Redmi
Redmi is a subsidiary company owned by the Chinese electronics company Xiaomi. It was first announced in July 2013 as a budget smartphone line, and became a separate sub-brand of Xiaomi in 2019 with entry-level and mid-range devices, while Xiaomi itself produces upper-range and flagship Xiaomi (formerly Mi) phones. Redmi phones use the Xiaomi's MIUI user interface on top of Android. Models are divided into the entry-level Redmi, the mid-range Redmi Note, and the high-end Redmi K. In addition, the unrelated ''Mi A'' Android One series is also positioned in the similar market segment with Redmi devices, despite being part of the upper-range Xiaomi Mi lineup. The most significant difference from other Xiaomi smartphones is that they use less-expensive components and thus have lower prices while retaining higher specifications. In August 2014, ''The Wall Street Journal'' reported that in the second quarter of the 2014 fiscal year, Xiaomi had a market share of 4% of smartphone ship ...

Form Factor (mobile Phones)
The form factor of a mobile phone is its size, shape, and style, as well as the layout and position of its major components. With one non-movable section Bar A bar (also known as a slab, block, candybar) phone takes the shape of a cuboid, usually with rounded corners and/or edges. The name is derived from the rough resemblance to a chocolate bar in size and shape. This form factor is widely used by a variety of manufacturers, such as Nokia and Sony Ericsson. Bar-type smartphones commonly have the screen and keypad on a single face. Sony had a well-known 'Mars Bar' phone model CM-H333 in 1993. Bar phones without a full keyboard tend to have a 3×4 numerical keypad; text is often generated on such systems using the Text on 9 keys algorithm. Keyboard bars These are variants of bars that have a full QWERTY keyboard on the front. While they are technically the same as a regular bar phone, the keyboard and all the buttons make them look significantly different. Devices like these we ...

Refresh Rate
The refresh rate (or "vertical refresh rate", "vertical scan rate", terminology originating with the cathode ray tubes) is the number of times per second that a raster-based display device displays a new image. This is independent from frame rate, which describes how many images are stored or generated every second by the device driving the display. On cathode ray tube (CRT) displays, higher refresh rates produce less flickering, thereby reducing eye strain. In other technologies such as liquid-crystal displays, the refresh rate affects only how often the image can potentially be updated. Non-raster displays may not have a characteristic refresh rate. Vector displays, for instance, do not trace the entire screen, only the actual lines comprising the displayed image, so refresh speed may differ by the size and complexity of the image data. For computer programs or telemetry, the term is sometimes applied to how frequently a datum is updated with a new external value from a ...

Compass
A compass is a device that shows the cardinal directions used for navigation and geographic orientation. It commonly consists of a magnetized needle or other element, such as a compass card or compass rose, which can pivot to align itself with North magnetic pole, magnetic north. Other methods may be used, including gyroscopes, magnetometers, and GPS receivers. Compasses often show angles in degrees: north corresponds to 0°, and the angles increase clockwise, so east is 90°, south is 180°, and west is 270°. These numbers allow the compass to show azimuths or bearing (angle), bearings which are commonly stated in degrees. If local magnetic declination, variation between magnetic north and true north is known, then direction of magnetic north also gives direction of true north. Among the Four Great Inventions, the magnetic compass was first invented as a device for divination as early as the history of science and technology in China, Chinese Han Dynasty (since c. 206 BC),#Li ...

Proximity Sensor
A proximity sensor is a sensor able to detect the presence of nearby objects without any physical contact. A proximity sensor often emits an electromagnetic field or a beam of electromagnetic radiation (infrared, for instance), and looks for changes in the 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 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 bearing. This is common in large steam turbines, compressors, and motors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 fligh ...

Fingerprint Scanner
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 curren ...

USB-C
USB-C (properly known as USB Type-C) is a 24-pin USB connector system with a rotationally symmetrical connector. The designation C refers only to the connector's physical configuration or form factor and should not be confused with the connector's specific capabilities, which are designated by its transfer specifications (such as USB 3.2). A notable feature of the USB-C connector is its ''reversibility''; a plug may be inserted into a receptacle in either orientation. The ''USB Type-C Specification 1.0'' was published by the USB Implementers Forum (USB-IF) and was finalized in August 2014. It was developed at roughly the same time as the USB 3.1 specification. In July 2016, it was adopted by the IEC as "IEC 62680-1-3". A device with a Type-C connector does not necessarily implement USB, USB Power Delivery, or any Alternate Mode: the Type-C connector is common to several technologies while mandating only a few of them. USB 3.2, released in September 2017, re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Random Access Memory
Random-access memory (RAM; ) is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. A random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks, CD-RWs, DVD-RWs and the older magnetic tapes and drum memory), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. RAM contains multiplexing and demultiplexing circuitry, to connect the data lines to the addressed storage for reading or writing the entry. Usually more than one bit of storage is accessed by the same address, and RAM devices often have multiple data lines and are said to be "8-bit" or "16-bit", etc. devices ...

LPDDR
Low-Power Double Data Rate (LPDDR), also known as LPDDR SDRAM, is a type of synchronous dynamic random-access memory that consumes less power and is targeted for mobile computers and devices such as mobile phones. Older variants are also known as Mobile DDR, and abbreviated as mDDR. Modern LPDDR SDRAM is distinct from DDR SDRAM, with various differences that make the technology more appropriate for the mobile application. LPDDR technology standards are developed independently of DDR standards, with LPDDR4X and even LPDDR5 for example being implemented prior to DDR5 SDRAM and offering far higher data rates than DDR4 SDRAM. Bus width In contrast with standard SDRAM, used in stationary devices and laptops and usually connected over a 64-bit wide memory bus, LPDDR also permits 16- or 32-bit wide channels. The "E" versions mark enhanced versions of the specifications. They formalize overclocking the memory array up to 266 MHz for a 33% performance boost. Memory modules impl ...
