    摘要: An improved digital signal mixing architecture (100) for applications such as digital mixing consoles (76) is provided. The architecture provides a software configurable mixing system that is expanded up to more than 48 channels. The architecture comprises a master DSP (12) device coupled to a plurality of slave DSP devices (10) on a DMA bus (28). The master DSP (12) is interconnected to each of the slave DSPs (10) in a manner that enables the master DSP (12) to command each of the slave DSPs (10) to write the results of its input signal processing to the internal memory of each of the other slave DSPs (10). The master DSP (12) commands the slave DSPs (10) to transmit processed input signals to each other, so that each processed input signal is stored in the memory of each slave DSP (10). Once each slave DSP (10) has the results of every processed input signal, the master DSP (12) commands any combination of the slave DSPs (10) to mix any of the processed input signals to create a mixed signal that is sent to its outputs for conversion to an analog signal (18b). Mixing combinations are controlled by scripts that are interpreted by software. The digital mixing architecture (100) provides a system that is software configurable, so that mixing console is easily reconfigurable and upgradeable.

    摘要: A static venting system (10) includes a first larger geometrically-shaped member (28) having a plurality of outwardly extending vertical louvers (30) with a top margin and a bottom margin; a second smaller geometrically-shaped member (36) is disposed within the larger member and has a plurality of outwardly extending vertical louvers (39) and a top margin and a bottom margin; a cap member (20) is provided with a first portion for affixing the cap member (20) to the top margin (26) of one of the first or second geometrically-shaped member (28, 36); the base member has a centrally disposed aperture, a portion for affixing the top margin of the other of said geometrically-shaped members thereto and an outwardly extending flange portion for affixing the base member over a vent aperture provided in an external surface; and a means for connecting the base member to the cap member.

    摘要: The subject invention pertains to materials and methods useful for monitoring and management of certain pests well as others biotic and abiotic factors. The invention is particularly well suited for the control of social insect pests, and particularly, termites. The invention concerns methods and apparatuses for monitoring pest activity and presenting a toxicant. The invention is useful as part of an Integrated Pest Management Program and can significantly enhance the efficacy, efficiency and convenience of the management program.
