Abstract: The present invention is embodied in a computer-readable program in a computer-readable medium for upgrading a video conference system, the computer-readable program comprising acoustic echo canceling control software having an application programming interface. The acoustic echo canceling control software is implemented on a computer system that operates the video conference system and macros are configured to couple the acoustic echo canceling control software to hardware components of the video conference system and to interface with the application programming interface. The macros are user configurable for providing real time adjustments of echo canceling runtime parameters of the hardware components during a video conference session.

Abstract: The invention provides systems and methods for providing compressed video data from multiple bit streams. The systems and methods apply a two-stage strategy. In the first stage, a conditioning step is performed on a bit stream comprising compressed video data which outputs a conditioned bit stream that is able to receive digital insertions without subsequent decompression of the compressed video data or removal from network packets. The conditioning includes recoding an incoming bit stream such that compressed video data in the bit stream immediately before and after a splice point does not have temporal reliance across the splice point. In the second stage, e.g., at a downstream network device, splicing of compressed video data from a second bit stream into the conditioned bit stream is performed. The splicing takes advantage of the changes made to the conditioned bit stream and may occur at the network packet level.

Abstract: Effects of diffraction of a spectral beam from an edge of the micromirrors are reduced in order to optimize the passband in a wavelength selective switch. The effects of diffraction on the pass band may be reduced by using rotation of the micromirror about both the attenuation axis and the switching axis to achieve the desired level of attenuation. Peak coupling can be attained by dithering the micromirror about a dither axis that is tangent to a contour of constant attenuation using simultaneous rotation about the switching and attenuation axes. A power level of a spectral channel may be attenuated by rotating the channel micromirror with respect to an effective attenuation axis that is non-orthogonal to the dither axis through a combination of rotations about the switching axis and the attenuation axis.

Abstract: According to the embodiments of the Eldridge ENJET—Engine Exhaust Jet Nozzle invention, the method and apparatus include an external plenum, support spool, fan, and nozzle assembly that is sleeved over and mounted at the discharge end of an internal combustion engine exhaust silencer or pipe for the purpose of creating a high volume and high velocity discharge capable of overcoming prevailing wind velocity to such an extent that a cylindrical air discharge pattern 50-100 feet away from the end of the apparatus nozzle provides increased dispersal and dilution of the engine exhaust gas. The invention is especially useful for accelerating the high temperature, low velocity, and toxic internal combustion engine exhaust gas away from human habitation or work areas.

Abstract: A system for manipulating engine exhaust gases away from inhabited areas comprises an air pressurization system coupled in fluid communication to a housing. The housing is adapted to reside adjacent a terminal portion of an exhaust pipe so that pressurized air injected into the housing entrains the exhaust gases and disperses them from the housing.

Abstract: A digital telephone answering device having speakerphone capability allows a recorded message to be played back and heard by the far-end party as well as over the local speakerphone by the near-end party during speakerphone operation as if it were a normal receive signal. Moreover, normal speakerphone conversation is possible during this conversational playback mode allowing the far-end party and/or near-end party to break-in over the played back pre-recorded message as desired and be heard by the other party. Both message and conversation signals are preferably (but not necessarily) at similar levels. Also, the message playback at the near end is preferably (but not necessarily) subject to the same speakerphone digital volume control as that received at the far end.

Abstract: A system and method for predicting yield of integrated circuits includes at least one type of characterization vehicle which incorporates at least one feature which is representative of at least one type of feature to be incorporated in the final integrated circuit product. The characterization vehicle is subjected to at least one of the process operations making up the fabrication cycle to be used in fabricating the integrated circuit product in order to produce a yield model. The yield model embodies a layout as defined by the characterization vehicle and preferably includes features which facilitate the gathering of electrical test data and testing of prototype sections at operating speeds. An extraction engine extracts predetermined layout attributes from a proposed product layout. Operating on the yield model, the extraction engine produces yield predictions as a function of layout attributes and broken down by layers or steps in the fabrication process.

Abstract: A proxy service for simulating real assembly features on a remote device is described. A data stream including reflection data of a real assembly is generated. The reflection data stream may include data associated with proxy types without including the code from the real assembly. A client obtains the reflection data stream. The reflection data stream facilitates the generation of a proxy assembly on the client and allows the client to instantiate features of the real assembly on the client without the code for the real assembly.

Abstract: A remote authoring service is described. Remote page authoring includes receiving a stream of data from a server that includes embedded control attribute data. The embedded control attribute data facilitates the generation of a proxy control and allows a web page designer to make modifications to dynamic elements of the webpage without requiring the executable code for the actual controls. The proxy control may provide preview data of the control to allow the client to perform authoring functions using the proxy control. Modifications made via the proxy control service may then be transmitted to the server where the controls are updated.

Abstract: A method and apparatus for fabricating a MEMS apparatus having a device layer with an optical surface that is supported by a pedestal on a planar support layer that is suspended for movement with respect to a base support by hinge elements disposed in a different plane from the planar support layer. The surface area of the optical surface is maximized with respect to the base support to optimize the fill factor of the optical surface and afford a high passband. The height of the pedestal is selected to position the device layer sufficiently above the base support to afford an unobstructed predetermined angular rotation about each axis. The hinges may be made of thin-film material, fabricated by way of surface micromachining techniques. The hinges are disposed underneath the device layer enabling the optical surface to be maximized so that the entire surface becomes usable (e.g., for optical beam manipulation).

Abstract: A wavelength selective switch architecture for ROADMs for switching the spectral channels of a multi-channel, multi-wavelength optical signal between input and output ports employs a biaxial MEMS port mirror array for optimal coupling efficiency and ITU grid alignment, an anamorphic beam expander for expanding input optical signals to create an elongated beam profile, a diffraction grating for spatially separating the spectral channels, an anamorphic focusing lens system, an array of biaxial elongated channel MEMS micromirrors, a built-in Optical Channel Monitor, and an electronic feedback control system. The bi-axial channel micromirrors are rotatable about one axis to switch spectral channels between ports, and are rotatable about an orthogonal axis to vary the coupling of the spectral channel to an output port and control attenuation of the spectral signal for complete blocking or for a predetermined power level.

Abstract: An in-mold degating device that includes a base having mounting ears for removable attachment to a mold system. The base is removably attached to the die half such that the uppermost surface of the base is flush with the surface of the die half. The insert further includes a body fixed to the base including a pair of opposed surfaces that define predetermined relief angles relative to the base. The body further includes a gate flow passage having an inlet within one of the opposed surfaces and an outlet within the other of the opposed surfaces. The gate flow passage tapers inwardly from the inlet to the outlet. The outlet includes an edge surface that forms an acute angle relative to the gate flow passage. The edge surface defines a shearing edge point that separates the finished molded part from cooled excess material.

Abstract: A nutritional supplement composition containing a mixture of whey protein, amino acids, and other beneficial constituents, and a method for making the composition in a nutritionally compact, easy-to-use form. The composition is made by processing a mixture of whey protein, amino acids, minerals, vitamins, and other selected ingredients at an appropriate temperature and pH. By adjusting the ph of the mixture to within the approximately range of 2.5-5.0, and by processing at an appropriate temperature, it is possible to obtain a gel composition that contains a surprisingly large fraction of whey proteins (and other beneficial constituents) in readily bioavailable form. The composition can be packaged into conveniently-sized containers that are as easy to store or transport as they are easy to use.
