Abstract: A two-wire interface (300) for connecting a first device (106) and a second device (108). The two-wire interface (300) is operable in a handshaking mode and a data transfer mode. In the handshaking mode the first wire (302) of the interface (300) is driven by the first device (106) and the second wire (304) of the interface (300) is driven by the second device (108) so that the first (106) and second (108) devices can perform a handshaking sequence. In the data transfer mode one of the first wire (302) and the second wire (304) is driven by one of the first (106) and second (108) devices to provide a clock signal, and the other wire is driven by either the first device (106) or the second device (108) depending which device is transmitting data. Accordingly, the two-wire interfaces (300) are operable in two modes (e.g. handshaking mode and data transfer mode) and one of the wires (302, 304) of the interface (300) may be driven by a different device in the two modes.

Abstract: A system, method, and computer program product for efficiently mapping a pattern, such as a fingerprint, from a set of multiple impressions of portions of that pattern. The system may evaluate images of patterns taken from a series of multiple impressions and map the pattern from the image portions while providing the operator with realtime feedback of a status of the set of images. As each new image portion is evaluated, a display graphic or other indicator provides feedback when a new image portion is added to the reconstructed image, or when a new image portion is not added (such as it representing a duplicate). Other status indications may be provided, and when the indication is visual, a degraded resolution of the pattern map may be provided on the display graphic to improve security.
