- * 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.
