A materialized view is created on a base table, and continuously maintained, such that as changes are made to the base table, the materialized view is correspondingly updated. The database system records metadata identifying regions of the base table that have already been materialized. Subsequently, these invalidated regions are rematerialized. Queries ensure up-to-date results by combining data from the materialized view with results calculated at query time on the base table. Invalidation records and completion thresholds are used to determine which results should use records from the materialized table and which should be computed from records from the base table. |

Method for improving accuracy of touch screen event analysis by use of spatiotemporal touch patterns
A method of classifying touch screen events uses known non-random patterns of touch events over short periods of time to increase the accuracy of analyzing such events. The method takes advantage of the fact that after one touch event, certain actions are more likely to follow than others. Thus if a touch event is classified as a knock, and then within 500 ms a new event in a similar location occurs, but the classification confidence is low (e.g., 60% nail, 40% knuckle), the classifier may add weight to the knuckle classification since this touch sequence is far more likely. Knowledge about the probabilities of follow-on touch events can be used to bias subsequent classification, adding weight to particular events. |

The process fluid temperature estimation system includes measurement circuitry coupled to the sensor capsule and configured to detect a characteristic of the at least one temperature sensitive element that varies with temperature and provide sensor capsule temperature information and a controller coupled to the measurement circuitry, the controller being configured to obtain a reference temperature and employ a heat transfer calculation with the reference temperature and the sensor capsule temperature information to generate an estimated process temperature output. The process fluid temperature estimation system includes a mounting assembly configured to mount the process fluid temperature estimation system to the external surface of the process pipe, wherein a portion of the mounting assembly is offset from the external surface of the process pipe. |

Scale composition determination system, scale composition determination method, and program
A scale composition determination device (10) determines that Fe2O3 has been generated in the outermost layer of a scale (SC) in the case where the absolute value of a difference between temperatures of a steel material SM measured by radiation thermometers (20a, 20b) is equal to or more than a predetermined temperature, and determines that Fe2O3 has not been generated in the outermost layer of the scale (SC) in the case where the absolute value of the difference between the temperatures of the steel material SM measured by the radiation thermometers (20a, 20b) is not equal to or more than the predetermined temperature. |

Spectral phase interference device and system
The present application provides a spectral phase interference device and system for addressing the problem of low stability and compactness with prior art spectral phase interference devices. In the device or system provided in the present application, the optical element for generating the pulse pair to be measured consists of only a birefringent crystal and the adjustment of two-step phase shift is also completed by only a broadband quarter-wave plate. Therefore, wide application of optical elements such as pulse stretchers, retarders, optical splitters and mirrors as in prior art devices is avoided, thereby significantly simplifying the overall device's structure and resulting in enhanced stability and compactness at the same time. |

Integrated circuit for spectral imaging system
An integrated circuit for an imaging system is disclosed. In one aspect, an integrated circuit has an array of optical sensors, an array of optical filters integrated with the sensors and configured to pass a band of wavelengths onto one or more of the sensors, and read out circuitry to read out pixel values from the sensors to represent an image. Different ones of the optical filters are configured to have a different thickness, to pass different bands of wavelengths by means of interference, and to allow detection of a spectrum of wavelengths. The read out circuitry can enable multiple pixels under one optical filter to be read out in parallel. The thicknesses may vary non-monotonically across the array. The read out, or later image processing, may involve selection or interpolation between wavelengths, to carry out spectral sampling or shifting, to compensate for thickness errors. |

High-capacity weighing module
A high-capacity weighing module has a top plate weldment (10), a bottom plate weldment (30) and a pressure-bearing assembly (20) that is between the top and bottom plate weldments. Motion between the respective top and bottom plate weldments is restricted. This structure aids in easy installation and replacement of a sensor, and integrates the functions of anti-overturning and 360° inspection, and bottom stop. This makes the weighing module much more convenient to install than a conventional high-capacity module, and has a better safety function. The weighing module has advantage in terms of a simplified product structure, reduced cost of manufacture and maintenance, uncomplicated installation procedure, and higher safety and protection. |

Precision ADC sampling clock for high accuracy wireless guided wave radar
A level transmitter includes an analog-to-digital convertor clock signal generator that receives a transmitter clock signal that is used to establish when an incident signal is transmitted toward a material boundary. The analog-to-digital convertor clock signal generator uses the received transmitter clock signal to generate an analog-to-digital convertor clock signal. An analog-to-digital convertor samples an analog waveform based on the analog-to-digital convertor clock signal and generates a digital value for each sample of the analog waveform. An analysis module analyzes the digital values to determine a distance to the material boundary. |
