The First Officer lifted his backpack which was on the floor behind his seat. His bag strap caught onto the DC Standby Bus CB and there was a momentery power interuption in the DC standby bus. The subsequent result in the power interuption was the loss of the L ENG EEC normal mode. Per checklist and conference with Maintenance; both engines were placed in the EEC ALT MODE resulting in the loss of the autothrottles. Flight continued and landed with no further problems.
