LB-8000 sends heartbeat signal through both Network 1 and serial port. Only when backup fails to get heartbeat signals from both interfaces will the failover happens.

The heartbeat protocol uses UDP port 694 to send a UDP message from network 1 interface to other LB-8000. Backup manager keeps listening to port 694 and waiting for the heartbeat UDP packet sent from the primary manager, through both Network 1 and serial port interface. If primary manager is working normally, it will send a UDP packet through each Network 1 and serial port periodically.

The Integrated Student Information System (ISIS) will not be replaced until Phase 3 of the project. There will be several interfaces between ISIS and the Integrated System to transact business in the areas of financial aid and collection and recording of tuition and fees. Other systems (e.g., Maximo) may never be replaced by the Integrated System if they offer unique features required by the specific business operation.

Every WAPM has a heartbeat function. The heartbeat's frequency and resolution is configurable (refer to each WAPM's specifications). The heartbeat function is like a watchdog, a WAPM will communicate with its WPIM at least once every hearbeat period. If a WPIM misses two heartbeats in a row from a WAPM, then the WPIM asserts a "loss of RF communications" trouble signal to the ACP. (back)

The full-size pre-color display iPod models -- the original iPod, iPod 2G, iPod 3G, iPod 4G, and iPod U2 Special Edition -- all use Chicago, the same font used for the original Macintosh interface.

The Page1 History Interface is for plotting time histories of nodes, elements, materials (parts), and global data. This data can be from d3plot, d3thdt, or d3iff files which are binary files output by LS-DYNA.

I got this message "ERROR: No local heartbeat. Forcing shutdown" and then Heartbeat shut itself down for no reason at all!

Every node writes every two secs to its block in the heartbeat system file. The block offset is equal to its global node number. So node 0 writes to the first block, node 1 to the second, etc. All the nodes also read the heartbeat sysfile every two secs. As long as the timestamp is changing, that node is deemed alive.

The model will not replace experiments, but it will allow experiments to be much more focused and better optimized. In a sense the model can be used to design the ideal experiment and then test the experiment before moving to a final version animal experiments. So it will definitely save the slow road of trial and error and exploration in animal experiments.

The Linux-HA project (http://www.linux-ha.org/) offers a high availability solution commonly referred to as Linux Heartbeat. Linux Heartbeat ships as part of several Linux distributions, as well as within several embedded high availability systems. This solution can also be used for other applications besides databases servers, such as mail servers, web servers, file servers, and DNS servers. Linux Heartbeat implements a heartbeat-protocol.

The V.24 serial interface is quite simply best suited for this application. Its connection cable can be extended to almost any length and does not produce long-wave interference. USB has a maximum cable length of 8 metres and high interference levels. The same goes for other interface types. This is simply not true. See previous question. There may be radio clocks for which this applies; for the NeoClock it is not true. This is also not true.

Yes, Monitor one does provide a web interface (powered by Apache). The number of concurrent web-interface users is undefined, which means, is not determined by technical or programmatic limitations.

The earphone jack of the R5 doubles as the interface for a PC connection (using an appropriate cable).

Yes, Windows XP will have a "newer" look to it but will still have the basics of Windows we have grown accustomed to. The one that is debuted at the EMP is the "Luna" theme.

Applications built using JFC are not locked in to a specific look and feel. Using JFC, developers can create apps that either have a native platform look and feel or use the Java look and feel -- or they can create their own custom look and feel. The power lies in the hands of developers -- they can develop their products using the look and feel that is most appropriate for their users.

The Heartbeat Award is a national scheme promoted by and managed on a local basis by local authority Environmental Health departments in partnership with various Northamptonshire County Council departments. It is a prestigious award which can gain good publicity for the restaurant, pub, takeaway, school or caterer concerned. The Heartbeat Award requires caterers to:

Don't Panic! Your baby could just be positioned in a way that the Doppler can't locate the heart beat. Try again in another part of your belly, or walk around before trying again. If you still cannot locate the heart rate, make an appointment to see your health care provider.

The Home Heartbeat??? system is the first personal awareness system for the home. It provides homeowners with anytime knowledge of the inner workings of their homes while they go about their daily lives by adding simple remote monitoring to ordinary household devices and systems. It treats all homeowner concerns - from comfort and convenience to safety and security - as a challenge that can be addressed by one scaleable solution.
