  • Publication number: 20140204588
    Abstract: A light emitting device (LED) luminous flux converting lens including a bonding portion that bonds the LED luminous flux converting lens to a supporting plate to fix the LED luminous flux converting lens. The LED luminous flux converting lens includes a bonding portion that protrudes from a boundary of an upper surface in a horizontal direction, and the bonding portion includes a first portion and a second portion having different thicknesses. The LED luminous flux converting lens includes a bonding portion that protrudes from a portion of a boundary of the upper surface in a horizontal direction. A luminous flux efficiency of the LED luminous flux converting lens may be increased by reducing loss in a luminous flux due to the bonding portion.

  • Patent number: 8665208
    Abstract: Disclosed is a product having an absolute positioning pattern on its surface and a method for forming the absolute pattern. The product includes first cells displaying coded binary data or displaying coded data expressed in terms of at least three digits; second cells displaying data coded in a manner different from the first cells or having no data; and a unit cell pattern formed by a group of at least a predetermined number of the first and second cells. The combination of data corresponding to the first cells within the unit cell pattern indicates an absolute coordinate of the corresponding unit cell pattern, and the unit cell pattern is differentiated from other adjacent unit cell patterns by the second cells within the unit cell pattern. The disclosed product and method require a smaller amount of operation to calculate the coordinate value compared with the prior art, but can display a broader position.

  • Patent number: 8269720
    Abstract: The present invention relates a coordinate input device to input a variety of job commands, diagrams or characters, and to store or output the input data. More particularly, the present invention provides an input device for recognizing hybrid coordinates and a method of operating the device. The input device uses an absolute coordinate recognition method and a relative coordinate recognition method in a combined fashion as a coordinate recognition method for inputting the track of the characters or diagrams. By doing so, input coordinates are converted into absolute coordinates, and the tracks of handwritten characters and diagrams are stored as the converted absolute coordinates such that the tracks are displayed on a display of the input device or on a monitor of an information terminal connected to the input device.

  • Patent number: 8270775
    Abstract: A system and method of recognizing absolute coordinates are provided. The absolute coordinate recognition system includes: a pattern recording medium in which each cell is diagrammatized, and a predetermined microcode is allocated to the pattern formed by each arrangement of the diagrammatized cells; a pattern sensing unit recognizing the microcode by sensing the pattern; and a signal processing unit calculating the position of the pattern sensing unit on the pattern recording medium, from the sensed pattern. By constructing the simpler patterns of the pattern recording medium, the absolute coordinate recognition system and method therefor enable imaging system and image sensor with not-high resolutions to recognize the patterns.
