A system and method for powering an ultraviolet (UV) water purification system utilizing a dynamo. A dynamo, operably attached to the UV water purification system, generates power from a rotatable crank which is actuated by a user around an axis of the rotatable crank. When the crank is rotated, the dynamo produces an electrical current that activates and powers the UV lamp, which in turn, produces UV light to purify the water. To ensure that the water has been purified appropriately, a microcontroller, employed within the UV water purification system, tracks both the 'on' time and the intensity of the UV lamp as the dynamo is cranked. Once the lamp has been 'on' at a sufficient intensity and for an appropriate period of time to administer a required dose of UV light, the microcontroller disables the lamp and provides the user with notification that the process has completed.

A wearable or portable intermittently operable hydration system includes a purification module that contains one or more solid state light emitting devices that are positioned in the path of hydrating fluid, or water, flow through the hydration system to a mouthpiece. The light emitting devices illuminate a photocatalytic material disposed within the flow path in order to react and create fluid-purifying hydroxyls. The lights are instant on devices with essentially no ramp-up required, and a sensor or the opening of a push-pull valve controls the turning on of the lights. The fluid flow path may run from a bladder in a backpack worn by the user, a sports bottle worn by or carried by the user or may be through a water filtration system that a user operates via a pump. The power for the purification module may come from batteries, solar cells, fuel cells, or power converted from pumping, winding, etc.

Photocatalytic intermittent flow-through purification module

The inventive optical sensor consists of an LED semiconductor material and elements (herein after the LED components) surrounded by a transparent encapsulant that allows much of the light produced by the LED components to pass while a certain small percentage of the light is internally reflected. The percentage of light internally reflected, depends upon whether at least a front face of the encapsulant is immersed in liquid or in air. The optical liquid sensor also consists of a strategically placed photo sensor that detects the intensity of light that is internally reflected by at least the front face of the encapsulant surrounding the LED. The photo sensor is able to detect the change in intensity of light being internally reflected by at least the front face of the encapsulated LED when the front face, for example, emerges from immersion in a liquid.

A portable water filtration system that interconnects two, otherwise separate, water bottles arranged vertically such that water flows under gravitational pressure from a first water bottle through a filter configured to capture small particle impurities to a second water bottle and removes small particle impurities before they enter the second water bottle. The filtration system is implemented within a cap that can attach to a variety of standard water bottles, such as NALGENE&#x2122; water bottles. A removable connector ring attaches to the cap to connect a second water bottle to the system. When vertically aligned, water flows from a first water bottle through the filter element in the cap to the second water bottle to remove small and large particles.

Two bottle filter connector system with removeable ring

A portable water filtration system filters water as it flows through an inlet of a conventional storage container and removes impurities before they enter the container. The filtration system is implemented within a cap that can attach to a variety of standard water storage containers, such as Nalgene&#x2122;-type water bottles. When attached to the storage container, the cap seals around the container inlet and prevents the outer surface of the container inlet from contacting the water. To that end, two watertight seals are formed to isolate the outer surface of the inlet from any fluid communication, e.g., during a water-filling process. Because the outer surface of the inlet does not contact the unfiltered water, no contaminants can adhere to the inlet's surface and threaten a drinker's health if he/she drinks directly from the storage container after the cap is removed. The filtration system may be detachable from the base, such that the filtration system can be removed while the filtered water is disinfected using known ultra-violet (UV) and chemicals. In one embodiment, the filtration system may be cleaned and reinserted in an opposite orientation to seal the filtered and treated water in the container.

A hand-held water purification system includes an outwardly-extending pen-light sized configuration of solid state devices, such as, UV-light emitting diodes, that emit ultraviolet light in the germicidal range. The system operates to turn on the solid state devices under the control of one or more switches that are, in turn, under the control of a liquid-level sensor that senses when the configuration is immersed in the water. The system may also include a timing circuit that turns the solid state devices off a predetermined time after they are turned on. In one embodiment, a battery powers the various components of the system. In an alternative embodiment, the system power is provided by a base that plugs into a conventional power outlet. The base includes a converter that converts the signal provided through the power outlet to a signal that is appropriate to power the components.

Hand-held ultraviolet water purification system using solid state devices

A hand-held water purification system includes a pen-light sized ultraviolet lamp that is enclosed in a quartz cover and is powered by a battery and associated ballast circuitry. The battery and ballast circuitry are connected to the lamp by switches that are under the control of a liquid-level sensor. The sensor connects the battery, the ballast circuitry and the lamp once the sensor determines that the ultraviolet lamp is fully immersed in the water. If the container that holds the water is relatively large, the lamp and quartz cover end of the system are used to stir the water, to ensure that all of the water comes sufficiently close to the ultraviolet lamp.
