摘要： Disclosed herein are system, method, and computer program product embodiments for accurately mapping audio to a visual image on a display device. An embodiment operates by, based on an identified virtual representation of the remote venue, modifying audio received at a local venue to produce a first and second modified audio. Thereafter, the first and second modified audio is correlated to a first and second portion of a prestored image. Afterward, the first and second portion of the prestored image is presented on a first and second portion of the display device's curved screen, and the first and second modified audio is provided on a first and second audio device, respectively, such that the first and second modified audio is provided to the first and second regions of the local venue synchronously with the first and second portions of audio.

摘要： A resistive skin shell for an acoustic panel or inner wall of an aircraft air intake, comprising an alternation, in a transverse direction, of perforated metal bands and of composite solid bands extending in a longitudinal direction. The perforated metal bands and the composite solid bands form a smooth outer face configured to be in contact with an aerodynamic stream, and a crenelated inner face. The composite solid bands have a thickness greater than the perforated metal bands. Since the perforations are provided in metal bands, which are intrinsically resistant to wear and erosion, the future proofing of the acoustic performance of the resistive skin is guaranteed. Since the composite solid bands, which are thicker, can ensure the mechanical strength of the skin, the thickness of the perforated metal bands can be reduced, allowing perforations with dimensions that are also reduced, having a lower impact on drag.

摘要： A passive horn integrally formed by using liquid silicone rubber, includes a first outer casing, a second outer casing, an inner casing and an iron piece. The first outer casing includes a sealing ring, a folding ring and a vibrating membrane, and the sealing ring, the folding ring and the vibrating membrane are integrally injection molded into the first outer casing. A groove is disposed in the second outer casing, and the first outer casing is disposed in the groove. The back surface of the vibrating membrane is provided with a casing groove, which is sequentially embedded with the inner casing and the iron piece. A preparation method of a passive horn integrally formed by using liquid silicone rubber, under the condition of integrated injection molding, may improve the yield rate, ensure product quality, save assembly time and labor cost, and improve production efficiency.

摘要： Systems and methods are disclosed for performing ultrasound imaging using biphasic driving and/or reception for ferroelectric ultrasound elements having propagation and lateral electrode pairs. Electrode pairs are driven using biphasic drive signals, where the drive signals applied to the respective pairs of electrodes are provided with a phase difference therebetween, and where a time delay may be added between the drive signals to further increase the power of the emitted ultrasound. In some example embodiments, passive determination of the direction and/or location of an acoustic source relative to a multiaxial ultrasound transducer is determined based on the voltages detected at the propagation electrodes and the lateral electrodes the multiaxial transducer, according to a pre-determined relationship between the electrode voltages and one or more directional angles. A plurality of multiaxial ultrasound transducers may be employed to improve the accuracy of the estimated direction and/or location of the acoustic source.

摘要： The spin-air speaker is an innovative sound generation and manipulation device, primarily characterized by a modulated spinning disc with a tailored hole pattern and a mechanism for controlled airflow. This technology leverages a precision motor assembly, which includes options such as a stepper motor or a motor/encoder combination, to modulate the disc's rotation speed and pattern. The invention's uniqueness lies in its ability to produce a wide range of sound frequencies and patterns, adjustable through the disc's hole pattern. A notable application of the spin-air speaker is in the field of fire suppression, where it utilizes specific sound frequencies to target and extinguish fires by achieving what is termed a “Pyrosonic lock” on the fire's fundamental and harmonic frequencies. The spin-air speaker's versatility extends to generating musical notes and melodies, and its capability to produce sounds below the human hearing range opens up possibilities for various non-entertainment applications, including but not limited to fire extinguishment.

摘要： This application discloses magnetically coupled integrated probes and probe systems, attachable to the robotic arms of a remotely operated vehicle to perform both cathodic protection (CP) voltage measurements and ultrasonic testing (UT) thickness measurements at an underwater surface. The integrated probe system can include a spring for coupling to an ROV end effector. An ultrasonic probe is disposed within and extends from the sleeve housing. A magnetic carrier, flux concentrator, and gimbal surround a portion of the ultrasonic probe, and one or more electrically conductive legs extend from the front surface of the gimbal to function as a CP probe. The legs are arranged about the ultrasonic probe, which has a flexible membrane exposed at the front surface of the gimbal, such that during inspection, at least one leg contacts the surface and the ultrasonic probe is sufficiently proximate to provide substantially simultaneous CP and UT measurements.
