Warning Decal Strip at 2012 Bayliner Helm

This invention has to do with displaying warnings based on the actual situations and conditions the boat is encountering or anticipated to encounter soon.

Background Information

The effectiveness of conventional warning decals and placards on boats is reduced by: (1) The shear number of warnings displayed on the boat, (2) repetitive exposure to the same warnings, (3) some warnings fail to draw attention to themselves and thus are not read, (4) warnings are often not up front and prominent just before an action needs to be taken.

One method to minimize these difficulties is to display only those warnings relevant to the current situation. A reduction in the total number of warnings being repetitively constantly displayed at the same time reduces “warning noise” and results in more attention being focused on the most relevant warning(s) at that time.

The invention consists of four components or subsystems:

  • The display – where the warnings are shown
  • The sensors or gauges – many of them are already on the boat
  • The network – several boats already run CANbus systems
  • The software or logic system used to select which warning(s) to display
  • The computer / the brains – a computer system the software runs on, stores the warnings, reads the inputs (sensors), uses the software to decide which warning(s) to display, and issues the command to display specific warning(s).

Today, August 29, 2011, we, the Propeller Guard Information Center, posted five RFID (Radio Frequency Identification) invention disclosures. While they have other implications as well, they were primarily inspired by problems surrounding boat engine kill switches (emergency engine cut-off switches).

We (Polson Enterprises and the Propeller Guard Information Center) initially retained all rights to these inventions (including their use in non-boating applications). However, one year later (29 August, 2012) all five inventions were placed in the public domain.

Existing lanyard boat engine kill switches (emergency engine cut-off switches) are used to kill the engine if the operator falls overboard. Boats often begin spinning wildly in the “Circle of Death” after the operator has been ejected. A boat operator that falls overboard while the boat is underway may be struck repeatedly by the boat and/or propeller as the boat circles.

Lanyard boat kill switches are rarely used by boat operators due to the hassles of hooking them up. Sensor based kill switch systems such as Autotether and MariTech’s Virtual Lifeline and CAST have began to address some of the hassles involved with using lanyards. Our RFID tag based invention disclosures illustrate a different sensor based approach with some additional advantages.

Our five invention disclosures are: Read More→

Many cage type boat propeller guards focus on preventing people from contacting the propeller, not on moving people out of harm’s way. They form a nice physical barrier around the propeller with little regard for the damage that the barrier itself may cause to those struck while moving forward. Read More→
