...DEVELOPMENT OF LCD COMPUTER MONITOR TRAINER LUIS D. DULNUAN JR. TECHNOLOGICAL UNIVERSITY OF THE PHILIPPINES CAVITE CAMPUS 1 INTRODUCTION The idea behind the development of an LCD Computer Monitor Trainer is to have an instructional material in teaching troubleshooting skills and repair of LCD monitors. Compared to a conventional LCD monitors, the trainer provides easy access to the different parts of the monitor particularly the printed circuits boards (PCB). To prevent accidental short-circuits and for safety purposes, test points were provided where voltages can be measured using a voltmeter or oscilloscope, without going to the printed circuit boards. In addition, simulation switches were also included in the design to simulate the common faults that may occur in a Liquid Crystal Display monitor. Simulation of faults is essential when doing laboratory experiments on the trainer, which conventional LCD monitors cannot provide. The trainer is also accompanied by a service manual and laboratory manual that will guide the instructor and students in the proper use of the instructional device. This study is relevant and timely owing to the popularity of LCD computer monitors nowadays and the absence of instructional/training devices in teaching skills in troubleshooting LCD monitors. This project is primarily developed to be used by the following: the instructors in computer teaching LCD monitor servicing; the instructors in electronics dealing with troubleshooting and...

...Currently Riordan Manufacturing has several different offices and each office is using a different type of system, but there is not a central system that monitors each of the satellite offices and their production. To assist Riordan become more efficient, they will need to implement a central system to monitor both individual and overlapping system usage. They should create a Data Center in the corporate office that monitors all of the current systems in place. This will allow Riordan Manufacturing to understand how their business is functioning and how application are used more often and which are not utilized enough, helping to determine if they should upgrade or discontinue the use of a system. Each department uses different applications; some of the applications interface with one another and other are stand alone. Riordan also currently has a lot of manual processes, for example how they submit daily inventory records. With the overall updates that our team has posed have more automation will assist Riordan to increase their production and accuracy. We can implement an application that can be used by all of the centers in order to maintain the inventory across the board so the managers are able to see what is in high demand in specific locations. Having an overall view of the inventory will be beneficial to the entire company. If the marketing department has he ability to see the inventory usage then they will know where they need to market certain products better. We...

...Nicholas Richards 23/09/2015 Prin. of Man. Shark Tank paper BuggyBeds When viewing videos for this paper I saw some pretty great and just some not so great products. But one stood out to me from all the others. During the show for this product, two women presents the Sharks with a product called BuggyBeds. This product was presented as an early detector for bed bugs around the house. These monitors attract bed bugs to the trap and keep them trapped using a special formulated glue. As stated by both women pitching their product, the glue is not poisonous and is not harmful to people, which is a must if little kids are around. The monitors themselves are very small and easy to use. All one has to do is unpack the monitor and then place it around the area/furniture one thinks might contain bed bugs, preferable under the desired object. I found it interesting while watching this bit show when one of the women informed the Sharks that there really is not a lot of early detection systems for bed bugs. For them to produce a two-pack it just costs about ~ $1.60 – 1.75, and then they may market the product for about $6.99. I choose this product that will sell/win because of just how big a problem bed bugs are for a huge number of people and organizations. One fact stated by the women pitching this product is that a female bed bug can produce upwards to 500 more bed bugs. That is frightening, without anyway to deal with bed bugs they would just keep appearing. To me, I feel like...

...CASE STUDY – Organizational Behavior, Week 2 NO RESPONSE FROM MONITOR TWENTY-THREE* Robert D. Joyce, Innovative Management Loudspeaker: IGNITION MINUS 45 MINUTES. Paul Keller tripped the sequence switches at control monitor 23 in accordance with the countdown instruction book just to his left. All hydraulic systems were functioning normally in the second stage of the spacecraft booster at checkpoint 1 minus 45. Keller automatically snapped his master control switch to GREEN and knew that his electronic impulse along with hundreds of others from similar consoles within the Cape Kennedy complex signaled continuation of the countdown. Free momentarily from data input, Keller leaned back in his chair, stretched his arms above his head, and then rubbed the back of his neck. The monitor lights on console 23 glowed routinely. It used to be an incredible challenge, fantastically interesting work at the very fringe of man’s knowledge about himself and his universe. Keller recalled his first day in Brevard County, Florida, with his wife and young daughter. How happy they were that day. Here was the future, the good life . . . forever. And Keller was going to be part of the fantastic, utopian future. Loudspeaker: IGNITION MINUS 35 MINUTES. Keller panicked! His mind had wandered momentarily, and he lost his place in the countdown instructions. Seconds later he found the correct place and tripped the proper sequence of switches for checkpoint 1 minus 35. No problem....

