  * Fabian did inventory of parts/fasteners for dummy BS, RM, IM and IRM - almost all at Mitaka. A handful (picos, pico drivers) will be brought back from Kamioka.
  * Fabian continued work on Mathematica and Matlab models of the BS and control system. He now gets much better agreement after correcting discrepancies between the parameter sets.
  * Hirata-san worked on organizing:
   * Checking Mirapro assembly frame drawings
   * Ordering missing screws and small items (screws for dummy mass, fine pitch M8 for RM)
   * Work platforms and clean booth second floor arrangement.
   * Load gauge adapter and associated parts
   * Possible fall-back plans for the rods connecting the security structure to the PI.
   * Design for additional trim masses (existing design had no provision for adding/removing).		   * Mark and Hirata-san at Mitaka
   * Gathered parts for cable making.
  * Mark and Hirata-san at Kamioka:
   * Replaced the floor panels that had been taken from the PR2 area (filling in the hole in the floor) and found/installed two new panels to act as bridges near the BS assembly frame.
   * Installed two more LPCDs and the stepper motor driver in the PR2 rack.
   * Ran cables from the rack to the second and third sat amps (for the IRM OSEMs).
   * Added a second DIO card in the rack and connected it to the BIO inputs and outputs of the new LPCDs.
   * Started making extension cables for RM-H2 and -H3 OSEMs but gave up due to complicated grounding arrangement.
   * Washed four 40-cm D-Sub-9 ribbon cables to use as temporary extensions (maybe also for H1/H4).
   * Added extension to the IM pico cable for the BF yaw pico.
   * Made LVDT adapter cable.
  * Mark worked on schedule.
