摘要:
A marine navigation device comprises a location determining element, a display, a memory element, and a processing element. The location determining element determines a current geolocation of a marine vessel on a first body of water. The display displays a map representation. The memory element stores digital elevation model data and sonar data for a plurality of bodies of water. The processing element is in communication with the memory element and is configured to select the digital elevation model data or the sonar data from the memory element corresponding to the first body of water, calculate contour line data, the contour line data determining a plurality of contour lines, update the contour line data by selectively removing at least a portion of the contour lines, and generate a map representation including contour lines derived from the updated contour line data, and control the display to visually present the map representation.
摘要:
A marine multibeam sonar device comprises a processing element and a transmitter. The processing element generates a plurality of transmit transducer electronic signals and inverts a polarity of a first portion of the transmit transducer electronic signals. The transmitter is in communication with the processing element and includes a plurality of transmit electronic circuits and a plurality of transmit transducers. Each transmit electronic circuit receives and processes one of the transmit transducer electronic signals, wherein a first portion of the circuits re-inverts the polarity of the first portion of the transmit transducer electronic signals. The transmit transducers receive the processed transmit transducer electronic signals from the transmit electronic circuits and generate a sonar beam.
摘要:
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.
摘要:
A wearable electronic device utilizes indicators on a display screen, such as tick marks positioned around the perimeter of the display, to point to the bearing of a desired location such as a nearest airport when GPS is enabled. The electronic device may be implemented as an aviation watch that comprises a display device having a screen including a plurality of indicators arranged proximal to a perimeter of the screen. The aviation watch determines a direction of an airport that is nearest in proximity to the location of the aviation watch and activates a subset of the plurality of indicators of the screen, the subset of the plurality of indicators providing a directional bearing to the airport determined to be nearest in proximity to the location of the aviation watch.
摘要:
An apparatus or web server for assisting a user in selecting a route based on tracked popularity of routes traveled by other users and a desired user activity. The apparatus may include a memory for receiving and storing route data for routes previously traveled by a plurality of users and a processing device coupled with the memory for receiving desired route characteristic information from the user, including a desired activity type, such as running or cycling. The processing device may compare the desired route characteristics information with the route data, suggest at least one of the stored routes to the user based on the comparison, and visually indicate with a color-coded heat map a popularity of the routes suggested based on the comparison.
摘要:
A method of transmitting a destination along with the user's current location to a central viewing site allowing the user set or change their travel plan while they are on their trip and minimize bandwidth use on expensive or slow networks. A byproduct of this method is the transmission device can record the detailed path traveled by the user while transmitting enough user locations to give the viewer at the central viewing site a good indication of where the user has been. The detailed route traveled by the user is uploaded to the central viewing site when the transmission device is connected to a faster or less expensive network.
