    Abstract: A method of recovering audio signals and corresponding apparatus according to an embodiment of the present invention using video or other sequence of images enables recovery of sound that causes vibrations of a surface. An embodiment method includes combining representations of local motions of a surface to produce a global motion signal of the surface. The local motions are captured in a series of images of features of the surface, and the global motion signal represents a sound within an environment in which the surface is located. Some embodiments compare representations of local motions of a surface to determine which motions are in-phase or out-of-phase with each other, enabling visualization of surface vibrational modes. Embodiments are passive, as compared to other forms of remote audio recovery that employ active sensing, such as laser microphone systems.

  • Patent number: 9019795
    Abstract: An object is measured to record the relative surface coordinates. Then, a portion of the object “the front side” immersed in a fluid is imaged by directing a sonar pulse at the object and recording sonar signals reflected from the object with a sonar imaging array. Then, the recorded relative surface coordinates are iteratively fit to coordinates calculated from the sonar image. Thereafter, the coordinates of the surface of the “backside” of the object that is not observable in the sonar image are known, and a computer generated image of the backside is stitched to sonar image so that the object can be viewed from a plurality of viewpoints separated from the sonar imaging array.

  • Publication number: 20150078126
    Abstract: A system and computer program product for seismic imaging implements a seismic imaging algorithm utilizing Reverse Time Migration technique requiring large communication bandwidth and low latency to convert a parallel problem into one solved using massive domain partitioning. Since in RTM, both the forward and reverse wave propagation is iteratively calculated on time step increments, the method implements methods that includes partitioning memory between computation and intermediate results to optimize an RTM computation. The methods make maximum use of the memory to either eliminate storing the snapshot wavefield data to disk, or hide all or a significant portion of the disk I/O time. Furthermore, the schemes can provide the flexibility to vary a number of iterations (step size) for each snapshot to be kept in the memory. If any of the given conditions changes during the process, maximum usage of the available memory is ensured.

  • Publication number: 20150071031
    Abstract: A progressive beamformer in an imaging system includes a number of stages. A first stage delays and combines a number of received data streams to align the streams to a point of interest on a first beamline. The first stage feeds a number of subsequent stages that operate to buffer and re-delay at least a portion of the data streams received from a previous stage in order to align the data streams to a point of interest on a new beamline. In one embodiment, each stage operates to reduce the number of data streams that are passed to a subsequent stage without suffering from grating lobes. A beam reclamation process includes a number of stages that receive data streams from end elements in order to produce reclaimed beams that are added to beamline produced in a mainline beamforming process in order to produce output beamlines.

    Abstract: Techniques for navigating a high temperature low visibility environment are supported. A system may employ appropriate sonar signals to determine and display the location or distance to remote structures that may be obscured in the high temperature low visibility environment. Firefighters, military personnel, and other individuals that must navigate through obscured, high temperature environments may interact with suitable devices, such as a handheld device, to access and display the approximate location or distance of the remote structures or pathways. These devices may facilitate effective navigation of high temperature low visibility environments, thereby minimizing the risk of traumatic or fatal bodily injuries posed by the dangerous conditions.
