Abstract: Systems, methods, and computer media for adjusting acoustics in real time are provided herein. An acoustic adjustment system can include a processor, a memory, a voxelizer, and a pathing analyzer. The voxelizer can be configured to generate a voxel-based representation of a three-dimensional (3D) interactive media environment. The voxel-based representation includes a number of individual voxels that together represent the environment. The voxelizer can also be configured to identify a plurality of blocked voxels that intersect visual elements of the 3D interactive media environment. The pathing analyzer can be configured to determine, for the clear voxels, audio path information representing a path of clear voxels between the voxel and the location of the listener. The audio path information can be used to adjust sounds emitted by sound emitters in the media environment to realistically reflect the distances the sound travels to reach the listener.

Abstract: The subject disclosure is directed towards calibrating sound pressure levels of speakers to determine desired attenuation data for use in later playback. A user may be guided to a calibration location to place a microphone, and each speaker is calibrated to output a desired sound pressure level in its current acoustic environment based upon the attenuation data learned during calibration. During playback, the attenuation data is used. Also described is testing the setup of the speakers, and dynamically adjusting the attenuation data in real time based upon tracking the listener's current location.

Abstract: An apparatus for determining the integrity of a tube is provided. The apparatus includes: a body having an extension mechanism and configured to be inserted into the tube; and a flexible eddy current sensor including a flexible housing coupled to the body via the extension mechanism, and one or more coils disposed in the flexible housing. The flexible housing is selectively extendable via the extension mechanism between a first position and a second position. The one or more coils are farther away from the body when the flexible housing is in the second position than when the flexible housing is in the first position. The one or more coils electrically couple with an interior surface of the tube when the flexible housing is in the second position, and the flexible eddy current sensor is operative to selectively induce electrical currents within the tube via the one or more coils.

Abstract: The subject disclosure is directed towards a pre-cognitive interactive music system that dynamically generates and adjusts music based on a user's interactions with a videogame or other interactive system. When a user is predicted as getting close to an upcoming event, audio clips are dynamically selected (e.g., via metric modulation) based upon an estimated time to reach the event. The audio clips are stitched together and played as prelap music as the user approaches the event, and the clips may be varied if the estimated time changes due to user interaction. Drawdown music is similarly selected as the user completes or moves away from an event. Also described is the changing of the playing rate to adjust the music, and the use of harmonic modulation to change the music's key over time to increase or lower perceived suspense as the user approaches the event or moves away from it, respectively.

Abstract: A damper assembly for a fuel pump includes at least one diaphragm assembly formed by joining two metal diaphragms to respective two sides of an imperforate central plate, thereby creating a pair of closely spaced diaphragms, each acting upon its own gas volume. Preferably, the diaphragm assembly has (a) a circular or polygonal central plate, (b) a first circular diaphragm having a rim portion sealingly secured as by welding to the plate and a relatively thin, flexible, convex portion projecting from one side of the plate and defining a first pressurized gas volume, and (c) a second circular diaphragm having a rim portion sealingly secured as by welding to the plate and a relatively thin, flexible, convex portion projecting from the other side of the plate and defining an independent second pressurized gas volume. The diaphragm assembly can be supported radially inside, outside, or on the weld.

Abstract: A clamping and seal loading technique for securing the plunger sleeve to the pump housing of a single plunger fuel pump. This is achieved by providing a load ring between a sleeve retainer and the sleeve, such that the axial force applied by the retainer during installation and attachment to the plunger bore wall of the housing, is distributed more evenly on the sleeve and the sealing surface of the sleeve against the housing adjacent to the pumping chamber. The even distribution of force minimizes misalignment of the sleeve and thus maintains concentricity between the sleeve and the plunger.

Abstract: Pump piston seizures caused by excessive side loads produced by the uneven loading of a large piston return spring are prevented by separating the tappet return function from the piston return function, thereby minimizing the spring force acting on the piston. Preferably, a stronger, heavier load outer spring is mounted between the pump body and the tappet, such that it imparts no load and therefore no side loads to the pumping piston. A weaker, lighter load inner spring imparts less side load to the pumping piston than a conventional piston return spring, because the inner spring need not carry any tappet load. During both the pumping and charging strokes of the piston, the piston return spring can assist the tappet return spring, but the tappet return spring does not assist the piston return spring.

Abstract: A stent crimping system and method for use in preparing a bifurcation catheter assembly for use in a patient. The catheter assembly includes main and side catheter branches and a stent. The stent includes a side branch aperture through which the side catheter branch extends. The stent is crimped onto the main and side catheter branches with a crimping mechanism in two crimping steps. In the first crimping step, only a distal end portion of the stent is crimped while the side catheter branch remains extending through the side branch opening of the stent and remains positioned outside of the crimping mechanism. In a second crimping step, the entire stent is crimped with the crimping mechanism.

Abstract: Pump piston seizures caused by excessive side loads produced by the uneven loading of a large piston return spring are prevented by separating the tappet return function from the piston return function, thereby minimizing the spring force acting on the piston. Separate and distinct biasing means perform the respective functions. Preferably, a stronger, heavier load outer spring is mounted between the pump body and the tappet, such that it imparts no load and therefore no side loads to the pumping piston. A weaker, lighter load inner spring imparts less side load to the pumping piston than a conventional piston return spring, because the inner spring need not carry any tappet load. During both the pumping and charging strokes of the piston, the piston return spring can assist the tappet return spring, but the tappet return spring does not assist the piston return spring.
