Abstract: A method of processing uncorrelated data from at least one multiple-contact tracking system is provided. The method identifies which of a plurality of contacts being tracked that the uncorrelated data is most likely to be associated with. By combining correlation with reassessment processing, correlation errors can be reduced or minimized. A threshold test (e.g., bearing test) is used to screen or coarsely filter the data while a comparison scoring test is used associate the uncorrelated data with one of the contacts. The same threshold test and comparison scoring test are used for both correlation and reassessment processing.

Abstract: The present invention provides a method for processing color image data for printing on an inkjet printer to reduce intercolor bleeding in an image recorded on a receiving medium. The method receives a target pixel comprising multiple separation pixels, wherein each separation is associated with a separate color plane and has at least three states, a first state corresponding to depositing no ink drops, a second state corresponding to depositing one ink drop, and a third state corresponding to depositing more than one ink drop. The method further includes determining if the target pixel is within a black border region near a black/color interface or within a color border region near a black/color interface.

Abstract: A system and method which enables the location and orientation of an image to be determined without introducing scanning artifacts into the rendered image. The system utilizes a separate set of sensors on a scanning bar that are sensitive to a wavelength of light outside the range of wavelengths of the typical sensors found on the scanning bar, such as red, green, or blue. Moreover, the system includes a light source which is capable of emitting the wavelength of light that is outside this range of wavelength of light. Thus, whenever the additional set of sensors detect light, the system would determine that the light was due to a scanning artifact, such as a hole, rip, or dog ear in the original document being scanned.

Abstract: A fuser baffle which helps to minimize or eliminate sheet wrinkle by a fuser. A small “saddle” is added to the center section of the inlet to the fuser on the baffle surface which last contacts and controls the sheet before entry into the fuser nip. The saddle removes most of the corrugation along approximately 90 to 95% of the centermost portion of the sheet. Any remaining corrugation at the inboard and outboard ends is removed by the fuser flare. The baffle is applicable to any fusing device which uses localized pressure to fix an image to a sheet.

Abstract: A device for providing an RF signal burst to an external load includes a voltage-controlled oscillator to generate a drive signal having a frequency f.sub.VCO fixed by an oscillator control signal. An RF driver stage coupled to the external load receives the drive signal and generates an RF signal burst in response to the drive signal. A current transformer coupled between the RF driver stage and the external load senses the current in the RF driver stage and generates a reference current having the same phase as the sensed current. A phase detector receives the reference current along with the drive signal and generates a phase detection signal that provides a measure of the phase of the current in the RF driver stage with respect to the drive signal. The phase detection signal can be used to adjust the oscillator control signal to drive the oscillator frequency to a desired value.

Abstract: An apparatus and method for correcting top edge sheet misregistration using a sensor array. An array sensor is placed in the paper path prior to transfer. A signal is generated indicating the position of the sheet. As a function of the signal the print controller causes the image to be exposed and developed on the photoreceptor in alignment with the sheet position. The aligned image is then transferred to the sheet.

Abstract: A method to shape a transmit beam pattern of a transmitter array. A basel time delay/phase coefficient is set for each transmitter. A plurality of beam pattern intensities are iteratively generated using the set of baseline time delays/phase coefficients and a plurality of sets of adjusted time delays/phase coefficients. Each beam pattern intensity has a unique set of time delays/phase coefficients associated therewith. Each one of the sets of adjusted time delays/phase coefficients differs from the set of baseline time delays/phase coefficients by only one time delay/phase coefficient. Each beam pattern intensity is compared with the optimal beam pattern intensity to determine which one of the set of unique time delays/phase coefficients minimizes a difference between the optimal beam pattern intensity and a corresponding one of the plurality of beam pattern intensities.

Abstract: A method for manipulating a three-dimensional sub-volume within a graphical display is disclosed and includes selecting an option from a menu screen to relocate or re-size a three-dimensional sub-volume within the graphical display, and upon selecting the option to relocate or re-size, proceeding with the following. A cursor is placed on either the sub-volume or a selected corner of the sub-volume within the graphical display, a selected one of a left and a right mouse buttons is depressed, and the sub-volume is dragged to a relocation area or resized within an "x-y" plane and/or a "z" plane of the graphical display according to depression of the selected mouse button and placement of the cursor. When the selected one of the left and right mouse buttons is released, the x, y, and z-coordinates of the relocation area and/or resizing are locked. The sub-volume is, therefore, manipulated within a three-dimensional frame of reference by controlling the mouse.

Abstract: A demodulation system and method is used in a sensor system, such as a fi optic sensor system, that senses optical signals and modulates a phase generated carrier having a carrier frequency .omega..sub.c to form a modulated carrier. The modulated carrier is preferably undersampled at three times the carrier frequency (3.omega..sub.c), thereby maximizing the sensors' demodulated bandwidth relative to the sensors' sampling frequency. The undersampled, modulated carrier is orthogonally demodulated by multiplying the undersampled, modulated carrier by cos(.omega..sub.c (t.sub.o)) and sin(.omega..sub.c)(t.sub.o)) to extract even and odd harmonic components of the signal of interest.

Abstract: A method and apparatus of printing with a liquid ink printhead ejecting ink in swaths on a recording medium to form an image including a plurality of dots deposited at pixel locations of a scanline. The printer deposits a plurality of dots at adjacent pixel locations on the scan line during non-consecutive swaths of the printhead to form the image. Dot interaction between dots is minimized so that no two dots are deposited adjacent to each other in consecutive depositions of the dots of consecutive swaths of the printhead. Reduction of ink bleeding, printhead signatures such as banding, and other defects caused by clogged nozzles of the printhead are reduced.

Abstract: A system for generating a wide-angle, forward-looking bathymetric map of an region ensonified by single ping. A transmitter generates a large angle transmit pulse. An array of acoustic transducer elements operates to transmit the pulse, receive acoustic return signals and convert the returns into digital acoustic data. A receiver matched filters, shades and steers the data through a series of horizontal angles. For each horizontal angle steered to, the receiver generates vertical beams and identifies detections as those vertical beams having magnitudes greater than a detection threshold. Vertical beam forming and detection identification is repeated for each time slice in a series of time slices over the ping cycle. The identified detections are refined using a curve fitting analysis and stored in equal angular vertical bins. A bottom profile is generated from the refined angles and magnitudes.

Another layer is an acoustically transparent wiring assembly that provides electrical connection to each acoustic sensor. A third acoustically transparent layer is a planar array of signal processing circuits coupled to the wiring assembly for processing electrical signals generated by the acoustic sensors. Each signal processing circuit resides within an area that is in geometric correspondence with a respective one acoustic sensor. Each signal processing circuit can include a preamplifier, an analog-to-digital converter and a digital multiplexer.
