Abstract: Embodiments are disclosed to calculate and store rock climbing navigational data using a rock climbing watch including a sensor array configured to measure an orientation of the rock climbing watch and a processor configured to calculate an angle between two rock face locations along a rock climbing route based upon an orientation of the rock climbing watch when it is pointed from a current rock face location towards another rock face location. A processor may determine route segments for traversing the rock climbing route. A processor may convert route climbing navigational data into a three-dimensional wireframe rock climbing navigational map including rock face locations, calculated distances and angles between rock face locations, and a rock climbing route. The rock climbing watch may present information to guide the user along a rock climbing route by displaying a graphical directional indicator and a distance to the next rock face location.

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: Characterization of a fitness monitor based on its operation enables a processor to account for variations in device operating modes and biometric characteristics of the user. The fitness monitor includes an emitter (e.g., LED) for transmitting light toward skin of the user, a receiver (e.g., photodiode) for receiving a reflection of the transmitted light, a photometric front end for generating a photoplethysmogram (PPG) signal based on the received reflection, and a processor configured to select an intensity level for the emitter based on a comparison of a determined component of the PPG signal and a reference value. The reference value, which may characterize the fitness monitor based on a determined variability or range of the PPG signal, may be utilized by the processor to improve or maintain the signal quality of the PPG signal to enable determination of a cardiac component and/or reduction of power consumption by the fitness device.
