Jonathan Holdsworth

Tasks / Description of Activities / Date Completed / Other team members involved with task
DAQ System / Began in depth review of DAQ system involved with the Thermoelectric Module, including reviewing Nat. Instruments datasheets. (“Can the current board accept low voltage readings?”) / TBD
Shunt Resistor Verifications for various loads. / Ran additional simulations for impact of shunt resistor (Conclusion: IS acceptable at all necessary load resistances) / 1/23/09
MOSFET for impedance matching / Looked into the possibility of using a MOSFET for matching impedances to get peak power. (Conclusion: Power MOSFET) / 1/23/09 / Ken McLoud
Changing load resistance in electrical schematic / Changed load resistance to include both the variable resistance AND the shunt resistance, instead of just the variable resistance. / 1/22/09

Tasks / Description of Activities / Date Completed / Other team members involved with task
Experiment on test stand. / Experiment to determine the effect of the groove (if any) on module performance. Gather any relevant information lending itself to the inference of the groove’s impact (if any) on local module surface temperature. / 1/19/09 / no

Andy Freedman

Tasks / Description of Activities / Date Completed / Other team members involved with task
Groove Heat Flux Modeling / Revisited refined model of the FEA of the groove determining that there is only a degree or so difference. This matched experimental testing done by John. Dr. Stevens is willing to accept this difference but wants grooves made to be smaller with smaller thermocouples permanently fixed. / 1/23 / Individual
Disassembled Power Unit / Disassembled the power unit and made some measurements. Further evaluated grooves and assembly process. / 1/19 / Individual
Cool Air Piping & Fittings Search / Started to look at some options available for piping and fittings for cool air flow and potential issues. / 1/17 / Individual
Drawing Piping Layout / Assisted in drawing parts for the piping layout assembly. / 1/23 / Ken
