Abstract: A method may involve receiving fingerprint sensor data from a fingerprint sensor system, detecting, according to the fingerprint sensor data, a presence of a digit on an outer surface of the apparatus in a fingerprint sensor system area; determining, according to the fingerprint sensor data, a digit force or a digit pressure of the digit on the outer surface of the apparatus; and making, according to the fingerprint sensor data, a time threshold determination. The time threshold determination may involve determining whether a length of time during which the digit force exceeds a threshold digit force or during which the digit pressure exceeds a threshold digit pressure is greater than or equal to a threshold length of time. The method may involve determining, based at least in part on the time threshold determination, whether to enable one or more emergency response functions of the apparatus.

Abstract: Some disclosed implementations include an ultrasonic sensor stack and an acoustic resonator. The acoustic resonator may be configured to enhance ultrasonic waves transmitted by the ultrasonic sensor stack in an ultrasonic frequency range that is suitable for ultrasonic fingerprint sensors. In some examples, the acoustic resonator may include one or more low-impedance layers residing between a first higher-impedance layer and a second higher-impedance layer. Each of the one or more low-impedance layers may have a lower acoustic impedance than an acoustic impedance of the first higher-impedance layer or an acoustic impedance of the second higher-impedance layer. At least one low-impedance layer may have a thickness corresponding to a multiple of a half wavelength at a peak frequency of the acoustic resonator. The peak frequency may be within a frequency range from 1 MHz. to 20 MHz.

Abstract: A device may selectively listen for a tracking reference signal (TRS) during connected mode discontinuous reception (CDRx) based on whether the device is to switch between repeaters of a base station (such as during travel). A device may determine whether the device is in a high speed train (HST) scenario (such as based on a difference in frequency errors generated using a synchronization signal block (SSB) and generated using a TRS, based on a trajectory of a frequency error or a frequency error difference over time, based on instantaneous frequency errors, etc.). When the device is in a HST scenario, the device listens for a TRS during CDRx, and the device generates a frequency error using the TRS. When the device is not in a HST scenario, the device prevents listening for a TRS during CDRx (with a SSB received during CDRx to be used to generate a frequency error).

Abstract: A method of controlling an ultrasonic fingerprint sensor may involve receiving a first contact indication that a target object is in contact with a surface. The surface may be an ultrasonic fingerprint sensor surface or a surface of a device proximate an area in which the ultrasonic fingerprint sensor resides. In some examples, the method may involve: receiving a first removal indication that the target object has been removed from the surface; obtaining, subsequent to receiving the first removal indication, a first temperature measurement indicating a first temperature of at least a portion of the ultrasonic fingerprint sensor; determining at least one new ultrasonic fingerprint sensor parameter based, at least in part, on the first temperature; and updating at least one setting of the ultrasonic fingerprint sensor based, at least in part, on the new ultrasonic fingerprint sensor parameter.

Abstract: Systems, methods and apparatus for configuring a fingerprint sensor to operate in a capacitive sensing mode and an ultrasonic sensing mode are disclosed. A fingerprint sensor may be configured to operate in a capacitive sensing mode by driving a sensing electrode using a controller. In some implementations, an object positioned on or near the sensing electrode may be detected using the fingerprint sensor in the capacitive sensing mode, and the controller can drive electrodes of the fingerprint sensor differently to configure the fingerprint sensor to operate in an ultrasonic sensing mode. In some implementations, an applications processor may be instructed to authenticate a fingerprint of the object from image data obtained when the fingerprint sensor is operating in the ultrasonic sensing mode. In some implementations, a display of a mobile device containing the fingerprint sensor may be unlocked, or the mobile device may be woken up when the fingerprint is authenticated.

Abstract: A wearable otoscope may be capable of wireless or wired communication with a second device, such as a smart phone. Some dual-ear otoscope implementations may be provided in a headphone-like configuration, which may include a headband attachable to earbuds of the dual-ear otoscope. However, some alternative implementations do not include a headband. At least a portion of the dual-ear otoscope may be a disposable component in some examples. In some implementations, functionality of the dual-ear otoscope (such as an illumination angle of light, imaging functionality, etc.) may be controlled according to commands received from the second device. Some examples may include one or more additional sensors, such as temperature sensors.

Abstract: An optical touch sensor may include traces of photoconductive material formed on a substantially transparent substrate. Each photoconductive trace may be capable of responding to an incident light intensity increase on a portion of the photoconductive trace by increasing the number of charged carriers, thereby raising the electrical conductivity of that portion of the photoconductive trace. An incident light intensity decrease on a portion of the photoconductive trace will lower the electrical conductivity of that portion of the photoconductive trace. The corresponding changes in voltage may be measured by circuits that include conductive traces formed substantially perpendicular to, and configured for electrical connection with, the traces of photoconductive material. A diode (such as a Schottky diode) may be formed at the electrical connections between the conductive traces and the photoconductive traces.
