Goals for Fall  Design goals  Timeline: Fall 2008

Design Goals 4  Switching Scheme for Controlling Sensors Disconnect input from batteries Disconnect output from DAQ  LabVIEW Programming Data Management  GPS Interface Location stamping GPIB Interface  Temperature data  Testing/Calculations Latency and Power Consumption Cost per channel and BW for multiple chassis configuration

Timeline: Fall

Accomplishments to date 6  Redesigned Voltage Sensors  LabVIEW Programming  DFMEA

Sensors 7  Redesigned Voltage Sensors  Less power consumption  Only one voltage reference  Simplified design  Linear input to output
