Manufacturing and assembly of a shoe or a portion of a shoe is enhanced by automated placement and assembly of shoe parts. For example, a part-recognition system analyzes an image of a shoe part to identify the part and determine a location of the part. Once the part is identified and located, the part can be manipulated by an automated manufacturing tool.

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.

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.

A control circuit is developed to adaptively operate a power converter at quasi-resonance (QR) and in a continuous current mode (CCM) to achieve high efficiency. The control circuit includes a PWM circuit generating a switching signal coupled to switch a transformer. A signal generation circuit generates a ramp signal and a pulse signal. The pulse signal is generated in response to the ramp signal for switching on the switching signal. A feedback circuit produces a feedback signal according to an output load of the power converter. The feedback signal is coupled to switch off the switching signal. A detection circuit is coupled to the transformer for generating a valley signal in response to the waveform of the transformer. The valley signal is further coupled to generate the pulse signal when the ramp signal is lower than a threshold. The level of the threshold is correlated to the feedback signal.

A surface mount contact includes a conducting pin having a shank, a first end at one end of the shank and second end at the other end of the shank, a first annular flange extending around the periphery of the shank and spaced between the first end and the second end and a second annular flange extending around the periphery of the shank and spaced between the second end and the first annular flange, and a thermoplastic connection member joined to the second end of the conducting pin and spaced from the second annular flange at a predetermined distance so that there is a room for the user to judge the connection status and quality between the conducting pin and the thermoplastic connection member during surface mounting, assuring bonding stability.

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.

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.
