Abstract: A client application requesting to access a resource may be issued an access token and a refresh token. Instead of revoking the client application access to a resource by revoking the refresh token, allowing the access token to expire, and forcing a user associated with the client application to re-login, authentication for the client application to access the resource may be obtained from the user. The authentication may be obtained from the user while the client application, without notification of the concurrent authentication, may continue attempts to access the resource, for example, via an invalid access token. Once authentication is obtained, the client application may be provided access to the resource, for example, via a valid access token.

Abstract: Recovery of hydrocarbons, such as petroleum products, from a liquid or solid substrate is facilitated by the use of microwave energy to energize and separate molecular bonds between the hydrocarbons and the substrate. A radio frequency (RF) applicator delivers microwave energy to a treatment volume containing an emulsion of a hydrocarbon and a substrate. Delivering the microwave energy to the emulsion facilitates separation of the hydrocarbon and substrate molecules into layers. Hydrocarbons and other products can then be recovered from their respective layers. The treatment volume may be located either above or below ground. The RF applicator may include an antenna body with slots formed substantially parallel to one another in a substantially horizontal orientation. The RF applicator efficiently delivers microwave energy into the treatment volume. Substantially all of the power supplied to the RF applicator is radiated, with very little power reflected internally within the RF applicator.
