Abstract

Official abstract text for this publication.

A device includes both a fingerprint sensor ( 112 ) and a piezo structure ( 114 ). The fingerprint sensor senses fingerprint data identifying a pattern of a fingerprint of a user. The fingerprint data for the user can be collected and analyzed in various manners in order to authenticate the sensed fingerprint. The piezo structure can be used in various manners, such as to collect data used to facilitate authenticating the sensed fingerprint data, to provide feedback to the user regarding when the fingerprint authentication process is complete, and/or to cause different types of vibration in order to facilitate sensing fingerprint data. Various additional feedback can also be provided to the user, using the piezo structure or other feedback mechanisms, such as feedback to notify the user to increase or decrease an amount of pressure he or she is applying to the fingerprint sensor.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method comprising: starting vibrating a sensor structure, in response to at least a first threshold pressure being applied to the sensor structure of a device by a finger; analyzing fingerprint data sensed by the sensor structure, to authenticate a fingerprint of the finger; varying vibration of the sensor structure while analyzing the fingerprint data; and ceasing vibrating the sensor structure, in response to completing analyzing of the finge…
