Title: Communication system and method providing optimal restoration of failed paths
Inventor: ALLEN JOHN DAVID
IPC: H04Q3/00
Filed: 1996-09-18
Abstract: To restore partial outages within a communication network (200) comprising switching nodes (201) interconnected by links (202, 203), a three-stage distributed restoration protocol (420-434) is activated to use spare links and restore normal network connectivity. The protocol detects and resolves contention for spare resources among separate restoration processes in the event of multiple simultaneous failures. A conservative flooding approach is used during an initial forward signaling stage (424, 426). Data elements added to the forward signals convey the likelihood that the path will be needed for restoration. A reverse signaling stage (428, 430) uses reverse signals with attached contention data to alert the restoration processes contending for spare resources. A final path implementation stage (432, 434) involves reviewing the reverse signals and using the attached contention data to make informed choices of restoration paths that result in the highest degree of overall network restoration.

Title: Method and apparatus for establishing the legitimacy of use of a block of digitally represented information
Inventor: MARTINEAU PIERRE
IPC: G06F21/00
Filed: 1997-01-03
Abstract: Method and apparatus for establishing the legitimacy of use of a block of digitally represented information residing in a computer of a user. The block of digitally represented information may be a text file, a sound recording, a graphical file or a software file. The computer includes a program that processes the selected file to generate a substantially unique identification code. The code is transmitted to a server that contains a listing of files correlated to status data, indicative of whether the file is proprietary material and the conditions associated with its use. If the server locates an entry in its database it retrieves the status data and transmits it to the user's computer. In the event the identification code issued by the user's computer is not sufficiently discriminative, i.e., it does not allow the server to uniquely identify the file, the server transmits an algorithm identifier to the user's computer allowing the file to be re-processed with a new algorithm to generate a more distinctive identification code.

Title: Clot capture coil
Inventor: GOBIN Y PIERRE
IPC: A61F2/00
Filed: 1997-01-31
Abstract: A clot and foreign body removal device is described which comprises a catheter with at least one lumen. Located within the catheter is a clot capture coil that is connected to an insertion mandril. In one embodiment, the clot capture coil is made out of a solid elastic or superelastic material which has shape memory, preferably nitinol. The elasticity or superelasticity of the coil allows it to be deformed within the catheter and to then reform its original coil configuration when the coil is moved outside of the catheter lumen. In another embodiment the coil is a biphasic coil which changes shape upon heating or passing an electric current. Once the coil configuration has been established, the coil can be used to ensnare and corkscrew a clot in a vessel. A clot is extracted from the vessel by moving the clot capture coil and catheter proximally until the clot can be removed or released into a different vessel that does not perfuse a critical organ. Foreign bodies are similarly captured by deploying the coil distal to the foreign body and moving the clot capture coil proximally until the foreign body is trapped within the coil. By removing the device from the body, the foreign material is also removed.

Patent CA-2256192-A1 (CA)
Inventor: RINGLIEN JAMES A
IPC: G06T7/40
Filed: 1998-12-15
Abstract: Infrared and visible light energies are directed through a container onto a CCD camera that is responsive to both the visible and infrared light energy.  Crossed polarizers are positioned on opposed sides of the container, and operate on the visible light energy in such a way as to block transmission of visible light to the camera in the absence of stress variations in the container, which alter polarization of the visible light energy traveling through the container. On the other hand, the polarizers have little or no effect on the infrared light energy, which creates a normally gray intensity of background light at the camera. In this way, incidence of visible light on the camera due to stress variations in the container appears as a bright signal against a normally gray background, while blockage of infrared light due to opaque variations in the container appears as a dark signal against the normally gray background.

Inventor: ARIA BEHRAD
IPC: A61N1/365
Filed: 1997-09-16
Abstract: A method and apparatus for measuring impedance of heart tissue or the leads associated with a cardiac stimulation apparatus involves charging a capacitor, storing the value of the voltage across the capacitor when charged, discharging the capacitor into said lead/heart system and storing the voltage on said capacitor when discharged. The two voltages may then be used to determine the combined impedance of the lead and the heart tissue. This may be advantageously accomplished by using separate circuits to measure each of the voltages of the capacitor and storing those voltages. These voltages then may be applied to an analog-to-digital converter which converts the ratio of said voltages to digital form. This value can then be used to calculate the combined impedance of the heart tissue or the lead. If one of the two impedances is known the other can then be easily determined.
