Introduction:
Kinect is a mainly a motion sensing input device. In this project it is used to enable control and interact with the application without the need to touch the object, through a natural user interface and using gesture and spoken commands may be.
The Microsoft Kinect consists of an infrared projector, a color camera, an infrared sensor and Multi-array microphone that enables to: 1) Acoustic source localization 2) Ambient noise suppression

Camera characteristics (1):
The depth sensor captures video data in 3D under any ambient light conditions: 1) Infrared laser projector 2) Monochrome CMOS sensor
Different depth measurement techniques are there.
Here is a brief discussion about each of them:
Lets first talk about the stereo triangulation method:
(A stereo camera system can be used for determining the depth to points in the scene. Now first have to know what stereo camera is and what the features are. (A stereo camera is a type of camera with two or more lenses with a separate image sensor or film frame for each lens. This allows the camera to simulate humanbinocular vision, and therefore gives it the ability to capture three-dimensional images, a process known as stereo photography. Stereo cameras may be used for making stereoviews and 3D pictures for movies, or for range imaging. The distance between the lenses in a typical stereo camera (the intra-axial distance) is about the distance between one's eyes (known as the intra-ocular distance) and is about 6.35 cm, though a longer base line (greater inter-camera distance) produces more extreme 3-dimensionality). This is the clarification of stereo camera.From the center point of the line between their focal points. In order to solve the depth measurement problem using a stereo camera system it is necessary to first find corresponding points in the different images. Solving the correspondence problem is one of the main problems when using this type of technique. For instance, it is difficult to solve the correspondence problem for image points that lie inside regions of homogeneous intensity or color. As a consequence, range imaging based on stereo triangulation can usually produce reliable depth estimates only for a subset of all points visible in the multiple cameras.
The advantage of this technique is that the measurement is more or less passive; it does not require special conditions in terms of scene illumination. The other techniques mentioned here do not have to solve the correspondence problem but are instead dependent on particular scene illumination conditions.)

Disadvantages: • At least two calibrated cameras required • Multiple computationally expensive steps • Dependence on scene illumination • Dependence on surface texturing

Time-of-Flight (ToF)
•Perform the depth quantifying the changes that an emitted light signal encounters when it bounces back from objects in a scene

Time-of-Flight (ToF)
Advantages:
•Only one camera required
•Acquisition of 3D scene geometry in real-time
•Reduced dependence on scene illumination
•Almost no dependence on surface texturing

Principles of ToF Imaging: Pulsed Modulation (1)
•Measure distance to a 3D object by measuring the absolute time a light pulse needs to travel from a source into the 3D scene and back, after reflection:
–Speed of light is constant and known: c = 3·10^8 m/s

Principles of ToF Imaging: Pulsed Modulation (2)
•Advantages:
–Direct measurement of time-of-flight
–High-energy light pulses limit influence of background illumunation
•Disadvantages:
–High-accuracy time measurement required
–Measurement of light pulse return is inexact, due to light scattering
–Difficulty to generate short light pulses with fast rise and fall times
Principles of ToF Imaging: Continuous Wave Modulation (1)
•Continuous light waves instead of short light pulses
•Modulation in terms of frequency of sinusoidal waves
•Detected wave after reflection has shifted phase
•Phase shift proportional to distance from reflecting surface

Principles of ToF Imaging: Continuous Wave Modulation (2)
•Retrieve phase shift by demodulation of received signal
•Demodulation by cross-correlation of received signal with emitted signal
•Emitted sinusoidal signal:
•Received signal after reflection from 3D surface:
•Cross-correlation of both signals:

