20090279050ELECTRO-OPTIC LENSES FOR CORRECTION OF HIGHER ORDER ABERRATIONS - A lens is presented in which the lens includes a substrate and an electrode layer. The electrode layer is positioned upon the substrate. The electrode layer has radially alternating rings of electrodes and resistive material. When voltage is applied across two adjacent electrodes the profile of the electric field therebetween is linear. When voltage is applied to the rings of electrodes, the optical phase profile of the lens closely approximates the optical phase of ideal spherical aberration correction.11-12-2009

Patent application numberDescriptionPublished
20090008411WEARABLE CHEMCIAL DISPENSER - Disclosed herein are wearable devices for dispensing insect repellents, fragrances, and/or other chemicals along the outside of the clothing of a human, to avoid the need to apply such chemicals directly to clothing or to human's skin. The devices have an on/off switch that automatically controls a shutter which enables and restricts air flow, while also controlling fan operation and covering of a use-up cue. The device also is designed to prevent fan operation when an impregnated slab is not present. Also disclosed are preferred refills for use with such devices.01-08-2009
20100147972Breakable Wick for Use in a Dispenser for a Volatile Liquid - A wick assembly for use in a dispenser for a volatile liquid includes a wick having an external surface and a discontinuity in the surface providing a location in the wick of less resistance to a force applied to the wick than a location adjacent to the discontinuity. In one embodiment, the wick is adapted to be positioned to extend from an inside of a container, through an opening defined in the container, to an outside of the container, and the wick is formed such that a portion of the wick will block the opening when the wick is broken at the discontinuity.06-17-2010
