Abstract: A vacuum pump includes a hollow container that has a vacuum port and internal chamber walls. The vacuum port opens to an exterior of the container and the chamber walls define chambers that are in fluid communication with the vacuum port. There are flexible bladders disposed in the chambers. The flexible bladders include vents that open through the container to the exterior. A plunger in the container includes arms that extend into the chambers such that each of the flexible bladders is situated between one of the arms and one of the chamber walls. The plunger is moveable between a home position and an upstroke position to compress and deflate the flexible bladders via the vents and thereby change the volume of the flexible bladders. The change in the volume draws a vacuum through the vacuum port.

Abstract: A ring has an open top side and side walls that circumscribe a central region for receiving a phototherapy subject. The side walls include a work surface that is configured to receive visible light through the open top side and reflect the visible light toward the central region for phototherapy. The work surface includes a first surface that is a diffuse reflector and a second surface that is a specular reflector.

Abstract: A position-assisting device for milk expression includes an upright body wedge pillow that defines a back side that has an armrest, a front user-engagement side that is sloped back, lateral sides, and a bottom side. The upright body wedge pillow has an upper head-rest section and an interior cavity that has a front face that opens to the front user-engagement side so as to be able to receive a woman's breasts for milk expression. There are breast pumps located in the interior cavity for milk expression.

Abstract: A phototherapy device includes at least one flexible sheet that has first and second electrical conduction layers, an electrical insulation layer between the first and second electrical conduction layers, and light emitting diodes (LEDs) disposed along the electrical insulation layer between the first and second electrical conduction layers. The first electrical conduction layer includes a conductive polymer. The electrical conduction layers and the LEDs are part of an electrical circuit in which the LEDs illuminate responsive to an electrical input. There is at least one meter to measure an electrical property of the electrical circuit. A control module is in communication with the meter and configured to adjust the electrical input responsive to the electrical property of the electrical circuit.

Abstract: A photo-treatment device includes a non-opaque treatment substrate and a radiation-collector beside the substrate. The substrate is sized for a person at which radiation is to be emitted from above the substrate. The substrate has a front surface for receiving the person thereon and a back surface. The radiation-collector captures excess radiation peripheral to the substrate and redirects the excess radiation to the back surface of the substrate.

Abstract: A photo-treatment device includes a treatment region that has a front side at which source radiation is to be emitted and an opposite, back side. A plurality of light guides are located beside the treatment region. The light guides capture excess radiation peripheral to the treatment region and redirect the excess radiation toward the back side of the treatment region.

Abstract: A wound therapy system according to an example of the present disclosure includes a wound therapy that has a porous body operable to carry a fluid from a wound site, a tube, and a pump connected to the porous body by the tube. The pump is operable to apply vacuum through the tube to draw fluid from the wound site.

Abstract: A screened wind power generation system for generating power in locations where the sight of wind turbines is undesirable or where advertising space can be utilized. The system uses a screen to cover wind turbines with a mesh size and other characteristics that are appropriate for allowing sufficient wind to pass through to wind turbines. The mesh can be coated or imprinted with surface indicia that constitute advertising or create an appearance that blends with surroundings better than an unscreened wind power generation system. The depth of the screen can vary to better enable muffling of wind turbine noise. The screen cross-section can have an aerodynamic shape to facilitate wind flow through the screen.

Abstract: A solar panel assembly according to an example of the present disclosure includes a light-permeable panel, an opaque or solid region on the panel that at least partially blocks light from penetration through the panel, at least one solar array adjacent the panel, and at least one mirror situated such that at least some light permeating through the panel reflects off of the at least one mirror and onto the at least one solar array.

Abstract: A quick-connect coupling assembly, and method of making same, for connecting a fuel fill pipe to a fuel tank made of a polyethylene based material. A mounting bracket subassembly has a base molded of such tank-type material that is plastic welded to the tank fill opening margin. A second more stable plastic material also is used in the bracket not only to anchor the connection between the fuel tank and the fill pipe and to provide the necessary resistance to pull force against disconnection, but also to contain the polyethylene bracket material in such a way as to minimize geometric (dimensional) changes due to fuel absorption and creep in the critical region of the connection that contains the O-ring seals or like sealing elements.
