Abstract: Approaches are described for generating an audio signal that mimics speech captured a computing device. An input audio signal (e.g., a speech signal) can be transformed from the time domain into another domain, to generate one or more audio signal segments, where each segment can correspond to a window of time. The device can then determine, for each audio signal segment, a feature characteristic of the audio signal, such as a phoneme. Each one of segments can be mapped, based at least in part on the respective feature characteristic, to a model audio signal. The device can then generate an output audio signal including each model audio signal as determined by the mapping, where the output audio signal is in a sequence associated with the input audio signal.

Abstract: A rotatable building structure (10) contains a vertical central core (14) for supporting suspended floor units (12) surrounding the core.

Abstract: Various embodiments enable additional content or features to be displayed to a user in response to detecting one eye of the user being closed either as a wink or for a duration of time. In one example, the additional content is graphical overlay, such as a menu containing selectable graphical elements to perform functions related to an application, game, or content, of global navigational features of the computing device in general, or to alternate views, features, or supplemental content for an application or game currently being displayed on a computing device. In one example, the overlay may be displayed only as long as the user keeps one eye closed or, alternatively, the user could wink to display the overlay and provide some other input to remove the overlay.

Abstract: The invention provides a method of automating the classification of a diamond gemstone. An infra-red absorption spectrum of the gemstone is provided. Features corresponding to absorption by water and intrinsic absorption by a diamond lattice are subtracted from the absorption spectrum. The spectrum is analysed to identify predetermined absorption features corresponding to lattice defects in the diamond. The gemstone is classified according to the intensities of the predetermined absorption features. The results of the classification are saved in a database.
