Abstract: Improved throughput is provided in a spacecraft TDMA cellular communications system by introducing a standby state, in addition to the idle and transfer states, of the medium access control (MAC) protocol, which controls the transfer of data over the radio interface between the network and the user terminals. The terrestrial locations include mobile user terminals and gateways which provide connections to the land line telephone system and/or the land packet data network i.e. Internet service provider. Each of the terrestrial terminals and gateways include a MAC to control the transmitting and receiving of data between the gateway and user terminals. Since packet data is bursty, multiple transitions occur between the idle and transfer states during data transfers. The new standby state maintains synchronization, reducing the transition time to the data transfer state by comparison with the transition time from an idle state where the network does not maintain user synchronization.

Abstract: Misfire detection techniques for a hybrid electric vehicle (HEV) including an internal combustion engine and an electric motor involve utilizing a crankshaft speed sensor configured to generate a crankshaft speed signal indicative of a rotational speed of a crankshaft of the engine that is coupled to the electric motor via a flywheel. The techniques also utilize a controller configured to control the electric motor to provide a vibrational response to dampen disturbances to the crankshaft, receive the crankshaft speed signal, selectively modify the crankshaft speed signal to obtain a modified crankshaft speed signal, and detect a misfire of the engine based on the modified crankshaft speed signal and a set of thresholds including at least one of a negative misfire threshold and a positive vibrational response threshold.

Abstract: A method of diagnosing rationality of a humidity sensor output signal determines that the humidity sensor output signal has passed a rationality diagnostic if the output signal is changing sufficiently. If the output signal is not changing sufficiently, the method determines whether it should be changing sufficiently by whether a humidity capacity index determined based on temperature and pressure local to the humidity sensor is changing sufficiently. If the humidity capacity index is changing sufficiently and the humidity sensor output signal is not, the method determines that the humidity sensor output signal has failed a diagnostic check. Upon determining that the humidity sensor output signal has failed the diagnostic check a predetermined number of times, the method determines that the humidity sensor output signal has failed the rationality diagnostic.
