  • Patent number: 11332777
    Abstract: Disclosed herein are methods, reagent kits, and compositions for performing a bisulfite conversion of DNA directly from a biological sample including a patient's urine sample or a slide-mounted FFPE tissue sample. For example, a method of performing a bisulfite conversion of DNA can comprise certain preliminary steps for processing the biological sample and transferring a portion of the processed sample into a reaction vessel containing a bisulfite mixture. The method can further comprise heating the reaction vessel containing the biological sample and the bisulfite mixture at several heating temperatures and subsequently holding the reaction vessel at a holding temperature for a holding period. The method can also comprise certain bisulfite removal steps, desulfonation steps, and removal of the desulfonation solution. A final elution step can yield the converted DNA for further downstream sequencing and analysis.

  • Publication number: 20220110089
    Abstract: Systems and methods of the present disclosure provide techniques to locate target devices. An electronic message is sent to a set of landmark devices, signaling each landmark device to transmit echo-request packets to a target device and to other landmark devices and measure network-communication delays. Indications of the network-communication delays are received from the set landmark devices. A first sequence is formed by sorting the set of landmark devices relative to the network-communication delays between the target device and each landmark device. For each respective landmark device, an additional sequence is formed by sorting other landmark devices relative to the network-communication delays between the respective landmark device and the other landmark devices. A sequence-matching operation is applied to the first sequence and the additional sequences to form a ranking of the set of landmark devices relative to the target device.

  • Patent number: 11229001
    Abstract: Systems and methods of the present disclosure provide a way to pinpoint where a target device associated with an IP address is physically located within a geographical region. Network-communication delays between landmark devices and the target device are determined and used to generate sequences capturing relative delay relationships between the landmark devices and the target device. The sequences are used to determine a ranking via a sequence-matching approach. For each pair of landmark devices, a geographical boundary that divides the geographical region into a target partition and a second partition is determined. The target partition includes a first landmark device of the pair and the second partition includes a second landmark device of the pair. The target device is located where the target partitions for the pairs overlap. Network tomography can be applied to increase accuracy.
