Abstract: One aspect of the invention involves a writing tablet comprising a housing having a writing surface and internal logic placed within the housing and situated below the writing surface. The internal logic includes imaging sensor, a light source and a controller. The imaging sensor is adapted to capture a location and orientation of each line segment forming a graphic image. The light source is adapted to produce a light beam adjusted for display on the writing surface. The controller is adapted to control performance of an event upon the light beam crossing a line segment of the graphic image.

Abstract: A three-dimensional modeling system. The modeling system includes an antenna and a stylus. The stylus has at least one tag that communicates with the antenna to provide position signals of the tag, allowing the stylus to trace the surface of an object into a processor. The system may include more than one antenna, each producing an electromagnetic field within which the object to be modeled is positioned. The stylus may have two tags, which will allow derivation of orientation information from the position signals. The stylus may have a pressure-sensitive tip allowing the communication between the tag and the antenna to be controlled only when the stylus is in contact with the object to be modeled. The system may also have at least one tag attached to the object to provide more accurate information as to the position and orientation of the object relative to the points traced by the stylus. The stylus may also be used to trace an outline or other two-dimensional shape.

Abstract: A computer microscope system having a housing, imager circuit including an imaging device and support circuits, and optical unit is coupled to a computer system running a microscope control program to provide convenient imaging of objects at one or more magnification levels. The microscope control program provides control and user interface between the microscope, computer hardware and the user, thus allowing for easy manipulation of the microscope (and the images generated) by the user.

Abstract: Methods of providing user input to an interactive computer application using video input in association with touch input. The methods include generating a control view having a control image, wherein the control image is associated with an application command; generating a foreground view of a controlling entity superimposed on the control view, wherein an image location of the foreground view within the control view is indicative of a physical location of the controlling entity adjacent a touch input device; and producing an output capable of selecting the application command when the touch input device is activated by the controlling entity at the physical location where the foreground view is aligned with the control image. Machine-readable medium having instruction stored thereon capable of causing a processor to carry out the methods of providing user input. Apparatus adapted to carry out the methods of providing user input.

Abstract: A system creates a template for use with a number of colored pieces in a patterned children's game or similar application. The colored pieces are formed of a plurality of colors and at least one size. The system generates a digital image. The system then pixelates the image based on the number of colored pieces and the at least one size. The system then color adjusts the image based on the plurality of colors.

Abstract: A multi-processor programmable interrupt controller system which includes: an I/O interrupt controller for receiving interrupt requests from an I/O subsystem; multiple processor interrupt controllers, each associated with a specific processor for dispensing of accepted interrupts; and an interrupt controller bus primarily for the transmission of interrupt requests between interrupt controller units and for priority arbitration, using a standard message format and arbitration protocol.
