Abstract: A flashlight comprising a housing, a circuit board fixed in the housing and having opposite main surfaces with the circuit board oriented so that a first one of the main surfaces faces in a first direction and a second one of the main surfaces faces in a second, opposite direction, a light source disposed on the second main surface of the circuit board, an electrical contact mounted on the first main surface of the circuit board to be fixed in the housing, a battery having opposite first and second ends and having a first terminal at the first end thereof, and a conductive band electrically coupled to the circuit board and engaging the second end of the battery to bias the first terminal towards the electrical contact.

Abstract: Compact light devices are described herein that are advantageously configured to be secured to a surface in order to provide inexpensive lighting forwardly therefrom. The compact light devices can include on and off configurations in order to preserve battery life and allow a user to selectively energize the light source.

Abstract: There is provided hands-free lighting, components thereof, and other accessories combined with the hands-free lighting. The hands-free lighting is preferably lighted headgear including hats or visors or other headgear. The hands-free lighting may include multiple light sources positioned at the brim of a lighted hat and configured to provide beams of illumination along different axes thereby illuminating distances both near and far from the wearer at the same time while maintaining natural and streamlined appearance of the lighted hat.

Abstract: There is provided hands-free lighting, components thereof, and other accessories for being combined with the hands-free lighting. The hands-free lighting is preferably lighted headgear including hats and includes various accessories for use therewith, such as lighted headgear having two switch or actuator devices mounted thereto. The two switch devices can include a temporary switch device and a maintained switch device. The lighted headgear can further include a switch guard associated therewith. The lighted headgear can alternatively or also include a switch cover. The switch guard and/or the switch cover can be associated with packaging configured to mount to the lighted hat to substantially prevent inadvertent activation while still allowing intentional actuation thereof, or substantially prevent activation thereof, respectively.

Abstract: An illuminated eyeglass assembly includes one or more temple members having an integral lighting assembly structured and disposed to provide an illumination region proximate a user, for example, to illuminate an item within an arm's length of the user. Each integral light assembly includes at least one light source interconnected to a power source via a switch mechanism. Each of the light sources produce a light beam, and the light sources are structured and disposed such that the light beams provide an illumination region immediately proximate the user, thereby permitting the user to perceptively view an item in a low light environment, such as, to permit the user to read menu or a check in a restaurant or nightclub. A system is provided to retrofit an existing eyeglass assembly with one or more temple member having an integral lighting assembly.

Abstract: A system for the purification of contaminated water to produce potable water. The apparatus of the system may be mounted on a mobile platform for use in remote locations or may be sized and adapted for permanent installation. The process ozonates the contaminated water, while the water is maintained under substantially laminar flow conditions, in a series of vessels under countercurrent process flow conditions. The water is treated with sufficient ozone, and the apparatus provides a sufficient residence time, to oxidize pathogens and oxidizable matter. Residual ozone is substantially completely neutralized with ultraviolet radiation. Ozone off gas not dissolved in the water during ozonation is collected and any ozone in the gas is converted to oxygen to prevent ozone release into the atmosphere.

Abstract: An apparatus for the electrolytic treatment of liquid waste streams and a method for treating waste streams using the apparatus. The apparatus includes improved design to maximize the efficiency of electrolytic treatment of the waste stream.
