A method for starting operation of a solid polymer fuel cell from a temperature below 0° C. is disclosed that prevents certain problems with ice formation as the fuel cell thaws. During startup, the method involves providing the volumetric oxidant flow at a rate less than two thirds of its maximum when the coolant temperature is near 0° C.

There is provided a method for establishing a connection between a Neutral Host (NH) network and one or more virtual radio access networks (vRANs), under a service level agreement (SLA) therebetween. The method comprises: sending a message to the one or more vRANs, the message including an identity of the NH network and at least a first radio parameter; in response to the message, receiving an identity of the one or more vRANs and at least a second radio parameter; and establishing the connection between the NH network and the one or more vRANs, based on the identity of the one or more vRANs, the identity of the NH network and one of the at least first radio parameter and the at least second radio parameter. The method is implemented in a network node, such as a Distributed Unit of a gNB.

The present invention enables the monitoring of application layer metrics of data packets for subscribers or groups of subscribers. In one embodiment, an edge routing node, such as an edge router or the like, between an access network and a core network will identify a subscriber associated with the incoming data packets and then identify an application layer policy to apply to the data packets. The application layer policy may identify the application layer metrics to monitor, how to analyze the application layer metrics, and perhaps actions to take in light of identifying certain application layer metrics, as well as identifying how, where, and when to report the application layer metrics, or an aggregation thereof. With the present invention, application layer metrics can be obtained and analyzed in real time on a subscriber-by-subscriber basis.

The present invention relates to systems and methods for providing a personalized exchange market, and more specifically, to systems and methods for establishing personalized pledge agreements for uncertain future events or occurrences. In one embodiment, the invention includes a method including the steps of facilitating a pledge offer via a network, the pledge offer specifying an outcome of an uncertain future occurrence, the uncertain future occurrence being independently definable; facilitating an acceptance of the pledge offer over via the network, the acceptance forming a pledge agreement; determining the outcome; and facilitating performance of the pledge agreement based on the outcome.

A method of commencing operation of an electrochemical fuel cell stack from freeze-start conditions is disclosed. The method comprises detecting the temperature of the electrochemical fuel cell stack, detecting the temperature of the ambient environment, and, if the temperature of the electrochemical fuel cell stack is below the freezing temperature of water, (i) supplying fuel and oxidant reactant streams to the electrochemical fuel cell stack, wherein the temperature of at least one reactant stream is above the temperature of the ambient environment, and (ii) drawing electric current from the electrochemical fuel cell stack.

A communications network in which service flows between an end user and the network are transported via a gateway (8) which identifies different service flows and notifies them to a credit control function (12) of the network. The credit control function grants a cache representing an amount of and end user's credit and/or an amount of network resource to the gateway for the identified service flows and provides instructions to the gateway for the identified service flows which enable the gateway to share units of the caches between service flows, for example if there is a threat of a service flow becoming blocked due to a lack of credit in an end user's account.

Mass Air Engine Management Systems For Vintage Style Automobile Engines that uses a Mass Air Flow Sensor positioned above a vertically mounted throttle body and below a traditional vintage style air filter assembly. The Mass Air Flow Sensor may be positioned inside the air filter assembly, as an integral part of the air filter assembly or as an integral part of the vertically mounted throttle body. The result is a vintage appearance.

The present disclosure relates to a method and system in a wireless network for radar detection in certain bands e.g. bands normally used for unlicensed access. In one broad aspect, a method is provided for a network node configured to control wireless transmissions in a frequency band also used for radar transmissions. In that method, the network node controls the wireless transmissions using a transmission cycle pattern defined by a transmit on time and a transmit off time. The method includes after a wireless transmission during the transmit-on time of a first transmission cycle, detecting, during the transmit-off time of the first transmission cycle, at least one radar pulse in the frequency band and extending the transmit off time of a second transmission cycle based on the at least one radar pulse detected. Advantageously, in some implementations, extending the transmit off time when one or more radar pulses are detected provides more time to detect a larger number of pulses which as a result, may improve radar detection accuracy.
