Abstract: Example implementations relate to the processing of refresh token requests at an API gateway. The API gateway determines a first time associated with receipt of the refresh token request and a second time associated with the generation of a current access token. The current access token and a refresh token in the refresh token request are provided by the API gateway to the client device for accessing a backend service. The API gateway determines whether a difference between the first time and the second time is within a pre-defined threshold duration. When the difference between the first time and the second time is within the pre-defined threshold, the API gateway denies the refresh token request for generating the new access token and transmits the current access token back to the client device.

Abstract: A marine autopilot system configured to control a marine vessel through a marine environment is disclosed herein. The marine autopilot system may obtain data of the marine environment from charts and community shared data and generate a path from a first location to a destination location in the marine environment. The marine autopilot system may control the marine vessel along the path based on the marine vessel dynamics and weather and water current conditions. Sensors may detect hazards on and in the water and object detections systems may classify the hazards. The marine autopilot system may control the marine vessel to avoid the hazards based on the location and classification of the hazards. Furthermore, sensors may be utilized to generate detailed 3D maps that change with time to dock the marine vessel at known and unknown locations.

Abstract: A multi-level rotor for a coolant flow control valve assembly, which accommodates an increased number of inlet ports, outlet ports, and flow channels using a single rotor located in a housing, enabling a larger number of flow configurations. The housing includes nine ports which may function as an inlet or an outlet, which facilitates different flow configurations. For a thermal management system, reduced cost and less space utilization is achieved by a reduced number of valves, where the multi-level rotor is able to fluidically connect multiple inlets/outlets. This enables different flow configurations, depending on the degree of rotation. The channels at different levels are sealed from each other within the housing. The flow channels are manufactured into a single entity, therefore always having the same positional accuracy relative to each other when the rotor is repositioned.

Abstract: An vapor purge system for a turbocharged internal combustion engine having an evaporative emissions turbo purge valve incorporating a venturi vacuum generator and a hose-off detection function. The turbo purge valve includes a pressure sensor, and a low restriction check valve which is integrated into the outlet port of the venturi vacuum generator. The pressure sensor is capable of detecting the small pressure drop (i.e., vacuum) generated at the air inlet tube or air box during naturally aspirated conditions. The check valve closes the venturi vacuum generator on the purge side during naturally aspirated conditions, allowing fluid communication to the air intake system through one port only, and the detection of the vacuum during these conditions. If a hose becomes detached, either at the outlet port of the venturi vacuum generator or at the air box, the small vacuum is not detected, and the ECU then diagnoses the hose-off condition.

Abstract: An electronic compressor bypass valve (eCBV) includes a housing having an annular internal surface defining an opening therein. A piston-seal structure is constructed and arranged to be movable linearly within the opening. The piston-seal structure includes a generally cylindrical piston portion having proximal and distal ends. The distal end defines a seal surface constructed and arranged to seal with a body. The proximal end defines a first outer diameter. The piston-seal structure further includes an annular seal portion fixed to the proximal end of the piston portion. The seal portion has an outer diameter that is larger than the first outer diameter of the piston portion, thereby defining an annular sealing surface. Upon movement of the piston-seal structure, the sealing surface is constructed and arranged to slidingly engage the annular internal surface of the housing thereby creating an annular seal between the piston portion and the housing.

Abstract: An electronic compressor bypass valve (eCBV) module includes a pedestal housing, and a compressor bypass valve mounted to the pedestal housing. An inlet port, a first outlet port, and a second outlet port are integrally formed as part of the pedestal housing, where pressurized air flows into the inlet port. The eCBV module also includes a venturi device at least partially disposed in the second outlet port. When the compressor bypass valve is in an open position, a portion of the pressurized air flows through the first outlet port, and a portion of the pressurized air flows from the inlet port through the venturi device and through the second outlet port. When the compressor bypass valve is in the closed position the pressurized air is prevented from flowing into the first outlet port, and all of the pressurized air flows through the venturi device and through the second outlet port.

Abstract: A three-port turbo purge module, including a housing having a cavity, and two check valves. During a first mode of operation, the first check valve is open and the second check valve is closed by vacuum pressure generated in an intake manifold, such that purge vapor flows from an inlet port into the cavity, through the first check valve, and into a first port. During a second mode of operation, where the intake manifold is operating under positive pressure, the first check valve is closed such that pressurized air flowing into the first port is accelerated through a venturi device disposed in the cavity, and the second check valve is open such that purge vapor flows from the inlet port into the cavity, through the venturi device and mixes with the high-velocity air, through the second check valve into the second port.

Abstract: A navigation device is disclosed that provides navigational guidance to boats needing to cross a boundary line at a milestone event time. Port and starboard laylines and guidelines may be displayed with the boundary line using wind direction data. The port and starboard layline angles may change with the wind direction, while their lengths may represent a distance traversed by the boat tacking at the port and starboard layline angles for a target time period at a target speed. A predictor line may be displayed extending from the boat in the direction in which the boat is traveling and may have a length indicating a distance traversed by the boat at its current speed until the milestone event time. The predictor line length and color may provide feedback regarding whether the boat will cross the boundary too early or too late given its current speed and direction.
