Liquid Contact Indicator
A liquid contact indicator (LCI) is a small indicator that turns from white into another color, typically red, after contact with water. These indicators are small adhesives that are placed on several points within electronic devices such as laptops and smartphones. In case of a defective device, service personnel can check whether the device might have suffered from contact with water, to protect from warranty fraud. Liquid contact indicators are also known by other names such as water damage tape, water damage sticker, water contact indicator tape, liquid submersion indicator. Purpose The main purpose of the liquid contact indicator is to have a lead to the cause of a defect in electronic devices. The LCI can also be used to avoid discussions about liability and warranty, if it is triggered. Still there can be reasons for doubt. *Longer, but not extreme exposure of a device in a humid environment, can trigger a LCI. *In theory water can reach the LCI(s), but still the electron ...

Dock Connector
A dock connector is a connector used to attach a mobile electronic device simultaneously to multiple external resources. The dock connector will typically carry a variety of signals and power, through a single connector, to simplify the process of docking the mobile device. A dock connector may be embedded in a mechanical fixture used to support or align the mobile device or may be at the end of a cable. The dock connector was originally associated with laptops, but other mobile devices use the concept. Laptops Classic docking connectors for laptop computers are usually embedded into a mechanical docking station and port replicator devices that supports and aligns the laptop and sports various single-function ports and a power source that are aggregated into the docking connector. Docking connectors would carry interfaces such as keyboard, serial, parallel, and video ports from the laptop and supply power to it. Current docking connection options usually can be defined as ...

Samsung Galaxy S III
The Samsung Galaxy S III (or Galaxy S3) is an Android smartphone designed, developed, and marketed by Samsung Electronics. Launched in 2012, it had sold more than 80 million units overall, making it the most sold phone in the S series. It is the third smartphone in the Samsung Galaxy S series. It has additional software features, expanded hardware, and a redesigned physique from its predecessor, the Samsung Galaxy S II, released the previous year. The "S III" employs an intelligent personal assistant ( S Voice), eye-tracking ability, and increased storage. Although a wireless charging option was announced, it never came to fruition. However, there are third party kits which add support for Qi wireless charging. Depending on country, the smartphone comes with different processors and RAM capacity, and 4G LTE support. The device was launched with Android 4.0.4 "Ice Cream Sandwich", was updated to Android 4.3 "Jelly Bean", and can be updated to Android 4.4. ...

Sensors
A sensor is a device that produces an output signal for the purpose of sensing a physical phenomenon. In the broadest definition, a sensor is a device, module, machine, or subsystem that detects events or changes in its environment and sends the information to other electronics, frequently a computer processor. Sensors are always used with other electronics. Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base, and in innumerable applications of which most people are never aware. With advances in micromachinery and easy-to-use microcontroller platforms, the uses of sensors have expanded beyond the traditional fields of temperature, pressure and flow measurement, for example into MARG sensors. Analog sensors such as potentiometers and force-sensing resistors are still widely used. Their applications include manufacturing and machinery, airplanes and aerospace, cars, medicine, robot ...

Mobile Phones
A mobile phone, cellular phone, cell phone, cellphone, handphone, hand phone or pocket phone, sometimes shortened to simply mobile, cell, or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called ''cellular telephones'' or ''cell phones'' in North America. In addition to telephony, digital mobile phones ( 2G) support a variety of other services, such as text messaging, multimedia messagIng, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, video games and digital photography. Mobile phones offering only those capabilities are known as featur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
