Cincinnati State Technical College and Community College

The world is stuffed with very awesome, well written posts. Whenever you find one that catches your eye, you have got to post it, well i do! so with permission of the original writer i’ve posted this to take pleasure in

Cincinnati State Technical and Community College (CSTCC) needed to migrate to a communications system that would support clear coverage over a large area and cost-effectively accommodate multiple talkgroups.

Studying the Needs of Campus Security CSTCC is comprised of three campuses and over 1.3 million square feet. Until recently, the college used an all-analog system, components of which were 15 years old. According to Raymond Mirizzi, Director of Facilities at CSTCC, “We needed to upgrade our whole communications system,” and it was vital that the entire campus be covered with a radio solution that would support very clear, consistent and secure communications.

The three-part campus needed a supervisory channel that would provide the flexibility for critical security officers and related personnel to communicate during times of crisis. Of course, because such emergencies can arise at any time, it was also critically important that the migration from analog to digital proceed smoothly and quickly because even brief downtime could put the campus at risk.

A budget had been established, and CSTCC expected a lot of value for their investment. An Educated Customer Makes the Right Choice A consultant was sent to work with CSTCC to determine needs, assess the options, and help them make the right choices. Because MOTOTRBO is still a relatively new solution, it was also important to provide CSTCC with a hands-on demonstration so they could get a sense of the potential that MOTOTRBO could offer.

After the demonstration, CSTCC was so excited about the product that they asked for a quote immediately so they could present it to their trustees that evening. With the recent tragedy at Virginia Tech, trustees were very eager to implement a more secure communications system. The trustees appreciated that security is built into this digital solution: when users monitor digital
Communications, they hear only that the channel is in use – they don’t hear the actual conversation.

“MOTOTRBO was our choice,” explains Michael Wylie, Director of Environment and Public Safety at CSTCC. According to Wylie, based on the demonstration it was obvious that “MOTOTRBO electronics were much better and reception was much clearer than what we had in our old analog system.” Wylie was working under a budget, and MOTOTRBO supports lower cost of ownership compared to analog systems because fewer repeaters are required: two voice channels are utilized in one 12.5kHz frequency channel, so only one repeater is needed for every two voice or data paths. Considering all factors, Wylie concluded that “we could replace our old system with this higher quality solution at a reasonable cost.” MOTOTRBO also proved to be a way to ensure a smooth migration from analog to digital, supporting dual mode operations that could enable backwards communication between new units and older units already in place. Following this migration strategy, CSTCC could buy a few MOTOTRBO radios and use them in the analog mode; as time and budget allowed, they could then start migrating a few radios at a time to digital.

Graduating to a Better Communications Solution Mirizzi understands that “when you’re going offline to restart a new system, there will be a down period, and that can be a big problem if there’s an mergency taking place. When we switched to MOTOTRBO, however, most people on campus didn’t even know we switched over. It was that smooth.” MOTOTRBO is now installed at CSTCC with 16 channels, one of which is to be used exclusively by supervisory personnel. According to Wylie,
“This afforded us the opportunity to carry on confidential conversations without everyone else hearing what was going on.” Having this supervisory channel would mean that CSTCC didn’t have to buy an extra FCC license or a new conventional repeater.

The security repeater has ten units running off it; the facilities repeater has forty units running off it
and each one can be expanded to several hundred users, so there’s plenty of room to grow.

MOTOTRBO also provides much clearer audio quality than is possible with analog, especially in fringe
coverage areas – and that’s especially important on this sprawling campus. A digital signal is inherently clearer than analog; and with noise suppression technology, MOTOTRBO audio becomes even crisper and sharper. “MOTOTRBO gave us the ability,” Mirizzi says, “to communicate at a greater distance and branch out and create different channels for our internal operations. And then we had the opportunity for facilities and security to come together and communicate as one group, bringing together the right people at the right time.”

MOTOTRBO – Ready to Grow, Digitally Designed to facilitate quick and easy migration and operate in mixed analog and digital environments, MOTOTRBO’s digital technology can be adapted to a number of different work environments, seamlessly supporting industry-specific applications. The open, flexible and licensable data interface offered by MOTOTRBO is designed to be regularly enhanced
through 3rd party devices and applications, making MOTOTRBO a terrifically expandable platform that gives users the opportunity to upgrade their radios as needed for continuously higher performance.MOTOTRBO is a complete system of mobile and portable units, repeater, data applications and accessories that can be easily adapted meet specific customer needs, whether in education, service or industrial environments. A forward-compatible platform, MOTOTRBO provides a solid foundation for future growth of a communications system.

The Oculus Rift: virtual reality is no longer a joke

You’ve probably stumbled upon this looking for information about headphone’s, hopefully this will help you answer some of those questions, if not please click on one of the relevant links within the article

The decades most exciting development in computer hardware looks a little like a fat black envelope stuck to a pair of ski goggles, and I had one strapped to my face two months ago as I sat at a desk in the Earls Court Exhibition Centre preparing to fly a Spitfire under a bridge.

Headphones over my ears replaced the thumping bass of the surrounding trade show with the spluttery growl of a Merlin engine. Looking down, I saw a pair of khakied knees and a gloved hand gripping a control yoke; above and to either side, the sun glittered through the cockpit canopy. As I flipped the aircraft into a turn and dive, my senses insisted that I was soaring, upside down, under an iron bridge and into a canyon. But my body and brain remained obstinately upright in a chair in west London, at the glorious mercy of a technology that promises to bring back that most laughable of Nineties computing obsessions: virtual reality.

