Abstract: A method and system of selectively projecting images is disclosed. An illuminated area is created on a projection surface by directing a light source to the projection surface. The illuminated area is detected with a camera. Electrical signals are transmitted from the camera to the projector, the electrical signals being indicative of the position of the illuminated area in relation to the projection surface. Based on the received electrical signals, an image and a second image are projected on the projection surface. The image is projected on the illuminated area of the projection surface. The second image is projected on an area of the projection surface that is not illuminated by the light source. Applications of this method and system include the projection of background and foreground images creating the illusion of an x-ray beam, the projection of a normal image and an overblown image creating the illusion of a magnifying light beam.

Abstract: A method, apparatus, and article of manufacture provide the ability to display and use object manipulators in a computer graphics program. In some embodiments, an object manipulator (i.e., a button object manipulator or traditional object manipulator) is displayed on a graphics object and activated. In response to the activation, a property of the graphics object is directly modified. Various forms and properties of the object manipulator provide additional capabilities that may assist the user in the graphics program.

Abstract: A spring-biased pivoting squeegee 10 provides a head 12 pivotally attached to a handle 16. The head 12 is movable between a rest position, in which the head 12 is angularly displaced from the handle 16, and a biased position in which the head 12, handle 16, and wiping blade 14 are in linear relation. In the biased position, the wiping blade is maintained at an optimum angle for cleaning a glass surface even with the handle 16 held generally perpendicular to the glass. A spring 60 is fully contained in the head 12 and biases the head toward the rest position. A tension adjustment knob 80 in the head 12 permits adjustment of the spring 60 to a tension level according to the ergonomic requirements of a user. In a second embodiment of the invention an improved locking mechanism comprises a pivoting lock lever 260 held against the top wall 262 of a recess 264 in the head 202 of the squeegee by a retainer 278. The lock 260 is movable between locked and released positions.

Abstract: A sliding jogger comprises a fixed part 10 for securing to the frame 16 of a blanking tool and a sliding part 12 slidable on the fixed part. The two parts of the jogger are formed by stamping a respective blank from sheet metal and bending the blank.

Abstract: A surface-based interactive environment that utilizes low cost equipment to create a highly interactive environment for participants. The game can include electronic versions of traditional games, such as air hockey, football, soccer, and the like. The game can also include one or more electronically generated characters with whom the participants can interact. The system utilizes a high-mounted projector to create the game environment and/or generate the characters. A remotely mounted infrared light source and infrared camera are used to detect the participants as they move around within the interaction area of the game.

Abstract: A method, apparatus, and article of manufacture provide the ability to define a project in a computer graphics program. A project file is defined with general information regarding the project. A folder structure for the project is defined where one or more project drawing files are organized into various folders by drawing file type. A companion file for each project drawing file is defined with information to link each project drawing file to the project.

Abstract: A method, apparatus, and article of manufacture provide the ability to specify and maintain a “location” for an object in a drawing program. A drawing is obtained in a drawing program. One or more objects are obtained in the drawing program. In this regard, one or more of the is a collection of one or more graphical elements. For at least one of the objects, an automatic location property is defined. A value for the location property is obtained from property data of another object, area, or space where the object is “located” (which is based on the location property).

Abstract: An apparatus for interpolating an image from a plural number of image values for a display having an array of display pixels more numerous than the number of images. The apparatus includes a generating device, a designating device, and first and second applying devices. The generating device generates image signals based on image data representing an image of a living body and for designating an array of pixels based on the image signals. The designating devices designates as primary image pixels a limited plurality of display pixels within the array of pixels. The first applying device applies the image values each to a respective one or more of the primary image pixels.

Abstract: A network control unit for monitoring and controlling all of the operational components of a facility management system, the unit including a modular base frame having a wiring board assembly mounted on the back, a number of termination board assemblies mounted on the front of the frame and being operably connected to the wiring board assembly, one or more function modules, digital control modules, expansion modules, and a network control module are mounted on the front of the frame and operably connected to the wiring board assembly.
