Wireless Body Area Network


            Future communication systems are driven by the concept of being connected any-where at any time. This is not limited to even in medical area. Wireless medical communications assisting peoples work and replacing wires in a hospital are the applying wireless communications in medical healthcare. The increasing use of wireless networks and the constant miniaturization of electrical devices has empowered the development of wireless body area networks(WBANs).In these networks various sensors are attached on clothing or on thebody or even implanted under the skin. These devices provide continuous healthmonitoring and real-time feedback to the user or medical personnel. The wire-less nature of the network and the wide variety of sensors offer numerous new,practical and innovative applications to improve healthcare and the quality of life.The sensor measures certain parameters of human body, either externally or internally. Examples include measuring the heartbeat, body temperature or recording a prolonged electrocardiogram (ECG).
Several sensors are placed in clothes, directly on the body or under the skin of a person and measure the temperature, blood pressure, heart rate, ECG, EEG, respiration rate, SpO2 levels etc. Next to sensing devices, the patient has actuators which act as drug delivery systems. The medicine can be delivered on predetermined moments, triggered by an external source or immediately when a sensor notices aproblem. The sensor monitors a sudden drop of glucose, a signal can be sent to the actuator inorder to start the injection of insulin. Consequently, the patients will experiences fewer nuisances from his disease. An example of a medical WBAN used forpatient monitoring.
Wireless Body Area Network
A WBAN can also be used to offer assistance to the disabled. For example, a paraplegic can be equipped with sensors determining the position of the legs or with sensors attached to the nerves. In addition, actuators positioned on the legs can stimulate the muscles. Interaction between the data from the sensors and the actuators makes it possible to restore the ability to move. Another example is aid for the visually impaired. An artificial retina, consisting of a matrix of microsensors, can be implanted into the eye beneath the surface of the retina. Theartificial retina translates the electrical impulses into neurological signals. Another area of application can be found in the domain of public safety where the WBAN can be used by firefighters, policemen or in a military environment. The WBAN monitors for example the level of toxics in the air and warns thefirefighters or soldiers if a life threatening level is detected. The introduction of a WBAN further enables to tune more effectively the training schedules of professional athletes.

