  • Patent number: 10928405
    Abstract: Some embodiments of the present invention generally relate to devices and methods for determining and/or isolating cells. For example, one aspect is generally directed to methods and devices for detecting, identifying, counting, and/or potentially sorting cells of interest in blood or other biological sample. In some embodiments, blood samples (or other biological fluids) may be treated with signaling entities, such as pH-sensitive entities, that change color or otherwise produce a signal in suitable internal environments. For example, certain cells, such as cancer or fetal cells, may have differences in intracellular pH compared to other cells, which can be detected using pH-sensitive entities. In certain embodiments, the cells may be sorted based on such signaling entities; for example, illumination of cells in a suitable machine for sorting cells (e.g., using fluorescent light) may allow determination of the cells, which may also be recovered or isolated for further manipulation in some cases.

  • Patent number: 10834066
    Abstract: A method and system for authenticating answers to Domain Name System (DNS) queries originating from recursive DNS servers provided. A verification component provides a versification that a DNS query originated from the recursive DNS server. An authoritative DNS server receives the query via a network, such as the Internet, provides an answer to the query to an authentication component. The authentication component then provides an authentication such as a digital signature, which confirms that the received answer was provided by the authoritative DNS server, and then communicates the answer and the authentication to the verification component via the network. The verification component then verifies that the authentication corresponds to the receive answer and sends the answer to the recursive DNS server. When the verification component receives an answer in the absence of a corresponding authentication the verification component drops the answer.

  • Publication number: 20200332203
    Abstract: A process is presented to treat a process stream containing a hydrocarbon (oil and/or gas) and hydrogen sulfide with a liquid treatment solution containing a sulfur dye catalyst. The process stream can be within a pipeline, wellbore, subsea pipeline or a wellhead that contains hydrogen sulfide where the liquid treatment solution is injected at a predetermined point to define a scavenger zone such that the sulfur dye catalyst in the liquid treatment solution causes the sulfide from the hydrogen sulfide to react with the catalyst. The hydrocarbon component is separated substantially free of the hydrogen sulfide from a spent treatment solution containing spent sulfur dye catalyst which can then be fed to an oxidation vessel where it is contacted with an oxygen containing gas causing the sulfide to oxidize to thiosulfate and converting the spent sulfur dye catalyst to regenerated sulfur dye catalyst.
