    Abstract: A radiation therapy system comprises a magnetic resonance imaging (MRI) system combined with an irradiation system, which can include one or more linear accelerators (linacs) that can emit respective radiation beams suitable for radiation therapy. The MRI system includes a split magnet system, comprising first and second main magnets separated by gap. A gantry is positioned in the gap between the main MRI magnets and supports the linac(s) of the irradiation system. The gantry is rotatable independently of the MRI system and can angularly reposition the linac(s). Shielding can also be provided in the form of magnetic and/or RF shielding. Magnetic shielding can be provided for shielding the linac(s) from the magnetic field generated by the MM magnets. RF shielding can be provided for shielding the MRI system from RF radiation from the linac.

  • Patent number: 11043199
    Abstract: A sparse acoustic absorber includes a periodic array of spaced apart unit cells, generally having a lateral fill factor less than 0.5. Each unit cell includes a pair of joined, and inverted, Helmholtz resonators, having neck portions that point in opposite directions. This structure enables ambient fluid, such as air, to pass through the absorber. The absorber predominantly absorbs acoustic waves having a resonant frequency when such waves are incident on the absorber in one direction, and predominantly reflect such waves when they are incident on the absorber in the opposite direction. Dual-function sound suppression systems incorporate such an absorber into a porous substrate, such as a wire mesh, that enables fluid to pass and alternatively absorbs or reflects sound.

  • Patent number: 10269338
    Abstract: A hard panel of wall and floor structures for reducing floor impact sound according to example embodiments includes patterned layer having different density and elastic modulus form a base layer. A transmission path of an acoustic wave may be changed in a lateral direction by passing the patterned layer and the sound energy is dissipated by the refection, refraction, and cancellation of the acoustic wave. Thus, a noise is reduced. The hard panel of the wall and floor structures according to example embodiments is effectively reduces the light and heavy impact sounds. In addition, the hard panel is formed by at least one patterned layer to refract and reflect the acoustic wave such that the floor noise may be effectively dissipated. The hard panel is further includes the sound absorbing material to absorb the noise passing through the hard panel such that the floor noise can be effectively reduced.

  • Patent number: 7467687
    Abstract: An enclosure for apparatus that, during operation, generates heat and/or sound energy comprises at least one wall defining at least a portion of the enclosure hollow interior. The wall comprises in sequence outwardly from the enclosure hollow interior an inner panel, an outer panel, a support frame between the inner and outer panels to hold the inner and outer panels spaced apart, and a vibrator isolator between the support frame and the panels. Panels or panel segments of the wall primarily are made of non-metallic composites to provide a structurally strong, lightweight enclosure that includes enhanced acoustic characteristics and reduced heat transfer through enclosure walls, along with fire protection and in-plane shear loading capabilities.

  • Patent number: 7380636
    Abstract: The noise reducing equipment of the present invention is used in combination with a vertically oriented sound barrier wall to reduce the level of noise from a source of sound such as traffic generated on one side of the sound barrier wall and comprises an assembly composed of a predetermined number of interconnected resonant chambers mounted in tandem to said sound barrier wall in a relationship such that the assembly extends from said sound barrier wall on the side thereof opposite the source of sound with the resonant chamber closest to the sound barrier wall having a volumetric area larger than the volumetric area possessed by each of the other resonant chambers and an additional sound barrier section extending from the most distant resonant chamber relative to the location of the sound barrier wall. In addition, at least one external surface of the assembly should be coated with a photo-catalyst comprising titanium dioxide.

  • Patent number: 7322440
    Abstract: An ultra light, noise reducing composite (1) comprises an acoustically transparent, light weight film (6) between an underlay layer (5) and an air flow resistance layer (4). This composite allows to easily tune the acoustic properties by balancing the absorption and sound transmission behaviour of the composite (1). This air flow resistance layer (4) has an air flow resistance of between 500 Ns/m3 and 10,000 Ns/m3 and an area mass between 200 g/m2 and 3,000 g/m2. The underlay layer (5) has a stiffness value in the range between 100 Pa and 100,000 Pa. The light weight film (6) may consist of a synthetic foil and preferably has a thickness of 0.01 mm.

  • Patent number: 7314212
    Abstract: A deformation and weather resistant, noise attenuating fencing assembly comprises a series of hollow posts, each post formed of a fiberglass reinforced resin, having spaced apart load bearing walls defining an exterior surface, an interior surface, a first open end and a second open end. The structure-reinforcing cap is inserted within a first open end of each of the posts and frictionally engages the interior surface of the post to substantially prevent movement of the exterior surface thereof when various types of appurtenant structures are mounted thereon, which would otherwise cause deformation and possible structural failure of the post walls. First and second clips are inserted into the first and second open ends of the post, respectively, to provide an easy mechanism to properly space and secure the posts together.

  • Patent number: 7246681
    Abstract: A radio frequency (“RF”) shielded and acoustically isolated enclosure that efficiently employs multiple layers of sound insulation and absorbs airborne noise and the noise provided by magnetic resonance imaging (“MRI”) equipment through the supports of such equipment. The RF enclosure uses multiple layers and types of insulating materials positioned to maximize the noise absorption of the RF enclosure. This reduces the cost and space required by the enclosure. In one embodiment the enclosure includes a ceiling, a floor and a plurality of walls. The ceiling and walls include one or more multiple layers of different insulating materials that either abut each other or form air gaps. In one embodiment the floor includes a heavy metal plate on which the MRI equipment sits. The plate elastically couples to a conductive shield. The elastic coupling attenuates certain frequencies above the natural frequency of the metal sheet.
