A method and system for interfacing internet protocol-enabled emergency calls to a public 9-1-1 system are described. The method can include routing an emergency call originating from internet protocol telephony to a data network via a routing device which may include an identifier. The method can include transferring the routed emergency call to a predetermined public service answering point based on the identifier.

A volumetric representation of a hair simulation model determines collective hair attributes. To determine inter-hair collisions, vertices include average velocities of the adjacent portions of the model. The average velocities determine target velocities. Forces for the model are determined from the target velocity values. To direct hair to a desired pose, vertices include target and current density values representing the density of adjacent portions of the model in the desired pose and current position, respectively. The differences in density values determine pressure forces applied to the model. To determine the illumination of the hair, vertices include density values representing the density of adjacent portions of the model. The density values define a hair surface, and signed distance values relative to the surface are determined for the vertices. Normal vectors are determined from the gradients of the signed distance values at locations corresponding the positions of the hairs.

The invention provides systems and methods for determining discounted rates for insurance on and financial products relating to transgenic traited crops as compared to their traditional, non-traited counterparts. Certain methods of the invention involve generating comparison data contrasting the yields of transgenic traited crops to their traditional non-traited counterparts. The distribution of the differences between the transgenic and traditional yields is measured. The degree of correlation between the transgenic yields and the differences between the transgenic and traditional yields is measured to create a novel method for assessing mitigation of abiotic and biotic stresses by transgenic crops. A probability distribution function is fit to a traditional rate structure, and a distribution for the transgenic crop yield is determined. The discounted premium rate is determined from the probability function, and a discount rate factor is determined.

Methods for rendering an object includes determining diffuse illumination values for object surface points, associating a 3D grid including vertices with the object, mapping object surface points to vertices, determining diffuse illumination values for vertices from the diffuse illumination values for object surface points, low pass filtering diffuse illumination values for the vertices to determine illumination compensation values for the vertices, determining illumination compensation values for the object surface points from the illumination compensation values for the vertices, and determining compensated diffuse illumination values for the object surface points from a weighted combination of the diffuse illumination values and illumination compensation values for the surface points.

Animation controls according to the present invention introduce a predictable level of control for animation without the need for iterating the simulation. Controls include shape controls that permit the effect of the simulation to be overridden for cloth and soft body materials. The effect of shape tacks are to control the local shape of objects such as cloth and soft body materials, the shape may be weighted and time varying. Shape tacking is relative to the reference coordinate system of the object being shaped. Position tacks provide control in absolute space and permit accurate placement of an object to be animated overriding the control of the simulation.

A dynamic cloth simulation technique according to the present invention decomposes the second order differential equations of motion into two first order differential equations which permits separation of position and velocity terms. In another aspect of the present invention tensile stiffness terms are separated from bending and damping terms. The bending and damping terms may be integrated using long time steps to promote simulation stability. Tensile stiffness terms may be calculated in sub-cycle periods shorter than the long time steps used for bending and damping calculations. Use of short sub-cycle steps in simulations of garments having high tensile spring forces permits a stable dynamic simulation with a high degreee of realism.

A high voltage low inductance resistor (120) includes a resistor body (122) having a perimeter and a center. A first terminal (126) is located away from the center of the resistor near the perimeter of the body (122). A serpentine resistance element (130) includes a first end (136). A conductive ring (124) is located near the perimeter and circumscribes the serpentine resistance element (130). The ring (124) is electrically connected to the first terminal (126). The first end (136) is electrically connected to the conductive ring (124). A first resistance segment (138a) of the resistance element (130) begins at the first end (136) and extends in a first direction generally around the perimeter of the body (122). An apex (142a) has an input portion (143) and an output portion (145). The apex (142a) redirects the resistance element in a generally opposite direction, the input portion (143) transitioning into the first resistance segment (138a). A second resistance segment (140a) exits the apex (142a) from the output portion (145) in a second direction generally opposite the direction of the first resistance segment (138a). The second resistance segment (140a) is located adjacent to and spaced apart from the first resistance segment (138a). The pattern of the interconnected first and second resistance segments is arranged to provide a concentric serpentine pattern in a single plane. A second end (148) of the resistance element (130) is located approximately at the center of the resistor element. A second terminal (128) is located at the center of the resistor (120) and is electrically connected to the second end (148) of the serpentine resistance element (130).
摘要:
An ultra-broadband transverse electromagnetic (TEM) exponential antenna in which the radiating or receiving structure comprises first and second elongated conductors have a feed end comprising first and second narrow conductor strips. At an opposite radiating or receiving end, the widths of the first and second conductors expand exponentially in the H-plane, and the spacing between the first and second conductors expands exponentially in the E-plane, thereby providing a double flared, exponentially tapered, transverse electromagnetic horn antenna. Two TEM horn design embodiments are described herein and differ only in the lauching device by which the radiating structure is fed, which converts an input unbalanced transverse electromagnetic wave into a balanced transverse electromagnetic wave. A first preferred embodiment employs a stripline infinite balun as a launching device, while a second embodiment employs a cavity backed waveguide as a launching device. An input coaxial connector introduces an unbalanced transverse electromagnetic wave into the launching device, either the infinite balun or the cavity backed waveguide.
