Abstract: An optical coupling module includes a top surface, a bottom surface parallel and opposite to the top surface, a front side surface, and a rear side surface parallel and opposite to the front side surface. The bottom surface defines a bottom groove including a first optical surface. Optical coupling lenses are arranged on the first optical surface. The bottom groove further includes a mounting surface parallel to the first optical surface and perpendicularly connected with the front side surface. Grooves in the mounting surface receive and locate optical fibers, which intersect with a straight line along the optical axes of the optical coupling lenses, the straight line runs between the optical coupling lenses and the photoelectric conversion members.

Abstract: A lens includes a light incident surface and a light output surface. In a coordinate system, the light incident surface satisfies a formula (1): Z r 1 = c 1 ? r 1 2 1 + 1 - r 1 2 ? c 1 2 + u 1 2 ? ( 1 - u 1 2 ) 1 - r 1 2 ? c 1 2 ? ? m = 0 M ? a m ? Q m ? ( u 1 2 ) . c1 is a curvature of the light incident surface. r1 is a distance from the center of the lens to a joint point between the light input surface and a radius which is substantially perpendicular to the central axis of the lens. u1 is a normalized radius of the light incident surface. am represents the aspheric coefficient. Qm is a polynomial of order m and represents that the sum of am is equal to the sum of the root mean square of the slope of the light incident surface.

Abstract: A lens for an LED includes a top face, a bottom face, and a circumferential periphery interconnecting the top and bottom faces. The top face defines a recess therein. A concave wall defines a bottom of the recess. In cross section of the lens, the concave wall consists of two symmetrical curves extending outward and upwardly from a bottom tip of the recess to connect with the top face. Each curve is a part of a hyperbola. The cavity is for receiving an LED therein. The lens further forms a cone-shaped top wall enclosing a top of the cavity. Light emitted from the LED travels through the cone-shaped top wall to strike the concave wall and be reflected thereby to radiate sideward and downwardly. The sideward and downwardly reflected light then is reflected by a reflective coating on a substrate to illuminate upwardly.

Abstract: A text conversion method and a text conversion system are provided. A term mapping table recording a term mapping relationship between a source language and a target language is provided. A tokenization process is performed on a paragraph in the source language to obtain tokenization results. The tokenization results are compared with the term mapping table to determine each source language term in the paragraph is belonging to a first type or a second type. The source language terms belonging to the first type are converted into corresponding target language terms according to the term mapping table. Regarding each source language term of the second type, one of multiple corresponding candidate target language terms is selected as the target language term according to a co-occurrence relevance of relevant terms, wherein each relevant term is constituted by one candidate target language term and words before and after that in the paragraph.

Abstract: A translation system is provided. The system includes an input interface for receiving a term to be translated, a multi-language term processing module, a term correlation calculation module and an analysis module. The multi-language term processing module collects multi-language correlated terms corresponding to the term to be translated and language data sources, and establishes term pairs each including any two multi-language correlated terms having a relationship in translation. The multi-language correlated terms include at least the term to be translated and at least one candidate translated term in the target language. The term correlation calculation module calculates a term correlation value between the two multi-language correlated terms of each term pair and a self correlation value of each multi-language correlated term. The analysis module determines one of the candidate translated terms as the translation result term according to the term correlation values and the self correlation values.

Abstract: A multimedia storage card system includes a memory card; a dynamic switch coupled electrically and communicatively to the memory card; a first accessor coupled electrically and communicatively to the dynamic switch for accessing to the memory card, thereby storing data into and retrieving data from the memory card; and a second accessor coupled electrically and communicatively to the dynamic switch. Upon receipt of a first access signal transmitted from the second accessor, the dynamic switch determines whether the first accessor is in an idle condition. Upon detecting the first accessor is in the idle condition, the dynamic switch is switched to and in communication link with the second accessor, thereby transmitting the first access signal to the memory card and enabling the second accessor to access the memory card in order to store data into and retrieving data from the memory card.
