  2. Mechanically isolated system - Wikipedia

    en.wikipedia.org/wiki/Mechanically_isolated_system

    For a simple system, mechanical isolation is equivalent to a state of constant volume and any process which occurs in such a simple system is said to be isochoric. [1] The opposite of a mechanically isolated system is a mechanically open system, [citation needed] which allows the transfer of mechanical energy. For a simple system, a ...

  3. Isolated system - Wikipedia

    en.wikipedia.org/wiki/Isolated_system

    The concept of an isolated system can serve as a useful model approximating many real-world situations. It is an acceptable idealization used in constructing mathematical models of certain natural phenomena ; e.g., the planets in the Solar System , and the proton and electron in a hydrogen atom are often treated as isolated systems.

  4. Galvanic isolation - Wikipedia

    en.wikipedia.org/wiki/Galvanic_isolation

    Although isolated power is usually done with a transformer, it can also be done with capacitors and a H-bridge driver when the constraints of size and cost favor capacitors. [4] Where capacitors are used for isolation from power supply circuits, they may carry special ratings to indicate they cannot fail in a short-circuit, possibly connecting ...

  5. Vibration isolation - Wikipedia

    en.wikipedia.org/wiki/Vibration_isolation

    Vibration isolation is the prevention of transmission of vibration from one component of a system to others parts of the same system, as in buildings or mechanical systems. [1] Vibration is undesirable in many domains, primarily engineered systems and habitable spaces, and methods have been developed to prevent the transfer of vibration to such ...

  6. Wireless power transfer - Wikipedia

    en.wikipedia.org/wiki/Wireless_power_transfer

    An electrodynamic wireless power transfer (EWPT) system utilizes a receiver with a mechanically resonating or rotating permanent magnet. [ 96 ] [ 97 ] When subjected to a time-varying magnetic field, the mechanical motion of the resonating magnet is converted into electricity by one or more electromechanical transduction schemes (e.g ...

  7. Multiple Access with Collision Avoidance for Wireless

    en.wikipedia.org/wiki/Multiple_Access_with...

    Source: [1] Node D is unaware of the ongoing data transfer between node A and node B. Node D has data to send to node C, which is in the transmission range of node B. D initiates the process by sending an RTS frame to node C. Node C has already deferred its transmission until the completion of the current data transfer between node A and node B (to avoid co-channel interference at node B).

  9. Air interface - Wikipedia

    en.wikipedia.org/wiki/Air_interface

    In cellular telephone communications, the air interface is the radio-frequency portion of the circuit between the cellular phone set or wireless modem (usually portable or mobile) and the active base station. As a subscriber moves from one cell to another in the system, the active base station changes periodically.
