Abstract: A device for controllably releasing a fluid into an ambient environment. According to a particular embodiment of the present invention, the device comprises a housing having a fluid compartment and an orifice compartment disposed adjacent thereto and in fluid communication therewith via an orifice. The fluid compartment contains the fluid for release to the ambient environment. The orifice compartment includes a fluid exit opening covered by a removable sealing element and contains an initial quantity of fluid when the device is in an inactivated state. A fluid restrictor is disposed adjacent the orifice to restrict fluid flow from the fluid compartment into the orifice compartment in the inactivated state. A gas-generating cell is in selective communication with the fluid compartment such that gas generated by the cell is directed into the fluid compartment when the device is in an activated state.

Abstract: The present invention is directed to an apparatus and method for controllably adjusting a fluid delivery device. The device includes an electrochemical pump capable of transporting a fluid. A displaceable member is positioned between a pump product chamber and a reservoir, wherein the pump product chamber is capable of retaining water generated from the pump. The displaceable member is controllably displaced upon generation of water from the electrochemical pump and the reservoir contains the fluid that is delivered upon displacement of the displaceable member.

Abstract: The invention described herein is a framed fluid delivery device that is made up of a fluid-delivery cartridge for the timed-release delivery of a fluid contained therein, and a frame assembly for retaining the fluid delivery cartridge. The frame assembly is made up of a base portion that facilitates the delivery of fluid released from the fluid-delivery cartridge, at least one side panel associated with the base, and that secures the fluid-delivery cartridge within the frame assembly proximate the released fluid delivering means. Additionally, a fluid delivery device is disclosed that includes a fluid-delivery cartridge for the timed-release delivery of a fluid contained therein, the cartridge having a bottom, a top, and sides, and a dispersion pad positioned proximate the bottom of the fluid-delivery cartridge, wherein the dispersion pad at least partially surrounds the sides of the fluid-delivery cartridge.

Abstract: The present invention is directed to a device for releasing a fluid. The device includes a housing having an interior region, a fluid contained within the interior region, and the ability to controllably release the fluid from the housing.

Abstract: An electro-osmotic cell capable of substantially reducing zero-current transport is disclosed, wherein the cell includes a cell housing having a first half cell and a second half cell, with an ion selective membrane therebetween, a first electrode positioned within the first half cell, a second electrode positioned within the second half cell, an electrolyte in electrical communication with the first electrode and the second electrode, and a wiring apparatus electrically connecting the first electrode and the second electrode, wherein the wiring apparatus has one or more structures used for counteracting salt concentration increases within the electro-osmotic cell.

Abstract: A controlled sustained release fluid delivery device is disclosed which has enhanced fluid delivery. The device generally includes a housing having a fluid reservoir therein for holding a fluid, at least one opening in the housing for enabling fluid delivery out of the fluid reservoir and the housing, and structures for delivering the fluid, and retaining the fluid proximate an ambient environment. Once held there, the structure holding the fluid is vibrated so as to enhance the delivery of the fluid to the ambient environment. Other aspects are also disclosed.

Abstract: A storage stable hydrogen cell comprising an anode cap subassembly, cathode can subassembly, and a grommet is disclosed. For one embodiment the cathode in the cathode can subassembly is configured for contact with the electrolyte. The cathode is hydrogen permeable and substantially impermeable to O2, CO2 and water. In turn, the cathode can preclude the passage of O2, CO2 and water into and out of the cell, and simultaneously can facilitate the permeation of hydrogen through at least one aperture in the cell. In another embodiment, a commercially available Zn-air cell is converted into storage stable H2 cells by sealing a membrane structure around the apertures of the Zn-air cell. Such membrane precludes the passage of O2, CO2 and water into and out of cell but allows the passage of hydrogen generated in the cell through the aperture of the cell and through the membrane.

Abstract: A fluid delivery device comprising a chamber or electrode, wherein the chamber or electrode is capable of containing a chemical and/or electrochemical reagent which expands upon a chemical reaction of the same. The expansion, in turn, displaces a displaceable member which facilitates delivery of fluid from an associated reservoir.

Abstract: A fluid delivery device generally including: an electrochemical pump, wherein the electrochemical pump is capable of generating water; an electrochemical pump product chamber, wherein the electrochemical pump product chamber is capable of retaining water generated from the electrochemical pump; a displaceable member positioned between the electrochemical pump product chamber and a reservoir, wherein the displaceable member is controllably displaced upon generation of water from the electrical pump; a reservoir, wherein the reservoir is capable of containing a fluid which is delivered upon displacement of the displaceable member; and a housing for containing the electrochemical pump, the electrochemical pump product chamber, the displaceable member, and the reservoir.

Abstract: A brush having a handle and associated surface application portion, which brush handle contains a beneficial agent generator. The brush typically has a stem with first and second ends, the first end serving as a handle. Bristles are associated with the stem's second end. A beneficial agent generator (such as an electrochemical gas generating cell) that generates a fluid comprising an oxidizing agent is encased within the stem. For treating teeth, the generator will generally be chosen to generate an oxidizing agent such as a peroxide, ozone, oxygen, or mixtures thereof. When the generator requires it, the brush will also include a battery and a switch associated with the stem and in electrical contact with the generator. The switch may be associated with the first stem end and will be in operable (e.g., electrical) contact with the electrochemical gas generating cell and the battery.
