Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms DAS, DAQ, or DAU, typically convert analog waveforms into digital values for processing. The components of data acquisition systems include:

86-412: A PC motherboard or in a modular crate ( CAMAC , NIM , VME ). Sometimes adapters are needed, in which case an external breakout box can be used. DAQ cards often contain multiple components (multiplexer, ADC, DAC, TTL-IO, high-speed timers, RAM). These are accessible via a bus by a microcontroller , which can run small programs. A controller is more flexible than a hard-wired logic, yet cheaper than
129-429: A market inefficiency , which undervalues the true strength of these stocks. In her 1999 book No Logo , Naomi Klein provides several examples of mergers and acquisitions between media companies designed to create conglomerates to create synergy between them: A relatively new development, Internet conglomerates, such as Alphabet , Google's parent company belong to the modern media conglomerate group and play

For example: Waiting for a trigger, starting the ADC, looking up the time, waiting for the ADC to finish, move value to RAM, switch multiplexer, get TTL input, let DAC proceed with voltage ramp. Today, signals from some sensors and Data Acquisition Systems can be streamed via Bluetooth. DAQ device drivers are needed for the DAQ hardware to work with
258-480: A disorienting and demoralizing experience for executives at acquired companies—those who were not immediately laid off found themselves at the mercy of the conglomerate's executives in some other distant city. Most conglomerates' headquarters were located on the West Coast or East Coast , while many of their acquisitions were located in the country's interior. Many interior cities were devastated by repeatedly losing
301-540: A focus in Asia.) In Japan, a different model of conglomerate, the keiretsu , evolved. Whereas the Western model of conglomerate consists of a single corporation with multiple subsidiaries controlled by that corporation, the companies in a keiretsu are linked by interlocking shareholdings and a central role of a bank. Mitsui , Mitsubishi , Sumitomo are some of Japan's best-known keiretsu, reaching from automobile manufacturing to
344-831: A major role within various industries, such as brand management . In most cases, Internet conglomerates consist of corporations that own several medium-sized online or hybrid online-offline projects. In many cases, newly joined corporations get higher returns on investment , access to business contacts, and better rates on loans from various banks. Similar to other industries many companies can be termed as conglomerates. Data acquisition Data acquisition applications are usually controlled by software programs developed using various general purpose programming languages such as Assembly , BASIC , C , C++ , C# , Fortran , Java , LabVIEW , Lisp , Pascal , etc. Stand-alone data acquisition systems are often called data loggers . There are also open-source software packages providing all
387-495: A noise vibration and harshness lab; a metrology lab; and a materials engineering lab. Conglomerate (company) A conglomerate ( / k ə ŋ ˈ ɡ l ɒ m ə r ə t / ) is a type of multi-industry company that consists of several different and unrelated business entities that operate in various industries. A conglomerate usually has a parent company that owns and controls many subsidiaries , which are legally independent but financially and strategically dependent on
430-625: A small slice of many companies in a fund rather than owning shares in a conglomerate. Another example of a successful conglomerate is Warren Buffett 's Berkshire Hathaway , a holding company which used surplus capital from its insurance subsidiaries to invest in businesses across a variety of industries. The end of the First World War caused a brief economic crisis in Weimar Germany , permitting entrepreneurs to buy businesses at rock-bottom prices. The most successful, Hugo Stinnes , established
473-400: Is a collection of software and hardware that allows one to measure or control the physical characteristics of something in the real world. A complete data acquisition system consists of DAQ hardware, sensors and actuators, signal conditioning hardware, and a computer running DAQ software. If timing is necessary (such as for event mode DAQ systems), a separate compensated distributed timing system

A chaebol is also inheritable, as most of the current presidents of chaebols succeeded their fathers or grandfathers. Some of the largest and most well-known Korean chaebols are Samsung , LG , Hyundai Kia and SK . In India, family-owned enterprises became some of Asia's largest conglomerates, such as
559-612: Is required. A sensor , which is a type of transducer , is a device that converts a physical property into a corresponding electrical signal (e.g., strain gauge , thermistor). An acquisition system to measure different properties depends on the sensors that are suited to detect those properties. Signal conditioning may be necessary if the signal from the transducer is not suitable for the DAQ hardware being used. The signal may need to be filtered, shaped, or amplified in most cases. Various other examples of signal conditioning might be bridge completion, providing current or voltage excitation to

