  • Patent number: 8335658
    Abstract: The present invention describes a method for determining a value for the temperature, radiation, emissivity, transmissivity and/or reflectivity of an object (2) such as a semiconductor wafer in a rapid heating system (1), wherein an output signal from a radiation detector (50) which records temperature radiation from the object is used as a measurement value, and wherein prediction values for the measurement values are calculated in a model system (100). The development over time of the measurement values is compared with the development over time of the prediction values and the measurement value is corrected if the difference exceeds predetermined threshold value.

  • Patent number: 8332163
    Abstract: Methods of determining a quantity of rotor slots in an induction motor are disclosed. An approximate slip is calculated according to an approximate slip function. A fundamental frequency is calculated from a representation of the voltage signal. A saliency frequency is calculated from a representation of the current signal. For each rotor slots index in a set of rotor slots indices, a slip estimate is calculated according to a slip estimation function. A slip estimation error signal is calculated. A rotor slots performance surface representative of an aggregate of the slip estimation error signals is calculated. A rotor slots quantity equal to the rotor slots index corresponding to a minimum of the rotor slots performance surface over at least a portion of the set of the rotor slots indices is defined.

  • Patent number: 8296086
    Abstract: A new measurement system, with two receiver channels per measurement port, has been developed that provides absolute magnitude and absolute phase relationship measurements over wide bandwidths. Gain ranging is used at RF to provide optimum noise performance and a swept YIG preselector filter is used to avoid spurious signals. A new absolute vector error correction method is used to calibrate the measurement system in order to allow for absolute vector measurements, and it also removes the time-varying responses caused by the swept YIG preselector filters. A quasi-reciprocal mixer with a characterized non-reciprocal ratio is used to provide the absolute calibration standard. The two receiver channels can be adapted to a wide variety of applications, including wide bandwidth vector signal analyzer measurements, mixer measurements, and harmonic measurements. The two-channels can also be used as an absolute calibrated transmitter/reflectometer.

  • Patent number: 8280639
    Abstract: Efficiency of a hydraulically driven system is evaluated by monitoring the change in ratio of output torque to input hydraulic pressure. The hydraulic pressure data is received from a hydraulic sensor. The torque data is received from a load cell receiving a force transmitted to it by a back-up wrench. Filters are applied to the data to obtain peak levels of torque and hydraulic pressure. A ratio is generated for each process associated with a rod or other elongated member based on peak torque and hydraulic pressure levels achieved during the process. The ratio is stored and compared to historical ratios to determine if the ratio has changed more than a predetermined amount over time. A similar evaluation can be achieved by comparing speed generated on the elongated member by the hydraulically driven system to the current level controlling the flow of hydraulic fluid to the hydraulically driven system.

  • Patent number: 8260576
    Abstract: An exhaust gas sensor abnormality diagnostic device includes an exhaust gas sensor, and a judgment means that judges whether execution conditions are established for making an abnormality diagnosis of element breakage in the exhaust gas sensor. The device also includes an abnormality diagnosis means that makes the abnormality diagnosis in accordance with an output signal generated by the exhaust gas sensor. Further, when the integrated value of intake air amounts of an internal combustion engine is not smaller than a predetermined value, the judgment means judges that the execution conditions are established. The abnormality diagnosis means cancels the establishment of the execution conditions when an intake air amount of the internal combustion engine remains less than a predetermined value for a predetermined period of time.
