摘要： The methods and apparatus described herein optimally represent full 3D audio mixes (e.g., azimuth, elevation, and depth) as “sound scenes” in which the decoding process facilitates head tracking. Sound scene rendering can be performed for the listener's orientation (e.g., yaw, pitch, roll) and 3D position (e.g., x, y, z), and can be modified for a change in the listener's orientation or 3D position. As described below, the ability to render an audio object in both the near-field and far-field enables the ability to fully render depth of not just objects, but any spatial audio mix decoded with active steering/panning, such as Ambisonics, matrix encoding, etc., thereby enabling full translational head tracking (e.g., user movement) beyond simple rotation in the horizontal plane, or 6-degrees-of-freedom (6-DOF) tracking and rendering.

摘要： A two-channel phase-amplitude stereo encoding and decoding scheme enabling flexible and spatially accurate interactive 3-D audio reproduction via standard audio-only two-channel transmission. The encoding scheme allows associating a 2-D or 3-D positional localization to each of a plurality of sound sources by use of frequency independent inter-channel phase and amplitude differences. The decoder is based on frequency-domain spatial analysis of 2-D or 3-D directional cues in a two-channel stereo signal and re-synthesis of these cues using any preferred spatialization technique, thereby allowing faithful reproduction of positional audio cues and reverberation or ambient cues over arbitrary multi-channel loudspeaker reproduction formats or over headphones, while preserving source separation despite the intermediate encoding over only two audio channels.

摘要： A method and device are described to process an event on an audio rendering device. The method may comprise rendering a first audio stream via at least a first audio signal in a first audio playback channel and a second audio signal in a second audio playback channel and monitoring occurrence of the event with an associated second audio stream. Upon occurrence of the event, the first audio signal may be panned to the second audio playback channel, the first audio signal being mixed with the second audio signal in the second audio playback channel. The second audio stream is then rendered via the first audio playback channel.

摘要： A system and method are described for rendering a left rear surround input signal at a left rear virtual speaker location and rendering a right rear surround input signal at a right rear virtual speaker location. The method includes phase shifting the left rear surround input signal by a first phase shift. The right rear surround input signal is phase shifted by a second phase shift. The phase shifted left rear surround input signal is phase shifted using an HRTF selected to render the left rear surround input signal at the left rear virtual speaker location. The phase shifted right rear surround input signal is transformed using an HRTF selected to render the right rear surround input signal at the right rear virtual speaker location.

摘要： A platform trailer includes a load carrying main frame and an elongated loading deck supported by the main frame and defining a generally planar surface upon which cargo may be loaded. An elongated side rail is attached to at least one of the loading deck and the main frame so that the side rail is disposed along a longitudinal edge of the trailer. The side rail defines an upwardly opening channel extending along the longitudinal edge. The channel has a planar central portion substantially parallel to a plane defined by an upper horizontal surface of the loading deck and opposing side portions extending vertically upward from the central portion.

摘要： An improved cargo restraint attachment assembly for use with a platform trailer includes a body having an interior side and an exterior side opposite thereto. A first section is adjacent to the interior side and configured to attach the body to a loading deck of the platform trailer so that the body extends outwardly from and along at least a portion of a longitudinal edge of the loading deck. A second section is configured to selectively secure the cargo restraint device at a desired position with respect to the longitudinal edge. The assembly may secure at least one cargo restraint device at an angle with respect to a horizontal plane to minimize bending moment on the cargo restraint device from force applied thereto by engagement with a load on a loading deck of the platform trailer.

摘要： Embodiments of a virtual surround-sound system and methods for simulating surround-sound are generally described herein. Other embodiments may be described and claimed. In some embodiments, a processing module may include spatial processor spatially processes surround-left and surround-right channel signals and front-left and front-right channel signals and combines the spatially-processed signals for providing to drivers of center speaker after crosstalk cancellation and combining with a center-channel signal.

摘要： A ported pressure relief valve (10) used in an automotive fuel system (F) includes an unrestricted constant bleed orifice (32) for routing pressurized fuel from a fuel pump (P) back to a fuel source (T, M) when an engine (E) is running. A check valve (30) prevents flow from a fuel system back to the fuel source when the engine is off, so to retain sufficient pressure in the delivery system that the engine will readily start when cranked. A pressure relief valve (50) drains fuel from the delivery system back to the source of fuel in response to a pressure build up in the fuel delivery system above a predetermined pressure level so to prevent an overpressure condition which would otherwise damage the fuel delivery system.
