Abstract: Rotary steerable drilling systems are subjected to harsh environments including high temperature and pressure. A metallic seal ring prevents or limits erosive wear by limiting the velocity of the fluid that traversers from the high pressure side of the metallic seal ring to the low pressure side of the metallic seal ring to a value that can be sustained by the material of the metallic seal ring. A metallic seal ring is capable of withstand the wear and tear of drilling mud or other fluids used for downhole drilling operations. A metallic seal ring includes a mating configuration that creates a seal as the metallic seal ring is contracted when or a tension is applied when disposed or positioned in the piston bore. The metallic seal ring maintains an adequate seal to protect the components of a pad assembly over the life or specified duration of a downhole drilling operation.

Abstract: Systems and methods for securing user location data are described. A method includes receiving, by a location server computer, an encrypted location from a mobile device. The encrypted location is a location of the mobile device encrypted with a public key. The method then includes receiving, by the location server computer, a location request message from an interaction processing server and partially decrypting, by the location server computer, the encrypted location with a first private key share to form a partially decrypted location. The method further includes transmitting, by the location server computer to the interaction processing server, a location response message with the encrypted location and the partially decrypted location. The interaction processing server then uses the partially decrypted location and the second private key share to form a decrypted location.
