摘要:
An apparatus for analyzing a physical signal representing a physical phenomenon is provided. The apparatus comprises an analog-to-digital converter, a slope calculator, a local extrema identifier, a residual signal constructor and an intrinsic mode function (IMF) extractor. The analog-to-digital converter is used to convert the physical signal into a plurality of data points. The slope calculator is used to calculate slope of each data point. The local extrema identifier is used to identify a plurality of local extrema of the slopes. The residual signal constructor is used to construct a residual signal of the physical signal from the data points corresponding to the local extrema of slopes. An IMF extractor is used to extract an intrinsic mode function indicative of an intrinsic oscillatory mode in the physical phenomenon by subtracting the residual signal from the physical signal. A method for analyzing a physical signal representing a physical phenomenon is provided.

An integrated transformation apparatus is provided. The apparatus includes a first multiplexer, a second multiplexer, and a transformation unit. The first multiplexer retrieves point data from columns or rows of a multi-dimensional matrix and input data. The second multiplexer retrieves transformation coefficients corresponding to the point data. The transformation unit transforms data blocks of the multi-dimensional matrix to a plurality of sub data blocks according to the input data, the point data, and the transformation coefficients.

An image processing method and a system for processing the same are provided. The image processing method includes the following steps. A first image having several first areas and a second image having several second areas are provided. Each first area has a first feature point having the largest or the smallest grey value in the first area. Each second area has a second feature point having the largest or the smallest grey value in the second area. A first relationship between the first feature points and a second relationship between the second feature points are created. The first and the second feature points are paired by a microprocessor according to the first and the second relationship.

Aspects relate to systems, methods, and apparatus for a zoned vacuum tool comprised of independently operable vacuum sources provided a vacuum force to segregated zones. A vacuum force is generated in connection with a first zone independently of an activation or deactivation of vacuum force generation associated with a second zone. Therefore, a single vacuum tool can selectively apply a vacuum force to material portions, which allows for control as to which material portions are manipulated by the vacuum tool.

Manufacturing of a shoe is enhanced by creating 3-D models of shoe parts. For example, a laser beam may be projected onto a shoe-part surface, such that a projected laser line appears on the shoe part. An image of the projected laser line may be analyzed to determine coordinate information, which may be converted into geometric coordinate values usable to create a 3-D model of the shoe part. Once a 3-D model is known and is converted to a coordinate system recognized by shoe-manufacturing tools, certain manufacturing steps may be automated.

Aspects of the present invention relate to systems and apparatus for a multi-aperture vacuum tool that is comprised of a distributed vacuum tool that has a number of apertures distributed across an area for manipulating material portion, such as textile, mesh, cloth, and foam. The multi-aperture vacuum tool is also comprised of a refined vacuum tool. The refined vacuum tool generally has a couple of apertures that allow the refined vacuum tool to manipulate smaller portions of material than that which are handled by the distributed vacuum tool. Further, it is contemplated that an affixing tool, such as an ultrasonic welder, is also incorporated with exemplary aspects of the multi-aperture vacuum tool.

A sport ball may have a plurality of panels that are joined at seams to form a casing. The panels may include a thermoplastic polymer material applied to an interior side of the panels, and the thermoplastic polymer material may be heat-activated to extend across the seams. The ball may further include a bladder within the casing and an intermediate layer located between the casing and the bladder. The thermoplastic polymer material may also be heat-activated to bond with the intermediate layer or casing.
