GPS Systems – The Pros and Cons

The requirement of a global navigation system was recognized during the Second World War. Hence, the invention of GPS System (Global Positioning System) had taken place in the year, 1973. The USDOD (United States Department of Defense) had great contributions in this invention. However, in 1994, it became fully accessible for the public.

Within few years, other super powers had also started developing their own GPS systems like the Russian Global Navigation Satellite System (GLONASS), the European Union Galileo Positioning System, Compass Navigation System of China and Regional Navigational Satellite System of India.

The following points would highlight the advantages of this worldwide navigating system.

  • It regularly gives weather updates especially during your outdoor activities.
  • It plays a major role in surveying the unfavorable features of land. These features range from volcanic eruptions, high falls, trenches, floating icebergs, hot springs to plate movements of Earth. These detailed surveys are very much required for the construction purposes of transport, building, communication and drawing boundaries for property ownership.
  • GPS system fitted in your car can prove to be highly beneficial in times of traffic jams. They provide a proper direction to avoid these jams thus saving a lot of your precious time. It can even save your car from theft. These navigators with the help of satellites give the correct location of your lost car and inform the required authorities about it. Therefore, weather forecast and positioning maps make one feel comfortable during on road journeys.
  • Tracking down the movements of children has become lot easier for their parents with GPS machines. They not only give the information of their tracks but also about the other hideouts. Even the lost pets can come back to their masters with this positioning system.
  • The size can be as small as a button or the dial of a watch. Hence, portability is no more a barrier for your tracking exercise.
  • You can also keep an eye on the truck movements carrying your goods. It adds a safety quotient to your business.
  • It also seems to be quite good in predicting the damages or problems in various structures thus preventing forth-coming disasters.

Electronic Stethoscopes – Advantages and Disadvantages

Electronic stethoscopes carry many advantages and disadvantages that your non-electronic stethoscopes may not feature. For starters the electronic stethoscope is obviously going to have a far more amplifying ability than an acoustic stethoscope. By the mere touch of a button on your digital stethoscope you are ensuring that you are getting closer and closer to a sound that will provide a diagnosis. These amplified sounds are something new in the auscultation arena in which stethoscopes are used, and it should come to no surprise to you when your co-workers are left in awe with such dramatic capabilities your fancy stethoscope displays.

These sounds can even be recorded by most electronic models and some models even come with computer software that enables the capability to view the sound waves. These models that come with software are more expensive and the medical professional should ask herself what will be the purpose of this instrument in the long term. The cardiology and pulmonary departments should take particular interest in electronic stethoscopes. Of course these two departments have utilized non-electronic stethoscopes for decades and have successfully operated, but what the electronic stethoscope can provide is a revolutionized way of ausculatating that perhaps should be practiced exclusively by cardiologist and pulmonologist.

The disadvantages of purchasing these stethoscopes should also be acknowledged. Particularly because they are expensive and you do not want to spend so much money on an instrument that is really not going to make you a better professional. Electronic stethoscopes have a tendency to suffer from interference when other electronic instruments like cell phones are around. Batteries are a huge turn off for those using digital stethoscopes and are always on the run in the work place. Troubleshooting this battery issue of course requires a little discipline. Storing batteries away in a nearby drawer that you know is easily accessible at any time is a must, especially if a patient is waiting. Knowing how to quickly install the batteries is necessary if the electronic stethoscope is going to be used on a daily basis. Another known fact about digital stethoscopes is that they are very expensive. Even the ones made from cheap material can range from $150-$200 and the more expensive models can be double.

But let me not stress you out! The advantages far outweigh the disadvantages, however it is important to note that these electronic models are not made for everyone so considering the above mentioned facts is crucial because again, you are going to spend some serious money with these high tech instruments.

Use of Two Way Radios While Caring for the Elderly

The proportion of the elderly to the total population in the US is a significant 12.9%, according to figures from the Administration of Aging. In addition, the percentage is expected to increase to 19% by the year 2030. The best way to take care of this section of the population is to remain connected to them while helping them remain safe and independent. The advancement of technology has led to the development of several unique communication systems that allow the elderly to contact their loved ones at any time. One of these is two way radios.

