Abstract: A hip thrust exercise guard comprising a pad, a bar insert in the pad to hold the bar of a barbell, and an adjustable band. The bar insert grips the bar of a barbell to prevent slippage during the hip thrust exercise, while still allowing slight side to side adjustments, in order to center the bar in the safest and most comfortable position. The attached adjustable band secures the pad around the hip in the optimal position for comfort, protection, and stability. The pad's soft foam construction and sculpted design contours to the hip area of the user.

Abstract: A nebulizer device aerosolizes (or vaporizes) liquid drawn from a liquid reservoir via a fluid flow path into a nebulization chamber. An inlet port is coupled to an external air supply and leads through a check valve and Venturi nozzle (e.g. a duckbill valve) into the chamber to direct an air stream across an opening of the fluid flow path. A discharge port leads from the chamber to a user mask, mouthpiece or canula, where the aerosol or vapor mixture can be inhaled. A filtered outlet port isolates exhaled material from the external environment. Multiple discrete heating elements may be placed around the fluid flow path to preheat the liquid. If the liquid is sufficiently volatile, heating may vaporize the material which can condense back into an aerosol after mixing with the air stream. A set of check valves direct one-way fluid flow and prevent leakage or spillage of material from the device.

Abstract: An EC motor for an electric hand tool having a stator in which a rotor is rotatably mounted, which comprises a rotor lamination stack, which has a passage opening and is formed of individual laminations, and a rotor shaft which is cast in the passage opening of the rotor lamination stack by means of a casting compound, and having a plurality of permanent magnets, which are received in the pockets formed in the rotor lamination stack. An annular channel, which is connected to the pockets in a fluid-conducting manner via radial channels, each of which is formed of a plurality of channel sections formed in adjacent laminations of the rotor lamination stack, is formed between the rotor shaft and the wall of the passage opening for supplying the casting compound from the annular channel to the pockets. A method is also provided for producing a rotor for an EC motor.

Abstract: A cartridge is inserted onto a nebulizer that aerosolizes (or vaporizes) liquid drawn from a cartridge reservoir via a flow path into a nebulization chamber. In such a nebulizer, an inlet port is coupled to an external air supply and leads through a Venturi nozzle into the chamber to direct an air stream across an opening of the flow path, while a discharge port leads from the chamber to a user mask, mouthpiece or cannula, where the aerosol or vapor mixture can be inhaled. A filtered outlet port isolates exhaled material from the external environment. Multiple discrete heating elements may be placed around the flow path to preheat the liquid. If the liquid is sufficiently volatile, heating may vaporize the material which can condense back into an aerosol after mixing with the air stream.
