Pojectile Motion

...Lab # 111 “Projectile Motion” Objectives : The purpose of this lab is to understand projectile motion in two dimensions and apply linear motion equations to solve the problem. Also to predict where a given size bullet to be placed in horizontal direction to leaving table. In addition to that measure the range of projectile leaving table at an angle, and use the value to predict where the projectile bullet to strike at floor. Theory : To predict where bullet will land on the floor when lunched from the mini launcher from a table at an angle, but to do that first we need to determine the velocity of the bullet and to determine by launching the bullet horizontally from the table and measuring the vertical and horizontal distances through distance that the bullet travels. Then the initial velocity can be used to calculate where the bullet will land when the bullet lunched from the mini launcher at an angle. Horizontally lunched bullet at θ=0 off a table with an initial speed, vo, the horizontal distance travelled by the bullet and the vertical distance of the bullet drop in time t describe: x= v0t (1) y=v0yt+12gt2 (2) Now we can determine the initial velocity of the bullet by measuring x and y. where y = 0, therefore, the time of the bullet can be found by equation: t= 2yg, Where g = 9.8 (3) Now, to guess the range of the bullet, x, at and angle, θ, above horizontal, we guess the time of the bullet using vertical motion equation: 12gt2-(v0sinθ)t-H=0...

...Research In Motion Ltd. (RIM) is a company known primarily for its BlackBerry devices and e-mail services. Throughout the early years of its career, RIM has faced many patent infringement suits regarding their wireless devices but one of them that lasted from 2001-2006 stands out among the herd. This specific case was the one between NTP (New Technologies Products) owner Mr. Campana and RIM’s owner Mr. Lazaridis over wireless e-mail patents. This ongoing battle between companies could have ended as soon as it began, but RIM’s actions dug them into a financial hole and put their customers in a state of panic. Research in Motion was founded in 1984 in Waterloo, Ontario by Mike Lazaridis who always had a passion for inventing (International Directory of Company Histories). Lazaridis from the early age of 8 gravitated toward technology constructing a pendulum clock out of Legos and in high school, built a working computer (Mckenna, Waldie, & Avery). Even in college he was focused and seemed mature for his years. He eventually dropped out of college, however, and started RIM with the backing of friends and family. Their first contract came from General Motors of Canada and for years after that moved from contract to contract. In the early 90’s, RIM became interested in digital wireless devices when Rogers Cantel Mobile Communications Inc, a paging and cellular telephone operator, contracted with them (International Directory of Company Histories). From this point on, RIM...

...Research In Motion Limited (RIM) is a Canadian telecommunication and wireless device company best known for developing the Blackberry Smartphone. RIM has his headquarters in Waterloo, Ontario, Canada and is a sponsor of RIM Park in the northeast of the city. Founded by Mike Lazaridis, who currently serves as its co-CEO along with Jim Balsillie were keenly interested in this project. History Preceding the time of manufacture of the Smartphone, RIM worked with RAM Mobile Data and Ericsson to turn the development of Ericsson’s Mobitex wireless data network into a two-way paging and wireless e-mail network. The most important in this development was the release of the Interactive pager 950, which started shipping in August 2000. The size of this is about like the bar soap. This device competed against the SkyTel two-way paging network developed by Motorola. Canadian institutional and venture capital investors in 1995 sponsored RIM’s initial development through a private placement in the privately-held company. Working Ventures Canadian Fund Inc. led the first venture round with a $5,000,000 (CAD) investment with the proceeds being used to complete the development of RIM's two-way paging system hardware and software. A total of $30,000,000 (CAD) in pre-IPO financing was raised by the company prior to its initial public offering on the Toronto Stock Exchange in January, 1998 under the symbol RIM. RIM has released a variety of devices running on GSM, CDMA, and Motorola iDEN...

Research in Motion

...Research in Motion Research in Motion Limited (RIM) as it is also known as a maker of Blackberry was founded in 1984 by Douglas Fregin and Mike Lazaridis. Both were engineering students when they first started out. RIM started out as a wireless and telecommunications equipment company which was based in Waterloo, Canada. One of Rim’s main target customers were business and government organizations (Wikipedia, 2014). In my opinion, I would say that RIM was the first to come out with an innovation and technology for smartphones. It had a vision for the future, and it was after they came out with their first Blackberry smartphone in 2000 that companies such as Apple and Samsung followed suit. When the Blackberry first came out in 2000, RIM faced its first and biggest challenge on its intellectual property in which it was sued by NTP. NTP is a Virginia based patent holding company that was founded in 1992. NTP is a non-practicing entity which enforces its patent portfolio against larger organizations (Wikipedia, 2014). NTP requested RIM to license its patents and Charles Meyer, RIM’s in-house attorney concluded that there was no violation (Teska, 2006). The lawsuit was ongoing for six years until in 2006 the US Justice Department decided to intervene and warned that the network would be shut down as the government was relying on blackberry (Hill, 2013). RIM then finally decided to pay NTP $612.5 million the amount that would cover past and future use of the patents. Interestingly...

