Abstract: Method for dynamically controlling data paths of Machine-type-communication (MTC) local access device(s) are proposed along with a MTC gateway and a network device using the same method. In one embodiment, the proposed method may include following: a network device, receiving and storing capillary network information and MTC gateway interconnection information from at least one MTC server; combining the access network information with the capillary network information and the MTC gateway interconnection information to build an aggregated topology map; generating enhanced policy rules according to the aggregated topology map related to at least one capillary network; and respectively transmitting the enhanced policy rules to the interconnected MTC gateways.

Abstract: Substrate structures, liquid crystal display devices and methods of fabricating liquid crystal display devices. A substrate structure comprises a transparent substrate having an electrode layer thereon. A first alignment layer is formed on the transparent substrate. A second alignment layer is selectively formed on the first alignment, wherein alignment orientations of liquid crystal molecules on the first and second alignment layers are different.

Abstract: A light emitting diode (LED) package structure is disclosed. The LED package structure comprises a lead frame which has a chip carrier part, a pair of extended parts, a first electrode and a second electrode. The chip carrier part has an arc frame, a bulge, a first surface and a second surface. The extended part has a first side, a second side, a first top and a first bottom. The first side connects the arc frame of the chip carrier part. The arc frame electrically connects the first electrode. A heat dissipating material is placed on the second surface.

Abstract: The present invention may significantly reduce the number of iteration of the time recursive IFFT structure. First, the real and imaginary part of the input signal are modified based on the symmetric and anti-symmetric. Then, they are mixed together by an adder and fed into the lattice module. Next, an IFFT is performed on the modified input data sequence to generate a transformed sequence. Through the symmetric and anti-symmetric properties, the redundant terms may be eliminated.

Abstract: A vertical calibration method for a wire cut electric discharge machine includes selecting a known altitude for a reference point, marking down four different positions of the upper wire guide of the wire cut electric discharge machine at three different altitudes and reptitively moving the wire of the wire cut electric discharge machine being in contact with the reference point, measuring four different displacements of the upper wire guide when being in contact with the reference point, establishing an equation by using a principle of trianglation, and completing calculation of positions of the upper wire guide and the lower wire guide to finish calibration.

Abstract: A two screw double-stroke and screw differential-motion mechanism is applied in a standard mechanical interface. The two mechanisms are utilized for the correlation of transmission between screws and nuts and the screw differential-motion, so as to achieve more efficient positioning and clamp retrieval and placement.
