Abstract: Techniques for video manipulation based on an immersive video experience including rotation are disclosed. Parameters pertaining to a video are determined. Second parameters pertaining to a video display are determined. A minimum scale value is calculated to inscribe a rectangle within an oval based on a height and a width of the video. A height and a width of the video display define the rectangle. A gravity sensor input is preprocessed using a low-pass filter before using it to determine the minimum scale value. The video is preprocessed using a video inset and a viewport inset. The video can be trimmed, and the rectangle can be scaled. A rectangular portion of the video is rendered on the video display wherein the rectangular portion is on or inside the boundaries of the oval.

Abstract: The video playback technology disclosed herein gives fullscreen immersive experience to users when they watch videos on mobile devices used to watch the video. Specifically, an implementation of the technology disclosed herein gives a continuous all-time immersive experience by treating the screen of the mobile device as a window to watch a wide-angle video, and by keeping the video's relative angle to gravity unchanged while users rotate or tilt their mobile devices. In one implementation, the video also zooms in/out of the display during rotation of the smartphones, to give users a sense of getting closer/farther to the video. One or more implementations disclosed herein use inputs from gravity sensors including magnetic sensors, gyroscope, accelerometer, etc., to determine the amount of zooming in/out and shifting for the video in response to various movements, such as rotate, move, and tilt, of the video display device by the users.

Abstract: A generator includes a bio-compatible substrate onto which one mechanical generating unit is disposed. A plurality of elongated piezoelectric fibers each have a first end that is in electrical communication with a first electrode and an opposite second end that is in electrical communication with a second electrode. An insulative layer covers the first electrode, the second electrode and the elongated piezoelectric fibers. A third electrode and a fourth electrode are each disposed on the bio-compatible substrate opposite from the mechanical generating unit. A proton conducting member is in contact with both the third electrode and the fourth electrode. A glucose catalyzing enzyme is electrically coupled to the third electrode. An oxidase enzyme is electrically coupled to the fourth electrode. The third electrode is in electrical communication with each first electrode and the fourth electrode is in electrical communication with each second electrode.
