  • Patent number: 6168358
    Abstract: A hybrid tool serves as a form on which constituent materials are applied for bonding or curing into a part in a desired configuration. It also serves as a holder for the bonded or cured materials in the originally applied position during subsequent machining. The hybrid tool is made by fabricating a face sheet of composite material having a facing surface configured to the reverse of a desired shape of one surface of a part to be made on the tool. The actual part will be laid up on the facing surface, cured while on the tool, and even trimmed before release. Base structure of the tool holds the facing surface of the face sheet in the desired shape, and includes ground-engaging pads that define an “A” datum plane. The tool aligns a reference plane of the face sheet parallel to the datum plane. A substantially continuous groove in the face sheet, used for trimming the part, opens in the facing surface.

  • Patent number: 6169609
    Abstract: A color mapping scheme is provided which enables a K-only black point while minimizing interpolator image artifacts. Specifically, a system and method of reducing image artifacts for a color imaging device include implementing a color map so that no C, M or Y color value that is used in defining the black point is produced, except at the black point. The system and method further include implementing a halftone ramp so that: (i) a halftone pattern is selected to provide no rendering for any C, M or Y color value that is used in defining the black point, and (ii) a halftone pattern is selected to provide a full rendering for any K color value that is used in defining the black point. The color map is also implemented so that no C, M or Y color value that is used in defining the black point is obtained as a result of interpolation, except for at the black point.

  • Patent number: 6162266
    Abstract: An apparatus and a process for cooling a feed injector of a gasification reactor that produces synthesis gas is described. Cooling fluid is injected into a channel in the feed injector adapted for circulating the fluid. The injection pressure is maintained near or above the gasification reactor pressure. The fluid is withdrawn from the channel through an outlet at an outlet pressure between about 515 KPa above to about 1030 KPa below the gasification reactor pressure. The fluid is cooled, degassed, and injected back into the channel in the feed injector. The pressure on the cooling system is variable and tracks the gasification reactor pressure.

  • Patent number: 6154673
    Abstract: This invention relates to an external defibrillator whose language of operation can be easily changed when the defibrillator is deployed for use. Defibrillators include, manual defibrillators, automatic or semi-automatic external defibrillators ("AEDs") and defibrillator trainers. In one embodiment, the invention provides a way to change the language in which the defibrillator delivers instructions to a user. Defibrillators of this invention would contain multiple languages in their memory. During the set-up of the defibrillator some or all of the languages could be designated as a language in which a prompt will be offered. Additionally, during set-up, one language will be designated as the default language. Once the defibrillator is deployed for use in an emergency, the operator will indicate a language preference for the defibrillator operating instructions.

  • Patent number: 6141174
    Abstract: A method of multi-channel magnetic tape recording and reading that compensates for track pitch changes. The method utilizes a closed loop servo system to adjust lateral and azimuth position of the recording head assembly. Servo information is written at a slight azimuth angle, adjacent the outer most tracks of a band of tracks. The recording angle being based on a dimensional stability coefficient of the tape. After data is written at the initial angle, the azimuth angle of the head is rotated through a predetermined range of angle during read-only to align the outermost read gaps with the servo tracks. By doing so, signal strength is maximized across all tracks, even if track pitch changes.

  • Patent number: 6134465
    Abstract: In an MR system employing a phased array surface coil, a method is provided for reducing artifacts in an MR image acquired from a region of an object lying within a specified field of view, wherein the field of view has a dimension extending between first and second boundary limits. The method includes the step of positioning the phased array surface coil, which comprises a linear array of coil elements, in selected spatial relationship with the object region. The method further comprises selecting a particular coil element for use in acquiring MR data only if the coil element lies at least partially in a range which extends along the phased array and has a length equal to the field of view dimension, the range lying between positions respectively corresponding to the first and second boundary limits.

  • Patent number: 6129768
    Abstract: According to a method and apparatus for balancing a container using a closed system fluid balance ring for high rotational speed washing machines, the transfer of fluid is pulsed, allowing for a variable overall mass transfer rate while computation of the imbalance continues. Mass transfer continues until any significant imbalance is eliminated. The quasi-constant nature of this method allows for the resulting imbalance tolerances to be significantly lower. As the imbalance decreases, the mass transfer rate is varied accordingly.
