A downscan imaging sonar utilizes a linear transducer element to provide improved images of the sea floor and other objects in the water column beneath a vessel. A transducer array may include a plurality of transducer elements and each one of the plurality of transducer elements may include a substantially rectangular shape configured to produce a sonar beam having a beamwidth in a direction parallel to longitudinal length of the transducer elements that is significantly less than a beamwidth of the sonar beam in a direction perpendicular to the longitudinal length of the transducer elements. The plurality of transducer elements may be positioned such that longitudinal lengths of at least two of the plurality of transducer elements are parallel to each other. The plurality of transducer elements may also include at least a first linear transducer element, a second linear transducer element and a third linear transducer element.

Described herein are implementations of various technologies for a method and apparatus for displaying marine electronic data. In one implementation, a non-transitory computer-readable medium having stored thereon computer-executable instructions which, when executed by a computer, causes the computer to perform various actions. In one implementation, the actions may include displaying a plurality of possible marine electronic data types to be displayed. A selection to display one of the plurality of possible marine electronic data types in the plurality of possible marine electronic data types may be received. A plurality of possible combinations of marine electronic data types to be displayed with the one of the plurality of possible marine electronic data types may be displayed. A selection from the plurality of possible combinations may then be received. A combination of marine electronic data that correspond to the selection from the plurality of possible combinations may be displayed.

A sonar system using frequency bursts. A sonar system for use with a vessel may include a sonar module having a transmitting element configured to generate a transmit signal, where the transmit signal comprises one or more bursts, and where at least one burst comprises a first portion having a first frequency and a second portion having a second frequency different than the first frequency. The sonar system may also include a transducer array in communication with the sonar module, where the transducer array is configured to (i) receive the transmit signal from the transmitting element, (ii) produce one or more sonar beams based on the first frequency and the second frequency, and (iii) receive one or more sonar return signals from an underwater environment.

A method of processing geo-statistical data includes piloting a watercraft with a monitoring system on a water body, measuring depths of the water body, elevations of the watercraft, and positions of the watercraft using the monitoring system. The method also includes aligning the depths and the elevations with the positions, creating an average elevation using the elevations, and creating a contour map from the depths, positions, and the first average elevation.
摘要:
A non-transitory computer-readable medium having stored thereon a plurality of computer-executable instructions which, when executed by a computer, cause the computer to: receive a user input at a remote computer communicably coupled to a host computer over a network; and display one or more residue indicators on a screen of the remote computer indicating receipt of the user input by the remote computer. The one or more residue indicators are displayed for a period of time approximately equal to a system latency time. The computer-executable instructions are further configured to cause the computer to receive output data from the host computer based on the user input; and display the output data on the screen of the remote computer.

An apparatus for synchronizing cursor events may include a processor. The processor may be configured to receive an indication of a cursor event of a cursor presented within and associated with a sourcing window of a user interface that also includes a sourced window, wherein the cursor of the sourcing window indicates a geographical location within the geographical area presented by the sourcing window. Additionally, the processor may be configured to communicate information reflecting the cursor event to the sourced window. The processor may further be configured to subject the cursor of the sourced window to the cursor event reflected by the information to thereby synchronize a cursor event of the cursor of the sourced window with the cursor event of the cursor of the sourcing window, wherein the cursor of the sourced window indicates the geographical location indicated by the cursor of the sourcing window.
