    • Methods and apparatus include a handheld printer manipulated back and forth by an operator during use to print an image. An inkjet printhead of the printer has a plurality of fluid firing actuators arranged in a substantial column. A controller communicates with the printhead to identify active actuators given to fire at a particular time during use to print the image. However, to prevent unsightly print quality from occurring during overlapping adjacent print swaths, for example, certain of the identified actuators are prevented from firing. Especially, actuators in the column further from a center of the column fire less frequently than those closer to the center. A position sensor is also used to locate the printhead relative to the image. The controller correlates the position to the printhead and actuators and fires the active actuators or not.
    • 方法和装置包括在使用期间由操作者在打印图像期间来回操作的手持式打印机。 打印机的喷墨打印头具有布置在实质柱中的多个流体喷射致动器。 控制器与打印头进行通信,以识别在使用期间特定时间给予火灾的主动执行器以打印图像。 然而,为了防止在重叠的相邻打印条带期间发生不好的打印质量,例如,某些所识别的致动器被防止燃烧。 特别地,柱中更远离柱的致动器比靠近中心的致动器的频率更低。 位置传感器也用于相对于图像定位打印头。 控制器将位置与打印头和执行器相关联,并激活主动执行器。

    • Methods and apparatus include a handheld printer manipulated back and forth by an operator during use to print an image on a media. The media includes reference indicia upon which users maneuver the printer whenever a location of the printer is unknown or needs updating or validating. A controller of the printer correlates the location of a printhead to the image and when lost communicates to a direction indicator to provide user notification of where to move the housing to reacquire the location. Embodiments of the reference indicia include guide and location patterns, with the guide pattern pointing to the location pattern. Other indicia include related tick marks of substantially equal size and shape with substantially equal spacing there between. Supply items for applying on the media include a substrate with reference indicia thereon that matches stores reference indicia in the printer.
    • 方法和装置包括在使用期间由操作者来回操作的手持式打印机,以在媒体上打印图像。 介质包括参考标记,用户在打印机的位置未知或需要更新或验证时操纵打印机。 打印机的控制器将打印头的位置与图像相关联,并且当丢失时与方向指示器通信以向用户通知移动壳体的位置以重新获取位置。 参考标记的实施例包括引导和位置图案,其中引导图案指向位置图案。 其他标记包括基本相同尺寸和形状的相关刻度线,其间具有基本相等的间距。 用于在介质上施加的供应物品包括其上具有参考标记的基板,其与打印机中的参考标记相匹配。

    • The present invention provides a learning environment that presents information in an organized fashion with defined objectives using an extension of current 3D online technology. By combining 3D virtual space technology with additional asynchronous and synchronous communications features, a content rich learning environment can be created that allows students more realistic interactions than those provided by currently deployed systems. In addition, the system allows for the overlay and integration of 2D, text-based, and audio-based learning tools both within and outside the 3D environment and provides an interface with convergence technology such as cell phones, pagers, hand held computers, etc as well as collaborative tools such as presentation of overheads, computer software slide presentations such as MICROSOFT POWERPOINT, whiteboard, virtual network computing (VNC), and for class lectures, whiteboard, virtual network computing (VNC), and other collaborative tools layered into the 3D environment.
