system embodied here will reduce concomitant hemorrhaging while increasing the accuracy of catheter placement.

Abstract: A method for user authentication for accessing from a client to a server over a packet based network using an one-time password, wherein the client includes a first secret, and the server includes a database for storing a second secret and a chosen username associated with the second secret, wherein the method includes providing the second secret associated with the first secret by the client to the server and storing the second secret and the chosen username in the database; transmitting a challenge from the server to the client; computing the one-time password by the client using the second secret and the random data decoded from the challenge; submitting the one-time password and the chosen username on the client to access the server; validating the one time password received from the client with the one-time password.

Abstract: The present invention provides a system and method for locating survivors after a collapse of a man-made structure. A plurality of electronic devices is distributed in the structure, the electronic devices comprising a wireless transmitter. The devices self-organize into a network and record the positions of the electronic devices in three dimensions relative to each other using a known position of at least one of the electronic devices. Upon the collapse of the structure, at least one additional electronic device is introduced into the network and the positions of the electronic devices are re-calculated using the known position of the additional electronic device. Potential positions of survivors are determined using the re-calculated positions of the electronic devices after the collapse.

Abstract: Data transfer and staging services are common components in Grid-based or more generally in service-oriented applications. Security mechanisms are playing a central role in such services, especially when they are deployed in application fields like for instance e-health. The adoption of WS-Security and related standards to SOAP-based transfer services is, however, not straightforward. With MTOM, SOAP messages can be processed with WS-Security in a straightforward manner. The present invention provides an improved method for signing an MTOM-optimized SOAP message. A non-blocking signature generation approach is proposed enabling a stream-like processing with considerable performance enhancements.
