Title: Network switching device and network switching method
Inventor: KATAYAMA TAUL
IPC: H04L12/54
Filed: 2003-01-29
Abstract: A network switching device is provided which offers priority control of packets, increases the usage ratio of a buffer storing received packets, and enables the reduction of component costs. Under the control of a buffer control circuit (3), received packets (10) are entered to appropriate buffers according to their destination networks.

The buffer control circuit (3) creates transmission queues (4-1) to (4-n) in the buffers (1-1) to (1-n), respectively, to accommodate a plurality of groups of packets each falling under a different priority class. When writing a received packet (10) into a buffer, the buffer control circuit (3) consults the priority determination circuit (2) in order to control the order of pending packets in the corresponding transmission queue, so that the given packet (10) will be transmitted next to the last entered packet among those with the same priority.

Title: Tapped antiparallel hairpin-comb filters for microwave applications
Inventor: CHEN KUO-CHI
IPC: H03H7/01
Filed: 2003-01-30
Abstract: Tapped antiparallel hairpin-comb filters utilize two sets of hairpin (i.e., folded) half-wavelength microstrip or stripline resonators arranged side-by-side, but with opposite direction for these two sets. The input/output terminals of the filter are formed by tapped lines, respectively. The coupling regions between resonators extend parallel to the sides of the resonators with the same orientation for each set of hairpin resonators. Two sets of hairpin resonators are arranged in the opposite direction to each other to form an antiparalleled hairpin-comb filter. The coupling effects between these two resonator sets can reduce the couplings between resonators and then produce a compact filter structure having a narrow band filter response. The structure can also produce poles of attenuation adjacent to the passband, especially enhance the cutoff characteristic of a filter at passband edges.

Title: System capable of measuring five degrees of freedom signals
Inventor: JIUE WEN-YU
IPC: G01B11/00
Filed: 2003-03-31
Abstract: There is provided a system capable of measuring five degree of freedom signals, which utilizes a laser beam to be injected to a reflective mirror and then reflected to a grating for generating two positive and negative first-order diffractive light rays, which are received by two sets of semi-reflective mirrors to be split into two sets of reflective light and transmissive light. After the reflective light is injected into an beam splitter, a lens set and an electro-optical diode array, the measurement standard is changed from the wavelength into grating constant to obtain a set of shift freedom degree displacement in the movement direction. In addition, the split two sets of transmissive light are injected into two sets of two-dimensional position sensor detectors. The grating will change the direction of the diffractive light ray due to the swing of the movement direction, thereby obtaining a set of degrees of freedom displacement in grating surface direction and the displacement of degrees of freedom surrounding three-axis rotation angle, so as to achieve a system capable of measuring five degrees of freedom signals.
