The latest Olympus camera is the Olympus OM-D E-M10 Mark IV as of 20 August 2020. Since then, Olympus has developed their two lines ( PEN and OM-D) and the Micro Four Thirds system, still alongside Panasonic. The first model in this family was the E-M5, released in 2012. It maintained the Micro Four Thirds system, but added a built-in electronic viewfinder, a more ergonomic button layout packaged in a retro style chassis. The market growth of the MILC cameras made Olympus introduce a new series in their lineup, which was the modern, digital implementation of the legendary OM series, the OM-D. Because it was very expensive, they made a cheaper option, called the Olympus PEN Lite E-PL1. The first Olympus-branded MFT camera was the Olympus PEN E-P1. The first product in the Micro Four Thirds system was the Panasonic Lumix DMC-G1, released in 2008. The lack of mirrors allowed the camera body to be a lot smaller than that of a DSLR, while maintaining its image quality and the interchangeability of the lenses. It was an interchangeable lens system, with the Four Thirds sensor size, and no mirrors ( Mirrorless Interchangeable Lens Camera). Olympus and Panasonic started a new development together, called the Micro Four Thirds system. ![]() Then, in 2017, after three years without a new lens, and seven years without a new body, Olympus officially discontinued the Four Thirds system Olympus OM-D E-M1 with an Olympus M.Zuiko Pro 12-40mm f2.8 lens After the introduction of the Micro Four Thirds system, and the general market growth of the Mirrorless Interchangeable Lens Cameras, the regular Four Thirds system became neglected. Olympus is also the largest manufacturer of Four Thirds lenses, under the Zuiko Digital brand. Olympus's Four Thirds system flagship DSLR camera is the E-5, released in 2010. Olympus manufactures compact digital cameras and is the designer of the Four Thirds system standard for digital single-lens reflex cameras. By 2001, the company's annual turnover from digital photography was in excess of ¥100 billion. The next year, Olympus hit the market with a 1.41 million pixel camera. As a result of his efforts, Olympus released an 810,000-pixel digital camera for the mass market in 1996, when the resolution of rivals' offerings was less than half. He fought for commitment by Olympus to enter the market in high-resolution photographic products. Tsuyoshi Kikukawa, who was later to become president of Olympus, foresaw the demand for the digital SLR, and is credited with the company's strategy in digital photography. A second version of the system was available the year after, but this was Olympus's last foray into the world of consumer video equipment until digital cameras became popular. In 1983, Olympus, along with Canon, branded a range of video recording equipment manufactured by JVC, and called it "Olympus Video Photography", even employing renowned photographer Terance Donovan to promote the range. Eventually the system included 14 different bodies, approximately 60 Zuiko-branded lenses, and numerous camera accessories. The OM system introduced a new trend towards more compact cameras and lenses, being much smaller than its competitors and presenting innovative design features such as off-the-film (OTF) metering and OTF flash automation. ![]() The Pen system design team, led by Yoshihisa Maitani, later created the OM system, a full-frame professional 35mm SLR system designed to compete with Nikon and Canon's bestsellers. Olympus Pen FT and 38mm f1.8 Zuiko lens Olympus OM Zuiko Lenses ![]() It used a half-frame format, taking 72 18×24 mm photographs on a standard 36-exposure 35mm film cassette, which made Pen cameras compact and portable for their time. The first innovative camera series from Olympus was the Pen, launched in 1959. The Olympus Chrome Six was a series of folding cameras made by Takachiho, and later Olympus, from 1948 to 1956, for 6×4.5 cm or 6×6 cm exposures on 120 film. In 1936, Olympus introduced its first camera, the Semi-Olympus I, fitted with the first Zuiko-branded lens. It paid $646 million in kickback fines in 2016. In 2011, Olympus attracted worldwide media scrutiny when it fired its CEO Michael Christopher Woodford, and the matter snowballed into a corporate corruption investigation with multiple arrests. Its global headquarters are located in Shinjuku, Tokyo, Japan. Olympus holds roughly a 70 percent share of the global endoscope market, estimated to be worth approximately US$2.5 billion. Olympus was established on 12 October 1919, initially specializing in microscopes and thermometers. Olympus Corporation ( オリンパス株式会社, Orinpasu Kabushiki-gaisha) is a Japanese manufacturer of optics and reprography products. History/origin: The origin of the term ounce stems from the Roman uncia, which means a "twelfth part," and the use of a standardized copper bar which defined both the Roman pound and foot. The avoirdupois ounce (the common ounce) is defined as exactly 28.349523125 grams and is equivalent to one sixteenth of an avoirdupois pound. ![]() Ounceĭefinition: An ounce (symbol: oz) is a unit of mass in the imperial and US customary systems of measurement. This is evidenced by the fact that the mass of the original prototype for the kilogram now weighs 50 micrograms less than other copies of the standard kilogram.