 * Type B Past Week Summary
  * Mark updated the BS circuit diagram [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=3600|D1503600]]:
   * Added information on the binary IO.
   * Renamed channels to conform to Okutomi-kun's new scheme.
   * Made the ADC/DAC channel assignment consistent and more logical.
   * Updated the stepper motor sections with info about the new driver chassis.
  * Mark and Hirata-san worked on collecting parts and tools that will be needed for cabling of the BS next week. (11 special-purpose cables need to be made for the picos/steppers/OSEMs/LVDT on the RM/IRM/IM/BF and, time permitting, 2 more for the SF.)
  * Mark worked on schedule.
  * Mark updated the installation procedure with lessons learned from the last few weeks.
  * Mark downloaded Hirata-san's Inventor model of the BS in the tank and starting thinking about installation of the suspension and lower bread board.		 === Type B (Mark) ===
==== Past week report ====

 * Mark and Fabian did a huge cleanup of the SR2 area and prepared a workspace for assembling the IM.
 * Fabian did a stocktake of the screws for the SR.
  * We have all we need for the IM, except one type that can be added after the rest of the IP is assembled.
  * We have most of what we need for the rest of the payload, and Hirata-san has ordered the others.
 * Hirata-san worked on SR procurement:
  * Suspension wire
  * SR additional parts (compensation masses, clamps etc)
  * Regular, SDC and BUMAX screws.
  * Additional machining on the BS sapphire prism jig to allow it to be used on the PR/SR mirror box.
  * LBB blade design.
 * Enzo and Kozu-kun (with help from Fujii-kun) worked on export from SUMCON to Matlab, and on filter design).
