Ocean-Going Enterprise Sets Sail Next Year

Published by:

At the time of writing, we know more about the surface of Mars than we do about the delicate complexities of our terrestrial oceans.

However, next year, a daring and innovative new project is seeking to change all that.

Sea Orbiter, referred to be some as the “starship Enterprise for the water” will be a new type of ocean-going research vessel, a moving laboratory that will hopefully allow Human scientists better access to the world’s oceans than ever before.

Designed by French architect Jaques Rougerie, Sea Orbiter will allow scientists to study everything from underwater archaeological sites to the migration patterns of marine life. It is also expected to extensively map the ocean floors beneath it and to allow divers to work continually on deeper dives than ever before.

Diving to a depth greater than 50 meters or so can cause decompression illness (DCI) and the only way to traverse this obstacle is via saturation diving, which involves prolonged immersion in hyperbaric pressure chambers. Aboard the Sea Orbiter, however, the entire bottom deck will feature hyperbaric pressure levels so that divers can regularly dive to greater depths, but still enjoy a comfortable standard of living when out of the water.

Theoretically, this means that divers will be able to reach depths of up to 100 metres, day after day, simply by remaining in Sea Orbiter’s bottom deck. Also, because the researchers will be diving via a special bay on the underside of the craft, they will be unencumbered by obstacles like bad weather and lack of daylight. In fact, due to this advancement, Sea Orbiter is expected to give researchers unprecedented access to as-yet unknown deep-sea creatures that are only observable at night.

Technology wise, the design appears to have been influenced by the International Space Station (ISS), another innovative project that allowed researchers to reside in their chosen location for long periods of time, something that is always a great boon to scientific research.

Sea Orbiter will also boast mini, remote-operated submarines, as well as a manned submersible capable of reaching depths up to 1,000 metres and an unmanned drone that will be capable of venturing an astonishing 6,000 metres below sea level.

The design of the craft itself is also equally innovative; in fact, the word genius could be applied with little/no hyperbole present. Basically, the craft’s tall, conical shape will render it almost impossible to tip, allowing Sea Orbiter to brave even the most violent ocean storm and emerge unscathed.

In fact, Sea Orbiter is far more stable than most other seafaring vessels. The saucer section in the middle of the craft, and the keel directly below it, are both far denser than seawater itself, which would normally be enough for it to sink like a stone, however, the upper portion of the vessel is designed to be exceptionally buoyant and will only be fashioned from the lightest possible materials, meaning that although two thirds of Sea Orbiter will be perpetually submerged, the vessel itself should never actually capsize or sink.

If Sea Orbiter is successful, this design is expected to become the model for a great many future ships.

Solar and wind power will keep Sea Orbiter’s engines running, with biofuel on standby for use as needed. This means that Sea Orbiter will be one of the greenest post-industrial vessels ever to sail the oceans of the world and, once again, could become a valuable prototype for the oceangoing vessels of the future.

Heavily influenced by the works of Jules Verne and the pioneering naturalist work of filmmaker and explorer Jaques Cousteau, Jaques Rougerie has designed underwater environments for much of his career, even participating in a World Record setting 71-day stint under water. His work to date has included sub aquatic museums and laboratories and glass bottom research vessels.

He has also created workable designs for underwater habitats such as houses and even entire villages.

Construction of the Sea Orbiter is expected to be completed by 2016, but the project’s success still hinges on funding. To date, the French government has provided most of the development money, but the project has also been backed by numerous corporate sponsors and even a public crowd-funding campaign.

If Sea Orbiter’s initial mission is successful, Rougerie and his team are planning to build an entire fleet of Sea Orbiters, which could potentially make their collective task the most comprehensive study of the Earth’s oceans that has ever been undertaken.

What’s an Earpiece?

Published by:

I don’t know how you came here as you read it on social media, twitter, facebook, google +, stumble upon or anywhere else. But thank you for visiting and I hope you like reading this as much as I did.

