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 selectively process material on a processing surface of a printing form to create a fine structure or pattern for images or text. At least one fiber laser comprising a pump source and a laser fiber is provided. A laser gun is mounted adjacent the printing form and has at least a focusing optics. The fiber laser outputs a laser beam which is diffraction-limited to permit the focusing optics to focus the laser beam onto the processing surface of the printing form as a spot having a spot size sufficiently small to process the processing surface to create the fine structure or pattern images or text.

The present invention is based on the finding that a reconstructed output channel, reconstructed with a multi-channel reconstructor using at least one downmix channel derived by downmixing a plurality of original channels and using a parameter representation including additional information on a temporal fine structure of an original channel can be reconstructed efficiently with high quality, when a generator for generating a direct signal component and a diffuse signal component based on the downmix channel is used. The quality can be essentially enhanced, if only the direct signal component is modified such that the temporal fine structure of the reconstructed output channel is fitting a desired temporal fine structure, indicated by the additional information on the temporal fine structure transmitted.

An interposer includes a substrate made of an inorganic material; a through wiring including conductors embedded in through holes; and an upper wiring and (or) a lower wiring. The through wiring, the upper wiring and the lower wiring are respectively formed on preliminary wiring patterns that are additionally simultaneously or sequentially formed on layers made of an insulating material applied to at least wiring forming parts of the substrate, and are formed with a metal mold itself used for forming the preliminary wiring patterns or layers made of a wiring material applied by a printing operation, a plating operation or a deposition on the preliminary wiring patterns formed on the layers of the insulating material by transferring a fine structure pattern of the metal mold.

The present invention provides a cochlear stimulation system and method for capturing and translating FTS in incoming sounds and delivering this information spatially to the cochlea. An embodiment of the system may comprise an FTS estimator / analyzer and a current navigator. An embodiment of the method of the invention can comprise: analyzing the incoming sounds within a time frequency band, extracting the slowly varying frequency components and estimating the FTS to obtain a more precise dominant FTS component within a frequency band. After adding the fine structure to the carrier to identify a precise dominant FTS component in each frequency band (or stimulation channel), a stimulation current is steered to the precise spatial location on the cochlea that corresponds to the dominant FTS component, the steering accomplished by delivering non-simultaneous stimuli through at least two electrodes.

The invention discloses a novel fine metal mask plate for producing an organic light emitting diode (OLED) display panel and a fabrication method of the novel fine metal mask plate. The novel fine metal mask plate comprises a border formed by a plurality of through holes formed in a metal substrate, wherein a layer of fine mask is electroformed on the upper surface of the border, so that the fine mask and the border are combined into a whole; the fine mask divides a pattern area and a border area, on which a part with a fine structure is formed; the through holes in the pattern area and the border correspond to each other. The fabrication method comprises the following steps: A, preparing the metal substrate, namely carrying out rough shape cutting on an invar alloy plate or a stainless steel plate, so as to accord with the design size and form the metal substrate; B, fabricating the fine mask, namely coating a photoresist layer on the metal substrate, developing required patterns on the photoresist layer on the metal substrate, and orderly electroforming a metal substrate layer and a metal layer with a low coefficient of thermal expansion, so as to form the fine mask of the mask plate; and C, etching the substrate, namely dividing the pattern area on the refine mask, etching off the metal substrate in a district corresponding to the back part of the pattern area by a chemical etching method, so as to form the through holes, and leaving an external border and an internal partition frame, so that the external border and the internal partition frame jointly support the fine mask.

The present invention discloses of binaural stimulation in a neural auditory prosthesis. Binaural acoustic signals are generated that represent sound associated with a user's left and right ears respectively. Based on the binaural acoustic signals, corresponding binaural stimulation signals are generated for electrical stimulation of auditory nerve tissue of the user, wherein the binaural stimulation signals each include a fine structure component with periodic characteristics and interaural time difference (ITD) information. A phase jitter component is added to the binaural stimulation signals to reduce the periodic characteristics of the fine structure component while preserving the interaural time difference (ITD) information.

An ultra-fine microfabrication method using an energy beam is based on the use of shielding provided by nanometer or micrometer sized micro-particles to produce a variety of three-dimensional fine structures which have not been possible by the traditional photolithographic technique which is basically designed to produce two-dimensional structures. When the basis technique of radiation of an energy beam and shielding is combined with a shield positioning technique using a magnetic, electrical field or laser beam, with or without the additional chemical effects provided by reactive gas particle beams or solutions, fine structures of very high aspect ratios can be produced with precision. Applications of devices having the fine structures produced by the method include wavelength shifting in optical communications, quantum effect devices and intensive laser devices.
