  • Patent number: 12279748
    Abstract: An endoscopy system that includes a computer system with a high definition display monitor and a handheld portion. The handheld portion includes a re-usable handle portion and a single use portion that is configured to be disposed of following a single use. The single-use portion includes a substantially straight elongated cannula with an imaging module and illumination modules at its distal tip. The imaging module is mounted such that its direction of view (DOV) is at an oblique angle from the main longitudinal axis of the cannula.

  • Patent number: 11940361
    Abstract: The present disclosure provides an integrated collection, filtration, and analysis system which is configured to automatically collect fluid samples from a surrounding open water environment, isolate floating particles of a target size range, and perform analysis on the collected particles in-situ. The particles may also be filtered by one or more parameters other than size, and also provided herein is a two-stage vortex filter specially adapted to isolate floating particles of a desired density range from a fluid.

  • Patent number: 11712149
    Abstract: An endoscopy system that includes a computer system with a high definition display monitor and a handheld portion. The handheld portion includes a re-usable handle portion and a single use portion that is configured to be disposed of following a single use. The single-use portion includes an elongated cannula with an imaging module and illumination modules at its distal tip. The handheld portion includes multiple sensors that can detect and measure rotation of the cannula relative to the handle portion, and rotation of the entire handheld portion. The sensor data is used to correctly orient and display images captured by the imaging module onto the high definition display monitor.

  • Publication number: 20220187830
    Abstract: The present disclosure provides a system for autonomously controlling a fleet of carrier platforms on a water body surface, each carrier platform hosting and being configured to deploy and retrieve one or more sub-carriers for autonomously carrying out operations in a marine environment. The one or more carrier platforms and sub-carriers of the system each have navigation and positioning modules for coordinating movements and are also centrally managed via an intelligent central control system from which the operations of the fleet can be monitored and controlled. The present invention solves the retrieval issue presented by deploying unmanned sub-carriers in complex real-world environments. The invention provides for a modular retrieval system for unmanned sub-carriers.

  • Publication number: 20220138917
    Abstract: The present invention, in some embodiments thereof, relates to apparatus, system and methods for image distortion correction when scanning/imaging an air-water interface (AWI), or any such interfaces between two media including air and glass, among others. According to one embodiment, the apparatus comprises of a means of scanning a mean water level, and twos canners, wherein is set slightly above the water surface, and one positioned just below, with the scanners having an intersecting view of the AWI. A suitably trained machine learning algorithm recognizes key features from both the above-water and underwater scans, determines distortion from the AWI, make a correction of the distortion and automatically stitch the distortion-corrected scans together. According to another embodiment, the resulting single complete, accurate, and high-density point cloud of all surface profiles in, around, and below the AWI area.

  • Publication number: 20220080805
    Abstract: The present invention discloses an improved system of monitoring logistics involved in marine transportation. The proposed system with the help of data acquisition component, humidity control component, temperature control component, power component, microcontroller, and user device automatically regulate the required temperature and humidity level within preset threshold and also transmits the information to the user's device. This system also allows to add additional sensors and environmental control components including but not limited to ambient light, vibration, sound, movement, oxygen, chemical levels, and more. The system also provides a communication interface coupled to the onboard micro controller, where the communication interface being operative to transmit a monitoring update message to end user device, in response to a transmission instruction from the onboard microcontroller.
