摘要： A device in a wireless network receives signals and determines media access control (MAC) slot boundaries of the received signals. The MAC slot boundaries are averaged in time, and a local slot boundary is modified in response thereto. The local MAC slot boundary is modified by less than ten percent of a short interframe space until the local MAC slot boundary is within one orthogonal frequency division multiplexing (OFDM) cyclic prefix duration of the averaged MAC slot boundaries.

摘要： In general, in one aspect, the disclosure describes an apparatus that includes a sample averager to construct a preliminary estimate of a spatial covariance matrix from a received communications signal. A time-domain filter with Cholesky decomposition is used to decompose the preliminary estimate of the spatial covariance matrix into product of an upper triangular matrix and complex conjugate of the upper triangular matrix. The time-domain filter with Cholesky decomposition is also used to filter the upper triangular matrix and construct an updated estimate of the spatial covariance matrix using the filtered upper triangular matrix.

摘要： A resonant power converter is disclosed with a driving circuit generating a switching signal connecting power to a resonant tank circuit, with a voltage monitoring circuit measuring a voltage output and a load current. A micro-controller is operable with a control circuit for multiple step sampling with the switching signal at a switching frequency to settle the resonant circuit determined from the voltage output and load current. A fast load transient response at a high frequency with the resonant circuit provides the multiple step sampling to ensure enough time for micro-controller to calculate. Optimal trajectory control facilitates a burst mode of high frequency with the resonant circuit using adaptive multiple step sampling for an on-time to extend the burst operation range. A soft start-up process uses the micro-controller processing in multiple stages.

摘要： Systems and methods for applying cosmetics are provided using an incoherent light projector shining light on the face, capturing the reflected light using a camera and the projector, communicating with the camera and the projector and a structured light depth processor to generate a depth image output. A control device communicates with the structure light depth sensor to receive the output, to receive the face profiles and generate motion trajectory commands, and a robot communicates with the control device to receive the commands to apply the cosmetics to the face in accordance with the face profiles. Methods for applying the cosmetics include receiving a face profile, receiving a depth sensor input representing a face, extracting face features, matching the face profile to the face features, and generating a guide or outputting robot trajectory to apply the cosmetics.
