Abstract: A method watermarks speech data by using a generator to generate speech data including a watermark. The generator is trained to generate the speech data including the watermark. The training process generates first speech from the generator. The first speech data is configured to represent speech. The first speech data includes a candidate watermark. The training also produces an inconsistency message as a function of at least one difference between the first speech data and at least authentic speech data. The training further includes transforming the first speech data, including the candidate watermark, using a watermark robustness module to produce transformed speech data including a transformed candidate watermark. The transformed speech data includes a transformed candidate watermark. The training further produces a watermark-detectability message, using a watermark detection machine learning system, relating to one or more desirable watermark features of the transformed candidate watermark.

Abstract: This disclosure describes a rotational coupling mechanism for releasably coupling a device to a mounting platform. In one example, a user may nest a device within the mounting platform and perform a single rotation of the nested device to toggle between a locked position and an unlocked position. The user may continue the single rotation of the nested device, in the same clockwise or anticlockwise direction, to toggle the device from the unlocked position and back to the locked position. In a locked position, the device is restricted from translation relative to the mounting platform, however, the device may continue to rotate in a clockwise or counterclockwise direction to toggle between a locked and unlocked position. In an unlocked position, the device may disengage freely from the mounting platform and is thus subsequently free to move in any translational direction or about any rotational axis.

Abstract: Architected materials with superior energy absorption properties when loaded in compression. In several embodiments such materials are formed from micro-truss structures composed of interpenetrating tubes in a volume between a first surface and a second surface. The stress-strain response of these structures, for compressive loads applied to the two surfaces, is tailored by arranging for some but not all of the tubes to extend to both surfaces, adjusting the number of layers of repeated unit cells in the structure, arranging for the nodes to be offset from alignment along lines normal to the surfaces, or including multiple interlocking micro-truss structures.
