Patent CA-2341945-A1 (CA)
Inventor: HAUN ANDY A
IPC: H02H3/44
Filed: 2001-03-22
Abstract: An arcing fault protection assembly and a corresponding method determine whether arcing is present in electrical circuits. The assembly powers-up quickly without dissipating excessive heat while power is being supplied to the assembly. The assembly comprises a sensor, a broadband noise circuit, a controller, and a dual-mode power supply. The sensor detects a current flowing in an electrical circuit 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 in the circuit. The dual-mode power supply supplies power to the sensor, broadband noise circuit and controller using a first mode and later switching to a second mode. The first mode reaches steady state faster than the second mode.

Title: System and method for providing a proxy farp for legacy storage devices
Inventor: WILSON STEPHEN K
IPC: H04L12/42
Filed: 1999-09-23
Abstract: A method and system in a fibre channel network (10) for discovering the location of a storage device (20, 30) that does not support the fibre channel address resolution protocol FARP using a FARP broadcast and a storage router (18) as a proxy. The storage router (18) determines the node names of each storage device (20, 30) connected to it and save the node names to a look-up table (22). The router then sends a FARP request to each storage device on the table and for each device that responds, flagging the corresponding node name for that storage device as FARP compatible, and for each device that does not respond, flagging the node name as not being FARP compatible. When a FARP  broadcast directed to any of the storage devices is received at the router, the router determines if the device is FARP compatible by accessing the look-up table and if the device is not FARP compatible, sends a reply to the FARP  broadcast that contains the physical address of the device.
