...management control system case analysis solution and analysis Analog Devices, Incorporated: Microelectromechanical Systems (MEMS) From a conference room on the top floor of the four-story semiconductor manufacturing facility, Ray Stata briefly took in the view of the Massachusetts Institute of Technology (MIT) campus. In particular, he noticed the building under construction that would soon bear his name. Asked how this particular honor felt, Mr. Stata responded with a humble shrug. However, when asked about the Microelectromechanical Systems (MEMS) business, Mr. Stata was willing to show considerable pride. Mr. Stata was Chairman of Analog Devices, Incorporated (ADI), a company which he co-founded in 1965. MEMS was one division. He had invested a tremendous amount of personal attention and energy to the success of MEMS – and risked his reputation. In fact, without his vision and dedicated leadership, this ambitious, entrepreneurial effort would have collapsed under mounting losses several years earlier. During one three-year stretch, from 1997 to 2000, Mr. Stata had decided to simultaneously serve as Chairman of ADI and General Manager of the MEMS division in order to keep the venture alive. In 2002, Mr. Stata regarded the MEMS business as a jewel. With worldwide technical supremacy that had been built over fifteen years, the business was profitable, and the long-term growth prospects appeared tremendous. Still, he readily acknowledged that many...

...1. Why did Google make this move? What do they hope to accomplish? Congress had mandated the airwaves in the 700MHz band be vacated in February 2009, forcing analog TV broadcasters off those channels as part of a long-anticipated switch to all-digital television. The bid done four years ago offered free wireless broadband access using that spectrum with inherent physical properties, which allow signals to travel farther and more easily penetrate walls, and Comcast and Verizon claiming that it was “unfair competition” and that cities would be violating their commitments to offer local monopolies to these companies opposed it. While Google's entrance was likely to turn the wireless world upside-down, market disruption is not its motivation. Google's priority as a public company is to make a profit; having a Google-branded wireless service would attract a good deal more eyeballs to its ad-based services. And mobile, in some ways, is particularly fruitful for advertising. Owning the spectrum would gave Google an advantage in local advertising, which is tailor-made for mobile use as people look for nearby restaurants, gas stations, or copy shops, and would also gave Google a boost in international markets. Google has managed to turn Web search into a billionaire business on PCs by selling simple text ads that appear with search results. Imagine how lucrative that market will be when the ads, including local advertising, can get to the far reaches of the world where there aren't...

...How Computer Fraud and Abuse Evolved Before 1984 there was little that could be done about computer fraud. In 1984 the Counterfeit Access Device and Computer Fraud and Abuse Act was the first legislation on computer fraud. The act made it a misdemeanor to illegally retrieve financial and credit information by computer. Also, the act made it illegal to cause harm to other computer systems. Around this time, what constitutes computer crime was still an ongoing discussion. As a Federal Act, only half of the states passed similar statues. (History of Computer Crime) The Computer Fraud and Abuse Act can be violated in two ways, either by an outsider trespasses into a computer or by someone on the inside who exceed their given authorization and go beyond their standard expectation. The first person who was charged for violating the Computer Fraud and Abuse Act was Robert T. Morris Jr. He caused harm to many universities and government computers by releasing a worm and was the creator of the first computer virus. He argued that he had only just exceeded his authorized access and not accessed the computers without authorization. To exceed authorization defined by the Computer Fraud and Abuse Act as “to access a computer with authorization and to use such access to obtain or alter information in the computer that the accesser is not entitled so to obtain or alter." The court found Morris guilty of acting without authorization. (Computer Fraud and Abuse Act (CFAA)) As the internet...

Future Work-------------------------------------------------------------(7) References----------------------------------------------------------------(8) Appendix A--------------------------------------------------------------(9) Appendix B--------------------------------------------------------------(10) Abstract We introduce one method of addressing the problem of finding the Revolutions per minute of a DC motor without the use of a commercial tachometer, through the use of Dragon Board-12 embedded system. The method we chose to use involved setting up a low pass filter circuit to reduce noise and voltage to a level that the safe for use with the Dragon Board-12. The output from the low-pass filter was then passed through an analog to digital converter which was coded using C code, to convert the signal into a machine readable input. The input was then converted into revolutions per minute and then stored for 15ms, at which time an average was taken (to reduce noise) and then sent to the LCD screen as the tachometer output in revolutions per minute. Introduction In modern days, with the increased usage of Dragon 12-plus USB trainer in universities, more and more applications have been created on the board. The Dragon 12-plus USB trainer is a low cost, featured-packed training board for the new Freescale HCS12 microcontroller family. The board is compatible with the Freescale 9S12DP256EVB board and other similar development boards on the market today, but it also...

...Demo 2 Patient Monitoring System Through Internet Patient Monitoring System through Internet is system used to track off the patient’s health statue. For example some this system will inform the doctor with patient’s heart’s pumping rate, blood’s pressure rate, and many other necessary things. Each activity in the body have different signal in this system so the doctor can differentiate each activity for what it belongs for. For instance if the activity was for brain’s signals it will be (ECG), for the heart (EEG), and for muscles (EMG). These signals called biological signals and made as a form of electrical signals. Bioelectrical signals show various biological activities. This system needs electrodes to extract signals from the body. This system works by attaching devices on special places on the patient body and each part in the body represents a special kind of signals. This system has several parts and one of these parts is Isolation Amplifier. Isolation Amplifier is made to transfer signals to system but also it’s a main reason for patient’s safety because it prevents signals from going back. Imagine that these amplifiers don’t prevent signals from going back. What would happen? Simply the system will cause the patient and electric shock. The second part is called Bio-potential amplifier, which it acts on bioelectric signals. Signal from patient is gone to increase level of signal by the bio-potential amplifier. All the amplifiers are made to recommend the...

