Abstract: The disclosure relates to water treatment systems that may be used to remove impurities from water, particularly systems that inserted at the point of entry of a water supply into a building.

Abstract: The disclosure relates to pumping systems that may be used to pump fluids in variety of situations where it is important to maintain fluid flow. The systems include at least two pump assemblies. At least one controller, an inlet, an outlet, and a stand.

Abstract: The disclosure relates to a water treatment system which may include at least one reverse osmosis cartridge, at least one filtration cartridge, at least one pump and an enclosure.

Abstract: The disclosure relates to portable collector with solar panels where the collector may be reversibly rearranged to expose the solar panels to light.

Abstract: A radio access network (RAN) may be providing, in a coverage area, at least two access channels that are available for use by any wireless communication devices (WCD). Thereafter, the RAN may detect that a threshold load exists in the coverage area and responsively reserve one of the access channels for use only by authorized WCDs. In turn, authorized WCDs in the coverage area may be configured to use the reserved access channel to transmit access probes to the RAN, while unauthorized WCDs in the coverage area may be configured to use only a generally-available access channel to transmit access probes to the RAN. In this way, the disclosed methods and corresponding devices may limit the occupancy on the reserved access channel and thereby increase the likelihood that authorized WCDs can successfully access the RAN over the reserved access channel when the coverage area becomes congested.
