A stapler unit has a staple section, a cutter section, and a receiving section. The captured screenshot data may, for example, be used to recover a device that is lost or stolen. The number of relatively dark pixels is then counted, pixel number thresholds are determined to quantify scoring, and the number of relatively dark pixels is compared with the thresholds to provide a second contribution scoring of ER or PR. When the two panels are aligned so that clear areas are adjacent, there is viewing through the window. The operation determination module is configured to determine that an operator is operating the vehicle based on a subset of the data. Operating logic uses data paths of the processor core to implement the ABIST.