Escorts Auto Products manufactures auto suspension products such as shock absorbers, struts, and telescopic front forks for the automotive industry . The company collaborated with Fichtel & Sachs to introduce the concept of shock absorbers to be manufactured in India in 1966. In 2016, Escorts' Auto Products business
731-641: The United States , conglomerates became popular in the 1960s as a form of economic bubble driven by low interest rates and leveraged buyouts. However, many of them collapsed or were broken up in the 1980s due to poor performance, accounting scandals, and antitrust regulation. In contrast, conglomerates have remained prevalent in Asia, especially in China , Japan , South Korea , and India . In mainland China , many state-affiliated enterprises have gone through high value mergers and acquisitions , resulting in some of
774-572: The highest value business transactions of all time. These conglomerates have strong ties with the government and preferential policies and access to capital. During the 1960s, the United States was caught up in a "conglomerate fad " which turned out to be a form of an economic bubble . Due to a combination of low interest rates and a repeating bear-bull market , conglomerates were able to buy smaller companies in leveraged buyouts (sometimes at temporarily deflated values). Famous examples from
817-470: The physical phenomenon or physical property to be measured. Examples of this include temperature, vibration, light intensity, gas pressure, fluid flow, and force. Regardless of the type of physical property to be measured, the physical state that is to be measured must first be transformed into a unified form that can be sampled by a data acquisition system. The task of performing such transformations falls on devices called sensors . A data acquisition system
860-440: The 1960s include Gulf and Western Industries , Ling-Temco-Vought , ITT Corporation , Litton Industries , Textron , and Teledyne . The trick was to look for acquisition targets with solid earnings and much lower price–earnings ratios than the acquirer. The conglomerate would make a tender offer to the target's shareholders at a princely premium to the target's current stock price. Upon obtaining shareholder approval,
903-618: The 1980s, General Electric also moved into financing and financial services , which in 2005 accounted for about 45% of the company's net earnings. GE formerly owned a minority interest in NBCUniversal , which owns the NBC television network and several other cable networks . United Technologies was also a successful conglomerate until it was dismantled in the late 2010s. With the spread of mutual funds (especially index funds since 1976), investors could more easily obtain diversification by owning

Another such conglomerate is J.D. Irving, Limited , which controls a large portion of the economic activities as well as media in the Province of New Brunswick . Some cite the decreased cost of conglomerate stock (a phenomenon known as conglomerate discount ) as evidential of these disadvantages, while other traders believe this tendency to be
1075-527: The brand names Farmtrac, Powertrac, and Steeltrac. The first Escorts tractors were produced in 1961 based on Ursus license. In 1969, a partnership with Ford was set up to produce licensed Ford tractors for India. Escorts has a plant in Mrągowo , Poland , that was purchased from Pol-Mot in 2000, and four plants in India. There was an assembly plant in Tarboro, North Carolina , that was purchased from Long Agri, but

The company manufactures tractors under
1161-455: The conglomerate usually settled the transaction in something other than cash, like debentures , bonds , warrants or convertible debentures (issuing the latter two would effectively dilute its shareholders down the road, but many shareholders at the time were not thinking that far ahead). The conglomerate would then add the target's earnings to its earnings, thereby increasing the conglomerate's overall earnings per share . In finance jargon,
1204-462: The end came in January 1968, when Litton shocked Wall Street by announcing a quarterly profit of only 21 cents per share, versus 63 cents for the previous year's quarter. This was "just a decline in earnings of about 19 percent", not an actual loss or a corporate scandal, and "yet the stock was crushed, plummeting from $ 90 to $ 53". It would take two more years before it was clear that the conglomerate fad

In
1290-699: The headquarters of corporations to mergers, where ventures were reduced to subsidiaries of conglomerates based in New York or Los Angeles. Pittsburgh, for example, lost about a dozen. The terror instilled by the mere prospect of such harsh consequences for executives and their home cities meant that fending off takeovers, real or imagined, was a constant distraction for executives at all corporations seen as choice acquisition targets during this era. The chain reaction of rapid growth through acquisitions could not last forever. When interest rates rose to offset rising inflation, conglomerate profits began to fall. The beginning of
1333-503: The most powerful private economic conglomerate in 1920s Europe – Stinnes Enterprises – which embraced sectors as diverse as manufacturing, mining, shipbuilding, hotels, newspapers, and other enterprises. The best-known British conglomerate was Hanson plc . It followed a rather different timescale than the U.S. examples mentioned above, as it was founded in 1964 and ceased to be a conglomerate when it split itself into four separate listed companies between 1995 and 1997. In Hong Kong, some of

