The encyclopedia explains the major technical terms used to describe the technologies for the future markets of today, tomorrow and beyond. From A as in app to M as in MEMS right through to Z as in ZigBee.

Data mining

Processing large data sets (big data), whereby individual data parts are connected to one another, bringing about new information.

Data protection

Protection of the sensitive interests and privacy of natural persons and legal entities against misuse by electronic media.

Data security

Laws and technical measures aimed at preventing the unauthorised storage, processing and distribution of sensitive data.

Deep learning

Sub-area of machine learning in which deep neural networks are used. Whilst machine learning works using linear algorithms, the algorithms in deep learning are hierarchical, organised according to increasing complexity.

Digital twin

A digital representation of a real entity or system. The implementation of a digital twin is an encapsulated software object or model that mirrors a unique physical object, process, organisation, person or other abstraction.


At the core of a Digital Light Processing (DLP) system is a chip carrying more than eight million micro-mirrors. Individually controlled, the micro-mirrors are tilted either towards a light source (ON) or away from it (OFF). This generates a bright or dark pixel on the viewed object. A a result, a light pattern can be projected onto a scene which is likewise captured by a camera. A 3D pixel cloud can be calculated from the distortion of the pattern caused by the object.


WLAN variant for ad-hoc communication in the 5-GHz frequency band of IEEE 802.11p. DSRC is used in conjunction with V2X, and is normally referred to as ITS-G5 in Europe.
