摘要： A method of determining a temperature of a coolant in a coolant circulation system is disclosed. The coolant circulation system includes a coolant flow valve having a valve housing and an expansion element provided in the valve housing for controlling flow of the coolant through the valve housing. According to the method, an ohmic resistance of the expansion element is measured. The temperature of the coolant is determined by correlating the ohmic resistance of the expansion element with the temperature of the coolant.

摘要： A method for correcting a characteristic curve having values corresponding to displacement between a magnetic sensor element and a magnetic ruler of a sensor within a displacement range includes determining whether the characteristic curve has a jump discontinuity by comparing a first value at a first range end to a second value at a second range end and by comparing values between the range ends. Upon determining that the characteristic curve has a jump discontinuity, the method further includes determining the magnitude of the jump discontinuity, defining a decision threshold lying between the first and second values, identifying the values within the range which are lower than the decision threshold, and offsetting the identified values by the magnitude of the jump discontinuity such that the characteristic curve is corrected to eliminate the jump discontinuity, whereby subsequent measurements made by the MR sensor take into account the jump discontinuity magnitude offset.

摘要： A system for detecting the absolute rotational angle of a shaft rotatable more than one revolution includes a drive wheel connected to the shaft to rotate therewith. The drive wheel includes measurement sectors adjacent to one another in a circumferential direction. First and second driven wheels are engaged to the drive wheel. First and second sensors monitor rotational positions of the driven wheels to thereby detect an absolute rotational angle of the shaft. A third sensor monitors a relative angular position of the shaft in relation to a detected one of the measurement sectors to thereby detect the relative angular position of the shaft within one revolution of the shaft. The detected absolute rotational angle of the shaft is refined with the detected relative angular position of the shaft to thereby generate the absolute rotational angle of the shaft with more precision.

摘要： Systems and methods to diagnose valve leakage in a vehicle storing gaseous fuel in two or more vessels. A valve regulating the flow of the gaseous fuel from one of the vessels is closed and reopened, while the other vessels are providing gaseous fuel during a full run. The pressure spike from reopening the valve is analyzed to determine the rate of pressure change. Pressure spikes having a rate of change lower than a threshold parameter are indicative of a leaking valve.

摘要： A method and system for controlling a pressure regulator in a gas storage system using a pressure switch as a pressure measurement device. A controller uses supply pressure data and gas flow demand data to compute a feed-forward control term, and uses data from a pressure sensor downstream of the pressure regulator to compute a feedback control term. During normal operation, with pressure downstream of the regulator oscillating about a set point pressure, on-time and off-time periods of a pressure switch are monitored, and an adaptive control term is computed which balances on-time and off-time. If the pressure sensor fails, excessive switch on-time or off-time will be detected; in response to this, the feedback control term is disregarded, and an adaptive control term is computed which aims to restore balanced on-time and off-time of the switch, thus indicating that the actual pressure is oscillating about the set point.

摘要： A method for producing a spiral link fabric with a plurality of spirals joined to one another in an overlapping manner, with a plurality of seam wires stitched into overlapping regions of adjacent spirals and connecting the spirals to one another to form a flat structure, and with a plurality of packing elements introduced into free cross sections of the spirals, wherein the flat structure runs through a thermofixing operation before or after the introduction of the packing elements. The spirals are joined together to form the flat structure such that, before the thermofixing operation, the result is a clear width, as viewed in the plane of the flat structure, for the free cross sections of the spirals connected to one another to form the flat structure, which clear width is larger than a clear height of the free cross section of each spiral.

摘要： A valve for a pressure vessel system includes a housing having a cavity defined by an inner surface of the housing. The housing further includes a rod aperture and a pair of fluid flow ports. An actuator is disposed adjacent the housing. The valve also includes a piston having a rod coupled to a piston head. The piston head is disposed in the cavity of the housing, and the rod disposed through the rod aperture. The rod is also coupled to the actuator. A ring seal is disposed between the piston head and an inner surface of the housing. The ring seal biases the piston head toward one of the fluid flow ports and seals the one of the fluid flow ports to close the valve when the actuator is deactivated. The ring seal is elastically deformed and the fluid flow ports are opened when the actuator is activated.

摘要： A hydrogen sensor assembly is disclosed. A sensor is disposed within a slotted sleeve and a spiral shaped sensor housing surrounds the sensor within the sleeve. The spiral shape applies a centrifugal force to the fluid stream. This results in separation of liquid water from the fluid stream. The sleeve forms an internal inner perimeter of the spiral housing. The sensor housing includes a first opening to facilitate a fluid communication between the sensing element and a fluid stream through the slotted sleeve.

摘要： A system and method for regulating the pressure within a volume between a pressure regulator and an injector that injects hydrogen gas into the anode side of a fuel cell stack. The method includes delaying a copy of the a pulsed signal that controls the opening and closing of the injector a predetermined period of time and provides a bias signal from a look-up table that is determined by a desired average mass flow of the hydrogen gas flow to the fuel cell stack and the pressure at an upstream location of the hydrogen gas flow from the pressure regulator. The method selects the bias signal as a pressure regulator control signal that controls the pressure regulator when the delayed pulse injector signal is high and selects an arbitrary value at or near zero as the pressure regulator control signal when a delayed pulse injector is low.
