A method includes receiving a first output from a first sensor of an electronic device and receiving a second output from a second sensor of the electronic device. The first sensor has a first sensor type and the second sensor has a second sensor type that is different from the first sensor type. The method also includes detecting a gesture based on the first output and the second output according to a complementary voting scheme that is at least partially based on gesture complexity.

Gesture detection based on information from multiple types of sensors

Various techniques and apparatuses are disclosed that provide for pixelated display modules that integrate an ultrasonic fingerprint or biometric sensing capability. In some implementations, the ultrasonic fingerprint sensor and the display components of the display module may share a common backplane. In some implementations, the ultrasonic fingerprint sensor may share a flex cable with other components in the display module. In some implementations, the ultrasonic fingerprint sensor may leverage conductive traces on a cover glass used to provide for touch input to the display module.

Display with peripherally configured ultrasonic biometric sensor

The disclosure is directed to storing trace information. An aspect includes determining whether or not a pen is within a threshold distance of the touchscreen, storing trace information generated by a user's touch in a touch buffer if the pen is not within the threshold distance of the touchscreen, and clearing the touch buffer and storing trace information generated by the pen in the touch buffer if the pen is within the threshold distance of the touchscreen.

Storing trace information

A method and system for resynchronizing an embedded multimedia system using bytes consumed in an audio decoder. The bytes consumed provides a mechanism to compensate for bit error handling and correction in a system that does not require re-transmission. The audio decoder keeps track of the bytes consumed and periodically reports the bytes consumed. A host microprocessor indexes the actual bytes consumed since bit errors may have been handled or corrected to a predetermined byte count to determine whether resynchronization is necessary.

Method and system for error robust audio playback time stamp reporting

Methods and apparatus for generating an anti-noise signal and equalizing a reproduced audio signal (e.g., a far-end telephone signal) are described, wherein the generating and the equalizing are both based on information from an acoustic error signal.

Systems, methods, devices, apparatus, and computer program products for audio equalization

Systems and methods for performing an action based on a detected gesture are provided. The systems and methods provided herein may detect a direction of an initial touchless gesture and process subsequent touchless gestures based on the direction of the initial touchless gesture. The systems and methods may translate a coordinate system related to a user device and a gesture library based on the detected direction such that subsequent touchless gestures may be processed based on the detected direction. The systems and methods may allow a user to make a touchless gesture over a device to interact with the device independent of the orientation of the device since the direction of the initial gesture can set the coordinate system or context for subsequent gesture detection.

Systems and methods for performing a device action based on a detected gesture

Voice activity detection using multiple microphones can be based on a relationship between an energy at each of a speech reference microphone and a noise reference microphone. The energy output from each of the speech reference microphone and the noise reference microphone can be determined. A speech to noise energy ratio can be determined and compared to a predetermined voice activity threshold. In another embodiment, the absolute value of the autocorrelation of the speech and noise reference signals are determined and a ratio based on autocorrelation values is determined. Ratios that exceed the predetermined threshold can indicate the presence of a voice signal. The speech and noise energies or autocorrelations can be determined using a weighted average or over a discrete frame size.

Multiple microphone voice activity detector

The embodiments provide systems and methods for touchless sensing and gesture recognition using continuous wave sound signals. Continuous wave sound, such as ultrasound, emitted by a transmitter may reflect from an object, and be received by one or more sound receivers. Sound signals may be temporally encoded. Received sound signals may be processed to determine a channel impulse response or calculate time of flight. Determined channel impulse responses may be processed to extract recognizable features or angles. Extracted features may be compared to a database of features to identify a user input gesture associated with the matched feature. Angles of channel impulse response curves may be associated with an input gesture. Time of flight values from each receiver may be used to determine coordinates of the reflecting object. Embodiments may be implemented as part of a graphical user interface. Embodiments may be used to determine a location of an emitter.
