For an example capacitive sense IC, Texas Instruments's FDC1004 applies a 25-kHz step waveform to charge up an electrode, and after a defined amount of time, converts the analog voltage representing that charge into a digital value of capacitance using a built-in analog-to-digital converter (ADC).
The device does not require the use of a traditional PC mouse or keyboard, and generally does not require training or foreknowledge to operate. ... Weight: 198 lbs ...
[7] [8] A low-resolution "mostly digital" N-channel MOSFET (NMOS) imager with intra-pixel amplification, for an optical mouse application, was demonstrated by Richard F. Lyon in 1981. [9] Another type of image sensor technology that is related to the APS is the hybrid infrared focal plane array (IRFPA), [ 1 ] designed to operate at cryogenic ...
Different types of light sensors. A sensor is a device that produces an output signal for the purpose of detecting 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.
The first-generation Magic Mouse was released on October 20, 2009, and introduced multi-touch functionality to a computer mouse. [1] [2] Taking after the iPhone, iPod Touch, and multi-touch MacBook trackpads, the Magic Mouse allows the use of multi-touch gestures and inertia scrolling across the surface of the mouse, designed for use with macOS.

The factor–label method can convert only unit quantities for which the units are in a linear relationship intersecting at 0 (ratio scale in Stevens's typology). Most conversions fit this paradigm. An example for which it cannot be used is the conversion between the Celsius scale and the Kelvin scale (or the Fahrenheit scale). Between degrees ...
