  2. Time-to-digital converter - Wikipedia

    en.wikipedia.org/wiki/Time-to-digital_converter

    The first direct predecessor of a TDC was invented in the year 1942 by Bruno Rossi for the measurement of muon lifetimes. [21] It was designed as a time-to-amplitude-converter, constantly charging a capacitor during the measured time interval. The corresponding voltage is directly proportional to the time interval under examination.

    en.wikipedia.org/wiki/Time-of-flight_mass...

    The TDC is a counting detector – it can be extremely fast (down to a few picosecond resolution), but its dynamic range is limited due to its inability to properly count the events when more than one ion simultaneously (i.e., within the TDC dead time) hit the detector. The outcome of limited dynamic range is that the number of ions (events ...

    en.wikipedia.org/wiki/Torpedo_Data_Computer

    The Torpedo Data Computer (TDC) was an early electromechanical analog computer used for torpedo fire-control on American submarines during World War II. Britain , Germany , and Japan also developed automated torpedo fire control equipment, but none were as advanced as the US Navy 's TDC, [ 1 ] as it was able to automatically track the target ...

  7. Transcranial direct-current stimulation - Wikipedia

    en.wikipedia.org/wiki/Transcranial_direct...

    Transcranial direct current stimulation (tDCS) is a form of neuromodulation that uses constant, low direct current delivered via electrodes on the head. This type of neurotherapy was originally developed to help patients with brain injuries or neuropsychiatric conditions such as major depressive disorder.

  8. Leading question - Wikipedia

    en.wikipedia.org/wiki/Leading_question

    A leading question is a question that suggests a particular answer and contains information the examiner is looking to have confirmed. [1] The use of leading questions in court to elicit testimony is restricted in order to reduce the ability of the examiner to direct or influence the evidence presented. Depending on the circumstances, leading ...

    The former is known as top dead centre (TDC) while the latter is known as bottom dead centre (BDC). [1] Position of pistons. More generally, the dead centre is any position of a crank where the applied force is straight along its axis, meaning no turning force can be applied.
