IPad (7th Generation)
The iPad (7th generation) (also referred to as the iPad 10.2-inch) is a tablet computer developed and marketed by Apple Inc. It featured a Retina display and is powered by the Apple A10 Fusion processor. It was the successor to the 6th-generation iPad. The device was revealed on September 10, 2019, and released on September 25, 2019. The device had support for the first generation Apple Pencil and a smart keyboard connector and was targeted towards the budget and educational markets. Unlike previous iPad models, which had a display, the device was the first in the entry-level iPad lineup to feature a larger display size. Its successor, the eighth-generation iPad, was revealed on September 15, 2020. Because the A10 Fusion processor did not have any neural engine cores, this was the last currently supported iPad without a neural engine. Following the announcement at Apple's WWDC 2025, the seventh-generation iPad no longer supports the major software update starting wit ...

IPad (5th Generation)
The iPad (5th generation) (also referred to as the iPad 9.7-inch) is a tablet computer developed and marketed by Apple Inc. After its announcement on March 21, 2017, conflicting naming conventions spawned a number of different names, including "fifth-generation iPad" or "iPad (2017)". The device was released five years after the previous fourth-generation iPad, as the iPad Air was released in 2013 as the successor to the iPad lineup. The iPad Air lineup later continued as a separate, higher-end device, while the iPad was positioned as an entry-level model. 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. 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 officia ...

Proximity Sensor
A proximity sensor (often simply prox) is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an Electromagnetic field, electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the electric field, field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor targets demand different sensors. For example, a capacitive proximity sensor or photoelectric sensor might be suitable for a plastic target; an inductive sensor, inductive proximity sensor always requires a metal target. Proximity sensors can have a high reliability and long functional life because of the absence of mechanical parts and lack of physical contact between the sensor and the sensed object. Proximity sensors are also used in machine vibration monitoring to measure the variation in distance between a shaft and its support beari ...

Retina Display
Retina display is a branded series of LCDs and OLED displays by Apple Inc. that have a higher pixel density than their traditional displays. Apple has registered the term "Retina" as a trademark with regard to computers and mobile devices with the United States Patent and Trademark Office and Canadian Intellectual Property Office. Claims priority filing date with respect to prior application in Jamaica. Also cites prior application in Jamaica. The applications were approved in 2012 and 2014, respectively. The Retina display debuted in 2010 with the iPhone 4 and the iPod Touch (4th generation), and later the iPad (3rd generation) where each screen pixel of the iPhone 3GS, iPod Touch (3rd generation), and iPad 2 was replaced by four smaller pixels, and the user interface scaled up to fill in the extra pixels. Apple calls this mode ''HiDPI mode''. In simpler words, it is one logical pixel that corresponds to four physical pixels. The scale factor is tripled for devices with even ...

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, have similar capabilities, 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 classified according ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ISight
iSight is a brand name used by Apple Inc. to refer to webcams 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 round 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 Novem ...

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 Trough (meteorology), troughs, pressure systems and weather front, 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 ''wikt:barometer, barometer'' is derived from the Ancient Gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fingerprint Reader
Fingerprint scanners are a type of biometric security device that identify an individual by identifying the structure of their fingerprints. They are used in police stations, security industries, smartphones, and other mobile devices. Fingerprints People have patterns of friction ridges on their fingers, these patterns are called the fingerprints. Fingerprints are uniquely detailed, durable over an individual's lifetime, and difficult to alter. Due to the unique combinations, fingerprints have become an ideal means of identification. Types of fingerprint scanners There are four types of fingerprint scanners: # Optical scanners take a visual image of the fingerprint using a digital camera. # Capacitive or CMOS scanners use capacitors and thus electric current to form an image of the fingerprint. This type of scanner tends to excel in terms of precision. # Ultrasonic fingerprint scanners use high frequency sound waves to penetrate the epidermal (outer) layer of the skin. # T ...

Touch ID
Touch ID is an electronic fingerprint recognition feature designed and released by Apple Inc. History In 2012, Apple acquired AuthenTec, a company focused on fingerprint-reading and identification management software, for $356 million. The acquisition led commentators to expect a fingerprint reading feature. Following leaks and speculation in early September the next year, the iPhone 5s was unveiled on September 10, 2013, and was the first phone on a major US carrier to feature the technology. Apple's Vice president, Vice President of Marketing, Phil Schiller, announced the feature at Apple's iPhone media event and spent several minutes (the major portion of the conference) discussing the feature. Wells Fargo analyst Maynard Um predicted on September 4, 2013, that a fingerprint sensor in the iPhone 5s would help mobile commerce and boost adoption in the corporate environment. Um said,"As consumers increasingly rely on mobile devices to transact and store personal data, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
