Display system for marine vessel
First Claim
1. In a marine vessel having a marine propulsion unit including an engine, the improvement comprising a display system, said display system comprising means for detecting the cumulative engine operating time, means for detecting a plurality of other operating and navigating conditions, a single displaying device comprising a variable display, and a cumulative engine operating time display for displaying the cumulative engine operating time, said single displaying device further displaying information regarding at least one of the plurality of other detected operating and navigating conditions, said display system further comprising a control device including an A/D converter, a processing unit which receives the output of said cumulative operating time detecting means, an LCD driver which receives the output of said processing unit, the output of said LCD driver being received by said cumulative engine operating time display, a main switch for turning on and off the variable display and wherein said processing unit further comprises an AND circuit, means for cumulating the cumulative engine operating time, and a memory, such that when the engine is running, on-off data from said switch and the output from said cumulative operating time detecting means are transmitted to said means for cumulating the cumulative engine operating time through said AND circuit, the output of said cumulating means being transmitted to said memory and to said LCD driver.

Abstract
A first embodiment of the invention provides a display system which is adapted to be embodied in a marine vessel having marine propulsion unit which is pivotally attached thereto for trim movement about a generally horizontally extending trim axis. The display system includes a trim angle sensor for detecting the trim angle of the propulsion unit and a trim angle display, preferably including both a graphical and a digital display, for precisely displaying information regarding the detected trim angle of the propuslion unit. Other sensors for detecting various other operating and navigating conditions of the vessel can be incorporated into the display system and a single displaying device can be used for displaying trim angle information and information regarding such other detected conditions. Another embodiment of the invention provides a display system which is adapted to be embodied in a marine vessel having a marine propulsion unit including an engine. This display system includes a cumulative engine operating time sensor, preferably in the form of a charge or pulser coil, other sensors for detecting varous other operating and navigating conditions of the vessel, and a single displaying device for displaying the cumulative engine operating time and information regarding at least one of the aforementioned other detected conditions.
