Smart accumulator tester and charger
Mílek, Čestmír ; Trmač, Jiří (referee) ; Michálek, Václav (advisor)
Nickel cadmium and nickel metal hydride accumulators sets are currently used for supplying hand tools (screwdrivers,...). Problems of cheap hand tools are chargers, mostly of it doesn’t use any charging driving circuits. In consequence of it the accumulators are kept incorrectly, which causes lowernig of lifetime. This thesis suggest circuit design Main of intelligent charging system, which enable better battery management, increases battery lifetime and lower load of environment.

Contactless measuring ventilator-revolution counter
Pokorný, Aleš ; Trmač, Jiří (referee) ; Michálek, Václav (advisor)
This project is about design of contactless measuring ventilator - revolution counter. The counter serves to measurement of the speed of ventilator. The measurement is based on optical method of receiving the reflected laser beam. To measure and calculate use the revolution counter the microcontroller. This measured value is diplayed on LCD. After design follows experimental measurement.
