A cyber-physical production system (CPPS) is a manufacturing system in which physical production equipment is tightly coupled with computational elements through a digital twin, a core technology of Industry 4.0.
Cyber-security regulation
Cyber-security regulation is the body of laws, directives, and agency rules that require organizations to manage cyber risk and report incidents, developed in sector-specific and cross-sector waves since the late 1990s.
CyberArk
CyberArk is an Israeli identity security company specializing in privileged access management, founded near Tel Aviv in 1999 and acquired by Palo Alto Networks in 2026.
Cyberattack
A cyberattack, also called a computer attack, is an action via computer networks to disrupt systems, destroy data integrity, or steal information, including ransomware and phishing.
Cyberdeck
A cyberdeck is a custom-built portable computer, typically built around a single-board computer like a Raspberry Pi, with display, keyboard, battery, and handmade enclosure; the term comes from William Gibson's 1984 novel Neuromancer.
Cyberdyne
Cyberdyne Inc. is a Japanese robotics company in Tsukuba, founded in 2004 by professor Yoshiyuki Sankai, known for the HAL (Hybrid Assistive Limb) exoskeleton that assists human movement.
CyberForce (force-feedback glove)
CyberForce is a grounded force-feedback system attaching to the CyberGrasp exoskeleton and CyberGlove, developed by Immersion Corporation and sold by CyberGlove Systems for virtual reality simulation.
CyberGlove
The CyberGlove is an instrumented data glove that measures hand joint angles and transmits them to a computer, used in virtual reality and teleoperation research.
CyberHand
CyberHand is a cybernetic, anthropomorphic prosthetic hand developed at the Scuola Superiore Sant'Anna in Pisa as a research prototype for testing neural interfaces, control algorithms, and sensory feedback for amputees.
CyberKnife
The CyberKnife is a robotic radiosurgery system by Accuray that delivers focused radiation from many angles while tracking tumors in real time, treating targets anywhere in the body.
Cybernetics
Cybernetics is the transdisciplinary study of control, regulation, and communication in machines, living organisms, and social organizations, founded by Norbert Wiener, whose 1948 book gave the field its name.
Cybernetix
Cybernetix (Cybernétix S.A.) is a French robotics and remote-handling company founded in Marseille in 1985, known for the Maestro manipulator and now part of Technip Energies.
Cyberport

Cybersecurity and Infrastructure Security Agency
The Cybersecurity and Infrastructure Security Agency (CISA), created in 2018, is the lead US civilian cybersecurity agency under Homeland Security, protecting critical infrastructure, federal networks, and election security.
Cybersecurity Law of the People's Republic of China
The Cybersecurity Law of the People's Republic of China (中华人民共和国网络安全法, CSL) is China's principal network security statute, effective June 1, 2017, requiring data localization and imposing its largest fine on DiDi Global in 2022.
Cybersecurity Manufacturing Innovation Institute
The Cybersecurity Manufacturing Innovation Institute, or CyManII, is a Department of Energy manufacturing research institute launched in 2020 and led by the University of Texas at San Antonio.
Cybersecurity Maturity Model Certification
The Cybersecurity Maturity Model Certification (CMMC) is a Department of Defense program, established in 2020, that verifies defense contractors implement required cybersecurity safeguards before contract award.
Cyberspace
Cyberspace is the global domain of interdependent information systems infrastructure, including the Internet, a term coined by William Gibson in 1982 and now central to cybersecurity policy.
Cyborg beetle
A cyborg beetle is a living beetle fitted with an electronic backpack that lets a remote operator start, stop, and steer its flight by stimulating its brain and wing muscles.
Cyc
Cyc is an artificial intelligence project founded by Douglas Lenat in 1984 in Austin, Texas, aiming for human-like common-sense reasoning via a huge formal knowledge base of world knowledge.
Cycle detection
Cycle detection, also known as cycle finding, is the algorithmic problem of determining whether a graph contains a cycle and returning it, solved in linear time with depth-first search.
Cycle slip detection
Cycle slip detection is a GNSS data processing method that identifies abrupt integer-cycle jumps in carrier-phase measurements, usually from temporary loss of lock, keeping RTK and PPP positioning reliable.
Cycle tunnel
A cycle tunnel is a tunnel designed primarily for bicycle traffic, ranging from Rotterdam's Maastunnel of 1937–1942 to new Dutch openings in 2025 and 2026.
Cycle-accurate simulation
Cycle-accurate simulation is a hardware modeling technique that reproduces a digital system's behavior on every clock cycle, letting engineers run real system software against a hardware model before silicon exists.
Cycle-consistent generative adversarial network
A cycle-consistent generative adversarial network (CycleGAN) is a method for unpaired image-to-image translation, such as turning photos into paintings or horses into zebras, using a cycle-consistency loss.
Cyclecar
A cyclecar was a small, lightweight automobile built from about 1910 to the mid-1920s, typically from motorcycle parts, with over 100 makers in Britain and France by 1914.
CycleGAN
CycleGAN is a generative adversarial network framework for unpaired image-to-image translation, introduced by Jun-Yan Zhu and colleagues at ICCV 2017, using a cycle-consistency loss instead of paired training data.
Cyclic carbonate electrolytes
Cyclic carbonate electrolytes are lithium-ion battery electrolytes built on ethylene carbonate and propylene carbonate, whose ring structures dissolve salt and form the protective anode film.
