A mouse incorporating a camera captures an image of embedded data from a substrate under the mouse. The embedded data in the image is decoded to determine address or location information coded in the embedded data. Based on the decoded information and other user input signals, such as mouse button selection signals, the computer executes operations. The mouse also has a display controlled by the computer for providing visual feedback to a user. The display might generate an image of the substrate area under the mouse, making it appear to the user as if they are looking through the mouse directly onto the substrate. The display may also generate visual feedback regarding operations occurring in the computer, such as selection or other computer operations.

Method and apparatus for implementing a camera mouse

A camera pen is made from a pen-like housing contains a camera and has a button for sending a signal to a computer which directs the camera to capture an image. The pen-like housing includes landing gear on one end. The landing gear has an opening which forms a flat surface that is angled such that when a user places the camera pen on a surface, the angle at which the pen rests on the surface is ergonomically comfortable for the user. Furthermore, the camera is oriented toward the opening so that when the user presses the button indicating a desire to capture an image, the camera captures the image in the opening. By combining a camera with a pen-like device, the user can comfortably capture image information from a surface.

A method for refilling an ink cartridge which contains an elastic bladder within the ink reservoir cavity that is connected to outside pressure. The methodology of the invention teaches how to seal and unseal the bladder and ink regions in sequential steps and how to inject ink into the ink reservoir cavity so it may be re-used and not discarded.

An apparatus for imaging books or other bound documents with minimal stress being applied to the book structure, and for successively imaging and turning pages of a book without the need for manual intervention. The book imager includes a support, for placement of a book in an open position, an imager having opposed imaging surfaces capable of simultaneously imaging the entire exposed, facing adjacent pages of the book in a distortion preventing manner, and a page turner. The support and the imager are relatively movable toward and away from one another, from a first position in which imaging is effected, to a second position in which page turning is effected.

A kit for opening and sealing a cartridge having an interior ink reservoir coupled to an access port extending from a reference surface comprises a rigid plunger, a plate and a rigid spherical plug. The plate has one or more regions of varying thickness and a bottom surface which is complementary to the reference surface on the cartridge. The bottom surface of the plate may be matched to the reference surface of the cartridge in two distinct orientations such that a sealed access port may be opened, refilled and sealed with a rigid spherical plug by extension of the plunger through the plate in each orientation to a depth determined by the length of the plunger, the thickness of the plate in each orientation, the depth of the access port in the cartridge, and the diameter of the spherical plug.

Method for opening, refilling and sealing a cartridge

A method of refilling an ink jet cartridge with ink. The cartridge has a housing which encloses an internal ink reservoir extending between top and bottom ends thereof, an ink fill aperture extending through the housing near its top end, and a means for sealing the ink fill aperture. The cartridge further includes a bladder in the reservoir, an air port affixed to the top of the housing, and a spring means which biases the bladder toward a minimum volume state. According to the method, the cartridge is positioned with its top end above its bottom end, the ink fill aperture is unsealed, and the air port is sealed. The bladder is inflated to establish an internal volume in a predetermined range. Ink is then injected into the reservoir through the ink fill aperture. The ink fill aperture is then sealed, and the air port unsealed.