: modulation frequency b: constant bias a: amplitude
: phase shift
:offset

Rondell Data Corp Case Study

...Forbus threw the stack of prints and specifications down on his desk in disgust. The Model 802 wide-band modulator, released for production the previous Thursday, had just come back to Frank's Engineering Services Department with a caustic note that began, "This one can't be produced, either. . . ." It was the fourth time Production had kicked the design back. Frank Forbus, director of engineering for Rondell Data Corp., was normally a quiet man. But the Model 802 was stretching his patience; it was beginning to look just like other new products that had hit delays and problems in the transition from design to production during the eight months Frank had worked for Rondell. These problems were nothing new at the sprawling old Rondell factory; Frank's predecessor in the engineering job had run afoul of them too, and had finally been fired for protesting too vehemently about the other departments. But the Model 802 should have been different. Frank had met two months before (July 3, 2004) with the firm's president, Bill Hunt, and with factory superintendent Dave Schwab to smooth the way for the new modulator design. He thought back to the meeting. . . . "Now we all know there's a tight deadline on the 802," Bill Hunt said, "and Frank's done well to ask us to talk about its introduction. I'm counting on both of you to find any snags in the system, and to work together to get that first production run out by October second. Can you do it?" ...

But then it doesn’t mean that Daniel shouldn’t need to see Hambali personally to discuss the matter in fact it is a must, because of Daniel has to act professional he need to do it step by step. This is also Daniel’s duty as a engineer where he needs to tell the truth as mentioned by Immanuel Kant that duties are absolute and unconditional.. Should Daniel have a conversation with Hambali about his concerns? If so, what type of conversation should Daniel have with Hambali when he talks with him? In my opinion Daniel should have a conversation with Hambali about his concerns and Daniel should have a formal conversation with hambali because what he is done is against the codes of ethics of an engineer that is being honest and impartial and serving with fidelity the public their employers and clients. Then he need to explained all the ethics and fundamental canons of being an engineer because engineer serve for the society we all need to behave. Other than that by having a conversation with Hambali it will make he realize that practice the engineering ethics is very important and when Hambali admits his mistake he will get a lesson from it and slightly if not much improve his ethical judgement ...

Engineering Discourse Community

...communities. In a discourse community, the communication between its members is vital because it causes them to have shared knowledge and similar interests. Due to the different communities having distinct interests, the way they converse can be altered to best suit each group. For example, a group of doctors would talk about medical subjects unlike sport fans would talk about a sport. I am a mechanical engineering student and therefore identify with the engineering discourse community. In this field, the community use different platforms of communication to reach its members. The internet is an effective way of communicating with engineers and the website Engineering.com is a useful resource to share information. Engineering.com is a site used by engineering professionals or companies to communicate ideas and information with other people in the engineering community. I came across this website while searching for engineering websites on the internet. I would expect other people to find this site by the same means I did. What drew me into the site was what was said in the ‘About Us’ section. The site prides itself on bringing, “…the most influential voices in engineering to a worldwide audience of engineers.” This statement help make the site more professional and credible because it is telling the users that not just anyone can put information on the site and that the contents are created by people who know what they are talking about.

Engineering Technology: Revolutionized

...beginning will change everything down to a distinct thought. History has proven that the steps forward in technology within engineering have grown larger and are concluded at a more rapid rate and within the last twenty years. Such a large amount has improved so rapid as cities grow and technology advances, engineering is moving along with the tide. Engineers that grow and see their world of work improve every day because of certain advances in technology all depending on their field. This how engineering features evolved into what they are today from within the last two decades; and how the change will continue to advance as modern Technology embraces a post-modern era. Engineering has existed since the earliest times of culture and perhaps is one of the older lines of labor on earth (the earliest invention of engineering goes back as early as the invention of the wheel). It’s extraordinary that we came so far since the discovery of the wheel. The technology that has been accomplished today just engulfs the minds of people. Everyday modern technology is taken over the minds of people and they continue to adapt to the modern changes within the ever changing society. Through centuries there are trails left by ancient engineering and has differed from our technology today. Through the ancient era there has been astounding and un-answering feats of engineering. Like the great pyramids of Egypt and the great coliseums of Rome. They manufactured these man-made objects so big with no...

