Logitech PowerPlay
Logitech PowerPlay is a mousepad underlay which can charge compatible mice both at rest and while they are in use. It connects to the computer via USB and, on the pad side, features a control module which a compatible mouse can connect to via the proprietary Lightspeed protocol. Mice need to support inserting Logitech's Powercore module to capture the electromagnetic energy. The control module has a lit-up logo whose colors can be changed using software and a light to indicate whether the mouse is connected. History According to Logitech, there were neither wireless chargers that were thin enough to fit into the mousepad nor chargers that could cover the necessary surface area when development started on PowerPlay. The 2.5 W provided by a USB port was found not to be sufficient to meet the power demand of the mouse when the field needs to be projected across the entire area of the mousepad, necessitating changes to the mouse and its firmware to reduce its consumption.

Logitech
Logitech International S.A. ( ) is a Swiss multinational manufacturer of computer peripherals and software. Headquartered in Lausanne, Switzerland, the company has offices throughout Europe, Asia, Oceania, and the Americas. It is a component of the Swiss Market Index, and is listed on the Nasdaq. The company develops and markets personal peripherals for PC navigation, video communication and collaboration, music and smart homes. This includes products like keyboards, mice, tablet accessories, headphones and headsets, webcams, Bluetooth speakers, universal remotes and more. Its name is derived from ''logiciel'' (the French word for software) and 'tech'. History Logitech was founded in Apples, Vaud, Switzerland, in 1981, by Daniel "Bobo" Borel, Pierluigi Zappacosta, and former Olivetti engineer Giacomo Marini. Swiss-born Borel and Italian-born Zappacosta had met in California while taking electrical engineering classes in the late 1970s at Stanford University, under p ...

Tweakers
Tweakers (formerly called Tweakers.net) is a Dutch technology website featuring news and information about hardware, software, games and the Internet. The name is derived from the verb "tweaking", which is a word used to refer to optimisation of hardware. Tweakers has grown substantially since its founding in 1998. As of 2023, it publishes news, reviews, features and video reports about technology subjects, with a strong focus on the Netherlands and Belgium. Tweakers has more features for computer enthusiasts, such as reviews, bi-monthly Best Buy guides, a classifieds section for jobs and used hardware, the Pricewatch and the Shop Survey, among others. While the majority of the reviews are written in Dutch, several articles covering non-standard topics are translated into English. Tweakers has more than 1.000.000 members and its forum has over 29 million posts. It has won several awards, including "(Dutch) website of the year" in 2009, 2010, 2011, 2012, 2013 and 2014.

Mousepad
A mousepad or mousemat is a surface for placing and moving a computer mouse. A mousepad enhances the usability of the mouse compared to using a mouse directly on a table by providing a surface to allow it to measure movement accurately and without jitter. Some mousepads increase ergonomics by providing a padded wrist rest. History During a 1967 presentation by Douglas Engelbart marking the public debut of a mouse,, final video Engelbart used a control console designed by Matt P. Brown of Herman Miller that included a keyboard and an inset portion used as a support area for the mouse. According to Kelley and also stated by Alex Pang, Kelley designed the first mousepad a year later, in 1969. Details of a mousepad designed by Armando M. Fernandez were published in the Xerox Disclosure Journal in 1979 with the description: By 1982, most users of the Xerox ball mouse were using special pads to increase the friction of the ball in the mouse. The first commercial manufacturer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Mouse
A computer mouse (plural mice; also mouses) is a hand-held pointing device that detects Plane (mathematics), two-dimensional motion relative to a surface. This motion is typically translated into the motion of the Cursor (user interface)#Pointer, pointer (called a cursor) on a computer monitor, display, which allows a smooth control of the graphical user interface of a computer. The first public demonstration of a mouse controlling a computer system was done by Doug Engelbart in 1968 as part of the Mother of All Demos. Mice originally used two separate wheels to directly track movement across a surface: one in the x-dimension and one in the Y. Later, the standard design shifted to use a ball rolling on a surface to detect motion, in turn connected to internal rollers. Most modern mice use optical mouse, optical movement detection with no moving parts. Though originally all mice were connected to a computer by a cable, many modern mice are cordless, relying on short-range rad ...

Watt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...

Polycarbonate
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate ester, carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, toughness, tough materials, and some grades are optically transparent. They are easily worked, injection molding, molded, and thermoforming, thermoformed. Because of these properties, polycarbonates find many applications. Polycarbonates do not have a unique resin identification code, resin identification code (RIC) and are identified as "Other", 7 on the RIC list. Products made from polycarbonate can contain the precursor monomer bisphenol A (BPA). Structure Carbonate esters have planar OC(OC)2 cores, which confer rigidity. The unique O=C bond is short (1.173 Å in the depicted example), while the C-O bonds are more ether-like (the bond distances of 1.326 Å for the example depicted). Polycarbonates received their name because they are polymers containing carbonate ester, carbonate groups (−O−( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Peripherals
A peripheral device, or simply peripheral, is an auxiliary hardware device that a computer uses to transfer information externally. A peripheral is a hardware component that is accessible to and controlled by a computer but is not a core component of the computer. A peripheral can be categorized based on the direction in which information flows relative to the computer: * The computer receives data from an '' input device''; examples: mouse, keyboard, scanner, game controller, microphone and webcam * The computer sends data to an '' output device''; examples: monitor, printer, headphones, and speakers * The computer sends and receives data via an ''input/output device''; examples: storage device (such as disk drive, solid-state drive, USB flash drive, memory card and tape drive), modem, router, gateway and network adapter Many modern electronic devices, such as Internet-enabled digital watches, video game consoles, smartphones, and tablet computers, have ...
