Abstract: A biofilm inhibition system, for a sensor which includes a chamber with an interior volume and an interior surface exposed to direct contact with a fluid during sensor operation, includes an ultraviolet light emitting diode (UV-LED) and an optical subsystem. The optical subsystem is coupled to the UV-LED to deliver a portion of the emitted UV light to illuminate a substantial fraction of the interior volume and the interior surface. A watertight housing encloses the UV-LED and at least a portion of the optical subsystem.

Abstract: A portable water purification device comprises a portable power supply, an ultraviolet light source coupled to the portable power supply, wherein the ultraviolet light source is configured to output ultraviolet light, a container coupled to the ultraviolet light source, wherein the container is configured to hold water, and wherein the container is configured to reflect ultraviolet light, and an indicator configured to output a visual indication when the ultraviolet light source is outputting ultraviolet light.

Abstract: A lighting fixture includes a main arm and a cantilever that is attached to main arm. The cantilever has mounted at one end a lamp and at the other end a weight. The cantilever is mounted to the main arm. The weight is attached to the cantilever in such a way as to allow the cantilever to rotate so at to cause to the lamp to move from one position to another position.

Abstract: Electronic devices involving contact structures, and related components, systems and methods associated therewith are described. Contact structures (also referred to as electrical contact structures or electrodes) are features on a device that are electrically connected to a power source. The power source can provide current to the device via the contact structures. The contact structures can be designed to improve current distribution in electronic devices. For example, the contact resistance of the contacts may be modified to improve current distribution (e.g., by controlling the shape and/or structure and/or composition of the contacts). The contact structures may include an intervening layer (e.g., a non-ohmic layer) positioned between a surface of the device and a conductive portion extending from a conductive pad. The intervening layer and/or conductive portions may be designed to have certain shapes (e.g.
