2. Inductive sensor - Wikipedia

   en.wikipedia.org/wiki/Inductive_sensor

   An inductive sensor is a device that uses the principle of electromagnetic induction to detect or measure objects. An inductor develops a magnetic field when an electric current flows through it; alternatively, a current will flow through a circuit containing an inductor when the magnetic field through it changes.

3. Near-field magnetic induction communication - Wikipedia

   en.wikipedia.org/wiki/Near-field_magnetic...

   The properties that make long range communication possible are a disadvantage for short range communication systems. The NFMI system uses a short range (less than 2 meters). The standard modulation schemes used in typical RF communications (amplitude modulation, phase modulation, and frequency modulation) can be used in near-field magnetic ...

4. Wireless power transfer - Wikipedia

   en.wikipedia.org/wiki/Wireless_power_transfer

   Resonant inductive coupling can achieve high efficiency at ranges of 4 to 10 times the coil diameter (D ant). [68] [69] [70] This is called "mid-range" transfer, [69] in contrast to the "short range" of nonresonant inductive transfer, which can achieve similar efficiencies only when the coils are adjacent. Another advantage is that resonant ...

5. Long-Range Reconnaissance and Observation System - Wikipedia

   en.wikipedia.org/wiki/Long-Range_Reconnaissance...

   Long-Range Reconnaissance and Observation System or LORROS is a sensor system developed by Elbit Systems to provide long-range daytime and night-time surveillance. The unit consists of Forward looking infrared (FLIR) and Charge-coupled device (CCD) image sensors. Optional components include eyesafe laser rangefinder, built-in compass and ...

6. Induction loop - Wikipedia

   en.wikipedia.org/wiki/Induction_loop

   An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire. Induction loops are used for transmission and reception of communication signals, or for detection of metal objects in metal detectors or vehicle presence ...

8. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect current sensor; the only difference is that this method uses the saturable inductor instead of the Hall-effect sensor in the air gap. Saturable inductor current sensor is based on the detection of an inductance change. The saturable inductor is ...
