Nasa Adapts Pulse Oximeter Technology For Space Travel

NASA has always been in the forefront of ground breaking technology for many years now, and they are not slowing down anytime soon. Even as the United States economy has shrunk the budget of the agency, it has not let this challenge to get in the way of progress. NASAs missions include various trips into space and specifically the Russian controlled space station. Ever since the agency came into existence, they have focused on astronaut safety before anything else. The value of life amongst the agency is high, and no missions goal precedes it. There have been accidents in the past where brave astronauts have lost their lives. We have even seen instances where civilians on missions have lost their lives like in the case of shuttle Columbia. In order to maintain the health of its astronauts, the agency strives to both develop and adopt technology that helps it monitor the health of its astronauts. The monitoring of various vital signs provides mission specialists a direct view of the conditions experienced by the astronauts, and any challenges that they may be encountering. Some of these challenges might not even be known to the astronauts, but mission control is always one step ahead whenever possible.

A recent tool that has been adopted into NASA and its various missions is the pulse oximeter. A pulse oximeter, also known as a pulse ox by some medical professionals, is a medical device used to measure the blood oxygen saturation and pulse rate of individuals. These are important factors of the human body, because they provide data that can be used to determine how efficient the lungs and heart are at any given point of time. In the past a pulse oximeter was a bulky tabletop unit only seen in clinical settings, but with recent advances in technology all that has drastically changed. A new fingertip pulse oximeter is smaller than most cell phones, and runs on standard batteries. NASA is working on using a finger oximeter to develop a device that is the same size, but transmit its data to mission specialists via intermediate hardware and software. NASA is also going to adapt on their pulse oximeter to withstand harsher conditions that are not present here on Earth. Variances in temperature and pressure are big factors to consider when creating products to be used in space.

A pulse oximeter has again proven its ability as a necessary tool for the monitoring of health conditions of patients.

Office Technology Checklist

Is your business growing and in need of more office space? Or perhaps you are remodelling your old office and want to update your look. If this is the case, you may want to think about updating your technology as well. Although it may require a little extra money and some more effort, having the right computers, cordless headsets, and other electronics can make your and your employees’ work easier and more convenient to do. If you are interested in updating your technology, here is a technology checklist that may help you.

Cordless headsets- Technology Checklist

Do you still use the same electronics you purchase ten years ago? Here are a few items you may want to bring into the times.

Computers- Not every computer is made alike. One may be able to run certain programs you need, while another may not have the capability. When you decide to purchase a computer, don’t choose one for how it looks. Find one that will be able to help you accomplish the work you must get done to be successful.
Cordless Headsets- Technology has come a long way. Once of the newest and most talked about advances is Bluetooth. With cordless headsets and Bluetooth, your employees will no longer be held down by wires and distance. They will be able to efficiently perform their work while conversing with and listening to customers through the headset.
Telephones- Once you have your cordless headsets, you must update your phone system so it is Bluetooth ready. Some phone systems simply need an adaptor to allow employees to switch quickly from their regular office phone to a headset. Other phone systems may come completely Bluetooth capable.
Security System- In order to protect your network and your employee information, it is important for you to update your security system as well. Consider using a two factor authentication system to keep track of who can and can not access pertinent information about your business.
Fax Machine- In today’s world, no one has time to wait for important information to be sent through regular snail mail, especially when it comes to businesses. If the information can not be scanned and sent in an email, it will most likely be faxed. Make sure your office has an updated fax machine capable of sending and retrieving important data.
Copier– Even though many companies have attempted to go green, copies of real paper are still needed each day in the office. Some copiers are better than others, producing more copies in less time. Certain copiers also can produce colour copies, which may be important to your business.

 Quality Cordless Headsets- If you are redesigning your corporate office, consider using this technology checklist to update your electronics. You may find using certain electronics, like new computers, fax machines, cordless headsets, and Bluetooth capable phones will allow your employees to become more efficient at work. They are also more likely to complete all the tasks assigned to them every day because they will have the technology available to help them.

Lighter Than Air Technology

Lighter than air technology was very popular at the beginning of the twentieth century, but the Hindenburg disaster in 1937 caused people to lose interest in this type of aircraft.

Since then there has been new research and development for both civilian and military applications. Innovations in materials and other technology has caused a renewed interest in lighter than air devices.

