Abstract: Hardware and/or software systems, devices, networks, and methods of the present invention enable ornamental devices, and interactive electronic devices in general, to generate and react to stimulus from other devices. In various embodiments electronic devices generate one or more pseudo-stimuli and stimuli and/or react to the stimuli generated by other devices mimicking fireflies, other bioluminescent organisms, and other interacting organisms. Pseudo-stimuli generally simulates the physical stimulus of the organism. Whereas the stimulus may include naturally-occurring stimulus, as well as technology generated stimuli to increase system robustness. When a stimulus generated by a first electronic device is detected by one or more second electronic devices, the second devices may react in one or more different methods.

Abstract: According to an aspect, a device may include a first member, a second member, and a wrist mechanism disposed between the first member and the second member. The wrist mechanism may include a first cylinder portion coupled to the first member, and a second cylinder portion coupled to the second member. The first cylinder portion may be rollably engaged with the second cylinder portion such that movement of the first cylinder portion with respect to the second cylinder portion is configured to cause the first member to move in at least two directions with respect to the second member. The second cylinder portion may be positioned with respect to the first cylinder portion such that a longitudinal axis of the second cylinder portion is orthogonal to a longitudinal axis of the first cylinder portion.

Abstract: Part for a timepiece movement, made of a composite material comprising a rigid matrix and a forest of nanotubes contained in the rigid matrix.

Abstract: In a general aspect, an apparatus can include a substrate and a porous layer disposed on the substrate, the porous layer including a plurality of silica nanotubes. The silica nanotubes of the porous layer can be solid, partially hollow and/or hollow elongate silica structures.
