The invention provides a chip-and-PIN reader device having a slot for accommodating a chip-and-PIN card, a set of electrodes adapted to come into contact with corresponding electrodes on the card when the card is inserted into the slot, and a means for ensuring correct registration between the electrodes on the card and the set of electrodes of the reader device. Short opposing lengths of strip brushes are placing on either side of each of the slot openings in the cap. The device also receives, from the remote GPU, one or more results associated with execution of the transformed program command by the remote GPU, and utilizes the one or more results via the TCE. The register file includes a set of temporary data registers that are utilized by the instruction execution control unit to receive data results generated by the functional units. The water equivalent determined from the setting values for the irradiation is used as the value for the thickness of the body part to be examined. At least one of the first tooth and second tooth, is configured to extend at an angle upstream.
