Title: A ground fault protection circuit for multiple loads with separate gfci branches and a common neutral for the gfci electronics
Inventor: CHAN DAVID
IPC: H02H3/347
Filed: 1998-07-17
Abstract: A ground fault protection circuit for plural loads connected across a power source with plural branches which can be used where the loads are unbalanced. Each branch includes a ground fault circuit interrupter device that has a common line for the electronics of the GFCI separate from the neutral line from the power source to the load where the common lines for the electronics for the ground circuit interrupter devices in each branch are connected to a common point. The ground fault protection circuit employs plural ground fault circuit interrupter devices and eliminates nuisance tripping. The common line for the electronics for a GFCI is routed through the core of the current sensing transformer of the GFCI. The separate neutral line for the electronics, connecting the common lines for the electronics for plural GFCI devices and routing the common lines for the GFCI electronics through the core of the transformer of each GFCI, eliminate improper GFCI operation due to unbalanced loading. The ground fault protection circuit may be used for a three phase power source.

Patent CA-2265105-A1 (CA)
Title: Network based voice mail with call screening
Inventor: MULLER URS A
IPC: H04M1/724
Filed: 1999-03-08
Abstract: A network based voice mail system without losing any of the advantages of traditional answering machines includes a small device, which looks like an answering machine and costs about the same, and three-way calling service. The small device (called a Remote Answering Device) looks just like an ordinary answering machine. It has a speaker, a message number indicator and the basic play back control buttons like "play", "delete", "stop", "rewind", "skip", etc. When a call comes in that is not answered by a human, the Remote Answering Device will pick up after a preselected number of rings and play a prerecorded greeting that is stored locally and then prompt the caller to wait for the beep. The Remote Answering Device then uses three- way calling service to conference the user's voice mail number into the call, by sending a hook flash signal and speed dialing the user's voice mail number. When conference a call is established it plays the beep and then plays the message which is being recording live on the speaker. The caller can skip the greeting by pressing any button, like with most traditional answering machines. After answering a call, the Remote Answering Device constantly senses the impedance of the telephone line to detect if any of the extension phones is being picked up. If an extension is picked up, the Remote Answering Device drops the conference call by sending another hook flash signal and hangs up. The user can then talk normally with the caller. Since the Remote Answering Device answered all calls it knows how many messages have been left and can indicate this number on its display. The user can press a simple "play" button to play back the messages. The Remote Answering Device will automatically call up the user's voice mail box and start playing the messages. If a call is received by the network based voice mail system that did not first pass through the Remote Answering Device, e.g., because the line was busy or out, the network based voice mail system sends a page to the Remote Answering Device that identifies the correct message count in the queue. The Remote Answering Device includes a paging receiver that receives the message and sends the correct count to a processor that updates the message count indicator.

Filed: 1999-04-14
Abstract: A diagnostic platform includes a processor, storage media and user interfaces, including a display screen, the processor being coupled to engine analyzer hardware and adapted to be coupled to a scanner for downloading data from vehicle on-board computers. The system stores libraries of information regarding vehicle identifications, drivability symptoms exhibited by vehicles, vehicle system and component tests and service codes which can be registered by the vehicle on-board computer. System software permits the user to input an identification of the vehicle under test and, in one mode of operation, displays a library of faults, such as symptoms or service codes, from which the user can select those exhibited by the vehicle, whereupon the system selects from the test library those tests pertinent to diagnosis of the causes of the selected faults and displays them in a hierarchically ranked order based on likelihood of successful diagnosis of the faults. The user can then select and initiate any displayed test. In other modes, the system initially displays one of the libraries of system or component tests, from which the user selects those deemed appropriate, whereupon the system highlights icons which can be selected for initiating pertinent test procedures. Selected test procedures may include links to the engine analyzer or scanner hardware or other appropriate test modules.
