Abstract: The disclosed sole structure of the present invention comprises a first sole layer, a second sole layer and spikes. The first sole layer has an upper surface and a lower surface, a plurality of openings penetrating the upper surface. The spikes arrange at a side close to the lower surface and correspond to the openings. Each of the spikes has a gap with the corresponding opening. The second sole layer envelops the first sole layer. Wherein a portion of the second layer is attached to the upper surface, and another portion of the second sole layer is attached to the lower surface, and the second sole layer located to a side of the lower surface extends into the openings and connects to the spike.

Abstract: An article of footwear and a knitted component thereof are provided. The article of footwear includes a shoe upper and a sole structure fixed to the shoe upper. The shoe upper defines a shoe cavity for a foot to be inserted thereinto. The shoe upper is formed by the knitted component and includes a plurality of upper regions. The knitted component is a two-dimensional structure knitted from at least one yarn and includes a plurality of knitted regions respectively corresponding to the plurality of upper regions. Each of the plurality of upper regions has a stretch ratio to its corresponding knitted region of the plurality of knitted regions. The number of stitches in each of the plurality of knitted regions is proportional to its corresponding stretch ratio, so when the foot is inserted into the shoe cavity, courses and wales formed by the at least one yarn in the plurality of upper regions are substantially orthogonal.

Abstract: Based upon an item master, the present invention establishes a 3-tier data structure containing a bill of material (BOM), an item master, and a related information object (a file or datum) and integrates various information management software modules or information objects stored in the BOM, the item master and the related information object in the same database into an information module. For the information modules in different databases, the present invention further utilizes the tree structure of the item master to link required information together, forming an integrated information structure that enables each information object to communicate with one another and share information among databases.

Abstract: An information transacting mechanism between a provider and a customer is provided. The information transacting mechanism comprises an information server controlled by the provider. An original information box is extracted from the information server. A tool server provides tools when instructed by the provider. A tool-added information box is resulted from the original information box by packing tools therein via the tool server and sent to the customer for the customer to access the data contained in the tool-added information box.

Abstract: A method and structure for managing information objects is disclosed herein, wherein an item master is provided to logically link a BOM (bill of material) to one or more databases, thereby constituting an information relationship between the BOM and the one or more databases. In accordance with a version management rule, the user can rebuild a new item master and its logic link between the BOM and related one or more databases so as to maintain information correctness and manage the versions of the BOM.

Abstract: This invention concerns a method for driving multiple poles (rotors and stators) motors. A driving waveform with the best efficiency according to electromagnetic analysis is used to avoid unnecessary magnetic saturation effect to reduce iron loss of the motor. Since the smallest possible current is used to generate maximum torque, copper loss is reduced so the motor is not heated and its efficiency is increased. In addition, the driving method divides magnetic poles into 3N parts (N is an integer) so that poles at opposite corners has the same waveform and the same torque. This implementation avoids generation of static force, effectively generates torque and avoids vibration and noises. It is an energy saving, effective and stable way of driving motor.
