摘要： Reduction or cancellation of acoustic noise is achieved by providing an amplified, oppositely phased version of the noise by means of an acousto-fluidic amplifier. The amplified acoustic output noise is delivered through an impedance matching horn in destructively interfering relation with the original noise. Depending on the acoustic noise source and its spatial distribution, the acousto-fluidic amplifier may be a single stage amplifier or multiple stages connected in parallel and/or cascade, with output horns spatially distributed to have the maximum cancellation effect. Sensed noise, prior to fluidic amplification, may be processed in a manner to effect feedback or feedforward control of the amplified acoustic output signals.

摘要： A hot melt adhesive hose assembly comprises a heater circuit wrapped around an external surface portion of the hose assembly, a temperature sensor, and an elongated thermal fuse which is likewise wrapped around an external surface portion of the hose assembly such that successive spiral turns of the thermal fuse are effectively interposed between successive spiral turns of the heater circuit. The thermal fuse may be electrically connected in series with the heater circuit so as to effectively terminate electrical power to the heater circuit as a result of the melting of the thermal fuse, or alternatively, the thermal fuse may be electrically connected in series with the temperature sensor, so as to detect abnormal temperature levels at substantially any location throughout the length of the hose assembly.

摘要： The active/passive absorber for extended vibration and sound radiation control includes principally two layers. The first layer has a low stiffness per unit area which allows motion in the direction perpendicular to its main plane. The second layer is principally a mass layer. These two combined layers have a frequency of resonance close to one of the main structure. The dynamic behavior of the coupled system makes the active/passive absorber a passive absorbe; however, the first layer can be electrically actuated to induce motion in the direction perpendicular to its main plane. This addition property induces and/or changes the motion of the mass layer and therefore improves the dynamic properties of the active/passive absorber system.

摘要： The invention relates to noise or sound control achieved by enclosing the noise source in an active enclosure. Arrays of vibration inputs (for example, shakers, piezoceramics, etc.) are attached to the walls of the active enclosure, or loudspeakers located inside the enclosure can be used to excite the sides of the enclosure. An array of error microphones are located in the radiated acoustic field or PVDF strips are positioned on the wall. A controller senses the levels of sound observed at the error microphones or PVDF film and adjusts the oscillating inputs (in terms of frequency content, phase and magnitude) to the active vibration inputs in order to minimize the radiated sound.

摘要： The active/passive absorber for extended vibration and sound radiation control includes principally two layers. The first layer has a low stiffness per unit area which allows motion in the direction perpendicular to its main plane. The second layer is principally a mass layer. These two combined layers have a frequency of resonance close to one of the main structure. The dynamic behavior of the coupled system makes the active/passive absorber a passive absorber; however, the first layer can be electrically actuated to induce motion in the direction perpendicular to its main plane. This addition property induces and/or changes the motion of the mass layer and therefore improves the dynamic properties of the active/passive absorber system. The active/passive absorber can have multiple mass layers and multiple elastic layers stacked one on top of the other. In addition, the mass layers can be continuous or discretized, and have varying thicknesses and shapes for sections and/or segments in the mass layer.
