摘要:
A personal alarm system includes a monitoring base station and one or more remote sensing units in two-way radio communication. An electronic handshake between the base station and each remote unit is used to assure system reliability. The remote units transmit at selectable power levels. In the absence of an emergency, a remote unit transmits at a power-conserving low power level. Received field strength is measured to determine whether a remote unit has moved beyond a predetermined distance from the base station. If the distance is exceeded, the remote unit transmits at a higher power level. The remote unit includes sensors for common hazards including water emersion, smoke, excessive heat, excessive carbon monoxide concentration, and electrical shock. The base station periodically polls the remote units and displays the status of the environmental sensors. The system is useful in child monitoring, for use with invalids and with employees involved in activities which expose them to environmental risk. Alternative embodiments include a panic button on the remote unit for summoning help, and an audible beacon on the remote unit which can be activated from the base station and useful for locating strayed children. In another embodiment, the remote unit includes a Global Positioning System receiver providing location information for display by the base station.

The disclosure relates to systems, methods and apparatus for member or man overboard detection, tracking and recovery used for analyzing conditions on and/or around a ship or vessel located on a body or water. The member overboard detection, tracking and recovery system generally includes the ship, members of the ship, transmitting device, a ship based member overboard detection system, a member overboard (when in the detection, tracking and recovery mode), and an overhead receiving and communication system. The member overboard detection, tracking and recovery system may also include a marking/tracking device, and/or a recovery craft.

A wireless water ski handle system used with a personal water ski towing watercraft that includes a handle component that selectively attaches to a standard water ski handle and contains a manual control module and a wireless transmitter. The control module includes directional control buttons, power ON and OFF buttons, and power Up and Down buttons. Located in the watercraft is a wireless receiver that communicates with the transmitter. Coupled to the receiver is a self-correcting propulsion and steering system that senses undesirable changes to the watercraft's motion caused by the water-skier when pulled by the watercraft. When a difference is detected, a command module located in the watercraft automatically controls the watercraft's propulsion and steering systems so the watercraft follows the desired path and velocity. The system also includes an auto-back tracking feature that automatically reduces power to the last known marked geographic point the skier was upright.

A security system for automatically detecting and signaling the event of a person falling overboard from a vessel into a body of water includes a radio frequency identification (RFID) tag worn by each passenger onboard a vessel, one or more RFID readers placed surrounding the hull of the vessel, a control unit onboard the vessel wherein the RFID readers are individually connected, and an alarm system. When a person who is wearing the RFID tag falls overboard, he or she would inevitably pass through one or more of the RFID readers placed surrounding the hull of the vessel. One or more RFID readers read the information contained in the RFID tag, and said information is transmitted from the RFID reader to the control unit. The control unit records the time and location of the event, and activates an alarm system for facilitating the rescue of the person.

There is elucidated a safety system for a marine vessel. The vessel includes two engines coupled to propellers for propelling the vessel through water. The vessel is provided with a digital anchor in communication with the two engines for maintaining the vessel substantially at a defined location when the anchor is activated. The safety system includes a sensor assembly coupled to a data processing assembly for sensing a region of said water at least partially surrounding the vessel for detecting one or more persons present in the region and for modifying operation of the digital anchor in response to the one or more persons being detected. The invention is of advantage in that the digital anchor is capable of responding to the one or more persons being present in the water and thereby reducing a risk of injury or loss of life when the digital anchor is employed.

The invention provides for exchanging a complete luminous unit (24) instead of exchanging the individual components such as a battery (64). For this purpose, at least one energy-saving light-emitting diode (56) as luminous means, a battery (64) and a magnetically actuable reed contact (66) serving as switching element are combined as luminous unit (24). The use of a cost-effective light-emitting diode (56) and a battery (64) formed in space-saving fashion in accordance with the low power demand of the light-emitting diode (56) permits a compact configuration of the luminous unit (24). The fact that the luminous unit (24) can be inserted into the floating body (22) as a unit and can be exchanged as a unit obviates a complicated battery change or change of luminous means entailing the risk of leaks.

The apparatus of the present invention has a shell, an indicator and straps. The shell has flanges at the top and bottom, respectively, constricting the hole size at the ends of the shell. The shell can be comprised of a body and a cap. The indicator is in telescoping engagement with the shell. The indicator has two ends. The first end of the indicator protrudes from the second end of the shell. A weight is at the second end of the indicator. The weight has a sidewall with an outer periphery greater in size than the inner periphery of the shell ends. The straps are used to secure the apparatus to a person. The indicator extends from the shell when the person enters the water. The indicator, aided by the weight, retracts into the shell when the person exits the water. The shell can have wings.
