Title: Secure processor with external memory using block chaining and block re-ordering
Inventor: CANDELORE BRANT
IPC: G06F1/00
Filed: 1998-10-05
Abstract: A scrambled data transmission is descrambled by communicating encrypted program information and authentication information between an external storage device and block buffers of a secure circuit.  The program information is communicated in block chains to reduce the overhead of the authentication information.  The program information is communicated a block at a time, or even a chain at a time, and stored temporarily in block buffers and a cache, then provided to a CPU to be processed. The blocks may be stored in the external storage device according to a scrambled address signal, and the bytes, blocks, and chains may be further randomly re-ordered and communicated to the block buffers non-sequentially to obfuscate the processing sequence of the program information.  Program information may be also be communicated from the secure circuit to the external memory.  The program information need not be encrypted but only authenticated for security.

Title: Freeze-preventing material and method for preventing pavement surface from freezing
Inventor: ISHIOKA NOBUYA
IPC: C04B41/50
Filed: 1998-10-06
Abstract: A freeze-preventing material comprises cement, salt, and water-absorbing resins. The freeze-preventing material is scattered on the pavement surface in the form of slurry to prevent the pavement surface from freezing. Thereby a freeze-preventing effect is maintained for a long period of time owing to the water-absorbing resins which absorb and retain the salt in large amounts. The anti-freezing effect can be restored by spraying the pavement with the salt again.

Title: Ultrasonic dissection and coagulation system
Inventor: ARANYI ERNIE
IPC: A61B17/28
Filed: 1997-09-30
Abstract: An ultrasonic dissection and coagulation system for surgical use is provided.  The system includes an ultrasonic instrument, a control module, and a handle actuator. The ultrasonic actuator has a housing and an elongated body portion extending from the housing. An ultrasonic transducer supported within the housing is operatively connected to a cutting blade by a vibration coupler. The vibration coupler conducts high frequency vibration from the ultrasonic transducer to the cutting blade. The cutting blade has a cutting surface which is angled with respect to the longitudinal axis of the elongated body portion and, thus, with respect to the axis of vibration. A clamp member having a tissue contact surface is positioned adjacent to the blade member and is movable from an open position in which the tissue contact surface is spaced from the cutting surface to a clamped position in which the tissue contact surface is in close juxtaposed alignment with the cutting surface to clamp tissue therebetween. The clamp member and the angled blade combine to enhance contact between tissue and the cutting surface of the blade member.

Title: System and method for providing enhanced services for a telecommunication call
Inventor: CHRISTIE JOSEPH M
IPC: H04L12/56
Filed: 1997-11-10
Abstract: A system and method provide enhanced services for a call that is transported from a communication device (106) through an asynchronous transfer mode system. The call has user communications (124) in asynchronous transfer mode cells and call signaling (116).  A signaling processor (110) receives the call signaling and processes the call signaling to determine a connection to a service platform (112). The signaling processor transports a processor control message (120) designating the selected connection. An asynchronous transfer mode interworking unit (114) receives the user communication from the communication device and the processor control message from the signaling processor. The asynchronous transfer mode interworking unit converts the user communications from the asynchronous transfer mode cells to a format compatible with the service platform and dynamically transports the user communications to the service platform in real time. The service platform processes the user communications.
