Abstract: An FSM data structure is encoded by generating a transition unit of data corresponding to each transition which leads ultimately to a final state of the FSM. Information about the states is included in the transition units, so that the encoded data structure can be written without state units of data. The incoming transition units to a final state each contain an indication of finality. The incoming transition units to a state which has no outgoing transition units each contain a branch ending indication. The outgoing transition units of each state are ordered into a comparison sequence for comparison with a received element, and all but the last outgoing transition unit contain an alternative indication of a subsequent alternative outgoing transition.

Abstract: Input image data define an input image that shows a perimeter relationship representation, such as a Venn diagram or statechart. The representation includes a perimeters feature that satisfies a constraint on perimeters. The constraint can include a perimeter size criterion that distinguishes perimeters from labels. Or the constraint can include an enclosing perimeter criterion requiring a connected component within each perimeter and a perimeter label criterion requiring a label for each perimeter. The constraint can also include an empty perimeter criterion to distinguish empty perimeters from labels. The input image data are used to obtain perimeters data indicating parts of the input image that satisfy the constraint. The perimeters data are used to obtain relationship data indicating a relationship between distinctions represented by the perimeters.

Abstract: A graphical editing system is provided which creates a "place-holder" that holds or suspends a complex gesture or complex menu selection before committing to the command. Such a place-holder acts as a virtual stylus, i.e. as if the user was actually holding the stylus to the screen just prior to committing to the command. The virtual stylus thus allows the user to execute other arbitrary drawings or menu commands or gestures while the original complex command is suspended. The user can then return to the complex command he/she chooses and remove the place-holder to commit to the command or cancel the command if desired. The virtual stylus can take on many forms, e.g., a hand with a pointed finger, an icon or any other desired indicator, and the virtual stylus can be created by any user action, e.g., an actuated stylus button, pressure sensitive display surface or by sensing the time during which the stylus remains stationary on the display screen. The virtual stylus can be removed in basically the same way.

Abstract: A method for processing images for printing includes the steps for each separation, making a pixel level determination of marking material coverage, based on the number of pixels within a given area that are turned on; if a determination is made that too much marking material will be placed within the given area, using a random number function for turning off a fraction of pixels in the area to reduce the amount of marking material that will be used for the given area; and to preventing artifacts from occurring in the pixel reduction step by utilizing a processing order through each given area which tends to randomize the turn off effect. Additionally, the results of the determination are compared for each separation, to determine that the turnoff result allows at least one corresponding pixel among each of the separations to be turned ON.

Abstract: An interactive processor-controlled system for entering and storing user information about an event that is being concurrently recorded in real time correlates the user information to user-requested addresses, such as time values stored with the recorded signals. The system includes a recording device for producing signals indicating recorded event data that includes periodic addresses, each of which indicates a portion of the recorded signals. An address source, such as a clock, is connected for providing address values to both the processor and the recording device. Using a pen-based user interface in one embodiment of the system, the system user specifically requests an address value in order to correlate user information to the signals being concurrently recorded. In response to a request for an address, the system establishes a spatial region on the display, called a time zone, into which the system user may enter information, in the form of handwritten strokes, about the event.

The light transmissive plates can be optical filters that also one used to separate the clustered light beams based upon their wavelength and/or polarization.

Abstract: A piezo-active charge retentive member, such as a photoreceptor, has a grounded electrode layer separating a photoreceptive layer and a piezo-active layer. External vibration sources become unnecessary since supplying an A.C. voltage across the piezo-active layer to the grounded electrode layer causes the piezo-active layer, and thus the entire photoreceptor, to vibrate. Vibration of the photoreceptor causes a carrier bead bouncing effect where carrier beads from the developer collide with the photoreceptor in the development area. The carrier bear bouncing effect increases the number of carrier bead-toner-photoreceptor contact events during development of the photoreceptor's latent image.