This device is called the Oculus Rift, and it has come a long way since 2011, when Palmer Luckey, a 19-year-old Californian student, built the prototype from scavenged parts in his parents garage. Luckey was an enthusiastic collector of old VR hardware the clunky headsets that had enjoyed a brief tenure in Nineties amusement arcades and had long dreamt of bringing back the technology in a useful form.

But despite the colourful cyber-predictions of films such as Lawnmower Man, there were good reasons that the virtual reality craze had fizzled out by the millennium. The headsets were too heavy to wear for long, and immersion in the blocky graphics of these early virtual worlds came at a price: a stiff neck, motion sickness and the feeling of wading through treacle.

By 2011, however, the magic combination of accurate motion-sensing with lightweight, high-resolution displays no longer seemed so far off. As Luckey realised, the technology was by then integrated into most decent smartphones. So his prototype Rift used the equivalent of a large smartphone screen to display offset moving images, one for each eye, which the brain combined into an illusion of 3D depth. Head movements were tracked with phone-equivalent gyroscopes and accelerometers, adjusting the view so the user could look freely around a 3D world.

Two years on, Luckeys company Oculus VR is still piggybacking on vicious competition in the smartphone market, as its product lead Joseph Chen freely acknowledges.

Those guys are tearing each other apart trying to get the next best thing, he says. That has basically driven the costs down to where theyre affordable: displays and sensors that used to be hundreds of dollars now cost pennies. Oculus charges just $300 (180) for a low resolution developer kit a kit for companies interested in developing software for the device and has shipped more than 40,000 worldwide, the biggest deployment of virtual reality headsets in history. It has raised $91million (55.5 million) in investment funding and done this without actually having a product on the market: you cant buy it in shops until next year.

The excitement surrounding the Oculus was palpable at the Eurogamer Expo, the games show where I tried out its second-generation prototype. This is understandable: to many enthusiasts, the prospect of stepping wholesale into a virtual fantasy world fulfils one of the oldest promises of the medium.

An example of the view using an Oculus Rift

But theres more to this technology than gaming. Among the demonstrations Chen showed me was a London tourism experience, built from 360-degree camera views of locations in the capital by the media agency Visualise. The viewer begins perched on top of the London Eye wheel, staring out over the capital, and can beam into various 3D-modelled locations across town London Zoo, the Gherkin, Piccadilly Circus by a shift of visual focus.

Another demonstration by Arch Virtual, a business that creates 3D software for a wide range of clients, offered a virtual tour of an architects concept house. Using a controller, I was able to walk wherever I liked in the building. The sense of inhabiting real space in these demonstrations was astonishing.

Jon Brouchoud, the Wisconsin-based architect who runs Arch Virtual, says that using the Rift developer kit transformed the way he designs. Any time youre looking at an architectural illustration projected onto a screen its distorted, he tells me. Theres a natural distortion based on the way 3D maps onto a 2D surface. Put the same environment in the Oculus Rift and its completely different. Being able to stand inside a space, go back to the drawing board and then stand inside it again completely changes the way you design a building. If this isnt the game-changer for architecture, I dont know what is.

Arch Virtual, Brouchoud says, has also taken on several secret projects for medical clients. VR technology has already been used to aid neurological recovery from trauma, as well as to treat conditions such as post-traumatic stress disorder, post-stroke rehabilitation and phantom limb syndrome.

Andrew Poulter, an expert in computer science and simulation at the MoDs Defence Science and Technology Laboratory, envisages still other applications for the technology hinted at by the Rift. In the past two years the US army has spent $57million (35million) on an immersive training simulator called the Dismounted Soldier Training System, which tracks not just head movement but limb positioning and weapon movements.

In Britain, Poulter explains, head-mounted VR technology is still only being used experimentally, within a research context, although his lab has been looking closely at developer versions of the Rift.

A good deal of British military training, Poulter explains, is still done with on-screen computer programs. But the Oculus Rift, he says, represents a new class of hardware with real potential. And it is games technology that now sets the trend for the defence industry, not the other way around. The defence budgets of even the largest countries are relatively small compared to the massive budgets that the entertainment industry has.

Its easy to forget that none of this technology is really available yet. Oculus is shipping only to developers with the technical know-how to plumb the depths of the software, while many of its prospective rivals remain shrouded in mystery. A few weeks ago, Sony filed a patent related to a head-mounted display, seeming to lend credence to rumours that it plans to launch a VR headset in 2014 for the PlayStation 4.

But the competition is certainly gathering. A device called the CastAR, which overlays 3D images onto a real-world view, recently completed a successful run on the crowdfunding site Kickstarter and has entered production. On the morning that I sat down to write this piece, news broke that another Oculus rival, the gloriously sci-fi sounding Avegant Glyph, will take to Kickstarter in January: it promises to project 3D images onto the human retina and fold up into a pair of headphones when youre done with it.

The team at Oculus, meanwhile, promises a further revolution in display technology when it exhibits a new prototype at the Consumer Electronics Show in January, and says it will have goggles in the hands of consumers by the end of the year. Looking forward into this immersive future, one is tempted to agree with the 90-year-old lady whose experience with the Oculus Rift has attracted more than two million viewers on YouTube.

This is something else, she exclaims raptly, clutching the visor to her face with both hands. Am I still sitting where I was? Holy mackerel!
