IPad (7th Generation)
The iPad 10.2-inch (officially iPad (7th generation)) is a tablet computer developed and marketed by Apple Inc. It features a 10.2-inch Retina display and is powered by the Apple A10 Fusion processor. It is the successor to the 9.7-inch 6th-generation iPad. The device was revealed on September 10, 2019, and released on September 25, 2019. It has support for the first generation Apple Pencil and has a smart keyboard connector. It is targeted towards the budget and educational markets. Unlike previous iPad models, which have a 9.7-inch display, the device is the first in the entry-level iPad lineup to feature a larger 10.2-inch display size. Its successor, the eighth-generation iPad, was revealed on September 15, 2020, and it has replaced this iPad. History Rumors centering around a successor to the 2018 iPad began to surface in the first half of 2019, when seven iPad models were registered on the Eurasian Economic Commission, a database known for providing hints about upcom ...

IPad (5th Generation)
The iPad 9.7-inch (officially iPad (5th generation)) is a tablet computer designed, developed, and marketed by Apple Inc. After its announcement on March 21, 2017, conflicting naming conventions spawned a number of different names, including "seventh-generation iPad" or "iPad (2017)". It is the five years core iPad tablet successor to the iPad (4th generation) where the 2013 iPad Air was released as the first iPad to be exclusive on the iPad Air lineup instead. Unlike the iPad Air 2, this iPad does not have a fully laminated display, and also lacks an anti-reflective coating. On March 27, 2018, Apple announced its successor, the sixth-generation iPad. This also marked the discontinuation of the 2017 iPad. History This iPad model was announced by Apple on March 24, 2017 in a press release. There has been confusion around its naming, being referred to as just "iPad" in marketing, but called the "fifth-generation iPad" in official statements and specifications sheets, a tit ...

Low-key Lighting
Low-key lighting is a style of lighting for photography, film or television. It is a necessary element in creating a chiaroscuro effect. Traditional photographic lighting (three-point lighting) uses a key light, a fill light and a back light for illumination. Low-key lighting often uses only a key light, optionally controlled with a fill light or a simple reflector. Low key light accentuates the contours of the subject by throwing areas into shade while a fill light or reflector may illuminate the shadow areas to control contrast. The relative strength of key-to-fill, known as the lighting ratio, can be measured using a light meter. Low key lighting has a higher lighting ratio, e.g., 8:1, than high-key lighting, which can approach 1:1. The term "low key" is also used in cinematography and photography to refer to any scene with a high lighting ratio, especially if there is a predominance of shadowy areas. It tends to heighten the sense of alienation felt by the viewer, hence ...

Tablet Computer
A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, do what other personal computers do, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only differences being that tablets are relatively larger than smartphones, with screens or larger, measured diagonally, and may not support access to a cellular network. Unlike laptops which have traditionally run off operating systems usually designed for desktops, tablets usually run mobile operating systems, alongside smartphones. The touchscreen display is operated by Gesture recognition, gestures executed by finger or digital pen (stylus), instead of the Computer mouse, mouse, touchpad, and Keyboard (computing), keyboard of larger computers. Portable computers can be classifie ...

IR Filter
Infrared cut-off filters, sometimes called IR filters or heat-absorbing filters, are designed to reflect or block near-infrared wavelengths while passing visible light. They are often used in devices with bright incandescent light bulbs (such as slide and overhead projectors) to prevent unwanted heating. There are also filters which are used in solid state ( CCD or CMOS) video cameras to block IR due to the high sensitivity of many camera sensors to near-infrared light. These filters typically have a blue hue to them as they also sometimes block some of the light from the longer red wavelengths. IR transmitting/passing filters in photography In contrast to the naming convention of optical filters where the name of the filter denotes the wavelengths that are blocked, and in line with the convention for air filters and oil filters, photographic filters are named for the color of light they ''pass''. Thus a blue filter makes the picture look blue. A ''blue filter'' marginally allo ...

ISight
iSight is a brand name used by Apple Inc. to refer to cameras on various devices. The name was originally used for the external iSight webcam, which retailed for US$149, connected to a computer via a FireWire cable, and came with a set of mounts to place it atop any then current Apple display, laptop computer, all-in-one desktop computer, or flat surface. Apple introduced iSight at the 2003 Worldwide Developers Conference, and It was intended to be used with iChat AV, Apple's video-conferencing client. iMovie (version 4 and later) could also be used to capture video from the device. In April 2005, Apple released a firmware update for the iSight to improve audio performance. As of October 13, 2008, the external iSight was no longer for sale in the Apple online store or in retail locations. Meanwhile, Apple began using the term to refer to the camera built into Apple's iMac, MacBook, MacBook Air, and MacBook Pro computers, Thunderbolt Display, and Cinema Display. In November 2 ...

Barometer
A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries. Barometers and pressure altimeters (the most basic and common type of altimeter) are essentially the same instrument, but used for different purposes. An altimeter is intended to be used at different levels matching the corresponding atmospheric pressure to the altitude, while a barometer is kept at the same level and measures subtle pressure changes caused by weather and elements of weather. The average atmospheric pressure on the earth's surface varies between 940 and 1040 hPa (mbar). The average atmospheric pressure at sea level is 1013 hPa (mbar). Etymology The word ''barometer'' is derived from the Ancient Greek (), meaning "weight", and (), meaning "measure ...

Fingerprint Reader
Fingerprint scanners are security systems of biometrics. They are used in police stations, security industries, smartphones, and other mobile devices. Function Everyone has patterns of friction ridges on their fingers, and it is this pattern that is called the fingerprint. Fingerprints are uniquely detailed, durable over an individual's lifetime, and difficult to alter. Because there are countless combinations, fingerprints have become an ideal means of identification. Types of fingerprint scanners There are four types of fingerprint scanners: optical scanners, capacitance scanners, ultrasonic scanners, and thermal scanners. The basic function of every type of scanner is to obtain an image of a person's fingerprint and find a match for it in its database. The measure of the fingerprint image quality is in dots per inch (DPI). # Optical scanners take a visual image of the fingerprint using a digital camera. # Capacitive or CMOS scanners use capacitors and thus electrical current ...