...book is concerned with the transmission of information by electrical means using digital communication techniques. Information may be transmitted from one point to another using either digital or analog communication systems. In a digital communication system, the information is processed so that it can be represented by a sequence of discrete messages as shown in Figure 1–1. The digital source in Figure 1–1 may be the result of sampling and quantizing an analog source such as speech, or it may represent a naturally digital source such as an electronic mail file. In either case, each message is one of a finite set containing q messages. If q = 2, the source is referred to as a binary source, and the two possible digit values are called bits, a contraction for binary digits. Note also that source outputs, whether discrete or analog, are inherently random. If they were not, there would be no need for a communication system. For example, expanding on the case where the digital information results from an analog source, consider a sensor whose output voltage at any given time instant may assume a continuum of values. This waveform may be processed by sampling at appropriately spaced time instants, quantizing these samples, and converting each quantized sample to a binary number (i.e., an analog-to-digital converter). Each sample value is therefore represented by a sequence of 1s and 0s, and the communication system associates the message 1 with a transmitted signal s1(t) and the message...

...Eagle Scout Ambitions When I first found out I had to write a paper about my life ambitions and purpose, I thought of everything, then I scrambled through my mind to find the answer. This is what I believe; I have been striving for many years at. I’ll give the background first, and then elaborate. Computers, tech, and math seemed to always be my strong points. I first learned what a CIO (Chief Information Officer) was in a parking lot in front of a law firm while talking to my dad about what all the big C’s, you could say, are in business. I instantly knew that was what I wanted to be. I started out playing computer games like most kids that are growing up in the new tech era. That’s where I had to deal with problems that I faced and adapted to and eventually learned more about. My first computer was a Mac Book, a gift from my mom, which made my life easier. I had everything on it. I had friends that always had problems with computers, and that what gave me more knowledge. If didn’t know the answer to a problem, I never gave up till I got it right. Gaming as I can now see almost ruined my childhood. I didn’t get out much, which made me get overweight. However, what I can say about all those hours on the computer is that it made me type amazingly fast, and it gave me the inspiration to build my own computer in the 7th grade. It increased my vocabulary in a way, and it always made me strive to learn more. I learned Python Programming in the 7th grade and, like...

...| Analog and Digital Comparison | NTC/362 Fundamentals in Networking | EDWARD BROWN | Jose Giralt | 3/18/2013 | | A signal is simply the transmission of data from one place to another place. In our day to day life we deal with various signals constantly like signals from music, power lines, telephones, and cellular devices. Analog and digital are two kinds of signals which are used for the transmission of information from source to destination. Usually the information to be transmitted from one place to another is either audio or video. This information signal is then transformed into those signals which can be transmitted via different channels. For the analog format, the data is transformed into electrical pulses with varying amplitude while for the digital format; the data is transformed into binary format representing two amplitudes. We have various such equipment like analog or digital phones, fax machines, modems, clocks, watches etc. Analog technology is the older one and has been used for decades. It is cheap too but the problem with analog signals is that there is a limitation on the size of the data that can be transmitted at any given point of time. With the advent of digital technology many improvements and new techniques have been introduced. Now days almost every appliance or equipment is based on digital technology. In this, the transmitter translate the data into binary form and the receiver re assemble and produces the...

...The History of Computer Games Origins Computer Games originated in the late 1940’s using only the technology people had at hand at that time, such as primitive interactive electronic devices along with various display formats. The first Computer game device was created in 1947 by Thomas Goldsmith and Estle Ray Mann and patented in 1948; they called the device the “Cathode Ray Tube Amusement device”. Goldsmith and Mann’s design was based on the standard military radar display units, their machine allowed the user to control a vector drawn dot on the screen via an analogue device which simulated missiles being fired at different targets which were simply drawings stuck on to the screen. Another early example of a computer game was called the Nimrod. The Nimrod was the world’s first digital computer constructed specifically to play a computer game; this specially designed computer played the game Nim. The device was designed and built by the company Ferranti, a major UK electrical engineering and equipment firm, known primarily for defence electronics and power grid systems. The Nimrod was first seen during the 1951 Festival of Britain when it was displayed at the exhibition of science, the festivals purpose was to promote better quality design in the rebuilding of Britain following the aftermath of the Second World War. Shortly after the Nimrod was displayed at the 1951 Festival of Britain, in 1952 Dr Alexander Douglas released the noughts and crosses computer game OXO...

...A computer is an electronic machine which helps solving problems quickly and easily.It solves problems according to instructions given to it by the computer user. - The first computer was invented in the US in 1969 at the Rowayton Library in Norwalk, CT Invention Nobody knows who built the first computer. This is because the word "computer" used to mean a person who did maths as their job (a human computer). Because of this, some people say that humans were the first computers. Human computers got bored doing the same maths over and over again, and made tools (mostly mechanical calculating devices like abacuses) to help them get the answers to their problems. It is said that the inventor of the 'modern' computer was Charles Babbage. Automation Humans have a problem with maths. To show this, try doing 584 x 3,220 in your head. It is hard to remember all the steps! People made tools to help them remember where they were in a maths problem. The other problem people have is that they have to do the same problem over and over and over again. A cashier used to make change every day in her head or with a piece of paper. That took a lot of time and people made mistakes. So people made machines that did those same things over and over. This part of computer history is called the "history of automated calculation," which is a fancy phrase for "the history of machines that make it easy for me to do this same maths problem over and over without making mistakes." The abacus...