Positioning WBANS
The protocols developed for WBANs can span from communication between the sensors on the body to communication from a body node to a data center connected to the internet. Thus communication in WBAN is divided into:
1. Intra body communication
2. Extra body communication
Intra-body and extra- body Communication in WBAN
Intra body communication controls the information handling on the body between the sensors or actuators and personal device. And extra body communication ensures communication between the personal devices and an external net-work . This segmentation is similar to the one defined in where a multi-tiered telemedicine system is presented. Tier 1 encompasses the intra-body communication, tier 2 the extra-body communication between the personal device and the Internet and tier 3 represents the extra-body communication from internet to the medical server. To date development has been mainly focused on building the system architecture and service platform for extra-body communication. Much of these implementations focus on the repackaging of traditional sensors (e.g. ECG, heart rate) with existing wireless devices. They consider a very limited WBAN consisting of only a few sensors that are directly and wirelessly connected to a personal device. Further they use transceivers with a large and large antennas that are not adapted for use on a body.
Positioning of a Wireless Body area Network in the realm of wireless networks
In the figure 4.2, a WBAN is compared with other types of wireless networks, such as Wireless Personal (WPAN), Wireless Local(WLAN), Wireless Metropolitan(WMAN), and Wide area networks(WAN). A WBAN is operated close to human body and its communication range will be restricted to a few meters, with typical values around 1-2 meters. While a WBAN is devoted to interconnection of one persons wearable devices, a WPAN is a network in the environment around the person.
Physical Layer
The characteristics of the physical layer are different for a WBAN compared to a regular sensor network due to the proximity of the human body. Tests with TelosB motes (using the CC2420 transceiver) showed lack of communications between nodes located on the chest and nodes located on the back of the patient . This was accentuated when the transmit power was set to a minimum for energy savings reasons. when a person was sitting on a sofa, no communication was possible between the chest and the ankle. Better results were obtained when the antenna was placed 1 cm above the body. As the devices get smaller and more ubiquitous, a direct connection to the personal device will no longer be possible and more complex network topologies will be needed. The characteristics of the propagation of radio waves in a WBAN and other types of communication are as follows.
RF Communication
There exists several path loss along and inside the human body either using narrowband radio signals orUltra Wide Band (UWB). All of them came to the conclusion that the radio signals experience great losses. Generally in wireless networks, the transmitted power drops off is defined as P = dn (5.1) where d represents the distance between the sender and the receiver and n the coefficient of the path loss. In free space, n has a value of 2. Other kinds of lossesinclude fading of signals due to multi-path propagation. The propagation can be classified according to where it takes place: inside the body or along the body.
The body acts as a communication channel where losses are mainly due to absorption of power in the tissue, which is dissipated as heat. As the tissue is lossy and mostly consists of water, the EM-waves are attenuated considerably before they reach the receiver. In order to determine the amount of power lost due to heat dissipation, a standard measure of how much power is absorbed in tissue is used: the specific absorption rate (SAR). It is concluded that the path loss is very high and that, compared to the free space propagation, an additional 30-35 dB at small distances is noticed. It is argued that considering energy consumption is not enough and that the tissue is sensitive to temperature increase.
Artificial Retina
Artificial retina for blind people
WBANs can also assist blind people. Patients with no vision or limited vision can see at a reasonable level by using retina prosthesis chips implanted within a human eye, as shown in Figure
A WBAN is expected to be a very useful technology with potential to offer a wide range of benefits to patients, medical personnel and society through continuous monitoring and early detection of possible problems. With the current technological evolution, sensors and radios will soon be applied as skin patches. Doing so, the sensors will seamlessly be integrated in a WBAN. Step by step, these evolutions will bring us closer to a fully operational WBAN that acts as an enabler for improving the Quality of Life.

