  • Patent number: 10830573
    Abstract: The purpose of the present invention is to measure a size of a liquid droplet easily and in a short period of time by combining outputs of multiple types of liquid droplet detectors having different size dependencies of a liquid droplet of detection signals. In one embodiment of the present invention, in the detector having a narrow gap width shown in FIG. 5(a), the electrodes are electrically conducted by the attachment of a small liquid droplet. On the other hand, in the detectors with a wide gap width shown in FIGS. 5(b) and 5(c), the electrodes are not electrically conducted unless a liquid droplet having a larger size is attached. By utilizing this, the size of a liquid droplet is determined. In a case where the liquid droplet is water, as a liquid droplet detector, for example, a detector of a type that detects a galvanic current by a cell formed by the attachment of water between the electrodes made of different kinds of metals may be used.

  • Patent number: 10809099
    Abstract: A device rotates at least one static magnetic field about an axis, producing a rotating magnetic dipole field, and is movable in relation to the surface of the ground. The field is periodically sensed using a receiver to produce a receiver output responsive to the field. A positional relationship between the receiver and the device is monitored using the output. In one aspect, changing the positional relationship, by moving the device nearer to a boring tool which supports the receiver, causes an increase in accuracy of depth determination. In another aspect, determination of an actual overhead position of the boring tool, and its application, are described. Use of a plurality of measurements over at least one-half revolution of each magnet is disclosed. Establishing a surface radial direction toward a boring tool and resolution of multi-valued parameters is described.

  • Patent number: 10802072
    Abstract: Systems and methods for measuring direct current (DC) voltage of an insulated conductor (e.g., insulated wire) are provided, without requiring a galvanic connection between the conductor and a test electrode or probe. A non-contact DC voltage measurement device may include a conductive sensor that is mechanically oscillated. The insulated conductor under test serves as a first conductive element or electrode of a coupling capacitor, and the vibrating conductive sensor serves as a second conductive element or electrode of the coupling capacitor. The oscillation of the conductive sensor provides the coupling capacitor with a time-varying capacitance value. The measurement device detects current flowing through the coupling capacitor, and determines the DC voltage in the insulated conductor using the detected current and the time-varying capacitance. The determined DC voltage may be output to a display or transmitted to an external system via a wired or wireless connection.