Broadly speaking, an earpiece refers to anything that functions by either covering the ear, or hanging near the ear. In this broad category are the parts of an eyeglass frame that extend over the ear, and any material specifically designed to fit into the ear and block off the entry of sound or water. The most common meaning of an “earpiece” however is an electronic device that converts electronic signals into sound waves, and directs them into the ear. In this context, the earpiece can also be called an electronic-acoustic transducer.

Originally, the earpiece was the only way of listening to electronically-generated audio signals. Thereafter, amplifiers were developed, and the role of earpieces became more a matter of personal preference than necessity. Nowadays, earpieces are used for convenience — where privacy is desired, or where mobility is important. Depending on its design, an earpiece can also be variously known as headphones, ear buds, stereo phones or headsets.

what is an earpieceEarpieces can be organized broadly into two categories — wired earpieces and cordless or wireless earpieces. The wireless types use either radio waves or infrared signals to connect to the signal sources. Earpieces for CD players, computers or mobile phones are some examples. A signal transmission link is used, like Bluetooth® or Wi-Fi.

The wired earpiece has to be physically attached to a signal source. To facilitate this, jacks at the end of the cords are inserted into the signal source. Jack sizes have been standardized, and the most common size is the 3.5 millimeter (about 0.2 inches) that was brought into the market by the Sony Company in 1979. The much older, 1/4 inch (about 6.4 mm) jack is now used only in professional equipment. When wiring up the stereo jacks, the tip is always the left channel, the portion in between is the right channel, and the outer sleeve is the ground.

The use of ear buds has a profound impact on how one perceives sound. This is because an earpiece feeds the sound directly into the eardrums, without the normal acoustic contouring by the listener’s head and outer ear that normal loudspeakers give scope for. Lacking these spatial references, the brain then imagines the sound to be in a straight line within the head and between the ears. This strips the sound of its 3 dimensional effect, otherwise produced by the normal loudspeakers.

From their shapes and sizes, earpieces can be placed into four categories. The circum-aural types have large pads that surround the outer ear. They are most commonly used in recording studios. The supra-aural headphones fit just over the ear, without fully surrounding it. Ear buds are designed to fit inside outer ear’s canal. However, they don’t fully cover the canal, and exterior sounds can still be heard around them. In contrast, canal phones, the fourth category, fit snugly into the ear’s canal, and effectively block off the external sounds.

Bill Would Allow Coloradans To Use 1 Earphone Behind The Wheel

Published by:

Cellphone makers have come up with lots of devices that make it easier to drive with both hands on the wheel while using their technology, but in Colorado one common setup for going hands-free is illegal.

Using earphones while driving is illegal in the state, even if only one ear has an earbud in it or the headphones have audio coming out of only one side.

Rep. Jovan Melton, a Democrat who represents Aurora, says that’s a problem.

“I definitely understand and respect that they’re following the letter of the law, but people shouldn’t be punished for trying to drive safely by keeping both hands on the wheel,” he said.

Melton says Denver police has written 172 tickets in the past three years for people wearing earphones or a single earbud.

“It’s important that we clean this piece of the statute up,” he said. “Allow people to drive safely without having to worry about being fined or ticketed or pulled over for wanting to do the right thing.”

This is illegal in the US, and is also illegal here in the UK, it’s not common to see drivers in the UK doing this. But the worrying rise in touchscreens in cars could increase the chances of more accidents.

Melton is carrying a bill that would allow motorists to use one earphone or earbud while driving.

“A lot of the earbuds that you get with your phone will come with two for music listening, but we wanted to make sure that you are only using one earbud so you can still hear emergency vehicles,” he said.

Melton’s bill doesn’t require hands-free devices like earphones when talking on the phone behind the wheel. Melton tried and failed to get such legislature approved last year. But he says he’s not giving up.

“I think if we can get this passed it’s just one more step in that conversation which will hopefully lead to a successful (hands-free) bill next year,” he said.

The one earbud bill has passed in the House of Representatives and it was approved unanimously in a Senate committee on Thursday. It now moves on to the full Senate.

