Abstract:

Various embodiments set forth systems and techniques for securing media content capture capabilities on a device. The techniques include receiving a frame of a media content item; determining whether the frame of the media content item is signed based on an analysis of one or more pixels of the frame; and when the media content is signed, removing one or more restrictions on one or more functions on the device based on whether the one or more pixels on the frame meet one or more conditions, wherein the one or more functions enable the device to perform one or more operations on the frame of the media content item.

Abstract:

A small scale, high speed turbomachine is described, as well as a process for manufacturing the turbomachine. The turbomachine is manufactured by diffusion bonding stacked sheets of metal foil, each of which has been pre-formed to correspond to a cross section of the turbomachine structure. The turbomachines include rotating elements as well as static structures. Using this process, turbomachines may be manufactured with rotating elements that have outer diameters of less than four inches in size, and/or blading heights of less than 0.1 inches. The rotating elements of the turbomachines are capable of rotating at speeds in excess of 150 feet per second. In addition, cooling features may be added internally to blading to facilitate cooling in high temperature operations.
