156B Week 7

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Printed the first revision of our ergonomic grip and tested it. Made some modifications and printed revision 2.

  • Completed a full calibration of the 0.1-100N range (see below)

Accomplishments from Previous Week

• • Printed the ergonomic grip and a second one

  • Purchased and received 1 kg, 2 kg, and two 5 kg weights to calibrate the full 0.1-100N range (10g-10kg)

  • Set-up coax cable and did a calibration to compare it to the twisted pair - they performed the same outside an MRI, as expected.

  • Checked out the data acquisition system and got the LabView code -- need to install some drivers before we can work with it

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Test new second revision of ergonomic grip and decide if we need to print on nicer printer (Team)

  • Test in the MRI (Team)
