| 20160379035 | DOUBLE-SIDED FINGERPRINT SENSOR - A sensor has parallel upper pickup lines in an upper conductive layer, parallel lower pickup lines in a lower conductive layer, parallel drive lines oriented transversely to the upper and lower pickup lines in a middle conductive layer, a first insulating layer separating the upper pickup lines from the drive lines, and a second insulating layer opposite the first insulating layer and separating the lower pickup lines from the drive lines. Upper electrode pairs are defined at locations where an upper pickup electrode crosses a drive line, and each upper electrode pair has an impedance that is sensitive to a first object contacting or in close proximity to the upper electrode pair. Lower electrode pairs are defined at locations where a lower pickup line crosses a drive line, and each lower electrode pair has an impedance that is sensitive to a second object contacting or in close proximity to the lower electrode pair. | 12-29-2016 |
| 20160379037 | MULTI-RESOLUTION FINGERPRINT SENSOR - Multi-resolution fingerprint sensors and methods of using the same are provided. The multi-resolution fingerprint sensors each include a portion of the imaging area or region of the sensor that provides higher imaging resolution than the remaining imaging area of the sensor. The area of higher resolution is useful for anti-spoofing purposes, but because only a portion of the sensor is higher-resolution, advantageously it will not impact hardware costs nearly as much as a sensor that was higher resolution over its entire imaging area. Furthermore, the higher resolution area can be down-sampled so there would be no impact on the standard matcher and image processing software stack, which expects a uniform resolution for the entire image acquired. | 12-29-2016 |
| 20160379038 | VALID FINGER AREA AND QUALITY ESTIMATION FOR FINGERPRINT IMAGING - Techniques for fingerprint quality assessment are presented. In some embodiments, a fingerprint image is subdivided into a plurality of sub-images. An orientation and a frequency associated with fingerprint ridges or valleys can be determined for each sub-image. A model can be generated for each sub-image and then compared to each sub-image. Based on the comparing, a quality assessment can be determined for each of the sub-images. | 12-29-2016 |
