Abstract: A speaker system, particularly useful as a subwoofer, comprises an enclosure with one acoustic transducer facing to the right and one acoustic transducer facing to the left, which effectively cancels out transducer cone mass induced vibration within the enclosure. The enclosure also has one passive radiator facing up and one passive radiator facing down. The passive radiator facing down effectively couples acoustic energy at very low frequencies into the floor. The passive radiators each have a rather a large area and high mass. The large, high mass, bottom mounted passive radiator will produce large amounts of enclosure vibration, and so to cancel this vibration, the upper passive radiator is of substantially the same mass and size. The resulting system will be vibrationally balanced on all axes while simultaneously effectively coupling low frequency energy onto the floor of the listening room with good efficiency.

Abstract: A stereo loudspeaker system with a right channel and a left channel respectively feeding R and L signals to four speakers (including a right main speaker, a right sub-speaker, a left main speaker and a left sub-speaker) includes a transformer that, depending on the frequency, magnetically couples or isolates the two channels at the right and left sub-speakers. At low frequencies, the transformer isolates the right channel from the left one so that the R signal goes primarily only to the two right speakers, and the L signal goes primarily only to the two left ones. At high frequencies, both the right and left main speakers still receive their respective R and L signals; however, the transformer's magnet coupling conveys a differential R-L signal to the right sub-speaker and a differential L-R signal to the left sub-speaker, thereby producing an expanded acoustic image and realistic ambient field.

Abstract: Systems and methods for providing a user with increased flexibility and control over the appearance and behavior of objects on a user interface are described. Sets of objects can be grouped into themes to provide a user with a distinct overall impression of the interface. These themes can be switched dynamically by switching pointers to drawing procedures or switching data being supplied to these procedures. To buffer applications from the switchable nature of graphical user interfaces according to the present invention, colors and patterns used to implement the interface objects are abstracted from the interface by, for example, pattern look-up tables.

Abstract: Watertight enclosures for digital audio devices include one or more diaphragms for transmitting sound to and/or from the digital device's audio transducers, such as speakers and microphones. To mitigate standing waves and/or prominent natural frequencies, a central portion of the diaphragm is wavy with a relatively low Q (Young's modulus). The central portion is encircled by a peripheral web portion that is relatively thin to provide the central portion with spring support. In some examples, the diaphragm also includes a seal for sealing against the digital device's housing to create a generally closed air chamber between the diaphragm and the audio transducer. The closed air chamber promotes sound transfer between the diaphragm and the audio transducer. The closed air chamber can also reduce crosstalk between a microphone and a proximate speaker. In some examples, a relatively soft diaphragm and a harder enclosure are created using plastic injection overmolding.

Abstract: An audio transducer assembly configured for positioning with respect to a mounting surface, said assembly employing a tweeter in a directionally adjustable body which swivels radially and axially for positioning and directing the tweeter in a desired direction. By keeping the center of rotation at or near the center of the surface of the tweeter, the adjustment of the tweeter does not significantly offset its body in the X or Y direction through its range of motion. Such configuration allows for compensation of the distortion caused by placing the tweeter in the middle of a woofer in a speaker having multiple transducers in a single assembly.

Abstract: A loudspeaker system includes an enclosure having an open end defining a plane, a baffle, a loudspeaker operating in the 4 kHz to 10 kHz range, and a device, preferably a ribbed portion having a plurality of grooves, coupled to the baffle for modifying the spectral profile of the projected sound waves. The baffle includes first and second angled surfaces each oriented at an oblique angle with respect to the plane. The speaker is coupled to the first angled surface and the ribbed portion is coupled to the baffle along the intersection of the first angled surface and the second angled surface. When mounted in a wall or ceiling, the system projects a sound field substantially indistinguishable from that of a loudspeaker located within the listener's listening plane. The baffle can also have acoustic damping material attached thereto, with grooves formed therein, to prevent reflections of 4 kHz to 10 kHz sound.

Abstract: A system for the selectable adjustment of an angle of elevation of groups of PV panels or panel arrays, relative to a roof to which the panels are attached, includes a platform, upon or thru the roof. The platform including horizontally secured rails. Also included are a parallel series of lower couplings, each member of the series provided upon the rails, and having a transverse distance between them sufficient to accommodate a PV panel array. Each of the couplings are provided with integral extensions or tabs, each having an aperture within a portion not in engagement with the platform. The system also includes linear support members secured to undersides of the panel arrays to be selectably elevated, each of the support members substantially co-planar with the rails of the parallel series of lower couplings.

Abstract: An acoustic transducer includes a frame, voice coil movable along a pole, magnetic structure generating magnetic flux in a gap where the voice coil moves, diaphragm attached to the coil, waveguide extension in front of the pole, inner flexible roll seal connecting the waveguide extension to neck area of the diaphragm, and outer seal connecting outer periphery of the diaphragm to the frame. The inner flexible roll seal seals the gap between the voice coil and the pole, isolating the air in front of the diaphragm from the air behind the diaphragm. The inner seal provides damping of unwanted resonances of the diaphragm. Together, the inner seal and the outer seal do not substantially decrease the piston area of the transducer, and do not substantially affect the transducer's movement. In combination, the inner seal and the waveguide extension tend to increase efficiency and decrease audio distortions of the transducer.

Abstract: Systems and methods for providing a user with increased flexibility and control over the appearance and behavior of objects on a user interface are described. Sets of objects can be grouped into themes to provide a user with a distinct overall impression of the interface. These themes can be switched dynamically by switching pointers to drawing procedures or switching data being supplied to these procedures. To buffer applications from the switchable nature of graphical user interfaces according to the present invention, colors and patterns used to implement the interface objects are abstracted from the interface by, for example, pattern look-up tables.

Abstract: A method and apparatus providing visual feedback to a computer user while dragging selected text is described. As its first step, the processing logic creates a text object from the selected text once the computer user has initiated a drag. Simultaneously, the selected text is visually de-emphasized. Secondly, the processing logic snaps the text object to the cursor so that the text object follows the cursor without obscuring text at the insertion point. Finally, when the computer user selects the final insertion point, the selected text is visually zoomed from the source location to the final insertion point.
