  2. Friending and following - Wikipedia

    en.wikipedia.org/wiki/Friending_and_following

    Following is a similar concept on other social network services, such as Twitter and Instagram, where a person (follower) chooses to add content from a person or page to their newsfeed. Unlike friending, following is not necessarily mutual, and a person can unfollow (stop following) or block another user at any time without affecting that user ...

  3. Buffer amplifier - Wikipedia

    en.wikipedia.org/wiki/Buffer_amplifier

    For a current buffer, if the current is transferred unchanged (the current gain β i is 1), the amplifier is again a unity gain buffer; this time known as a current follower because the output current follows or tracks the input current. As an example, consider a Norton source (current I A, parallel resistance R A) driving a resistor load R L.

  4. Dwell mechanism - Wikipedia

    en.wikipedia.org/wiki/Dwell_mechanism

    Cam-follower dwell mechanisms are used in pairs in sewing machines to operate the four motion feed dogs, with one cam moving the dog up and down, and the other cam moving the dog forwards and backwards. The cams in this application are usually phased 90 degrees apart allowing a pause in the up/down movement of the dog while it is being moved ...

  5. Cam follower - Wikipedia

    en.wikipedia.org/wiki/Cam_follower

    A cam follower, also known as a track follower, [1] is a specialized type of roller or needle bearing designed to follow cam lobe profiles. Cam followers come in a vast array of different configurations, however the most defining characteristic is how the cam follower mounts to its mating part; stud style cam followers use a stud while the yoke style has a hole through the middle.

    en.wikipedia.org/wiki/Common_drain

    In electronics, a common-drain amplifier, also known as a source follower, is one of three basic single-stage field-effect transistor (FET) amplifier topologies, typically used as a voltage buffer. In this circuit (NMOS) the gate terminal of the transistor serves as the signal input, the source is the output, and the drain is common to both ...

  9. Lead and follow - Wikipedia

    en.wikipedia.org/wiki/Lead_and_follow

    Traditionally, the male dance partner is the leader and the female dance partner is the follower, though this is not always the case, such as in Schottische danced in the Madrid style where women lead and men follow (although this is not totally true: during the dance there is an exchange of roles, the leader becomes the follower and vice versa [3]).
