    Dynamic Braking Resistors (DBRs) - (26 companies)
    Dynamic braking resistors (DBRs) produce braking torque and absorb the high amounts of energy generated by stopping electric motors. They are used in variable-speed drive systems such as elevators, cranes, and trains. Some DBRs are also used...
  •  
    Current Sensing Resistors - (69 companies)
    Current sensing resistors convert the current flowing through it to a voltage drop. Monitoring or measuring this voltage drop allows the current through the resistor to be measured. Applications for current sensing resistors include power supplies...
  •  
    Circular Variable Filters - (6 companies)
    Circular variable filters provide linear attenuation of incident light by rotating the filter. Circular variable filters are doughnut-shaped devices that allow narrow wavelengths from the electromagnetic spectrum to pass through circular substrates...

    It also eliminates the traditional optocoupler ’s CTR varia- tions with power supply and voltage, and the need to suffer the additional voltage drop of a series resistor .
  • Memristor Networks
    The float- ing memristor can be emulated most conveniently via a floating two-terminal de- vice with variable resistance, for example the digital potentiometer [6] or the light- dependent resistor (LDR) as a part of the optocoupler [3, 4].
