2. United States Space Surveillance Network - Wikipedia

   en.wikipedia.org/wiki/United_States_Space...

   The United States Department of Defense (DoD) has maintained a database of satellite states since the launch of the first Sputnik in 1957, known as the Space Object Catalog, or simply the Space Catalog. These satellite states are regularly updated with observations from the Space Surveillance Network, a globally distributed network of ...

5. MEMS magnetic field sensor - Wikipedia

   en.wikipedia.org/wiki/MEMS_magnetic_field_sensor

   A MEMS magnetic field sensor is a small-scale microelectromechanical systems (MEMS) device for detecting and measuring magnetic fields (magnetometer). Many of these operate by detecting effects of the Lorentz force : a change in voltage or resonant frequency may be measured electronically, or a mechanical displacement may be measured optically.

6. Quantum sensor - Wikipedia

   en.wikipedia.org/wiki/Quantum_sensor

   In solid-state physics, a quantum sensor is a quantum device that responds to a stimulus. Usually this refers to a sensor, which has quantized energy levels, uses quantum coherence or entanglement to improve measurements beyond what can be done with classical sensors. [4] There are four criteria for solid-state quantum sensors: [4]

7. Oxygen sensor - Wikipedia

   en.wikipedia.org/wiki/Oxygen_sensor

   An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. [1] It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter Bauman. [1]
