摘要： A biplane line array speaker includes a line array of tweeters mounted substantially directly in front of a line array of woofers. The tweeter line array is arcuately shaped to provide controlled vertical dispersion above and below the boundaries of the speaker cabinet. The woofers are displaced from the tweeters in stepped manner. The speaker cabinet is a rectangular box, allowing efficient wall mounting in single or multiple unit columns. IN multiple unit columns, the individual units acoustically couple to each other.

摘要： A planar electro-acoustic transducer has an adjustable back cap option that provides a dipole/monopole radiation that has different roll-off characteristics. The planar electro-acoustic transducer includes a diaphragm and a plurality of front and rear magnetic bars. Each magnetic bar has a side facing the diaphragm and disposed adjacent thereto. The thickness of each rear magnetic bar is larger than the thickness of each front magnetic bar. The thickness of each front magnetic bar is less than a quarter-wavelength of a cavity resonance at 10 kilohertz. The planar electro-acoustic transducer also includes a non-magnetic acoustically transparent metallic mesh that is disposed coplanarly with the sides of the front and rear magnetic bars that face the diaphragm.

摘要： The present invention relates to a class of luminescent and conductive polymer compositions having chromophores, and particularly solid films of these compositions exhibiting increased luminescent lifetimes, quantum yields and amplified emissions. These desirable properties can be provided through polymers having rigid groups designed to prevent polymer reorganization, aggregation or π-stacking upon solidification. These polymers can also display an unusually high stability with respect to solvent and heat exposures. The invention also relates to a sensor and a method for sensing an analyte through the luminescent and conductive properties of these polymers. Analytes can be sensed by activation of a chromophore at a polymer surface. Analytes include aromatics, phosphate ester groups and in particular explosives and chemical warfare agents in a gaseous state. The present invention also relates to devices and methods for amplifying emissions by incorporating a polymer having an energy migration pathway and/or providing the polymer as a block co-polymer or as a multi-layer.

摘要： An elliptically shaped speaker has a driver assembly which may include a woofer driver and a tweeter driver. The speaker has a uniquely designed bridge member. The bridge member acts both as a structural element and waveguide for the tweeter. It has a specific elongated, elliptical shape that allows the speaker to be inserted into a corresponding cut-out opening in a wall, ceiling or any other structural panel, then rotated behind the panel and re-inserted from behind into the opening, thereby providing a secure seal and exact positioning within the panel. The resulting system allows for a low frequency speaker to be installed behind the panel with a noticeably smaller opening than the total size of the speaker.

摘要： A method for forming a photovoltaic cell which includes forming a nanostructured layer in a semiconductor material having a plurality of pores opening onto a surface, the plurality of pores having a depth greater than about 1 micron and a diameter between about 5 nanometers and about 1,200 nanometers, and disposing an organic charge-transfer material in the pores of the nanostructured layer. A first electrode is attached to the semiconductor material, and a second electrode is attached to the organic charge-transfer material. The semiconductor material has a thickness between about 5 microns and about 700 microns. Desirably, the nanostructured layer has a porosity of less than the porosity corresponding to the percolation threshold, and the organic charge-transfer material extends at least about 100 nm from the surface of the nanostructured layer. The organic charge-transfer material may partially cover the sides of the pores of the nanostructured layer thereby providing a generally cylindrical cavity therein.

摘要： The invention is a loudspeaker for use in home theater or multi-channel sound systems that includes an enclosure, a wideband transducer, a sound absorbing pad and an aiming knob. The wideband transducer is rotatably mounted in the enclosure so that the wideband transducer can be rotated around its vertical axis and an aiming knob mechanically coupled to the wideband transducer. The wideband transducer has a front side and a rear side open so that said wideband transducer operates as a dipole transducer. The aiming knob controls the rotation angle of the dipole transducer. The loudspeaker uses the dipole transducer to create either a diffuse field or direct radiating surround sound.

摘要： A planar magnetic driver includes covering plates that are maintained under tension to form a buckled or curved surface, thereby providing for a larger magnetic gap, and allowing for a larger excursion of the diaphragm and extended lower frequency response. Another aspect of the driver includes a corrugated region along the periphery of the diaphragm, which provides increased internal dampening.