MOBILE WiMAX

              Mobile WiMax is a broadband wireless solution that enables convergence of mobile and fixed broadband networks through a common wide area broadband radio access technology and flexible network architecture. The Mobile WiMax Air Interface adopts Orthogonal Frequency Division Multiple Access (OFDMA) for improved multi-path performance in non line-of-sight environments. Scalable OFDMA (SOFDMA) is introduced in the IEEE 802.16eAmendment to support scalable channel bandwidths from 1.25 to 20 MHz.
The Mobile Technical Group (MTG) in the WiMax Forum is developing the Mobile WiMAX system profiles that will define the mandatory and optional features of the IEEE standard that are necessary to build a Mobile WiMax compliant air interface that can be certified by the WiMAX Forum. The Mobile WiMax System Profile enables mobile systems to be configured based on a common base feature set thus ensuring baseline functionality for terminals and base stations that are fully interoperable. Some elements of the base station profiles are specified as optional to provide additional flexibility for deployment based on specific deployment scenarios that may require different configurations that are either capacity-optimized or coverage-optimized
Introduction of Mobile WiMax
Release-1 Mobile WiMax profiles will cover 5,7, 8.75, and 10 MHz channel bandwidths for licensed worldwide spectrum allocations in the2.3 GHz, 2.5 GHz, and 3.5 GHz frequency bands.
Mobile WiMax systems offer scalability in both radio access technology and network architecture, thus providing a great deal of flexibility in network deployment options and service offerings. Some of the salient features supported by Mobile WiMax are:
•  High Data Rates. The inclusion of MIMO (Multiple Input Multiple Output) antenna techniques along with flexible sub-channelization schemes, Advanced Coding and Modulation all enable the Mobile WiMax technology to support peak DL data rates up to 63Mbps per sector and peak UL data rates up to 28 Mbps per sector in a 10 MHz channel.
•  Quality of Service (QoS). The fundamental premise of the IEEE 802.16 MAC architecture is QoS. It defines Service Flows which can map to Diff Serv code points that enable end-to end IP based QoS. Additionally, sub channelization schemes provide a flexible mechanism for optimal scheduling of space, frequency and time resources over the air interface on a frame by-frame basis.
•  Scalability . Despite an increasingly globalize economy, spectrum resources for wireless broadband worldwide are still quite disparate in its allocations. Mobile WiMax technology therefore, is designed to be able to scale to work in different canalizations from 1.25 to 20 MHz to comply with varied worldwide requirements as efforts proceed to achieve spectrum harmonization in the longer term. This also allows diverse economies to realize the multifaceted benefits of the Mobile WiMax technology for their specific geographic needs such as providing affordable internet access in rural settings versus enhancing the capacity of mobile broadband access in metro and suburban areas.
•  Security. Support for a diverse set of user credentials exists including; SIM/USIM cards, Smart Cards, Digital Certificates, and Username/Password schemes.
Mobility. Mobile WiMax supports optimized handover schemes with latencies less than 50milliseconds to ensure real-time applications such as VoIP perform without service degradation. Flexible key management schemes assure that security is maintained during handover
Physical Layer Description :
WiMax must be able to provide a reliable service over long distances to customers using indoor terminals or PC cards (like today's WLAN cards). These requirements, with limited transmit power to comply with health requirements, will limit the link budget. Sub channeling in uplink and smart antennas at the base station has to overcome these constraints. The WiMax system relies on a new radio physical (PHY) layer and appropriate MAC (Media Access Controller) layer to support all demands driven by the target applications.
The PHY layer modulation is based on OFDMA, in combination with a centralized MAC layer for optimized resource allocation and support of QoS for different types of services(VoIP, real-time and non real-time services, best effort). The OFDMA PHY layer is well adapted to the NLOS propagation environment in the 2 - 11 GHz frequency range.
It is inherently robust when it comes to handling the significant delay spread caused by the typical NLOS reflections. Together with adaptive modulation, which is applied to each subscriber individually according to the radio channel capability, OFDMA can provide a high spectral efficiency of about 3 - 4 bit/s/Hz. However, in contrast to single carrier modulation, the OFDMA signal has an increased peak: average ratio and increased frequency accuracy requirements. Therefore, selection of appropriate power amplifiers and frequency recovery concepts are crucial. WiMax provides flexibility in terms of channelization, carrier frequency, and duplex mode (TDD and FDD) to meet a variety of requirements for available spectrum resources and targeted services.

XBOX 360 System


 Virtual reality (VR) is the creation of a highly interactive computer based multimedia environment in which the user becomes a participant with the computer in what is known as a “synthetic environment.” Virtual reality uses computers to immerse one inside a threedimensional program rather than simulate it in two-dimensions on a monitor. Utilizing the concept of virtual reality, the computer engineer integrates video technology, high resolution image-processing, and sensor technology into the data processor so that a person can enter into and react with three-dimensional spaces generated by computer graphics. The goal computer engineers have is to create an artificial world that feels genuine and will respond to every movement one makes, just as the real world does. Naming discrepancies aside, the concept remains the same - using computer technology to create a simulated, three-dimensional world that a user can manipulate and explore while feeling as if he were in that world. Scientists, theorists and engineers have designed dozens of devices and applications to achieve this goal.
Opinions differ on what exactly constitutes a true VR experience, but in general it should include:
 Three-dimensional images that appear to be life-sized from the perspective of the user
 The ability to track a user's motions, particularly his head and eye movements, and correspondingly adjust the images on the user's display to reflect the change in perspective Virtual realities are a set of emerging electronic technologies, with applications in a wide range of fields. This includes education, training, athletics, industrial design, architecture and landscape architecture, urban planning, space exploration, medicine and rehabilitation, entertainment, and model building and research in many fields of science.
Virtual reality (VR) can be defined as a class of computer-controlled multisensory communication technologies that allow more intuitive interactions with data and involve human senses in new ways. Virtual reality can also be defined as an environment created by the computer in which the user feels present. This technology was devised to enable people to deal with information more easily. Virtual Reality provides a different way to see and experience information, one that is dynamic and immediate. It is also a tool for model building and problem solving. Virtual Reality is potentially a tool for experiential learning.
The virtual world is interactive; it responds to the user’s actions. Virtual Reality is defined as a highly interactive, computer-based multimedia environment in which the user becomes the participant in a computer-generated world. It is the simulation of a real or imagined environment that can be experienced visually in the three dimensions of width, height, and depth and that may additionally provide an interactive experience visually in full real-time motion with sound and possibly with tactile and other forms of feedback. VR incorporates 3D technologies that give a real life illusion. VR creates a simulation of real-life situation. The emergence of augmented reality technology in the form of interactive games has produced a valuable tool for education. One of the emerging strengths of VR is that it enables objects and their behaviour to be more accessible and understandable to the human user.

