| 20090251321 | Aqua Alert Swimming Monitor for the Prevention of Accidental Drowning - A drowning alarm and position marking system is described herein. The Aqua Alert is a system for detecting the drowning of an individual and subsequent generation of an alarm to alert a parent, lifeguard or by-standers. The system consists of two different units, a portable unit worn by the swimmer and a base station which is worn by a parent/supervisor or located on the beach, pool or boat. The buoyant portable unit transmits a signal which may be ultra-sonic, sub-sonic, audio or optic, but preferably radio frequency in nature. This signal is transmitted semi continuously until the portable unit is submerged in water in which case the signal is cut off from the base station due to the attenuating effects of being submerged in water. The base station will generate an alarm such as a siren or visual means or both if the signal from the portable unit is not received for a period of approximately 10 seconds, thus operating in a fail-safe condition. The portable unit has an on board means of sensing submersion in water and after being submerged for approximately 10 seconds will release a stored line which will allow the unit to remain attached to the drowning individual but float to the surface where both a highly reflective coating and a super high intensity LED will indicate the position of the drowning individual. The system may also act as a proximity monitor as the base station will alarm if the swimmer's distance exceeds the transmitting range of the portable unit, which is approximately 200 feet. | 10-08-2009 |
| 20090303055 | ABOVE-WATER MONITORING OF SWIMMING POOLS - An above-water system provides automatic alerting for possible drowning victims in swimming pools or the like.

| 20100060462 | Led rescue light - The present invention describes a rescue light with a LED light source that meets a minimum requirement of 0.75 candela (cd) of intensity, over a full hemisphere of visibility, with a duration of 8 hours or more. The invention requires only 3 volts of battery power from relatively small batteries, making the invention small and lightweight. In one favorite embodiment the LED is a specially constructed device that uses a blue LED die enclosed with a uniform layer of phosphor on the outer surface of the LED body, which provides an equally bright white light in all directions. Due to the low power requirements of the LED, the device can easily produce white light over an entire hemisphere at the required brightness level for longer than the required amount of time. In another favorite embodiment, a power LED with a large viewing angle is powered with a relatively high current, so as to meet the requirements for intensity over the entire hemisphere, but the high current is applied for only short periods of time in order to meet the requirement for duration. In this second embodiment, a novel switching arrangement is provided to allow the user to turn the LED on and off by changing positions of a movable member of the device, where the original position of the movable member is independent of the operational state of the device. In a third favorite embodiment, multiple LEDs are incorporated for greater visibility, and the operational state of the device is changed by pressing a momentary switch. In all of the described embodiments, a water sensitive switch may be provided to activate the LED on contact with a body of water. | 03-11-2010 |

| 20110241887 | Waterproof optically-sensing fiberless-optically-communicating vitality monitoring and alarming system, particularly for swimmers and infants - The vitality of a swimmer, or of a child, is monitored by a periodically-activated micro-powered solar- and battery-powered waterproof microminiaturized (1) optical sensor of heart activity, electrically connected to (2) a microprocessor monitor, for jointly determining when a person's heart activity has stopped. When and if required, the microprocessor causes to be transmitted, through water a blue-green light alarm signal. When this optical alarm signal is received by an optical receiver/alarm in air, the receiver/alarm produces an audio and/or visual alarm that, when sensed by a human, potentially timely permits rescue and resuscitation of the swimmer, or the child.