...------------------------------------------------- Mouse (computing) From Wikipedia, the free encyclopedia A computer mouse with the most common standard features: two buttons and a scroll wheel, which can also act as a third button. A mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface. Physically, a mouse consists of an object held under one of the user's hands, with one or more buttons. The mouse sometimes features other elements, such as "wheels", which allow the user to perform various system-dependent operations, or extra buttons or features that can add more control or dimensional input. The mouse's motion typically translates into the motion of a pointer on a display, which allows for fine control of a graphical user interface. ------------------------------------------------- Naming The earliest known publication of the term mouse as a pointing device is in Bill English's 1965 publication "Computer-Aided Display Control".[1] The online Oxford Dictionaries entry for mouse states the plural for the small rodent is mice, while the plural for the small computer connected device is either mice or mouses. However, in the usage section of the entry it states that the more common plural is mice, and that the first recorded use of the term in the plural is mice as well (though it cites a 1984 use of mice when there were actually several earlier ones).[2] The term mice was seen in print in "The Computer as a...

LCD의 구조 및 동작 원리 LCD 구동방식에는 능동방식(AM: active matrix)과 수동방 식(PM: passive matrix)이 있다. 수동방식 LCD에 주로 사용 되는 STN LCD는 고해상도와 고계조의 표현이 어렵기 때문 에, 대부분의 LCD 디스플레이 장치는 TFT를 이용하는 능동 방식이 적용되어 있다. 능동 방식의 LCD에서는 STN 액정의 응답속도가 느리기 때문에, 응답속도가 빠르고, 그림 1에서처 럼 계조 표시가 쉬운 TN(twisted nematic) 액정을 사용한다. 유도 분극현상 때문에 전압을 걸어주면 액정 분자 배열의 기울기가 달라지는데 이것을 이용하여, 빛의 투과율을 조절한 다. 자연광과 같은 경우 모든 방향으로 진동하는 빛으로는, 투과율을 조절할 수 없다. 그래서 액정의 양쪽에 편광판을 배 치하여 일정한 방향으로 진동하는 빛만 통과시킨다. 저자약력 ...

...Chapter I INTRODUCTION Nowadays, computers are very common in a household. Computers are very advantageous which actually has unlimited capabilities; in seeking a certain information, for recreation, for entertainment purposes and many other uses. But despite those infinite uses of computers, some say that computers cause detrimental effects to those who are exposed to its radiation. Radiation, in Physics, it is defined as the process of transmitting energy through space. There are two types of radiation exposure—82% is from natural resources such as cosmic and solar rays and 18% of the exposure is from man-made radiation. Radiation injures the body by destroying cells and parts of cells. It hinders cells from dividing which gives rise to cells which does not have the ability to reproduce. The reason why the researchers have chosen this topic is to stress out the hazardous effects of computer radiation.Long-term exposure to radiation increases the risk of all forms of cancer, tumors, blood disorders, miscarriage, headaches, insomnia, anxiety, aging of the skin, skin burn, etc. Radiation exposure over time can cause skin burn, dry wrinkled skin and photo aging. This skin damage is identical to sun damage and causes the same health problems. Many electronic products that we use on a daily basis expose us to harmful radiation. A television, microwave oven, cellular phone and computer are examples of...