Colorado has several laws currently on the books related to distracted driving:

– It is illegal to text and drive

– If you are under 18, you can’t text or talk on the phone

– You cannot have a TV or computer that shows entertainment, social media or email in a position in the vehicle where the driver can see it.

What Is Audio Surveillance?

Published by:

This was originally posted on this website, credit should go them as this is a important article.

Audio surveillance is the act of listening to third-party conversations and recording them. This technique is frequently used by law enforcement, private detectives and government spy agencies. Most audio surveillance consists of either bugging a room, wearing a wire, tapping a phone or distance listening. Each provides distinct advantages and disadvantages, depending on the situation.

audio surveillanceWiretapping is one of the most common and simple form of audio surveillance. This is preferred because it is highly inconspicuous and allows for two sides of a conversation to be clearly recorded. Small audio devices, commonly called bugs, are attached to the internal circuitry of a telephone to pick up a conversation. A signal is wirelessly transmitted to another device that records the conversation. The drawback of this method is getting access to a subject’s telephone to properly wiretap it.

A room microphone is another audio surveillance technique that often is utilized. This involves planting a wireless microphone in a room to pick up conversations. Disguised room microphones are available to look like pens, clocks, stuffed animals and a variety of other covert forms. This microphone sends a signal to a receiver, just like a wiretap does, and the signal can be directly recorded. The disadvantage here is access to some rooms and getting only one side of a phone conversation if it takes place in that room.

Concealable transmitters known as body wires are well-known devices that have been featured in many television shows and movies. A small microphone and transmitting device are worn under the clothes of a person in order to send a signal back to a receiver and record a conversation. This allows the person wearing the wire to ask questions and get specific details that simply listening to other people’s conversations could not provide. The disadvantage of this method is getting access to the person needed to be recorded and also concealing the microphone in a way that hides it but allows for clear recording.

Long-distance microphones are another covert means of audio surveillance. A parabolic microphone, often called a shotgun microphone because of its long shape, has a powerful ability to pick up conversations up to 300 feet (91.4 m) away. Its main disadvantage is its high sensitivity. It can pick up other noises and cannot function if obstructions, such as trees and automobiles, are between the microphone and the conversation.

Why Are Headphones Becoming More Popular?

Published by:

For once, here’sa simple answer. Headphones are increasing in popularity at the same rate as lightweight devices are. The more devices you purchase, the greater headphones you’ll need.

Headphones are useless with out a device to make use of them with, so it stands to reason that headphones are being bought in conjunction with other acquisitions.

The rise of both Tablet PCs and MP3 players has a lot to complete with this. Socially, the iPod’s impact may be profound. When I was little, anybody over the age of about 16 who was wearing headphones and never jogging looked stupid, they appeared like some sort of impotent man-child caught in a desperate attempt to re-capture lost youth. These bizarre nerdlings always looked odd, they walked around in the peculiar manner, sort of a kangaroo that needed a sh*t.

Today naturally, it’s perfectly usual for a person of any age to own an iPod. Even US President Barack Obama was asked about his iPod whilst over on the campaign trail. So it should come as no surprise that headphone sales are skyrocketing.

Then of course came the increase in online gaming and with it the rise of gaming headphones. It was now possible for gamers to speak internationally via the use of headsets and headphones, they might organize their attack patterns on war games, trash talk one another on sports sims or collaborate with each other on RPG games, the whole world opened up to gamers and, in order to access it, they needed to buy a new set of headphones.

Today, Tablet PCs use headphones, cell phones use headphones, portable gaming devices use headphones, in fact, basically everything uses headphones. When I can’t sleep at night, I listen to music on my headsets in order not to wake my girlfriend, I even wear headphones outside, but you know what? So does everybody else.

Next time you’re out and about, shop around you and see just how many people are listening to something, its not just kids, its not only trendy adults, its everyone.

Headsets inevitably need replacing, which leads inexorably to much more sales. Now that everybody is wearing haedphones, even the uncool are cool, which is weird when you think about it.

