An audio-feature analyzer automatically detects points of change in audio signals to be processed. A central processing unit (CPU) obtains point-of-change information indicating positions of the points of change in the audio signals, and the point-of-change information is recorded on a data storage device. The CPU identifies point-of-change information in accordance with an instruction input by a user via a key operation unit, and audio data corresponding to the point-of-change information identified is located so that processing such as playback of audio data to be processed can be started therefrom.

The present invention relates to a method for thermally printing a pre-selected dye image (45) onto a three dimensional object (16). The method involves placing an image carrier sheet (24) containing a pre-selected dye image (45) over the object (16). A flexible membrane (26) is lowered over the object (16) and the image carrier sheet (24). A vacuum is established under the membrane (26) causing the image carrier sheet (24) to conform to the shape of the object (16). The membrane (26) or image carrier sheet (24) carry flexible heating elements (36), which are heated, to thermally transfer the dye image (45) onto the object (16). The flexible heating elements (36) can be made by etching an electrical circuit in a metal foil (34) which is bonded to a film substrate (30).

The present invention provides an apparatus and method for applying preselected dye images to three dimensional objects, having plastic outer surfaces, utilizing flexible carrier sheets bearing dyes in the mirror images of the preselected images, where the sheets are overlaid in registration with the objects and maintained in pressurized engagement therewith while the sheets and the objects are heated. The present invention includes a bed for receiving at least one three-dimensional object member thereon with a flexible dye bearing carrier sheet placed in registration on the object and a resiliently flexible membrane, which is positionable over the sheet on the member. A vacuum assembly of the apparatus is operable to evacuate the area between the membrane and the bed in order to draw the membrane into pressurized engagement with the flexible sheet on the member thereby drawing the flexible sheet around the various surfaces of the three dimensional object. Radiant heating elements are operable both to preheat the carrier sheet, improving its flexibility and to heat the membrane after the vacuum assembly has been actuated, whereby the dye on the sheet is applied to the surfaces of the object to produce the preselected image thereon.

The present invention is directed to a method for producing a high gloss coating on a printed surface. In the present method, an aqueous coating composition is deposited onto a surface to be printed using a blanket roller coating face which is a low energy, non-stick, smooth surface profile. In the present method, simultaneous with the deposition of aqueous coating onto a substrate, or shortly thereafter, pressure either alone or in combination with heat may be applied to the coating in order to create a substantially tack-free surface conforming to the surface of the coating face.
