Abstract: The present disclosure provides methods to improve the performance of heat exchangers used in thermoelectric cooling/heating devices, wherein improved heat conduction between heat exchanger and thermal exchange fluid is accomplished. Additionally, a method is disclosed to minimize the necessary delay used to protect the thermoelectric modules against thermal shock when switching from heat to cold, or vice versa. Thermal shock can damage thermoelectric modules when the direction of current passing through the modules is instantly switched.

Abstract: A battery pack configured to supply power to a cleaning system and be received by a battery receptacle of the cleaning system. The battery pack includes a housing including an aperture, a user contact moveable between a first position and a second position, a moveable member that moves from a retracted position to a protruded position when the user contact moves from the first position to the second position, and an engagement member that moves from a latched position to an unlatched position when the moveable member moves from the retracted position toward the protruded position. A portion of the moveable member extends through the aperture of the housing when the moveable member is in the protruded position to eject the battery back from the battery receptacle.

Abstract: A cordless, battery-powered system of cleaning products. The system of cleaning products includes devices such as upright vacuums (e.g., a stick vacuum, a lightweight upright vacuum, etc.), a hand-held vacuum, a carpet-cleaner, a canister vacuum, and the like. Each of the devices is powered by a battery pack which is interchangeable among the devices. The battery pack includes a combination of hardware and software for connecting to, identifying, and communicating with the cleaning products to ensure that each of the products receives the power necessary to ensure optimal performance.

Abstract: A vacuum cleaner includes a base having a foot and a handle assembly pivotally coupled to the foot, and a canister assembly removably supported by the base. The vacuum cleaner also includes a first engagement member extending from one of the base and the canister assembly. The first engagement member engages the other of the base and the canister assembly to support the canister assembly on the base and inhibit the canister assembly from sliding side-to-side relative to the base. The vacuum cleaner further includes a second engagement member supported by one of the base and the canister assembly. The second engagement member engages the other of the base and the canister assembly to inhibit movement of the canister assembly away from the handle assembly when the canister assembly is supported on the base by the first engagement member.

Abstract: A nasal dilator that includes an upper resilient member for dilating the nasal valve and a lower resilient member for dilating the nostrils. The upper resilient member and lower resilient member may be attached to one another by a flexible substrate having a middle portion that is narrower in length than the upper or lower resilient members. The nasal dilator also may have adhesive tabs extending downwardly from the lower portion of the substrate on either side of the nose and towards the nostril entry, for temporary attachment to the side of the nasal vestibule to reduce nostril collapse. The nasal dilator also may include bendable or configurable hooks extending downwardly from the lower portion of the substrate and towards the nostril entrance for insertion into the nostril to reduce nostril collapse.

Abstract: A personal security system is described herein that includes a mobile electronic device and associated cover. The cover comprises a housing that defines a recess, and an alarm system is disposed within the recess. The cover further includes a triggering mechanism external to the housing, the triggering mechanism being operable to actuate the alarm system in response to user interaction therewith. The alarm system is capable of generating an audible panic alarm in response to user actuation thereof. The alarm system is also capable of wirelessly communicating with the mobile electronic device itself to cause the mobile electronic device to perform additional functions that relate to personal safety when the panic alarm system has been actuated by a user thereof.

Abstract: An anatomically designed egg-shaped or elliptical-shaped nasopharyngeal airway for providing a comfortable and safe air passage through a nose to a nasopharynx includes a cannula having a proximal open end, a distal end, and a sidewall surrounding a lumen of the cannula. The nasopharyngeal airway has a port, which includes two or more openings separated by one or more bridges, in the sidewall, at a distal portion of the cannula. Upper and lower conduits may be located in channels of the sidewall of the cannula for delivery of oxygen and measurement of CO2 or other purposes.

Abstract: A nasopharyngeal airway for providing an air passage through a nose to a nasopharynx includes a cannula having a proximal open end, a distal closed end, and a sidewall surrounding a lumen of the cannula. The nasopharyngeal airway has an opening in the sidewall at a distal portion of the cannula for providing fluid communication between a distal portion of the lumen and the nasopharynx when the cannula is inserted into the nose and a conduit in the sidewall of the cannula, the conduit having an opening adjacent to the proximal open end of the cannula and a conduit opening in a distal portion of the cannula for providing fluid communication between the conduit and the distal portion of the lumen.

Abstract: A latching assembly for a removable battery package to an electrically powered cleaning device is provided along with the electrically powered cleaning device and the electrical combination with the battery charger. The latching assembly on the battery package comprises at least one moveable first engagement member, in movable cooperation with at least one rod which is in movable cooperation with a user contact. The first engagement member secures the removable battery package with another engagement member associated at least with the cleaning device. The first engagement member is located toward a side of a long end of the battery package opposite the end with the user contact Moving the user contact moves the member through the rod between an engaged position to thereby secure the battery package to the cleaning device and an unengaged position for removal of the battery package from the cleaning device.

Abstract: A thermal therapy device (100) comprises a tissue-interacting device (400) which is designed to target one or more significant areas of the therapy-receiving person's body by concentrating the passage of the therapy-providing fluid in these areas. The thermal therapy device (400) can comprise a head pad, eye pads, a knee pad, an ankle/foot pad, an elbow pad, or a neck/shoulder pad.

Abstract: An eye-covering assembly (10) comprises a film layer (20) and a rim layer (30) having an inner surface (32) which adheres to the skin of the user's face. The inner and outer surfaces of the film/rim layers (20/30) are planar and parallel when the eye-covering assembly is in a pre-use relaxed state. The inner and outer surfaces of the film/rim layers (20/30) are curved and the rim layer (30) is compressed in certain regions, when the eye-covering assembly is in an in-use conforming state whereat it conforms to the contour of an eye-surrounding portion of a user's face.
