Patent CA-2564351-A1 (CA)
Inventor: DUERDEN GEOFFREY D
IPC: H04B3/46
Filed: 2005-05-02
Abstract: A multi-speed jittered signal generator (216,400) that generates a full-speed jittered signal (404) by scaling a low-speed jittered signal (420) using a frequency scaler (428). The low-speed jittered signal is created by injecting a modulation signal (416) into a reference signal (412) using a jitter injector (432). Injecting jitter into a low-speed reference signal allows the full-speed jittered signal to be of higher quality than conventional jitter signals created by injecting jitter information into a full-speed reference signal. The multi-speed jittered signal generator may be used as part of a testing system (208) for testing various circuitry, such as high-speed serializer/deserializer circuitry (220).

Title: System and method for intelligent dynamic message addressing
Inventor: LOVELL ROBERT C JR
IPC: H04Q7/24
Filed: 2005-05-26
Abstract: A method for dynamically modifying the ~from~ address in SCCP-level address in an SS7 message. An inter-carrier vendor (ICV) or intermediary prearranges with a domestic carrier and an inter-network network (e.g., Teleglobe to replace the ICV~s predetermined static ~from~ SCCP-level address with a different ~from~ SCCP-level address. The different address might be selectively or dynamically employed based on an identity of a source wireless carrier, an identity of a destination wireless carrier, a directory number of a source mobile station, or a directory number of a destination mobile station. The different address may also be used to indicate branding or the fact that a carrier has merged or has acquired another carrier.

Title: Perfumed liquid laundry detergent compositions with functionalized silicone fabric care agents
Inventor: SHEETS CONNIE LYNN
IPC: C11D3/16
Filed: 2005-06-30
Abstract: The invention is directed to aqueous liquid laundry detergent compositions for cleaning and imparting fabric care benefits to fabrics laundered therewith and to methods for preparing such compositions. Such compositions comprise (A) at least one textile-cleaning surfactant; (B) droplets of miscible silicones comprising both a polarly-functionalized, preferably nitrogen-containing amino or ammonium functionalized, polysiloxane component and a nitrogen-free non-functionalized or non-polarly-functionalized polysiloxane component; and (C) a perfume component comprising fragrant aldehydes and/or ketones or a pro-perfume capable of providing such aldheyde and/or ketone perfume materials in situ. Incorporation of a polarly-functionalized polysiloxane fabric care agent into liquid laundry detergent compositions by miscibly combining it with a non-functionalized or non-polarly functionalized polysiloxane minimizes the undesirable interaction such polarly-functionalized silicone material might otherwise have with aldehyde and/or ketone perfume compounds.
