    en.wikipedia.org/wiki/Smps

    SMPS may refer to: Scanning mobility particle sizer, an analytical instrument for aerosol particles; Switched-mode power supply, a type of electronic power supply;

  6. Power supply unit (computer) - Wikipedia

    en.wikipedia.org/wiki/Power_supply_unit_(computer)

    Now all modern computers use switched-mode power supplies, which are lighter, less costly, and more efficient than equivalent linear power supplies. Computer power supplies may have short circuit protection, overpower (overload) protection, over-voltage protection, under-voltage protection, over-current protection, and over-temperature protection.

  7. Scanning mobility particle sizer - Wikipedia

    en.wikipedia.org/wiki/Scanning_mobility_particle...

    The air now contains only particles of a certain diameter. The flow is introduced into a CPC, a condensation particle counter, which measures the concentration of particles in an aerosol sample. The CPC works by using butanol vapor condensation on the particles present in the air sample. The particles are exposed to butanol vapor heated to 39 °C.

  8. Shape-memory polymer - Wikipedia

    en.wikipedia.org/wiki/Shape-memory_polymer

    Shape-memory polymers (SMPs) are polymeric smart materials that have the ability to return from a deformed state (temporary shape) to their original (permanent) shape when induced by an external stimulus (trigger), such as temperature change.

  9. Uninterruptible power supply - Wikipedia

    en.wikipedia.org/wiki/Uninterruptible_power_supply

    A large data-center-scale UPS being installed by electricians. An uninterruptible power supply (UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails.