The Moral Status of Loyalty

...going to be a problem or issue for engineers. Being loyal to your beliefs, the company you work for, and society is always going to come as a challenge because you really cannot make everyone happy all of the time. Baron states, “The NSPE Code begins, ‘The Engineer, to uphold and advance the honor and dignity of the engineering profession and in keeping with the high standards of ethical conduct. . . will be honest and impartial, and will serve with devotion his employer, his clients, and the public. . . .’ Can an engineer, no matter how heroic, always serve each of these parties with devotion? Can he or she, in other words, always be loyal to all three? The answer is clearly, ‘No.’“ (Baron 22) Baron says that the answer to this question is clearly “No.” She follows this by giving two conditional examples, the B.F. Goodrich and Ford Pinto engineers, which are very one-sided in agreement to her claim. She believes that you cannot be loyal to everyone all of the time, but when every situation is dissected, her view becomes questionable. Every situation is different, and sometimes it may be difficult to be loyal to all three, but it can definitely be done. If we talk about the youtube video of whistle blowing, Baron considers “blowing the whistle” as...

Oprah

...Jamont Waters Macroeconomics November 5, 2012 Oprah Winfrey Most Successful Talk Show Host to Live Oprah Winfrey is the most successful talk show host that has ever graced this earth. Oprah was born in a poor rural town of Kosciusko, Mississippi on January 25, 1954. After a troubled childhood filled with sexual abuse by a number of male relatives and friends of her mother, Vernita, Oprah moved to Nashville to live with her father, Vernon, a barber and businessman. She went to Tennessee State University in 1971 and began working in radio and television broadcasting in Nashville. In 1976, Oprah moved to Baltimore where she hosted the TV chat show, People Are Talking. The show became a hit and Oprah stayed with it for eight years. She then hosted her own morning show A.M. Chicago after she was recruited by a Chicago TV station. At this time Donahue was competition for her, but within several months of her A.M. show, she had won her 100,000 more viewers than Donahue and had taken her show from last place to first in the ratings. Her success led to nationwide fame and a role in the film, The Color Purple, in 1985. She was nominated for an Academy Award for Best Supporting Actress. Oprah launched the Oprah Winfrey Show in 1986 as a nationally syndicated program. Her show grossed over $125 million by the end of its first year, which Oprah received $30 million. She was on 120 channels and had an audience of 10 million people. She soon gained ownership of the program from ABC, drawing...

Ah Ha Moment

...of our 25 more months in this program as well as when we are clinical CRNAs and working as a professional in this field. I think one of my first big “ah ahh” moments came to me during the wellness lecture by Janet DeWan. I struggled in the beginning of the semester with getting back into the mode of studying daily and keeping up with reading and school work as I had been removed from the full time school load for two years during my time as an ICU nurse. I was exhausted and struggling to keep up with my daily reading and studying for multiple very intense courses in this program. I thought I was the only one who was struggling and becoming overwhelmed. I wasn’t alone, and I learned that in talking with my classmates. I was able to talk to them about their own personal struggles and stresses that they were facing with this program as well and we became a support system for each other. Janet Dewan then talked to us about the stresses we face as SRNAs and later in life as CRNAs and the importance of finding our own coping mechanisms for that stress so that we do not lose sight of our focus and desire to become successful CRNAs. Many SRNAs and CRNA’s fall victim to substance abuse or mental breakdowns because of the stresses they are coping with because they do not know how to channel their stress and keep their lives and studies on track. I realized that I need to have an outlet of stress relief for me personally that is healthy, mentally and...

She has become a demi-god in America. There are people who are ready to worship the ground over which she walks. She has lived the Great American dream, a veritable tale of rags to riches with the right amount of glamor added to it. Born in 1954 to unmarried parents, Oprah was raised by her grandmother on a farm with no indoor plumbing in Kosciusko, Mississippi. Oprah's childhood turned into a nightmare because of sexual abuse that she suffered. After suffering abuse and molestation, she ran away and was sent to a juvenile detention home at the age of 13. In 1968, at the age of 14 she gave birth to a premature baby who died soon after birth. An incident of this nature can devastate the entire life of a person. But Oprah Winfrey came out of it a stronger and fiercely determined individual. Her story is one of unrelenting focus and determination. Oprah's tryst with the world of entertainment began when at the age of three she began speaking in church. By the time she was a teenager Oprah was touring the churches of Nashville, reciting the sermons of James Weldon Johnson. Crowned Miss Fire Prevention in Nashville at 17, Winfrey visited a local radio station, where she was invited to read copy. She was so good that she was...
