摘要： A dry sprinkler installation and sealing device for a cold environment is disclosed. The dry sprinkler installation includes a supply conduit having a first end adapted to communicate with a fire retardant fluid source and a second end supporting a sprinkler head. The supply conduit is dimensioned to extend through an opening in a wall of a cold environment, e.g., a freezer ceiling. A flexible sealing device is positioned about the supply conduit adjacent an exterior surface of the cold environment. A first end of the sealing device is secured about the supply conduit and a second end of the sealing device is secured to an exterior surface of the cold environment. The flexible sealing device allows for radial and axial adjustments to the supply conduit and sprinkler head without comprising the integrity of the sealing device.

摘要： A system and method for achieving extended low-frequency response and increased low-frequency sound pressure output capability in a loudspeaker system is provided. The system and method comprise mounting a low-frequency driver in a ported box, tuning the ported box to a sufficiently low frequency so as to result in a frequency response that can be modeled substantially as a second-order response, and equalizing the response of said driver-box combination with a second-order biquadratic filter function to achieve the desired frequency response characteristic.

摘要： A system and method for optimizing dispersion in an optical transmission line is provided. The system and method comprise measuring the amplitude of a d.c. voltage component of a synchronously demodulated data signal of at least one wavelength channel by an in-phase carrier at the baud frequency of the wavelength channel. In an alternative embodiment, the system and method comprise measuring the IF amplitude of the resulting a.c. signal of a data signal of the at least one wavelength channel comprising a received RZ signal mixed with a local oscillator, whose frequency differs from the wavelength channel baud by a relatively small amount, somewhere on the order of about 100 kHz.