Lighter Than Air Aircraft

All lighter than air vehicles use a lifting gas to provide their lift. The most common types of lifting gas used (since hydrogen was banned after 1937) are helium and hot air. Blimps use helium and large balloons use hot air. One thousand cubic feet of hot air has a lifting capacity of approximately twenty pounds. One thousand cubic feet of helium will lift approximately three times that of hot air or sixty pounds. Hydrogen has a lifting capacity that is approximately ten percent higher than helium.

Common Applications

Blimps and balloons are usually what come to mind when someone mentions lighter than air aircraft. These are unique and large enough to draw attention. They have applications in aerial photography, aerial advertising, surveillance and sports events. Radio controlled

blimps make a very cost effective platform for flying billboards. The retention of seeing an ad on the side of a blimp is much greater than the television, radio and static written ads that we are exposed to all of the time. The radio-controlled blimp is ideal for video photographic needs. They can fly much lower than a fixed wing aircraft and are less expensive to operate than a helicopter.

Near Space Applications

Near space is defined roughly as that region above controlled air space (approximately twelve miles high) to about sixty miles high (lower limit of space.) This region offers advantages for both civilian communications and military applications over the present satellite system in use today.

One advantage would be cost savings. Putting satellites into orbit is very expensive. Another is safety. Think how crippling it would be if one or more of our satellites stopped functioning. It would be much faster to get a vehicle into near space than getting one or more twenty thousand plus mile into space.

Our communications needs for both voice and data are increasing at an exponential rate. Future wars are going to be fought and won by technology. Data to satellites travels at the speed of light, but there is a delay to travel twenty thousand miles up and twenty thousand miles back vs. traveling sixty miles up and sixty back. This delay could be important if you are trying to lock on to a missile pointed in your direction.

There is an increasing need to develop lighter than air platforms that can be parked in this near space region. Tests have shown that line of site communications can be increased from ten miles to over four hundred miles by utilizing near space platforms. This offers a tremendous advantage for both civilian and military communications. Having several of these platforms will provide the ability to cover thousands of square miles areas.

Several companies and universities are doing research on near space vehicles. If you do a search on the web using a poplar search engine you will find over two million entries.


Lighter than air technology has many advantages, however, there are engineering obstacles that have to be solved before it is used in large quantities. The volume required to lift a payload that is practical will limit some applications. There will always be a need for satellites, but lighter than air vehicles will provide increased capabilities for future needs.

Screaming at work is not the correct strategy for dealing with conflict. Whether you are a manager or an employee, screaming is just not the right approach to deal with your boss, your co-workers or your employees. When managers take on a screaming approach, then employees think that screaming is okay. But overall screaming just is not good for business.

What do customers think when they are at the counter waiting to purchase your high quality services or products and they find that the employees are have an out and out screaming match?

It really doesn’t even matter what the topic is. The customer feels uncomfortable. What should they do? Do they say “excuse me”? Or do they wait patiently for the match to end, or perhaps they just leave their items on the counter and walk out. What happens to the customer after they leave your business? Are they speaking highly of your customer service? Do they want to return or do they feel a new service provider — your competition.

When there is fighting at work it decreases your business effectiveness. There is an impact on the customers and there is a detrimental impact on your staff and managers. For staff, they feel angry, uncomfortable, hurt and possibly many other emotions.

There is an impact on their work performance as well and it is a negative impact. They may even feel depressed and/or helpless; that they are powerless to change the environment and make it a good place to work. For managers, if they are the screamer, they may actually feel fearful and be dealing with their fears as a manager with loud outbursts. The manger may also feel helpless as they have created a pattern of behavior that they are unsure how to change.

Screaming behaviors do need to be changed by both managers and employees.

For employees, managers/leaders need to give staff alternatives through coaching and training they must teach new behaviors and coach staff on how to make needed changes. Boundaries of acceptable behaviors should be outlined for staffs. For managers, business owners and leaders take on the responsibility to recognize the impact of this behavior and seek out resources to make necessary changes. They too, can outline boundaries of acceptable behavior for managers and let them know that screaming is not acceptable. The impact of terminating employees and managers is severe. It is worth investing in coaching and training to make changes in behavior. Good coaching combined with training can have dramatic impacts on these types of behaviors.

Through this combination new skills can be learned and then practiced. Creating a coaching culture can be the long term goal. By teaching managers how to use coaching skills to work with staffs over controlling, screaming, and dis-empowering will all be addressed. Managers will take a new approach that is focused on employee empowerment and engagement, increased innovation and a collaborative team environment. The results are happier employees and manager; ultimately your company becomes a good place to work.
