The xAP protocol specifies a special control message, called a heartbeat. Wherever possible, xAP enabled devices and applications are encourage to broadcast this message periodically to provide a network-wide indication of system health. The heartbeat interval is defined at the discretion of the application developer - it is typically of the order of a 15 secs-5 mins depending on the application. xAP promotes the use of regular heartbeats.

Finding the heartbeat can be daunting at first as your baby may be lower than you expect. Make sure you have used a generous amount of coupling gel and position the probe low down on your abdomen. If you do not hear any sound at first, move the probe slowly until you pick up the heartbeat. The fetal heart beat sounds like a galloping horse and is very fast at 120-160 beats per minute. If you still have difficulty then refer to the leaflet enclosed with your Doppler.

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.

Perhaps the baby is positioned in a way that prevents the Fetal Doppler from detecting the heartbeat so you should wait a while and try again. Please refer to our tips on using the BellyBeats Fetal Doppler for specific instructions or feel free to give us a call during our regular customer service hours.

Your baby's heartbeat is much faster than your own. Sometimes it sounds like the fast "clippety-clop" of a galloping horse. You can distinguish your heartbeat from your baby's based on the heart rate, yours being the slower one. When using the Fetal Doppler, you may also hear a "swishing" sound, this is the sound of your blood flow. Please refer to the cassette that is included with the Doppler to familiarize yourself with the differences in the sounds.

The flashing heart icon means that the monitor detected an irregular pulse rhythm during the measurement process. This can be caused by something a simple as body movement or talking during the measurement. If it is displayed frequently and you have remained still and silent during the measuring process, it may be an indication of an irregular pulse or arrhythmia, a potentially serious condition. You should consult with your doctor.

The sound of the fetal heartbeat is distinctive, but can often be confused with other sounds at first. You may well have heard it already during your antenatal appointments with your midwife or doctor. It is a regular fast beating sound, not to be confused with the swishing sound of the placenta. A pulse that is more high-pitched than your baby's heartbeat, but at the same speed. This is the pulse through the umbilical cord; a very pregnant and reassuring noise !

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:

The Home HeartbeatâžÂ¢ 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 concernsâ€"from comfort and convenience to safety and securityâ€"as a challenge that can be addressed by one scaleable solution.

Most mothers are able to hear their baby's heartbeat at the beginning of their third trimester. Some mothers, however, are able to hear the heartbeat at the end of their second trimester.

In the following section, we provide answers to questions that are most frequently asked about DRBD Architecture.

You should hear your baby's heartbeat at the beginning of your third trimester. There are, however, mothers who have told us they heard them late in their second trimester.

On the BigPond Broadband cable network, once you log in, a 'heartbeat' is presented to your computer every five minutes. If your computer does not respond to this, your connection to the Big Pond network will be closed.

Your heartbeat will be noticeably different from your baby's. Please refer to Doppler Tips for more information.

Init scripts are handled as LSBResourceAgent[4]s. Problems with them are quite common and the LSBResourceAgent[4] page contains a series of steps to help you determine if the script is usable or not.

Your midwife should carry an underwater sonic aid so there should be no need for you to stand up. Make sure your midwife has an underwater sonic aid. If she does not, give Jayn a call 08456 123404.

A normal range is usually anywhere from 120-180 beats per minute. Usually, it is very easy to recognize the difference between your own heartbeat and the heartbeat of a fetus is so much faster. Fetal heartbeats commonly sound like a galloping horse. No, it is common to pick the heartbeat up from two different locations. Generally, physicians note the difference in the two heartbeats if twins are suspected.

Yes, by connecting the doppler to your computer or another recording device (using a 1/8" Stereo to 1/8" Stereo Cord). Connect one end to the headphone output on the doppler and the other end to the line in on your computer. If you are using your computer, then just record the heartbeat by using an audio recording program like Windows Sound Recorder.

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.

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.

Only one time of heartbeat time out will standby LB-8000 claim active LB-80000 down. In other words, once the heartbeat signal times out on standby side, the standby LB-8000 will start taking over the active role.

The Home HeartbeatâžÂ¢ system is for people who want to keep in touch with their homes so they can avert emergencies and problems before they get out of control. If you have ever had water damage due to a leaky pipe, left your garage door open, or forgotten to change an air filter, Home HeartbeatâžÂ¢ can help you. The system is also a good fit for your lifestyle if you have:

Home HeartbeatâžÂ¢ components use low-frequency radio chips to form a monitoring network throughout the home. The system performs a "health check" that occurs every 24 hours between the base and all components to ensure they are operating properly.

Batteries are included with the Home KeyTM and all sensors when purchased. The base station is AC powered but optional batteries can be added for protection in case of a power loss. The base station is AC powered with (2), CR123A, 3-volt lithium batteries to keep the system running in the event of power failure. The Home KeyTM runs on a custom re-chargeable lithium ion battery and should provide about two years of service. (Included)

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

There is a CVS repository for Linux-HA. You can find it at http://cvs.linux-ha.org/viewcvs/viewcvs.cgi/linux-ha/ . Read-only access is via login guest, password guest, module name linux-ha. More details are to be found on the HeartbeatCVS page. Heartbeat now uses automake and is generally quite portable at this point. Join the Linux-HA-dev mailing list if you want to help port it to your favorite platform. Due to distribution RPM package name differences, this was unavoidable.
