Abstract: A marching drum assembly of the present invention includes a supporter, at least an engaging element, at least a drum body, and a carrier. The engaging element includes a first and a second clipper boards which are parallel to each other, and a clipper trough is formed therebetween to receive a board-shape frame of the supporter. The engaging element also has a positioning element which is able to pivot relatively to the second clipper board. The positioning element is able to be fixed to the first clipper board after being pivoted toward the first clipper board. Thus, the two clipper boards are clamped tightly. Besides, one of the clipper boards connects with the drum body, and the carrier is capable of bearing the supporter. Thereby, the drum can be positioned at any preferred position on the frame, and easy adjustment and fixation can be achieved.

Abstract: A drum comprises a drum body made of at least one fiber layer. The drum body is provided with a drumhead at each of two opposite ends thereof. The drumheads are positioned on two reinforced frames disposed at both ends of the drum body by two drum hoops, so that the contact area between the drumheads and the drum body can be reduced through the reinforced frames. In addition, the reinforced frames reinforce the structure and maintain the shape of the drum body. Plural positioning screws are inserted through the periphery of the respective drum hoops, and the drum body is provided with plural fixing members to be screwed with the positioning screws. By such arrangements, the drum not only has the advantages of reinforced structure, light weight and easy production but exert a better resonance effect, making the sound produced by the drum more robust and powerful.

Abstract: A high speed orthogonal dense wavelength division multiplexing DWDM signal generator includes a multi-peak continuous wave signal generator responsive to a light source, an optical filter for separating multi-peaks of lightwaves from the generator; and a polarization multiplexing stage responsive to the multi-peaks of lightwaves from the optical filter for providing a polarization multiplexing optical signal. The generator includes a cascaded phase modulator and intensity modulator driven by a repetitive frequency (I) to generate multiple spectral peaks, each peak being modulated by an optical modulator driven by a respective baud rate (f baud/s) electrical signal.

Abstract: A method by an optical network unit ONU includes, for downstream transmission, using a first tunable laser for coherent detection on a sub-band basis to increase receiver sensitivity and reduce analog-to-digital conversion ADC and digital signal processor DSP requirements within the ONU, and for upstream transmission, using a second tunable laser and using an optical signal beating between the first and second tunable lasers to generate a tunable radio frequency RF signal source for upstream multi-band OFDMA signal generation thereby avoiding need for an otherwise more costly RF clock source within the ONU, enabling low-speed digital-to-analog conversion DAC operation and rendering the ONU colorless in both optical and radio frequency RF domains.
