Granted: 2009-10-06
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-2314213-C (CA)
Inventor: REIMELT RALF
IPC: G01F23/284

Granted: 2004-09-28
Abstract: A level measurement device for measuring the level of material inside of a vessel which includes a conductive element, a signal generating unit and a receiving unit. The conductive element does not come into direct contact with the material being measured. The signal generating unit generates measurement signals which are transmitted along the conductive element. Each of the measurement signals produces an electromagnetic field which travels along the conductive element and is reflected when it reaches the surface of material in the vessel. The reflected electromagnetic field produces an echo signal which travels along said conductive element to the receiving unit. The receiving unit receives the echo signal and determines the level of material in the vessel. The conductive element can be located outside of the vessel. The level measurement device can also include a protective shield which substantially surrounds the sides of the conductive element to prevent interfering radiation from interfering with the signals transmitted and reflected along the conductive element.

Patent CA-2321818-C (CA)
Inventor: GORDON STEPHEN P
IPC: G05D16/20
Filed: 1999-02-24
Granted: 2009-12-29
Abstract: A system (Fig. 16) for metering and dispensing component liquids and solids has a microprocessor-based control system and progressive cavity pumps which provide accurate control of component ratios, shot sizes, flow rates and dispense durations. The system has feedback components (58, 66, 60, 68) for controlling the pressure, flow rates, fluid levels and amounts of fluids dispensed. The pressure in the flow system is used to control the pumps (34, 36) rather than a valved nozzle (49). The system may be used as a sprayer with compressed air added. Back and forth movement of the pump provides compensation for pressure changes. A mold charging system uses pressure to control the pumps which are cycled on and off to avoid overpressurizing the mold. The rate of pressure increase is used to control the rate of flow from the pumps as the mold approaches completion of the charge to avoid overpressurizing the mold.
