  2. Diathermy - Wikipedia

    en.wikipedia.org/wiki/Diathermy

    Diathermy is electrically induced heat or the use of high-frequency electromagnetic currents as a form of physical therapy and in surgical procedures. The earliest observations on the reactions of the human organism to high-frequency electromagnetic currents were made by Jacques Arsene d'Arsonval .

    en.wikipedia.org/wiki/ISM_radio_band

    "The delegate of the United States, referring to his request that the frequency 2450 Mc/s be allocated for I.S.M., indicated that there was in existence in the United States, and working on this frequency a diathermy machine and an electronic cooker, and that the latter might eventually be installed in transatlantic ships and airplanes.

  4. Block diagram - Wikipedia

    en.wikipedia.org/wiki/Block_diagram

    A block diagram is a diagram of a system in which the principal parts or functions are represented by blocks connected by lines that show the relationships of the blocks. [1] They are heavily used in engineering in hardware design , electronic design , software design , and process flow diagrams .

  5. Process flow diagram - Wikipedia

    en.wikipedia.org/wiki/Process_flow_diagram

    A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

  6. Radio frequency - Wikipedia

    en.wikipedia.org/wiki/Radio_frequency

    Medical applications of radio frequency (RF) energy, in the form of electromagnetic waves (radio waves) or electrical currents, have existed for over 125 years, [9] and now include diathermy, hyperthermy treatment of cancer, electrosurgery scalpels used to cut and cauterize in operations, and radiofrequency ablation.

    en.wikipedia.org/wiki/File:Reflex_receiver_block...

    English: Block diagram of a simple reflex radio receiver, an unusual type of radio receiver invented by Marius Latour and William Preiss in 1917 that was used to a limited extent in the 1920s. The distinguishing feature of the reflex circuit is that the amplifier is used to amplify both the radio frequency (RF) and audio frequency (AF) signals ...
