1. A system comprising:
- an electronic device operable to perform functional operations when power is activated in the electronic device; and
a sensor assembly comprising;
a mounting module; and
a fingerprint sensor incorporated into the mounting module and electrically connected to the electronic device, wherein the fingerprint sensor includes a sensing area that is exposed by the mounting module,wherein the sensor assembly includes at least two different security levels for signals from the fingerprint sensor, wherein each security level is associated with at least one functional operation of the electronic device, and wherein access to a functional operation of the electronic device requires authentication of a signal from the fingerprint sensor at the associated security level.

Abstract
A novel sensor is provided having a plurality of substantially parallel drive lines configured to transmit a signal into a surface of a proximally located object and also a plurality of substantially parallel pickup lines oriented proximate the drive lines and electrically separated from the drive lines to form intrinsic electrode pairs that are impedance sensitive at each of the drive and pickup proximal locations. A switch is integrated with the sensor.

16. A method for accessing functional operations in an electronic device having a fingerprint sensor for user authorization, wherein the electronic device is operable to perform the functional operations when power is activated in the electronic device, the method comprising:
-
with a fingerprint sensor, obtaining a fingerprint image at a first resolution for performing a user authentication at a first security level, wherein access to a first functional operation of the electronic device requires authentication of a signal from the fingerprint sensor at the first security level; and with the fingerprint sensor, obtaining a fingerprint image at a second resolution different from the first resolution for performing a user authentication at a second security level different from the first security level, wherein access to a second functional operation of the electronic device different from the first functional operation of the electronic device requires authentication of a signal from the fingerprint sensor at the second security level. - View Dependent Claims (17, 18, 19, 20)
