Abstract: A navigation device is disclosed that provides navigational guidance to boats needing to cross a boundary line at a milestone event time. Port and starboard laylines and guidelines may be displayed with the boundary line using wind direction data. The port and starboard layline angles may change with the wind direction, while their lengths may represent a distance traversed by the boat tacking at the port and starboard layline angles for a target time period at a target speed. A predictor line may be displayed extending from the boat in the direction in which the boat is traveling and may have a length indicating a distance traversed by the boat at its current speed until the milestone event time. The predictor line length and color may provide feedback regarding whether the boat will cross the boundary too early or too late given its current speed and direction.

Abstract: A marine sonar display device comprises a display, a sonar element, a memory element, and a processing element. The display presents sonar images. The sonar element generates a sonar beam and presents transducer signals. The processing element is in communication with the display, the sonar element, and the memory element and receives the transducer signals, calculates sonar data from the transducer signals and generates a three-dimensional view of a portion of the body of water, wherein the view includes a plurality of sonar images. Each sonar image is generated from sonar data derived from a previously-generated sonar beam and includes representations of underwater objects and a water bed. The processing element also generates a cursor plane and a cursor positioned thereon, both of which appear on the three-dimensional view. The processing element further controls the display to present the three-dimensional view, the sonar images, the cursor plane, and the cursor.

Abstract: Various techniques are described that relate to the manner in which marine devices may generate and display a water depth contour map while navigating a body of water. The contour map includes contour lines associated with determined contour line data that indicate geolocations of underwater terrain existing at depths of the body of water specified by the contour lines. A boundary enclosing a region of interest for the body of water may be determined and the contour map may include contour lines determined using the determined contour line data within the region of interest. The boundary may correspond to a natural shoreline along the perimeter of a body of water or a portion of the body of the water. The boundary corresponding to a shoreline may be automatically identified based on a stored map by identifying geographic locations along the perimeter of the body of water.

Abstract: Techniques are provided for implementing a system that can perform a range estimation of a target object at power levels both below and above an pre-defined power threshold. In embodiments, the system first performs a lower-power measurement, which may be sufficient to estimate the range to the object. If the low-power measurement is unsuccessful, the system then performs a fault check to ensure proper operation of the device. If the fault check is passed, the system may then perform a high-power measurement of the range to the object. Results may be provided to a user by a visual display.

Abstract: An omnidirectional camera is disclosed that records spherical video associated with a particular focal direction while in motion. The omnidirectional camera may implement one or more sensors and location-determining components to facilitate the recorded spherical video being subsequently correlated to an orientation and location of the omnidirectional camera during recording in a time-wise fashion to provide several enhancements during playback. These enhancements include reorienting the spherical video to a new focal direction. Data derived from the one or more sensors and location-determining components may be further utilized to overlay graphical objects onto the spherical video during playback to provide additional feedback.

Abstract: A coded-light communication device is described, in which the communication has an initial signal-to-noise ratio, which varies according to the lighting conditions. The device comprises at least one photodetector-type light receiver comprising an anode and a cathode and having an initial shunt resistance.

The anode and cathode are short-circuited by at least one short-circuit resistance arranged inside the photodetector, having a value selected so that the new value of the shunt resistance of the photodetector resulting from the connection of the initial shunt resistance and the short-circuit resistance gives the communication device a new resultant signal-to-noise ratio which remains substantially independent of the intensity of the non-coded light.
