摘要:
The level of electrical current produced by a fuel cell during rapid changes in the power demanded by a load, is clamped to the fuel cell's maximum rated current value in order to avoid damage to the fuel cell. When the current supplied to the load by the fuel cell overshoots the maximum rated current value, the fuel cell current is immediately reduced by increasing the fuel cell voltage.

An alternative fuel vehicle having a fuel economy control module with associated logic that allows the vehicle to operate in a fuel economy mode based on a desired fuel economy preference. The fuel economy control logic is in electrical communication with a vehicle system controller (VSC) and may be integrally formed as a sub-module within the VSC. A fuel economy control switch controlled by the fuel economy control logic toggles between an on and an off position to enable or disable a fuel economy mode. A fuel economy control selector allows a user to select a desired fuel economy mode preference once the fuel economy control switch is on. The fuel economy mode selected represents a predefined desired fuel economy preference such as a distance per amount of fuel consumed, or alternatively, a percentage of a balance between a fuel economy operation and a fuel performance operation.

摘要:
Calls which fail in the ways described above will typically result in a server (GK, MGC, RS or Ps for example) in the network issuing a failure message. This message typically provides one of two options; call forwarding to a central answering position or call clearing. The message does not allow for any more intelligent decisions to be taken and information about the reason for failure is irretrievably lost. By enhancing the message with an indication of the reason for failure and an optional recommendation for handling, the processing of such failed calls may be improved. For example, a gateway which receives the failure message may simply act in the usual way and either forward or clear the call. However with the enhanced indication, it may instead choose to carry out alternative actions such as collect more digits and retry at end of dial. If overlap signalling is being provided and the IP cloud is not fully overlap compatible, the gateway might also do an overlap to en bloc conversion. Another option is to collect at least one more digit and retry the call. This typically works well if overlap signalling is not used.