...10/1/2012 Submitted to : Prof. Daniel Atiff   RIM has been facing massive problems ranging from top executives leaving the company to patent suits. Instead of washing its dirty lien in public has taken a stand to remain silent and progress among all chaos. To revive the company’s reputation, Thorsten Heins took over as CEO in Jan. 2012. After he declared the Earnings report & announced the release of OS BB10 on 25 September’2012, the company’s shares have started to increase in value again. Expected Actual Difference Revenue $2.47 Billion $2.9 Billion $43 Million(+) Adjusted EPS 0.27 0.47 0.20 Sales 7.8 Million 7.4 Million 0.4 Million It is apparent that RIM if at all it starts progressing again after BB10 release will need a long time to reposition itself back to glory days. But blackberry have had so much to deliver to its customers from “PUSH-Technology” to end-to-end security to now placement and integration of fuel cells in its devices which enables the blackberry to recharge itself. These amazing features are unique. Even more unique is the fact that not a single blackberry phone has been hacked till date which makes Blackberry the safest smart-phones among its competitors. Aware consumers have high expectations from BB10 which even provides multi-language support in a single text message. Recommendations:  Rim must work on 3 areas to help position itself back to zenith days: Internal Management, Timeline adherence, new innovations and patents...

Research in Motion Study

...Eric H. Hill Research In Motion (RIM), (NETW583) November 17, 2014 RIM faced considerable challenges in protecting its intellectual property with enormous outlays of cash to protect its property. These court battles were long, drawn, over many years and in several countries. This extended RIM in too many directions, in too many places. These legal forays into protecting and acquiring patents shifted RIMs focus from an offensive posture of developing new technology for the marketplace through its R & D to a defensive posture of acquiring ill- suited technology to secure its future. When companies lose focus on innovation and risk taking they have lost their edge. Others are looking to overtake them. In fact, Apple did just that to RIM as the iPhone toppled the once mighty BlackBerry. While many tech companies consider purchasing patents a necessary evil it should exceed the R&D budget. Unfortunately, competitors will often let the behemoths fight among themselves for patented technology while they innovate something completely new. This can give smaller competitors an edge. RIM’s corporate philosophy was to partner or collaborate rather than to innovate. This is a flawed philosophy which ultimately leads to a company’s demise. This was certainly the case with RIM as it became too diverse with too many partners and no real focus on a core item. The BlackBerry tried to compete with antiquated technology or simply missed technological advances because of a tone...

Force and Motion

...Force & Motion The First Law: Force and Inertia Object remains at rest will remain at rest unless acted upon by unbalanced force. Object in motion will continue at constant speed and motion unless acted upon by unbalanced force. Force is an action that can change motion. A force is what we call a push or a pull, or any action that has the ability to change an object’s motion. Forces can be used to increase the speed of an object, decrease the speed of an object, or change the direction in which an object is moving. Classification of Forces 1. Effects on motion- Balanced forces produce no motion or motion with constant velocity, while unbalanced force produce accelerated motion. 2. Line of Action- Parallel forces may go in the same direction or in opposite directions while Concurrent forces are those that meet at a point. 3. Relations to Work- Conservative forces are those that can do work and can stores energy. Non conservative are forces that can do work but cannot store energy. 4. Interaction of Bodies- Contact force when object is push by another & Distant force no contact between objects. Equilibrium 1. Stable- line passed through its center of gravity falls within the base. 2. Unstable- line dropped through the center of gravity does not fall with in the base. 3. Neutral- Does not change the center of gravity with slight tipping. Inertia is a term used to measure the ability of an object to resist a change in its state of...

Motion Capture Technology

...Planet the Apes that starred James Franco. As this sequel begins, Franco's character has been dead for a decade, and the apes have had plenty of time to create their version of civilization. But in real time, it's been just three years since the Rise movie. In the world of motion picture technology, though, that's an eternity. Long enough to create computer graphics gear robust enough to take out of the studio and deep into a real forest. And long enough that moviemakers no longer need to give a recognizable Hollywood star top billing to bring in audiences. In fact, if you passed the leading man of Dawn—Andy Serkis—on the street, you wouldn't recognize his face at all, for you never see it on the screen. That's because his performance in the woods (actually, forests near Vancouver, not San Francisco) wasn't fillmed traditionally, it was motion captured, and used as a framework for a computer-created realistic digital ape, Caesar. And, for the first time in my knowledge, it's the performances of the motion capture actors, not the regular actors portraying humans, that are getting all the good reviews from critics; there is even talk of the first best-actor Oscar nomination for a motion-capture performance. Motion capture enables moviemakers to create realistic non-human characters—including Gollum in Lord the Rings, the Na’vis of Avatar, and the intelligent chimpanzees and orangutans of Rise of the Planet the Apes. It has also let moviemakers digitally tweak human characters, aging...

Motion Study

...Motion Study of Gilbreths in Surgery Frank and Lillian Gilbreth are best-known for their motion study on bricklaying. However they did many other studies on various areas. They have motion studies for athletes, pianists , book keepers and fencers. All of these people were photographed when they were in action. Then those actions were divided into small micro motions to observe the unnecessary movements to eliminate. Surgeons were those people that Gilbreths studied on to improve the surgical operations by eliminating the unnecessary motions. Back in the days, the operations were taking so long because the doctors were trying to find the surgical instruments while operating. They had to stop and look for the equipment which was needed for the next action. Additionally, surgical practices and the instruments varied in the country which resulted incompetence. Gilbreths thought that the scientific management in industry can be applied to the surgical area and they decided to conduct a motion study in this area. Gilbreths observed the surgeons while they were doing the operation and saw that seeking for the surgical instrument took a great amount of time for surgeons that they always needed to stop for some time to get the next equipment. However, Gilbreths had hard time to convince the surgeons to get permission from them to attend their operations because Gilbreths needed to observe them. At first surgeons seemed willing to have Gilbreths in their surgical operations but...
