...The circuit uses the AC signals generated at the buzzer terminals of an alarm clock. The AC signals are amplified by transistors T1 and T2 and the amplified output from the emitter of T2 is fed to the inverting input of negative-voltage comparator IC LM311 (IC1). The non-inverting input of IC1 gets a presettable voltage through preset VR1. The inverting and non-inverting inputs of LM311 are different from other op-amps and it outputs sink current through pin 7 or source current through pin 1. When pin 3 of IC1 is at a higher voltage than pin 2, its output sinks as indicated by LED1. This gives a short negative pulse to the monostable wired around timer NE555. Resistor R5 keeps trigger pin 2 of IC2 high. The short-interval monostable outputs a high signal for a brief period to the gate of SCR1 (BT169) and relay RL1 energises. The latching action of SCR1 keeps the relay pulled even when the output of the monostable turns low. The relay can be de-energised by disconnecting the supply to the circuit D. MOHAN KUMAR CLOCK TIMER S.C. DWIVEDI via switch S1. The circuit works off a 9V battery. Assemble it on a general-purpose PCB and enclose in a suitable cabinet. Provide an AC outlet in the cabinet to switch on the appliance using the circuit. As mentioned earlier, the input signal is obtained from the buzzer terminals of the clock. Remove the small buzzer of the clock and connect point ‘A’ to the positive terminal and point ‘B’ to the negative...

...distribute time around the world. It gets time from a reference called a time scale. They are several time scales in the world. In the US, NIST and USNO are used for the UTC time scale and are referred to as UTC (NIST) and UTC (USNO). USNO also produces the GPS time scale. The time scales around the world are coordinated through an international agency called BIPM. USNO, NIST are all coordinated to BIPM through a mechanism called two-way time transfer. BIPM defines International Atomic Time (TAI) from ensembling atomic clocks that are disseminated around the globe - the duration of the TAI second is kept as close as possible to the SI second. Coordinated Universal Time (UTC) is an atomic time scale derived from TAI to provide a reference scale in step with the irregular rotation of the earth. As a result of this process, the mean solar day, which is nominally 86400 seconds long, is actually getting longer when measured in SI seconds with stable atomic clocks. It is the role of IERS (International Earth Rotation Service) to observe the self-rotation of the earth and to make sure that when the earth completes its rotation - 24 hours have elapsed…. It does the same with respect to the earth’s rotation around the sun. As the earth slows down due to tidal effects, leap seconds have been used to adjust the time periodically since the original 1/1/1970 00:00:00 epoch. TAI is 35 seconds ahead of UTC today (dynamic value). TAI is always ahead of the GPS timescale by 19 seconds...

...Clocky – The Runaway Alarm Clock | Case Analysis Group 3 | | Problem Statement Even though Clocky was the center of the media hype, Gauri Nanda is faced with many pressing challenges and issues for its commercial debut in the marketplace: Analysis: 1. Industry Analysis The US alarm clock market in 2005 was quite fragmented with a significant number of players in the regular alarm clock as well as the niche alarm clocks segment. The Americans spent over $7 billion on clocks and watches. On an overall basis, the consumer spending on clocks, lamps and furnishing as a category showed a increasing growth trend. The imported watches segment was also growing at a CAGR of 4% since 2002. The alarm clock industry can be further analysed using the Porter’s model and generic strategies as shown below. Figure 1: Porter’s Five Forces Analysis Economies of Scale: In order to analyze the Economies of Scale in manufacturing of Clocky Alarm clock, we have divided the manufacturing unit of Clocky alarm into different segments. The major manufacturing units comprises of 1. Integrated Circuit Manufacturing Unit: The Integrated circuit industry shows a high economy of scale.

The sound of the keys clicking as words appear onscreen, each line seeming tedious and blurring together as it gets later and later, is the loudest sound in the night. Even when the work is finally finished, there is always more, and always another reason to stay up; to get that promotion, to improve a grade in school, or even due to a sleep disorder such as insomnia or sleep apnea, a disorder which causes a person to stop breathing briefly while they are sleeping, sometimes hundreds of times a night, depriving the brain of oxygen.

