  • Patent number: 8954281
    Abstract: A system for testing a wellbore fluid includes a test chamber having first and second platens therein. The chamber is in a thermally insulating enclosure. The enclosure includes a heating element. The platens simulate response of the wellbore fluid through an hydraulically induced fracture in subsurface rock formation. The system includes means to control a distance between the platens. A pump introduces the wellbore fluid into a space between the platens and another pump introduces a pressure test fluid into contact with the wellbore fluid. A respective pressure sensor is in fluid communication with a discharge side of each pump, and a sensor is included to measure a parameter related to the position of the second platen or the space between the platens. A data acquisition and control device is configured to detect signals from the respective pressure transducers and the sensor.

  • Patent number: 8930167
    Abstract: Techniques and tools for rating computer products are described. For example, software ratings are based on subjective evaluations to determine computer system requirements for a positive user experience, while a computer running a capability tool rates a computer system's (or hardware component's) ability to run software. A capability rating for hardware is determined by comparing a set of features and performance results with capability rating requirements. In another aspect, a capability rating is communicated using a standardized presentation. In another aspect, capability rating level requirements are proposed (e.g., by a ratings board) and then finalized. A capability rating level is determined for computer products (e.g., by a testing organization) based on the finalized requirements and analysis of the products (e.g., by a computer running a capability tool).

  • Patent number: 8924164
    Abstract: An apparatus and a method for ultrasonic testing obtains high-resolution and high-S/N ratio testing results by driving a number of piezoelectric elements using fewer pulsers and receivers in comparison with the number of elements composing an array transducer. A sensor information setter sets a plurality of piezoelectric element groups used for transmission and a plurality of piezoelectric element groups used for reception among the plurality of piezoelectric elements composing an ultrasonic array transducer. A computer transmits an ultrasonic wave from the element cluster set for transmission, and stores an ultrasonic wave received by the element cluster set for reception. The procedure is repeated including different element cluster sets for transmission and reception to obtain first receive signals. The first receive signals are summed to obtain a second receive signal; and the second receive signal is displayed with reference to the sensor center position on a display unit.

  • Patent number: 8918285
    Abstract: One example of testing for water contamination in geographic areas to determine a risk of water contamination includes determining a risk of water contamination. A computer system receives identification of a geographic area in which a risk of water contamination is to be determined. In response, the system determines a number of potential complaints of water contamination in the geographic area by applying the number of one or more correlated sources of water contamination located in the geographic area. The system determines a risk factor representing a risk of water contamination in the geographic area based, in part, on the number of potential complaints. The system can provide the risk factor as the risk of water contamination in the geographic area.

  • Patent number: 8918286
    Abstract: An optical fiber is provided with a first measurement portion and a second measurement portion. The first measurement portion is provided with a heater and a hygroscopic layer made of a resin in which a material having a deliquescent property is dispersed. Meanwhile, the second measurement portion is provided with the heater and a non-hygroscopic layer having a lower moisture absorption capacity than the capacity of the hygroscopic layer. The heater is brought into heat generation by being supplied with electric power, and temperatures at the second measurement portion and temperatures at the first measurement portion are measured with a temperature measurement device. Then, an analyzer calculates a humidity based on an integrated value of differences between the temperatures at the first measurement portion and the temperatures at the second measurement portion.

  • Patent number: 8914246
    Abstract: Methods and systems to provide baseline measurements for aging compensation for a display device are disclosed. An example display system has a plurality of active pixels and a reference pixel. Common input signals are provided to the reference pixel and the plurality of active pixels. The outputs of the reference pixel is measured and compared to the output of the active pixels to determine aging effects. The display system may also be tested applying a first known reference current to a current comparator with a second variable reference current and the output of a device under test such as one of the pixels. The variable reference current is adjusted until the second current and the output of the device under test is equivalent of the first current. The resulting current of the device under test is stored in a look up table for a baseline for aging measurements during the display system operation.

  • Patent number: 8855942
    Abstract: A control strategy for bleeding an anode side of fuel cell stack in a fuel cell system that improves water management and addresses durability and performance concerns. The method includes determining when to begin the anode bleed, typically by estimating or measuring the amount of nitrogen in the anode side of the stack. The method also includes determining when to end the anode bleed based on the volume of gas that has been bled. The method determines the mole flow rate of the anode gas flowing through a bleed valve, integrates the mole flow rate to get the number of moles of the gas that have passed through the bleed valve, determines a desired amount of moles to be bled, and ends the bleed when the actual number of moles of the gas equals the desired number of moles of the gas.

  • Patent number: 8825436
    Abstract: A spatially distributed MEMS inertial sensor array is designed to reduce or cancel measurement errors and to increase the signal detection accuracy. By combining the measurements from a pair of sensors having sensing axes in two different, non-orthogonal directions, the correlated error due to the environmental changes are cancelled or reduced and the uncorrelated random noise is also reduced by the square root of two. By sequentially sampling the sensor array in the time domain, the number of the ADC circuits can be largely reduced. A two dimensional signal processing method is used to process the sensor array output data, in order to further reduce the remaining errors. Namely, one dimension uses the outputs from multiple spatially distributed sensor sets and the other dimension is the time domain. The signal to noise ratio is increased by using the signal correlation in both the spatial domain and the time domain.
