  • Patent number: 10602119
    Abstract: It is contemplated that the present invention can provide methods and systems for the near-simultaneous frame acquisition from multiple cameras. This can be achieved in two different ways. If the cameras are set to work in triggering mode, the triggering of a first camera and a subsequent camera are adjusted by overlapping the trigger signals and image communication control signals of each camera in order to capture near-simultaneous images from each of the cameras. If the cameras are in video mode, they will be kept synchronous by using a common clock and starting them at the same time. As each camera generates frames, individual, corresponding frames are sampled from each camera in a sequential manner upon receiving a triggering signal. In this way, near simultaneous images can be sampled and saved from multiple cameras in video mode.

  • Patent number: 9187316
    Abstract: A sensor assembly including one or more capacitive micromachined ultrasonic transducer (CMUT) microarray modules which are provided with a number of individual transducers. The transducers include silicon device and backing layers joined by a fused benzocyclobutene (BCB) layer which defines the transducer air gap, and which are arranged to simulate or orient individual transducers in a hyperbolic paraboloid geometry. The transducers/sensor are arranged in a matrix and are activatable to emit and receive reflected beam signals at a frequency of between about 100 to 170 kHz.

  • Patent number: 8839683
    Abstract: The present invention provides a microscale pressure sensor that exhibits high sensitivity in a small form factor. The sensor is a bridged device in which a photonic crystal waveguide, surrounded by a photonic crystal slab, is suspended over a dielectric substrate. Under applied pressure, the photonic crystal waveguide is deflected toward the substrate, causing a decrease in optical transmission across the waveguide due to the coupling of the evanescent field of the guided mode to the dielectric substrate. In a preferred embodiment, the waveguide is coupled to a photonic crystal microcavity, which increases evanescent coupling.