How Does a 2 Way Radio Work? (Asked by Neil from Reading)

Published by:

Hi Neil,

Did you get a two way radio set from Santa by any chance? Lol.

Anyway, onto your question…

A two way radio basically is a radio that can send and receive signals. If a radio can both transmit and receive, it is known as a transceiver (see what they did there?) Two or more users can use a transceiver in order to communicate on a shared channel.

Essentially, a two way radio works by receiving radio waves through the air and broadcasting a return signal. The antenna on the radio houses a series of electrons, which dictate the channel being picked up by the user (different groups of electrons will respond to different channels). These electrons translate the radio waves into electrical impulses, which are then fed to a small processor. The processor then converts the impulses into a signal and the radio’s speakers then play that signal. The whole process, amazingly, is pretty much instant.

Two way radios convert sound into radio waves and also convert radio waves into sound. Ergo, I can speak to you, like so:

Chris: “Hi Neil. Can you hear me? Over”

Once I push the PTT (push to talk) button and speak, the vibrations of my voice shake a small membrane inside my radio’s microphone (not a million miles removed from the one that exists in the human ear). My radio’s processor then converts those vibrations into a simple electrical signal. The radio pushes the signal to the antenna, which then pushes it out on the audio channel selected.

The electrons in your antenna become excited (steady on there, fella!) and translate the waves into electrical impulses, which are then ‘decoded’ by the processor and played out via your speakers.

So, you hear this on your radio and you reply.

Neil: “Hey 2wayradionline. Yeah, I can hear you just fine. Thanks for the answer. Over”

Whereupon the entire process takes place all over again.

And so on…

I hope that answers your question. Have fun, 2wayradionline.co.uk!

Martian Homes Could Be Built In Just 24 Hours

Published by:

By the end of this century, it seems highly likely that people will be living on Mars. It sounds utterly mad, until you consider that there were only 66 years between the first powered and sustained Human flight and Neil Armstrong setting foot on the moon…

However, a major problem with this idea (aside from the fact that no Human being has ever actually set foot on the red planet) is the difficulty posed by building habitation in such a hostile and extremely remote environment.

At the moment, even landing an unmanned rover on Mars represents a major scientific achievement, which makes Elon Musk’s plans to build a city there seem especially far fetched and ambitious.

Besides, at current costs, taking one kilogram of material to the moon costs between £61,000 and £122,000. That’s a lot of money, even for bare essentials like building materials and water reserves.

Now, however, one man thinks he may have the answer…

Dr. Behrokh Khoshnevis of the University of Southern California’s Viterbi School of Engineering is working on a groundbreaking new method of building that, if applied to lunar or Martian colonisation, could bring us all that much closer to seeing cities on Mars or the moon in our lifetimes.

Essentially, Dr. Khoshnevis has come up with a way to ‘print’ buildings.

The construction technology, called Contour Crafting, fashions an entire building, layer by layer, according to a predetermined outline. Khoshnevis initially created the technology in order to provide cheap, quick and safe housing for emerging nations, or victims of natural disasters.

It is hoped that such building methods will also lower the demand for wood, thus having a beneficial effect on the rainforests and other areas that are being aggressively deforested for timber.

In addition, the concrete walls built by the Countour Crafter are three times stronger than a brick wall.

Writing for Nasa, Dr. Khoshnevis said, “Automated building technologies will revolutionize the way structures are built on Earth, in dense urban environments, in difficult-to-build and difficult-to-service sites, or in remote and hostile regions of the globe. The technologies under development by our group have the potential to simplify construction logistics, reduce the need for hard physical labor by assigning humans to a strictly supervisory role, eliminate issues relating to human safety and produce intricate, aesthetically refined designs and structures at significantly reduced construction cost”.

Theoretically, these buildings could be described via a computer model and built remotely, using the Martian landscape in lieu of bricks and mortar. The buildings could be ‘printed’ in around 24 hours and would be every bit as strong, (or stronger) than the building you are currently living in.
