Abstract: The present system is directed in various embodiments to devices, systems and methods for detection, evaluation and/or monitoring olfactory dysfunction by measuring and determining the patient's olfactory detection threshold for the left and the right nostril. In some cases, the present invention relates to devices, systems and methods for detecting an asymmetric differential in a patient's relative olfactory detection and/or identification threshold (left vs right nostril) which, when present, may be used as a device to detect, diagnose and/or monitor olfactory deterioration resulting from Alzheimer's disease, and/or the efficacy of treatment regimens therefor over time. Alternatively, general olfactory dysfunction may be evaluated and/or monitored without regard to the individual nostril's performance.

Abstract: The present system is directed in various embodiments to devices, systems and methods for detection, evaluation and/or monitoring olfactory dysfunction by measuring and determining the patient's olfactory detection threshold for the left and the right nostril. More specifically, the present invention relates to devices, systems and methods for detecting an asymmetric differential in a patient's olfactory detection threshold (left vs right nostril) which, when present, may be used as a tool to screen, detect, diagnose and/or monitor relative olfactory deterioration resulting from Alzheimer's disease. A preferred embodiment comprises cascading aromas by serially administering more than one pure odorant to the patient's nostrils, left vs right, with measurement of the time, or numbers of breaths, required to cognitively notice the pure odorants' presence.

Abstract: The present method is directed to determining whether a living, non-demented patient with Alzheimer's neuropathology, i.e., significant levels of amyloid plaque in the brain, is within the early pre-clinical stages of Alzheimer's disease. In turn, if the living, non-demented patient with Alzheimer's neuropathology is determined to not be in the early stages of Alzheimer's disease, then it may be concluded that the patient has at least a resistance to Alzheimer's disease neuropathology, and perhaps an immunity thereto, wherein the amyloid plaque does not localize to the patient's brain synapses, thereby preserving cognitive ability. A 3-step method comprising (1) conducting a cognitive test; (2) detecting brain plaque levels; and (3) conducting a bi-lateral olfactory sensitivity test using pure odorants is therefore provided.

Abstract: The present system is directed in various embodiments to devices and methods for testing a patient's olfactory capability and/or sensitivity. The devices and methods may be used to test and compare a patient's ability to detect and/or identify an aroma or odorant presented to each nostril. Alternatively, the devices and methods may be used to generally assess, without regard to nostril-to-nostril comparative results, a patient's olfactory ability. The device may comprise a disk that comprises a plurality of odorant compartments that may be progressively advanced as the testing for a subject odorant is completed. The device may comprise a passive airway and an active airway, wherein only one nostril receives aroma-infused air while the other nostril receives atmospheric air. In other cases, the device may present aroma-infused air to both nostrils at the same time.

Abstract: A method of repurposing dual-paned insulated glass window units (IGUs) that would otherwise be put to waste into thermal solar panels capable of generating hot water for a residence or other structure. The method includes the steps of removing an existing IGU, disassembling and cleaning the IGU, and reassembling the IGU with a new silicon seal and fluid channels for connection to a looped solar heating system. The space between the panes may be filled with a liquid to be heated by solar radiation, or alternatively by a conduit which transports the liquid through the panel.

Abstract: A drywall tape and texture system for pumping fluid material from a container to a work surface includes a pump housing, a compressed air supply, a plurality of air release mechanisms, and an inflatable bladder mounted within the pump housing and held between upper and lower valves for controlling the flow of the material. The pump housing may be fully or partially immersed into a container filled with fluid material. An automatic pneumatic pressure relief valve automatically cycles open and closed whenever a control line is held closed by an operator. When the normally closed automatic air release mechanism is closed, the control line may also be closed by the operator, causing the bladder to inflate and pump fluid out of the pump housing. When the control line to the atmosphere is opened, the bladder deflates and a partial vacuum is created, thus refilling the pump through the lower valve.

Abstract: A drywall taping and texture system for pumping drywall mastic material from a container filled with the drywall mastic material to a work surface includes a pump housing, an air compressor, a tool for applying the drywall mastic material to the work surface, material and control lines, an inflatable bladder, an air release mechanism, and an airway. The pump housing is immersed in the container filled with the drywall mastic material, and the air compressor is connected to the pump housing. The material and control lines are connected between the pump housing and the tool such that there is material and air flow communication, respectively, therebetween. The bladder is mounted within the pump housing between upper and lower valves for controlling the flow of the drywall mastic material. The airway connects the air compressor, the control line, the bladder, and the air release mechanism, such that there is air flow communication therebetween.

Abstract: An inexpensive pneumatically-operated apparatus is disclosed for spraying a broad range of viscous materials that atomizes the sprayable material without using propellant gases, and can be filled with bulk texture or other fluid coatings. A container removably locks onto the bottom of a sealing disk, consisting of a dip tube, an elbow, an air jet member, an equalization port, and an equalization tube. A cap is selectively united with the sealing disk and the container. The user fills the container with the sprayable material, attaches it to the sealing disk and cap, and connects to an external air supply device. A spray nozzle is used to adjust the type of spray, and the user holds up the apparatus as one would hold an aerosol spray can.

Abstract: A portable drywall texture sprayer includes a generally cylindrical tank filled with fluid drywall material, a tool connected to the tank through a set of hoses or lines, and an air supply connected to the tank. The set of hoses or lines includes a material line and a control line. The material line is connected between the tank and the tool such that there is material flow communication therebetween. The control line is connected between the tank and the tool such that there is air flow communication therebetween. An air tube is mounted within the tank and connected to the control line such that there is air flow communication therebetween. An air duct connects the air tube and the air supply such that there is air flow communication therebetween. The sprayer also includes a control orifice on the tool for controlling the air pressure within the tank.

Abstract: A low cost stereo dispensing container (e.g. a disposable caulking cartridge) from which two part fluid products may be simultaneously dispensed in predetermined proportions relative to one another. A first material (e.g. a catalyst) is stored within a flexible blister. The blister may be adhesively affixed to a side of the container. In the alternative, the blister may be extruded or injection molded along a side of the container during manufacture. The second material (e.g. a resin) is stored within a holding chamber formed in the container alongside the blister. A plunger is moved through the container to ride over and compress the blister and thereby cause the first material to be expulsed therefrom into a spout of the container. At the same time, the volume of the holding chamber is reduced to thereby cause the second material to be simultaneously expulsed therefrom into the spout.
