  • Publication number: 20220087853
    Abstract: A micturition device for fluid removal. The micturition device includes a micturition cup configured to encircle a user's urethra and vaginal anatomy and to facilitate evacuating a fluid from the micturition cup. The micturition cup is joined to a slide plate to form a common flow passage from the micturition cup through the slide plate. A garment, configured to be worn over a pelvic area, includes a slide track. The slide plate slidably engages with the slide track to allow a user to adjust a position of the micturition device relative to the user's vaginal anatomy in a seated or laying position and/or on the positioning of a seat. Also, a method of using the micturition device. Further, a micturition system for evacuating and receiving a fluid from the micturition device.

  • Publication number: 20210187425
    Abstract: An air filter device including an air filter unit and an expansion unit. The air filter unit includes a filter media assembly maintained by an outer frame assembly. The outer frame assembly defines exterior length, width and depth dimensions of the air filter device in an initial state. The expansion unit provides one or more of an expanded length, width or depth in an expanded state of the air filter device. Portions or an entirety of the expansion unit can provided apart from the air filter unit in a deliver condition of the air filter device, or can be assembled to the air filter unit prior to delivery to a user. The air filter devices of the present disclosure are useful with a wide variety of differently size air handling devices, able to readily seal with an air handling device compartment via the expansion unit.

  • Patent number: 10981099
    Abstract: An expandable air filter. The air filter including a filter media assembly, an outer frame assembly, and at least one support member. The filter media assembly defines opposing, first and second major faces and a perimeter. The outer frame assembly is arranged about the perimeter. The support member is connected to the outer frame assembly and extends across the first major face. Further, the support member defines a line of separation at which the support member can be separated into first and second segment to permit expansion of the air filter. The filter media can form a plurality of pleats, with at least one pleat being free of bonding to the outer frame assembly. The unbonded pleat experiences expansion as the air filter transitions to an expanded state. The air filter can be configured for expansion in one or both of a length and width direction.

  • Publication number: 20190046350
    Abstract: The present disclosure describes a system for providing targeted, temperature regulated therapy to a user. The system includes a convective unit and a forced air controller, with the convective unit including a sleeve for securing to a desired portion of the user's anatomy. The convective unit is fluidly coupled to the forced air controller, which is operable to transport a thermally conditioned air stream to an inflatable chamber in the sleeve. The convective unit receives the air stream, inflates, distributes the typically warmed, pressurized air within the inflatable chamber, and emits the air through one or more air permeable surfaces for convective transfer of heat to the body of the wearer enveloped by the sleeve.

  • Patent number: 10044203
    Abstract: A tablet storage device includes a module on a cart frame that includes a wheeled base. A cart module defines a selectively accessible interior space having multiple storage slots within the interior space for holding tablets. In some cases a tablet storage device holds multiple tablets using two or more modules in a stacked arrangement on a wheeled base. Each module can hold a portion of the multiple tablets within storage slots within an interior space inside the module. The storage slots may have connectors for connecting to tablets, and the cart frame can have a network connection system that is adapted to provide a network connection for each tablet that is connected to one of the connectors. The cart frame may also have a power supply system for charging each tablet that is connected to one of the connectors.

  • Patent number: 9967673
    Abstract: An acoustic transducer comprises one or more electromagnetic motors that drive one or more sets of multiple diaphragms to provide acoustically efficient loudspeaker systems having dimensions that allow use in applications that would be difficult or impossible with traditional transducers. The diaphragms may be driven directly, inertially or fluidically. If diaphragms are driven by rods that pass through holes in the diaphragms, noise may be generated by air that leaks through the pass-through holes. This noise may be reduced or eliminated by measures that reduce or eliminate the air leakage.
