  • Patent number: 11776534
    Abstract: Techniques for responding to a user input using a device-executable intent are described. A user may speak, to a device, an input corresponding to a first natural language understanding (NLU) intent executable by a speech processing system. The speech processing system may determine a device type corresponding to the device and, based on the device type, determine a data subscription is required to execute the first NLU intent. Thereafter, the speech processing system may determine a second NLU intent that is executable by the device and that results in the output of similar content to the execution of the first NLU intent. The speech processing system then directs the device to execute the second NLU intent.

  • Patent number: 11687635
    Abstract: This document describes techniques and systems that enable automatic exposure and gain control for face authentication. The techniques and systems include a user device initializing a gain for a near-infrared camera system using a default gain. The user device ascertains patch-mean statistics of one or more regions-of-interest of a most-recently captured image that was captured by the near-infrared camera system. The user device computes an update in the initialized gain to provide an updated gain that is usable to scale the one or more regions-of-interest toward a target mean-luminance value. The user device dampens the updated gain by using hysteresis. Then, the user device sets the initialized gain for the near-infrared camera system to the dampened updated gain.
