  • Patent number: 5623558
    Abstract: A system for restoring images with undefined pixel values at known locations is described. The threshold value and a neighborhood configuration are defined and are used to restore the image. The neighborhood configuration defines a geometric region, typically a fixed number of pixels, surrounding the target pixel. The threshold value specifies a number of pixels in the neighborhood configuration for which pixel values are known. In our system, for each pixel in one of the unknown regions an analysis is performed over the entire area defined by the neighborhood configuration. If the threshold number of pixels within that region is known, then the value of the unknown pixel is calculated. If the threshold value is not achieved, then analysis proceeds to the next pixel location. By continuing the process and reducing the threshold value when necessary or desirable, the complete image can be restored.

  • Patent number: 5546502
    Abstract: A system is described for automatically invoking computational resources without intervention or request from a user of the system. In the system a query-free information retrieval system is described in which the exact technical documentation contained in existing user or other technical manuals is provided to a user investigating apparatus having a fault. The user enters symptoms based upon the user's analysis of the apparatus, and in response the system provides information concerning likely faults with the apparatus. As the symptoms are entered, the relative value of individual faults is determined and related to the symptoms they cause. The user can then select technical information relating to probable faults in the system.

  • Patent number: 5415456
    Abstract: A collapsible baby chair apparatus for attachment to an elevated member having a top and bottom surface, such as a tabletop or projecting countertop. The apparatus includes a chair member having a seat portion and a back portion, and a pair of frame members which are operably, pivotally attached to each other in a scissors-like orientation. The seat and back portions may be secured in an opened, seating, position and then releasably foldable to a closed position of reduced profile upon release of a biased locking mechanism. The two frame members each include at least two free ends which are pivotally spread apart and/or closed toward each other by manipulation of the frame members in a scissors-like manner--so as to facilitate positioning of the respective free ends adjacent the top and bottom surfaces of the elevated member.

  • Patent number: 4965820
    Abstract: A cellular telephone apparatus in which several functions such as decoding and encoding data signals, detecting the busy/idle bit and transponding the SAT signal, are carried out by a CMOS data processor (20) which is separate from a CMOS micro-controller (34). The data processor (20) can be operated at a lower clock frequency (1.2 MHz) than the micro-controller (34) which enables current to be saved compared to processing these functions in software using the micro-controller.

  • Patent number: 4441159
    Abstract: A digital adder circuit for binary-coded-decimal operation, comprising a set of multiplexers (11) which are conditioned with a pattern of input bits causing them to form an intermediate result (IR) equal to the sum of the two operands (A0-A3, B0-B3) plus a correction value of six. The intermediate result is adjusted by subtracting the correction value if the intermediate result is less than sixteen. The circuit is also operable in a pure binary mode, or can be made to perform various logical operations.

  • Patent number: 4101685
    Abstract: In a system for flocking a substrate, such as a garment, the improvement comprising a method, apparatus and article for adjustably controlling the moisture content of the flock in the flock tray to any desired moisture level, whereby the flocking machine is not limited to use only in a plant having a humidity controlled atmosphere.

  • Patent number: 4099485
    Abstract: A flocking system including a cabinet supporting a substrate to be flocked and a flock tray, means for raising and lowering the flock tray into and out of contact with the substrate (such as a garment), and means for sealing the moving flock tray to the cabinet to prevent flock from getting into the cabinet to prevent contamination of the mechanics of the internal portion of the cabinet by flock. The flock tray includes a slowly rotating rotor for keeping the flock agitated, a telescoping shaft connecting the rotor to the motor, a flock tray holder for maintaining the seal with the cabinet, and a flock tray cover with one or more flocking masks with various size openings.

  • Patent number: 4098222
    Abstract: A garment holding turret system for a flocking machine including spring biased means for holding excessive portions of a garment in place while the adhesive is being applied and during the flock cycle. The turret has no protuberance at the chest or stomach of the operator to hinder the operator's movements in placing a garment on the turret or during the screen printing operation. The turret can be rotated in one direction for setting up the machine or making adjustments without activating the high voltage and can be rotated in the other direction to activate the high voltage for the flocking operation.

  • Patent number: 4093753
    Abstract: A method and apparatus for applying flock to a substrate, such as a garment, comprising a compact, portable, self-contained flocking machine in which the cabinet and flocking trays are non-metallic and are preferably wood and plastic, respectively, whereby the electric field from an electrode in the flocking tray to the metallic garment holding platen causes the flock to move in a straight, uniform, dense pattern from the flock tray to the garment. In addition, the high voltage electrode in the flock tray is not energized until the flock tray has moved up and made contact with the garment holding platen to prevent flock from coming up out of the tray while the tray is moving up and down and to prevent any risk of shock to the operator. The platen is mounted on a rotatable shaft and diametrically opposed to a similar platen in an uppermost position which is operatively associated with a screen printer. In use, a printed substrate is flocked while an additional substrate is being printed.