...Draft - Corporate Governance Considerations This material was prepared by Eliot H. Sherman – July 2005 FOCUS Learning Objectives By the end of this chapter, you should be able to: Understand the issues related to agency and delegated responsibility. Describe the similarities and the differences in the corporate scandals that have been identified in the past few years Identify the responsibilities of managers to the shareholders and other stakeholders associated with their corporations. OVERVIEW Corporate governance is not a new topic. It has been around for many years, often described as the “agency issue.” However, in recent years it has taken on increased significance, demanding increased attention. Since 2001, in particular, the corporate marketplace has seen a significant number of headline grabbing scandals involving major corporations. These scandals have raised new questions about corporate governance and, as a direct consequence of some of these situations, the U.S. Congress passed a very broad piece of legislation called the Sarbanes-Oxley Act of 2002. This law has had a wide range of consequences directly affecting large public corporations and public accounting firms and, less specifically, smaller public firms, private corporations, not-forprofit organizations and regulatory entities in many different ways. This law mandates some specific actions for large public corporations, many of these actions being required shortly after the legislation passed and others in...

...Abstract Planning to build a grandfather clock equipped me with the skills needed to make new friends. The commitment to finish what was started instilled in me the confidence to open my life up to another human on a deeper level. Utilizing the tools I had been equipped with, I was able to follow through with the plans I had laid out and made one of my dreams come true. Concrete Experience While attending a Bible study with some friends, I was captivated by the host’s grandfather clock ticking away the seconds in the living room. The size and beautifully articulated detail that it expressed kept my mind pondering what it would be like to create a time keeper. My friend Doug noticed my stares and inquired if I had interest in woodworking. I told him I would love to build one of those clocks! He suggested I stop by his house the following week for lunch and he would show me around his shop. The following week, after enjoying tomato soup and grilled cheese sandwiches, Doug and I walked out to his back yard and to my surprise he had a full woodworking shop. He showed me around the various projects he was working on and, whether boasting ornate detail or simple design, they were all magnificent projects to me. When we got to the back he told me he wanted to show me something. Doug leaned over pulling at a cloth from a large pile, he revealed planks of a cherry tree that had been milled and drying for seven years...

Perhaps the old place (возможно, /это/ старое имение: «место») had once been a great hunting tavern (когда-то было настоящей охотничьей таверной; great— большой, огромный, колоссальный, hunting— охота, поиски). These days, though (сейчас: «в эти дни», однако), the Hotel Stroh was plainly a disappointment (отель Строх был, очевидно, разочарованием; plainly— ясно, четко) to its few drooping tenants (для нескольких его изможденных постояльцев; todroop— наклоняться, сутулиться, изнемогать). They huddled together (они теснились /вместе/; tohuddle— сваливать в кучу, собирать вместе, съеживаться) like birds in a storm (как птицы /во время/ в грозу; storm— буря, ураган, шторм); their flesh sagged over the unscrubbed tables (их фигуры ссутулились над нечищеными столами: «их плоть обвисала над нечищенными щеткой столами»; flesh— тело, мясо, плоть, tosag— прогибаться, покоситься, обвисать, toscrub—...

...Business ethics Homework on the Clock The first thing that becomes obvious to me when watching this video, is that the employee here has lost his drive to succeed in his current position. Regardless of one’s drive to better themselves and further their education, it should be apparent to anyone that still values their current employment, that doing homework on company time is not a good way to go about it. He completes his work in an “auto-pilot” like mode, performing his routine required actions, but his mind and his intentions are elsewhere. Either he is passionate about things that have nothing to do with his current position and title, like chemistry, and/or he has lost all motivation for his current position and employer. If the person conducting the interview knew the actual truth of how he was able to get his degree, on paid company time, he would undoubtedly be unhappy, as would the superiors above him, if there are any. I suspect that corrective action would absolutely have to be taken, such as demotion or pay cut, suspension, and subsequent closer monitoring of his daily work routine. I doubt however, that he would be terminated completely from his position, as even if he does work on “auto-pilot” most of the time, he appears to be an important asset to the company, and even well-liked by the interviewer. From an ethical standpoint, I would think that it would be the interviewer’s duty at this point, to ensure that this kind of conduct did not occur again on...

...words of its founder, to "humanize technology." The company already has one hit: Consumers have snapped up more than 9,000 units of a $50 plastic alarm clock. Set the alarm for 6 a.m. When the time comes, the clock wheels itself off your bedside table and rolls around the room, emitting R2D2-like squeaks. Dubbed Clocky, the little robot is manufactured in China and sold online and in design boutiques. The company also has a line of handbags designed to accommodate laptops. The founder: Gauri Nanda designed Clocky as a graduate student in MIT's Media Lab. The daughter of entrepreneurs--her parents recently sold their small weekly newspaper in Detroit--she aspired to become a designer at a large technology company. "I was opposed to the idea of starting a company," says Nanda. "I saw the hours my parents worked." After presenting Clocky to her class in the fall of 2004, she threw it in the back of her closet. She'd almost forgotten about it until the next spring, when several tech bloggers stumbled upon a photo of her invention online. Suddenly, Nanda was getting contacted by reporters and TV producers. Good Morning America called. She scrambled to fix the buggy prototype in time for its debut on network TV. Nanda, now 27, left MIT with a master's degree that fall and began considering her options. Licensing the clock seemed like the easiest move, but she couldn't bring herself to give up control. "I had all these ideas about how it should look and behave," she says...

