A spread illuminating apparatus includes a light conductive plate provided with a light entry face at its corner, having a spot-like light source disposed close to or in contact with the light entry face, and having a light reflection pattern formed on its major surface. The processing system includes an interconnect fabric that includes hot plug connector at which an external hot-pluggable component can be coupled to the data processing system and logic components include configuration logic and routing and operating logic. The transmission provides at least nine forward speed ratios and a reverse speed ratio and utilizes only eight torque-transmitting mechanisms. The locking portion is on the other side of the battery and is opposite to the connecting portion. Once calibrated, the test stations may be used during product testing to test factory DUTs to determine whether a particular production DUT satisfies passfail criteria.
