A portable electronic apparatus includes a main body, a camera device, and a supplementary light device. A disposable blood separation fluid circuit is provided which is adapted to cooperate with a reusable separation controller. The driveshaft supporting structure includes a bearing part that is mounted on a peripheral surface of the driveshaft at a location within the inner section of the hull. With early download sequence positioning of configuration data, and corresponding immediacy in initiation of operation, certain clock elements are able to commence initiation of operation while remaining clock elements are provided with configuration data from a latter portion of the download sequence. In addition, on detecting an overcurrent condition, the gate driver is disabled, which in turn switches off the MOSFETs.
