Abstract: A metrology unit includes an integrated reference target with which an automated system check process is performed. The automated system check process includes measuring a feature on the reference target and determining if the measurement is within a desired specification for the metrology unit. When the metrology unit fails the automated system check, or if otherwise warranted, an automated diagnosis process may be performed using the same integrated reference target. The automated system check and automated diagnosis may be optimized based on correlations between parameters of the automated qualification and parameters of the automated diagnosis. Similarly, the measurement of a processed wafer may be optimized based on a correlation between parameters of the metrology of the processed wafer and parameters of the automated system check.

Abstract: Bridge circuits have half bridges formed of sensor elements, which vary respective impedances in accordance with a rotating magnetic field generated by a rotary object. A control unit acquires output signals produced from intermediate points of the half bridges, and calculates a rotation angle of the rotary object based on the output signals. The control unit determines that the output signal is abnormal, if a calculation value of the output signal calculated based on at least four output signals is outside a predetermined range. The control unit thus determines which one of the output signals has become abnormal due to failure or the like.

Abstract: A method records and transmits data between a transmission unit that has a first antenna and a measurement module which has a sensor for recording measured variables and converts the measured variables into electric signals. Data is bi-directionally transmitted between the measurement module and the transmission unit located within the near field of the measurement module by use of a second antenna that is arranged on the measurement module.

The digital oscilloscope comprises a trace intensity synthesizer including a first intensity memory and a second intensity memory. The controlling procedure performed by the digital oscilloscope includes: a determining step for determining whether the time interval of a trigger signal is larger than a predetermined threshold, a first fluorescence processing step performed when the time interval of a trigger signal is equal to or less than the predetermined threshold, and a second fluorescence processing step performed when the time interval of a trigger signal is larger than the predetermined threshold. The digital oscilloscope can automatically select the dynamic fluorescence effect to pay attention to the long-term variation of a signal when the triggering rate is low, and the static fluorescence effect to pay attention to the rapid variation of a signal when the triggering rate is high.

Abstract: A computer-implemented method, system, and/or computer program product detects contaminants in a pipe that is transporting a known fluid. A baseline vibration pattern is established from readings generated by a smart sensor that is affixed to the pipe. This baseline vibration pattern is caused by a flow of the known fluid as the known fluid travels through the pipe in an unadulterated form. Subsequent readings from the smart sensor are taken to generate a new vibration pattern. In response to the new vibration pattern being different, beyond a predefined range, from the baseline vibration pattern, the new vibration pattern is matched to a known vibration pattern in order to identify a specific contaminant of the known fluid.

The dimensions of the four-dimensional volume may include a trace number dimension, a time dimension, a shot number dimension, and a cable number dimension. The random noise attenuation filter may filter portions of the acquired seismic data if the seismic data is not correlated with respect to other seismic data in the four dimensional volume.

Abstract: A detection apparatus includes a transmitter to generate a detection signal, and a coil assembly including a transmit coil and a receive coil. The transmit coil transmits the detection signal toward an object to be detected, with the object to be detected emitting a target signal in response to the transmitted detection signal. The receive coil receives the target signal emitted from the object along with an undesired coupling signal from the transmit coil. A matching network is coupled to the transmitter and generates an adjusted detection signal by adjusting a profile of the detection signal to match a profile of the undesired coupling signal. An output stage has a first input coupled to the receive coil to receive the target signal and the undesired coupling signal, and a second input coupled to the matching network to receive the adjusted transmit signal. The output stage subtracts the adjusted detection signal from the target signal and the undesired coupling signal so that the target signal remains.
