The anode blower is configured for driving circulation through the loop. The switching element is located in at least one of the first path and the combining point and is configured to force the fuel gas to flow through the second path to the fuel exhaust path in the event of failure of the anode blower.

Abstract: A system and method for communicating events between applications. A first application receives event information for an event. A first action is performed by the first application in response to receiving the event information. The first application generates an event message comprising an event name and a message payload. The message payload comprises at least a portion of the event information. The first application publishes the event message by sending the event message to an event message pipeline. A second application may listen for the event message in the event message pipeline, receive the event message from the event message pipeline, and use the message payload to perform a second action, wherein the second action is different from the first action.

Abstract: Apparatuses, methods, and systems are disclosed for beam switching. One apparatus (200) includes a transmitter (210) that transmits (402) information indicating a beam switch request, measurement results, or some combination thereof, wherein the information indicates a list of beams, and the information is based on a trigger event, the measurement results, or some combination thereof.

Abstract: The technology relates to detection of aberrant driving situations during operation of a vehicle in an autonomous driving mode. Aberrant situations may include potential theft or unsafe conditions, which are determined according to one or more signals. The signals are derived from information detected about the environment around the vehicle, such as from one or more sensors disposed on the vehicle. In response to an aberrant situation, the vehicle may take various corrective action, such as rerouting, locking down the vehicle or communicating with remote assistance. The type of corrective action taken may depend on a type of cargo being transported or whether one or more passengers are in the vehicle. If there are passengers, the system may communicate with the passengers via the passenger's client computing devices or by presenting visual or audible information via a user interface system of the vehicle.

Abstract: A refrigeration system includes: a compressor arrangement for compressing gaseous refrigerant from a first pressure to a second pressure, wherein the second pressure comprises a condensing pressure; a plurality of condenser evaporator systems, wherein each condenser evaporator system comprises: a condenser for receiving gaseous refrigerant at a condensing pressure and condensing the refrigerant to a liquid refrigerant; a controlled pressure receiver for holding the liquid refrigerant from the condenser; and an evaporator for evaporating liquid refrigerant from the controlled pressure receiver to form gaseous refrigerant; a first gaseous refrigerant feed line for feeding the gaseous refrigerant at the second pressure from the compressor arrangement to the plurality of condenser evaporator systems; and a second gaseous refrigerant feed line for feeding gaseous refrigerant from the plurality of condenser evaporator systems to the compressor arrangement.

Abstract: A free space optical communication system transmits and receives optical signals in a colorless manner using an optical circulator. The system installs the optical circulator with a single mode (SM) fiber at port 1, a double clad (DC) fiber at port 2, and a multimode (MM) fiber at port 3. The system injects a first optical signal into a core of the SM fiber. The system then routes the first optical signal at port 1, using the optical circulator, into a SM core of the DC fiber via Port 2. Further, the system injects a second optical signal into a first cladding of the DC fiber. The system then routes the second optical signal at port 2, using the optical circulator, into the MM fiber via Port 3.