These days more and more elderly people prefer to spend their retirement days in the luxury and safety of their own homes rather than senior citizen homes or homes for the elderly. This is possible by refurbishing their existing homes to include the latest communication systems that make it easier to communicate with the outside world, along with other amenities designed specifically for the elderly or infirmed. Two way radios have emerged as a highly popular communication product that allow the elderly to remain in touch with their care givers and loved ones, whether they are spending time working in the garden, relaxing in the living room or playing golf two way radios provide security and piece of mind. Two way radios are also equipped with special features that can prove useful for these tasks.

Need for Two Way Radios for the Elderly

As a person grows older their physical health deteriorates and many of their vital organs may not function to the full capacity. Failing eye sight, weak muscles, and the inability to move around fast are some of the common problems that may hinder the daily activities and free movement of an elderly person. This makes them prone to accidents and illnesses that need timely attention. Speed becomes a mater of life and death. Although a caregiver can provide his/her full attention to taking care of the elderly, the latter may not wish to lose their independence. The best way to take care of the elderly while allowing them their independence is by using an effective two way communication system, such as radios. This ensures that both the parties can contact each other any time they wish to do so. A caregiver can even go out for their routine tasks without worrying about the elderly person if he/she knows that there is an effective two way communication system between them.

Using and Buying Two Way Radios for the Elderly

A caregiver’s time is usually spent attending to the basic needs of the elderly and this task can be simplified by using two way radios as an effective channel of communication. A simple push of a button allows you to communicate with your loved ones while doing other household chores. One might ask- why not use mobile phones? A major advantage offered by two way radios over mobile phones is they don’t have to rely on any mobile network and communications are instantaneous.

Based on the concept of radio frequencies that are always present in the air, the two way radios operate almost anywhere. This means the elderly can take them wherever they go, with the assurance that they can contact anyone in times of emergency or even when they wish to pass on a simple message. The elderly often wish to engage in a variety of activities, such as gardening, going walks, visiting the library or just pursuing their hobbies. The presence of a two way radio will encourage them to undertake these activities freely without worrying about how to get in touch with their care giver in times of need. Quick communication is very important in case of mishaps and accidents.

Two way radios have a built in transmitter, antenna and speaker. These radios may come with an internal rechargeable battery that can be charged by plugging it into the power outlets or with standard replaceable batteries that can be easily bought from the market. You can choose whichever one is more convenient for you. These radios use two types of frequencies:

  • Family Radio Service- In this case transmission is possible up to two miles. Also, no license is required and usage costs are very low.
  • General Mobile Radio Service- Such two way radios are designed for long range communication. However, you need to get a license for using this service.

Benefits of Two Way Radios for the Elderly

Some of the benefits of two way radios are:

  • These radios are very sturdy and continue to work even if they are dropped, submitted to the effects of rain, dust or sand and operate in extreme temperatures.
  • They are very easy to use and require only the push of the button to talk.
  • The hand held models can easily be attached to your belt or other accessories leaving your hands free to do other work.
  • They can be used anywhere so you can carry the device around with you at all times.
  • They are not expensive. You can communicate at very low costs without relying on any type of cell phone services. You do not have to pay any monthly charges, any roaming charges or choose from various monthly plans.
  • Some two way radios also provide you with regular alerts about weather conditions and warn you of possible hazardous weather.
  • You can choose from a variety of designs and models, such as handheld devices or wireless base station intercoms.
  • The two way feature of these radios allows the caregivers to regularly check on the well being of the elderly. This is highly useful as the elderly who often have hearing problems may not be able to hear your voice from the other room.
  • These radios also have inbuilt features like an LED torch and an LCD display.
  • You can use them for short as well as long distance communication depending on the type of model you pick.
  • Some models can easily be submersed in water for about half an hour or so without any damage, thus allowing elders to carry these radios while swimming or bathing.
  • These two way radios are even ideal for usage by the physically disabled.

Apart from usage in households, two way radio systems are also highly useful in nursing homes. Here again the focus is on providing timely attention to the elderly and this is possible through instant communication.

