    Additionally, there is a PIC 16F84 micro controller which receives the data from the FPGA, and sends … This chip uses a built in charge pump to bring the TTL logic levels (0-5 volts ) up to the RS232 voltage levels of - 12 to 12 volts. There is also a port called a 'ByteBlaster' programming port that is used to fill the contents …
  • CR4 - Thread: Active PC cooling
    There are a couple of reasons for this, firstly they run on 12 volts so, designing and building some sort of Uninterruptible Power Supply is much simpler, as it doesn't require the inverter to convert the 12 V DC battery power back … For interfacing the system with the real world the best way to go is a Programmable Logic Controller .
  • Self tuned PID based speed control of PMDC drive
    … system to control the Permanent Magnet DC (PMDC) Motor speed at desired speed (set point) through the technique of soft computing based self tuning of Proportional - Integral-Derivative controller which is designed in the platform of LabVIEW program , and the real - time … The application of soft computing (Fuzzy Logic ) to the PID controller imparts it the ability of tuning … Simulated results in LabVIEW using Fuzzy-PID toolkit and also the same has been implemented and tested for a 12 volt DC motor.
  • Electric and Hybrid Vehicle Program, Site Operator Program. Quarterly progress report for July through September 1994 (Fourth quarter of fiscal year 1994)
    A preventative maintenance program for the fleet, implemented in CY-90, checks each vehicle at 6 to … Failure of the 12 - volt auxiliary battery from heavy accessory drain causes the speed controller to lose logic .
