    摘要： A sound enhancement device for a detector includes a cylindrical portion having a tubular body and an interior cavity longitudinally coextensive therewith. The device includes a first elongated portion and at least a second elongated portion with both portions coupled to the cylindrical portion. The first elongated portion includes a first body portion having a first cavity that is coextensive with the first body portion while the at least second elongated portion includes a second body portion having a second cavity that is coextensive with the second body portion. The cylindrical portion and each of the first and at least the second elongated portions comprise a length of a quarter wavelength of a predefined frequency. The sound enhancement device includes radii of curvatures for causing a wavefront emanating from the sound enhancement device to maximize the radiation efficiency of the sound enhancement device.

    摘要： An improved induced draft gas burner assembly (31, 131, 231, 331, 431, 531, 631) for low NOx residential and light commercial gas furnaces (10, 10a) is disclosed. The improved burner includes an upstream assembly coupled to a fuel inlet (55) and an air inlet (43). The air inlet (43) is coupled to a neck (41, 141, 241, 341, 441, 541, 641) extending between the air inlet (43) and the outlet of the neck (41, 141, 241, 341, 441, 541, 641), both of which may be disposed within an optional chamber (42, 142, 242, 342, 442). If used, such a chamber (42, 142, 242, 342, 442) also includes an outlet coupled to a burner (46, 146, 246, 346, 546, 646). In practice, the chamber (42, 142, 242, 342, 442) and neck (41, 141, 241, 341, 441, 541, 641) behave as a Helmholtz resonator that can be tuned to provide an upstream impedance Zup that exceeds the downstream impedance Zdown of the components downstream of the burner assembly (31, 131, 231, 331, 431, 531, 631). The volume of the chamber (42, 142, 242, 342, 442), the length and cross-sectional area and shape or geometry of the neck (41, 141, 241, 341, 441, 541, 641) provide convenient variables for manipulating Zup and stabilizing the flame. Various configurations of the neck (41, 141, 241, 341, 441, 541, 641) may be use to provide a sufficient volume thereby eliminating the need for the chamber (42, 142, 242, 342, 442).

    摘要： Low-loss large diameter optical waveguide attachment devices (i.e., pigtails) and methods and systems of making the same are provided. The optical waveguide attachment devices may include an optical fiber (or other type waveguide) embedded in a larger diameter carrier tube. According to some embodiments, multiple laser beams (from one or more laser) may be utilized to uniformly heat the circumference of the carrier tube. According to some embodiments a maria may be formed in one end of the capillary tube to facilitate optical waveguide insertion and/or provide strain relief.
