A halftone screen generator, a halftone screen and a method for making the halftone screen are described. The halftone screen has a screen angle and rulings that define the theoretical centers of gravity of the halftone dots. The actual centers of gravity of the halftone dots are displaced from the theoretical centers of gravity by the length and angle of random phase vectors. In one example, the positional displacement of the centers of gravity of the dots is dot size dependent in an inverse relationship. The shift in dot centers of gravity away from the theoretical centers of gravity defined by the halftone screen effectively breaks up screen "patterning" and avoids objectionable halftone "graininess".

A mobile, real-time, closed-loop system and method for delivering an aerosol insecticide spray to a treatment area during a treatment period of time employs a prime mover having a spray nozzle through which an air volume is produced in order to entrain insecticide as particles in an airstream passing out of the nozzle. A particle size detector, weather centers and an electronic controller are used to regulate the amount of insecticide and particle size dependent upon speed of the prime mover and weather conditions at the treatment area.

An arrangement (124) and method (310-360) for Transmission Control Protocol (TCP) flow control in a communication system, by: determining delay in a transmit buffer of the system; and modifying TCP window size dependent on the determined delay.

The present invention provides a method and apparatus for sampling data flows in a data network in order to estimate a total data volume in the network. Sampling the data flows In the data network reduces the network resources that must be expended by the network to support the associated activity. The present Invention enables the service provider of the data network to control sampled volumes in relation to the desired accuracy. The control can be either static or can be dynamic for cases in which the data volumes are changing as a function of time.

A customer is presented with a product ordering interface for a size dependent product such as a window covering. The customer is presented with ordering options. Once the customer has selected the desired product, the user is presented with a measurement confirmation interface. The customer is directed to enter at least one first measurement and one second measurement. The measurement(s) are entered into the customer ordering interface. From these measurements the system calculates a theoretical dimension for a product feature. The customer also measures the actual dimension of the product feature. The ordering system compares the calculated dimension to the customer measured dimension. If the calculated dimension matches the customer measured dimension, the measurement is confirmed.

A security marker material comprising emissive particles and the emissive particles can be grouped into at least two groups with different size distributions and the size distributions satisfy the formula:

[(x−z)²/(S_x^s+S_z²)]^1/2>1

where x and z are the volume-weighted mean equivalent-spherical diameters of the two particle distributions and S_x and S_z are the standard deviations of the same two distributions. The security marker material is part of a security system and authentication is based on criteria which include responses related to marker size and size distribution. This invention provides a less expensive method of generating a more complex, difficult-to-replicate security code.

A prosthetic heart valve may include a stent body with a plurality of cells arranged in circumferential rows and a cuff attached to the stent. A leaflet attachment panel may be attached to and span a portion of one of the cells. A prosthetic valve element, such as a leaflet having a belly, may be mounted to the leaflet attachment panel.

A method for operating an optical projection system including projection optics is disclosed. The projection optics project an image of the object on the substrate at an image distance from the projection optics. The image has a size dependent on the size of the object and the ratio of the image distance to the optical distance of the object from the projection optics. The image distance can change with changes in the condition of the projection optics such as changes in the temperature of elements of the projection optics. The image distance is monitored. If the image distance changes, the substrate is moved to the new image distance and the optical distance of the object is correspondingly changed such that the ratio of the image distance to the object distance stays the same.

A reception-process manager of a call server writes, in a transfer-voice-data storage, voice data contained in a voice packet received from the transmitter terminal which has acquired the talk right. A transmission-process manager of the call server determines the next transmission interval of a voice packet for each receiver terminal on the basis of determination information received from the each receiver terminal. The transmission-process manager reads out the voice data in a size dependent on the determined transmission interval from the transfer-voice-data storage, generates voice packet containing the voice data for the each receiver terminal, and transmits the voice packet to the each receiver terminal. Thus, the voice-packet transmission interval can be changed for each receiver terminal without stopping voice-packet transmission.

A system and method for determining transistor model parameters that account for layout-dependent features in the transistor being modeled, and also in neighboring devices in the same integrated circuit. A computer-readable expression of the integrated circuit layout is retrieved, and active and gate layers in that expression extracted. For a transistor being modeled, its active regions are analyzed to determine whether these regions have a complex shape. Model parameters are derived based on volume effects of the complex shaped active regions. Neighboring active regions that affect parameters of the transistor being modeled are also identified and their effective depth determined. Strain effects due to complex shaped active regions and neighboring elements are thus included in the transistor model.
