摘要： A loudspeaker system (200) includes an overhead sound image generating (e.g., ATMOS™) elevation sound projecting loudspeaker transducer or array (210) for reproducing an elevation signal and a second cancellation loudspeaker or transducer array (250) for generating and projecting a direct signal cancellation. The cancellation speaker or array (250) is driven with a filtered, polarity reversed version of the elevation signal to cancel undesired direct sound (160) from elevation speaker (210) which would otherwise diminish the quality of elevation signal reproduction for a listener L.

摘要： A modular precision rifle assembly 150 and a method for configuring rifle components allowing users to change barrel subassemblies 214 (i.e., for a replacement barrel for use with the same ammunition or a barrel configured for shooting a different ammunition caliber or type) includes three main components including a receiver subassembly 212, a barrel subassembly 214 and a forend subassembly 200. The receiver subassembly 212 includes a receiver housing 300 with a central lumen defining a plurality of substantially cylindrical contiguous cavities aligned along a central axis 300CA. The barrel assembly's bore is automatically forced into axial alignment with central axis 300CA when a user tightens a barrel coupler nut 500 against a barrel extension 400 due to the centering force generated when the extension's centering surface 410 bears against the coupler nut's cooperating centering surface 520.

摘要： A system and method for simultaneously (i) treating a patient's malocclusion by repositioning teeth from an initial tooth arrangement to a final tooth arrangement and (ii) treating Obstructive Sleep Apnea (“OSA”) by forcing the mandible forward comprises a plurality of (e.g., 10-30) sets of individual appliances. The appliances are configured to be placed successively on the patient's upper and lower dental arches and to incrementally reposition the teeth and forcing the jaw forward, during sleep. The system of appliances is preferably configured at the outset of treatment so that the patient may progress through treatment without the need to have the treating professional perform each successive step in the procedure.

摘要： An ocean wave energy absorbing kite system 200 captures an ocean wave's kinetic energy as a force on a submerged, reciprocating panel 202 that drives the panel back and forth in an oscillating motion. The force applied to the panel is transmitted to a power generator 244 through opposed flexible ropes or lines 214, 224 loaded in tension. Potential energy is captured from the wave as a vertical force when a buoyant volume attached to the energy absorbing panel or kite member 202 rises on a passing ocean wave's peak, and transmits the force through flexible ropes or lines in tension to a power generator. Optionally, the shape of the panel is configurable to limit or restrict absorbed wave energy, thereby preventing damage from larger storm-generated waves.

摘要： A multi-element single enclosure loudspeaker system uses all of the available driver elements in a linear array of loudspeaker drivers for purposes of reproducing center channel program material, whether discrete within a multichannel mix (such as Dolby Digital 5.1™) or derived from a 2-channel mixdown via any appropriate means (such as SRS™ or Dolby ProLogic™ algorithms), in a manner that provides optimized intelligibility of dialog, improved overall clarity, natural timbre and dynamics of music or other effects and wide bandwidth for a wide range of seating/viewing locations for (domestic) home theater environments.

摘要： An electro-dynamic loudspeaker transducer's motor structure includes a magnetic circuit having a pole with minimal reluctance that allows the use of larger magnets and thicker front plates, thus generating higher flux density in the voice coil gap. The lower reluctance is achieved by increasing the pole piece's outside diameter at all points outside of the voice coil gap and the area swept out by the voice coil at maximal inward excursion. Increasing the pole's diameter over a substantial amount of the pole's distally projecting length (but not extending into the magnetic gap), provides an increased cross sectional area and a reduced magnetic circuit reluctance.
摘要翻译：电动式扬声器传感器的电动机结构包括具有最小磁阻的磁极的磁路，其允许使用较大的磁体和较厚的前板，从而在音圈间隙中产生较高的磁通密度。较低的磁阻是通过在音圈间隙外部的所有点处增加极片的外径和由音圈在最大向内偏移中扫出的面积来实现的。在极大的远端突出长度（但不延伸到磁隙中）上增加极的直径可提供增加的横截面积和减小的磁路磁阻。

摘要： A loudspeaker system (700 or 800) and method for tuning ported loudspeakers and reducing unwanted acoustic resonances provides reduced port noise, eliminates undesired port resonances and improves the accuracy and fidelity of reproduced sound in a loudspeaker system of relatively high efficiency with an enclosure including an Eigen Tone Filter structure (“ETF”) comprising a pipe or set of pipes 720, 820 placed inside a loudspeaker vent to absorb the “open pipe” acoustic resonance of the vent. The open-pipe resonance is unwanted and interferes with the midrange performance of the loudspeaker, when in use, if not corrected.

摘要： A method for making an improved projectile 360, 460 by defining a discontinuity, groove or trough in a distal ogive section of the projectile to provide an external ballistic. effect uniforming surface feature (e.g., nose ring groove 369, 469) which makes an unsupported gap in the ogive profile that beneficially affects the flow of air over the front half of the ogive. The improved bullet's external surface discontinuity feature (369 or 469) creates effects in the flowfield that dominate any dynamic effects from bullet-to bullet manufacturing inconsistency and resultant differences in dynamic behavior.