KINECT
Microsoft Xbox 360 Kinect has revolutionized gaming In that you are able to use your entire body as the controller. Conventional Controllers are not required because the Kinect Sensor picks Up on natural body movements as inputs for the game. Three major components play a part in making the Kinect function as it does; the movement tracking, the speech recognition, and the motorized tilt of the sensor itself. The name “Kinect” is a permutation of two words; Kinetic and Connect. The Kinect was first announced on June 1, 2009 at E3 (Electronic Entertainment Expo) as “Project Natal,” the name stems from one of the key project leader’s hometown named “Natal” in Brazil. The software that makes Kinect function was by and large developed by Rare, a Microsoft subsidiary.
The Kinect Sensor XBOX 360 System
A company based In Israel known as PrimeSense developed the 3D sensing technology. Microsoft purchased the rights to use the technology for their gaming system. In the first 60 days on the market, Microsoft shipped 8 million units to retailers around the globe. The estimated Bill of Materials cost for the Kinect is estimated to be $56, which does not include Research and Development or Marketing costs, merely the cost of the hardware.
Sensing Technology
Behind the scene of PrimeSense's 3D sensing technology there are three main parts that make it work. An infrared laser projector, infrared camera, and the RGB colored camera. The depth projector simply floods the room with IR laser beams creating a depth field that can be seen only by the IR camera. Due to infrared’s insensitivity to ambient light, the Kinect can be played in any lighting conditions. However, because the face recognition system is dependent on the RGB camera along with the depth sensor, light is needed for the Kinect to recognize a calibrated player accurately. The following image shows a generalized concept of how kinect's depth sensing works.
How the sensor sees in 3D
In more detail, the IR depth sensor is a monochrome complimentary metal-oxide-semiconductor (CMOS) camera. This means that it is only sees two colors, in this case black and white which is all that’s needed to create a "depth map" of any room. The IR camera used in the Kinect is VGA resolution (640x480) refreshing at a rate of 30Hz. Each camera pixel has a photodiode connected to it, which receives the IR light beams being bounced off objects in the room. The corresponding voltage level of each photodiode depends on how far the object is from the camera. An object that is closer to the camera appears brighter than an object that is farther away. The voltage produced by the photodiode is directly proportional to the distance the object. Each voltage produced by the photodiode is then amplified and then sent to an image processor for further processing. With this process being updated 30 times per second, you can imagine the Kinect has no problem detecting full-body human movements very accurately considering the player is within recommended distance.
Infrared Beams in the Room
Although the hardware is the basis for creating an image that the processor can interpret, the software behind the Kinect is what makes everything possible. Using statistics, probability, and hours of testing different natural human movements the programmers developed software to track the movements of 20 main joints on a human body. This software is how the Kinect can differentiate a player from say a dog that happens to run in front of the IR projector or different players that are playing a game together. The Kinect has the capabilities of tracking up to six different players at a time, but as of now the software can only track up to two active players.
Infrared beams in the room
One of the main features of the Kinect is that it can recognize you individually. When calibrating yourself with the Kinect, the depth sensing and the color camera work together to develop an accurate digital image of how your face looks. The 8- bit color camera, also VGA resolution, detects and stores the skin tone of the person it is calibrating. The depth sensor helps make the facial recognition more accurately by creating 3-D shape of your face. Storing these images of your face and skin tone color is how the Kinect can recognize you when you step in front of the projected IR beams. As mentioned earlier, for the facial recognition to work accurately there needs to be a certain amount of light. Another added feature of the color camera is it takes videos or snapshots at key moments during game play so you can see how you look while playing.

