  • Publication number: 20140016838
    Abstract: An apparatus for reducing noise in fingerprint sensing circuits is disclosed in one embodiment of the invention as including a fingerprint sensing area onto which a user can apply a fingerprint. An analog front end is coupled to the fingerprint sensing area and is configured to generate an analog response signal. An analog-to-digital converter (ADC) samples the analog response signal and converts the sample to a digital value, which may be received by a digital device such as a processor or CPU. To reduce the amount of the noise that is present in the analog response signal and therefore reflected in the digital value, the digital device may be shut down while the ADC is sampling the analog response signal.

  • Patent number: 8600122
    Abstract: An apparatus for culling substantially redundant data in a fingerprint sensing circuit is disclosed in one embodiment of the invention as including an input module, a storage module, a comparator module, and a determination module. The input module may receive sets of data samples from an array of fingerprint sensing elements. The sets of data samples may be stored by the storage module. The comparator module may calculate a difference between each data sample from a first-received set, and a corresponding data sample from a second-received set. The determination module may count the number of difference values that exceed a predetermined difference limit, and identify the second set of data samples as redundant if the number of difference values counted is less than a pre-set count limit.

    Abstract: A system and method is disclosed for comparing biometric image data to a stored enrollment template that may comprise collecting a set of biometric image data for a biometric object image from a biometric object imaging sensor; storing the biometric object image data in a memory as an enrollment template for further comparison to find a match with subsequently imaged biometric object image data; collecting a subsequent set of biometric image data for a biometric object image from the biometric object imaging sensor; updating the enrollment template; determining if a limited enrollment window remains open; and repeating the collecting of a subsequent set of biometric data step if the enrollment window remains open. Determining if the enrollment window remains open may be by determining the existence of one of a stability indicator and an instability indicator.

  • Patent number: 8391568
    Abstract: A fingerprint analysis method for partial fingerprint scanners that has an improved ability to resolve fingerprints from the tips of fingers, as well as an improved ability to cope with suboptimal finger swipes. The method uses various extrapolation methods to more accurately determine the position of a scanned fingertip is as the tip of the finger passes a partial fingerprint scanner. The method also monitors the image characteristics of the partial fingerprint image returned by the partial fingerprint scanner, and uses these image characteristics to determine exactly where the image of the fingertip itself is lost, and imaging of non-fingerprint data begins. By combining the most probable fingertip position as a function of time data obtained from extrapolated finger motion data, with image analyzed fingerprint images more precisely determined to be near the fingertip edges, superior fingerprint images extending closer to the edge of the fingerprint may be obtained.

The injected radio frequency energy causes the object to radiate an electric field. A pickup plate is configured to detect an intensity associated with the electric field radiated by the object. A sensor coupled to the pickup plate is configured to determine whether the object is a live finger based on the detected intensity of the electric field radiated by the object.

  • Patent number: 8358815
    Abstract: Enhanced accuracy finger position and motion sensors devices, algorithms, and methods are disclosed that can be used in a variety of different applications. The sensors can be used in conjunction with partial fingerprint imagers to produce improved fingerprint scanners. The finger motion sensors may also be used (either with or without a partial fingerprint imager) to control electronic devices. When several of these finger motion and position sensors are aligned in different directions, finger motion over a two dimensional surface may be detected. This creates a finger controlled “mouse” computer input device. Motion of a finger along the surface of such sensors may allow a user to control the movement of an indicator on a display screen, and control a microprocessor device. Such techniques are particularly useful for small space constrained devices, such as cell phones, smart cards, music players, portable computers, personal digital accessories, and the like.

  • Patent number: RE44440
    Abstract: A system and method is disclosed for minimizing power consumption of a sensor unit that is capable of detecting an object. Main circuitry operates the sensor unit in a high power mode of operation when the sensor unit detects an object. Low power control circuitry operates the sensor unit in a low power mode of operation when the sensor unit does not detect an object within a pre-determined period of time. The low power control circuitry also comprises a counter to periodically determine when to restore the sensor unit to a high power mode of operation. One advantageous embodiment of the sensor unit is a fingerprint sensor unit for detecting a finger to obtain fingerprint information.