A variety of two way radio models are available in the market and many of these offer several unique features. When choosing a two way radio system, you study the various features and their utility for taking care of the elderly. You need to choose one, which can be easily carried and operated by the elderly in your home. Before you purchase a system, check for its Ingress Protection or IP rating. The IP rating signifies the two way radio’s resistance to foreign objects and moisture. Look for a radio that is easy to hold and carry and features buttons that are clearly visible. These two way radios are available with varied price tags that range from under $50 to hundreds of dollars.

Once you’ve bought the system you need to take certain precautions to ensure that it operates effectively – ·

  • First you should check that the antenna is firmly attached and operational.
  • Always ensure that the batteries are fully charged. This will ensure that communications are clear. ·
  • Test the signal quality from time to time to ensure that the two way radio works properly. The signals should be loud and clear for effective communication. This is even more important as older people may not be able to speak loudly.
  • Always end your messages with ‘over’, when the final message is sent. This is an indication for the listener that your message is complete and that they can carry on with their work. ·
  • Educate the elderly on how to use the two way radio system for communication.

Taking care of the elderly can be taxi on the care giver, both mentally and physically but can be simplified with the use of two way radio communication systems.

Please, Just Say No to Emojis! These Apps Corrupt the Ford Sync System!

Using emoticons on your smartphone can cause severe problems with the voice-to-text functions of the Ford Sync System. This self-help article reveals ways to correct these problems.

Since late 2012 there were numerous problems with the iPhone 5, iPhone 4 and iPhone 4S as well as the Samsung Galaxy, the HTC Evo and other smartphones having connectivity issues with the Ford Sync system. User forums for these smartphones and for the Sync system have been filled with people which connectivity problems that affected the base model, the MyFord and the MyFord Touch Sync systems. The issue was something was seriously affecting the Sync users accessibility of their phone book contacts with Voice commands. If you pushed the “Voice” icon on your steering wheel and said “Phone” and then “Call + (your contact name)” then your Sync system might reply, “Calling Dot on Cell.”

Some of the issues were a result of smartphone users downloading and using any of the Emoji Apps. The word emoji is Japanese for ideograms, you know, those little emoticons such as smiley faces, “frowny” faces, etc.

The new Apple iOS even allows iPhone 5 users to go to their Settings folder, to the General settings, to the Keyboard tab, and then to the next menu to select “Keyboards.” You can then tap “Add New Keyboard” and add an emoji keyboard. However, this is the kiss of death for your Sync system.

The issue is that the cute emoticons seen on your smartphone screen as a smiley face are, in fact, long strings of programming language which cause Sync’s text-to-voice conversion to go haywire. When given a Voice command to call a contact the system will say “Calling Dot on Cell” and then dial the first contact listed in your phone book.

If this has happened, then review EVERY phone contact and remove any emoticon. Also remove any extraneous exclamation points, periods, commas, dashes and so on that you might have in your phone contact list. Be sure to even check the name of your device! Some overzealous users renamed their phones with smiley faces on the device name. Check to see that everything is cleared again. Then go to your Bluetooth settings and remove Sync from your phone.

If you have an iPhone, do a soft reset. This is done by holding your “Home” button, the large button at the lower center of your front screen, while also holding down the Power button at the top edge of the phone on the right side. Hold these buttons down until the Apple icon appears. Then release the buttons. Let the phone go idle for a few minutes. You can further push the power button, then slide the on-screen button to power down the phone. Leave the phone off for a few minutes. Then push the power button and let the phone power back up.

Then go to your vehicle. Go to your phone settings and delete your phone from the list of Bluetooth devices. Then turn your vehicle off. Open the hood and find the car battery. Loosen and remove the black (negative) battery cable) for about five minutes. Then replace the cable and tighten the clamp. Close the hood and restart the vehicle. Let a few minutes pass before resetting the radio from AM and resetting the clock. Then go to your phone settings and pair your phone back. See this video for instructions on pairing a phone.

Yes, this is a lot to do. This is why you need to really clean Emoji Apps and emoji keyboards from your phone files. Emoticons are cute but they defeat the whole purpose of having a Bluetooth-enabled hands-free communications system. Maybe it’s time to say bye, bye to smiley faces! So sorry!
