Patent CA-2328464-A1 (CA)
Title: Arc fault protected electrical receptacle
Inventor: GRATTAN BRIAN G
IPC: H01R4/36
Filed: 2000-12-13
Abstract: An arcing fault protection assembly in an electrical outlet, and a corresponding method determine whether arcing is present in circuits connected to the outlet. The assembly comprises a sensor, a broadband noise circuit, and a controller. The sensor detects a current and develops a corresponding sensor signal. The broadband noise circuit determines the presence of broadband noise in the sensor signal and produces a corresponding output signal. The controller processes the sensor signal and the output signal in a predetermined fashion to determine whether an arcing fault is present. The sensor, broadband noise circuit, and controller are mounted to the outlet receptacle or to an outlet box which houses the receptacle.

Title: Internet protocol-based computer network service
Inventor: ORTHODOXOU MARK
IPC: H04L29/12
Filed: 2001-01-31
Abstract: The system is an Internet Protocol-based computer network service that when installed, allows connected computers access Internet Protocol-based services if they are configured for any Internet Protocol-based network. This is different from a conventional Internet Protocol-based network in which connected computers must be configured specifically for that network to access Internet Protocol-based services or to have custom applications running on them to allow this access. These services include, but are not limited to, World-Wide-Web browsing, sending and/or receiving electronic mail, file transfer, and multimedia conferencing. The system supports any service that is Internet Protocol-based. The system is completely software-based. That is, it is a set of algorithms that are run on a computing platform. The platform that is executing the algorithms (the server) is a stand-alone system. No proprietary software is installed on the client.

Title: Clock synchronization in telecommunications network using system frame number
Inventor: KARLSSON MARCUS
IPC: H04W92/00
Filed: 1999-12-17
Abstract: A telecommunications system (18) capitalizes employment of a system frame number (SFN) for synchronizing plural real time clocks (206) provided at one  or more nodes of the network. System frame signals (e.g., pulses) are distributed from a source (210, 310) to processors (202) having slave clocks  (206S) that need to be synchronized with a master clock. A master processor (202M, 302T) sends a clock set message (500) to the processors, the clock se t message including a reference master clock time (506) and a reference system  frame number (504). The recipient processors which receive the clock set message resynchronize their respective slave clocks using the reference mast er clock time and the reference system frame number. In one mode, the clock set  message directs the recipient processors to set their respective slave clock s to the reference master clock time upon the recipient processors obtaining t he reference system frame number. In another mode, the clock set message advise s the recipient processors of an actual master clock time at the reference system frame number, thereby enabling the recipient processor to calculate a n adjusted slave clock time.

Title: Dna encoding the human serine protease eos
Inventor: CHEN CAILIN
IPC: C12P21/08
Filed: 2000-08-18
Abstract: Here we describe the molecular identification of a cDNA encoding a novel serine protease we have termed protease EOS. The deduced amino acid sequence, and its alignment with other well-characterized serine proteases clearly indicates that it is a member of the S1 serine protease family. We have found that the protease EOS mRNA is expressed in platelets and leukocytes and more specifically eosinophils and possibly macrophages. Although this protease is abundantly expressed in ovary, retina and stomach, where it may perform important functions, its expression in platelets and certain cells of the immune system suggests that it may play roles in thrombosis and in the immune process. Enzymatically active protease EOS is amenable to further biochemical analyses for the identification of physiological substrates and specific modulators.