Ĭurrent use: As a base unit of SI, the kilogram is used globally in nearly all fields and applications, with the exception of countries like the United States, where the kilogram is used in many areas, at least to some extent (such as science, industry, government, and the military) but typically not in everyday applications. Prior to the current definition, the kilogram was defined as being equal to the mass of a physical prototype, a cylinder made of a platinum-iridium alloy, which was an imperfect measure. The kilogram was originally defined as the mass of one liter of water at its freezing point in 1794, but was eventually re-defined, since measuring the mass of a volume of water was imprecise and cumbersome.Ī new definition of the kilogram was introduced in 2019 based on Planck's constant and changes to the definition of the second. This is at least in part due to the inconsistencies and lack of coherence that can arise through use of centimeter-gram-second systems, such as those between the systems of electrostatic and electromagnetic units. SI is a system based on the meter-kilogram-second system of units rather than a centimeter-gram-second system. Unlike the other SI base units, the kilogram is the only SI base unit with an SI prefix. History/origin: The name kilogram was derived from the French "kilogramme," which in turn came from adding Greek terminology meaning "a thousand," before the Late Latin term "gramma" meaning "a small weight." The changes were intended to improve the definitions of SI base units, not to actually change how the units are used throughout the world. Even though the definition of the kilogram was changed in 2019, the actual size of the unit remained the same. ![]() The meter and the second are defined in terms of c, the speed of light, and cesium frequency, Δ νCs. It is currently defined based on the fixed numerical value of the Planck constant, h, which is equal to 6.62607015 × 10 -34 in the units of J ![]() Definition: A kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI). ![]() Elevate also says that through its writing- and reading-based games, you'll also improve your memory and attention. With the games, you'll be challenged to broaden your vocabulary, improve your grammar and writing, and shore up your reading comprehension. If you want a way to engage your mind with quick, yet challenging puzzles, Lumosity is the pick for you.Įlevate's program has a more specific focus on communication. Lumosity bills itself as a way to work out your core cognitive abilities, and I believe it's a good general-purpose app for working on your more abstract mental skills, such as paying attention to details and making decisions. Lumosity and Elevate have different approaches to brain-training, and the two apps ultimately serve different purposes. That's part of the magic with Elevate - the games are short, sweet, and entertaining enough that you don't always feel like you're learning or exercising your brain, even when you are. Though the games sound like something you'd do in a high school English class, they are far more fun, challenging, and interesting than anything I was faced with in school. In some games, you read a sentence or short paragraph to get rid of errors or improve the grammar, in others you're listening to or reading informative passages, and are tested on key facts from the text. ![]() The idea is to improve your overall communication skills, and help you process information easier.Įvery Elevate game relies on either spoken or written text, instead of the shapes and patterns you'll find in Lumosity. The games focus on reading comprehension, looking or listening for grammatical errors, and improving your vocabulary. Screenshot by Sarah Mitroff/CNETĮlevate takes a different approach by helping you hone how you speak, listen, write, and read. Lumosity (left) focuses on training your memory and attention, while Elevate seeks to improve your communication skills. In the end, I think Elevate comes out ahead, but I encourage you to make your own judgements. I'm shining a light on those differences, to help you decide which brain-training app works better for you. Both apps have the same premise, but different designs and goals. That app focuses on a different set of skills than Lumosity, with an emphasis on writing, reading, and listening. At the same time I tested Lumosity, I also played around with Elevate. ![]() I recently reviewed Lumosity, and while I liked the idea behind the app, I felt the execution could be better. Other programs like it are popping up in the app stores, including Fit Brains (which is made by Rosetta Stone), BrainHQ, and Elevate. Today, Lumosity is one of the top apps to exercise your brain with 50 million members, but it's not alone. The idea became more mainstream in 2005, when Nintendo developed the game Brain Age for the Nintendo DS handheld console. Brain training is hardly new programs designed to exercise your mental abilities date back to the early 2000s. ![]() ![]() Additionally, you can monitor how changes in your mechanics affect your swing performance.ĭisclaimer: Weather-related damage (wind, snow, etc.) to golf cage poles is not covered or considered a defect.

