Secondary power supply system and method of activating subsystems from a vehicle steering wheel
First Claim
1. A method for powering at least one subsystem switch provided on a steering wheel assembly of a marine vehicle, comprising:
- providing a rechargeable accumulator having an energy level, in said steering wheel assembly;
powering said switch from said accumulator;
providing an energy source in said marine vehicle, able to induce recharge energy into said accumulator;
comparing one ofa detected value of said energy level with an energy threshold value corresponding to a value of said energy level sufficient to power said at least one switch and enable its use, anda detected time elapsed since recharge energy was induced into said accumulator with a time threshold value corresponding to a time after which said energy level equals said energy threshold value,determining one of a sufficiency and an insufficiency of said energy level upon said comparison;
if said comparison yields said insufficiency, instructing said energy source to recharge said accumulator, thereby increasing said energy level; and
repeating said steps of comparing, determining, and instructing thereby ensuring said sufficiency.

Abstract
A method and system for powering at least one switch provided on the steering wheel assembly of a marine vehicle. A rechargeable accumulator is provided in the steering wheel assembly. The switch is powered from the accumulator. An energy source is provided for recharging the accumulator. A detected energy level and/or a detected time elapsed is compared to a threshold value corresponding to the energy level being sufficient to power the switch and enable its use and determine if there is energy sufficiency or an energy insufficiency in the accumulator. If the comparison yields an energy insufficiency, the energy source is instructed to recharge the accumulator, and hence increase its energy level.

13. A system for powering at least one subsystem switch provided on a steering wheel assembly of a marine vehicle, comprising:
-
a rechargeable accumulator in said steering wheel assembly, capable of supplying energy to said at least one switch, and having an energy level; an energy source in said marine vehicle able to induce recharge energy into said accumulator; a comparator for comparing one of an actual value of said energy level detected by a detector with a provided energy threshold value corresponding to a value of said energy level sufficient to power said at least one switch and enable its use, and an actual value of time elapsed since recharge energy was induced into said accumulator with a provided time threshold value corresponding to a time after which said energy level equals said energy threshold value, said time elapsed being monitored by a timer, and determining one of a sufficiency and an insufficiency of said energy level upon said comparison; and a controller for instructing said energy source to recharge said accumulator thereby increasing said energy level, if said comparison yields said insufficiency; wherein said comparator, and said controller are capable of continually repeating said comparing, determining, and instructing to ensure said sufficiency. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
