  • Patent number: 12010960
    Abstract: The present invention relates to a reservoir cover for use with hydroponic, aeroponic, aquaponic or similar systems used to cultivate plant articles without soil medium. The reservoir cover containing and re-directing water, nutrients, and other liquids, intentionally or un-intentionally leaked by the system, back into a reservoir or water source the reservoir cover is positioned upon. Within hydroponic, aeroponic, aquaponic or similar systems the plant article is held within a plant growing unit positioned above the reservoir cover. As water is dispersed from within said systems gravity directs movement of water, nutrients, and other liquids to the reservoir cover of the present invention. As water, nutrients and other liquids are leaked or lost from the plant growing unit the reservoir cover is positioned such that water, nutrients and other liquids are not dispersed to an undesirable location, but rather are re-directed back in the original water source or reservoir.

  • Patent number: 12003512
    Abstract: According to an embodiment, a system comprises one or more processors and one or more computer-readable non-transitory storage media comprising instructions that, when executed by the one or more processors, cause one or more components of the system to perform operations. The operations comprise determining that an endpoint device has requested to discover a location of a protected resource that is protected by a gateway, determining whether the endpoint device has provided a token that is valid, and permitting the endpoint device to discover the location of the protected resource based on determining that the endpoint device has provided the token that is valid. The token indicates that the endpoint device successfully completed a first multi-factor authentication procedure in connection with accessing an authentication enforcement resource.

  • Patent number: 11956108
    Abstract: Apparatus and methods for sounding reference signal (SRS) switching are provided. In certain embodiments, a controller internal to the power amplifier module initiates a sequence of instructions, in response to a single command from UE. The instructions cause a reduction in RF signal amplitude at the power amplifier output and then cause the antenna switch to actuate. Thus ensuring a single command transition and preventing over-power on the power amplifier and antenna switch. The teachings herein can be used to facilitate reduction in gap times between transitions on different antennas and avoid the use of a blank symbol before and after each SRS symbol.
