In atomic physics, the fine structure describes the splitting of the spectral lines of atoms due to electron spin and relativistic corrections to the non-relativistic Schrödinger equation. It was first measured precisely for the hydrogen atom by Albert A. Michelson and Edward W. Morley in 1887 laying the basis for the theoretical treatment by Arnold Sommerfeld, introducing the fine-structure constant.

Multi-tactile display haptic interface device
InactiveUS20030210259A1Input/output for user-computer interactionCosmonautic condition simulationsFine structureTouch Perception
A tactile array is integrated with a large scale force-feedback device. Under software control, the large scale force-feedback device provides large scale shape information while the tactile display provides fine structures and surface texture. In a virtual reality environment, the concept of a "tactile map" is employed. A tactile map provides surface details and is rendered by the tactile array. Tactile maps may be based on actual object surface properties, or they may be arbitrarily generated based on the application. In operation, the effect of colliding with a object is produced and the point of contact is noted. The corresponding location on the tactile map is identified, and the surface features are rendered on the tactile array. Moving the point of contact changes the corresponding portion of the tactile map being rendered.

A system and method for preserving temporal and spatial resolution in complex sounds for poor performing patients having high stimulation thresholds is described. The system and method employs two or more adjacent electrode contacts to deliver concurrent stimulation. This concurrent delivery of stimuli creates a high current field intensity that overlaps between individual current fields generated by the two or more adjacent electrodes and which individual fields are summed to create an overlapping field that has a higher current field intensity than a single current emanating from an individual electrode. The use of this method reduces or eliminates the need to increase either the stimulus current amplitude or to increase the pulse width, both of which may cause loss of system resolution, i.e., loss of fine structure information that is used to resolve complex sounds such as music.