3D INTERNET

                    Also known as virtual worlds, the 3D Internet is a powerful new way for you to reach consumers, business customers, co-workers, partners, and students. It combines the immediacy of television, the versatile content of the Web, and the relationship-building strengths of social networking sites likeFace book . Yet unlike the passive experience of television, the 3D Internet is inherently interactive and engaging. Virtual worlds provide immersive 3D experiences that replicate (and in some cases exceed) real life..
Introduction of 3D Internet
The success of 3D communities and mapping applications, combined with the falling costs of producing 3D environments, are leading some analysts to predict that a dramatic shift is taking place in the way people see and navigate the Internet.The appeal of 3D worlds to consumers and vendors lies in the level of immersion that the programs offer. 

The experience of interacting with another character in a 3D environment, as opposed to a screen name or a flat image, adds new appeal to the act of socializing on the Internet.
Advertisements in Microsoft's Virtual Earth 3D mapping application are placed as billboards and signs on top of buildings, blending in with the application's urban landscapes.

3D worlds also hold benefits beyond simple social interactions. Companies that specialize in interior design or furniture showrooms, where users want to view entire rooms from a variety of angles and perspectives, will be able to offer customized models through users' homePCs .
Google representatives report that the company Google is preparing a new revolutionary product called Google Goggles, an interactive visor that will present Internet content in three dimensions. Apparently the recent rumors of a Google phone refers to a product that is much more innovative than the recent Apple iPhone.
Google's new three dimensional virtual reality :
nyone putting on "the Googgles" - as the insiders call them - will be immersed in a three dimensional "stereo-vision" virtual reality called 3dLife. 3dLife is a pun referring to the three dimensional nature of the interface, but also a reference to the increasingly popular Second Life virtual reality.
The "home page" of 3dLife is called "the Library", a virtual room with virtual books categorized according to the Dewey system. Each book presents a knowledge resource within 3dLife or on the regular World Wide Web. If you pick the book for Pandia, Google will open the Pandia Web site within the frame of a virtual painting hanging on the wall in the virtual library. However, Google admits that many users may find this too complicated.

Apparently Google is preparing a new revolutionary product called Google Goggles, an interactive visor which will display Internet content in three dimensions.
A 3D mouse lets you move effortlessly in all dimensions. Move the 3D mouse controller cap to zoom, pan and rotate simultaneously. The 3D mouse is a virtual extension of your body - and the ideal way to navigate virtual worlds like Second Life.
The Space Navigator is designed for precise control over 3D objects in virtual worlds. Move, fly and build effortlessly without having to think about keyboard commands, which makes the experience more lifelike.

Controlling your avatar with this 3D mouse is fluid and effortless. Walk or fly spontaneously, with ease. In fly cam mode you just move the cap in all directions to fly over the landscape and through the virtual world
Hands on: Exit Reality:
The idea behind ExitReality is that when browsing the web in the old-n-busted 2D version you're undoubtedly using now, you can hit a button to magically transform the site into a 3D environment that you can walk around in and virtually socialize with other users visiting the same site. This shares many of the same goals as Google's Lively (which, so far, doesn't seem so lively), though ExitReality is admittedly attempting a few other tricks.
Installation is performed via an executable file which places ExitReality shortcuts in Quick Launch and on the desktop, but somehow forgets to add the necessary ExitReality button to Firefox's toolbar . After adding the button manually and repeatedly being told our current version was out of date, we were ready to 3D-ify some websites and see just how much of reality we could leave in two-dimensional dust.


