Abstract: An oxygen concentrator may rely on a pressure swing adsorption process to produce an oxygen enriched gas stream from canisters filled with granules capable of separation of oxygen from an air stream. The adsorption process uses a cyclical pressurization and venting of the canisters to generate an oxygen enriched gas stream. Coupling an oxygen concentration sensor to the generated oxygen enriched gas stream may allow monitoring of the purity of the produced gas.

Abstract: The present invention relates to a modular electrode system, and its use, for facilitating the introduction of a macromolecule into cells of a selected tissue in a body or plant. The modular electrode system comprises a non-symmetrically arranged plurality of needle electrodes; a hypodermic needle; an electrical connector that provides a conductive link from a programmable constant-current pulse controller to the plurality of needle electrodes; and a power source. In a preferred embodiment of the present invention, an operator can grasp the plurality of needle electrodes that are mounted on a support structure and firmly insert the them into the selected tissue in a body or plant. The macromolecules are then delivered via the hypodermic needle into the selected tissue. The programmable constant-current pulse controller is activated and constant-current electrical pulse is applied to the plurality of needle electrodes.

Abstract: In some embodiments, an oxygen concentrator may include lightweight injection molded housing components coupled to dual-pump diaphragm compressors. The oxygen concentrator may be coupled to a pressure transducer that detects a user's inhalation. The detected inhalation may signal the release of a bolus of oxygen. The sensitivity of the pressure transducer readings may be adjusted based on a detected environment. The user's breathing rate may also be determined to control the number of compressors used for increased efficiency. An ultrasonic sensor and gas flow rate meter may be used to determine an amount of oxygen being delivered to the user. Other components such as step valves and a solar panel may also be used to further conserve battery power. The oxygen concentrator may also incorporate an audio device such as a mobile phone.

Abstract: The present invention relates generally to the field of illuminated articles including, but not limited to, illuminated intimate apparel. In practicing an embodiment of the present invention, one may weave, embroider, or by other means attach optical fibers to lingerie to form geometric patterns that are aesthetically pleasing. In a preferred embodiment, a portion of one or more optical fibers are interwoven or connected by other means to an article of intimate apparel. A first end of the each fiber may be connected directly to an article and/or connected along an article and bent so as to emit light at selected points. The opposite end of each optical fiber is permanently or removably connected to a light emitting diode (“LED”) or other suitable light source to provide light energy through the optical fiber.

Abstract: A screen cleaning and utensil container shaped to simulate a consumer product package is provided. The screen cleaning and utensil container includes a body having a sidewall, bottom wall and a top wall shaped to simulate a consumer product having an exterior surface, the body forming at least one internal compartment adapted for storing utensils, the top wall forming a top opening in connection with the internal compartment and at least one cleaning member for cleaning a display screen is connected to a portion of the surface.

Abstract: Energized body jewelry including alternative embodiments designed to be worn by persons who have piercings in their bodies, as well as for those who do not have piercings. In one embodiment, the jewelry may be worn by a person with a piercing by attaching the jewelry with a barbell style piercing including a slotted or drilled retainer sized to carry the jewelry. In an alternative embodiment, through the use of an elastomeric band attachment means, or a drilled elastomeric band, the jewelry may be worn by a person who does not have a piercing. The jewelry is energized such that it may vibrate, illuminate, or perform other functions requiring energy from some extracorporeal source such as a battery.

In one embodiment, the jewelry may be worn by a person with a piercing by attaching the jewelry with a barbell style piercing including a slotted retainer sized to carry the jewelry. In that same embodiment, the jewelry alternatively, through the use of an elastomeric band attachment means, may be worn by a person who does not have a piercing. The jewelry is energized such that it may vibrate, illuminate, or perform other functions requiring energy from some extracorporeal source such as a battery.

Abstract: A flow through cell for non-invasive monitoring of fluids flowing therethrough includes a membrane covered view window through which sensors may monitor the fluids. The membranes are secured in position by a frame and retainer assembly with the frame and retainer clamping the membranes in place between the frame support structure and the retainer. The frame is snugly fitted into the cell and includes a sensor receptive chamber for positioning the sensors in the window and in position with the membranes.

Abstract: A combination medication mold and dispenser. The medication is poured into a multicompartment tray and solidifies into troches. The tray is made of a flexible plastic which can be bent to release the troches individually. The tray has a cover attached with a flexible hinge to protect the troches after preparation. The medication can be prepared and dispensed to the patient in the same container. The covered tray can be held in a sleeve to further protect the medication and hold the cover in place.

Abstract: A combination mold and carrier for seamless suppositories. The dispenser has an elongated rectangular one-piece body of a flexible material that is dimensionally stable at ordinary temperatures. A plurality of suppository cavities of uniform constant tapers with rounded bottoms are formed in tubular members extending from the top side of the body. The body side surfaces are tapered with circular cross sections concentrically with the cavities. These side surfaces merge together adjacent the topside and separate into the individual tubular members towards the bottoms of the cavities. The cavities have rounded bottoms to facilitate ejection of suppositories by a manual pinching action. A circular flat base formed on the rounded walls support the body upright on a work surface with the cavities upright to receive a suppository mixture. A rectangular cover with open ends can be slideably mounted over the body in a telescoped relationship.

Abstract: A blood and perfusate filter apparatus having a pair of molded housing members that are substantially identical in their configuration. The upper housing member having a pyramidal-shaped reservoir formed in the upper surface thereof which acts as a secondary distribution reservoir, and the lower housing member having a pyramidal-shaped reservoir formed in the lower surface thereof which acts as a secondary collection reservoir. Interchangeable tubing couplings are press-fit bonded to inlet/outlet ports located in the secondary reservoirs. A filter element, mounted in a resinous band, is bonded between the housing members so as to filter blood or perfusate as it passes through the filter. The filter element also forms primary distribution and collection reservoirs with respect to the upper and lower housing members. Different types of filter configurations, such as flat or pleated, can be mounted in a resinous band and used as the filter media.