...Through the years, time has slowly taken over our lives. It eats away at our relationships and the work we do. Clocks, our way of measuring time, are why society has gone from leisurely to mechanical and rushed. They started as a way to count days and will soon be internalized. In ancient Babylon over 6 thousand years ago the sundial was used to track time. This was the first civilization to let time rule over them. From there Greece developed the first mechanical clock powered by water. Hamilton introduced the modern electric watch in 1957. As a major theme in Cast Away, time decides the decisions people make. Zemechis shows time in three different ways. Batina introduces timelessness. Technology and Chuck represent digital time. Biological time is shown through Kelly and the island. Batina represents the timeless world in Cast Away. When Zemechis introduces Batina she is a spark between two wings. This gives her a spiritual, angelic, or timeless character. There are also no clocks on the farm. This shows that Batina doesn’t let time rule over her. She enjoys her work and gets lost in the art she creates that will last forever. Batina only physically appears at the start and end of the film, but her symbol, the wings with three circles, is constantly there. When we see her four years later, she hasn’t changed. The world around her has gone...

...course of the whole human society, be it in any part of the world. If you are someone like Plato, you would say, there is no such thing like time that is making life hard for us. Instead, it is the idea of time that is responsible for all the commotion. Well, I do agree with such people and say, “The Clock is the culprit”, and enquire how this dire consequence happened to us. Unfortunately, to track how this at all happened, we should still rely on time, gazing back at the past, so that our arguments would make some sense. By this, we could say that, time is eternal to our lives. It neither has a beginning nor ending. The entire creation moves on according to a time pattern. Time is one of those many necessary evils that happened to us. Tracing back to history, we don’t have any evidence to suggest when the word ‘time’ derived or established semantically, but the word ‘clock’ is derived from the Latin word ‘clocca’ which means ‘bell’ or French word ‘cloche’, which again means the same. We were introduced to clocks only in the 14th century. It is in this period that people were familiarized with devices like sun dial, clepsydra or water clocks etc. Mechanical, tower and quartz clocks, with gears, wheels and weights attached to them were invented somewhere around the medieval period (5th – 15th century) in Europe. Be it towards human...

...through the story, even as Frank makes friends with shop owner Connor. These themes take a turn for a theme of hope as the story comes to a close and Frank meets Edie. A number of symbols and motifs are used in this story to represent the ups and downs of life and how knowledge and friendship can help anyone overcome their internal struggles. Three motifs that run through the story and illustrate the above ideas contained in the story are clocks, water and rings. The very first sentence of the story starts with the words “The digital clock in front of the Rockingham County Trust blinked off and, instantaneously, on again” (Mills 1). This suggests that time is an important theme in the story. We are further reminded of the importance of time in the second part of the same sentence – “it’s immense bright-red numerals informing Were Road that 9:12 had arrived on this mid-August Tuesday morning”(Mills 1). The way the sentence is framed suggests that time is both urgent and fast, and lazy and slow all at the same time. The blinking red numbers on the clock suggest urgency, but “mid-August Tuesday morning” sounds like it’s just another ordinary day. Time is only given rhythm in the way it is...

...The ongoing relationship between the literary movements of modernism and post-modernism is encompassed by the intertextual relationships between Stephen Daldry’s “The Hours” and Virginia Woolf’s “Mrs Dalloway”. These relationships communicate the inadequacy of previous writings to convey trauma, cultural crisis and the deep fragmentation within their respective societies. The immediate context of these social dialogues creates a clear division between each text, however the intertextual similarities between minor and major characters create an effective parallel to traverse decades, years, months and days. This is in order to assess the lasting impacts of society on an individual’s desire to escape either physically or metaphorically. Woolf’s 1923 novel “Mrs Dalloway” reflects on the need for a new convention to express the struggle of coming to terms with the lasting and catastrophic effects of modern warfare. Woolf achieved this through the binary oppositions of the inside and outside self. Woolf creates two alternate personalities within Clarissa through the use of parenthesise, punctuating the otherwise flowing modernist technique of free indirect discourse with Clarissa’s personal thoughts and opinions. The sub-commentary on the events offers the reader an alternate perspective to that provided by the narrator where upon Peter Walsh’s unexpected arrival “(she had been quite taken aback by this visit – it had upset her)”, and thus offers an insight into the private feelings...
