Title: Mapping function and method of transmitting signaling system 7 (ss7) telecommunications messages over data networks
Inventor: GLITHO ROCH
IPC: H04L12/64
Filed: 1998-11-27
Abstract: A mapping function (31) and method for mapping a Signaling System 7 (SS7) telecommunication signaling message (30) from a Signaling Connection Control Part (SCCP) protocol layer (33) to an Internet Protocol (IP) protocol layer (32) in order to transmit the SS7 signaling message over a data network (53) from an origination node (51) to a destination node (52). The mapping function receives the SS7 signaling message from the SCCP protocol layer by sending and receiving Message Transfer Protocol (MTP) primitives from the mapping function to the SCCP protocol layer. The mapping function then maps the received SS7 signaling message into an IP message by mapping MTP primitives (43) into IP primitives (44), mapping the SS7 message address into an IP message address, and utilizing a user interface (34) to set IP protocol parameters that cannot be transferred by the SCCP  protocol layer. The mapping function (31) then sends the mapped IP message to the IP protocol layer (32) by sending and receiving IP  primitives from the mapping function to the IP protocol layer.

Patent CA-2315552-A1 (CA)
Inventor: IOUDOVSKI ALEXEI
IPC: G06F17/50
Filed: 2000-08-09
Abstract: A computer process for extracting logic gates and/or functional cells from a transistor netlist. The process comprises the steps of scanning the netlist for transistor blocks of p-type and n-type transistors, determining if the p-type transistors and the n-type transistors are complementary or non-complementary and identifying the logic gate for each of the complementary transistor blocks and/or the functional cell for each of the non-complementary blocks. A transistor block is a group of p-type transistors connected through their sources and drains between a power node and a common node, and a group n-type transistors connected through their sources and drains between a ground node and the common node. Complementarity may be determined by iteratively seeking the serial connections and the parallel connections for the p-type transistors and the n-type transistors, identifying the main p-type transistor branch and the main n-type transistor branch, and comparing the branches.

Title: Safety circuit for an elevator installation
Inventor: LISI ANTONIO
IPC: B66B1/34
Filed: 2000-10-05
Abstract: This safety circuit (1) consists of a series chain (2) of contacts (3), at least one safety relay (4), an electric power supply (5), and a monitoring device (6), the signal from the safety relay (4) being transmitted to an elevator control (7). The voltage across the safety relay (4) which is to be regulated is tapped at point (P1) and transmitted to a network (14) which is connected to the voltage converter (10). If all the contacts (3) of the series chain (2) are closed, the voltage across the safety relay (4) is held constant. Regulation of the voltage across the safety relay (4) makes the safety circuit (1), with respect to voltage drop, independent of the length of the cabling connecting the contacts (3).

Title: Prevention of deadlocks and livelocks in lossless, backpressured packet networks
Inventor: KAROL MARK JOHN
IPC: H04L12/56
Filed: 2000-10-05
Abstract: A packet communication network is arranged so that a backpressure or feedback signal is sent from a receiving node to a node having packets to send to the receiving, node, selectively allowing only certain packets to be considered eligible for transmission. The backpressure is arranged to be lossless, and to avoid network deadlocks and livelocks. The transmission of a packet from a sending node to a receiving node via a link, is controlled by sending from the receiving node to the upstream node a feedback value that assures that there will be room in the buffer in the receiving node to store packets subsequently received from the upstream node; assigning a priority level to packets stored in the buffer of the receiving node; and transmitting from the sending node to the receiving node, only those stored packets at whose priority level exceeds the feedback value received from the receiving node.

Title: Use of corneal hardening agents in enzyme orthokeratology
Inventor: KARAGEOZIAN VICKEN
IPC: A61K9/00
Filed: 1999-03-09
Abstract: An Enzyme Orthokeratology method is provided for correcting refractive errors in the eye of a subject mammal. Accelerating reshaping of the cornea is accomplished by administering a corneal hardening amount of a corneal hardening agent to the eye of the subject. Reformation is accomplished under the influence of a rigid contact lens or a series of lenses having a concave curvature that will correct a refractive error. The cornea rapidly reshapes its convex curvature to the concave curvature of the contact lens, rendering the eye emmetropic. The cornea is permitted to "harden" to retain the new emmetropic shape. After "hardening" has occurred, the lens rendering the eye emmetropic is removed.

Filed: 2001-04-02
Abstract: A combustor of a gas turbine includes a combustion tube acting as a combustion chamber. In the combustion tube, a cylindrical heat insulating member is disposed and forms a wall of the combustion chamber. Numerous cooling air passages are formed in the heat insulating member and extending in the axial direction between cooling air inlet disposed at one end of the heat insulating member and cooling air outlet disposed at the other end of the heat insulating member. The heat insulating member is attached to the inner surface of the combustion tube at its cooling air inlet side end and a seal ring is disposed around the outer circumference of the heat insulating member at a portion between the cooling air inlet side end and the cooling air outlet side end. The seal ring is made of heat resistant material and prevents cooling air flowing through the annular space between the inner surface of the combustion tube and the outer surface of the heat insulating member.      Since cooling air flows through the annular space around the outer surface of the heat insulating member, all of cooling air flows through the cooling passages in the heat insulating member and is used for cooling the heat insulating member. Therefore, the cooling capacity of the heat insulating member increases.
