  • Publication number: 20170138562
    Abstract: The present disclosure s directed to an illumination and networking systems. The illumination and networking systems can include one or more light emitting devices and/or network devices. An illumination and networking component can be operably coupled to at least one of the one or more light emitting devices and the one or more network devices. The illumination and networking systems can include one or more access nodes, bridges, gateways, hubs, range extenders, repeaters, routers, or switches and can include a plurality of solid-state light emitters, circuitry configured to communicate one or more control commands for operating the one or more light emitting devices, and network devices. The illumination and networking system can manage power consumption and/or manage heat generation.

  • Patent number: 4236686
    Abstract: Manned or remotely piloted Vertical Takeoff and Landing (VTOL) aircraft is launched or retrieved from a capture drogue carried by an articulated boom. The capture drogue is stabilized in space for retrieval and launch and moves the aircraft to a platform while the drogue-aircraft are stabilized with respect to the platform.

  • Patent number: 4234346
    Abstract: A paving composition formed of aggregate mixed with substantially unblown asphalt cement (neither emulsified nor cut-back) including a soluble organic-manganese compound either alone or in combination with organic-cobalt or organic-copper compounds for improved strength. The composition is employed for paving roads by conventional techniques.

  • Patent number: 4107112
    Abstract: A method of stabilizing soil, such as sub-bases, bases and wear courses of roads and airport runways, sand dunes and other loose, particulate material, which includes mixing an epoxy resin ester of unsaturated fatty acids with soil, preferably at the optimum moisture content of the soil, in ratios of as little as one part of chemical to 200 parts of soil, with the amount depending on the use. Optionally, small but effective quantities of cement may be added to the composition in the range of about 2 to 20% of the weight of the soil. A soil coating or top dressing may be applied to the resultant structure if desired.
