Abstract: In one general aspect, various embodiments of the present invention can include a motorized surgical cutting and fastening instrument having a drive shaft, a motor selectively engageable with the drive shaft, and a manual return mechanism configured to operably disengage the motor from the drive shaft and retract the drive shaft. In at least one embodiment, a surgeon, or other operator of the surgical instrument, can utilize the manual return mechanism to retract the drive shaft after it has been advanced, especially when the motor, or a power source supplying the motor, has failed or is otherwise unable to provide a force sufficient to retract the drive shaft.

Abstract: A system is configured to store a relationship data set of a plurality of diagnostic estimators and a plurality of failure modes, each failure mode represents a type of failure that can occur with a sensor or a vehicle component of a vehicle system, each diagnostic estimator is associated with a respective subset of the failure modes, each subset defines a control space within the vehicle system that contains at least one of (i) one or more sensors or (ii) one or more vehicle components. The system is configured to store a healthy diagnostic vector regarding nominal operational parameters of the vehicle system; acquire diagnostic information regarding current operational parameters of the vehicle system to generate an error diagnostic vector; apply the error diagnostic vector to the healthy diagnostic vector to generate a ratio diagnostic vector; and apply the ratio diagnostic vector to generate a value for each failure mode.

Abstract: A fuel cell temperature-measuring system includes a coolant source that provides coolant at a total coolant flow rate and an initial coolant temperature. A flow field plate defines peripheral flow channels and active area flow channels through which coolant flows. The flow field plate is adapted to be positioned in a fuel cell stack between individual fuel cells. A total coolant flow provided to the common input divides into a bypass flow that flows through the peripheral flow channels and an active area flow that flows through the active area flow channels. The bypass flow combines with the active area flow to emerge from the common output with an output coolant temperature. The fuel cell temperature-measuring system includes a temperature sensor that measures the output coolant temperature from the common output. Finally, a temperature estimator estimates an active area coolant temperature from the output coolant temperature.

Abstract: A fuel cell voltage recovery system includes a fuel cell stack having a fuel cell stack voltage between fuel cell stack terminals which is at a first voltage during normal fuel cell operation. The system also includes a high voltage electrical system operating at a first DC operating voltage that is generally higher than the first voltage of the fuel cell stack. A boost converter in electrical connection with the fuel cell stack and the high voltage electrical system operates in a normal control mode to transfer electrical power from the fuel cell stack to the high voltage electrical system through regulation and control of average stack output current (boost input current) during normal fuel cell operation. The boost converter can also operate in a voltage control mode to lower the fuel cell stack voltage to a second voltage that is lower than the first voltage. A FCS controller controls the operation of the boost converter.
