  2. Isolator (microwave) - Wikipedia

    en.wikipedia.org/wiki/Isolator_(microwave)

    An isolator is a non- reciprocal device, with a non- symmetric scattering matrix. An ideal isolator transmits all the power entering port 1 to port 2, while absorbing all the power entering port 2, so that to within a phase-factor its S-matrix is. To achieve non-reciprocity, an isolator must necessarily incorporate a non-reciprocal material.

  3. Lockout–tagout - Wikipedia

    en.wikipedia.org/wiki/Lockout–tagout

    The isolation procedure generally includes the following tasks: [2] Announce shut off; Identify the energy sources; Isolate the energy sources; Lock and tag the energy sources; Prove that the equipment isolation is effective; The locking and tagging of the isolation point lets others know not to de-isolate the device.

  4. 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 ...

  5. Mechanical energy - Wikipedia

    en.wikipedia.org/wiki/Mechanical_energy

    General. Energy is a scalar quantity and the mechanical energy of a system is the sum of the potential energy (which is measured by the position of the parts of the system) and the kinetic energy (which is also called the energy of motion): [1] [2] The potential energy, U, depends on the position of an object subjected to gravity or some other ...

  6. Isolation transformer - Wikipedia

    en.wikipedia.org/wiki/Isolation_transformer

    An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons or to reduce transients and harmonics. [1] Isolation transformers provide galvanic isolation; no conductive ...

  7. Heating element - Wikipedia

    en.wikipedia.org/wiki/Heating_element

    Heating element. A heating element is a device used for conversion of electric energy into heat, consisting of a heating resistor and accessories. [1] Heat is generated by the passage of electric current through a resistor through a process known as Joule Heating. Heating elements are used in household appliances, industrial equipment, and ...

  8. Solar cooker - Wikipedia

    en.wikipedia.org/wiki/Solar_cooker

    Parabolic Solar Cooker. A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize drink and other food materials. Many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves, and advanced, large scale solar cookers can cook for hundreds of people.

  9. Negative room pressure - Wikipedia

    en.wikipedia.org/wiki/Negative_room_pressure

    Negative room pressure is an isolation technique used in hospitals and medical centers to prevent cross-contamination from room to room. [1] [2] It includes a ventilation that generates negative pressure (pressure lower than that of the surroundings) to allow air to flow into the isolation room but not escape from the room, as air will ...
