2. THE ANALOG THING - Wikipedia

   en.wikipedia.org/wiki/THE_ANALOG_THING

   The computer is programmed with patch cables connecting the components on a switching board. It can, additionally, be partly controlled from a digital computer via a hybrid port. If an application requires more computing elements than are available on a single machine, two or more THATs can be coupled via dedicated interfaces referred to as ...

3. Switched-mode power supply - Wikipedia

   en.wikipedia.org/wiki/Switched-mode_power_supply

   Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.

   A. Nakagawa et al. invented the device design concept of non-latch-up IGBTs in 1984. [19] [20] The invention is characterized by the device design setting the device saturation current below the latch-up current, which triggers the parasitic thyristor. This invention realized complete suppression of the parasitic thyristor action, for the first ...

   Very small (1.6×1.6×0.35 mm) red, green, and blue surface mount miniature LED package with gold wire bonding details. These are mostly single-die LEDs used as indicators, and they come in various sizes from 1.8 mm to 10 mm, through-hole and surface mount packages. [47] Typical current ratings range from around 1 mA to above 20 mA.
