Abstract: A timepiece with a double-sided display, including a first display member and a second display member coaxial to the first display member and integral therewith with a first common arbor. The centers of mass of the first display member and the second display member are, in projection on a plane perpendicular to their common axis. The first display member and/or the second display member is arranged to display a visual animation, and is movable above a back, and, either above a mask partially and incompletely covering the back.

Abstract: A timepiece with a double-sided display, including a structure including, on a first side, a first display member, and, on a second side, a second display member coaxial to the first display member and integral therewith with a first common arbor, the centres of mass of the first display member and the second display member are, in projection on a plane perpendicular to their common axis, aligned with the projection of the latter or coincident therewith, the first display member and/or the second display member is arranged to display a visual animation, and is movable above a back, and, either above a mask partially and incompletely covering the back, leaving a visible area contiguous with a hidden area wherein the back is invisible to the user, or between the back and the mask, moving above the visible area or the hidden area depending on its angular position with respect to the common axis.

Abstract: Various embodiments of systems and methods to assess gesture inputs for performing usability testing of an application are described herein. In one aspect, a GUI associated with an application to be tested is presented. Gesture inputs from test participants to invoke execution of a task of the application using the GUI are recorded. Further, 3D coordinates corresponding to each of the recorded gesture inputs are determined And, the determined 3D coordinates are assessed to determine at least one intuitive gesture input to invoke execution of the task of the application.

Abstract: The present invention relates to a method for the cultivation of a mammalian cell in a cultivation medium of a cultivation vessel comprising adjusting the rate of a rotational movement of the cultivation vessel depending on the viable cell density in the cultivation medium.
