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.
Charging docks supply power and do not include a host device or data pins, allowing any capable USB device to charge or operate from a standard USB cable. Charging cables provide power connections, but not data. In a charge-only cable, the data wires are shorted at the device end, otherwise, the device may reject the charger as unsuitable.
English: Diagram of a mechanical mouse. Pulling the mouse turns the ball. X and Y rollers grip the ball and transfer movement. Optical encoding disks include light holes. Infrared LEDs shine through the disks. Sensors gather light pulses to convert to X and Y velocities.
The Jiffy is the amount of time light takes to travel one femtometre (about the diameter of a nucleon). The Planck time is the time that light takes to travel one Planck length. The TU (for time unit) is a unit of time defined as 1024 μs for use in engineering. The svedberg is a time unit used for sedimentation rates (usually
Shorted or near-shorted data lanes with less than 200 Ω of resistance across the D+ and D− terminals signify a dedicated charging port (DCP) with indefinite charging rates. [ 102 ] [ 103 ] In addition to standard USB, there is a proprietary high-powered system known as PoweredUSB , developed in the 1990s, and mainly used in point-of-sale ...
A computer mouse with the most common features: two buttons (left and right) and a scroll wheel (which can also function as a button when pressed inwards) A typical wireless computer mouse. A computer mouse (plural mice, also mouses) [nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface
Minute ventilation (or respiratory minute volume or minute volume) is the volume of gas inhaled (inhaled minute volume) or exhaled (exhaled minute volume) from a person's lungs per minute. It is an important parameter in respiratory medicine due to its relationship with blood carbon dioxide levels. It can be measured with devices such as a ...
The purpose of the diameter credit control application is to provide a framework for real-time charging, primarily meant for the communication between gateways/control-points and the back-end account/balance systems (typically an Online Charging System). The application specifies methods for: Quota management (Reserve, Reauthorize, Abandon)
