Abstract: In some embodiments, a method receives a plurality of inputs for a video for a plurality of times at a prediction network that includes a plurality of cells. The prediction network generates a plurality of predictions of watch behavior of the video for the plurality of inputs at the plurality of cells. The plurality of predictions predicts a performance of the video on a video delivery service for the plurality of times. Actual performance data generated from users viewing the video on the video delivery service is received before a time. A time series residual for at least a portion of the plurality of predictions is generated from the actual performance data and prior predictions. The portion of the predictions after the time using values in the time series residual is adjusted. The adjusted predictions of watch behavior are output for the video.

Abstract: A system for wireless power transmission may include one or more charging panels and one or more powered devices. The charging panel may include a pilot analysis circuitry, processor and power transmitter. The pilot analysis circuitry may be configured to analyze the magnitude and phase of a pilot signal from the powered device, based on which the processor may be configured to determine a complex conjugate of the pilot signal. And the power transmitter may be configured to cause radiation of a focused wireless power beam to the powered device in accordance with the complex conjugate of the pilot signal and via one or more antenna elements. The charging panel may be one of a plurality of spatially-distributed charging panels each of which includes respective antenna elements that may form an array of antenna elements configured to collaboratively radiate wireless power as a distributed, retro-reflective beamformer.
