    Abstract: An ultrasonic biometric scanner includes an ultrasonic multiple scan element array with multiple scan elements. The array includes piezoelectric material such as lead zirconate titanate or polyvinylidene difluoride with a first electrode on a first surface and a second electrode on a second, opposite surface. At least one of the first electrode or the second electrode include multiple electrodes wherein the number of the multiple electrodes corresponds to a number of the multiple scan elements. A substrate is electrically coupled to the second electrode and/or the first electrode. A cover may be positioned over the first electrode. The cover has an acoustic impedance matching ultrasonic signals emitted by the piezoelectric material.

    Abstract: An acoustic imaging system includes multiple transducers disposed to circumscribe a portion of substrate. An acoustic imaging system also includes a controller and an image resolver. The transducers convert electrical signals into mechanical energy and/or mechanical energy into electrical signals. The controller is adapted to apply an electrical signal to the transducers which, in response, induce a mechanical wave, such as a surface wave, into the circumscribed portion. The controller is also adapted to receive electrical signals from the transducers. The image resolver uses the electrical signals received by the controller in order to construct an image of an object in physical contact with the substrate.

    Abstract: A finger biometric sensing device may include an array of finger biometric sensing pixel electrodes and a gain stage coupled to the array of finger biometric sensing pixel electrodes. The finger biometric sensing device may also include error compensation circuitry that may include a memory capable of storing error compensation data. The error correction circuitry may also include a digital-to-analog converter (DAC) cooperating with the memory and coupled to the gain stage and capable of compensating for at least one error based upon the stored error compensation data.

    Abstract: A processing channel is operatively connected to a biometric device. The processing channel includes an analog-to-digital converter (ADC) connected to at least one of an amplifier and an offset circuit. Biometric signals representing captured biometric data, such as a fingerprint image, are controllably fitted into an input range of the ADC. The ADC input range can include one or more removed ranges and one or more adjustable allowed input ranges. One or more channel parameters are adjusted until a desired number of biometric signals are included in the one or more removed ranges.

    Abstract: A biometric sensor device, such as a fingerprint sensor, comprises a substrate to which is mounted a die on which is formed a sensor array and at least one conductive bezel. The die and the bezel are encased in a unitary encapsulation structure to protect those elements from mechanical, electrical, and environmental damage, yet with a portion of the sensor array and the bezel exposed or at most thinly covered by the encapsulation or other coating material structure.