1376-572: The necessary tools to acquire data from different, typically specific, hardware equipment. These tools come from the scientific community where complex experiment requires fast, flexible, and adaptable software. Those packages are usually custom-fit but more general DAQ packages like the Maximum Integrated Data Acquisition System can be easily tailored and are used in several physics experiments. In 1963, IBM produced computers that specialized in data acquisition. These include
1419-653: The new businesses they had recently purchased, and by the mid-1970s most conglomerates had been reduced to shells. The conglomerate fad was subsequently replaced by newer ideas like focusing on a company's core competency and unlocking shareholder value (which often translates into spin-offs ). In other cases, conglomerates are formed for genuine interests of diversification rather than manipulation of paper return on investment. Companies with this orientation would only make acquisitions or start new branches in other sectors when they believed this would increase profitability or stability by sharing risks. Flush with cash during
1462-731: The parent company. Conglomerates are often large and multinational corporations that have a global presence and a diversified portfolio of products and services. Conglomerates can be formed by merger and acquisitions , spin-offs , or joint ventures . Conglomerates are common in many countries and sectors, such as media , banking , energy , mining , manufacturing , retail , defense , and transportation . This type of organization aims to achieve economies of scale , market power, risk diversification , and financial synergy. However, they also face challenges such as complexity, bureaucracy , agency problems, and regulation . The popularity of conglomerates has varied over time and across regions. In

1548-540: The sensor, isolation, and linearization. For transmission purposes, single ended analog signals , which are more susceptible to noise can be converted to differential signals . Once digitized, the signal can be encoded to reduce and correct transmission errors. DAQ hardware is what usually interfaces between the signal and a PC. It could be in the form of modules that can be connected to the computer's ports ( parallel , serial , USB , etc.) or cards connected to slots ( S-100 bus , AppleBus, ISA, MCA , PCI, PCI-E, etc.) in
1591-406: The transaction was " accretive to earnings." The relatively lax accounting standards of the time meant that accountants were often able to get away with creative mathematics in calculating the conglomerate's post-acquisition consolidated earnings numbers. In turn, the price of the conglomerate's stock would go up, thereby re-establishing its previous price-earnings ratio, and then it could repeat
1634-425: The well-known conglomerates include Jardine Matheson (AD1824), Swire Group (AD1816), (British companies, one Scottish one English; companies that have a history of over 150 years and have business interests that span across four continents with a focus in Asia.) C K Hutchison Whampoa (now CK Hutchison Holdings ), Sino Group , (both Asian-owned companies specialize business such as real estate and hospitality with
1677-663: The whole process with a new target. In plain English, conglomerates were using rapid acquisitions to create the illusion of rapid growth. In 1968, the peak year of the conglomerate fad, U.S. corporations completed a record number of mergers: approximately 4,500. In that year, at least 26 of the country's 500 largest corporations were acquired, of which 12 had assets above $ 250 million. All this complex company reorganization had very real consequences for people who worked for companies that were either acquired by conglomerates or were seen as likely to be acquired by them. Acquisitions were

The motorcycle division of Escorts group used to manufacture Polish SHL M11 175 cc (10.7 cu in) motorcycles under the brand name Rajdoot from the early 1960s until 2005. In the early 1980s, Escorts started making Yamaha motorcycles in India. Rajdoot 350 was launched in 1983, which was later followed by the Yamaha RX 100 in 1985. The "RX" name signified "Rajdoot × Yamaha". The motorcycle manufacturing unit in Faridabad, India,

1806-487: Was on its way out. The stock market eventually figured out that the conglomerates' bloated and inefficient businesses were as cyclical as any others—indeed, it was that cyclical nature that had caused such businesses to be such undervalued acquisition targets in the first place —and their descent put "the lie to the claim that diversification allowed them to ride out a downturn." A major selloff of conglomerate shares ensued. To keep going, many conglomerates were forced to shed
1849-477: Was sold to Yamaha in 2001 when Escorts decided to quit the motorcycle business to concentrate on tractors and auto components. The Escorts Knowledge Management Centre (KMC) was created in 1976 and is spread over 100,000 square metres (0.039 sq mi) in Faridabad. The centre designs tractors. It has facilities such as an engine laboratory that has computerised test beds with online control, data acquisition , and analysis; an advanced vehicle testing laboratory;
