Assignee: QUALCOMM INCORPORATED
Field: Computer technology (Electrical engineering)
Classification: CPC G  Y | IPC G

Claim 19:
20. The non-transitory computer readable medium of claim 19, wherein the subset of the array of ultrasonic transducers is a first subset of the array of ultrasonic transducers;
wherein the non-transitory computer readable medium further comprises instructions that, when executed by the hardware processor, causes the hardware processor to: disable a second subset of the array of ultrasonic transducers, or reduce a power level of the second subset of the array of ultrasonic transducers, when the first subset of the array of ultrasonic transducers perform the ultrasonic sensing operation;
wherein the object comprises a finger; and
wherein the action comprises:
generating an image of the finger based on a distribution of signal strengths of reflected ultrasonic signals; and
transmitting the image to another component to enable the another component to compare the image with a reference image of a fingerprint to generate a comparison result, and to control access to a function of a device based on the comparison result.
