2. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A smart charger can respond to the condition of a battery and modify its charging parameters accordingly, whereas "dumb" chargers apply a steady voltage, possibly through a fixed resistance. It should not be confused with a smart battery that contains a computer chip and communicates digitally with a smart charger about battery condition. A ...

3. 4D printing - Wikipedia

   en.wikipedia.org/wiki/4D_printing

   Stereolithography is a 3D-printing technique that uses photopolymerization to bind substrate that has been laid layer upon layer, creating a polymeric network. As opposed to fused-deposition modeling, where the extruded material hardens immediately to form layers, 4D printing is fundamentally based in stereolithography, where in most cases ultraviolet light is used to cure the layered ...

4. Smart battery - Wikipedia

   en.wikipedia.org/wiki/Smart_battery

   A smart battery or a smart battery pack is a rechargeable battery pack with a built-in battery management system (BMS), usually designed for use in a portable computer such as a laptop. [ 1 ] [ 2 ] In addition to the usual positive and negative terminals, a smart battery has two or more terminals to connect to the BMS; typically the negative ...

5. Smart charging - Wikipedia

   en.wikipedia.org/wiki/Smart_charging

   Smart charging transfers a portion of the peak load to off-peak hours. The predictability of energy demand is also improved because of the capability to use V2G as a backup. Study shows that a smoother and more predictable energy demand curve will boost the proportion of green energy in total energy production.

6. 4D scanning transmission electron microscopy - Wikipedia

   en.wikipedia.org/wiki/4D_scanning_transmission...

   The name 4D STEM is common in literature, however it is known by other names: 4D STEM EELS, ND STEM (N- since the number of dimensions could be higher than 4), position resolved diffraction (PRD), spatial resolved diffractometry, momentum-resolved STEM, "nanobeam precision electron diffraction", scanning electron nano diffraction (SEND ...

7. Trickle charging - Wikipedia

   en.wikipedia.org/wiki/Trickle_charging

   Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, enabling the battery to remain at its fully charged level. This state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.

   "The potential dangers of using at-home LED masks include headaches, eye strain, sleep disturbances, insomnia and mild visual side effects," she explained.

9. Solar charger - Wikipedia

   en.wikipedia.org/wiki/Solar_charger

   A solar charger is a charger that employs solar energy to supply electricity to devices or batteries. They are generally portable. Solar chargers can charge lead acid or Ni-Cd battery banks up to 48 V and hundreds of ampere hours (up to 4000 Ah) capacity. Such type of solar charger setups generally use an intelligent charge controller.
