    • A thin loudspeaker is provided that produces a superior frequency response and a diffuse acoustical pattern using magnetic drivers, acoustical plates, or a combination of magnetic drivers and acoustical plates. The invention contains a specially designed crossover network and a novel enclosure design. The novel enclosure includes a septum and cross bracing which enables the invention to realize superior performance in a thin loudspeaker design. The invention encompasses methods for improving the performance of an acoustical plate which include (1) placing acoustical plate motor elements on the plate in a manner that avoids rotational, mirror, and translational symmetry, (2) using acoustical plate motor elements of different shapes and sizes to stimulate the plate, and (3) using an acoustical plate that has an asymmetric shape. All of the embodiments of the invention may be covered with a decorative cover and hung on a wall like a picture or used to form a panel in a home entertainment center.

    • Safety scaffold or platform foldable structures for ladders are disclosed. The scaffold structure embodies an elongated expandable scaffold floor section which is removably connected to two spaced apart upstanding ladders. Male and female floor sections are expanded to the desired length and locked in place by a locking pin. Spaced apart double hook hinges are releasably secured to one rung on each ladder. Wedge mechanisms work in conjunction with the hook hinges engaging the ladder rails to secure the scaffold structure in the horizontal open working position. The platform structure in the form of the letter H is removably connected to two adjacent rungs of a single ladder. The pair of hook arms hook around the upper rung and a pair of bottom arms support the structure on the lower rung. Descending wedge mechanisms engage the ladder rails in supporting the platform structure in the horizontal open working position.

    • A method and apparatus for particle removal in supercritical fluids using a single frequency acoustic wave. A wafer (114) is placed in a process chamber (110) and cleaning gas is introduced through inlet port (116). The cleaning fluid is heated to at least the critical temperature of the cleaning fluid and may also be pressurized. A sonic wave is generated in process chamber (110) by sonic transducer (122) to create alternating bands of gas phase (G) and supercritical phase (SC) of the cleaning fluid. The sonic wave is preferably a traveling wave such that the gas (G) and supercritical (SC) phases move across the surface of wafer (114) removing contaminants from the wafer (114) and trapping them in the acoustic wave. The contaminants are then removed from the system with spent cleaning fluid through outlet port (118).
