An insertion instrument for a pair of sliding prostheses has, on a support plate, two clamps which are arranged at a predetermined spacing from one another and receive the sliding prostheses. A two-stage classification model can be trained and employed, where the first stage classification is optimized over the entire classification region and the second stage classifier is optimized for the specific region of interest. In certain example embodiments, short-circuited adjacent data lines are in communication with pixels of the same color. In addition, the host controller performs a host-side test preparation action. The present, invention relates to a metal gasket material plate comprising a metal plate 1 having a rubber layer 4 on one side or both sides thereof through an adhesive layer 3, wherein a rust-resistant pigment is added to both of said adhesive layer 3 and said rubber layer 4. Biometric identification is accomplished by extracting binary biometric data from video signals of characteristics images of a subject of biometric identification such as a finger at sequentially different image pickup positions in response to a relative movement of an image pickup element and the subject of biometric identification at a predetermined biological site.
