If the expected ratio corresponds to the stored ratio and the stored ratio corresponds to the currently ratio, the current measured value is valid. If the expected ratio corresponds to the stored ratio and the stored ratio deviates from the current ratio, a disturbance is present. If the expected ratio deviates from the stored ratio, the validity for this measured value is not evaluated.

  • Patent number: 9322735
    Abstract: In some embodiments, at least one processor is employed to determine a boundary of a survey area. Data representative of the locations of measurement points adjacent to or outside of the survey area is received, as well as data representative of wind direction at the measurement points. The boundary of the survey area is determined according to the data representative of wind direction and a maximum detection distance value representative of an estimated maximum distance from a potential gas leak source at which a gas leak from the potential source can be detected. The boundary is determined such that if the potential gas leak source is located in the survey area and has a rate of leakage meeting a minimum leak rate condition, then an estimated probability of detection of the gas leak at one or more of the measurement points satisfies a probability condition.

  • Patent number: 8843281
    Abstract: Seed meters, agricultural planters, and methods of planting seed are provided. Such meters, planters, and methods may include a housing defining a chamber, a seed disc rotatably coupled to the housing and at least partially positioned within the chamber with the seed disc adapted to engage a seed, and a sensor for detecting a characteristic of the seed after the seed disengages the seed disc and before the seed exits the seed meter. The sensor may be coupled to a seed chute of the seed meter and may detect a wide variety of seed characteristics such as seed position within the seed chute, seed size, and seed shape. The seed characteristic may be used to adjust operation of the seed meters, agricultural planters, and methods. In some instances, the adjustment may be manual. In other instances, the adjustment may be automatic.

  • Patent number: 8828737
    Abstract: Methods for using focused light scattering techniques for the optical sensing of biological particles suspended in a liquid medium are disclosed. The optical sensing enables one to characterize particles size and/or distribution in a given sample. This, in turn, allows one to identify the biological particles, determine their relative particle density, detect particle shedding, and identify particle aggregation. The methods are also useful in screening and optimizing drug candidates, evaluating the efficacy and dosage levels of such drugs, and in personalized medicine applications.

  • Patent number: 8637803
    Abstract: An apparatus and method for measuring optical forces acting on a trapped particle. In one implementation the apparatus and method are adaptable for use in the optical train of an optical microscope that is configured to trap, with a single light beam, a particle suspended in a suspension medium between an entry cover and an exit cover of a chamber positioned on or within the microscope. The apparatus and method involves the use of a single collection lens system having a numerical aperture designed to be greater than or equal to an index of refraction index of the suspension medium intended to suspend the particle in the chamber which is placeable at or near the exit cover of the chamber of the microscope.

  • Patent number: 8618465
    Abstract: A seed sensor system determines the position of the seed relative to the seed tube as the seed passes the sensor. The position of the seed as well as the speed of the planter and the position of the seed tube above the planting furrow are used to calculate trajectory of the seed into the furrow from which the seed spacing is predicated. By sensing the seed in both X and Y directions in the seed tube, the sensor is better able to determine multiple seeds as well providing more precision to the seed population.

  • Publication number: 20130248693
    Abstract: A particle detection system is provided, including a sensing chamber having an inlet nozzle, an outlet nozzle, and an interrogation zone defined therebetween. Particles in a sampled environmental gas are prevented from escaping the interrogation zone by pressurizing the sensing chamber such that the pressure therein is higher than that in the outlet nozzle. This is accomplished by providing a source of extra gas to the sensing chamber, for example, by diverting gas from an inlet flow path directly to the sensing chamber.

  • Patent number: 8542882
    Abstract: The invention relates to a method for determining flow conditions in a measured volume permeated by a fluid spiked with optically detectable particles. A plurality of two-dimensional images of the particle distribution is thereby created at each of a plurality of times, an estimated particle distribution is determined therefrom, and a three-dimensional displacement vector field is calculated. According to the invention, a transfer function for the image detectors used is first determined, by means of which the real distribution is mapped by the image detector. Starting from a roughly estimated initial distribution, and by means of the transfer function, virtual images of the estimated distribution are then calculated and compared to the associated real images. The estimated distribution is modified in an iterative method until sufficient matching of the virtual and real images has been achieved.