...sizes, but the most common are the 50 pin connector for the A-type narrow SCSI cable, and the 68-pin connector for the p-type wide SCSI cable. IEEE 1394 also known as fire wire uses serial communication, it is very fast, hot swappable, and is especially useful when transmitting streaming media. Multimedia devices such as microphones, earphones, and speakers are usually located at the back of the CPU, but in some cases there is a second set on the front of the computer as well. Clip 2 Summary: There are two types of computer monitors on the market today, the older CRT monitors, which are big and bulky and the newer LCD monitors which take up less desk space.CRT monitors use cathode ray tubes and LCD monitors use a technology called TET also referred to as active matrix. Refresh rate and response time are both terms used to refer to the amount of time it takes to create a new image on the screen. CRT monitors supports many resolutions but an LCD monitor is designed to support a fixed resolution called native...

...An individual that is computer literate has many advantages in life. All high-paying jobs require its employee to be computer literate. This skill is a must in order to be successful in the workforce. Computers have become a part of our everyday lives. Life would be very difficult without them. I am very computer literate. Working on computers became a hobby of mines back in high school. Operating on one is not an easy task if one has no idea of what he or she is doing. I started out make many mistakes on computers before I became an expert at them. For example, my grandmother bought me a computer for Christmas and I was the happiest kid in the candy store. I immediately went to the games section and enjoyed them to the fullest. One day, I began to run low on disk space and decided to go into my system files and delete random files and folders that I thought were useless to the computer. Sure enough they were useless until my computer displayed symbols and signs where text should have been. It was as if my computer exhibited a different language but only through different shapes and signs. I was terrified that I had done this to my computer! My mom later called customer service to resolve the problem, but never again did I go into my system and delete random files unless I knew exactly what I was deleting! I’ve learned a lot from my mistakes on working with computers. I am now a pro in the field of computers. I’ve had clients in the past that I have worked...

...BRIEF CASES HARVARD 'BUSINESS PUBLISHING 4440 APRIL 2 7 , 2 0 1 2 DOROTHY LEONARD SUNRU YONG Bella Healthcare India Joseph Cherian, country director of Bella Healthcare in India, wondered whether his team was ready for Project TKO. He listened intently as Jeremy Manning, his director of research and development, described the pros and cons of the project, a proposal to develop a new portable electrocardiograph machine (EKG) specifically for the Indian market. Cherian believed the time was right to tackle the tough, but fast-growing Indian market. The key question was whether Bella India's local R&D team, under Manning's direction, was ready to lead the product development: My goal has always been to develop products that serve emerging markets and make healthcare more accessible. I think medical device companies are learning that this can be done most effectively by those who know these markets best. We should develop our affordable EKG in India, for India. Bella India has proven itself in manufacturing and costengineering; this is the next logical step. The endeavor was not without risk. The costly failure of Project Baton, a global product development effort, was fresh on everyone's mind. Failure with Project TKO would not only hurt Bella Healthcare's overall profitability, it would undermine Cherian's case that the India operation was ready for more challenging product development undertakings. £ | ^E o^| f§§ l^ff 21 ® ggo >^ 8 | j> | ^ji f£ | %^ E 111 I- |...

...Health Hazards in the IT profession When you tell someone you are in the IT profession they usually come back with something like “oh so you get to sit around all day playing on a computer!” The truth is there are lots of risks with “sitting around playing on a computer”. Being at a desk and in front of a computer can be just as hazardous as being a construction worker or a mover for a moving company. There are health hazards that go along with sitting all day. Blood clots from lack of movement, the lighting of the computer screen which cause headaches and eye strain. With a busy work environment, often time there is no time for a nice long lunch hour which leads to grabbing something quick and usually not the healthiest on the menu. This is just to name a few of the problems with being an IT. It’s hard to believe an industry such as Information Technology can actually be hazardous to your health. Did I mention stress? Although there are a lot of physical issues that come with the IT profession, I would like to focus on the stress of the IT profession. It was not long ago that I worked in an office environment and had no idea what it took to be an “IT person”. I was one of the many that complained about how long it took to get and IT person to look at my computer to see what was wrong with it. Until now, I had no idea. With the tighter budgets caused by the economic strain, there has been a problem with understaffing in the IT field. Unfortunately, understaffing...