During dialysis, fluid retention more than the maximum amount may lead to symptoms of heart failure risking the patient’s life. Patients suffering from chronic kidney disease are more prone to hyponatremia as their kidneys are already weak making it even more difficult in handling surplus liquids. Hyponatremia is the medical term used for such a condition. When left unattended, it can turn serious, or even lead to death in worst-case scenarios.įluid overload, aka, hypervolemia, makes it difficult for the kidneys to function normally, resulting in retention of excessive water thereby diluting the blood’s salt content. Undergoing dialysis or not, do not turn a blind eye to any such signs as overhydration. Apart from which, signs of headache, nausea, fatigue, confusion and restlessness are seen when the condition is relatively severe. Maintaining optimal blood pressure is another challenge faced by these patients in addition to shortness of breath and other heart problems. Overhydration among dialysis patients can cause edema where your feet, ankles and wrists swell up.

Most of the sounds we hear aren't simple, uniform waves. ![]() For example, a string vibrating at 440 Hz (cycles per second) generates a sound wave with a wavelength of approximately 2.5 feet (~80 cm) that we call A4 (the A just above middle C).īut pure tones are rare in practice. The vibrating strings create (acoustically or electronically) variations in air pressure - sound waves - that our ears interpret as sound.Ī sound wave with a specific wavelength (an oscillation at a specific frequency) creates a pure tone. The spectrogram is indicates the intensity of individual frequencies in the input signal.Īs you know, your guitar generates sound from the vibrations of the strings. They can be used to get a better sense of how FATpick is hearing the sound of your instrument. These add a bit of flair, but they aren't just eye-candy. For example, E2 (the note generated by the open 6th string in a standard guitar tuning) has frequency of approximately 82 Hz and middle C (C3) has frequency around 262 Hz.īelow the primary tuner gauge you will find a couple of other visualizations of the audio signal. The exact frequency of the detected pitch is displayed below the gauge, in Hz. Since natural fluctuations can make it difficult to keep the needle perfectly centered at all times, anything in the center region of the gauge might be considered "in tune", but try to get the needle as close to vertical as you can. When slightly sharp (above the expected frequency) the needle will point to the right. When the current frequency is slightly flat (below the expected value) the needle will point to the left of center. The needle will hover near the center of the gauge when the detected pitch is close to the expected frequency. The needle indicates how close the pitch is to the exact frequency of the detected note. This is the name of the note that is closest to the primary pitch currently detected in the input signal. The detected note (or more accurately, pitch class) is displayed at the top of the gauge, as one of the 12 notes of the chromatic scale (C, C#/Db, D, D#/Eb, E, F, F#/Gb, G, G#/Ab, A, A#/Bb, B). The primary component of the interface is a gauge similar to what you might find on a tuner guitar pedal or other electronic tuner. The tuner provides a graphical representation of the detected pitch and related information about the audio signal picked up by the microphone (or other input device). |
