  2. IUoU battery charging - Wikipedia

    en.wikipedia.org/wiki/IUoU_battery_charging

    IUoU is a DIN-designation [1] (DIN 41773) for a lead-acid battery charging procedure that is also known as 3-stage charging, 3-phase charging, or 3-step charging. It consists of three phases (or stages), to be executed by a battery charger .

  3. Star quad cable - Wikipedia

    en.wikipedia.org/wiki/Star_quad_cable

    The magnetic immunity of star quad cable is a function of the accuracy of the star-quad geometry, the accuracy of the impedance balancing, and the common-mode rejection ratio of the balanced receiver. [2] Star-quad cable typically provides a 10 dB to 30 dB reduction [3] in magnetically-induced interference. [4] [5] [6]

    en.wikipedia.org/wiki/Shark!_Shark!

    Shark! is an Intellivision game originally designed by Don Daglow, and with additional design and programming by Ji-Wen Tsao, one of the first female game programmers in the history of video games. The player is a fish who must eat smaller fishes in order to gain points and extra lives while avoiding enemies such as larger fishes, sharks ...

  5. Bridged and paralleled amplifiers - Wikipedia

    en.wikipedia.org/wiki/Bridged_and_paralleled...

    A bridge-parallel amplifier topology is a hierarchical combination of the bridged and paralleled amplifier topologies, with at least four single-ended channels needed to produce one bridge-parallel channel. The two topologies complement each other in that the bridging allows for higher voltage output and the paralleling provides the current ...

  6. Negative resistance - Wikipedia

    en.wikipedia.org/wiki/Negative_resistance

    [86] [138] [139] [140] A circulator is a nonreciprocal solid-state component with three ports (connectors) which transfers a signal applied to one port to the next in only one direction, port 1 to port 2, 2 to 3, and 3 to 1. In the reflection amplifier diagram the input signal is applied to port 1, a biased VCNR negative resistance diode N is ...

  7. Incremental encoder - Wikipedia

    en.wikipedia.org/wiki/Incremental_encoder

    Many incremental encoders have an additional output signal, typically designated index [2] or Z, [3] which indicates the encoder is located at a particular reference position. Also, some encoders provide a status output (typically designated alarm) [4] that indicates internal fault conditions such as a bearing failure or sensor malfunction.

    Females can grow to 22.5 m (6.6–8.2 ft), males up to 1.8 m (5.9 ft). The maximum recorded weight is 240 kg (530 lb). [ 3 ] Female sandbar sharks have an average fork-length (tip of the nose to fork in the tail) of 154.9 cm with the males' average fork-length being 151.6 cm. [ 4 ] Its body color can vary from a blue-ish brown, grey or ...

    en.wikipedia.org/wiki/Shark_anatomy

    Shark Anatomy (50693674756) The gill slits of a whale shark flaring as it expels water from its pharyngeal cavity. In the shark anatomy image, it depicts the beginning half of the shark, including the gills. The shark gills are especially important and were evolved from the chordate pharyngeal gill slits synapomorphy.
