  • Patent number: 11767839
    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.

  • Publication number: 20210393976
    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.

  • Patent number: 11103724
    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.

  • Patent number: 9885340
    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.
