  • Patent number: 10330508
    Abstract: A method of ultrasound flow metering includes applying a first and second pulse train to an ultrasound transducer pair (T1, T2) positioned for coupling ultrasonic waves therebetween. Responsive to the first pulse train applied to T1, T1 transmits an ultrasonic wave received as received ultrasonic wave (R12) by T2 after propagating through fluid in a pipe. Responsive to the second pulse train applied to T2, T2 transmits an ultrasonic wave received as received ultrasonic wave by (R21) T1 after propagating through the fluid. During the pulse trains, R12 and R21 build up in amplitude to provide excitation portions. The pulse trains are terminated, so that R12 and R21 decay as a damped free oscillation. Windowing is applied to R12 and R21 to generate windowed portions. A signal delay between t12 and t21 (?TOF) is calculated using only windowed portions, and a fluid flow is calculated from the ?TOF.

  • Patent number: 10279702
    Abstract: A technique of diagnosing a fuel cell stack is provided. In particular, current and voltage of a fuel cell stack are measured during driving of a fuel cell vehicle and the current and voltage are sequentially stored. It is then determined based on the stored current whether the vehicle is being operated at constant current. Different factors are analyzed depending on whether the vehicle is being operated at constant current, and then it is determined whether the fuel cell stack is in a normal state. A moisture supply into the fuel cell stack is calculated if it is determined that the fuel cell stack is not in the normal state. Based on the calculated moisture supply, whether the fuel cell stack is in a dryout state is diagnosed.

An example method may involve receiving a log of sensor data that may include sensor values output by given sensors of a mobile device over a time period, and at least one location estimate for at least one respective point in time within the time period. One or more processors may then determine, using the sensor values, an estimated trajectory that includes a plurality of computed ground-truth locations of the mobile device over the time period. Further, the method may involve determining a difference between a given location estimate and a computed ground-truth location of the plurality of computed ground-truth locations. And the method may involve providing an output indicative of whether the determined difference satisfies a predetermined threshold.
