Abstract: A method for color error diffusion using semi-vector quantization is proposed that simplifies error diffusion calculations. When three color separations are used, the two separations with the most visually perceptive color output are compared with one another to determine their output colors, while the third, least visually perceptive separation, is treated separately.  A correction term may be applied to the third separation based on the color output of the first two separations to insure uniformity of ink coverage. This method yields results close to vector quantization and also minimizes fluctuation in the two most visually perceptive output colors. Of course, this method may be used with more than three color separations. For example, when four color separations are used, the least visually perceptive color is processed differently than the three other color separations.

Granted: 2003-10-21
Abstract: An arc jet CVD system includes a plurality of plasma jet distribution heads. The distribution heads are preferably linearly arranged, preferably angled relative to a line normal to the substrate surface on which a diamond film is being coated, and preferably spaced relatively apart with respect to a defined profile width. In addition, the plasma jets are preferably configured in accord with a defined parameter which is a function the reagent gas flow and viscosity, the distance between the distribution heads and the substrate, and the area on the substrate exposed to the gas from a distribution head.      Configuring the plasma in accordance with the defined parameter-ensures an acceptable minimum level of efficiency with respect to hydrogen reagent use, and further provides a relatively uniform diamond film coating on a substrate. It is also preferable that the plurality of jets and substrate are preferably moved relative to one another during diamond film deposition for increased uniformity. The combination of the relative arrangement of the distribution heads, the configuration with respect to the defined parameter, the angling of the distribution heads, and the relative movement between the distribution heads and the substrate provide an efficiently operable system for manufacturing substantially uniform thickness diamond film.

Abstract: A serpentine belt drive system (18) for an automotive vehicle comprising a drive assembly including an internal combustion engine (10) having an output shaft (14) with a driving pulley (16) thereon rotable about a driving pulley axis. A sequence of driven assemblies each has a driven pulley rotable about an axis parallel with the driving pulley axis and a serpentine belt (20) mounted in cooperating relation with the driving pulley (16) and with the driven pulleys in a sequence which corresponds with the sequence of the driven assemblies when related to the direction of movement of the belt to cause said driven pulleys to rotate in response to the rotation of the driving pulley. The sequence of driven assemblies includes an alternator assembly (26) including an alternator shaft (36) mounted for rotation about a shaft axis. A hub strucure (52) is fixedly carried by the alternator shaft (36) for rotation therewith about the shaft axis. A  spring and one-way clutch mechanism couples the alternator pulley (26) with the hub structure (52). The spring and one-way clutch mechanism (72) comprises a resilient spring member (74) separately formed from and connected in series with a one-way clutch member (76). The resilient spring member (74) is constructed and arranged to transmit the driven rotational movements of the alternator pulley (26) by the serpentine belt (20) to the hub structure (52) such that the alternator shaft (36) is rotated in the same direction as the alternator pulley (26) while being capable of instantaneous relative resilient movements in opposite directions with respect to the alternator pulley during the driven rotational movement thereof. The one-way clutch member (76) is constructed and arranged to allow the hub structure and hence the alternator shaft to rotate at a speed in excess of the rotational speed of the alternator pulley when the speed of the engine output shaft is decelerated to an extend sufficient to establish the torque between the alternator pulley (26) and the hub structure (52) at the predetermined negative level.

Granted: 2007-04-03
Abstract: A system providing access to web objects that matches predicted demand for web objects to available capacity on web servers. The system implements methods to dynamically shape both demand and capacity based on certain criteria. The system provides methods to dynamically shape demand for an object based on criteria such as arrival time, incoming geography, and costs requirements. In particular, the present invention characterizes future demand for an object based on aggregation and forecasting of past demand for such object. The system effectively permits control and customization of capacity across one or more media servers based on characteristics associated with the demand across one or more of them, and particularly, based on the dominating geographical traits of past demand. Moreover, the system dynamically shapes capacity by: (a) controlling the number of replicas associated with an object; and, (b) controlling the placement of these replicas across servers in a distributed network. In particular, the system drives capacity shaping measures over a particular object based on its predicted demand. Consequently, the number and location of replicas associated with an object is made to be variable over time and driven by predicted demand for a web object.

Abstract: The present invention relates to an improved trileaflet mechanical heart valve (100) and an improved leaflet (110) for use with such valve. The valve (100) and leaflet (110) of the present invention provide improved flow characteristics, minimize blood clotting behind the leaflets, and provide more natural opening and closing times. The valve includes a valve housing (105) which contains pivot/hinge mechanism (130, 200, and 300) for allowing rotation of and retention of the leaflets (110). The valve housing (105) also includes windows or openings (125) which allows for complete washing of the pivot/hinge mechanism (130, 200, and 300) as well as the leaflets (110). The novel leaflets (110) are air-foil-like having a complex S-shaped curvature on their outer surface. This novel geometry, when combined with the location of the leaflet's pivot axis, causes a tendency for the leaflet (110) to rotate towards the closed position. Thus, the leaflet (110) begins to close much earlier than a conventional leaflet and is substantially closed before the flow reverses, similar to the function of a natural valve.

Title: Resource sharing with sliding constraints
Inventor: GRAY THOMAS
IPC: G06F9/46
Filed: 2001-08-20
Granted: 2008-05-06
Abstract: The resource sharing system according to the present invention dynamically adjusts the priorities at which requests from applications in different request classes (or classes of service) for a shared resource, are processed. The dynamic priority of a request class is based in part on the average resource allocation to requests in this request class, and in part on settings for the minimum and maximum allocations to the request class. The average resource allocation is the proportion of time the shared resource has been assigned to requests of this class relative to other classes. The dynamic adjustment of priorities uses "sliding constraints" whereby the priorities are caused to "slide" with the average resource allocation, and the priority imposes a constraint on when the requests of a resource class can be satisfied: namely, when there are no other requests from higher-priority request classes waiting for the resource.
