Abstract: Example implementations relate to generating a performance index of an electrical device. An example implementation includes determining an acoustical contour of a soundscape within a computing enclosure for housing the electrical device. A performance response of the electrical device when subjected to the soundscape within the computing enclosure may be determined. Specifically, a soundscape may be generated within a test chamber that replicates the acoustical contour of the soundscape within the computing enclosure. A performance index of the electrical device may be generated upon being subjected to the generated soundscape.

Abstract: In some examples herein relate to a system for testing an axial fan, the system comprising a V-shaped seat to allocate the axial fan, the V-shaped seat comprises a first surface established on a top side of the V-shaped set, a second surface established on the top side of the V-shaped set. An intersection between the first surface and the second surface forms a V-shaped surface of 90 degrees to allocate the axial fan on the V-shaped seat and the V-shaped surface has sticky and resilient properties to fix the axial fan on the V-shaped surface.

Abstract: A vibration attenuation method comprising identifying a hard drive disposed on an electronic device and, based on the identity of the hard drive, attenuating an output of at least one operation of the electronic device.

Abstract: Embodiments of the present invention relate to a system and method for noise suppression. Specifically, embodiments of the present invention include a resonator configured to suppress noise from an electric fan. The resonator may comprise an enclosure having an outer perimeter, a major opening through the enclosure and defining an inner perimeter of the enclosure, a minor opening disposed along the inner perimeter, and a chamber coupled to the minor opening within the enclosure between the inner and outer perimeters.

Abstract: A cooling device having a first fan, a second fan upstream of the first fan, and a flow conditioner element that includes a housing with a first side having a flow-conditioner plate, a second side opposite the first side that defines an opening, and a duct between the first side and the second side, wherein the flow-conditioner plate is attached to a side of the first fan proximal to the second fan and the second side of the housing is attached to a side of the second fan proximal to the first fan. A method for cooling electronic components and a fan assembly are also disclosed.

Abstract: Embodiments of the present invention relate to a computer system. In one embodiment, the computer system comprises a fan and a muffler configured to suppress noise from the fan. The muffler may comprise a plurality of acoustic absorption sheets, wherein the acoustic absorption sheets each have a hole at least generally aligned with a flow area of the fan.

Abstract: An apparatus comprises a housing comprising an air inlet, an air outlet and a divider that divides the housing into first and second air passages. The housing comprises a resonance chamber for each air passage. Each resonance chamber comprises a port, and air waves enter each such resonance chamber through such port and resonate.

Abstract: An elastomeric compressor mount has a hollow convex cylindrical head portion which must be passed upwardly through a substantially smaller diameter circular opening in a support foot portion of the compressor. To facilitate the passage of the mount head portion through the support foot opening a specially designed clamping tool is provided which has an arcuate support portion and a clamping portion that may be pivoted toward and away from a concave side surface of the support portion. With these two tool portions pivoted toward each other they are inserted downwardly through the compressor foot opening, opened, and then clamped exteriorly onto the mount head portion in a manner deforming it to a generally U-shaped configuration as viewed along the axis of the mount.

Abstract: An elastomeric compressor mount has a hollow convex cylindrical head portion which is passed upwardly through a corresponding opening in a support foot portion of the compressor to place an annular portion of the foot in an annular mount groove which is disposed between its head portion and a larger cylindrical base portion of the mount. When a securement bolt is passed axially through a fastening opening in the mount and tightened into an underlying base pan opening, the convex mount head portion is downwardly and radially outwardly deformed to cause the annular foot portion to be resiliently squeezed between the head portion and the underlying base portion of the mount. In a second embodiment of the mount its convex cylindrical head portion is of a solid configuration, and is joined to the mount base portion by an annular flange section coaxially disposed therein.

Abstract: A check valve connectable in a refrigerant line is economically fabricated from only three parts--(1) a copper tubing body connectable in the refrigerant line, (2) a nonmetallic shutoff ball, and (3) an annular valve seat member having a conically tapered seating surface on one of its ends. The seat member is coaxially received within a first end of a longitudinally central portion of the tubing positioned between spun-down opposite end portions thereof, with the seating surface end of the seat member facing the second end of the central tubing portion, and the ball being received in the central tubing portion for axial movement into and out of sealing engagement with the seating surface. Three circumferentially spaced, axially elongated side wall indentations are formed in the central tubing portion.

Abstract: A check valve connectable in a refrigerant line is economically fabricated from only four parts--(1) a copper tubing body connectable in the refrigerant line, (2) a nonmetallic shutoff ball, (3) an annular valve seat member having a diametrically opposite pair of leg portions axially projecting from one end thereof, and (4) an annular stop member also having a diametrically opposite pair of leg portions axially projecting from one end thereof, and further having a diametrically opposite pair of axially extending outer side surface grooves formed therein. The seat and stop members are locked together to form a cage structure by axially press-fitting the valve seat member outer leg ends into the stop member grooves in a manner such that the stop member legs underlie and support the seat member legs, with outer ends of the stop member legs facing a conical seating surface of the seat member in an axially spaced relationship therewith.
