Title: Apparatus for detecting arcing faults and ground faults in multiwire branch electric power circuits
Inventor: SABOL RICHARD P
IPC: H01H77/00
Filed: 2000-03-10
Abstract: A multiwire branch circuit including two line conductors and a grounded, common neutral conductor is protected by a two pole circuit breaker connected to independently interrupt overcurrent conditions in the two ungrounded line conductors. Three separate protection circuits provide arc fault protection for each of the ungrounded line conductors and ground fault protection for all three conductors. The arc fault detectors use the bimetal of the thermal-magnetic trip device for the associated line conductor for current detection, and therefore, are individually referenced to the associated line voltage. Hence, the outputs of the arc fault detectors are electrically isolated from each other and from the output of the ground fault detector, but operate a common trip circuit to simultaneously open both poles of the two pole circuit breaker. The arc fault detectors have separate isolated power supplies. The ground fault detector is powered by a supply which is energized if either of the ungrounded line conductors is energized.

Patent CA-2306396-A1 (CA)
Title: Displaying and interacting with an informational message based on an information processing system event
Inventor: MAKAR MICHAEL G
IPC: G06F9/44
Filed: 1998-10-16
Abstract: A method and apparatus that addresses the wait-time between an operator and a processing machine by providing the user information during waiting periods. A method is illustrated by the flow diagram (100) of the figure. A processor (101) renders a message (125) for the processor operator's education during times of processor latency (115) such as dialing onto any network such as the Internet. This wait time (117) is normally non-productive and therefore can be used in such a way as to be non-invasive. It is also understood that this time is short so as to make other actions such as getting up form the desk not attractive. Finally even if the wait-time was or became very short the present invention provides the first message (125) to the process operator, that has been frittered. This filtering is a balance of the message owner's willingness to out bid other messages, the time of the day, the location of the operator, and finally the operator's likes and dislikes.
Patent CA-2306599-A1 (CA)
Title: Electromagnetic relay, apparatus and method for making it
Inventor: SATO MASAAKI
IPC: H01H49/00
Filed: 2000-04-26
Abstract: An electromagnetic relay is basically constructed by an insulation base and an armature block. Herein, the insulation base is constructed by a fixed-side terminal set including fixed contacts, a coil block in which a coil is wound about a middle portion of a U-shape iron core, and a permanent magnet, all of which are integrally held together by a fixed-side insulator. The armature block is constructed by a moving-side terminal set including moving contacts and an armature, all of which are integrally held by a moving-side insulator. The armature block is mounted on the insulation base in such a way that the moving contacts are placed opposite to the fixed contacts respectively, and it is supported by a support point to pivotally move on the permanent magnet under an effect of electromagnetic force. Specifically, the fixed-side insulator is made by molding using resin material to integrally hold the fixed-side terminal set, coil block and permanent magnet together at prescribed positions, so it is possible to improve an accuracy in positioning of them. In addition, the fixed-side insulator is formed in a prescribed shape having a contact fixing portion that partly extends to provide engagement portions by which the permanent magnet and U-shape iron core are tightly fixed together under a contact condition where the permanent magnet is placed in tight contact with the side-end portions of the U-shape iron core.

Patent CA-2325254-A1 (CA)
Title: Method and apparatus for creating real-time latency graphs
Inventor: DMITROCA ROBERT W
IPC: H04L12/56
Filed: 2000-11-07
Abstract: The inventive mechanism manages packet delay values that a network incurs in transported data packets. The mechanism uses a plurality of bins for maintaining the number of times that delay values fall within the range of a particular bin. The mechanism also uses a storage array for maintaining delay values that do not fall with the range of the bins. For each delay value that is received, the mechanism determines whether the delay value falls within the bin range. If so, the mechanism increments the number of a particular bin into which the delay value falls within. If not, the mechanism stores the delay value in the storage array and effectively doubles the size of the range of the bins. The mechanism will then effectively re-slot the values into the scaled bins. This allows for the numbers in the bins to used to form graphs detailing the latency of the network for display to a user.
