Abstract:

An apparatus includes an ultrasonic sensor array and a sensor controller. The sensor array includes a plurality of ultrasonic sensor pixels, each sensor pixel including an ultrasonic receiver and a receiver bias electrode and being operable in one or both of a transmit mode of operation or a read mode of operation. The sensor controller is electrically coupled with the receiver bias electrodes. The sensor controller is configured to set, at each sensor pixel, a range gate window (RGW) by modulating a bias voltage applied to the receiver bias electrode and to set, for a first portion of the ultrasonic sensor pixels, a first RGW. The sensor controller is configured to set, for a second portion of the ultrasonic sensor pixels, a second RGW, and establish a first temporal delay between the first RGW and the second RGW.

International Classification:

G06F 3/043
G06F 3/041

Abstract:

An apparatus includes an ultrasonic transmitter, an ultrasonic receiver, and an acoustic delay gradient layer disposed in an acoustic path between the ultrasonic transmitter and the ultrasonic receiver. The acoustic delay gradient layer is configured to cause a reflection from a platen interface of the transmitted ultrasonic signal to reach the first receiver region at a first time and the reflection from the platen interface of the transmitted ultrasonic signal to reach the second receiver region at a second time that is different from the first time. The apparatus can further include a controller configured to set for a first region or portion of the receiver, a first range gate window (RGW). The controller is also configured to set, for a second region or portion of the receiver, a second RGW, and to establish a first temporal delay between the first RGW and the second RGW.
