Dolby Atmos
Dolby Atmos is a surround sound technology developed by Dolby Laboratories. It expands on existing surround sound systems by adding height channels, allowing sounds to be interpreted as three-dimensional objects with neither horizontal, nor vertical limitation. Following the release of Atmos for the cinema market, a variety of consumer technologies have been released under the Atmos brand, using in-ceiling and up-firing speakers. History The first Dolby Atmos installation was in the El Capitan Theater in Los Angeles, for the premiere of ''Brave'' in June 2012. Throughout 2012, it saw a limited release of about 25 installations worldwide, with an increase to 300 locations in 2013. As of October 2022, there were over 10,000 Dolby Atmos enabled cinema screens, installed, or committed to. Dolby Atmos has also been adapted to a home theater format and is the audio component of Dolby Cinema. Most electronic devices since 2016, as well as smartphones after 2017, have been enabled fo ...

AMOLED
AMOLED (active-matrix organic light-emitting diode, ) is a type of OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels. Since 2007, AMOLED technology has been used in mobile phones, media players, TVs and digital cameras, and it has continued to make progress toward low-power, low-cost, high resolution and large size (for example, 88-inch and 8K resolution) applications. Design An AMOLED display consists of an active matrix of OLED pixels generating light (luminescence) upon electrical activation that have been deposited or integrated onto a thin-film transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel. Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger the luminescence), wit ...

Near-field Communication
Near-field communication (NFC) is a set of communication protocols that enables communication between two electronic devices over a distance of 4 cm (1 in) or less. NFC offers a low-speed connection through a simple setup that can be used to bootstrap more-capable wireless connections. Like other " proximity card" technologies, NFC is based on inductive coupling between two so-called antennas present on NFC-enabled devices—for example a smartphone and a printer—communicating in one or both directions, using a frequency of 13.56 MHz in the globally available unlicensed radio frequency ISM band using the ISO/IEC 18000-3 air interface standard at data rates ranging from 106 to 424 kbit/s. The standards were provided by the NFC Forum. The forum was responsible for promoting the technology and setting standards and certifies device compliance. Secure communications are available by applying encryption algorithms as is done for credit cards and if they fit the crit ...

Gorilla Glass
Gorilla Glass is a brand of chemically strengthened glass developed and manufactured by Corning, now in its seventh generation. Designed to be thin, light and damage-resistant, the glass gains its surface strength, ability to contain flaws, and crack-resistance by being immersed in a hot, potassium-salt, ion-exchange bath. As a brand, Gorilla Glass is specific to Corning, but close equivalents exist, including AGC Inc.'s Dragontrail and Schott AG's Xensation. The alkali- aluminosilicate sheet glass is used primarily as cover glass for portable electronic devices, including mobile phones, smartwatches, portable media players, portable computer displays, and television screens. It is manufactured in Harrodsburg, Kentucky; in Asan, South Korea; and in Taiwan. In October 2017, some five billion devices globally contained Gorilla Glass. While dominating its market, Gorilla Glass faces varying competition from rivals such as Dragontrail and synthetic sapphire. Background and de ...

Hall Sensor
In architecture, a hall is a relatively large space enclosed by a roof and walls. In the Iron Age and early Middle Ages in northern Europe, a mead hall was where a lord and his retainers ate and also slept. Later in the Middle Ages, the great hall was the largest room in castles and large houses, and where the servants usually slept. As more complex house plans developed, the hall remained a large room for dancing and large feasts, often still with servants sleeping there. It was usually immediately inside the main door. In modern British houses, an entrance hall next to the front door remains an indispensable feature, even if it is essentially merely a corridor. Today, the (entrance) hall of a house is the space next to the front door or vestibule leading to the rooms directly and/or indirectly. Where the hall inside the front door of a house is elongated, it may be called a passage, corridor (from Spanish ''corredor'' used in El Escorial and 100 years later in Castle Ho ...

Accelerometer
An accelerometer is a tool that measures proper acceleration. Proper acceleration is the acceleration (the rate of change of velocity) of a body in its own instantaneous rest frame; this is different from coordinate acceleration, which is acceleration in a fixed coordinate system. For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth's gravity, straight upwards (by definition) of g ≈ 9.81 m/s2. By contrast, accelerometers in free fall (falling toward the center of the Earth at a rate of about 9.81 m/s2) will measure zero. Accelerometers have many uses in industry and science. Highly sensitive accelerometers are used in inertial navigation systems for aircraft and missiles. Vibration in rotating machines is monitored by accelerometers. They are used in tablet computers and digital cameras so that images on screens are always displayed upright. In unmanned aerial vehicles, accelerometers help to stabilise fli ...

Exynos
Exynos, formerly Hummingbird (), is a series of ARM-based system-on-chips developed by Samsung Electronics' System LSI division and manufactured by Samsung Foundry. It is a continuation of Samsung's earlier S3C, S5L and S5P line of SoCs. Exynos is mostly based on the ARM Cortex cores with the exception of some high end SoCs which featured Samsung's proprietary "M" series core design; though from 2021 onwards even the flagship high-end SoC's will be featuring ARM Cortex cores. History In 2010, Samsung launched the Hummingbird S5PC110 (now Exynos 3 Single) in its Samsung Galaxy S smartphone, which featured a licensed ARM Cortex-A8 CPU. This ARM Cortex-A8 was code-named Hummingbird. It was developed in partnership with Intrinsity using their FastCore and Fast14 technology. In early 2011, Samsung first launched the Exynos 4210 SoC in its Samsung Galaxy S II mobile smartphone. The driver code for the Exynos 4210 was made available in the Linux kernel and support was add ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
