  • Motor deflection monitoring for unmanned aerial vehicles
    Patent number: 9828095
    Abstract: Deflection of a rotor of a motor, such as a brushless motor, of an unmanned aerial vehicle (“UAV”) during operation may cause the magnets coupled to the interior surface of the rotor to move or walk down the surface, imbalancing the motor and potentially creating an unsafe flying condition for the UAV. The described methods and apparatus monitor rotor deflection of the motor during operation and alter one or more flight characteristics of the UAV if the deflection exceeds a tolerance range. By altering flight characteristics, external forces acting on the motor may be reduced, thereby reducing the deflection of the rotor.

  • Ahead of time compilation of content pages
    Patent number: 9830307
    Abstract: Systems and methods are described which provide improved memory and resource allocation for content pages accessed using a browser. A content page may be accessed and compiled into machine code, such as executable files or an application. The machine code may then be executed on a user device in a process separate from the browser to cause display of the content page, such as in a standalone application. Content pages may be pre-compiled and provided in response to user requests to access the content pages. A content page may be compiled faster than the browser may process the native content page, and the compiled machine code may require less memory than the native content page and associated resources. In some embodiments an intermediary system may be used to perform content page compilation and may provide the compiled machine code, instead of the native content, to the user device.

  • Multichannel acoustic echo cancellation with unique individual channel estimations
    Patent number: 9832569
    Abstract: A multi-channel echo cancellation system that dynamically adapts to changes in acoustic conditions. The system does not require a sequence of “start-up” tones to determine the impulse responses. Rather, the adaptive filters approximate estimated transfer functions for each channel. A secondary adaptive filter adjusts cancellation to adapt to changes in the actual transfer functions over time after the adaptive filters have been trained, even if the reference signals are not unique relative to each other.
