  • Publication number: 20240065649
    Abstract: While performing a tomosynthesis procedure, the breast of a patient is compressed between two compression elements to create an imaging condition. Foam is secured to the rigid substrate of a one of the compression elements. The patient's chest wall is aligned with the leading edge surface of the foam. The inner side of the breast is disposed proximate the lateral edge surface of the foam and the outer side of the breast is disposed proximate the outer lateral edge surface of the foam. A mid-plane is disposed between the inner and outer lateral edge surfaces of the foam. An interface connects a leading edge surface of the foam and compressive surfaces. A portion of the leading edge surface which is aligned with the mid-plane is incompletely compressed.

  • Patent number: 10433041
    Abstract: An outdoor loudspeaker that is weather resistant and includes environmental lighting is described. The lamp is mounted to a cap at the top of the loudspeaker. An audio driver is mounted below the lamp. A system outdoor loudspeakers is also described. The lighting circuitry and the audio circuitry is separate, e.g., separate conduits and wiring in the loudspeaker. The cap can include a light guide, e.g., a lens centrally mounted in the cap or an opaque cover to direct the light downwardly and outwardly. At least part of the loudspeaker can be mounted underground and, in the case of a sub-woofer, the entire chamber can be mounted below ground.

  • Patent number: 10299035
    Abstract: An acoustic lens may improve the directional audio performance of a loudspeaker. Application of the improved directional audio performance to a sound system in a listening area may improve the performance of the audio system. The acoustic lens (or phase plug) may be acoustically opaque and partially fill the cavity formed by the loudspeaker cone. The acoustic lens may provide an improved frequency response and directivity. The improved loudspeaker may provide an improved listening location, for example, in a vehicle, a room or a concert hall.

  • Patent number: 9538268
    Abstract: An improved loudspeaker system includes an asymmetrical array of dissimilar drivers, namely a first driver and a second complementary driver configured in an array and driven in parallel so that the measured on-axis frequency response and the output power (SPL) is improved as compared to a symmetrical array (with similar or matched midrange or mid-bass drivers), while retaining a flat tonal balance. This speaker system and method for voicing was discovered to provide lower distortion, improved frequency response and greater clarity as compared to the prior art or traditional (e.g., MTM) loudspeaker configurations.

  • Patent number: 9426576
    Abstract: An electrodynamic acoustic transducer has a diaphragm and a frame with a pole piece carrying a bulbous waveguide tip which reduces or eliminates high frequency distortions caused by destructive interference within the transducer. The bulbous-tip structure clears the moving parts of the transducer and minimizes diffraction of sound energy, extending forward approximately to the plane defined by the outer periphery of the diaphragm when the diaphragm and voice coil are at rest. The bulbous-tip waveguide member extends radially outward above the central radiating area of the transducer diaphragm or cone so as to obscure the center portion of the diaphragm.

  • Patent number: 9282410
    Abstract: 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.

  • Patent number: 8995697
    Abstract: A forward focused bipolar loudspeaker system includes a front-facing driver array and a rear facing driver array with substantially identical front-facing and rear-facing midrange or mid-bass drivers voiced and driven so that the measured SPL curves of each of the arrays, when measured individually, are tonally balanced. The front array and rear array have substantially identical on-axis and off axis frequency response and the rear array's output power (SPL) is reduced by, preferably, about 6 dB with respect to the output power produced by the front-facing array, while retaining a flat tonal balance for both the front and rear speakers, to produce a sound power ratio of about 2:1 as measured by comparing the front and back SPL levels of the speakers. This bipolar speaker system and method for voicing was discovered to provide greater clarity and improved localization while retaining the spacious envelopment of the bipolar sound field.

  • Patent number: 8724844
    Abstract: The inertial transducer comprises a foot, a modular key, at least one suspension means having at least three contact points, and heat dissipation means comprising multiple heat transfer points. The foot alternatively includes an opening or a cap. The cap may be frangible. Preferably, the foot includes a cylindrical wall that extends within the inertial transducer and the foot's lower surface is coplaner with the lower surface of a housing of the transducer, thereby reducing stack height. The cylindrical wall may or may not be threaded and may accept a shaft from a receiving apparatus used to associate the transducer with a substrate.
