  • Patent number: 8456159
    Abstract: A stabilized field sensor apparatus collects field data, in particular magnetic field data, with reduced motion noise. The apparatus includes a tear drop shaped housing, a tow frame in the housing, a plurality of vibration isolating dampers spaced around the frame, a base assembly mounted to the dampers, a support pedestal having a bottom end fixed to the base assembly and an upper free end, a single spherical air bearing connected to the upper free end of the pedestal, an instrument platform with a lower hollow funnel having an upper inside apex supported on the air bearing for a one point support, principal and secondary gyro stabilizers for maintaining pivotal and rotational stability, and at least one field sensor mounted to the instrument platform for collecting the field data while being stabilized against motion noise including vibration, pivoting and rotation from the base assembly, from the tow frame and from the housing.

  • Publication number: 20130120199
    Abstract: A fringe-effect antenna module includes coupling structure configured to couple the module to a communications vault that is disposed substantially at ground level. A support structure (which preferably includes an electronics unit) is coupled to the coupling structure, and at least one antenna element is coupled to the support structure. A metallic deflector is coupled to at least one of (i) the coupling structure and (ii) the support structure. The metallic deflector has an edge that is positioned substantially parallel to the ground so as to cause a fringe effect upon the RF signals of the antenna to cause those RF signals to bend in a direction toward the ground.

  • Patent number: 8385821
    Abstract: An underwater communications system is provided that transmits electromagnetic and/or magnetic signals to a remote receiver. The transmitter includes a data input. A digital data compressor compresses data to be transmitted. A modulator modulates compressed data onto a carrier signal. An electrically insulated, magnetic coupled antenna transmits the compressed, modulated signals. The receiver that has an electrically insulated, magnetic coupled antenna for receiving a compressed, modulated signal. A demodulator is provided for demodulating the signal to reveal compressed data. A de-compressor de-compresses the data. An appropriate human interface is provided to present transmitted data into text/audio/visible form. Similarly, the transmit system comprises appropriate audio/visual/text entry mechanisms.

  • Patent number: 8378908
    Abstract: An electromagnetic antenna for Measurement-While-Drilling (MWD) applications is disclosed. The antenna can include several array elements that can act alone or together in various measurement modes. The antenna elements can be disposed in tool body recesses to be protected from damage. The antenna elements can include a ferrite plate crossed or looped by independent current carrying conductors in two or more directions forming a bi-directional or crossed magnetic dipole. Although disclosed as a MWD system conveyed by a drill string, basic concepts of the system are applicable to other types of borehole conveyance.

  • Patent number: 8350719
    Abstract: A meter pit lid plug and bracket assembly configured to suspend a transmitter plug inside a meter pit is provide. The meter pit lid plug and bracket assembly includes a plug and a bracket. The plug includes a head and a stem that extends from the head. The stem is also configured to extend through a hole in a meter pit having a top surface. The head is sized to rest on the top surface of the meter pit lid and is configured to hold the stem in the hole. The bracket is configured to hold the transmitter plug inside the meter pit. The stem is selectively engageable with the base so that when the stem is connected with the base, both the plug and bracket are configured to hold and suspend the transmitter plug inside the meter box.
