  • Publication number: 20240145624
    Abstract: A pixel herein includes a color panel, a light emitting diode (LED) panel, and an adhesive layer disposed between the color panel and the LED panel. The color panel includes a transparent layer, a plurality of sub-pixel isolation structures, and a plurality of black matrix structures disposed between the plurality of sub-pixel isolation structures and the transparent layer. The sub-pixel isolation structures define a plurality color conversion wells of plurality of sub-pixels. A color conversion material is disposed in the color conversion well. The plurality of black matrix structures define a plurality of color resist wells of the plurality of sub-pixels. A color resist is disposed in the color resist wells. The LED panel includes a plurality of micro-LEDs disposed on a backplane. The plurality of micro-LEDs correspond to a sub-pixel.

  • Publication number: 20130207573
    Abstract: The present invention relates to a synchronous control apparatus for speed-reducing DC motor, comprising a speed-reducing DC motor and a controller, wherein said speed-reducing DC motor comprises a motor and a speed reducer. Said speed-reducing motor is equipped with a speed detecting module to detect the actual rotational speed. Said controller is equipped with a storage unit to save reference rotational speed values. Said speed detecting module is linked to the controller which can vary the supply voltage to the speed-reducing DC motor while the actual rotational speed differs from the reference speed value.

  • Publication number: 20120087537
    Abstract: A system and method for business card information reading and managing comprises a scanner which is optional and can provide dark background, a preprocessing module, a host computer with data storage, input/output (I/O), and display devices, an information extracting module, optical character recognition (OCR) engine, an image-processing (IP) engine, an information organizing module, all connected to the host computer to work together. On top of the system is the dataflow logic, i.e. the method, which guides all the business card information reading and management in a sequence of steps. The method is supported mainly through the software (SW) running on the host computer, with a GUI to interact with end users and provides functions like scanning/loading images and managing result.

  • Patent number: 5540440
    Abstract: A baseball board game comprising three game boards, two of which represent offensive and defensive players, the third of which represents the field of play. The field of play board is generally in the shape of a baseball diamond, but is divided into vertical and horizontal polar coordinates. The field of play also has zones upon it to account for scoring, balls, strikes and player positioning. A ball shaped marker is used to designate the position of the ball on the field and player markers designate the position of players on the field. The game may be played with either specially marked dice and one player board or with the use of the two player boards. Each of the player boards can be interchangeably used as the offensive or defensive team. Each player board illustrates a zone for an air or ground ball, a six by six coordinate system for placement of a hit ball, a bad ball zone and a stolen base zone.
