Abstract: A noise suppressor includes a first differential-mode transmission module, a second differential-mode transmission module and a common-mode absorption module. The first and second differential-mode transmission modules are configured to receive a differential signal at one of the first and second differential-mode transmission modules, and output the differential signal at the other of the same. The common-mode absorption module is electrically connected to a reference node, and is configured to absorb common-mode noise of the differential signal from at least one of the first differential-mode transmission module or the second differential-mode transmission module.

Abstract: A leather inspection apparatus is provided for detecting inconsistencies on both upper and lower surfaces of a hide. It includes a first camera assembly movably coupled to a support frame and capable of movement along the upper surface of the hide and a second camera assembly movably coupled to the support frame and capable of movement along the lower surface of the hide. A computing device is coupled to the first camera assembly and the second camera assembly, such that the first camera assembly detects the locations of inconsistencies in the upper surface of the hide and the second camera assembly detects the locations of inconsistencies in the lower surface of the hide. The computing device digitally stores the locations of the inconsistencies of the upper surface of the hide and the locations of the inconsistencies of the lower surface of the hide.

Abstract: Embodiments of the present disclosure provide a two-phase process for searching root causes of a yield loss in a production line. In a first phase, an interaction between two process tools, that between two parameters, or that between one process tool and one parameter that is likely to cause the yield loss is identified. In a second phase, a threshold of the parameter that is likely to cause the yield loss and is obtained from the first phase is identified. In each phase, two different algorithms can be used to generate a reliance index (RII) for gauging the reliance levels of their search results.

Abstract: Systems and methods are provided for collecting three-dimensional surface data of a lasted shoe upper that is mated with a sole that is configured for the lasted upper. The mated three-dimensional data is used with three-dimensional data of the lasted shoe upper in an unmated configuration with the sole to determine a location of an edge defined by the intersection of the lasted upper and the sole when mated. The bite line identifies an edge where the upper and a sole assembly will intersect on a finished shoe, which may represent a bounding line for application of adhesive to the lasted upper for boding the sole thereto.

Abstract: A filter includes shunt circuits coupled between a reference node and each of an input port, an output port, a first node, and a second node. Resonant networks are coupled between the input port and the second node, and between the first node and the output port. Storage element circuits are coupled between the input port and the first node, and between the second node and the output port. The shunt circuits have an equivalent shunt circuit frequency response that partly defines a high passband frequency of the filter, the resonant networks have an equivalent resonant network frequency response that partly defines a low passband frequency of the filter, and the storage element circuits have an equivalent storage element circuit frequency response that defines a stopband frequency of the filter between the low passband frequency and the high passband frequency.

Abstract: A testing device utilized in a testing apparatus includes a top guiding board having top penetrating openings, a bottom guiding board disposed at one side of the top guiding board and having bottom penetrating openings, and elastic contact structures disposed between the top guiding board and the bottom guiding board. A testing device offset (represented by d2) exists between the top guiding board and the bottom guiding board. Each elastic contact structure has a tip section, a body section, and a tail section in sequence.

Each elastic contact structure has a target elastic contact structure offset (represented by d1), in which d1 and d2 satisfy the following equation: d2=d1±50˜200 ?m.

Abstract: A conditionally visible bite line may be demarcated on a shoe upper using at least one of a fluorescent or an Infrared (IR)-responsive material. Such a conditionally visible bite line may be observable only under particular conditions, such as when illuminated by an ultraviolet light source or an IR light source, as appropriate. A light may be projected to intersect the conditionally visible bite line under conditions rendering the conditionally visible bite line detectable. The intersection(s) of the projected light and the conditionally visible bite line may be used to create a virtual bite line for use in generating a tool path to process the surface of a shoe upper bounded by the conditionally visible bite line.

Abstract: A method for locating critical control points on a part or combination of parts during a manufacturing process involves mating, directly or indirectly, a jig extension to the part or parts. A pattern on the jig extension defines an origin point that is used to track the position of the part or parts during manufacturing, such as during location-sensitive operations. The jig extension may be a shoe last extension which connects to a shoe or shoe component via a shoe last.

Abstract: A method for automatically choosing a communication network is applicable to a mobile device. When receiving a communication request for a contact from a user interface, a processing unit determines a status of a network card module according to the communication request. When the network card module is enabled, the network card module sends a network packet and receives a corresponding response packet to determine whether the network card module is connected to the Internet. When the network card module is connected to the Internet, the network card module sends an inquiry packet to a voice over internet protocol (VoIP) proxy server and receives a corresponding response packet to determine whether the contact is online. When the contact is online, the network card module carries out the communication request through the VoIP proxy server. Otherwise, the communication request is carried out by a cellular phone module.

Abstract: A method for sampling coordinates of a touched point on a touch panel, includes the steps of: (a1) detecting a touched point at a low detection frequency to obtain two touch coordinates sequentially in time series; (a2) calculating a distance between the two touch coordinates; (a3) determining whether the distance between the two touch coordinates is greater than a first threshold distance; (a4) detecting a touched point at a high detection frequency to obtain a subsequent touch coordinate in time series; (a5) calculating a distance between two touch coordinates sequentially in time series at the high detection frequency; (a6) determining whether the distance obtained in the step (a5) is less than a second threshold distance; and (a7) detecting a touched point on the touch panel at the low detection frequency when the distance is less than the second threshold distance in the step (a6).
