Abstract: A method includes generating at least one matrix representing a two-port, generating gain, noise, and stability functions of a system comprising the two-port, a generator connected to one port of the two-port, the generator having a generator reflectance, and a load connected to the other port of the two-port, the load having a load reflectance, and optimizing the gain, noise, and stability functions. The two-port comprises a non-reactive multi-port modeled by an orthogonal matrix, and at least one amplifier connected to the non-reactive multi-port. The orthogonal matrix is parameterized using an exponential map of skew-symmetric matrices having components restricted to an interval from ?? to ?. The gain, noise, and stability functions are generated using the generated matrix, the generator reflectance, and the load reflectance, The gain, noise, and stability functions are parameterized by the skew-symmetric matrices.

The laminar fluid flow structure may include a solid core member with a plurality of discrete bores therethrough or a plurality of baffles extending longitudinal through a hollow core member. The laminar flow reduces noise, structural failure, erosion, cavitation, and premature wearing of valve seals and seats.

Abstract: A technique for imparting latent elasticity to components of an absorbent article is provided. More specifically, a latent elastic film that contains a crosslinkable semi-crystalline polyolefin is initially incorporated into an absorbent article. The film is not highly elastic prior to crosslinking and is thus dimensionally stable. Consequently, the film need not be maintained in a mechanically stretched condition during attachment to other components of the absorbent article, which provides for greater freedom in the location and manner in which the components are attached together. Once incorporated into the absorbent article, the semi-crystalline polyolefin is crosslinked to form a three-dimensional network having elastic memory. The film may also be heat activated, either through crosslinking or an additional step, to cause the film to shrink and further improve its stretch characteristics.

Abstract: A pump gear includes a pump gear body having involute teeth that each have an involute surface that extends between a tooth tip and a tooth base. The involute surface includes at least reference points A-D, with reference point A near the base, reference point D near the tip, reference point B between reference points A and D, and reference point C between reference points B and D. The reference points A-D have associated respective roll angles, ?A-D, between a corresponding first line that is perpendicular to the involute surface at the given reference point A-D, and a second line that is tangent at a reference point that lies on a terminal end of the involute surface at the tooth base to a reference base circle having a center origin at the center axis.

Abstract: A remote administration system is described herein that provides varying permissions to invoke administrative commands to multiple users. An application host provisions users of different organizations and defines one or more commands that the users can invoke remotely. The system associates the commands with users and/or groups to specify the users and/or groups that are authorized to execute the commands. When the remote administration system receives a remote request to perform a command, the system determines a user associated with the command and whether the user is authorized to execute the command. The system also creates an execution context for each connected user that defines the roles and access privileges associated with the user and that isolates the user from other users. Thus, the remote administration system provides remote administration of hosted applications in a way that is easy for administrators of the hosted service to manage.

Abstract: A system includes a first circulator, a second circulator connected to the first circulator and a load, a third circulator connected to the second circulator, and a filter connected between the first and third circulators. The filter modifies the phase and amplitude of a first signal from the first circulator to produce a modified first signal. The modified first signal amplitude may be equal to the amplitude of a second signal from the second circulator. The phase of the modified first signal is about 180 degrees out of phase with the second signal phase. The third circulator circulates the modified first signal towards the second circulator. The first signal comprises a coupled signal from the first circulator. The second signal comprises a signal reflected from the load and a coupled signal from the second circulator. The filter may be a passive network having lumped, distributed, and resistive elements.

Plastic-rich mixtures are subjected to the process, and one or more recycled plastic materials are collected as outputs of the sequence of processes.

Abstract: Universal master boards and methods of making flush door skins and doors from the universal master boards are disclosed. The universal master boards each have an expansive surface with a graphic design of at least first depressions and second depressions in at least first and second surface regions, respectively. The first depressions simulate a first wood grain pattern, and the second depressions simulate a second wood grain pattern aligned in a different direction than the simulated first wood grain pattern. The universal master boards may be cut and demarcated selectively to establish different assortments of simulated wood patterns and different ornamental features, such as stiles and rails.

Abstract: An optical element is disclosed, for receiving relatively narrow light from a planar light-emitting diode (LED) source, and for redistributing the light into a relatively wide range of output angles that span a full 360 degrees. The element may be used to retrofit existing fixtures that were originally designed for incandescent bulbs with LED-based light sources that have similar emission profiles. The element is small enough so that it may be packaged along with an LED module and its control electronics in the volume envelope of an incandescent light bulb. An exemplary element is a single, transparent, rotationally-symmetric lens that has a batwing shape in cross-section, extending angularly away from a longitudinal axis. The lens also includes a variety of curved, straight, specular and optionally diffuse portions on its longitudinal and transverse faces, all of which cause a variety of internal and external reflections, refractions, and optionally scattering.

Abstract: A method and system for synchronization of detection loops in a multilane environment. A plurality of loop sensors are arranged in a plurality of lanes such that loop sensors in adjacent lanes are mutually contiguous. A simultaneous synchronization signal is sent to each of the plurality of loop detector controllers, where each loop detector controller is in communication with a loop sensor. The signal causes a scheduling of sampling periods for each loop sensor, such that the sampling period of each loop sensor does not overlap with that of a contiguous loop in an adjacent lane.

Abstract: An illuminator is disclosed, in which an LED module emits short-wavelength light toward a phosphor module, which absorbs it and emits wavelength-conditioned light. The emission is generally longitudinal, with a generally Lambertian distribution about the longitudinal direction. The phosphor module includes a transparent layer, closest to the LED module, and a phosphor layer directly adjacent to the transparent layer. Both layers are oriented generally perpendicular to the longitudinal direction. The illuminator includes a reflector, circumferentially surrounding the emission plane in the LED module and extending longitudinally between the emission plane and the transparent layer. Virtually all the light emitted from the LED module either enters the phosphor module directly, or enters after a reflection off the reflector.

The filters each define a subsystem port and operate within the specific frequency range. Each subsystem port has a port index determined by the direction of circulation of the circulator within the subsystem. Each subsystem port has a specific port index that is connected to a common port having the specific port index. At least one of the circulator ports may be terminated to a matched load. Each subsystem circulator may comprise at least three circulator ports, with a filter connected to each of the circulator ports.
