Abstract: Systems and methods are disclosed for capturing stabilized images. Motion of the mobile device is determined so that the relative position of the lens and image sensor may be adjusted to compensate for unintended motion. The relative position of the lens and image sensor may be periodically reset in response to a synchronization signal in between capturing images.

Abstract: A robotic cleaning appliance includes a housing, surface treatment item, surface type detection sensor, and processor. The sensor emits sonic signals toward a surface being traversed and receives corresponding returned signals from the surface. The returned signals are used for surface type detection and include directly reflected primary returned signals and multi-path reflected secondary returned signals which return at a later time than the primary returned signals. The processor selects a window of time after transmission of a sonic signal such that the returned signals in the window comprise at least a portion of the secondary returned signals, wherein the window is related to round trip time-of-flight of the returned signals; processes the returned signals falling in the window to achieve a reflectivity metric; compares the reflectivity metric to a stored value; and based on the comparison, determines which surface type of a plurality of surface types has been detected.

Abstract: Systems and methods of correcting for signal drift in optical image stabilization of a portable device. An accelerometer is used to obtain an acceleration signal corresponding to acceleration of the portable device. A gravity component is removed from the accelerometer signal to obtain a proper acceleration signal. A double integration is performed on the proper acceleration signal to obtain a translation signal. A drift component of the translation signal is estimated. The estimated drift component is used to generate a drift correction signal. A phase compensation signal is determined based on a plurality of phase responses of a plurality of components of the optical image stabilization system. The drift correction signal and the phase compensation signal are applied to an actuator controller which controls movement of a lens within the portable device as part of the process for optical image stabilization.

Abstract: A method, system and computer readable medium for Ultrasound contact tracing comprising receiving one or more advertise messages determining a base station from the one or more advertise messages wherein the base station generates a broadcast order from at least the one or more advertise messages. A broadcast order is determined and an ultrasound message is sent according to the broadcast order. A detection period for ultrasound messages is initiated according to the broadcast order and a user may be notified of a detected ultrasound message.
