Abstract: In one embodiment, a method, by an authentication server, includes generating a transaction identifier associated with an authentication request received from an external device. In response to verifying a first authentication factor of the authentication request, the method includes transmitting a prompt and the transaction identifier to the external device, wherein the prompt is an HTTP link associated with a browser comprising a generated cookie, the generated cookie being associated with the transaction identifier. The method includes receiving a signal comprising a transmitted transaction identifier and an instruction to process the HTTP link. The method includes instructing an application installed on the external device to open the browser in a webview in response to processing the instruction, wherein a cookie is provided. The method includes identifying the generated cookie based on verifying the transmitted transaction identifier.

Abstract: An air journal bearing for a rotatable shaft of a turbomachine includes a journal sleeve having an inner cylindrical surface and a central axis defining longitudinal and radial directions, a top foil disposed radially inboard of the journal sleeve and configured to receive the rotatable shaft, and a bump foil disposed between the top foil and the journal sleeve and configured to bias at least a portion of the top foil against an outer surface of the rotatable shaft. At least one of the bump foil and a radially extending segment of the top foil is formed contiguous with the inner cylindrical surface. The journal sleeve, the top foil and the bump foil may be formed as a single piece made of selectively sintered ceramic-metal powder.

Abstract: A filter dryer functions bypass system in a vapor cycle machine includes a refrigerant filter/dryer receiving a flow of liquid refrigerant from an inlet line and expelling the liquid refrigerant to an outlet line. A bypass line interconnects the inlet line and the outlet line and a bypass valve is configured to divert a portion or all of the flow of liquid refrigerant from the inlet line into the bypass line. A condition sensor provides a status signal indicative of refrigerant filter dryer condition and the bypass valve is operable responsive to the status signal.
