20110227937 | SYSTEM AND METHOD FOR FRAME BUFFER STORAGE AND RETRIEVAL IN ALTERNATING ORIENTATIONS - The present invention provides a method and apparatus for storing image data for successive frames in a frame buffer. Specifically, the method and apparatus allow for a display-sized frame buffer to be utilized where a host system provides image data in a format different from that which the display requires to be written to it while retaining the beneficial aspects of concurrent read and write operations from and to the frame buffer. Using this method a buffer controller receives image data from a host system in a first format (e.g. row-by-row) and writes it to the frame buffer in the first format. When the buffer is completely filled with the first frame, it is read out in a second format (e.g. column-by-column) by the buffer controller and provided to a display driver that writes the data to the display. As the first frame is read out in the second format, the buffer controller receives image data for a second frame from the host system in the first format, but rotates it before writing it to the frame buffer such that it is written to the frame buffer in the second format. This rotation allows the buffer controller to write to the frame buffer and the display driver to read from the frame buffer concurrently, despite the different image data format requirements of the host system and display. When the second frame is completely written to the buffer in the second format, the buffer controller then reads the buffer in the first format, and writes it to the display. At this point the process repeats. Thus, the benefits of concurrent read and write are preserved. | 2011-09-22 |

20110227987 | THERMAL INKJET PRINTHEAD FEED TRANSITION CHAMBER AND METHOD OF COOLING USING SAME - A thermal inkjet printhead and a method of cooling convectively cool the printhead with ink passing through a feed transition chamber. The thermal inkjet printhead includes a bridge beam and feed channels adjacent to the bridge beam. The printhead further includes a feed transition chamber between inputs to the feed channels and an ink reservoir. The ink flows through the feed transition chamber between the ink reservoir and the feed channels to convectively cool. The method of cooling includes providing the feed transition chamber and flowing ink through the feed transition chamber from the ink reservoir to the feed channels. The flowing ink establishes a temperature gradient between walls of the feed transition chamber and the ink. The temperature gradient facilitates convective cooling of the printhead. | 2011-09-22 |

20110227989 | METHOD OF ADJUSTING OPTICAL AXIS OF INK DROPLET DETECTING DEVICE, METHOD OF ASSEMBLING INK DROPLET DETECTING DEVICE, AND APPARATUS FOR ADJUSTING OPTICAL AXIS - After a light emitting element holder is rotated, it is detected from the output value of a position adjusting light receiving element that a light beam formed by light emitted from a light emitting element is incident on a positioning target provided in a light emitting element. The light emitting element holder is duly fixed to a base member. When the incidence of the light beam on the positioning target is not detected from the output value of the position adjusting light receiving element even though the light emitting element holder is rotated, a light receiving element holder is made to slide for height adjustment and the light emitting element holder is rotated again. The adjustment of the height of the light receiving element holder and the adjustment of the rotation of the light emitting element holder are repeated until the light beam is incident on the positioning target. | 2011-09-22 |
