Abstract: An optical transmission device includes: a control module generate a control signal output which includes a slope adjust signal and a bias voltage offset adjust signal according to an input signal indicating a dispersion amount an electrical level adjust signal; a multi-level pulse amplitude modulator; and an asymmetrical optical modulator which is controlled by the slope adjust signal to be operated at one of a positive slope and a negative slope of a transfer function of the asymmetrical optical modulator itself, and is controlled by the bias voltage offset adjust signal of the control signal output to offset a bias voltage point of the asymmetrical optical modulator itself from a quadrature point of the transfer function, and modulates the multi-level pulse amplitude modulation signal to an optical signal to generate an optical modulate signal having a chirp.

Abstract: A double-sided floorboard assembly includes one or multiple hook members affixed to a support frame bar on a bearing surface, and floor blocks arranged on the support frame bar. Each floor block has opposing front and rear side edges, opposing top and bottom surfaces respectively connected between the front and rear side edges, a first groove and a second groove located on the front side edge, a first rib formed on the front side edge between the first and second grooves, a third groove and a fourth groove located on the rear side edge. and a second rib formed on the rear side edge between the third and fourth grooves. The first rib of one floor block front is superimposed on the second rib of another floor block to define a first gap therebetween.

Abstract: The present invention discloses a method for producing graphical indicators and interactive systems for utilizing the graphical indicators. On the surface of an object, visually negligible graphical indicators are provided. The graphical indicators and main information, i.e. text or pictures, co-exist on the surface of object. The graphical indicators do not interfere with the main information when the perception of human eyes are concerned. With the graphical indicators, further information other than the main information on the surface of object are carried. In addition to the main information on the surface of object, one is able to obtain additional information through an auxiliary electronic device or trigger an interactive operation.

Abstract: A floor assembly includes a plurality of boards and bases. Each board is provided on the bottom surface thereof with a sliding groove. Each base includes a main body, a positioning member, and first and second buckling members. The positioning member is slidably disposed in the sliding groove of the board. The first buckling member is located at the left side of the main body and has a buckling block and a notch. The second buckling member is located at the right side of the main body and has an accommodating space and a protrusion. The adjacent bases are connected with each other in a way that the buckling block is disposed in the accommodating space and the protrusion is embedded in the notch. As a result, the floor assembly is simplified in structure and assembling process, thereby convenient in construction and stable in structure.

Abstract: An outdoor floor covering includes a plurality of planks, a plurality of bases, and at least a fastening element. A positioning portion of each base is slidably disposed in a sliding groove of each plank. Adjacent ones of first sidewall surfaces of the bases are engaged with each other through engaging portions. Adjacent ones of second sidewall surfaces of the bases abut against each other through protruding and dent portions. At least a fastening element is engaged and connected between adjacent ones of the second sidewall surfaces of the bases. Hence, the outdoor floor covering of the present invention enables quick assembly and prevents the planks and bases from undergoing displacement horizontally or vertically. Accordingly, the outdoor floor covering is quick and convenient to lay, exhibits satisfactory structural stability, and enhances pedestrian safety.

Abstract: A graphical indicator provided on the surface of an object to represent index information includes a content part and a header part. The content part is spread with a plurality of micro-units and divided into a plurality of state zones. Each state zone is spread with one micro-unit and equally divided into multiple hypothetical sections. The micro-unit is placed in any of the hypothetical sections to form different candidate states. The header part is spread with a plurality of micro-units that are specifically arranged to provide header information used to recognize the graphical indicator.
