Abstract: Systems, devices, and methods are provided for calculating a course for avoiding user identified criteria. A navigation device with route calculation capabilities includes a processor connected to an input and a memory that includes cartographic data and user identified criteria. A route calculation algorithm can be used to calculate a course between two or more waypoints based on the predefined user criteria of the cartographic data. Performing the route calculation algorithm includes analyzing the cartographic data with a preference for providing the course that identifies and avoids the user identified criteria. A display is connected to the processor and is capable of displaying the calculated route and cartographic data. The device is also adapted to dynamically analyze an area surrounding a present location for user identified criteria to avoid and display the results of the analysis.

Abstract: A sonar depth sounder device and method for processing echo signals, reflected from objects within a body of water, utilizes a processor, a memory, a display, and a keypad connected to the processor. The receiver receives sonar signals indicative of ambient noise in an underwater environment. The processor receives an electrical signal representative of the ambient noise, and calculates a detection threshold. The detection threshold is calculated by multiplying a scaling factor times the variance of the signal indicative of the ambient noise, and adding that product to the mean of the signal indicative of the ambient noise in the underwater environment. A transmitter then excites a transducer which emits sonar pulses into a body of water, and a receiver receives reflected sonar echo signals. When the intensity of the reflected sonar echo signals is less than the detection threshold, the reflected echo signals are eliminated from processing.
