Abstract: A fingerprint sensing module includes a sensor substrate having a sensing side and a circuit side, an image sensor including conductive traces on the circuit side of the sensor substrate, and a sensor circuit including at least one integrated circuit mounted on the circuit side of the sensor substrate and electrically connected to the image sensor. The sensor substrate may be a flexible substrate. The module may include a velocity sensor on the sensor substrate or on a separate substrate. The module may further include a rigid substrate, and the sensor substrate may be affixed to the rigid substrate.

Abstract: A fingerprint sensor which includes a conductive layer which is incorporatable within an electronic display is disclosed. The fingerprint sensor also includes a controller coupled to the conductive layer to capture a fingerprint image and can further be adapted to control the display.

Abstract: A fingerprint scanning and image reconstruction system and method including a fingerprint scanner providing a first scan line and a second scan line separated by a line separation distance in a scanning direction. The system includes an image reconstruction module accumulating scan lines including at least the first scan line and the second scan line over a time period t. The image reconstruction module a value for decimation (t) necessary to produce a selected y axis resolution in the scanning direction based at least in part on (line count(t)/line separation distance)*a selected y resolution, where line count(t) is the number of lines accumulated in time t, and decimation(t) indicates of whether the line count(t) is greater than or less than the number of lines accumulated as a function of the time period t that will result in a selected reconstructed image y resolution in the scanning direction.

Abstract: A user input method and apparatus may comprise a two line object imaging sensor having a primary line scan-sensor providing a primary line scan-sensor output and a secondary line scan-sensor providing a secondary line scan-sensor output, representing pixels in a current primary scan row and a current secondary scan row, and adapted to scan an object; storing for each scan time each current primary line scan-sensor output and each current secondary line scan-sensor output and a correlation unit correlating at least one of the current representations of pixels in a primary line sensor output with stored representations and the current representations of pixels in a secondary line sensor output with stored representations and, the correlation unit providing as an output a motion indicator.
