Abstract: An automatic trim system for a jet propulsion watercraft is provided. Control electronics are in communication with a steering angle sensor to monitor the steering angle of the watercraft, and evaluate a target setting for the trim taking the steering angle into consideration. Control signals are sent to an appropriate actuating device for adjusting the trim angle accordingly.

Abstract: A commonly actuated trim and reverse system for a jet propulsion watercraft is provided. The system includes a movable actuator connected to a movement transfer mechanism. The movement transfer mechanism is operable to adjust both the trim angle of the steering nozzle of the watercraft and the orientation of the reverse gate, as a function of the movement of the actuator. Control electronics evaluate the target steering for the trim angle and gate orientation and control the movement of the actuator accordingly.

Abstract: An electronically assisted reverse gate system for a jet propulsion watercraft is provided. Control electronics are in communication with the operator interface of the watercraft to obtain commands from the operator, such as a selection between a forward, reverse or neutral mode, a braking command or a slow mode. The control electronics evaluates the target setting for these commands. This evaluation is made taking into consideration the operating conditions of the watercraft. Control signals are sent to an appropriate actuating device to adjust the gate orientation accordingly.

Abstract: A method and system for indicating a status of a load of a sub-system in a marine vehicle where the load is controlled by a switch provided on a steering wheel of the marine vehicle.

Abstract: A method and system for powering at least one switch provided on the steering wheel assembly of an off road vehicle. The method or system includes providing a rechargeable accumulator in the steering wheel assembly and powering the switch from the accumulator. The method or system also includes an energy source for recharging the accumulator along with the step of comparing a detected energy level and/or a detected time elapsed to a threshold value corresponding to the energy level being sufficient to power the switch and enable its use. Said aforementioned step is utilized to determine if there is energy sufficiency or an energy insufficiency in the accumulator. If the comparison yields an energy insufficiency, the energy source may be instructed to recharge the accumulator, and hence increase its energy level. The above discussed steps may be repeated to ensure the sufficiency of the energy level to power the switch.

Abstract: According to a first broad aspect of the present invention, there is provided a method and system for indicating a status of a subsystem controlled by a switch provided on a steering wheel of a marine vehicle. The method and system comprise: providing a switch for the subsystem on the steering wheel of the marine vehicle; providing a status indicator for the switch; detecting an activation of the switch; transmitting a command to the subsystem in the marine vehicle in response to the activation; detecting an operation status of the subsystem in response to the command; and activating the status indicator to indicate information of the operation status.

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.

Abstract: A signaling device for a marine vehicle having a fuel tank, a fuel level value detected in the fuel tank, and a blower to evacuate fuel fumes. The signaling device comprises: a fuel level variation detector; a refueling detector for detecting a fuel level variation corresponding to a refueling event; a refueling signal generator for generating a refueling signal when the refueling event is detected; and a refueling activator for activating the blower, and/or an indicator of refueling for the user, using the refueling signal. A signaling method for the marine vehicle comprising: detecting a variation of the fuel level value over time; detecting a fuel level increase in the variation to correspond to a refueling event; generating a refueling signal when the refueling event is detected; and activating the blower, and/or an indicator of refueling for the user, using the refueling signal.

Abstract: A transponder system for motor vehicle, used both as a RKE system and as a kill switch type safety system, is described herein. The transponder system includes an electronic lock assembly provided with a housing, an interrogator circuit and a coil antenna. The transponder system also includes an electronic key provided with a housing made of a slightly resilient material, a transponder circuit, and a coil antenna. The key assembly may be releasably mounted to the lock assembly since the housing of the key assembly is made of a slightly resilient material. Continuous interactions between the electronic lock and the electronic key are required for the continuous operation of the engine of the vehicle.