Exit Reality is designed to offer different kinds of 3D environments that center around spacious rooms that users can explore and customize, but it can also turn some sites like Flickr into virtual museums, hanging photos on virtual walls and halls. Strangely, it's treating Ars Technical as an image gallery and presenting it as a malformed 3D gallery .

3D Shopping is the most effective way to shop online. 3DInternet dedicated years of research and development and has developed the worlds' first fully functional, interactive and collaborative shopping mall where online users can use our 3DInternet's Hyper-Reality technology to navigate and immerse themselves in a Virtual Shopping Environment. Unlike real life, you won't get tired running around a mall looking for that perfect gift; you won't have to worry about your kids getting lost in the crowd; and you can finally say goodbye to waiting in long lines to check out.

Back up your PC's files for free with these 3 tools


Regular backups are often the only thing that can save your bacon when a hard drive failure or otherwise catastrophic PC meltdown occurs. If your files go poof, they're gone forever unless you've safely stashed copies elsewhere.
You would ideally have at least two back-ups: one kept at home and one stored off-site—a feat that’s easily done with cloud solutions like Backblaze or CrashPlan. There are also various kinds of back-ups you can do like system images that include your files and an OS backup.
But today we’re going to focus on a trio of free, automated tools to back up just your personal files to an external hard drive or other PC—because that’s really the most critical stuff you want to save. PCs and their operating systems can be replaced, but treasured photos of your kids or accounting documents? Not so much.
For all of these tools we’re going to assume your PC is connected to an external hard drive.

Built-in and dead easy

filehistory
The most obvious choice is to use File History, a tool that comes built-in to Windows 8 and 8.1. File History is very much like Time Machine for the Mac, just without all the space traveler graphics. It saves chronological versions of your Windows libraries (documents, music, pictures, and videos), allowing you to go back in time and retrieve specific versions of a file—a handy feature if you want to retrieve a long-deleted section of a document.
By default, File History backs up your documents every hour, but you can change that under Advanced settings.
To get started with File History in Windows 8.1, connect your external drive, then open the Control Panel by right-clicking the Start button and selecting Control Panel.
Make sure the drop down menu in the upper right corner says View by: Large icons. Then just choose File History in the main Control Panel window.
On the next page, click the button labeled Turn on and you’re good to go. If you need to configure File History, look at the links on the left side of the Control Panel screen to specify folders to exclude, select a specific attached drive, and so on.
The only thing with File History is that it won’t grab anything outside your libraries, such as Outlook data files.

SyncBack Free

profile folder
SyncBack Free
A solid third-party option is the free version of SyncBack from 2BrightSparks. With this desktop app all you do is create a new backup, give it a profile name, decide on the type of back-up you want, choose your source and destination folders, and away you go.SyncBack Free lets you schedule times to run your backups via the built-in Task Scheduler in Windows.

Digging into the command line

If you’re not afraid of getting your hands dirty on the command line then try the Rsync utility via Cygwin, a Linux-style command line for Windows.
Rsync is a do-it-yourself option since you’ll have to decide on the commands you use. But the appeal of Rsync is that it’s been around for years, is very solid, and isn’t subject to radical change. In other words, it’s really boring and does its job—which is exactly what you want in a backup utility.
Truth be told, using Rsync isn’t that hard. In fact, you can get it working with just one line of code. I use Rsync for my own backups with this simple instruction on the Cygwin command line:
rsync -auv “/cygdrive/c/Users/[user folder name]/“ “/cygdrive/d/Rsync”
Basically, what this says is start Rsync, copy my entire user folder but only new files or files that have changed, and don’t erase anything. The last little bits that start with “cygdrive” tell Cygwin and Rsync which drives to copy (my entire user folder) and where to copy it to (Drive D:/).
