    • A handheld portable printer includes members and a handle that are joined together to form a generally O-shaped device. The members provide a rigid and strong structure and an area for housing a projector to project an image on the print surface of the image to be printed. The bottom member houses a pair of absolute position sensors spaced apart and aligned upon the longitudinal axis on the bottom of the handheld portable printer. A controller is associated with the absolute position sensors to produce precise position information. The controller uses the precise position information to control the projection of the image to be printed and the printing of pixels by the print head. In one embodiment, the print head is controlled such that each pixel is printed at least twice. The present invention also includes a number of novel methods including: a method for printing an image with a handheld printer, a method for projecting an image to be printed, and a method for registering a location of a printer and portions of a printed image.
    • 手持便携式打印机包括连接在一起以形成大致O形装置的构件和手柄。 这些构件提供刚性和坚固的结构以及用于容纳投影仪的区域,用于在要打印的图像的打印表面上投影图像。 底部构件容纳一对绝对位置传感器,其间隔开并在手持式便携式打印机的底部上的纵轴上对准。 控制器与绝对位置传感器相关联,以产生精确的位置信息。 控制器使用精确的位置信息来控制要打印的图像的投影和通过打印头的像素的打印。 在一个实施例中,打印头被控制成使得每个像素被打印至少两次。 本发明还包括许多新颖的方法,包括:用手持式打印机打印图像的方法,用于投影要打印的图像的方法,以及用于记录打印机的位置和打印图像的一部分的方法。

    • A system for using accelerometer-based detection of physical movement for document sharing provides easy and intuitive ways to securely share documents, even without passwords, between computing devices. The system of the present invention includes: at least two computing devices that each have a motion detection device capable of detecting sudden movements and generating a unique signature. The unique signature can then be used to generate signatures or shared secrets for controlling the transfer of data between devices. The motion detection device is capable of detecting sudden movement such as the tapping of the two computing devices together, tapping a stack of computing devices, tossing a computing device in the air. The system may optionally include an intermediary device such as a server for transferring the documents or files between computing devices such that only a small decryption key and file pointer is needed to share records between computing devices. The present invention also includes a novel method for accelerometer-based detection of movement for transferring data between computing devices.

    • A system including a Multi Function Printer/Product/Peripheral (MFP) and a portable computing device adapted to allow automatic copying of documents by the MFP from the portable computing device. The portable computing device includes a display, a plurality of sensors for detecting light, a light detection module and a page changing module. The sensors are positioned to detect light from the MFP and trigger a page change automatically. The MFP in accordance with the present invention includes a scanner with a platen, a page change detection module, an image processing module, a device identification module, and a document matching & retrieval module. The page change detection module is adapted to receive the images presented by the portable computing device on the platen of the scanner for copying. The page change detection module detects changes and causes the MFP to scan and output a copy.
